Technical Field

[0001] This utility model relates to the field of motor end cover technology, and in particular to an end cover structure that improves the sealing performance of a motor. Background Technology

[0002] Motor end covers are components installed at both ends of the motor stator to fix the stator and support the rotor; they are part of the motor housing. In practical applications, motors operate in complex and diverse environments, often containing impurities such as dust, moisture, and oil. If the motor's sealing performance is poor, these impurities can easily enter the motor, leading to problems such as short circuits in the motor windings and accelerated bearing wear, thus affecting the motor's performance and lifespan. When installing the end covers onto the housing, there is a risk that the sealing rings inside the sealing grooves may fall off, affecting the motor's sealing effect. Utility Model Content

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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an end cover structure for improving the sealing performance of an electric motor, comprising: an end cover body 1, an mounting block 2 fixedly mounted on one side of the end cover body 1, a sealing groove body 201 formed on the surface of the mounting block 2, a sealing ring body 3 mounted on the inner wall of the sealing groove body 201, and a limiting bolt 4 threaded at equal intervals around the surface of the mounting block 2, the other end of the limiting bolt 4 passing through the sealing ring body 3 and threaded into the inner wall of the sealing groove body 201.

[0023] Specifically: When the device is first used, the sealing ring body 3 is installed on the inner wall of the sealing groove body 201 opened on the surface of the mounting block 2. Then, the limiting bolt 4 embedded in the thread on the surface of the mounting block 2 is rotated so that the limiting bolt 4 passes through the sealing ring body 3 and is screwed into the inner wall of the sealing groove body 201. The limiting bolt 4 is tightened so that the sealing ring body 3 is restricted after being installed on the inner wall of the sealing groove body 201. This prevents the sealing ring body 3 from falling off the inner wall of the sealing groove body 201 when the mounting block 2 is installed inside the housing. This ensures that the sealing ring does not fall off when the end cover is installed on the housing, resulting in a better sealing effect for the motor and making the device more complete.

[0024] In one embodiment, a bearing mounting seat 5 is installed on one side of the end cap body 1, and a bearing hole riveting support surface 6 is installed on the other side of the end cap body 1.

[0025] Specifically: the bearing mounting seat 5 installed on one side of the end cover body 1 is used to assemble and fix the bearing, and the bearing hole riveting support surface 6 installed on the other side of the end cover body 1 is used to position and support the bearing, so as to avoid motor noise caused by poor bearing pressing and make the device more perfect.

[0026] In one embodiment, a fixing block 7 is fixedly installed on the surface of the end cap body 1. There are two fixing blocks 7. The surface of the fixing block 7 is provided with a first mounting hole 8 and a mounting groove 9. The inner wall of the mounting groove 9 is provided with a second mounting hole 10.

[0027] Specifically: After the end cover is installed on the housing, the second mounting hole 10 opened in the inner wall of the mounting groove 9 is used to fix the end cover and the housing after assembly, so that the end cover and the housing are better fixed and installed. The first mounting hole 8 opened on the surface of the fixing block 7 is used to fix the motor and the assembly after assembly, so that the device is more complete.

[0028] In one embodiment, an exhaust hole 11 is provided on the surface of the end cap body 1, and a filter block 12 is installed on the other side of the exhaust hole 11.

[0029] Specifically: the exhaust hole 11 on the surface of the end cover body 1 is used to discharge gas when the motor is running, and the filter block 12 installed on the other side of the exhaust hole 11 blocks dust and impurities in the external environment to prevent them from entering the motor, making the device more perfect.

[0030] In one embodiment, springs 13 are installed at equal intervals around the inner wall of the sealing groove body 201, and a stabilizing plate 14 is fixedly installed at the other end of the springs 13. Circular holes 15 are opened at equal intervals around the surface of the stabilizing plate 14, and the inner wall of the stabilizing plate 14 is fitted onto the inner wall of the sealing groove body 201.

[0031] Specifically: When the sealing ring body 3 is installed on the inner wall of the sealing groove body 201, springs 13 are fixedly installed at equal intervals around the inner wall of the sealing groove body 201. A stabilizing plate 14 is fixedly installed on the other end of the springs 13. The elasticity of the springs 13 causes the stabilizing plate 14 to compress the sealing ring body 3 installed on the inner wall of the sealing groove body 201, so that the sealing ring body 3 can be stably installed on the inner wall of the sealing groove body 201. At the same time, the round hole 15 opened on the surface of the stabilizing plate 14 allows the limiting bolt 4 to pass through, so that the rubber ring in the end cap can also be stably installed inside the sealing groove without falling off, making the device more perfect.

[0032] In one embodiment, a second mounting block 16 is installed on the other side of the end cap body 1, and a sealing block 17 is fixedly installed on the surface of the second mounting block 16.

[0033] Specifically: The sealing block 17 installed on the surface of the mounting block 16 is used to extend the service life of the motor and assembly after assembly, making the device more complete.

[0034] In one embodiment, reinforcing blocks 18 are installed at equal intervals around one side of the end cap body 1. One end of the reinforcing block 18 is fixedly installed on the inner wall of the mounting block 2, and the other end of the reinforcing block 18 is fixedly installed on the surface of the bearing mounting seat 5.

[0035] Specifically, multiple reinforcing blocks 18 are installed on one side of the end cover body 1, with one end mounted on the inner wall of the mounting block 2 and the other end mounted on the surface of the bearing mounting seat 5, thereby improving the strength of the entire end cover and making the device more complete.

[0036] Working principle: When the device is first used, the sealing ring body 3 is installed on the inner wall of the sealing groove body 201 opened on the surface of the mounting block 2. Then, the limiting bolt 4 embedded in the thread on the surface of the mounting block 2 is rotated so that the limiting bolt 4 passes through the sealing ring body 3 and is screwed into the inner wall of the sealing groove body 201. The limiting bolt 4 is tightened so that the sealing ring body 3 is restricted after being installed on the inner wall of the sealing groove body 201. This prevents the sealing ring body 3 from falling off the inner wall of the sealing groove body 201 when the mounting block 2 is installed inside the housing. This ensures that the sealing ring does not fall off when the end cover is installed on the housing, resulting in a better sealing effect for the motor. The bearing mounting seat 5 installed on one side of the end cover body 1 is used to assemble and fix the bearing, and the bearing hole riveting support surface 6 installed on the other side of the end cover body 1 is used to position and support the bearing, avoiding motor noise caused by poor bearing pressing. End cover installation... After mounting on the housing, mounting holes 10 are made in the inner wall of mounting groove 9 for fixing the end cover and housing after assembly, so as to better fix the end cover and housing. Mounting holes 8 are made in the surface of fixing block 7 for fixing the motor and assembly after assembly, so as to make the device more complete. When installing the sealing ring, springs 13 are fixedly installed at equal intervals around the inner wall of sealing groove body 201. A stabilizing plate 14 is fixedly installed at the other end of spring 13. The elasticity of spring 13 causes the stabilizing plate 14 to compress the sealing ring body 3 installed on the inner wall of sealing groove body 201, so that the sealing ring body 3 can be stably installed on the inner wall of sealing groove body 201. At the same time, the round hole 15 on the surface of stabilizing plate 14 allows the limiting bolt 4 to pass through, so that the rubber ring in the end cover can be kept stably installed inside the sealing groove without falling off, so as to make the device more complete.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
