What are the characteristics of material selection for WS80-23-II worm gear reducer

The WS80-23-II worm gear reducer has the following characteristics in material selection:

Worm material: Medium carbon steel or medium carbon alloy steel, such as 45 steel, 40Cr, etc., are usually selected. These materials have good comprehensive mechanical properties and can meet the requirements of worm gear after appropriate heat treatment. For example, quenching and tempering treatment can give 45 steel a certain strength and toughness, and then surface quenching can improve the hardness and wear resistance of the worm gear tooth surface, with a hardness of HRC45-55, suitable for medium speed and medium load working conditions. If it is an occasion with higher performance requirements, low-carbon alloy steel such as 20CrMnTi may be used. After carburizing and quenching treatment, the surface hardness can reach HRC58-62, and the core still maintains good toughness, which can withstand large impact loads and is suitable for high-speed and heavy-duty working conditions.

Worm gear material: Generally, cast bronze is used as the gear ring material for worm gears, commonly including cast tin bronze (such as ZCuSn10P1) or cast aluminum bronze (such as ZCuAl10Fe3). Cast tin bronze has excellent anti friction, wear resistance, and anti bonding ability, with a low coefficient of friction. It can maintain good transmission performance at high speeds and heavy loads, and is suitable for applications that require high transmission accuracy and stability. However, cast aluminum bronze has higher strength and is relatively cheaper than cast tin bronze. Although its anti friction and anti bonding properties are slightly inferior, it can still perform well under medium speed and medium load conditions.

Other component materials: The gearbox casing is usually made of gray cast iron or ductile iron. Gray cast iron has good casting performance, shock absorption performance, and cutting performance, which can meet the requirements of the box for strength and stability, while being relatively low in cost. And the mechanical properties of ductile iron are superior to gray cast iron, with higher strength and toughness. When the performance requirements for the box are high, ductile iron will be selected. In addition, bearings are generally made of bearing steel to ensure good wear resistance and rotational accuracy; Seals are often made of elastic materials such as rubber or polyurethane to prevent lubricant leakage and external dust from entering the reducer.
