Excavator Bearing

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 bearings and in Inch non-standard bearings used on excavators.

The installation and disassembly method of the excavator bearing should be determined according to the structure, size and matching nature of the excavator bearing. Installation and disassembly pressure should be directly applied to the end face of the closely-fitting excavator bearing ring, and the pressure cannot be transmitted through the excavator bearing rolling elements, because this will produce dents on the working surface of the excavator bearing, which will cause impact The normal operation of the excavator bearing can even damage the excavator bearing. Parts such as cages, sealing rings and dust caps of excavator bearings are easily deformed, so the pressure of installing or disassembling the excavator bearings cannot be applied to these parts.

 

Excavator bearing installation:

(1) Improper adjustment of shifting device. If the transmission of this excavator adopts a mechanical manual shift method, if the gear lever, vertical shaft, horizontal shaft and vertical fixing screws are loose, the transmission may “jump”. Gearbox wear

(2) Due to the working characteristics of excavators and excavator bearings, the external load changes suddenly

 

Excavator Bearing

Due to the design of the car body, sudden changes in external load will also cause its transmission to “jump”. When the road is uneven, the excavator is driving downhill or the driving route is incorrect, the external load will suddenly change. This sudden change in load will act on the gear meshing gears of the transmission through the wheels and drive shafts, so that the gears mesh. The gears disengaged due to axial thrust, causing the gearbox to “jump”. Performance degradation of self-locking mechanism

(3) The transmission mechanism of the speed change device of the excavator relies on the sliding gear sleeve to move axially on the fixed gear sleeve and mesh with the driven gear of each gear to achieve speed change. During frequent gear shifts, the end faces of the teeth of the aforementioned meshing gears are easily ground into a cone shape, resulting in a decrease in meshing performance and “bounce”.

(4) In order to prevent the gearbox from “jumping”, the excavator has self-locking function balls and springs in the box cover holes above the gearboxes II, III and IV, V fork shafts, and I and reverse forks. When the elasticity of the self-locking spring is weakened or destroyed, the self-locking performance of the self-locking mechanism will be reduced until it disappears, causing the transmission device to “jump”. At the same time, if the positioning steel ball or the groove on the fork shaft is worn, it will also cause the gearbox to “jump”.

(5) Incorrect operation method When the excavator is driving on a slope (especially when driving down a slope), incorrect operation will also cause the gearbox to “jump”.
