Resolving the Reasons of the Bolt Breakage of Cone Crusher

Cone crusher in the long time working, the bolt breakage may occur, so in the daily production,how to avoid cone crusher bolts?

1, the motor bracket and the contact surface of lower crusher frame are too small.
Bolts connecting the connection by friction between the contact surfaces to prevent their mutual slip ,contact surface is too small, there is relative sliding between the motor bracket and the crusher shelves, resulting in the enormous shear forces of bolt contact surface, then cause the bolt to break.
2, the motor bracket and the contact surface of crusher frame exist gap
Motor bracket and the lower frame will produce a slight and short-term gap, connecting surface will not only having a dramatic impact load, motor bracket will easy to break the bolt.
3, bolt preload does not meet the requirements.
Torsional strength bolts use a wrench to tighten the nut.If precompression is not stable, it will cause the connecting surface in uneven force, so that the bolt fractures.
From the above description, we can see, if want to ensure a stable and orderly operation of the device, not only choosing the right equipment, but also applying the right method.zrf
