Abstract

The invention provides a thrust wheel shaft, a thrust wheel and an operation machine. The thrust wheel shaft comprises an oil inlet, a first oil outlet, a second oil outlet and a lubricating oil channel. The oil inlet is formed near the middle part of the thrust wheel shaft and is used for communicating with a first oil storage cavity on a wheel body of the thrust wheel; the first oil outlet is formed in the first end close to the thrust wheel shaft and used for extending to a first floating oil seal on the thrust wheel. The second oil outlet is formed in the second end close to the thrust wheel shaft and is used for extending to a second floating oil seal on the thrust wheel; the lubricating oil channel is arranged in the supporting wheel shaft and extends from the first end of the supporting wheel shaft to the second end of the supporting wheel shaft, and the lubricating oil channel is communicated with the oil inlet, the first oil outlet and the second oil outlet. The lubricating environment of the floating oil seal of the thrust wheel is improved, the situation that the floating oil seal and a lining of the thrust wheel are excessively abraded due to the fact that the lubricating oil amount is reduced is prevented, and the service life of the thrust wheel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of operating machinery, in particular to a support wheel shaft, a support wheel and an operating machine. Background technique [0002] In working machinery, supporting rollers are widely used as chassis bearing parts of crawler excavators, cranes and other working machinery. Due to the large working load of the track rollers, and the working machinery often works in the environment with poor conditions such as muddy water and dust, impurities such as cement and dust can easily enter the track rollers, resulting in damage to the track rollers. Among them, the damage of the roller is mainly reflected in the oil leakage of the floating oil seal of the roller. [0003] Existing rollers usually include a wheel body and a roller shaft. The wheel body is rotatably sleeved on the roller shaft. Realize the communication of the cavities where the floating oil seals on the left and right sides of the rollers are loc...
