Analysis of the Causes of Fast Wear and Even Broken Teeth of Impact Crusher

The Impact Crusher is a crusher that is widely used in production. Some common faults are unavoidable during their work. The size Impact Crusher gear wears quickly, and frequent breakage is a common fault. The reasons for this failure are mainly the following three aspects:

1. The normal meshing condition of the Impact Crusher gear is damaged.

The transmission principle of the Impact Crusher: the asynchronous cone drives the small Impact Crusher gear integrated with the gear shaft, the small Impact Crusher gear drives the eccentric shaft set into a large Impact Crusher gear, with taper and moving cone body The main shaft is driven by the eccentric main shaft. The axis of the main shaft is the apex of the spherical bearing, and the cone is moved around the center line of the crusher to achieve the purpose of crushing the ore.

The eccentric bushing of the Impact Crusher has a strong centrifugal effect on the eccentricity and the weight of the weight during the rotation, so that the thick side is always pressed against the frame bushing, and the thin side and the frame bushing always maintain a certain gap. Therefore, the gear of the large Impact Crusher does not rotate around its own center line during the rotation, but is half of the gap a of the frame bushing (a/2, which is a radius. It makes a circular motion around the center line of the crusher.

A pair of Impact Crusher gears are normally meshed, and it is necessary that the cones of the two gears intersect at one point. And the circle is coincident. The special operating state of the large Impact Crusher gear destroys the normal meshing relationship of the pair of Impact Crusher gears. Therefore, during the operation, a large impact load and sliding friction are generated on the tooth surface of the gear, resulting in the gear of the Impact Crusher. Impact load, wear or broken teeth are more common.

2, rigid connection drive

The transmission form of the Impact Crusher: the asynchronous motor is rigidly connected with the gear shaft through the elastic coupling. When the Impact Crusher is subjected to iron or overload operation, it is easy to cause the gear of the Impact Crusher to break.

3, frequent iron or bite by chunks

When the iron sometimes passes over the ore, the spring of the crusher plays a protective role, but when the iron is frequently or bitten by a large piece, the spring will often be ineffective, causing damage to other parts of the body, such as the size Impact Crusher gear being hit. Tooth, etc.
