Problems solved by technology

When the slewing mechanism is working, due to the large tangential force and radial force, the mechanism will produce a certain elastic deformation, so that the axis of the slewing reducer and the output gear will have a certain inclination. At this time, if the non-modified gear, the meshing spots of the output gear and the ring gear will be concentrated on the upper end of the output gear, resulting in abnormal meshing
At this time, if the tooth direction of the output gear is modified into an inverted bevel gear with a small tooth thickness at the upper end and a large tooth thickness at the lower end, the above problems can be solved. The inverted bevel gear is a cylindrical gear with special modification to the tooth direction of the gear. , it is mainly used for the output gear of the slewing mechanism with large output torque, and the inverted bevel gear is widely used in the slewing mechanism, so the inverted bevel gear is an important mechanical component; while the existing inverted bevel gear The processing of gears generally uses special equipment, and the existing hobbing machine does not have the function of processing inverted bevel gears. The hobbing machine needs to be modified, but the modification cost is high, and each gear is only hobbed with special equipment. The cost reaches more than 600 yuan, and the production cost is high, thus causing the high cost of the inverted bevel gear

Abstract

The invention discloses a processing method using a single-sided hobbing inverse bevel gear of a hobbing machine. The method comprises the following steps of: calculating a divided teeth change gear, a feeding change gear and differential change gears, wherein the feeding change gear: i1 = (625*f) / (288*phi), the divided teeth change gear: i2 = 24 / (Z+1 / 25), the differential change gears I: i3 = [(-9*sine beta) / m] - [625* delta Z] / (32*i1), and the differential change gears II: i4 = [(+9*sine beta) / m] - [625* delta Z] / (32*i1); selecting a gear hob, the modulus m of which is equal to the modulus m of an involute cylindrical gear according to a double-sided processing method by using the hobbing machine, selecting the divided teeth change gear according to the i2 = 24 / (Z+1 / 25), selecting the feeding change gear according to the i1 = (625*f) / (288*phi), and adjusting the hobbing machine according to a method for processing a straight toothed cylindrical gear; selecting one group of differential change gears I according to a single-sided processing method and the i3 = [(-9*sine beta) / m] - [625* delta Z] / (32*i1) for processing, and selecting the other group of differential change gears II according to the i4 = [(+9*sine beta) / m] - [625* delta Z] / (32*i1) for processing on the other gear surface of the straight toothed cylindrical gear. Therefore, the method solves the problem that the hobbing machine cannot process inverse conical teeth, improves the processing efficiency of the inverse bevel gear, and reduces the cost of the inverse bevel gear.

Description

Technical field [0001] The invention relates to a processing method for single-sided hobbing and cutting of inverted bevel gears with a gear hobbing machine, in particular to a processing method for using a gear hobbing machine for single-sided hobbing and cutting of inverted bevel gears suitable for large gears. 2. Background technology [0002] The slewing mechanism is a reducer driven by a hydraulic motor or an electric motor. It is fixed on the worktable, and the worktable is fixed on the rotatable support ring of the slewing support. ) ring gear is connected, and the output gear of the slewing mechanism meshes with the inner (outer) ring gear of the slewing support fixed on the frame. When the hydraulic motor or electric motor drives the reducer to rotate, its output gear meshes with the inner (outer) ring gear of the slewing support. Since the inner (outer) ring gear of the slewing support is fixed on the frame, the rotary The mechanism and the table rotate around ...
