Furthermore, a positioning lug is further arranged on the left boss, and a positioning groove is correspondingly formed in the oil storage slot.
Furthermore, 3 mounting holes are correspondingly formed in the baffle and the idle gear shaft, two of the 3 mounting holes are tightening through holes, and one of the mounting holes is a threaded hole.
Furthermore, a through hole is formed in the central axial direction of the supporting seat shaft lever and used for connection and fixation. Furthermore, 3 mounting holes are distributed in a staggered manner; the radius of a journal of the idle gear shaft is 24 cm; when the left mounting hole is positioned in a horizontal direction, the horizontal distance between the center of the mounting hole and the center of the idler gear shaft is 16.5 cm; the vertical distance between the center of the mounting hole at the lower part and the circle center of the idle gear shaft is 16cm, and the horizontal distance is 4 cm; the vertical distance between the center of the mounting hole on the right side and the circle center of the idler gear shaft is 8.5cm, and the horizontal distance is 14 cm.
Further, the pressing plate and the idle gear shaft are integrally formed.
Compared with the prior art, the invention has the beneficial effects that: the invention can realize effective lubrication and has good stability. Meanwhile, when the idler gear is disassembled and assembled, only the idler gear shaft needs to be disassembled, and the idler gear seat can be installed on the machine body, compared with the traditional design, the disassembling and assembling space can be reduced by more than half, the operation is simpler and more convenient, and the reliability is good. Be equipped with 3 the mounting hole is for the distribution of phase error, can effectively prevent the misloading, and simultaneously, layout proportion scientific and reasonable can effectively improve the stability of whole part operation, excellent in use effect.
