How to improve wear resistance in parts processing

Avoid sliding friction pairs made of the same materials

Avoid too large thickness of white alloy

Avoid increasing the requirements for the whole part in order to improve the wear resistance of the part surface
Avoid local wear of large parts and scrap the whole parts
When white alloy is used as bearing liner, attention should be paid to the selection of bearing material and the design of bearing structure
The lubricant supply is sufficient, covering the working face
The lubricating oil tank should not be too small
Do not let the filter filter out the additive in the lubricant
The size, position and shape of oil groove of sliding bearing shall be reasonable
The amount of grease added into the rolling bearing should not be too much
Add a certain amount of wear allowance to the easily worn surface of parts
Pay attention to the adjustment of worn parts
The velocity and pressure difference between different points on the same contact surface should be small
Adopt dust-proof device to prevent abrasive wear
Avoid step wear
Contact oil seal cannot be used for sliding bearing
The easily worn parts shall be protected
For easily worn parts, the structure of automatic wear compensation can be adopted
Avoid the distance between the force point and the support point
Avoid cantilever structure or reduce cantilever length
Don’t ignore the beneficial effect of working load
Avoid using friction to transfer force for parts under vibration load
Avoid the unbalanced force in the mechanism
Avoid considering only one way of force transmission
High speed computer gong processing should not ignore the influence of part deformation on stress distribution during working
Avoid large tensile stress on iron castings
Avoid bending stress on thin rod
Avoid excessive rigidity of parts under impact load
Avoid rough surface or scratch of parts under variable stress
Residual tensile stress should be avoided on the surface of parts under variable stress
The stress concentration of parts under variable load should be avoided or reduced
Avoid that the local structures that affect the strength are too close to each other
Avoid pre deformation in machining of mechanical parts, and the deformation direction is the same as that produced by working load
The diameter of pulley and drum of wire rope shall not be too small
Avoid too many times of wire rope bending, and pay special attention to avoid repeated bending during machining of mechanical parts
Allowance shall be left at the joint of wire rope and drum during lifting
The intermediate parts of CNC machining center that can not transfer force should be avoided as far as possible
Try to avoid additional force caused by misalignment of axis during installation
Minimize the force acting on the foundation.
