There are hundreds of types of gear couplings, but there are two basic forms: 1. Combination of internal and external teeth; 2. Combination of end gears.Other forms are deformations on these two foundations.
The maintenance of gear coupling is generally carried out as follows:
1. Check the tooth surface meshing of the coupling. The contact area is not less than 50% along the tooth height and not less than 70% along the tooth width. There should be no serious pitting, abrasion and cracks on the tooth surface.
2. The full circle runout of the outer gear ring of the coupling is not more than 0.03mm, and the end circle runout is not more than 0.02mm.
3. If you need to remove the gear ring, you must use special tools, not knocking, so as not to bend or damage the shaft.When reinstalling, heat the ring gear to about 200°C before installing it on the shaft.The interference between the outer gear ring and the shaft is generally 0.01~0.03mm.
4. When reinstalling the intermediate tube or other parts, it should be assembled according to the original markings and data.
5. Tighten the bolts evenly with a torque wrench.
