1.QY typeHard tooth surface gear reducer 
QY type hard tooth surface gear reducer is used in QJ series cranesHard tooth surface gear reducerDeveloped on the basis of. QY series reducers include two series of hard-tooth surface reducers for cranes, QYS type (three pivots) and QYD type (base type).It has three types: three-level, four-level and a combination of three and four-level. The QY type reducer is welded by steel plate, the box body is annealed to relieve stress, the gear is made of high-quality low-carbon alloy steel, and the tooth surface is carburized and quenched, and the product is processed by grinding. The product quality is stable and the performance is reliable.
