Gear accuracy is mainly to control the gears in the operation of the transmission of precision between gears, such as: the smoothness of the transmission, the volatility of the instantaneous speed, if there is alternating reverse operation, its tooth side gap to achieve the minimum, if there is an impact load, should slightly improve the accuracy, thus reducing the impact load brought to the gear damage.
Accuracy levels are 5, 6, 7, 8, 9, 10, the smaller the value, the higher the accuracy
(tooth thickness) deviation grade is also the designer comprehensive specific working conditions given the grade, precision transmission to a higher point, the general machinery to a little lower, closed drive to a higher point, open drive to a little lower.
(tooth thickness) deviation level has C, D, E, F, G, H, J, K, L, M, N, P, R, S class, the C-class clearance is the largest, the S-class gap is the smallest.
Whether it is the accuracy level, or the deviation level, the higher the set, the higher the processing cost, the need for comprehensive analysis after the specific given an appropriate level of accuracy and deviation level
