Maintenance method of gear coupling

Gear coupling maintenance is generally carried out in the following ways:

1, check the coupling tooth surface meshing, the contact area along the tooth height is not less than 50%, along the tooth width is not less than 70%, the tooth surface must not have serious pitting, wear and cracks.

2. The full circular runout of the outer gear ring of the coupling is not more than 0.03mm, and the end circular runout is not more than 0.02mm.

3, back to the indirect cylinder or other parts should be assembled according to the original mark and data.

4, if you need to remove the ring, you must use special tools, do not knock, so as not to bend or damage the shaft. When back installed, the gear ring should be heated to about 200 ° C and then installed on the shaft. The interference of the outer ring and the shaft is generally 0.01~0.03mm.

5. Tighten the bolts evenly with torque wrench.
