[0001] The utility model relates to the technical field of stator pressing rings, in particular to a motor stator pressing ring. Background Art

[0002] The stator clamp is a metal ring with an inner diameter equal to the outer diameter of the stator core and an outer diameter equal to the outer diameter of the stator winding. The stator clamp is used to hold the stator core and stator winding in place, ensuring proper operation of the motor.

[0003] The stator pressure ring is a component that fixes the elements at both ends of the motor. During the long-term use of the motor, the existing stator pressure ring is made of metal aluminum and is light and thin. Although it can achieve the effect of covering the motor components, its light and thin nature will cause the stator pressure ring structure to loosen when the motor continues to operate, thereby reducing the safety of the original fixing elements and causing them to fall off during continuous operation of the motor, resulting in a decrease in the overall operating efficiency of the motor and increasing the safety risks of motor operation.

[0004] Therefore, we designed a motor stator pressure ring. Utility Model Content

[0005] The utility model aims to provide a motor stator pressure ring in order to solve the problem of easy loosening in the prior art.

A plurality of second connection angles are provided under the first disk body for improving the fixing effect. A plurality of contact blocks are provided at the bottom of the second disk body for reducing sliding, and the contact blocks can improve the stability of the second disk body's coverage of the motor components.

[0009] Preferably, the third disc is fixedly connected to the second disc by welding, and the third disc is provided with rounded corners.

[0010] Preferably, the first disc body is provided with a plurality of first connection angles for connecting to the second disc body, and two ends of the first connection angles are fixedly connected to the first disc body and the second disc body by welding.

[0012] Preferably, the second connection corners are arranged in a ring shape on the second disk body, and the side walls of the second connection corners are fixedly connected to the second disk body through connecting blocks.

[0013] Preferably, the bottom of the second disk body is provided with a plurality of adapting grooves, and the adapting grooves are arranged in a ring shape. The contact block is trapezoidal and fixedly connected to the adapting grooves by welding. The plurality of adapting grooves are connected by a connecting groove.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model provides a pad and a third disk, so that when the first disk and the second disk cover the motor components, the overall coverage range can be effectively improved, and the protection effect of the motor components can be further enhanced. At the same time, compared with the existing technology, it can avoid the falling phenomenon caused by the long-term operation of the motor, thereby improving the operating efficiency of the motor and reducing safety hazards during operation.

[0025] A plurality of second connection angles 9 for improving the fixing effect are provided under the first disk body 1. The second connection angles 9 are mainly used to support the first disk body 1 and ensure that the first disk body 1 maintains a horizontal effect. A pad 7 for connecting the motor is provided in the second disk body 2.

The adaptation grooves 11 are arranged in a ring. There are a total of ten adaptation grooves 11. The number can determine the stability of the contact process between the second disk body 2 and the motor components. The contact block 12 is trapezoidal, which can effectively disperse the vibration and thus form a force offsetting effect. It is fixedly connected to the adaptation groove 11 by welding. Welding is an existing commonly used connection technology, which can effectively improve the connection strength and service life of the two. At the same time, it is easy to maintain. Multiple adaptation grooves 11 are connected by connecting grooves 13. The connecting grooves 13 are auxiliary connecting grooves used to improve the air circulation in the adaptation grooves 11.
