Description and elaboration of the classification of hard tooth surface reducers

This article describes the classification of hard tooth surface reducers.Shanghai Jinchuan Reducer introduces two types of hard tooth reducer to enhance your understanding of hard tooth reducer.This paper mainly expounds two types of QJY hard tooth surface reducer and QY hard tooth surface reducer.
1. QJY hard tooth surface reducer
QJY hard tooth surface reducer is a crane reducer with hard tooth surface (carburized and quenched tooth surface), developed by the factory according to the requirements of domestic and foreign markets, of which there are 12 basic types and three categories: QJY2, QJYD2, QJYA2, QJY3, QJY3, QJYD3, QJYA3, QJY23, QJYA23, QJY34, QJYD34 and QJYA34.QJY series reducers are suitable for all operating mechanisms of cranes, and are also widely used in transmission mechanisms of various mechanical equipment, such as transportation, metallurgy, mining, chemical industry, light industry, etc.
2. QY type hard tooth surface reducer
The crane based on the QJ series medium-sized hard-toothed reducer developed the QY hard-toothed reducer.The QY reducer is welded by steel plate, the box body is annealed and stress-relaxed, the gear is made of high-quality low-carbon alloy steel, the tooth surface is carburized and quenched, and ground.The product quality is stable and the performance is reliable.The QY series reducers include Qys (three pivots) and QYD (basic type) hard tooth surface reducers for cranes.It has three levels, four levels and three or four levels.
