ABSTRACT:
Systems and methods for automatic belt tensioning in low speed, low volume fluid recovery. A required amount of tension is maintained across the recovery system's belt driven components under changing torque loads and operating speeds. This is accomplished by adjusting the distance between a motor output and a speed reducer input in response to a change in torque load between the motor and speed reducer. The required amount of tension is further achieved by adjusting the distance between an output of the speed reducer and a crank wheel in response to a change in torque load between the speed reducer and crank wheel.
