摘要

To improve tracking, an exercise treadmill is provided with a frame (12, 12') including molded plastic pulleys (22,28), having an integral gear belt sprocket (108), an endless belt (20) extending around the pulleys and a motor (104) operatively connected to the rear pulley to drive the belt (20). The pulleys (22,28) are molded out of plastic and have a diameter of approximately nine inches. A deck (50) underneath the running surface of the belt (20) is supported by resilient members (100,102,103). A positive lateral belt tracking mechanism (200,200') is used to correct the lateral position of the belt (20). A belt position sensor mechanism (210) is used in combination with a front pulley pivoting mechanism to maintain the belt (20) in the desired lateral position on the pulleys (22,28). The exercise treadmill also includes a lift mechanism with an internally threaded brass or steel sleeve engaged to vertically aligned nonrotating screws. A user display of foot impact force on the belt is also provided.
