Bending and Fracture Reason of Eccentric Shaft of Jaw Crusher and Its Measures

author:dahua1 time:2019-06-03

Bending and fracture reason of eccentric shaft:

1. The jaw crusher tilts in the process of lifting, and thus causing the eccentric shaft bending.

2. The hardness of crushed materials is stronger than that in specification.

3. The main body of jaw crusher is in the state of overload running for a long time.

4. Unsuitable heat treatment of eccentric shaft, the concentration stress causing the shaft break.

The measures of eccentric shaft:

1. When replacing the new eccentric shaft, should correct lift the main body of jaw crusher.

2. When replacing the new eccentric shaft, should choose the proper crusher according to the compressive strength.

3. When replacing the new eccentric shaft, should set the work load.

4. When replacing the new eccentric shaft, should use the qualified heat treatment shaft.
