1. An apparatus for testing power transmission belts comprising:
- (a) at least one drive motor having a drive pulley mounted on its motor shaft, said drive motor having a synchronous speed,(b) at least one driven motor having a driven pulley mounted on its motor shaft, said driven motor having a synchronous speed,(c) means for applying an excitation voltage to said drive and driven motors,(d) a transformer connected to at least one of said drive motor and driven motor for controlling the excitation voltage applied to the motor to which it is connected, and(e) at least one test belt mounted between said drive and driven pulleys, the pitch diameters of said drive and driven pulleys being selected so as to rotate said drive motor at a speed lower than its synchronous speed and to rotate said driven motor at a speed higher than its synchronous speed whereby belt characteristics can be evaluated by inspection of the belt.

Abstract
An apparatus for testing power transmission belts is disclosed, wherein at least one test belt is mounted between at least one drive and driven motors each having corresponding numbers of drive and driven pulleys, respectively. The pitch diameter of the drive pulley is larger than that of the driven pulley to generate electric power in the driven motor. The test belt is subject to various loads due to torque variation of both drive and driven motors or either one of the motors by connecting a transformer to both or either one of the motors.
