In the process of gear processing, in addition to ensuring the machining accuracy of the gear, we also need to pay attention to the problem of gear assembly. Otherwise, if we don't pay attention to gear assembly, the service life of the gear with higher accuracy will not be too long. What problems should we pay attention to in gear assembly?

1. Fit: the fit between the hole and the shaft shall meet the specified requirements. If the fixed connecting gear is not eccentric or skewed; The sliding gear shall not be engaged or stuck; The gear on the loose shaft shall not shake

2. Center distance and side clearance: ensure the accuracy of gear center distance and appropriate side clearance. If the gear backlash is too small, the transmission is not flexible, and if the backlash is too large, it is prone to impact and vibration.

3. Tooth surface contact accuracy: ensure the accuracy of tooth surface contact and the correctness of contact position. If the contact position is incorrect, the two meshing gears will have relative errors.

4. Gear positioning: ensure the accurate positioning of the gear, and the dislocation shall not be greater than the specified value.

5. Balance: the large gear with high speed shall be checked for dynamic balance after being assembled on the shaft to prevent excessive vibration.

The service life of the gear can be improved only after there is no problem with the gear processing accuracy and gear assembly accuracy. The above is an introduction to the five matters needing attention in gear assembly. Those who need gear processing are welcome to consult the HF Hefa gear manufacturer.
