Problems solved by technology

However, a disadvantage of the disclosed gear grinding tool is that the service life of the finishing zone will end earlier than the service life of the rough grinding zone
Thus, the gear grinding tool will likely not be able to achieve the desired level of machining accuracy because the finishing region has a finer grinding surface than the rough-grinding region and tends to wear faster than the rough-grinding region to become unusable
Furthermore, once the finishing area is worn, the rough grinding area that is still usable becomes useless, resulting in an overall shortened service life of the gear grinding tool

Abstract

The invention provides a gear grinding tool and a method of using the gear grinding tool.The gear grinding tool (10) comprises a helical tooth (72) with grinding faces (70, 71) on the surfaces thereof.According to the gear grinding tool (10), tooth flanks of gears (16) as workpieces are ground by the grinding faces (70, 71).The grinding face (70) comprises a rough grinding face (74) for performing a rough grinding process.The grinding face (71) comprises a rough grinding face (74) for performing a rough grinding process.The rough grinding face (74) comprises a forming line (76) for performinga fine finishining process.

Description

technical field [0001] The present invention relates to a gear grinding tool having helical teeth that engage a rotating gear to grind the gear. The invention also relates to a method of using such a gear grinding tool. Background technique [0002] Generally, a gear grinding machine includes a tool shaft, which holds a gear grinding tool having helical teeth, and a work shaft, which holds a gear used as a workpiece. During operation, the tool shaft and the workpiece shaft rotate synchronously with each other in order to grind the tooth flanks by the gear grinding tool. [0003] Such tooth flanks are usually ground separately in two stages, a rough grinding stage and a finishing stage. The rough grinding stage and the finishing stage respectively use rough grinding tools and finishing tools to continuously perform corresponding grinding processes on the tooth flanks in order to grind the tooth flanks to the desired finishing degree.
