Drum gear coupling and how to adjust it the disadvantages

Drum gear coupling in the design process of its radial standard is relatively small, so the bearing capacity is relatively large, but it is often used for low speed and heavy load working conditions of shafting transmission, high precision and dynamic balance of gear coupling can be used for high-speed transmission, such as the shafting transmission of steam turbine. Because the angular compensation of the drum type coupling is greater than that of the straight type coupling, this kind of coupling is commonly used in the country, and the straight type coupling is attributed to the selected goods, the user should try not to choose.


The main reasons for the shortcomings of the drum gear coupling are as follows:
1. Lack of oil or lack of oil for the coupling of lifting accessories. Or improper use of oil, constitute oil calcification, resulting in tooth surface can not be lubricated, or lubrication is not good, tooth surface wear is serious, this situation only needs to replace the new grease, the use of qualified grease oil, avoid oil leakage, oil quantity can be avoided.

2. The levelness and coaxial over-loss of the two shafts are too large, which is higher than the compensation planning of the coupling, so that the shaft teeth and the inner teeth are not meshed correctly, constituting some contact and resulting in additional torque. And this additional moment can be decomposed into axial forces. Acting on the inner gear ring, the force depends on the size of the fault, and is proportional to the fault, the greater the fault, the greater the force, resulting in the lifting accessories coupling inner gear ring axial displacement. If the displacement is too large will not be able to control, resulting in serious gear wear, even broken teeth, surface teeth can not mesh, until can not drive. This shortcoming is difficult to dispose, need to stop production disposal. That is, straighten the reducer, or straighten the reel.

Drum gear coupling if you choose to use in the process, it is necessary for us to find out the larger part of the offset fault, so first to measure the coupling is to which side of the offset, that is, to measure the levelness and coaxiality of the spindle and the levelness and coaxiality of the reducer spindle, from the beginning according to the quality standard leveling, can reduce the shortcomings.
