摘要： The present invention relates to a motor structure, which has a shaft tube and a stator set disposed on a base. The shaft tube is in form of a circular tube, the bottom side thereof is in an integrally-formed and closed pattern, and an abrasive gasket, a limit member and a bearing are disposed in the shaft tube, such that a spindle of a rotor can be inserted in the bearing and rotate therein. As the limit member has an annular wall with a specific height, a plurality of limit protrusions extended inward from the inner wall of the through hole can snap a reduced neck of the spindle to limit its axial displacement, thereby attaining the design object of reserving enough space for accommodating an end section of the spindle, reducing necessary parts, assembling process, and saving production cost.

摘要： In order to be able to completely eliminate the axial play of an armature spindle of an electric motor, especially for a windshield wiping system of a motor vehicle, even though conditions change over time, a prestressing member acted upon by a spring leg continuously presses against the end of the armature spindle. The prestressing member does not necessarily have to abut directly on the end of the armature spindle, but rather a cap is inserted onto the end of the armature spindle and non-rotatably fixed to the motor housing or a gear housing. An eccentric formed as the housing of the prestressing member abuts on the outside of the bottom of the cap. In an alternative embodiment, a mushroom shaped prestressing member having a mushroom head presses against the end of the armature spindle. The axial feed movement results from a rotational movement caused by the spring in connection with at least one helical surface on the prestressing member which cooperates with a helical counter surface of the housing with each stroke in the turning direction.

摘要： An electric motor actuator (10) has an armature shaft (18) with a damper (28) comprising a collar (30) fit tightly into a housing (14) and slid over the shaft (18). The damper (28) has a plurality of spring-like fingers (32) protruding from the collar (30) supporting tghe shaft (18) intermediate to its journaled extreme ends (24, 26) by exerting sufficient force to damp vibrations caused by rotation of the shaft and counter-act the tendency of the shaft to move radially. The damper (28) is formed of a resilient, self-lubricating material impervious to grease, so as to isolate electrical motor parts from greased gears driven by the armature shaft.

摘要： An electric motor drive unit for driving a worm wheel such as for vehicle window regulator applications wherein a casing housing a rotatable armature utilizes a synthetic plastic end cap at one end, and a worm wheel housing constitutes the motor end cap at the other end. A worm shaft rotatably mounted within the wheel housing upon its own radial and thrust bearings interconnects to the motor armature through a self-aligning drive element extending through a thrust bearing defined in the worm wheel housing. The brush holders for the motor are homogeneously formed of synthetic plastic material upon the associated end cap, and the armature utilizes an inexpensive self-aligning bearing mounted within the end cap and worm wheel housing.

摘要： The invention is directed to a bearing arrangement for the shaft of the armature of an electric motor disposed in a support frame and subject to axial thrust. The bearing arrangement includes a bearing housing disposed so as to receive an end portion of the shaft therein and defining a bearing wall for receiving the axial thrust of the shaft. The bearing housing has a structure formed thereon for mounting the bearing housing to the support frame. A bearing at the interface of the bearing wall and the end portion transmits the axial thrust of the shaft to the bearing wall. A shaft bearing rotatably engages the end portion of the shaft and elastic material interposed between the structure and the support frame deforms elastically in response to the axial thrust applied to the bearing wall. The mounting structure is located with respect to the shaft axially back of the end of the end portion and the bearing wall is disposed axially beyond the mounting structure and the end portion so that the axial thrust of the shaft against the bearing wall will cause the bearing housing to center itself with respect to the axial thrust thereby taking up misalignment of the shaft relative to the shaft bearing.
