Custom Gear Manufacturing Case Study: Grinding and Evaluation of Trochoidal Tooth Profiles for Precision Reducers

Ozig can perform grinding processing of trochoidal tooth shapes!

This is a case study of grinding processing for trochoidal tooth profiles used in industrial machinery. The tooth profile is required for precision indexing parts where backlash is a concern, and it is utilized in various fields, including robotics, aviation, and motors, in addition to industrial machinery. Since it is a special tooth profile, the request required specific demands for processing equipment, measuring instruments, and evaluation methods. The shape was different from the tooth profile designed by each machine manufacturer, so the customer provided the coordinates of the tooth profile shape, and we proceeded with grinding and evaluation. At our company, we utilized the latest gear grinding machines, such as the VIPER500W and P100L, to process gears of arbitrary shapes. When measuring arbitrary shapes, it is necessary to make contact with the measuring probe perpendicular to the coordinate points on the tooth surface. Therefore, it is essential to understand the required shape and ensure that the measuring equipment can maintain the appropriate measurement position. As a result, the evaluation by the customer was satisfactory, and we received high praise even for arbitrary tooth profiles that are not specified in standards.
