An electric motor mounting arrangement is disclosed which permits the motor to "float" within a blower housing without requiring any direct contact between the housing and the casing of the motor. This is possible because of the employment of a rubber-like gasket that supports the motor within the housing, so that only the flexible gasket makes contact with the motor. This unique gasket also provides an air space to permit air flow around the motor for heat ventilation, due to a plurality of ribs, nodes or bumps that create the air space, and in one environment, due partially to a series of aligned air slots in both the gasket and in the blower housing. The gasket together with a design configuration including spacing means prevents both halves of the motor housing from touching the motor casing, or each other, except thru a selectively dimensioned spacing means.
A non-metallic compressible gasket for insertion between a motor and a motor mount to permit the motor to float in a controlled range in said motor mount, comprising a flexible membrane having a body and a plurality of raised projections on the side of said gasket abutting said motor and spaces between said raised projections defining air flow passages between said motor and said projections, and a plurality of air slots aligned in both said gasket and said motor mount to permit air passage from the atmosphere through said motor mount and through said gasket and between said gasket and said motor back to the atmosphere to provide a heat ventilation airflow for said motor.
A gasket in use between a motor mount and a motor to permit air ventilation, heat dissipation, and noise and vibration isolation, comprising in combination:
A gasket and a motor mount as in claim 13, wherein air flow slots are provided in an aligned relationship in each of the housings and each of the gaskets.
A motor mount for receiving a gasket comprising a separable housing, each of which includes at least one recess well defining a locking hole to receive at least one gasket having a locking ring and nipple projecting from the side of the gasket adjacent said housing, and wherein the length of said nipple projecting through said locking hole is sufficient to provide a hand grip to permit said nipple and locking ring to be manually pulled through said hole and locked on the back side of said housing to hold said gasket securely in place.
