Description

Technical Field

[0001] The utility model relates to a motor bearing with a protection structure, in particular to a motor bearing with a protection structure applied in the field of bearing parts. Background Art

[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. In today's motor work, many power tools are used in scenes with a lot of dust and moisture. The working environment of motor bearings is relatively harsh. If they operate in this working environment for a long time, more dust and moisture will enter the bearings and deteriorate the grease, causing the bearings to get stuck and fail, resulting in failure of the entire machine.

[0003] In order to solve the problem that the working environment of motor bearings is relatively harsh and that long-term operation in this working environment will cause more dust and moisture to enter the bearings and deteriorate the grease, resulting in the bearings getting stuck and failing, the motor bearings on the market use a design with sealing rings in front and behind them, which has a certain market share.

[0004] However, there is still a risk of leakage in the gap between the sealing ring and the bearing, so it is necessary to design a motor bearing with a protective structure to solve the above problem. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that there is still a risk of leakage in the gap between the sealing ring and the bearing.

[0006] In order to solve the above problems, the utility model provides a motor bearing with a protective structure, including a bearing outer ring and a bearing body arranged in the bearing outer ring, the bearing body including two outer large rings and an inner small ring which fit each other, sealing rings are arranged at the front and rear ends of the bearing body, loading and unloading rings are installed at the front and rear ends of the bearing outer ring, the front and rear sides of the loading and unloading rings are rotatably connected with self-rotating rings, one end of the self-rotating ring close to the inner small ring is fixedly connected with a clamping inner ring, one end of the clamping inner ring close to the inner small ring is fixedly connected with a raised plug ring, and the left and right ends of the inner small ring are provided with recessed clamping rings.

[0007] In the above-mentioned motor bearing with a protective structure, this solution plays a preliminary protective role by installing the bearing body into the outer ring of the bearing, which can effectively prevent the entry of dust and the loss and volatilization of grease, thereby significantly improving the service life of the bearing body.

[0008] As a further improvement of the present application, the corresponding recessed clamping ring and the raised plug ring abut against each other.

[0009] As a further improvement of the present application, a hole is provided at the inner end of the rotating circle.

[0010] As a further improvement of the present application, a motor output shaft is connected to the hole and the inner small ring of the inner sleeve, and the motor output shaft passes through the inside and outside of the outer ring of the bearing.

[0011] As another improvement of the present application, the lower end of the outer ring of the bearing is fixedly connected to the bearing seat, and the left and right ends of the bearing seat are both threadedly connected with fixing bolts.

[0012] As another improved supplement of the present application, an oil nipple is provided at the upper end of the outer ring of the bearing, and a plug-in bolt is threadedly connected to the upper end of the oil nipple.

[0013] In summary, this solution plays a preliminary protective role by installing the bearing body into the outer ring of the bearing, which can effectively prevent the entry of dust and the loss and volatilization of grease, thereby significantly improving the service life of the bearing body, and two abutting inner rings are arranged between the bearing body and the outer ring of the bearing, and the raised plug ring and the recessed clamping ring are in a mutually engaged state, which can further separate the position between the inner small ring and the sealing ring, thereby improving the protection performance against external dust and foreign matter accidentally entering the outer ring of the bearing through the connection position between the inner small ring and the sealing ring.

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method:

[0021] Figure 1-3It is shown that it includes a bearing outer ring 1 and a bearing body 8 arranged in the bearing outer ring 1. The bearing body 8 includes two outer large rings 9 and an inner small ring 11 that fit each other. Sealing rings 10 are arranged at both the front and rear ends of the bearing body 8. Loading and unloading rings 3 are installed at both the front and rear ends of the bearing outer ring 1. The front and rear sides of the loading and unloading ring 3 are rotatably connected with rotation rings 4.

[0022] Figure 2-3 It is shown that one end of the rotating ring 4 close to the inner small ring 11 is fixedly connected with a clamping inner ring 14, and one end of the clamping inner ring 14 close to the inner small ring 11 is fixedly connected with a raised plug ring 13. Both left and right ends of the inner small ring 11 are provided with recessed clamping rings 12, and the corresponding recessed clamping rings 12 and raised plug rings 13 are abutted against each other. A hole 15 is provided at the inner end of the rotating ring 4, and a motor output shaft 16 is connected to the hole 15 and the inner small ring 11, and the motor output shaft 16 passes through the inside and outside of the bearing outer ring 1.

[0023] Figure 1-3 It is shown that the present scheme plays a preliminary protective role by installing the bearing body 8 into the bearing outer ring 1, and uses a customized bearing seat 2 for the bearing body 8, which effectively accommodates and protects the bearing body 8, and can effectively prevent the entry of dust and the loss and volatilization of grease, thereby significantly improving the service life of the bearing body 8, and two mutually abutting inner rings 14 are arranged between the bearing body 8 and the bearing outer ring 1, and the abutting inner rings 14 are blocked at the connection position between the inner small ring 11 and the sealing ring 10, which can play a role in protecting the position between the inner small ring 11 and the sealing ring 10, and the raised plug ring 13 and the recessed clamping ring 12 are in a mutually engaged state, which can further make the position between the inner small ring 11 and the sealing ring 10 a partition, thereby improving the protection performance against external dust and foreign matter accidentally entering the bearing outer ring 1 through the connection position between the inner small ring 11 and the sealing ring 10.

[0024] The second implementation method:

[0025] Figure 1 It is shown that the lower end of the bearing outer ring 1 is fixedly connected to the bearing seat 2, the left and right ends of the bearing seat 2 are threadedly connected with fixing bolts 5, the upper end of the bearing outer ring 1 is provided with an oil nozzle 6, the upper end of the oil nozzle 6 is threadedly connected with an insertion bolt 7, and the oil nozzle 6 is arranged on the bearing outer ring 1 at the same time, and the bearing body 8 can be repaired and maintained by removing the insertion bolt 7.
