Luoyang  MC Bearing Produce Kinds of Slewing Bearing, Cross Roller Bearing.

Crossed roller bearings play a crucial role in machinery by providing support and reducing friction. For applications that require high speed and need to withstand radial, axial, and moment loads, crossed roller bearings are generally preferred.

The inner and outer rings of crossed roller bearings are minimized in size, especially in ultra-thin structures, making them close to the limits of small dimensions. They also possess high rigidity. As a result, they are widely used in industrial robot joints or rotating parts, rotating worktables in machining centers, rotating parts of mechanical arms, precision rotary worktables, medical instruments, measuring instruments, IC manufacturing devices, and other applications.

The rolling elements in crossed roller bearings are typically arranged in a crossed arrangement using cylindrical or tapered rollers in a single raceway groove. The rollers are separated by brass retainers or engineering plastic isolating blocks, which provide high rotational accuracy, large load-bearing capacity, small overall dimensions, high rotational speed and rigidity. Crossed roller bearings have a wide range of applications and are suitable for industrial robot joints, CNC rotary tables, DD motors, medical equipment, and other fields.

2. Characteristics and Advantages of Crossed Roller Bearings

1. Crossed roller bearings have a sturdy and inseparable inner and outer ring structure that can achieve high rigidity and high precision without being influenced by the surrounding structure. The bearings are suitable for medium to high speeds, and they have isolating blocks between the cylindrical rollers to provide smooth rotation.

2. Crossed roller bearings have the characteristics of high rigidity, accuracy, and easy installation. The mounting holes allow them to be quickly fixed to components. This type of bearing also has isolating blocks between the cylindrical rollers.

3. Crossed roller bearings have a smaller outer diameter and narrower width. They can be selected when high performance and minimal space occupation are required.

Since crossed roller bearings are divided into two parts, the outer or inner ring is fixed together after installing the rollers and retainers. As a result, they are very easy to install. In addition, crossed roller bearings have high precision, with accuracy reaching P4/P2 levels, and smaller dimensions, making the host machine more space-saving.

3. Classification of Crossed Roller Bearings

– SX Type (Inner ring integral, outer ring separable, ultra-thin): Under the same shaft diameter, this type has smaller cross-sectional dimensions compared to the HRB type. Due to its ultra-thin design, it does not have mounting holes on the outer or inner ring, and flanges and support seats are needed for installation. It is suitable for applications requiring rotation of the inner ring.

Type: SX011814,SX011818,SX011820,SX011824,SX011828,SX011832,SX011836,SX011840,SX011848,SX011860,SX011868
,SX011860,SX0118/500

– RU Type (Inner and outer ring integral, with mounting holes): Both the outer and inner rings have mounting holes, so flanges and support seats are not required during installation. Additionally, because the outer and inner rings are both integral structures, installation has almost no impact on performance, ensuring stable rotational accuracy and torque. It is suitable for situations where both the outer and inner rings rotate.

– RAU Type (Inner and outer ring integral, ultra-thin): This type is a compact version of the HRB type, with reduced thickness of the inner and outer rings. It is most suitable for lightweight and compact designs, such as robot and mechanical arm rotating parts. It can be used in situations requiring rotation of both the outer and inner rings.

– RBH Type (Inner and outer ring integral, ultra-thin): It features an ultra-thin design with no mounting holes on the outer or inner ring, so flanges and support seats are required for installation. Due to its integral structure for both the outer and inner rings, installation has no impact on performance, ensuring stable rotational accuracy and torque. It is suitable for situations where both the outer and inner rings rotate, but with requirements for small dimensions.

– RB Type (Inner ring integral, outer ring separable): This type is the basic type of crossed roller bearings. The outer ring is divided into two pieces, while the inner ring is an integral structure. It is most suitable for applications that require high precision in the rotation of the inner ring.

Bearing types are varied, in various mechanical equipment in the field of the application of the effect is not the same, different needs constitute a different bearing production conditions. In some aspects of the need to use more and better performance of the quality of bearings in the production and processing of the method used in the process of joining the ultra-precision machining process. The so-called precision machining process refers to the machining accuracy and surface finish higher than the corresponding machining method of various processing technology.

In the rolling bearing manufacturing process, super-fine is the last procedure of bearing ring processing, it is for reducing or eliminating the round deviation left over from grinding processing, repairing the shape error of the groove, refining its surface roughness, improving the surface physical and mechanical properties, reducing the vibration of the bearing, agitation, improving the mission of the bearing, has an important role.

Analyses the 4 stages of the bearing superfinishing process:
(1) strong cutting stage. Workpiece surface rough spikes and oil stone surface contact, contact stress is very large, so that the abrasive grains broken self-sharpening, cutting role is strong.
(2) Normal cutting stage. After a few seconds. Workpiece rough layer is ground, that is, into the normal cutting stage, the surface of the oil stone has no black chips attached, but the cutting still continues.

(3) Grinding transition stage. The abrasive grain from the sharpness is reduced, the abrasive grain edge edge is smoothed, the chip oxides began to embed the oil stone void, the abrasive grain powder blocking the oil stone pore, so that the abrasive grain can only be weak cutting, accompanied by extrusion and the role of the research and polishing, the roughness of the surface of the workpiece will soon be reduced, the surface of the oil stone has a black chip oxides adherence.

(4) Stop cutting and grinding stage. Oil stone and workpiece mutual friction has been very smooth, the contact area increases greatly, the pressure decreases, the abrasive particles have been unable to penetrate the oil film and workpiece contact, when the supporting surface of the oil film pressure and oil stone pressure balance, the oil stone is floating. Between the formation of oil film, which is no longer cutting. This stage is unique to ultra-fine machining.

Super-fine bearings can be reflected in the following three aspects
1, can effectively reduce the degree of corrugation.
In the superfine research process, in order to ensure that the oil stone always acts on the wave peak and not in contact with the wave valley, the oil stone and the workpiece contact arc ≥ the wavelength of the workpiece surface corrugation, in this way, the wave peak of the contact pressure is larger, the peak is excised, so as to reduce the degree of corrugation.
2、Improve the groove shape error of ball bearing raceway.
The super fine grinding can effectively improve the groove shape error of about 30% of the raceway.
3、It can make the surface of the super fine grinding produce compressive stress.
In the process of superfine research, the main cold plastic deformation, so that after superfine research, the surface of the workpiece to form residual compressive stress.
4、It can increase the contact area of the working surface of the collar.
After ultra-precision grinding, the contact support area of the working surface of the collar can be increased from 15% to 40% after grinding to 80% to 95%.

First:Factors affecting capacity of slewing ring bearing

1. Structural design

The structural design of slewing ring bearing directly affects its bearing capacity. Designers need to consider factors such as the material, size, shape and type of slewing bearing to ensure that it can withstand the required load.

2, material strength

Slewbacks are usually made of high-strength metal materials, such as steel. The strength of the material determines the compressive and bending capacity of the slewing ring bearing, which affects its bearing capacity.

3, slewing ring bearing type

Slewing supports usually contain a bearing system inside to reduce friction and support rotation. The type and quality of the slewing ring bearing are directly related to the bearing capacity of the slewing bearing. Common bearing types include rolling bearings and plain bearings.

4. Working environment

The bearing capacity of the slewing bearing is also affected by the working environment. For example, if the slewing bearing is operating in high temperatures or harsh chemical environments, the corrosion and heat resistance of the material becomes a key factor.

slewing bearing Alt.

Second, the method of improving the bearing capacity of the slewing bearing

1. Optimize support structure design

To improve the bearing capacity of the slewing ring bearing, it is necessary to select the bearing with good quality. Secondly, it is necessary to optimize the structural design of the support to improve its bearing capacity. For example, strengthening the contact between the steel ball and the circular raceway in the contact area of the support and increasing the bearing area of the support can effectively improve the bearing capacity of the support.

2. Correct use and maintenance

In addition, the correct use and maintenance of the support is also the key to improve its carrying capacity. Regular inspection and maintenance to ensure the normal operation of the support, can be effective service life.

The factors that affect the bearing capacity of slewing ring bearings are usually tested and evaluated by manufacturers during the design and manufacturing process. When using a slewing bearing, it must be ensured that the load applied does not exceed its carrying capacity to avoid damage or accidents. The specific bearing capacity parameters can usually be found in the technical specifications of the slewing bearing product or the manufacturer’s technical data.

high precision cylindrical roller bearing

The method and advantage of artificial cleaning cylindrical rolling bearing

During the use of cylindrical roller bearings, many substances that reduce the life of the cylindrical roller bearings will be attached. Timing cleaning can increase the life of the cylindrical roller bearings. When artificial cleaning, it is only suitable for small bearing cleaning.

roller bearing Alt.

Artificial cleaning often takes the following methods alone or united:

1. Use hair brush, cotton wire and other tools to directly clean up the stolen goods on the cylindrical roller bearings.

2. Rinse the bearings, spray, or hold the cylindrical roller bearings in the cleaning solution with the shampoo, and motion the bearings to rotate at the same time. This is based on the power of the relative motion between the bearing parts and the liquid on the basis of soaking, and washed away the objects attached to the bearings.

3. Use hot oil, hot water, hot air, and steam to heat the cross roller bearings to dissolve and fall off by lubricating fat.

4. Soak the bearings with a certain liquid medium. The effect is mainly to separate the lubricating fat from the bearings, so that the stolen goods are cleared with the lubricant.

The commonly used mediums are solvents and weak alkaline liquids. Commonly used solvents are kerosene or diesel, because they have a certain decontamination ability and weak volatility. Compared to gasoline, acetone, benzene and other flammable and explosive toxic media are safer. Commonly used weak alkaline liquids include sodium carbonate aqueous solution and some synthetic detergent solutions.

Its main function is to remove lubricants on the bearing through saponification reactions. The cleaning medium should not cause adverse reactions such as corrosion of the bearings. The advantage of artificial cleaning is that there is no need for complex equipment and technology, and less investment.

The disadvantages of artificial cleaning are poor labor conditions, low efficiency, and the quality of cleaning are affected by the factors of the operator. When the roller bearing weight and size are large, it is difficult to clean it. At this time, mechanical cleaning is needed. The cleaning of the bearings is particularly important. Timing cleaning roller bearings can greatly increase the service life of the bearing。

high speed ball slewing ring bearing in stock

1.How to reduce slewing ring bearing tooth noise?

The slewing bearing can stably support the equipment for slewing motion, also known as the turntable bearing. The mechanical equipment needs to rotate without the transmission. The slewing bearing can be made of external teeth or internal teeth, and the rotation of the slewing bearing is realized through the gear transmission.

In practical applications, the force of the slewing bearing is different, the speed of rotation is also different, and the teeth of the slewing bearing are also different. In the process of gear transmission, the contact between the gear and the ring gear of the slewing ring will generate noise, so how to reduce the noise of the slewing ring?

slewing ring bearing Alt.

1. Control the tooth precision. Through long-term practice, we found that if we want to reduce the tooth noise, the tooth precision needs to be controlled at 7-8 grades. The higher the rotational speed, the higher the gear tooth precision requirements. Gear, tooth accuracy should be controlled within 7 grades.

2. Reduce the start-stop or forward and reverse frequency of the gear. Frequent start-stop or forward and reverse rotation will cause the gear to vibrate too fast, and the vibration will generate noise. The faster the vibration, the greater the noise. Reduce the start-stop or forward and reverse frequency, you can Reduce noise.

3. Reduce the impact load. The impact load will make the vibration frequency and torsion direction of the gear different, which will cause vibration in the circumferential direction, which will form a smooth noise. Reducing the impact load can reduce the noise.

4. Reduce the occurrence of resonance, which will generate high-frequency noise. When the motor rotates at a low speed or at a certain speed, the equipment will resonate, causing the gear and ring gear to oscillate at a high frequency and the two oscillating objects will contact. High-frequency noise will be generated, which can generally be reduced by changing the speed or adjusting the position of the equipment.

5. Increase the roughness of the tooth surface. If the roughness of the tooth surface is very poor, it will cause point contact on the tooth surface, and noise will be generated when the high point contact is made. If the roughness of the tooth surface is increased, the tooth surface will be in line contact, and the noise will be very high. Small.

6. Increase the lubrication of the tooth surface. Insufficient lubrication will lead to increased friction, and noise will be generated when the tooth surface is rubbed. Sufficient lubrication can reduce friction and effectively reduce noise.
