Influence of furnace charging mode on gear deformation

During gear heat treatment, carburizing and quenching, a reasonable furnace charging method shall be adopted according to the specific conditions such as the shape and requirements of parts, so as to ensure uniform gear heating, quenching and carburizing atmosphere, so as to reduce deformation and ensure quality. Generally, there...

Study on deformation of truck cylindrical gear

1. Effect of pre heat treatment on cylindrical gear deformation Before 2010, our company adopted the ordinary normalizing method for the pre heat treatment of gear blanks, and after 2010, the isothermal annealing method was adopted for automobile gear blanks ‚ The influence of two pre heat treatment methods...

Main factors affecting heat treatment gear deformation

Among the main factors affecting the gear heat treatment deformation, the only thing that can be improved by the heat treatment department is the heat treatment itself or the material. In order to improve the cold and hot processing conditions of gears, the heat treatment plant of Hangzhou gear...

Gear corrugation, arris and cold deformation

The corrugation, arris and cold deformation of gears are less, and the damage seems less. They show a surface state of material change and surface deformation. As shown in the figure, the surface of the gear has corrugation, which is a typical state of corrugation on the hardened off-axis...
