Manufacturing and Preparatory Experiment of Plastic Worm Gear Test Machine

Abstract

This paper describes the development of a plastic worm gear test machine and the preparatory experimental results. The test machine for plastic worm gears was newly developed, in which the center distance and shaft angle are variable and the transmission efficiency can be measured. Preparatory experiments were carried out using a commercial steel worm and plastic helical gears (worm wheel) under various running conditions. The effects of torques and rotational speeds on the gear teeth temperatures and transmission efficiencies between meshing gear teeth were determined.
