The purpose of the utility model is to provide a motor installation structure that prevents the upper end cover from loosening.

For this purpose, the utility model adopts the following technical solutions:

A motor installation structure, including a lower end cover, an upper end cover and a rotating shaft, the upper and lower end covers are fixedly connected by fastening bolts, one end of the rotating shaft is fixed on the upper end cover, and the other end extends through a bearing provided on the lower end cover To the outer side of the lower end cover, the lower end cover is provided with a mounting groove, the bearing is arranged in the mounting groove, the inner ring of the bearing is provided with extension parts on both sides, and the extension part is inserted with a connection for fixedly connecting the rotating shaft. pin, and a cover plate for sealing the bearing in the installation groove is fixed on the installation groove.

Further, the outer side of the lower end cover is provided with a fastening bolt groove, the bottom of the fastening bolt groove is provided with a connecting through hole, the connecting surface of the upper end cover and the lower end cover is provided with a threaded hole, and the fastening bolt is arranged on the fastening bolt. In the bolt groove, and pass through the connecting through hole and the threaded hole to connect the upper and lower end covers.

Further, the cover plate is fixed on the lower end cover by screws.

The beneficial effect of the utility model is: the rotating shaft of the motor is connected with the bearing through the connecting pin, the bearing is fixed in the installation groove of the lower end cover through the cover plate, the rotating shaft, the bearing and the lower end cover are fixed into one, and the axial force is transmitted to the lower end The cover reduces the stress on the fastening bolts, reduces the occurrence of loosening of the fastening bolts, and ensures the normal use of the motor.

Description of drawings

Fig. 1 is a cross-sectional view of a motor installation structure provided by a specific embodiment of the present invention.

In the figure, 1. Upper end cover; 2. Lower end cover; 21. Fastening bolt groove; 22. Connection through hole; 3. Fastening bolt; 4. Rotating shaft; 5. Bearing; 51. Extension part; 6. Connecting pin; 7. Cover plate; 8. Screws.

Detailed ways

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

As shown in Figure 1, the motor installation structure includes a lower end cover 2, an upper end cover 1 and a rotating shaft, the upper and lower end covers 1, 2 are fixedly connected by fastening bolts 3, and the upper, lower, left, and right sides of the lower end cover 2 are respectively provided with An inwardly recessed fastening bolt groove 21, the bottom of the fastening bolt groove 21 is provided with a connecting through hole 22, and a threaded hole is provided on the upper end cover 1 in cooperation with the connecting through hole 22, and the fastening bolt 3 is arranged on In the fastening bolt groove 21, the upper end cover 1 and the lower end cover 2 are fixedly connected together through the connecting through hole 22 and the threaded hole. One end of the rotating shaft 4 is fixed on the upper end cover 1, and the other end passes through the lower end. The bearing 5 provided on the cover 2 extends to the outside of the lower end cover 2. The bearing 5 is arranged in the installation groove provided in the center of the lower end cover. The two sides of the inner ring of the bearing 5 are provided with extension parts 51. The extension The part 51 and the corresponding rotating shaft 4 are provided with a through hole, and the connecting pin 6 fixedly connecting the inner ring extension part 51 of the bearing 5 and the rotating shaft 4 is inserted in the through hole, and the bearing 5 is encapsulated by the cover plate 7 fixed on the mounting groove. In the installation groove, the cover plate 7 is fixed on the inner side of the lower end cover 2 by screws 8 .

When the motor is in use, the leftward axial force generated by the rotating shaft 5 directly acts on the bearing 5, and the bearing 5 is encapsulated in the lower end cover 2 through the cover plate, so that the axial force directly acts on the lower end cover 2, reducing the The force acting on the fastening bolt 3 prevents the fastening bolt 3 from loosening.

The utility model has been described above only with the embodiments, but the utility model is not limited to the above-mentioned size and appearance examples, and should not constitute any limitation of the utility model. As long as any improvement or modification made to the utility model falls within the scope of protection claimed by the claims of the utility model.
