Produce description

Large gear shafts include spur gear shafts, helical gear shafts, herringbone gear shafts, double helical gear shafts, etc., which are designed and produced according to needs.

Large gear shaft is a key mechanical transmission component, usually used to transmit large torque and rotational power. It is made of high-strength, high-wear-resistant materials, such as alloy steel, cast steel, etc., to meet the requirements of high load and high-speed operation. The design of the gear shaft takes into account factors such as dynamics, strength, wear resistance and heat treatment to ensure stable operation in various harsh environments.

The machining process of large gear shafts is relatively complex and involves multiple steps. First, the appropriate raw materials are selected and heat treated to improve their mechanical properties and wear resistance. Then, through rough turning and fine turning

Lathe processing, processing raw materials into the basic shape of the gear shaft. Next, the milling process is carried out, including steps such as milling the end face and milling the keyway. Heat treatment is also an essential link. Through quenching

Fire, tempering and other treatments can improve the hardness and strength of the gear shaft. Finally, grinding is performed to make the surface smoothness of the gear shaft meet the design requirements.

Large gear shafts have the following advantages and characteristics:

  1. High strength and high wear resistance: Made of high-strength materials and specially treated, it can withstand the requirements of high load and high-speed operation, and has good wear resistance.
  2. High precision and stability: Through advanced processing equipment and technology, the dimensional accuracy and surface quality of the gear shaft are ensured, as well as the stability during high-speed operation.
  3. Long life and reliability: Strict quality control and heat treatment processes ensure that the gear shaft has a long service life and reliable transmission performance.
