Company News >> Requirements and analysis of the accuracy of slewing bearing gears

 
Many users do not understand the accuracy of the slewing bearing gear. Today we will explain some specific problems of the accuracy of the slewing bearing teeth. I hope to help you!
1. The accuracy of the slewing bearing gear is mainly to control the accuracy of the transmission between the gears during operation;
2. If the user's design requirements are relatively high, the accuracy of the slewing bearing gear must be set slightly higher, and vice versa.
3. The accuracy of the slewing bearing gear is set too high, which will increase the processing cost and require a comprehensive balance;
4, the more commonly used gears, the accuracy can be set to: 7FL, or 7-6-6GM accuracy;
5, the determination of the accuracy of the slewing bearing is the result of the comprehensive analysis of the engineer, the transmission requirements are precise, or high load, alternating load, etc., the accuracy level is set a little higher;
6, the slewing bearing accuracy grades are 5, 6, 7, 8, 9, 10, the smaller the value, the higher the accuracy;
7. The slewing bearing (tooth thickness) deviation grade is also the level given by the designer in the specific working conditions. The precision transmission is higher, the general machinery is lower, the closed transmission is higher, and the open transmission is lower;
8. The slewing bearing (tooth thickness) deviation grades are C, D, E, F, G, H, J, K, L, M, N, P, R, S grades, C-level clearance is larger, S-level clearance is better small;
9. Regardless of the slewing bearing accuracy level or the deviation level, the higher the setting, the higher the processing cost. After the comprehensive analysis, an appropriate accuracy level and deviation level are given.
