Problems solved by technology

[0004] Traditional bearing lubricants and their lubricating elements decay with time, and the uncontrollability of the decay process can easily cause the bearing to lock up, which may lead to serious consequences. The unpredictable service life of the bearing has gradually become an engineering hidden danger
[0005] The magnetic fluid lubricant in the case of an external magnetic field can significantly reduce the friction and wear in the mechanical system, and compared with the traditional lubrication bearing, the magnetic fluid lubricated bearing has low noise and high temperature resistance, and the magnetic fluid lubricating oil film also has A certain vibration-absorbing ability can also greatly reduce friction loss and surface wear, and even eliminate wear, which is very beneficial to improving the stability and running accuracy of the bearing. However, the magnetic field in the existing magnetic fluid thrust cylindrical roller bearing is difficult. The distribution control and the magnetic fluid cannot be evenly distributed inside the rolling bearing raceway, which seriously affects the engineering application of the magnetic fluid bearing. Therefore, further improvement is needed

Abstract

The invention relates to the technical field of roller bearings, and discloses a magnetic fluid thrust cylindrical roller bearing, which comprises a shaft ring, a roller cage, a seat ring and a stationary frame from top to bottom, and the middle part of the roller cage is sequentially The rollers are arranged, and the roller cage and the rollers are arranged in the annular raceway above the seat ring, and the magnetic fluid is injected into the annular raceway of the seat ring, and the annular groove below the seat ring is provided with an annular gasket and an annular ring. Axial permanent magnet; its processing technology is also disclosed. In the present invention, the magnetic fluid is used as the thrust bearing lubricant, which can realize the bearing operation requirements of low friction, micro-vibration and high bearing capacity, and the seat ring is set as an annular raceway for the magnetic fluid and roller lubrication system, and the permanent The magnet is set at the lower part of the magnetic fluid as an external magnetic field application source, and the structure design is reasonable, which is especially suitable for precision instruments with strict operating conditions.

Description

technical field [0001] The invention relates to the technical field of roller bearings, in particular to a magnetic fluid thrust cylindrical roller bearing and its processing technology. Background technique [0002] Roller bearings are a type of rolling bearings and are one of the most widely used components in modern machinery. It relies on the rolling contact between the main elements to support the rotating parts. Roller bearings are now mostly standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy, and convenient selection. Rolling bearings are divided into ball bearings and roller bearings according to rolling elements. [0003] Roller bearings rely on the rolling contact between the main parts to support the rotating parts. Different roller bearings can withstand different radial and axial forces. When selecting roller bearings, the selection should be made according to the specific working conditions. Roller bearings ...
