Abstract:
A transmission includes a housing and a gear assembly supported by the housing. The gear assembly includes a shaft carried by the housing, a bull gear attached to the shaft, and a helical gear shaft carried by the housing. The helical gear shaft incorporates a helical gear operatively connected to the bull gear. The transmission can be either a single-speed transmission or a variable-speed transmission. The single speed transmission employs a pulley attached to the helical gear shaft, and a belt wrapped around the pulley. The variable-speed transmission employs a driven pulley supported by the helical gear shaft, an idler pulley pivotably attached to the housing, and a belt wrapped around the driven pulley and the idler pulley.
