Hard tooth surface reducer is a kind of reducer, which is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other industrial sectors.The main classification focuses on two types, namely: QJY type hardened gear reducer and QY type hardened gear reducer.
1. QJY type hard tooth surface reducer
QJY type hard tooth surface reducer is a hard tooth surface (carburized, quenched tooth surface) crane reducer developed by the factory according to the requirements of domestic and foreign markets, including three major categories and 12 basic types, namely: QJY2, QJYD2, QJYA2, QJY3 , QJYD3, QJYA3, QJY23, QJYD23, QJYA23, QJY34, QJYD34, QJYA34.QJY series reducers are suitable for the various operating mechanisms of cranes, and are also widely used in the transmission mechanisms of various mechanical equipment such as transportation, metallurgy, mining, chemical industry, and light industry.
2. QY type hard tooth surface reducer
QY type hard tooth surface reducer is developed on the basis of QJ series crane with medium hard tooth surface reducer.The QY reducer is welded with steel plates, the box body is annealed to relieve stress, the gear is made of high-quality low-carbon alloy steel, the tooth surface is carburized and quenched, and it is ground. The product quality is stable and the performance is reliable.QY series reducers include QYS type (three pivots) and QYD type (pedestal type) two series of hard tooth surface reducers for cranes.It has three types: three-level, four-level and three-four-level combination.
