Title:
MOTOR SPEED REDUCER INTEGRATED HOUSING HAVING COOLING WATER CHANNEL
Document Type and Number:
WIPO Patent Application WO/2019/205694
Kind Code:
A1
Abstract:
A motor speed reducer integrated housing having a cooling water channel comprises a speed reducer housing (1) and a motor housing (2) integrated with the speed reducer housing (1). A cooling water circulation channel (3) is provided in the speed reducer housing (1) and the motor housing (2). The cooling water circulation channel (3) is used for cooling a stator core, a motor bearing seat (4), and an end surface of a front end cover mounted in the motor housing (2). The motor speed reducer integrated housing is integrally cast, and the cooling water circulation channel (3) is provided with an internal cavity by means of low pressure casting, and is used for cooling the motor stator core, the speed reducer housing (1), and the motor bearing seat (4), thereby improving cooling efficiency of an entire cooling system, reducing heat loss of an electric driving system, and extending the service life of bearings.
