Embodiment 1

[0092] Such as figure 1 The manufacturing method of the shown harmonic reducer 100 (model: 14-50) includes the following steps:

[0093] (1) Processing of flexible spline 1 and rigid spline 3

[0094] The processing procedure of the flexible wheel 1 is: lowering the bar - forging (forging the bar into a ring, and the initial temperature of the forging is 1150°C, and the end temperature is 850°C) - annealing - spinning (spinning the workpiece into a Thin-walled solid ring, and reserved machining allowance) - quenching and tempering (hardness control is HRC35) - rough turning - finishing turning - surface hardening (hardness control is HRC45) - sandblasting (only thin-walled parts) - Double end surface fine grinding (surface roughness is 0.4μm, surface parallelism is 1μm)-inner and outer circle fine grinding (surface roughness is 0.4μm)-screw hole machining-the first ultrasonic cleaning and drying-ultra-precision gear shaping ( The surface roughness is maintained at 0.4 μm) - ...

Abstract

The invention provides a manufacturing method of a bearing and a manufacturing method of a harmonic reducer. In the manufacturing method of the bearing, nano ceramic materials are adopted for machining of rolling balls or rolling columns, and vacuum graphite electroplating is carried out on the surface; machining of an inner ring and an outer ring comprises the steps that a rod is sequentially subjected to forge pressing, annealing, spinning, intermediate treatment, accurate grinding of the end face, the inner circle and the outer circle, accurate grinding and grinding of a bearing channel andaftertreatment; and then, assembling is carried out, the precision, stability and wear resistance of the bearing manufactured through the manufacturing method are greatly improved, temperature increase and weight are reduced, and the service life of the bearing is greatly prolonged. Meanwhile, after a flexible wheel and a rigid wheel of the harmonic reducer are forged and pressed, spinning is carried out, a product can have good toughness and is not prone to breaking, through combination with a series of treatment of accurate grinding of the end face, the inner circle and the outer circle andultrasonic treatment, the dimensional precision is improved, surface roughness is reduced, friction is reduced, and temperature increase is reduced. Thus, the harmonic reducer has high precision, long service life and high durability.

Description

technical field [0001] The invention relates to the technical field of harmonic reducers, in particular to a method for manufacturing a bearing used in a harmonic reducer and a method for manufacturing the harmonic reducer. Background technique [0002] Under the environment of the international intelligent manufacturing industry 4.0 and my country's intelligent manufacturing 2025, many countries are investing huge sums of money in the research and development of intelligent products. One of the products, and the harmonic reducer is one of the core key components of the robot. If you want to develop and manufacture high-precision and high-performance robots, you must first manufacture a high-quality harmonic reducer. [0003] The market demand for harmonic reducers in my country is huge. The research and development of the design technology and production technology of harmonic reducers has very important economic and social significance. At present, due to the lack of core t...
