Machining Technology of Rigid Flexible Wheel for Robot Reducer

Abstract

The invention discloses a processing technology of rigid flexible wheels of a robot speed reducer. The processing technology includes the steps of manufacturing blanks of the rigid flexible wheels byprecise casting or forging casting, subjecting the blanks of the rigid flexible wheels to rough processing, subjecting the rough-processed blanks of the rigid flexible wheels to heat treatment, subjecting external gears and internal races of the rigid flexible wheels to super-finishing, and detecting various index of the super-finished rigid flexible wheels until reaching requirements of finishedproducts.

Description

technical field [0001] The invention belongs to the technical field of robot reducer processing, and in particular relates to a processing technology for a rigid flexible wheel of a new robot reducer. Background technique [0002] At present, all similar products to robot reducers on the market cannot achieve high-precision integrated processing of external teeth and internal raceways, and are usually installed with finished bearings. [0003] However, the installation of finished bearings has great disadvantages: first, the matching size cannot be accurately controlled during installation, second, the cost is high, and third, the finished bearings are prone to damage when rotating at high speed, and the later maintenance period is short; [0004] Such as figure 1 and 2 As shown, the rigid flexspline 5 in the prior art is provided with rigid flexspline outer teeth i and through holes 3, and all current flexsplines similar to harmonic reducers are thin-walled gears, which a...

[0002] At present, all similar products to the robot reducer on the market cannot realize the integrated processing of high-precision external teeth and internal raceways, and are usually installed with finished bearings

[0003] However, the installation of finished bearings has great disadvantages: first, the matching size cannot be accurately controlled during installation, second, the cost is high, and third, the finished bearings are prone to damage when rotating at high speed, and the later maintenance cycle is short;

[0004] like figure 1 and 2 As shown, the rigid flexspline 5 in the prior art is provided with rigid flexspline outer teeth i and through holes 3, and all current flexsplines similar to harmonic reducers are thin-walled gears, which are limited by their working principles. Usually the flexible spline rotates for a long time, which is prone to wear and even gear breakage, which is often the key to the failure of the entire reducer; from the perspective of lubrication conditions, the traditional lubrication uses grease lubrication, which cannot achieve lubricating oil lubrication, so that The lubricating effect and cooling effect of the reducer are not ideal
