概要

Using a power circulating type gear testing machine for straight bevel gears, the dynamic load of gear teeth, the torque variation and the bending vibration of gear shaft are measured under a constant torque with the speed of gear varied, and the results are discussed. The results are as follows : According as the speed of gear increases, the dynamic load factor varies in accordance with the contact position on a tooth trace and the load. The dynamic load factor is influenced more at the toe or center of bevel gear tooth than at the heel by the torque variation and the bending vibration of gear shaft. And the torque variation and the bending vibration of gear shaft are influenced considerably by the torsional vibration at the natural frequency of meshing gear.
