Description

Technical Field

[0001] This invention relates to the field of grinding wheel technology, and more particularly to an internal gear grinding wheel for a shaped grinding wheel. Background Technology

[0002] A gear grinding machine is a metal cutting machine tool used for the precision machining of gears. It uses a grinding wheel as a cutting tool to grind the already machined gear teeth, improving gear accuracy and surface finish; this machining method is called "gear grinding." It is suitable for precision machining gears made of steel with high hardness after quenching. It employs either the generating method, using a large flat grinding wheel or two specially shaped grinding wheels; or the forming method, using shaped grinding wheels to grind the gear teeth.

[0003] Existing gear grinding machines typically use bolts to fix the internal gear components when grinding internal gears. However, this fixing method is time-consuming and labor-intensive during installation and disassembly, reducing the efficiency of internal gear grinding. In addition, some internal gear components do not have mounting holes, making it impossible to fix them with bolts. Therefore, it cannot meet the requirements of internal gear grinding.

[0004] Therefore, we propose an internal gear grinding tool for a shaped grinding wheel gear grinding machine. Summary of the Invention
