Load carrying capacity of the crossed helical gears is considered to be low since the theoretical meshing is of a point contact. However, there is a possibility that a comparatively strong power can be transmitted because the contact area is widened by the elastic deformation and wear of gear teeth. In this study, the load carrying characteristics of the plastic (polyacetal co-polymer) crossed helical gears were investigated. The endurance tests for the plastic crossed helical gears of helix angle of 20 degrees were performed with the angle between shafts of 40 degrees and a rotational speed of 500rpm (about 1m/s in tangential speed). Temperatures of meshing teeth and atmospheric temperature were measured during operation and the fatigue life of gear teeth was determined. As a result, the relation between the life of gears and temperature of meshing teeth was clarified. And the relation between temperature rise from atmospheric temperature of meshing teeth and load torque was clarified.
