Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and particularly relates to a plane bearing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. There are many types of bearings, and plane bearings are one of them.

[0003] Plane bearings are a special type of bearings, mainly composed of a plane retainer assembly with needle rollers or cylindrical rollers or steel balls and a plane washer. The vibration-damping top rubber installed on the plane bearing mainly plays the role of buffering and shock absorption and improving driving smoothness. At present, there is no positioning structure between the plane bearing and the vibration-damping top rubber, so the bearing cover and the top rubber slip when assembled, and it is not easy to fix the assembly direction of the bearing, which eventually leads to bearing damage. Summary of the invention

[0004] The purpose of the utility model is to address the above-mentioned problems existing in the prior art and to provide a plane bearing with a positioning structure that can prevent the bearing from slipping when rotating and can fix the assembly direction of the bearing to prevent damage to the bearing due to installation in the wrong direction.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a plane bearing, including a bearing seat, the top of the bearing seat is fixedly connected with a bearing cover plate, the right side of the top of the bearing cover plate is fixedly connected with a positioning pin, the inner cavity of the bearing cover plate is penetrated by a top rubber lower cover, the top of the top rubber lower cover is fixedly connected with a top rubber upper cover, a vibration-damping top rubber is fixedly connected between the top rubber upper cover and the top rubber lower cover, and positioning holes are opened on the right sides of the tops of the top rubber upper cover and the top rubber lower cover.

[0006] The plane bearing is mainly provided with a top rubber lower cover, a bearing cover plate, a vibration-damping top rubber, a top rubber upper cover, locating pins and locating holes on the bearing upper cover. The top rubber lower cover, the bearing cover plate, the vibration-damping top rubber, the top rubber upper cover, the locating pins and the locating holes can prevent the bearing from slipping during rotation, fix the assembly direction of the bearing, and prevent the bearing from being damaged due to the wrong installation direction.

[0007] In the above-mentioned plane bearing, the inner cavities of the bearing seat and the bearing cover plate are both equipped with bearing balls, and the top of the positioning pin extends to the inner cavity of the positioning hole. In practical applications, the number of the positioning pins and the positioning holes are both three, and they are arranged in an equilateral triangle.

[0008] In the above-mentioned plane bearing, the top rubber lower cover and the top rubber upper cover are threadedly connected with mounting bolts, and the number of the mounting bolts is three. In practical applications, by providing the mounting bolts, the top rubber lower cover and the top rubber upper cover can be conveniently fixedly connected.

[0009] In the above-mentioned plane bearing, the top rubber cover includes a cover body, the outer surface of the cover body is coated with a corrosion-resistant coating, and the outer surface of the corrosion-resistant coating is coated with a wear-resistant coating. In practical applications, the corrosion-resistant coating and the wear-resistant coating are both coated on the outer surface of the cover body, the corrosion-resistant coating is used as a primer, and the wear-resistant coating is coated on the outer surface of the corrosion-resistant coating.

[0010] In the above-mentioned plane bearing, the corrosion-resistant coating is formed by coating with chlorinated rubber coating, and the wear-resistant coating is formed by coating with polyurethane elastomer coating.

[0011] In the above-mentioned plane bearing, a mounting groove is provided at the bottom of the bearing seat surface, and a metal reinforcing ring is fixedly sleeved in the inner cavity of the mounting groove.

[0012] Compared with the prior art, the advantages of this plane bearing are: it has a positioning structure during operation, which can prevent the bearing from slipping when rotating, and can also fix the assembly direction of the bearing to prevent damage to the bearing due to installation in the wrong direction.
