Introduction to woodworking lathe gear damage

Gear in the wood lathe is the most common, this article bring is the main form of gear damage reasons of gear failure has broken teeth, wear, pitting, agglutination. Broken teeth: is in gear transmission due to various reasons, one or more broken tooth gear failure; Wear: gear transmission process, the relative sliding on the surface of the tooth will cause wear and tear; 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, form 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. Daily maintenance use lubrication can significantly delay or prevent the failure of the gear.
