ABSTRACT:
An assembly for maintaining tension in a drive belt features a housing mounted on a base. The housing contains a biasing element that exerts torque on the housing to bias the housing in a radial direction. A lever arm is connected to the housing and rotates with the housing in response to the bias of the biasing element. A pulley is connected to the lever arm and engages a drive belt in response to the bias force of the biasing element on the lever arm. The pulley deflects the shape of the belt to provide tension in the belt. In one embodiment, the apparatus allows the user to switch the position of the biasing element and alter the direction of torque on the lever arm. In another embodiment, the lever arm and pulley are removable from the housing and replaceable with other arms and pulleys having different configurations.
