01 09:22:29 views: 0 at the beginning of the textile machinery non-standard bearing surface strengthening method, we introduce you to a lot of bearing the use of the above knowledge, and the side of the common types of bearing, we all know where we need to pay attention to when using the bearing, a lot of friends all know that we are bearing a lot of more phyletic, also has the very big difference in the use, we are now in textile machinery non-standard bearing, for example, to introduce some bearing some knowledge, we all know that a lot of mechanical strength of bearing has a lot of requirements, bearing right now to tell you about the method of surface strengthening.
By mechanical method of plastic deformation in the metal surface, so as to form a hardening layer with high hardness and high strength, this kind of surface strengthening method called surface deformation strengthening, also known as work hardening.
Including shot peening, sandblasting, cold extrusion, rolling, cold grinding and impact and explosion shock processing, etc.
The characteristics of these methods are: strengthening layer increased dislocation density, the crystal structure refinement, so that the hardness and strength increased, the surface roughness value decreases, and can significantly increase the surface fatigue strength of parts and reduce fatigue notch sensitivity.
This process is simple, effective reinforcement method, there is no obvious boundaries between hardening layer and matrix, the coherent structure and not easy to fall off in use.
Surface strengthening heat treatment, the use of solid-state phase transformation, the surface of parts by using the method of rapid heating treatment called surface quenching heat treatment, commonly known as surface hardening.
Including flame quenching, high frequency induction heating quenching, laser heating or electron beam heating quenching, etc.
The characteristics of these methods are: local heating surface quenching, workpiece deformation is small, fast heating and surface oxidation decarbonization is very slight.
Bearing surface strengthening, there is a big help for our use of bearing, what kind of heavy machinery, especially because many friends reflect some mechanical equipment use bearing will soon wear, need to change, this requires us to specify to master the use of some bearing habit, jiaxing needle bearing manufacturer to remind everybody, in the use of bearing products, want to often to maintain, add lubricating grease, etc. , so as to prolong the service life is bearing, as well as the use of our equipment.
