Grinding wheel assembly for small-modulus gear grinding and assembling method

Abstract

The invention belongs to the technical field of precision machining, and provides a grinding wheel assembly for small-modulus gear grinding and an assembling method to solve the grinding problem of small-modulus gears. The integrated structure of a grinding wheel cantilever frame and a built-in belt pulley is adopted, so that high installation and positioning precision and the compact structure are achieved; a bearing adopts a V-shaped positioning mode, so that disassembling and installation positioning are convenient; a plurality of evenly distributed threaded holes are formed in a locking nut in an integrated mode and used for adjusting the dynamic balance of a rotating part in the grinding wheel assembly, so that vibration reduction and noise reduction of the grinding wheel assembly areachieved, and the service life of a system is prolonged; and a U-shaped groove is formed in the shaft shoulder of a grinding wheel main shaft for transmission of an O-shaped belt, and the dustproof effect is achieved through the labyrinth sealing principle. The grinding wheel assembly has the advantages of being compact in structure, convenient to disassemble, high in positioning precision, convenient to operate and the like, grinding of small-modulus outer gears and inner gear rings is achieved, and good market application prospects and popularization value are realized.

Description

technical field [0001] The invention belongs to the technical field of precision machining, and relates to a grinding wheel assembly and an assembly method for grinding small modulus gears. Background technique [0002] Gear is a key mechanical transmission basic part with a large quantity and a wide range. Among all kinds of mechanical parts, its industry scale is the largest. The gear industry has two "extremes": one large and one small. Among them, the irreplaceability of the small modulus gear makes it a key part of precision machinery, electronic machinery, instrumentation, aviation equipment, timing mechanisms and other equipment. There are two types of high-end products in the small modulus gear industry, one is precision small modulus gears, and the other is precision transmission devices with precision small modulus gears as key components, such as harmonic reducers, which are mainly used in robots, numerical control Machine tools and other fields. However, at pre...

AI Technical Summary

Problems solved by technology

The grinding head in the commonly used grinding wheel grinding assembly is inconvenient to disassemble, and the related parts of the grinding wheel and the grinding head can be replaced by disassembling the grinding wheel cantilever frame, the process requirements are cumbersome, and the installation and positioning accuracy is difficult to guarantee

The existing grinding wheel grinding system still has problems such as poor dust resistance and easy vibration, which makes it difficult to meet the grinding needs of high-precision small modulus gears
