The invention relates to a harvester part and specifically relates to a supporting wheel shaft of a harvester. The supporting wheel shaft comprises a supporting wheel connection section and a crossbeam connection section, wherein a supporting wheel is installed on the supporting wheel connection section, the crossbeam connection section is connected with a crossbeam, a shaft hole is formed in the crossbeam, the crossbeam connection section of the supporting wheel shaft is arranged in the shaft hole of the crossbeam in a penetration mode, and a thread is arranged at the outer end of the crossbeam connection section of the supporting wheel shaft. The supporting wheel shaft is characterized in that a ring-shaped flange is arranged at one end of the crossbeam connection section of the supporting wheel shaft, the end of the crossbeam connection section of the supporting wheel shaft is connected with the supporting wheel connection section of the supporting wheel shaft, the diameter of the crossbeam connection section of the supporting wheel shaft is smaller than that of the shaft hole of the crossbeam, and a thread end of the crossbeam connection section of the supporting wheel shaft and a nut are fixed through a gasket. According to the supporting wheel shaft of the harvester, the diameter of the crossbeam connection section of the supporting wheel shaft is smaller than that of the shaft hole of the crossbeam, so that the supporting wheel shaft can be conveniently maintained and replaced as desired.
Description
technical field [0001] The invention relates to parts for a harvester, in particular to a harvester supporting wheel shaft. Background technique [0002] In the prior art, the harvester roller shaft and the shaft hole of the girder adopt interference installation to prevent the roller shaft from shaking in the shaft hole of the girder and affect the use effect. [0003] However, the working environment of the harvester is relatively harsh, and the roller shafts are prone to rust and damage, and need to be replaced and repaired. However, the roller shafts and girders are installed with interference, which is very easy to rust, difficult to disassemble, and more troublesome to replace. Contents of the invention [0004] The purpose of the present invention is to provide a harvester roller shaft with stable operation and convenient maintenance and replacement. [0005] The technical solution to achieve the above purpose is: the harvester roller shaft, including the roller co...
