How to ensure the slip ring is not burnt from the process

　　 Under normal circumstances, there will be no problems with the service life of the sliding ring. Generally speaking, the life of slip rings is shortened due to improper use or failure to comply with certain rules during use.

　　 Next, we will explain in detail how to prevent the slip ring from being burned from the perspective of technology. The so-called burn damage state of imported slip ring refers to: the race wheel, rolling element and cage of the imported slip ring rapidly heat up during rotation until they are discolored, softened, welded and damaged. Regarding the relevant information on imported slip ring lubrication, the second possibility is that the preload is too large, the speed is too large, the clearance is too small, water or other foreign objects enter.

　　 If the above two situations are not so, it means that the accuracy of the shaft and the slip ring box is poor, and the shaft deflection is large. Research needs to fit, slip ring clearance and preload, and improve the sealing device, check the accuracy of the shaft and slip ring box.

A large number of tests at home and abroad have shown that the processing quality of cage, ferrule, and steel ball has different degrees of impact on the vibration of slip ring. The processing quality of steel ball has the most obvious impact on the vibration of slip ring, followed by the processing quality of the ring. The main influencing factors are the roundness, waviness, surface roughness, and surface bumps of steel balls and ferrules. Of course, if you have an expert next to you, it is best to let him operate and follow along with you! The main cause of imported slip ring burn is due to poor lubrication of imported slip ring, improper lubricant may be used, or too much lubricant , Too little is not correct. If the workpiece is bumped during the transfer process, it will be directly reflected on the surface of the raceway, which will affect the vibration of the slip ring. Therefore, the following measures must be taken: improve the accuracy of the positioning reference surface shape; seeing this, I think everyone wants to know the solution. First of all, we must study the lubricant and lubrication method, choose the correct slip ring lubricant, and its dosage, and To correct the choice of slip ring.

　　In order to improve the accuracy of the machining reference surface and reduce the error in the grinding process, the outer diameter and end surface are the positioning benchmarks in the grinding process. The error reflection of the outer diameter to the groove super-precision is indirectly transmitted through the outer diameter to the groove grinding, and the error reflection of the groove grinding to the groove super. During the processing, the transfer is smooth and there is no bumps; the shape and position error of the blank remaining amount should not be too large, especially when the remaining amount is small, the excessive error will cause the shape accuracy at the end of the final grinding and superfinishing to not improve to the final quality requirements, which is serious Affect the consistency of processing quality.

　　We recommend that customers pay attention to the installation, lubrication, clearance and other links when using imported slip rings as accurately as possible and in place. The important structural methods of turntable slip ring seat are distinguished as follows: four-point contact ball turntable slip ring seat, double row angular contact thrust ball turntable slip ring seat, interspersed turntable slip ring seat, interspersed turntable slip ring, turntable slip ring seat is commonly used for lifting Large-scale rotary installation of transportation machinery, mining machinery, construction machinery, port machinery, marine machinery and high-precision radars.
