Description

Technical Field

[0001] The utility model relates to the field of oil-impregnated bearings, and more specifically, to an oil-impregnated bearing with a protection structure. Background Art

[0002] An oil-impregnated bearing, that is, a porous bearing, uses metal powder as the main raw material. The oil-impregnated bearing is a sintered body made by powder metallurgy. It is inherently porous and has technical advantages such as being able to freely adjust the quantity, size, shape, and distribution of pores during the manufacturing process. The oil-impregnated bearing has the characteristics of low cost, vibration absorption, low noise, and no need to add lubricating oil during a long working time, and is particularly suitable for working environments where lubrication is difficult or oil contamination is not allowed. The porosity is an important parameter of the oil-impregnated bearing. An oil-impregnated bearing working under high speed and light load requires a large oil content and a high porosity; an oil-impregnated bearing working under low speed and large load requires high strength and a low porosity. When the oil-impregnated bearing is in a non-operating state, the pores are filled with lubricating oil. During operation, the shaft rotates and generates heat due to friction, and the bearing bush expands thermally, reducing the pores. Then, the lubricating oil overflows and enters the bearing clearance. When the shaft stops rotating, the bearing bush cools, the pores recover, and the lubricating oil is sucked back into the pores.

[0003] After the existing oil-impregnated bearing is installed, dust easily enters from both ends, which may affect its use, and a small amount of oil fluid flows out from both ends, resulting in too fast consumption of the oil fluid of the oil-impregnated bearing.

[0004] Therefore, we make improvements on this and propose an oil-impregnated bearing with a protection structure. Content of the Utility Model

[0005] The purpose of the present utility model is to address the problem that after the existing oil-impregnated bearing is installed, dust easily enters from both ends, which may affect its use, and a small amount of oil fluid flows out from both ends, resulting in too fast consumption of the oil fluid of the oil-impregnated bearing.

[0006] To achieve the above-mentioned utility model purpose, the present utility model provides the following technical solutions:

[0007] An oil-impregnated bearing with a protection structure to improve the above problems.

[0008] Specifically, this application is as follows:

[0009] It includes an oil-impregnated bearing body. Protection pads are arranged on both side walls of the oil-impregnated bearing body. A connection pad is fixedly connected to the side wall of the protection pad. A clamping pad is fixedly connected to the side wall of the connection pad. A connection groove is formed in the connection pad. A rubber plug is fixedly connected to the side wall of the protection pad. A clamping groove is formed in the side wall of the oil-impregnated bearing body. A clamping post is fixedly connected in the clamping groove. One end of the clamping post is fixedly connected with a conical rubber blocking piece

[0010] As a preferred technical solution of the present application, a tapered groove is provided on the side wall of the protective pad. The tapered groove communicates with the connecting groove. The tapered groove matches the tapered rubber flap, and the connecting groove matches the clamping post.

[0011] As a preferred technical solution of the present application, a circular groove is provided on the side wall of the oil-impregnated bearing body, and the circular groove cooperates with the rubber plug.

[0012] As a preferred technical solution of the present application, the diameter of the tapered groove is larger than the diameter of the connecting groove.

[0013] As a preferred technical solution of the present application, a wear-resistant coating is provided on the inner side wall of the protective pad.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the solution of the present application:

[0016] 1. By pressing the connecting pad and the clamping pad on the side wall of the protective pad into the clamping groove (when pressing, the clamping pad deforms and then is clamped into the clamping groove), while pressing the connecting pad, the tapered rubber flap deforms. After the tapered rubber flap penetrates through the connecting groove, it enters the tapered groove. At the same time, the clamping post is inserted into the connecting groove on the connecting pad, and then the protective pad is pressed again, so that the rubber plug on the protective pad is inserted into the circular groove on the side wall of the oil-impregnated bearing body, effectively avoiding dust from entering from both ends of the oil-impregnated bearing. Moreover, when in use, the oil is easy to flow out from both ends, and the protective pad can also reduce the too-fast loss of the oil of the oil-impregnated bearing. In addition, the protective pad is installed by a clamping method, which is convenient for replacing it, solving the problems in the prior art that dust is easy to enter from both ends, which may affect its use, and a small amount of oil flows out from both ends, resulting in too-fast use of the oil of the oil-impregnated bearing.

[0031] Example:

[0032] As Figures 1-7 shown, this embodiment proposes an oil-impregnated bearing with a protection structure, including an oil-impregnated bearing body 1. Protection pads 2 are provided on both side walls of the oil-impregnated bearing body 1. A connecting pad 3 is fixedly connected to the side wall of the protection pad 2. A clamping pad 4 is fixedly connected to the side wall of the connecting pad 3. A connecting groove 6 is formed in the connecting pad 3. A rubber plug 5 is fixedly connected to the side wall of the protection pad 2. A clamping groove 7 is formed in the side wall of the oil-impregnated bearing body 1. A clamping post 8 is fixedly connected in the clamping groove 7. One end of the clamping post 8 is fixedly connected with a conical rubber stop 9.

[0033] In order to make the installation of the protection pad 2 more firm, a conical groove 10 is formed in the side wall of the protection pad 2. The conical groove 10 communicates with the connecting groove 6. The conical groove 10 matches the conical rubber stop 9. The connecting groove 6 matches the clamping post 8. While pressing the connecting pad 3, the conical rubber stop 9 deforms. After the conical rubber stop 9 penetrates through the connecting groove 6, it enters the conical groove 10. At the same time, the clamping post 8 is inserted into the connecting groove 6 on the connecting pad 3.

[0034] In order to make the installation of the protection pad 2 more firm, a circular groove 12 is formed in the side wall of the oil-impregnated bearing body 1. The circular groove 12 cooperates with the rubber plug 5. Press the protection pad 2 to insert the rubber plug 5 on the protection pad 2 into the circular groove 12 on the side wall of the oil-impregnated bearing body 1.

[0035] The diameter of the conical groove 10 is larger than the diameter of the connecting groove 6.

[0036] In order to make the protection pad 2 more wear-resistant, a wear-resistant coating 11 is provided on the inner side wall of the protection pad 2.

[0037] The protection pad 2 and the connecting pad 3 are both made of nitrile rubber, which has the advantages of good oil resistance, high wear resistance, good heat resistance, and strong adhesion.

[0038] The clamping pad 4 is made of ordinary rubber.

[0039] In this embodiment, the model of the oil-impregnated bearing is: HX001

[0040] Specifically, when the oil-impregnated bearing with a protection structure is in use: pick up the protection pad 2, press the connecting pad 3 and the clamping pad 4 on the side wall of the protection pad 2 into the clamping groove 7 (when pressing, the clamping pad 4 deforms and is clamped into the clamping groove 7). While pressing the connecting pad 3, the conical rubber baffle 9 deforms. After the conical rubber baffle 9 penetrates through the connecting groove 6, it enters the conical groove 10. At the same time, the clamping post 8 is inserted into the connecting groove 6 on the connecting pad 3. Then press the protection pad 2 again to make the rubber plug 5 on the protection pad 2 insert into the round groove 12 on the side wall of the oil-impregnated bearing body 1, and the installation is completed. Protection pads 2 are provided at both ends of the oil-impregnated bearing of this application, which can effectively prevent dust from entering from both ends of the oil-impregnated bearing. Moreover, when in use, the oil is easy to flow out from both ends. The protection pad 2 can also reduce the excessive loss of the oil in the oil-impregnated bearing. In addition, the protection pad 2 is installed by a clamping method, which is convenient for replacing it.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present utility model is within the protection scope of the present utility model.
