との間の遊びが補償される。[Prior Art] According to WO 82/03735, in a swivel bearing for a generator, two bearing eyes are provided in front and behind one another in a casing of an electric machine, and both bearing eyes are provided. A bearing holder, which has a bearing hole and is integrally formed with the drive unit, engages between the two. The bearing pin, which is embodied as a screw, is pushed through the front bearing eye as well as the bearing hole of the bearing holder and screwed into the threaded bush provided in the rear bearing eye. The threaded bushing is then axially displaceable in the bearing eye, which compensates for the play between the bearing holder and the rear bearing eye on the brush side of the double pivot arm.

解離を生じるおそれがあることにある。The disadvantage of this configuration is that the threaded bush is loosely inserted into the bearing eye, which causes the threaded bush to be exposed to vibration and temperature loads over time, which results in poor bearing performance. It is stable and may cause dissociation of the bearing pin.

ならないからである。Furthermore, according to West German Patent Application Publication No. 2749196, it is known to eliminate the looseness of the nut on the bolt by frictional sitting of the nut, in which case the nut is provided with a vertical slit, The nut is slightly expanded when screwed in, so that the nut is fixedly tightened on the bolt. In that case, a lock ring additionally attached to the cylindrical additional part of the nut is adapted to prevent further rotation of the nut. However, this configuration cannot be used for swivel bearings for electric machines. This is because in this case the play between the double pivot arm and the bearing holder must be compensated.
［考案の課題］ 本考案の課題は旋回支承部のねじ付きブッシュが摩擦的
に、回動不能にかつ軸方向移動可能に旋回支承部の支承

時のねじ付きブッシュの滑落と紛失とが回避される。[Operation and effect of the present invention] The advantage of the present invention is that the threaded bushing is already inserted into the bearing eye when the electric machine is assembled, so that the swivel bearing can be fixedly seated even under vibration load and temperature load. It is guaranteed. Furthermore, the axial displacement ensures a defined abutment of the double swivel arm on the vehicle-side holder. It is easy to assemble and avoids slipping and loss of the threaded bush during assembly.

回動が効果的に阻止される。Another configuration of the present invention is described in claims 2 and below. In the case of a threaded bush, bearing pins with different thread lengths can be used. Furthermore, the front part of the threaded bush can be expanded to form a bearing bush for the insertion of bearing pins. Furthermore, a flange is provided in the front region of the threaded bush, which is expanded to form a bearing bush, and at the outside of the flange is provided at least two opposed flats, which flats correspond to each other. The engagement of the threaded bush in the recess formed in the bearing eye effectively prevents the threaded bush from rotating in the bearing eye.

Fixed to. The double swivel arm consists of two bearing eyes 12, 13 which are spaced one behind the other and which are formed integrally with the bearing shield 14 on the drive side and the bearing shield 15 on the brush side. ing. Holder 11 has bearing holes 16
In the area with the two bearing eyes 12, 13 engaged, in which case the bearing is formed as a screw and the bearing eye 1
2, 13 and a bearing pin 17 inserted in the bearing hole 16. The rear bearing eye 13 provided on the bearing shield 15 on the brush side is provided with an axially movable threaded bush 18 in which the threaded portion 19 of the bearing pin 17 is screwed. On the bearing shield 14 on the drive unit side, another bearing eye 20 is integrally formed on the side facing the front bearing eye 12 and a drive belt (not shown) is stretched by this bearing eye 20. After that, this generator is screwed to a support (not shown) of the automobile.

じ込みによっても強化される。For a simple and non-rotatable fixing of the threaded bush 18 in the rear bearing eye 13, the threaded bush 18 is provided with a longitudinal slit 21 therethrough. This threaded bush 18
When inserting into the bearing eye 13, the threaded bush is first compressed and then clamped in the bearing eye 13 by its elastic spreading force. In order to compensate for the axial play between the holder 11 and the bearing eyes 12, 13, the threaded bush 18 is axially displaceable against the expanding force that is effective when the bearing pin 17 is tightened. Threaded bush in bearing eye 13
The tightening of 18 can also be strengthened by screwing in the bearing pin 17 if the dimensions of the screw are appropriate.

Will be realized. As shown in FIG. 2, the threaded bushing 18 is provided with a flange 24 in the front region which is expanded to form a bearing bush 23, which flange has two flat portions lying opposite each other on its outside. twenty five
Is equipped with. This flange 24 has a recess 26 which is appropriately formed in the bearing eye 13 by its flat surface 25 to prevent rotation.
Engage in. The threaded bush 18 may be formed such that a hexagonal eccentric or similar asymmetrical portion is inserted into a suitable notch in the bearing eye 13 to prevent rotation.
