Introduction of Excavator Bearing

The installation and disassembly method of excavator bearing should be based on the structure of excavator bearing, size, and the nature of the excavator bearing parts. The installation and disassembly pressure should be directly applied to the end face of the closely matched excavator bearing ring. The pressure can not be transmitted through the excavator bearing roller, as this will cause indentation on the working surface of the excavator bearing, the influence excavator bearing normal work even can cause the excavator bearing damage. The Cage, seal ring, dustproof cover, and other parts of the excavator bearing are easily deformed. The pressure of installing or disassembling the excavator bearing can not be put on these parts.

Application of special angular contact ball bearing in an excavator. This angular contact ball bearing has a larger contact angle (40 degrees), so it can bear a larger axial load and axial combined radial load. And it can carry a heavier load than a bearing of the same size because there are more balls in it. It is widely used in all imported excavators. Bearings of high accuracy, low noise, long life, and this kink are widely used in excavators. Mainly used in God steel excavators, Komatsu excavators, crawler excavators, Kato excavators, Hitachi excavators, Daewoo excavators, modern excavators, Volvo excavators, etc.

Excavator bearing is our common bearings, the quality of direct impact on the life of excavator bearing, while the material is also a direct factor affecting the excavator bearing failure.

Under the normal working condition, the normal operation of the excavator bearing also has the factor to cause the excavator bearing to fail in advance, the excavator bearing failure has many reasons, all the factors affecting the design and manufacture process are related to the bearing failure, which is difficult to judge by analysis.

The use factor mainly refers to the installation adjustment, the use maintenance, the maintenance repair, and so on whether conforms to the technical request. The installation condition is one of the most important factors in use. The improper installation of the excavator bearings often causes the stress state of the whole excavator bearing components to change, excavator bearings in the normal state of operation, and early failure.

Excavator Main Bearings

Excavator bearings include Excavator walking bearing, excavator rotating bearing, excavator needle bearing, excavator gearbox bearing, excavator walking motor bearing, excavator walking drive bearing, excavator joint bearing, slewing support bearings for excavators, and inch non-standard bearings for excavators.

Excavator Bearing Installation

(1) improper adjustment of gear shifting device. If the transmission of the excavator adopts mechanical manual shift mode, if the transmission lever, longitudinal axis, horizontal axis, and vertical fixing screw are loosened, the transmission may “Jump”. Wear of transmission mechanism

(2) the sudden change of the external load, because of the working nature of the excavator and the design reason of the excavator itself, the sudden change of the external load will also cause the transmission to “Jump”. When the road surface is uneven, the excavator drives downhill or the outside load changes suddenly due to improper driving route, this kind of sudden change of load can act on the gear of the transmission through the wheel and the transmission shaft, and cause the gear of the transmission to break off because of the axial thrust, causing the transmission to “Jump”. Performance degradation of self-locking mechanism

(3) the transmission mechanism of the gear-shifting device of the excavator realizes gear-shifting by means of the sliding gear sleeve moving axially on the fixed gear sleeve and engaging with the driven gears of each gear. In the process of frequent gear shifting, the tooth surfaces of the above-mentioned meshing gears are easy to be ground into a conical shape, which results in the reduction of meshing performance and “Gear jumping”.

(4) in order to prevent the transmission of “Jump gears”, the excavator has installed self-locking steel balls and springs in the box to cover holes above the II, III, IV, and V shift fork shafts of the transmission, and in the I and reverse shift forks. The self-locking performance of the self-locking mechanism will decrease until it disappears when the spring of the self-locking mechanism weakens or breaks, resulting in the transmission of “Jump gears”. At the same time, if wear occurs in the groove on the locating ball or the shifting fork shaft, it may also cause the transmission to “Jump gears”.

(5) the operation method is improper, when the excavator is running on the ramp (especially on the downhill), if the operation is improper, it will also cause the transmission of “Jump gears”.
