Abstract

The invention discloses an experimental platform for measuring the contact temperature of a gear tooth surface, which belongs to the field of mechanical engineering. The experimental platform comprises a test bench base, a main control cabinet, a gear box, a transmission belt protection cover, a drive motor, a drive shaft system, a driven shaft system, an electric brake device and a transmission belt. The gearbox comprises a drive gear and three displacement driven gears. Under the drive of the drive motor, the temperature of the working gear tooth surface under different working conditions can be monitored in real time by temperature sensors arranged inside gear teeth of the displacement driven gears. According to the invention, the experimental platform can effectively reflect the variation law of the tooth surface contact temperature of the gears during an actual transmission process; and an experimental support is provided for solving the problems of gear tooth deformation caused by the tooth surface temperature change, rigidity change, tooth surface gluing and the like during the gear transmission process.
