After the slewing ring is used for a period of time, spots or discoloration will be found on the surface, which not only affects the territory and smoothness of the bearing surface, but also directly affects the use effect and service life of the bearing. So, how to improve the brightness of the slewing bearing surface? Is there any good way to solve it? Next, let’s follow the editor to understand it.
Electroplating is to deposit the required covering layer on the surface of the slewing bearing substrate through the point solution method to form a bright protective film. This method can not only improve the surface brightness of the slewing bearing, but also play a role in preventing surface rust. Electroplating can be divided into single metal electroplating, multi-layer combined electroplating, and alloy electroplating.
There are many factors that affect the quality of the coating, such as: pre-plating, the method and degree of purification of the plating solution, the rationality of the pre-plating method, the establishment of the plating solution system, the determination of the combination and the thickness, and the process parameters (PH value, temperature, current density) , Additives (brightener, leveling agent, stress reliever, wetting agent, dispersant), plating solution analysis and replenishment system, operation system, post-plating treatment (dehydrogenation, sealing), etc. Of course, this kind of electroplating layer only plays a protective role on the surface of the slewing bearing, and does not change the internal structure of the bearing. Wearing during daily use will still affect the brightness of the bearing and cause the risk of rust.
2, machine shaping
The metal surface layer is plasticized and changed by mechanical methods to improve the hardness and high-strength hardened layer, which can increase the density of strengthened dislocations on the surface of the slewing bearing, and refine the sub crystalline structure, thereby increasing its hardness and strength, and the surface is rough The degree value is reduced, so that the brightness of the bearing surface is improved from the appearance, and at the same time, the surface fatigue strength of the parts can be improved and the sensitivity of fatigue notches can be reduced.
The first two are how to improve the surface brightness of the slewing bearing before it is used, and the maintenance of the bearing surface brightness can only be done through later maintenance and cleaning during use.
3, do a good job in rust prevention
While the slewing ring is in use, it is necessary to choose a suitable solvent for cleaning, so that it will not damage the rust prevention process of the slewing ring surface, and will not cause serious corrosion. Cleaning the bearing surface can restore the brightness of the bearing surface.
(2) Lubrication work
Do a good job in the maintenance of bearings during daily use, and regularly perform lubrication and maintenance on the bearings. The editor of Longda also shared the oil lubrication methods of slewing bearings before you can learn. In daily use, in addition to lubrication, attention should be paid to keeping the bearing surface dry, which can also improve the brightness of the bearing surface.
The metal luster of the slewing bearing steel is actually very bright. The reason why we need to improve the brightness of the bearing surface is mostly caused by the corrosion and improper cleaning of the bearing during use. Rust and cleaning work are also very important to improve the surface brightness of the slewing ring. Doing the cleaning and maintenance work of the bearing during the use of the bearing can increase the brightness of the bearing. At the same time, the anti-rust treatment of the bearing surface before use can also increase the brightness of the slewing bearing surface.
