The description and elaboration of the classification of gear reducer with hard tooth surface

Time：2020-05-24

Hard tooth surface reducer is a kind of reducer, 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, respectively: QJY type hard tooth surface reducer and QY type hard tooth surface reducer.

QJY type hard tooth surface reducer
QJY type hard tooth surface reducer is the factory according to the requirements of the domestic and foreign market development of hard tooth surface (carburizing, quenching tooth surface) crane reducer, including three categories of 12 basic types, respectively are: QJY2, QJYD2, QJYA2, QJY3, QJYD3, QJYA3, QJY23, QJYD23, QJY34, QJYD34. QJY series reducer is suitable for crane operation mechanism, also widely used in transportation, metallurgy, mining, chemical industry, light industry and other mechanical equipment transmission mechanism.

Two, QY type hard tooth surface reducer
QY type hard tooth surface reducer is developed on the basis of QJ series of medium and hard tooth surface reducer for cranes. QY type reducer adopts steel plate welding, the box body is annealed to stress treatment, the gear is made of high quality low carbon alloy steel, the tooth surface is carburized and quenched, and the grinding process, the product quality is stable, reliable performance. QY series reducer includes QYS type (three fulcrum) and QYD type (base) two series of crane with hard tooth surface reducer. It has three types of three, four and three four combined.
