You will be surprised to know that the first known wind turbines recorded in history were Vertical axis wind turbines, not the current dominant technology of horizontal axis wind turbines. This dates back to the 7th century B.C when vertical axis windmills were built on the Persian land. They were based on the aerodynamic drag…
Heat is generated during the operation of the gearbox due to friction between the solid surfaces of the moving parts. Most of the heat is generated by the friction between the gear teeth, and between the rollers and rings of the bearings. Depending on the type of the engaging gears, the input torque and speed,…
