Abstract
The utility model relates to a pushrod motor which is characterized by comprising a housing. A motor is installed in the housing through a support. One end of a screw-nut is connected with an output shaft of the motor through a shaft coupling. The screw-nut is made of engineering plastics. An inner ring of a bearing sleeved on the screw-nut is embedded on the screw-nut by injection moulding. An outer ring of the bearing is arranged in a bearing pedestal of the housing. A pushrod comprises a shaft part and a screw rod part. The screw rod part of the pushrod is in threaded connection with the screw-nut. The shaft part of the pushrod passes through a shaft hole in the housing and extends out of the housing. The pushrod motor is simple in structure, adopts the screw-nut formed by injection moulding, arranges the inner ring of the bearing to be embedded on the screw-nut, reduces the number of components, improves reliability of connection between the bearing and the screw-nut, is convenient and fast in installation, improves production efficiency, reduces production cost, and prolongs the service life.
