WSBC Excavator Bearings


Excavator bearings include: excavator travel bearings, excavator slewing bearings, excavator needle bearings, excavator gearbox bearings, excavator travel motor bearings, excavator travel drive bearings, excavator articulated bearings, excavator slewing bearing and Inch non-standard bearings used on the excavator.


Introduction Editor

The installation and disassembly method of the excavator bearing should be determined according to the structure, size and matching nature of the excavator bearing. The installation and disassembly pressure should be directly applied to the end face of the tightly matched excavator bearing ring, and the pressure cannot be transmitted through the excavator bearing rolling body, because this will cause indentation on the working surface of the excavator bearing, which will affect the normal operation of the excavator bearing It can even damage the excavator bearings. Parts such as the cage, seal ring, and dust cover of the excavator bearing are easily deformed, and the pressure to install or remove the excavator bearing cannot be applied to these parts.


Excavator bearing installation: edit

(1) Improper adjustment of the shifting device. If the transmission of this type of excavator adopts a mechanical manual shifting method, if the shift lever, vertical axis, horizontal axis and vertical fixing screws are loose, the transmission may "jump". Variable speed transmission mechanism wear

(2) Sudden change in external load   Due to the working nature of the excavator and the Excavator bearings

Due to the design of the body, sudden changes in the external load will also cause its transmission to "jump". When the road surface is uneven, the excavator is driving downhill, or the driving route is improper, the external load suddenly changes. This sudden change of load will act on the gear meshing gear of the transmission through the wheel and the transmission shaft to make the gear mesh. The gear is disengaged due to the axial thrust, causing the transmission to "jump". The performance of the self-locking mechanism decreases

(3) The transmission mechanism of the shifting device of the excavator relies on the sliding gear sleeve to move axially on the fixed gear sleeve and mesh with the driven gears of each gear to realize the gear shift. During frequent gear shifts, the end faces of the gear teeth of the above-mentioned meshing gears are easily ground into a tapered shape, resulting in a decrease in meshing performance and resulting in "jumping".

(4) In order to prevent the transmission from "jumping", the excavator has a self-locking function in the box cover hole above the transmission's Ⅱ, Ⅲ gear and Ⅳ, Ⅴ gear fork shaft and in the Ⅰ and reverse gear forks Steel ball and spring. When the elasticity of the self-locking spring is weakened or broken, the self-locking performance of the self-locking mechanism will decrease until it disappears, causing the transmission to "jump". At the same time, if the groove on the positioning steel ball or the fork shaft is worn, it can also cause the transmission to "jump".

(5) Improper operation method When the excavator is driving on a slope (especially when driving downhill), improper operation will also cause the transmission to "jump".
