The maintenance of the drum gear coupling should be carried out according to the following procedures:
1. Check the gear 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 corrosion, wear 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. When reinstalling the intermediate tube or other parts, it should be assembled according to the original markings and data.
4. Tighten the bolts evenly with a torque wrench.
5. If you need to remove the gear ring, you must use 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.
Pay attention to the installation of the drum gear coupling:
1. If it is replaced on the original equipment, it should generally be the same as the original direction. If it is a newly designed and manufactured equipment, then the more the internal and external tooth joint surfaces should be pressed without interference with other surrounding parts. The principle of more installation.
2. The requirement of the exchangeability of the essential parts of the drum gear coupling is worthy of our attention: the parts of each specification of the drum gear coupling can be exchanged. If one of them is damaged, it can be replaced with a single spare part. There is no need to change the whole, which saves maintenance time and is convenient for users.
3. The problem of parts exchange: because of the reasons for the cost of manufacturing, we use CNC machine tools to meet the requirements of users, but from the perspective of the development situation, the coupling should be guaranteed regardless of whether the user has requirements or not. Exchangeability of parts.
