Gear processingWhen manufacturing gears, manufacturers should consider how to choose annealing and normalizing processes according to the type of gear steel, gear processing manufacturer's technology and performance.So how to choose annealing and normalizing?

Usually we choose according to the carbon content of gear steel.For gear steels with a carbon content of less than 0.25%, gear manufacturers use normalizing treatment to increase strength without other heat treatment; carburized steel eliminates forging defects through normalizing, improves chip processing performance, and prepares for carburizing and quenching treatment; When the carbon content is less than 0.20%, the gear manufacturer should use high temperature normalizing; for large gear processing castings, annealing is generally used to eliminate casting stress;

Functions and types of gear manufacturers:

The transmission device of the gear manufacturer is an important part of the mechanical equipment, and the gear manufacturer has the functions of transmitting power, shifting and reversing.

Types of gear manufacturers: According to the mutual position of the gear drive shafts, it can be divided into three types:-parallel shaft transmission, intersecting shaft transmission and cross shaft transmission.

Gears driven by parallel shafts include spur gears, helical gears and herringbone gears.

Gear manufacturers use gear steels with a carbon content of 0.25%-0.50%, which are generally normalized.Among them, steel with a carbon content of 0.25%-0.35% has better cutting hardness after normalizing; although high-carbon gear steels have higher hardness after normalizing than high-quality steels, they are still positive due to high production efficiency and low cost. fire.For gear steel with a carbon content of 0.50%-0.75%, a complete annealing process is generally used.Due to the high carbon content, the hardness after normalizing is not conducive to chip processing, and the hardness after annealing is suitable for cutting.In addition, for gear steels that require quenching and tempering, annealing is generally used to reduce the hardness, then cutting, and then quenching and tempering.
