Description

Technical Field

[0001] The utility model relates to the field of stainless steel plum blossom rings, in particular to a stainless steel plum blossom ring for a micro motor. Background Art

[0002] Stainless steel plum blossom ring is a special gasket or sealing element, usually made of stainless steel material, with a plum blossom shaped structural design. Stainless steel plum blossom ring has the following advantages: the plum blossom shape design enables it to adapt to and fill irregular surfaces or gaps, achieving efficient sealing effect; stainless steel plum blossom ring has a certain elasticity and resilience, can be deformed when under pressure, and then return to its original shape after the pressure is released, ensuring long-term stable sealing; due to the use of stainless steel material, plum blossom ring can resist the erosion of many chemicals and is suitable for high temperature environment.

[0003] Stainless steel plum blossom rings are generally installed at the bearings and shaft seals in micromotors to provide sealing effects at the bearings and ensure the normal operation of the micromotors. However, in existing stainless steel plum blossom rings, the structure of the stainless steel plum blossom rings is relatively simple, and it is only a gasket structure with plum blossom holes. Although the sealing effect at the bearing is relatively high, the stainless steel plum blossom rings are generally stable after installation and are prone to loosening, which in turn affects the sealing effect. When the stainless steel plum blossom rings are loose, the sealing effect at the micromotor bearings is weakened, which affects the normal use of the micromotor. Utility Model Content

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-Figure 3 As shown, a stainless steel plum blossom ring for a micromotor comprises a micromotor housing 1, a bottom shell 2 is provided at the lower end of the micromotor housing 1, and bearings 3 are provided on the micromotor housing 1 and the bottom shell 2, a stainless steel plum blossom ring 4 is provided at the connection position between the micromotor housing 1, the bottom shell 2 and the bearing 3, the micromotor housing 1 is fixedly connected to the bottom shell 2, and a fixedly connected stator 5 is provided inside the micromotor housing 1, a rotor 6 is installed inside the micromotor housing 1, the rotor 6 is located in the stator 5, and a rotating shaft 7 is installed on the rotor 6, the lower end of the rotating shaft 7 is connected to the bearing 3 on the bottom shell 2, and the upper end of the rotating shaft 7 passes through the bearing 3 on the micromotor housing 1.

[0018] When assembling the micromotor, the stator 5 is fixedly arranged on the inner wall of the micromotor housing 1, and the two bearings 3 are respectively arranged on the micromotor housing 1 and the bottom shell 2 to ensure that the bearings 3 are fixedly installed, and then the two stainless steel plum blossom rings 4 are arranged at the positions where the two bearings 3 are installed, so that the stainless steel plum blossom rings 4 contact the bearings 3, and then one end of the rotating shaft 7 on the rotor 6 is inserted into the bearing 3 on the bottom shell 2, and the rotor 6 is inserted into the stator 5 in the micromotor housing 1, so that the other end of the rotating shaft 7 on the rotor 6 passes through the bearing 3 on the micromotor housing 1 until the bottom shell 2 contacts the micromotor housing 1, and the bottom shell 2 and the micromotor housing 1 are fixed together, thereby completing the assembly of the micromotor. During the use of the micromotor, after the power is turned on, the rotor 6 rotates in the stator 5, and the bearings 3 support the rotating shaft 7. In this process, the stainless steel plum blossom rings 4 arranged at the bearings 3 play a sealing role, thereby ensuring the normal operation of the entire micromotor.

[0019] Through the above implementation scheme, the stainless steel plum blossom ring 4 includes a plum blossom ring body 401, a plug-in ring 402 and an abutment plate 403, the plum blossom ring body 401 is fixedly connected to the plug-in ring 402, and the abutment plate 403 is arranged on the plum blossom ring body 401. The stainless steel plum blossom ring 4 also includes a clamping protrusion 404 and a special-shaped hole 405. The clamping protrusion 404 is arranged on the outer surface of the plug-in ring 402, and the clamping protrusion 404 is distributed in a ring array on the plug-in ring 402. The special-shaped hole 405 is opened on the plum blossom ring body 401, and the plum blossom ring body 401 and the plug-in ring 402 are integrally formed, and the abutment Plates 403 are distributed in a circular array on the plum blossom ring body 401. Through the setting of the stainless steel plum blossom ring 4, an abutment plate 403 is set on the plum blossom ring body 401. After the stainless steel plum blossom ring 4 is installed, the abutment plate 403 contacts the bearing 3 to ensure the sealing effect of the entire stainless steel plum blossom ring 4. The plug-in ring 402 is used to connect the support for installing the bearing 3. When used in conjunction with the clamping protrusion 404, the stability of the stainless steel plum blossom ring 4 after installation can be improved, and the loosening of the stainless steel plum blossom ring 4 can be avoided, thereby ensuring the sealing effect at the bearing 3 and further ensuring the normal use of the micromotor.

[0020] During the installation of the stainless steel plum blossom ring 4, the plug-in ring 402 in the stainless steel plum blossom ring 4 is inserted into the gap reserved between the bearing 3 and the installation position to ensure that the abutment plate 403 on the plum blossom ring body 401 contacts the bearing 3. At this time, the clamping protrusion 404 arranged on the outer surface of the plug-in ring 402 tightly contacts the side wall of the installation position. Under the action of the clamping protrusion 404, the entire stainless steel plum blossom ring 4 is firmly set, and then the rotor 6 and the rotating shaft 7 are installed and set. The rotating shaft 7 passes through the special-shaped hole 405 on the plum blossom ring body 401. After the entire micromotor is assembled, it is put into use. During use, due to the action of the abutment plate 403, the stainless steel plum blossom ring 4 has a good sealing effect on the bearing 3. At the same time, the plug-in ring 402 is stably inserted into the installation position due to the action of the clamping protrusion 404, which makes the entire stainless steel plum blossom ring 4 highly stable, thereby ensuring the sealing effect on the bearing 3 and ensuring the normal use of the micromotor.
