Processing method of thin-wall bearing for industrial robot

Abstract

The invention relates to a processing method of a thin-wall bearing for an industrial robot. Through technical innovation, deep research of the thin-wall bearing comprises a dynamic quality high-precision detection technology of the thin-wall bearing, a ferrule micro-deformation thermal treatment step, a grinding metamorphic layer-controlled bearing ring fine grinding process, a negative play precise control technology, a precise assembly technology, a ferrule inner and outer diameter non-contact measuring technology and a bearing comprehensive property test technology, so that the thin-wall bearing meets the production demand of think-wall bearing design. The processing method provided by the invention has the beneficial effects that a steel ball is assembled by way of pulling the outer ring and jacking the inner ring by virtue of an assembling tool, the quality and reliability of the thin-wall bearing and a whole harmonic speed reducer are greatly improved, and the deformation residual stress of the outer ring is reduced to the maximum due to the pulling and jacking process during assembly. The minimum deformation of the outer ring needed is formed when the steel ball is assembled and placed due to the process of puling the outer ring and jacking up the inner ring, so that the residual stress caused by assembly is greatly reduced, and the service life of a product is also effectively ensured.

Description

technical field [0001] The invention relates to the field of bearing processing, in particular to a processing method for thin-walled bearings used in industrial robots. Background technique [0002] The development direction of modern industrial robots tends to be lighter, which requires the supporting bearings to have a lighter structure. Since the bearing needs to meet the performance requirements of the industrial robot host on the bearing capacity, precision, stiffness and frictional moment in the limited installation space, it is difficult to meet this requirement by selecting standard general-purpose bearings, while thin-walled bearings pursue the limit size of the shape and have Light weight, small size, high precision, long life and other excellent properties can solve this problem well. [0003] Special bearings for industrial robots mainly include equal-section thin-walled bearings, thin-walled crossed cylindrical roller bearings, RV reducer bearings and harmonic...

Problems solved by technology

Most of the supporting bearings for domestic industrial robots rely on imports. Although a few manufacturers produce supporting bearings for industrial robots, they have small batches, few varieties and specifications, low degree of generalization of parts, long supply cycle, high cost, and unstable quality. Seriously restrict the normal development of the domestic industrial robot industry
