Product introduction: China famous brand-Weigao reducer QY crane reducer is developed on the basis of QJ series crane medium hard surface reducer. The QY type reducer includes two series of hardened gear reducers for QYS type (three-point) and QYD type (base type). It has three types of three-stage, four-stage and three-four-stage combination. The QY type reducer is welded by steel plate, the box is annealed and de-stressed, the gear is made of high-quality low-carbon alloy steel, and the tooth surface is treated by carburizing and quenching. Grinding processing, product quality and reliable performance.
Small size and light weight. Compared with soft tooth surface and medium hard tooth surface reducer. The same load capacity reducer can reduce 2-4 equivalent frame numbers.
2. High efficiency, low noise and low vibration. The grinding gear has improved the accuracy grade, and the gear has been trimmed. The overall efficiency of each gear is 0.98, and the vibration and noise are significantly reduced.
3. High carrying capacity. The gears are carburized, quenched and grounded, and the load carrying capacity is greatly improved compared with the soft tooth surface and the medium hard tooth surface gear reducer of the tempering hobbing.
4. Adopt multi-level number to reduce single-stage speed ratio. The center distance can be opened to reduce the height of the reducer and meet the requirements of various cranes; the maximum nominal transmission ratio of the reducer reaches 400, which meets the requirements of slow cranes.
5. Three-point reducer can be installed vertically, horizontally or even at a certain angle, which is convenient and flexible.
6. This series of reducers have three or four combined type (ie, three-stage assembly type, four-stage transmission ratio) to provide the premise for the generalization of slow cranes.
