Gear Damage and its Influencing Factors
Influencing Factors – Testing Procedures – Calculation Methods – Prevention – Damage Appearance
Gearboxes are used to adjust the rotational speed and torque of drive and output devices, with gears as the central machine elements. They should perform their duties in a low-noise, low-maintenance, and most of all damage-free manner over the lifetime of the machine. Breakdowns due to damage often lead to high costs.
Employees of gearbox companies and technical departments: designers, production engineers, maintenance and repair specialists, and experts.
