Abstract
An apparatus and method for effectively minimizing sound emanation from a power transmission belt drive and providing extended useful life of the power transmission belt by reducing the operating temperature thereof. In the illustrated embodiment, the drive system is enclosed in a housing having one or more inlets and one or more outlets. Air moving structure is provided in association with the pulleys for causing air flow through the interior of the housing from the inlets to the outlets as an incident of operation of the drive system. In the illustrated embodiment, the pulleys are formed of heat conducting material so as to transfer heat from the belt to the air being flowed through the interior of the housing, thereby reducing the operating temperature of the belt. A sound absorber may be provided within the housing and, in the illustrated embodiment, sound absorbing means are provided on the inner surfaces of the housing, the inlets and outlets, and may be provided internally of conduits which may be coupled to the inlets and outlets as desired. Fans may be provided in the inlet and/or outlet for augmented air flow through the housing.
