What are the standards for gear processing that need attention?

What are the standards for gear processing that need attention? Today, Taixin precision gear factory will share with you:

1, gear processing is mainly to control the transmission accuracy between the gears in the process of operation, such as: transmission stability, instantaneous speed fluctuation, whether there is alternating reverse operation, whether the backlash is small, whether there is impact load should be slightly improved accuracy, in order to reduce the impact load caused by the damage to the gear.

2. If the above design requirements are relatively high, the gear precision must be set higher, and vice versa.

3. However, if the gear accuracy is set too high, it will increase the machining cost and overall balance.

4. The parameters above are basically common gears. The accuracy can be set to: 7FL, or 7-6-6GM.

7FL: Gear machining indicates that the accuracy of the three tolerance groups of the gear is the same 7 levels, the upper tooth thickness deviation is F level, the lower tooth thickness deviation is L level. 7-6-6GM: Gears have tolerance band accuracy of class 7. , the accuracy of the two groups of tolerance zones of the gear is level 6, the accuracy of the three groups of tolerance zones of the gear is level 6, the upper tooth thickness deviation is G, the lower tooth thickness deviation is M

5. There is no formula for calculating the gear accuracy, because it is not calculated. It is obtained from the manual.

6. The determination of precision grade is the result of comprehensive analysis by engineers. If the transmission requires high and alternating loads, the level is set higher.

7, the accuracy has 5, 6, 7, 8, 9, 10 levels. The lower the value, the higher the accuracy.

8. Deviation grade (tooth thickness) is also given by the designer according to specific working conditions. Precision transmission is higher, general machinery is lower, closed transmission is higher, open transmission is lower.

The above is the gear manufacturer for you to introduce the relevant content, I hope to help you.
