Description

Technical Field

[0001] The utility model relates to the technical field of motor bearings, in particular to a motor bearing with good high temperature resistance and sealing performance. Background Art

[0002] Motor bearings, also known as electric motor bearings or motor bearings, are special bearings used in electric motors or motors. The bearings used in motors are parts that support the shaft. They can guide the rotation of the shaft and also withstand the idling parts on the shaft. Motor bearings need to withstand high temperatures and high-speed pressure, so they need to use materials that are resistant to high temperatures and have good sealing properties.

[0003] In the prior art, when motor bearings are used as motor support shafts, they are usually made of high-temperature resistant and well-sealed materials, and do not have a lubricating oil sealing structure encapsulated on both sides of the bearings, so that the motor bearings cannot achieve high-temperature resistance and good sealing.

[0004] Therefore, it is necessary to design a motor bearing with good high temperature resistance and sealing performance to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a motor bearing with good high temperature resistance and sealing performance, so as to improve the lubricating oil sealing structure of the motor bearing with double-sided bearing packaging, so that the motor bearing can achieve high temperature resistance and good sealing performance, thereby solving the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A motor bearing with good high-temperature resistance and sealing performance comprises a bearing outer ring, a bearing inner ring and a rolling element, the front and back sides of the bearing outer ring are both located at a packaging groove provided on the periphery of an axial center hole, a connecting screw hole is provided inside the packaging groove, a bearing inner ring is provided inside the bearing outer ring, a limiting groove is provided on the outer wall of the bearing inner ring and the inner wall of the bearing outer ring, a rolling element is clamped between the limiting grooves of the bearing inner ring and the bearing outer ring, a sealing convex ring is provided on the front and back sides of the bearing inner ring and located at the periphery of the axial center hole, a sealing gland is embedded and clamped on the front and back sides of the bearing outer ring and the bearing inner ring, and a connecting bolt is installed inside the outer surface of the sealing gland and embedded in the connecting screw hole.

[0008] As a preferred solution of the utility model, a plurality of connecting screw holes are distributed in a ring shape with equal intervals.

[0009] As a preferred solution of the utility model, a plurality of rolling bodies are arranged in an annular distribution.

[0010] As a preferred solution of the utility model, there are two limiting grooves in total, and the sizes of the two limiting grooves are matched and clamped on the upper and lower end surfaces of the rolling body respectively.

[0011] As a preferred solution of the utility model, a plurality of connecting through holes are arranged in an annular manner with equal intervals on the outer edge of the outer surface of the sealing gland, wherein the connecting through holes are arranged in a one-to-one correspondence with the connecting screw holes.

[0012] As a preferred solution of the utility model, a sealing groove whose size matches that of the sealing convex ring is provided on one side of the sealing gland close to the outer ring of the bearing.

[0013] As a preferred solution of the utility model, the connecting bolts are specifically cylindrical head hexagon socket screws, and a plurality of connecting bolts are arranged in a one-to-one correspondence with the connecting screw holes.

[0014] Beneficial effect: In view of the problem that the prior art cannot improve the lubricating oil sealing structure of the motor bearing with double-sided bearing packaging, resulting in the motor bearing being unable to achieve high-temperature resistant sealing and good use, in the utility model, packaging grooves with connecting screw holes are arranged on both sides of the bearing outer ring, and a sealing gland with a sealing groove is arranged in cooperation with a bearing inner ring with a sealing convex ring. The sealing groove and the sealing convex ring are pressed and clamped to each other, and the sealing gland is connected to the connecting screw hole of the bearing outer ring through a connecting bolt, so that the rolling elements between the bearing outer ring and the bearing inner ring are coated with cooling lubricating oil and can be sealed and preserved, thereby making the motor bearing achieve high-temperature resistant sealing and good use. The utility model has a simple structure and has a lubricating oil sealing structure with double-sided bearing packaging, which ensures that the motor bearing achieves high-temperature resistant sealing and good use.
