Bearings are widely used in shearing fork lifts. We know that the scissor lift bearings burn and wear easily. The following editors analyzed the wear condition of the scissor lift bearing, and analyzed the treatment method after wear. Everyone knows the solution, and I believe it will be helpful for everyone to use this kind of problem.

Failure analysis of burn abrasives on shear fork bearing

The operation of the scissor lift can cause the bearings to overheat and burn. The main performance is as follows: bearing temperature is too high, bearing rolling or occurrence of inside, outside baking blue phenomenon; The bearing and bearing pedestal expand and become "jammed". Too high temperature will make the bearing annealing, adhesion or even stuck. The reasons are as follows:

1. The movement between axes is too small

2. Unqualified lubricating oil (grease) or improper lubrication

3. The oil supply of the fork cutter elevator is insufficient and the oil pollution is serious

4. Incorrect internal clearance of the bearing

5. Improper design size, excessive tolerance of shape and position, resulting in deformation of inner ring and outer ring of the bearing; The non-uniform load, non-uniform load and serious dynamic friction loss of the rolling body lead to the heating of the shear fork bearing.

6. Incorrect installation process and method, resulting in deflection of bearing

Treatment of burn abrasive wear on the lift bearing of shear Fork

1. The uranium movement shall be strictly controlled when installing the shear fork lift, and the uranium movement shall not be too small. Please check carefully after running in and prevent false appearance during inspection.

Step 2 Use grease. Use and replace lubricants as needed to ensure oil quality and frequently replace contaminated and deteriorated lubricants

3. Too much or too little oil should not be added to prevent oil loss after temperature rise

4. Select internal clearance of scissor lift bearings according to the standard

5. Design the dimensions reasonably to avoid the machining dimension exceeding the tolerance; Select reasonable design bearings.
