Near-net shaping device for spiral bevel gear, manufacturing method of near-net shaping device and rolling assembly

Abstract

The invention discloses a near-net shaping device for a spiral bevel gear, a manufacturing method of the near-net shaping device and a rolling assembly. The rolling assembly comprises at least one rolling part and a rolling guiding mechanism. At least part of the peripheral edge of each rolling part is provided with spiral conical teeth, the rolling parts are connected to the rolling guiding mechanism in the manner that the rolling parts can roll around a circumference, and therefore when the rolling parts roll on the peripheral edge of a forming blank, after the spiral conical teeth on the rolling part roll the forming blank, the spiral conical teeth can roll out from spiral conical tooth grooves in the forming blank smoothly, and the problem that demolding of the spiral bevel gear is hard in the forming process is solved.

Description

technical field [0001] The invention relates to a spiral bevel gear forming equipment, in particular to a spiral bevel gear near-net forming equipment, a manufacturing method thereof and a rolling assembly. Background technique [0002] Spiral bevel gears have the advantages of large overlap coefficient, strong load capacity, high transmission ratio, stable transmission, and low noise. They are widely used in mechanical transmission fields such as automobiles, aviation, and mines. The meshing principle between the spiral bevel gears and the processing and forming theory of the spiral bevel teeth on the spiral bevel gears are extremely complicated, and are generally processed by special machine tools. The complete set of machining technology for spiral bevel gears on spiral bevel gears is basically monopolized by Gleason in the United States, Oerlikon in Switzerland and Klingelnberg in Germany, and must follow the "grid" system, " Design and process spiral bevel gears accord...

AI Technical Summary

Problems solved by technology

If this kind of equipment is used for the finishing of spiral bevel gears, since there is no spiral bevel teeth on the workpiece at the beginning, and the ring gear can only rotate around a fixed rotation axis, it is easy to slip between the ring gear and the workpiece. resulting in tooth disorder

In addition, this kind of finishing equipment requires that the workpiece needs to rotate with the rotation of the ring gear, so when the ring gear stops rotating, the workpiece may have a tendency to rotate in the axial direction, which will cause trouble for demoulding
