China Factory Wholesales Turntable Bearings

1.Comparison of the use of turntable bearings and geared slewing drives for truck-mounted cranes

Crane truck, referred to as crane (crane truck), is a hoisting mechanism installed on a cargo truck to achieve the purpose of loading or hoisting goods. The lifting mechanism can lift, retract and rotate, and can flexibly lift the goods and place them in the designated position.

The rotation of the hoisting mechanism is realized by the turntable bearing or the slewing drive. The above picture is a common hoisting mechanism with a slewing bearing installed. The outer tooth turntable bearing is equipped with a yellow protective cover to protect the operator and the equipment.

In the picture, near the slewing mechanism, the grease flows around and quickly loses, the equipment is dirty, and the grease is polluted and lost, resulting in frequent refilling of grease, high maintenance costs, and high equipment failure rate.

Straight-toothed rotary drive, also called geared rotary drive, is composed of turntable bearings, gears, housings, adapter flanges, support turntable bearings, seals and other components. A rotary speed reducer that bears axial force, radial force and overturning moment at the same time and has a certain reduction ratio, referred to as rotary drive.

The structure of the spur gear rotary drive determines that the spur gear drive has the characteristics of dustproof and waterproof, compact design, convenient installation and use, stable and reliable, and low failure rate.

During the use of the truck mounted crane with gear type rotary drive, the equipment is kept clean, brand new, with low failure rate, no loss of grease, not easy to be polluted, low maintenance frequency, stable operation and long life.
