Description

Technical Field

[0001] The utility model relates to the field of nylon washers, and particularly to a micro motor with a graphite nylon washer. Background Art

[0002] When the motor runs, due to the interaction between the rotor and the stator, vibrations and noises will be generated. Therefore, a washer is provided at the connection between the motor shaft and the motor housing. The washer has soft elasticity, which can relieve the impact force during operation, reduce vibrations and noises. Secondly, the circular washer has a sealing performance, and can prevent dust and moisture from entering the motor interior during motor operation, protecting the internal components of the motor. A load is connected to the end of the motor shaft, and sometimes the load will apply a vertical force to the motor shaft, causing the motor shaft to tilt slightly. The slightly tilted motor shaft will press against the inner wall of one side of the washer during long-term rotation, forming a notch on the inner wall of the washer, and dust and moisture can enter the motor interior through the notch, reducing the sealing effect. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a micro motor with a graphite nylon washer, which can effectively solve the problems mentioned in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] Furthermore, both the graphite nylon washer body and the heat insulation pad are installed at the middle position of the front end of the motor housing through the washer groove.

[0007] Furthermore, a first through hole is provided at the middle position of the graphite nylon washer body, the drive shaft passes through the graphite nylon washer body through the first through hole, and the drive shaft is rotatably connected to the graphite nylon washer body.

[0008] Furthermore, a second through hole is provided at the middle position of the heat insulation pad, and the second through hole on the heat insulation pad is aligned with the first through hole on the graphite nylon washer body. The drive shaft passes through the heat insulation pad through the second through hole, and the drive shaft is rotatably connected to the heat insulation pad.

[0010] Furthermore, the drive shaft is movably connected to the washer groove, the graphite nylon washer body, and the heat insulation pad.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] During use, the graphite nylon washer body is installed in the washer groove, and the drive shaft penetrates the graphite nylon washer body and the soft rubber sleeve. When the drive shaft is slightly tilted, it will be in the tooth notch on the inner side of the graphite nylon washer body. At this time, the soft rubber sleeve will be slightly deformed, causing the hard rubber ring to tilt to keep the same direction as the drive shaft, so that the hard rubber ring is connected to the drive shaft in a sealed state, playing a role of secondary sealing and improving the sealing effect.

[0017] In order to make the technical means, creative features, achieved purposes, and functions of the utility model easy to understand, the following further elaborates the utility model in conjunction with specific embodiments.

[0018] Such as Figure 1 Figure 2As shown in the figure, a micro-motor with a graphite nylon washer includes a motor housing 1. In the middle position at the front end of the motor housing 1, there is a washer groove 2. On the motor housing 1, at the middle position of the washer groove 2, there is a drive shaft 3. Inside the washer groove 2, there is a washer component 4. The washer component 4 includes a graphite nylon washer body 403 fixed in the washer groove 2. Both the graphite nylon washer body 403 and the heat insulation pad 405 are installed at the middle position of the front end of the motor housing 1 through the washer groove 2. In the middle position of the graphite nylon washer body 403, there is a first through hole 404. The drive shaft 3 passes through the graphite nylon washer body 403 through the first through hole 404, and the drive shaft 3 is rotatably connected to the graphite nylon washer body 403. In the middle position of the heat insulation pad 405, there is a second through hole 406, and the second through hole 406 on the heat insulation pad 405 is aligned with the first through hole 404 on the graphite nylon washer body 403. The drive shaft 3 passes through the heat insulation pad 405 through the second through hole 406, and the drive shaft 3 is rotatably connected to the heat insulation pad 405. The graphite nylon washer body 403 is corrosion-resistant and wear-resistant, and has good mechanical properties.

[0019] Specifically, the heat insulation pad 405 can prevent the heat generated by the motor from being transferred to the graphite nylon washer body 403, thereby preventing the graphite nylon washer body 403 from deforming due to heat. Through the washer groove 2, the graphite nylon washer body 403 can be installed on the motor housing 1. The graphite nylon washer body 403 installed on the motor housing 1 can play a role in shock absorption and sealing.

[0020] As Figure 1 Figure 3 As shown in the figure, the heat insulation pad 405 is compounded at the bottom of the graphite nylon washer body 403. In the middle position of the graphite nylon washer body 403, there is a soft rubber sleeve 402. At the end of the soft rubber sleeve 402, there is a hard rubber ring 401 fixedly installed, and the hard rubber ring 401 is movably sleeved on the drive shaft 3. One end of the soft rubber sleeve 402 is fixed at the first through hole 404 in the middle position of the graphite nylon washer body 403, and the other end of the soft rubber sleeve 402 is fixed on the hard rubber ring 401. After the drive shaft 3 passes through the graphite nylon washer body 403, it passes through the soft rubber sleeve 402. The drive shaft 3 is movably connected to the washer groove 2, the graphite nylon washer body 403, and the heat insulation pad 405.

[0021] Specifically, when the drive shaft 3 is stressed and tilted, it will exert a hard pressure on the inner side of the graphite nylon washer body 403, thereby forming a notch in the graphite nylon washer body 403, causing the sealing of the graphite nylon washer body 403 to fail. After the sealing of the graphite nylon washer body 403 fails, the tilted drive shaft 3 will slightly deform the soft rubber sleeve 402, and then tilt the hard rubber ring 401 to keep it in the same direction as the drive shaft 3. Although the drive shaft 3 will also exert pressure on the hard rubber ring 401, the slight deformation of the soft rubber sleeve 402 absorbs the pressure, so that the hard rubber ring 401 is connected to the drive shaft 3 in a sealed state, playing a role of secondary sealing and improving the sealing effect.

[0022] It should be noted that the present utility model is a micro motor with a graphite nylon washer. In actual use, first, the graphite nylon washer body 403 is installed in the washer groove 2. After the graphite nylon washer body 403 is installed in the washer groove 2, the drive shaft 3 will penetrate through the soft rubber sleeve 402 and the hard rubber ring 401, thereby connecting the soft rubber sleeve 402 and the hard rubber ring 401 to the drive shaft 3. Under normal circumstances, the graphite nylon washer body 403 can play a role in shock absorption and sealing. When the drive shaft 3 is oppressed by load, it will tilt slightly. When the drive shaft 3 tilts slightly, the soft rubber sleeve 402 will deform slightly, so that the hard rubber ring 401 tilts to keep it in the same direction as the drive shaft 3, and the hard rubber ring 401 is connected to the drive shaft 3 in a sealed state, playing a role of secondary sealing to prevent dust and moisture from entering the interior of the motor housing 1.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
