Concrete mixer reducer bearing obstruction

For every detail of the concrete mixer reducer it has its own, the bearing is an important part of the reducer, generally the concrete mixer truck reducer has two kinds of roller bearings and ball bearings, both of which are more convenient for maintenance, can Low lubrication costs, but that is the cost of high competition, mostly used in medium-sized motors. In accordance with our repair history for many years of reducer, this day to tell you about the concrete mixer reducer bearing obstacles, I hope to help everyone better Know the mixer car reducer:

1, the concrete mixer bearing installation should not be.

To assemble a brilliant rotating bearing, it should only be subjected to radial forces. If the outer ring is mounted, the plane will be at an angle. This angle will cause the bearing clearance to be too large and may be too small. The production of active missiles is not maneuvering, so the bearing has a fever. So To properly install the concrete mixer bearing.

2, too much grease added to the concrete mixer truck

Too much bearing grease will cause a fever between the moving parts of the bearing and the grease, and the bearings are prone to wear out.

3, the concrete mixer bearing metal appearance off

The rollers, balls, inner rings and ball brackets are heavily worn. The appearance of the metal falls off and affects the bearing's moving bullets and makes a sound. This sound is the sound of a metal collision and brings about the loss of the bearing.

4, bearing clearance problem of concrete mixer

Mixer reducer axial traction, probably the axial clearance between the bearing cover and the bearing housing is too small. Large and medium reducer generally reclaim ball bearings at the non-axial end, the shaft end retracts the roller bearings. In this way, when the rotor is heated to expand, it can freely extend. Both ends of the small motor are recycled ball bearings, the bearing cover and the bearing cover should have a proper clearance. If there is no gap, the front or rear bearing cover can be a little away, may be in the bearing Between the cover and the end cover, add a thin paper gasket.

5, the concrete mixer end cap is not closed

The end cap of the mixer decelerator is not well, the internal equipment parts are not tight, so that the ball rotates out of orbit and has a fever, leading to bearing damage, affecting the normal operation of the reducer.
