ABSTRACT:
A belt drive system in a washing machine for bidirectional operation in selection of agitation and spin cycles and having a belt and pulley arrangement adapted to transmit full motor torque in the agitation direction and substantially limited torque through belt slippage in the spin direction whereby final spin speed is reduced in proportion to out-of-balance conditions existing in the spin tub. A motor drive pulley having heat barrier means is provided to isolate friction heat generated by belt slippage on the pulley rim from the motor shaft and to prevent damage to elements in engagement with the shaft. A method of calibrating a belt tensioning spring is also disclosed.
