In recent years, the demand for precision machining of planetary gears has increased due to the requirement of reduced noise and vibration in automotive transmissions. For ring gears (one of the components of the planetary gear system), the conventional method of finishing has been gear shaping or helical broaching followed by heat treatment. To meet the increasing requirement of the aforementioned demand, mass produced planetary gear systems, must be hard gear finished after heat treatment with high accuracy and efficiency. This paper presents a new gear grinding machine developed specifically for economical finish grinding of automotive internal ring gears in mass production.
