The diameter of the secondary drive shaft, and the left side of the primary transmission axis is connect with the bevel gear ontology, the right axle
Portion further includes the conical round table for being connected to the right side of the secondary drive shaft, wherein the primary transmission axis is leaning on proximal ends
The left and right annular groove for installing bearing is respectively formed at portion.
Further, the left axle portion and right axle portion of the transmission shaft and the junction of the bevel gear ontology are formed with circular arc
Chamfering.
Further, the junction of the primary transmission axis and secondary drive shaft is formed with circular arc chamfering.
Further, the diameter of the circular arc chamfering is 5-10mm.
Further, the depth of left and right annular groove is 3-5mm.
Compared with prior art, have the following advantages and beneficial effects: the utility model has bearing to the utility model
The angular wheel shaft forging of mounting groove, in being formed in proximal ends portion there are two annular groove for primary transmission axis, the annular groove is passed through
It after crossing subsequent finishing is used to that bearing to be installed, improves the bearing strength of transmission shaft and guarantee rotating accuracy, described bearing or so
End face is connected to the medial surface of the annular groove, so that the process middle (center) bearing that effectively prevent running at high speed is axially moved, improves
The installation reliability of bearing.The angular wheel shaft forging structure with bearing mounting groove of the utility model is simple, easy to process, tool
There is very strong generalization.
