Description

Technical Field

[0001] The utility model mainly relates to the technical field of connection structures, in particular to a long-life water pump motor bearing connection structure. Background Art

[0002] Motor bearings, also known as electric motor bearings or motor bearings, are special bearings specifically used in electric motors or motors. The bearing used in the motor is a part that supports the shaft. It can guide the rotation of the shaft and also bear the idling parts on the shaft. The concept of bearings is very broad. There are four types of bearings commonly used in motors, namely rolling bearings, sliding bearings, spherical bearings and oil-containing bearings. The most common motor bearings are rolling bearings, that is, bearings with rolling elements. Sliding bearings refer to bearings without rolling elements, that is, bearings that slide. The existing motor bearing connection structure is usually connected by a fixed connection, which is extremely inconvenient when the connection structure needs to be disassembled. For this reason, we propose a long-life water pump motor bearing connection structure. Utility Model Content

[0020] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0021] For examples, please refer to the attached Figure 1-5As shown, a long-life water pump motor bearing connection structure includes a motor body 1, a motor base 101 is fixedly installed at the bottom end of the motor body 1, a connecting mechanism 2 is provided at the output end of the motor body 1, the connecting mechanism 2 includes a motor shaft body 201 fixedly installed at the output end of the motor body 1, a bearing body 202 is sleeved on one end of the motor shaft body 201, a connecting sleeve 203 is sleeved on the end of the motor shaft body 201 away from the bearing body 202, and a card slot 204 is fixedly opened on the upper and lower sides of the connecting sleeve 203 close to one end of the motor shaft body 201.

[0022] Among them, slots 205 are fixedly opened on the upper and lower sides of one end of the motor shaft body 201 away from the bearing body 202, and a reset spring 206 is fixedly installed at the bottom end of the slot 205 and located on the motor shaft body 201, and a clamping block 207 is fixedly installed at one end of the reset spring 206 away from the motor shaft body 201. When the connecting structure needs to be installed, the motor shaft body 201 enters the connecting sleeve 203 by aligning the connecting sleeve 203 with the motor shaft body 201. The clamping block 207 shrinks and moves under the action of the reset spring 206. When it moves to the clamping slot 204, the clamping block 207 is reset under the action of the reset spring 206 and is clamped and fixed with the clamping slot 204, thereby completing the installation of the connecting structure. The operation is simple and practical, and the convenience is improved.

[0023] Among them, stabilizing blocks 102 are installed at the four corners of the bottom end of the motor base 101, and buffer springs 103 are fixedly installed inside the stabilizing blocks 102. The stabilizing blocks 102 and buffer springs 103 are used in combination to play a buffering role, thereby improving the service life of the motor.

[0024] Among them, sealing rings are provided at both the front and rear ends of the bearing body 202 to prevent water from entering the interior of the bearing body 202, thereby increasing the service life of the bearing body 202.

[0025] The connecting sleeve 203 is fixed by the clamping groove 204 and the clamping block 207 to prevent the connecting sleeve 203 from being displaced, and the operation is convenient.

[0026] A damper is provided inside the buffer spring 103 to prevent the buffer spring 103 from shaking repeatedly.

[0027] The specific operation mode of the utility model is as follows:

[0028] First, when the operator needs to install or disassemble the connecting structure, the operator aligns the connecting sleeve 203 with the motor shaft body 201, and the motor shaft body 201 enters the connecting sleeve 203. The internal clamping block 207 shrinks and moves under the action of the reset spring 206. When moving to the slot 204, the clamping block 207 is reset under the action of the reset spring 206 and is fixed to the slot 204, thereby completing the installation of the connecting structure. When disassembling, the two clamping blocks 207 are pressed to shrink under the action of the reset spring 206. At the same time, the connecting sleeve 203 is pulled to make the clamping block 207 disengage from the slot 204, and the disassembly is completed.

[0029] The above description of the utility model is exemplified in combination with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
