Jaw Crusher Transmission System Fault Solution

Jaw crusher in the process of running torque or under vibration is larger, often caused by driving system fault, common are: pulley and shaft head produce gap caused by the axis head and the wheel wear and force of eccentric shaft bearing wear, etc..

Appear afore-mentioned problems, the transmission repair method is to wheel hub bore hole, repair welding or brush plating repair after machining is given priority to, but both has certain disadvantages: repair welding of high temperature thermal stress can not completely eliminate, easy cause material damage, lead to bend or break parts and the brush plating coating thickness restrictions, easy to peel. And the above two methods are based on metal repair, can't change "hard to hard" cooperate relationship, in each of the force under the comprehensive action, still can cause wear again.

The maintenance method is not very common in western countries, contemporary Europe and the United States and other developed countries to solve above problems more choose the use of polymer composite materials to repair method, application of a country is the most mature technology; it has strong adhesion, excellent comprehensive properties such as compressive strength. Can free disassembly, free on-site repair processing. Maintenance is neither single jersey with polymer material thermal stress, the influence of repair thickness is not restricted, at the same time product of metal materials do not have rolled back, can absorb the impact of vibration equipment, avoid wear and tear, and greatly prolong the service life of the equipment without, for enterprises to save a lot of downtime, creating huge economic value.

Jaw crusher frame of severe beating the reason and solution

Found in jaw crusher work should stop beating, examined from several aspects:

1. Whether the anchor bolt looseness or breakage;
2. Whether the fly geneva wheel position wandering;
3. The host basis fixed solid, already have vibration isolation measures;

The solution is the following

1. If the anchor bolt is looseness, uses a wrench to tighten the bolt i, if the bolt fracture is broken, it needs to replace the new bolt.
2. Solving the flywheel running deviation method is, remove the fly Geneva wheel cover plate, relax fly Geneva wheel set bolt, adjust slot position of wheel set back slot wheel when tight set of bolts.
3. If jaw crusher severe shaking due to the host is not stable, should reinforce the foundation, between the machines and to add tie or rubber strips.
