Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically a self-locking high-efficiency locking nut for motor bearings. Background Technology

[0002] Motor bearings, also known as electric motor bearings or motor bearings, are a special type of bearing used in electric motors. The bearing used in an electric motor is a part that supports the shaft. It can guide the rotation of the shaft and also bear the load of rotating parts on the shaft.

[0003] To improve the installation stability of motor bearings, self-locking nuts with anti-slip rings on the inner ring are commonly used for fixing. However, the anti-slip rings on traditional self-locking nuts are mostly directly fixed to the inner ring of the nut. When the self-locking nut is removed, the anti-slip ring on the inner ring wears down, which reduces the locking force and affects the reliability of the self-locking nut. Furthermore, since the anti-slip ring is fixed to the inner ring of the nut, it is difficult to replace. To address these issues, we have made technological innovations based on existing self-locking high-efficiency locking nuts for motor bearings. Utility Model Content

[0004] The purpose of this invention is to provide a self-locking, high-efficiency locking nut for motor bearings, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-locking high-efficiency locking nut for motor bearings, comprising:

[0006] The nut has a first anti-slip ring and a second anti-slip ring respectively placed on its upper and lower sides. A first pressure ring and a second pressure ring are respectively placed on the opposite sides of the first and second anti-slip rings. A connecting tube and a connecting post are evenly arranged on the opposite sides of the first and second pressure rings. A first through hole is evenly opened through the top of the first anti-slip ring and the nut. The connecting tube is inserted into the first through hole. A second through hole is evenly opened through the bottom of the second anti-slip ring. The connecting post passes through the second through hole and is inserted into the connecting tube. A fixing component is placed on the outside of the connecting tube and the connecting post.

[0007] Preferably, the fixing component includes a cross bolt, the outer side of the bolt head of which is evenly provided with two sets of positioning holes, a magnetic block is embedded in the positioning hole, a round-headed pin is inserted into the positioning hole, and a spring is provided on the outer side of the round-headed pin.

[0008] Preferably, the rounded part of the rounded pin is inserted into the positioning hole and is magnetically attracted to the magnetic block.

[0009] Preferably, the outer side wall of the nut is provided with countersunk holes, which are connected to the first through hole on the outer side of the nut, and the inner side wall of the countersunk holes is provided with two sets of mounting holes.

[0010] Preferably, the outer side of the connecting pipe has a through-hole, the outer side of the connecting post has a threaded hole, and the countersunk hole is connected to the through-hole and the threaded hole.

[0011] Preferably, the cross bolt is disposed in the countersunk hole, the bolt portion of the cross bolt passes through the insertion hole and is screwed into the threaded hole, the spring is fixedly disposed in the mounting hole, and the round-headed pin is slidably disposed in the mounting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention improves the friction between the nut and the bolt fixing the motor bearing by using a first anti-slip ring and a second anti-slip ring in combination, thereby achieving a friction self-locking effect. When the first and second anti-slip rings fail due to wear, they can be easily removed and replaced by unscrewing the cross bolt. This allows the entire self-locking nut to be reused, thus reducing unnecessary waste.

[0014] When the first and second anti-slip rings are fixed to the outside of the nut using a cross bolt, the round-headed pin is driven by the spring to insert into the positioning hole on the outside of the cross bolt and is attracted by the magnet. This fixes the cross bolt in the countersunk hole of the nut, thereby improving the overall stability of the self-locking nut and ensuring its reliability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 A self-locking high-efficiency locking nut for motor bearings includes a nut 1. A first anti-slip ring 13 and a second anti-slip ring 14 are respectively installed on the upper and lower sides of the nut 1. A first pressure ring 11 and a second pressure ring 12 are respectively installed on the opposite sides of the first anti-slip ring 13 and the second anti-slip ring 14. A connecting pipe 16 and a connecting post 17 are evenly fixed on the opposite sides of the first pressure ring 11 and the second pressure ring 12. A first through hole is evenly provided through the top of the first anti-slip ring 13 and the nut 1, and the connecting pipe 16 is inserted into the first through hole. A second through hole is evenly provided through the bottom of the second anti-slip ring 14. The connecting post 17 passes through the second through hole and is inserted into the connecting tube 16. The first anti-slip ring 13 and the second anti-slip ring 14 are placed on the upper and lower sides of the nut 1, respectively. Then, the first pressure ring 11 is placed on the top of the first anti-slip ring 13, and the connecting tube 16 passes through the first through hole of the first anti-slip ring 13 and is inserted into the first through hole of the nut 1. Then, the second pressure ring 12 is placed at the bottom of the second anti-slip ring 14, and the connecting post 17 passes through the second through hole of the second anti-slip ring 14 and is inserted into the connecting tube 16. Fixing components are placed on the outside of the connecting tube 16 and the connecting post 17.

[0022] The fixing assembly includes a cross bolt 15. Two sets of positioning holes are evenly spaced on the outer side of the bolt head of the cross bolt 15. A magnet 22 is embedded in each positioning hole. A round-headed pin 21 is inserted into each positioning hole. A spring 2 is fixedly mounted on the outer side of the round-headed pin 21. The round head of the pin 21 is inserted into the positioning hole and magnetically attracted to the magnet 22. A countersunk hole is evenly spaced on the outer wall of the nut 1, and the countersunk hole communicates with the first through hole on the outer side of the nut 1. Two sets of mounting holes are evenly spaced on the inner wall of the countersunk hole. An insertion hole is through the outer side of the connecting pipe 16. A threaded hole is through the outer side of the connecting post 17. The countersunk hole communicates with the insertion hole and the threaded hole. The cross bolt 15 is mounted in the countersunk hole. The bolt of the cross bolt 15... Partially, the through-hole and threaded hole are screwed together. The cross bolt 15 passes through the countersunk hole of the nut 1 and the insertion hole of the connecting tube 16 and the threaded hole of the connecting post 17, thereby fixing the connecting tube 16 and the connecting post 17 in the first through hole of the nut 1. Then, the first anti-slip ring 13 and the second anti-slip ring 14 are pressed on the upper and lower sides of the nut 1 by the first pressure ring 11 and the second pressure ring 12 respectively. When the cross bolt 15 is tightened, its outer positioning hole is aligned with the round head pin 21. The round head pin 21 is driven by the spring 2 to be inserted into the positioning hole and magnetically attracted by the magnet 22, thereby locking the cross bolt 15 in the countersunk hole. The spring 2 is fixedly set in the mounting hole, and the round head pin 21 is slidably set in the mounting hole.

[0023] Working principle: Place the first anti-slip ring 13 and the second anti-slip ring 14 on the upper and lower sides of the nut 1, respectively. Then, place the first pressure ring 11 on top of the first anti-slip ring 13, and insert the connecting tube 16 through the first through hole of the first anti-slip ring 13 into the first through hole of the nut 1. Then, place the second pressure ring 12 on the bottom of the second anti-slip ring 14, and insert the connecting post 17 through the second through hole of the second anti-slip ring 14 into the connecting tube 16. Screw the cross bolt 15 through the countersunk hole of the nut 1 and the insertion hole of the connecting tube 16 into the threaded hole of the connecting post 17, thereby fixing the connecting tube 16 and the connecting post 17 in the first through hole of the nut 1. Then, the first pressure ring 11 and the second pressure ring 12 press the first anti-slip ring 13 and the second anti-slip ring 14 on the upper and lower sides of the nut 1, respectively. When the cross bolt 15 is tightened, its outer positioning hole is aligned with the round head pin 21, and the round head pin 21 is driven by the spring 2. Inserted into the positioning hole and attracted by the magnet 22, the cross bolt 15 is locked in the countersunk hole. After the nut 1 is screwed into the bolt fixing the motor bearing, the inner walls of the first anti-slip ring 13 and the second anti-slip ring 14 will fit tightly against the outer wall of the bolt. The cooperation of the first anti-slip ring 13 and the second anti-slip ring 14 can increase the friction between the nut 1 and the bolt fixing the motor bearing, thereby achieving a friction self-locking effect. When the first anti-slip ring 13 and the second anti-slip ring 14 fail due to wear, the cross bolt 15 can be unscrewed to remove the first pressure ring 11 and the second pressure ring 12. Then the first anti-slip ring 13 and the second anti-slip ring 14 can be easily removed and replaced. In this way, the entire self-locking nut body can be recycled, thereby reducing unnecessary waste. It should be noted that the above-mentioned nut body refers to the nut 1, the first pressure ring 11, the second pressure ring 12, the connecting tube 16, the connecting post 17 and the fixing component.
