Description and elaboration of the classification of hard tooth surface reducer

Hard tooth surface reducer belongs to a kind of reducer and is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other industrial sectors.The main categories are concentrated in two types, namely: QJY type hard tooth surface reducer and QY type hard tooth surface reducer.

1. QJY type hard tooth surface reducer  

QJY type hard tooth surface reducer is a hard tooth surface (carburizing, quenching tooth surface) crane reducer developed by the factory according to the requirements of the domestic and foreign markets. It includes three basic types in 12 categories, namely: QJY2, QJYD2, QJYA2, QJY3, QJYD3, QJYA3, QJY23, QJYD23, QJYA23, QJY34, QJYD34, QJYA34.QJY series reducer is suitable for all operating mechanisms of cranes, and it is also widely used in the transmission mechanism of various machinery and equipment such as transportation, metallurgy, mining, chemical industry, light industry, etc.

2. QY type hard tooth surface reducer

The QY type hard tooth surface reducer is developed on the basis of the medium hard tooth surface reducer used in the QJ series crane.The QY type reducer is welded with steel plates, the box body is annealed and stress-relieved, the gears are made of high-quality low-carbon alloy steel, the tooth surface is carburized and quenched, and the grinding process is processed. The product quality is stable and the performance is reliable.The QY type series reducer includes two series of hard tooth surface reducers for cranes, QYS type (three fulcrum points) and QYD type (base type).It has three types of three-level, four-level and three-level and four-level combined types.
