Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 The strength of plastic greatly varies with temperature; that is, the strength increases as the temperature decreases. Therefore, the lifetime of a plastic gear can be increased by reducing the meshing-teeth temperature of the gear.
