Cleaning Of Cylindrical Roller Bearings

wallpapers Industry 2021-01-19
The rolling element is a radial rolling bearing of cylindrical rollers. The internal structure of the cylindrical roller bearing adopts the parallel arrangement of the rollers, and the spacers or spacers are installed between the rollers, which can prevent the inclination of the rollers or the friction between the rollers, and effectively prevent the increase of the rotation torque.
The disassembly of the inner ring can be the easiest to pull out with a press. At this time, pay attention to let the inner ring bear its pulling force. Furthermore, the pull-out clamps shown are mostly used, and no matter what kind of clamps, they must be firmly clamped to the side of the inner ring. For this reason, it is necessary to consider the size of the shoulder of the shaft, or study the processing of the upper groove at the shoulder in order to use the drawing fixture.
The oil pressure method is used for the inner ring disassembly of large bearings. Oil pressure is applied through the oil hole provided in the bearing to make it easy to draw. For bearings with a large width, the hydraulic method and the drawing fixture are used together for disassembly.
Induction heating can be used to disassemble the inner ring of cylindrical roller bearings. The method of drawing after heating the part in a short time to expand the inner ring. Where a large number of these bearing inner rings need to be installed, induction heating is also used.
When disassembling the bearing for inspection, first make a record of the appearance with photography or other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.
a. The cleaning of the bearing is divided into rough washing and fine washing, and a metal mesh rack can be placed on the bottom of the used container.
b. When rough washing, use a brush in oil to remove grease or adhesions. If you rotate the bearing in oil at this time, be careful that the rolling surface may be damaged by foreign matter.
c. When fine washing, slowly rotate the bearing in oil, and must be carried out carefully.
Commonly used cleaning agents are neutral non-water-containing diesel or kerosene, and sometimes warm lye etc. are used as needed. No matter which cleaning agent is used, it must be filtered frequently to keep it clean.
After cleaning, immediately apply anti-rust oil or anti-rust grease on the bearing.
