Worm wheels are usually made from copper alloys. The use of stronger materials, such as cast iron, can improve cost efficiency and power density, but increases the risk of scuffing damage. In this work, a method to evaluate the scuffing load capacity of worm gear drives is developed. For this purpose, experimental tests are conducted to define a procedure for a scuffing test. Within theoretical investigations, a contact temperature simulation is developed and experimentally validated. The simulation is converted into an easily usable calculation method that can complement calculation methods of existing standards.
