All you need to know about GEAR FAILURE AND HEAT TREATMENT METHODS
Gear is a simple rotating machine element that meshes with the other gear to transmit power over a certain distance. We will see some types of gear failures and heat treatment methods that prevent the wear and tear of gear and increases the fatigue life. Types of gear failures · SCORING FAILURE: Scoring is a type of gear failure which occurs if the oil film fails due to overheating of the meshing parts and the metal to metal contact produces tearing of the parts which are in relative motion and removes the metal rapidly from the surface. The criteria for selecting the best lubricating oil include choosing appropriate viscosity grade, additives, and base oil type also it should have anti-foam properties. For determining viscosity the ANSI(American National Standards Institute) or AGMA(American Gear Manufacturers Association) standard are the most common methods employed. After selecting the viscosity grade, the basic types of lubricants such as R&O (rust
