Sullair 88290003-322 Alternative Air Compressor Couplings

The reasons for the non-rotation of the air compressor coupling are mainly as follows:

First, the two shaft levelness and coaxiality error is too large, more than the coupling, can compensate the range, so that the shaft teeth and internal teeth meshing is not correct, resulting in local contact, and the emergence of additional torque.And this additional torque can be decomposed into an axial force.On the inner ring gear, the force depends on the size of the deviation and is proportional to the deviation. The greater the deviation, the greater the force, which leads to the axial displacement of the inner ring gear of the lifting fittings coupling.If the displacement is too large to control, the gear wear is serious, even broken teeth, internal and external teeth can not mesh, until the transmission can not be.

This kind of fault treatment is more difficult, need to stop processing.

That is to recalibrate, or the reducer focus on the new alignment, or the reel focus on the new alignment.First find out the offset error of the larger part, so first to measure the coupling is to the side of the offset, that is, the measurement of the spindle's levelness and coaxiality and reducer spindle's levelness and coaxiality, according to the quality standard to copy the alignment, you can eliminate the fault.

In addition, the levelness and concentricity error of the two axes are large, resulting in the strength of the coupling when it rotates.And the above lifting accessories coupling gear wear reasons are basically similar, connecting bolts in addition to the normal force, but also subject to additional bending moment, so that it is broken.That's the main reason.This reason mostly occurs in the reduction of the spindle around the level of high difference caused by.

In addition, the bolt diameter is fine, the strength is not enough or the bolt material is poor can also cause the bolt fracture phenomenon.

Second, lifting fittings coupling oil insufficient or lack of oil.

Or improper use of grease, resulting in grease calcification, resulting in tooth surface can not be lubricate, or poor lubrication tooth surface wear serious, this situation as long as the replacement of new grease, regular injection of qualified grease oil, prevent oil leakage, oil quantity is sufficient, can be avoided.
