Special reinforced bearing for self-lubricating high-temperature guide rail

Abstract

The invention provides a self-lubricating reinforced bearing special for a high-temperature guide rail, and relates to the technical field of automobile accessories, the self-lubricating reinforced bearing comprises a bearing outer ring and a reinforced inner ring, the reinforced inner ring is located in the bearing outer ring, a roller is arranged between the reinforced inner ring and the bearing outer ring, and a composite protector is arranged on the periphery of the roller. And the roller is positioned in the composite protector. The cylindrical surface of the outer diameter of the bearing is changed into the large-radian curved surface, so that the contact between the outer ring of the bearing and the guide rail is changed into point contact from line contact, the operation stability and impurity adhesion resistance of the bearing are improved, the guide rail bearing operates stably on a coating line, the vibration and shaking phenomena do not exist, and the bearing can work normally at high temperature; the bearing outer ring is in point contact with the guide rail, operation is stable, deformation and inclination of the guide rail rod can be adapted, bearing lubrication can resist paint mist, lubrication is good, and the phenomenon of lubrication clamping stagnation is avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a special reinforced bearing for self-lubricating high-temperature guide rails. Background technique [0002] The existing guide rail bearings of automobile painting lines must meet the following technical level requirements when they are working: 1. The guide rail rods for suspending automobiles run smoothly; 2. The guide rail bearings can work at high temperatures and can withstand high temperature environments above 300 degrees Celsius; 3 , Bearing lubrication can work normally under high-temperature paint mist, without paint mist reaction, and not affected by paint mist. [0003] The existing standard guide rail bearings cannot meet the above requirements well during use. There are phenomena such as short bearing time, rapid failure, and frequent bearing replacement. At present, the outer ring of the bearing is a cylindrical surface, which is easy to adhere to impurities o...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art by changing the cylindrical surface of the outer diameter of the bearing into a curved surface with a large radian, so that the contact between the outer ring of the bearing and the guide rail changes from a line contact to a point contact, thereby increasing the running stability of the bearing And the ability to resist the adhesion of impurities, the guide rail bearing runs smoothly on the coating line, there is no vibration and jitter phenomenon, the bearing can work normally under high temperature, the outer ring of the bearing is in contact with the guide rail, the operation is stable, and it can adapt to the deformation of the guide rail rod and Inclined, the bearing lubrication can resist paint mist, the lubrication is good, and there is no lubrication sticking phenomenon
