Abstract

The bachelor thesis is dealing with the design of new driving gearbox for wire rod’s rolling mill. In the beginning of the thesis is a comparison of types of transmissions used in the industry nowadays. Construction and faults of current gearbox are described in the next chapter. The values for the desing of a gearbox are determined from the torque curve. With the help of department’s programs, new gear geometry is designed and safety is verified. For newly designed gears reaction forces are calculated and new bearings are designed. Bearings are verified for static safety and their life is calculated. Required technical documentation is located in the enclosure.
