Establish a lubrication maintenance system to maintain the reducer according to the 'five fixed' principle of lubrication work, so that every reducer has a responsible person to check regularly, and it is found that the temperature rise is obvious, exceeding 40℃ or the oil temperature exceeds 80℃.

QY series reducers include two series of hard-tooth surface reducers for cranes, QYS (three pivots) and QYD (base type). QY type hard tooth surface reducer QY type hard tooth surface reducer is developed on the basis of the QJ series of medium-hard tooth surface reducers for cranes.. Parallel Shaft Gearboxes Manufacturers 2. 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, the tooth surface is carburized and quenched, and the product has been ground.

It has three types: three-level, four-level and a combination of three and four-level. The product quality is stable and the performance is reliable. 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 in accordance with the requirements of domestic and foreign markets, including three basic types in 12 categories, respectively Yes: QJY2, QJYD2, QJYA2, QJY3, QJYD3, QJYA3, QJY23, QJYD23, QJYA23, QJY34, QJYD34, QJYA34.1.

QJY series reducers are suitable for various operating mechanisms of cranes, and are also widely used in the transmission mechanism of various mechanical equipment such as transportation, metallurgy, mining, chemical industry, light industry, etc
