Gear mechanisms are mostly used systems in transmitted power and torque mechanisms and there must be minimum two gears in those systems. Nowadays, requirements of new products with high quality and low cost have been increased on production area. Therefore, machine elements working at high speeds have been designed and improved to achieve time saving in manufacturing sector. Gear wheels are widely used machine elements for a long year. They are used main parts to transmit torque and movement between input and output shafts in almost all machines even though they have different size, material and applications. Gear and Transmission Plant has the capability to produce internal and external spur & helical gears with DIN 6-quality class in between 0,5 and 7 modules and up to 330mm diameter, right & left toothed rack up to mm length and bevel-pinion gears up to 457mm diameter and 12,7 module.
