Numerical control woodworking lathe gear failure cause

Numerical control woodworking lathe will work according to the gears in motion, but the problem is the gear if there is a problem, we should be how to handle? Here, just simple introduce for everybody: the main form of failure of gear agglutination, wear, broken teeth, pitting. Agglutination: when the gear at high speed, large load or under the condition of lubrication failure, direct contact with the two tooth surface formation of local high temperature contact region appear large-area adhesion phenomenon, for gluing. Wear: gear transmission process, the relative sliding on the surface of the tooth will cause wear and tear; Broken teeth: is in gear transmission due to various reasons, one or more broken tooth gear failure; Pitting: gear transmission process, the contact stress of gear contact each point on the surface of a pulsating cycle change, after a period of time, due to the contact surface of metal fatigue and the formation of a small fatigue crack, crack extension caused by metal flake, formation of pitting corrosion.
