1, the gear accuracy is mainly to control the gears in the operation of the transmission between the accuracy of the gear, such as: transmission stability, instantaneous speed of the volatility, if the reverse reverse operation, the tooth backlash is the standard, if the impact Load, should be slightly improved accuracy, thereby reducing the impact load to bring the damage to the gear.
2, if the above design requirements are relatively high, then the gear accuracy will set a little higher, and vice versa can be set at the end
3, however, the gear accuracy is set too high, will increase the processing costs, the need for comprehensive balance
4, you above the parameters are basically more commonly used gear, the accuracy can be set as: 7FL, or 7-6-6GM precision labeling explanation:
7FL: gear of the three tolerance group with the same level of 7, the tooth thickness on the F-class deviation, tooth thickness of the lower deviation of the L-level
7-6-6GM: gear group tolerance band with a precision of 7, the second set of gear tolerance with a precision of 6, the third set of gear tolerance with a precision of 6, the tooth thickness of the upper deviation G-level, tooth thickness of the lower deviation of M-class
5, for the accuracy of the gear is no formula, because there is no need to calculate, is to check the manual to come.
6, the accuracy level is determined by the results of comprehensive analysis of engineers, transmission requirements of precision, or high load, alternating load ... ... will be a little higher accuracy level
7, the accuracy level of 5,6,7,8,9,10 level, the higher the value of the higher accuracy.http://www.shinehe.com/
