Problems solved by technology

When the outer ring of the bearing is cleaned with a single-slot ultrasonic wave, the garbage is not easy to discharge, and it is easy to attach to the ring again. At the same time, the viscosity of cleaning kerosene is very high, which largely hinders the cavitation effect of the ultrasonic wave and weakens the cleaning effect of the ultrasonic wave. Not getting the cleanliness it deserves

Embodiment Construction

[0016] The technical solutions of the present invention will be described in detail below in conjunction with the examples, but the present invention is not limited to the content disclosed in the examples.

[0017] The bearing outer ring cleaning process described in the present invention includes the following steps: (1) brush cleaning uses a motor to directly drive the nylon brush to rotate and position the inner wall of the bearing outer ring and the raceway for cleaning; (2) an ultrasonic cleaning with Bearings are cleaned with an aqueous detergent as the cleaning medium, and ultrasonic waves with a frequency of 20-21kHz and a power of 1kW are used to clean the bearings cleaned by the brush; (3) The bearings cleaned by the ultrasonic wave in step (2) will Place it in the rinsing tank, and use the filtered tap water to rinse it; (4) The second ultrasonic cleaning uses the bearing water agent cleaning agent as the cleaning medium, and uses an ultrasonic wave with a frequency...

Abstract

The invention discloses a bearing outer ring washing process, which comprises the following steps of: washing by using a hairbrush so as to wash away heavy garbage such as grinding wheel dust, antirust oil dirt and the like generated in the polishing process of an outer ring; and washing tiny garbage away by using multi-slot channel type ultrasound so as to meet the requirement of high cleanliness. When observed under a microscope, a bearing washed by the washing process almost do not have the garbage with the diameter of more than 20mu m, so that the noise of the bearing is effectively reduced, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to a cleaning process for the outer ring of a bearing. Background technique [0002] At present, the cleaning of the outer ring of the domestic bearing industry generally adopts ultrasonic single-tank cleaning, and cleaning kerosene is used as the cleaning medium. When the outer ring of the bearing is cleaned with a single-slot ultrasonic wave, the garbage is not easy to discharge, and it is easy to attach to the ring again. At the same time, the viscosity of cleaning kerosene is very high, which largely hinders the cavitation effect of the ultrasonic wave and weakens the cleaning effect of the ultrasonic wave. Not as clean as it should be. For the bearings that are currently cleaned by ultrasonic single groove, under the microscope, you can clearly see the garbage with a diameter of 50 μm or even 100 μm. [0003] More than 70% of the noise and service life of miniature bearings are not up to the requirements, and more than 70% ...
