Product introduction: China famous brand - Weigao reducer QJR-D series reducer is suitable for all running mechanisms of cranes. It is also widely used in the transmission mechanism of various mechanical equipment such as transportation, metallurgy, mining, chemical industry and light industry. The QY series 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 crane reducer is welded by steel plate, the box is annealed and destressed, the gear is made of high-quality low-carbon alloy steel, the tooth surface is treated by carburizing and quenching, and Grinding processing, product quality and reliable performance.
1. Low vibration, low noise, high energy saving and stable operation;
2. The speed reduction ratio range is wide, and the nominal speed ratio is 10-200;
3. The mechanical efficiency is high, the level is 96%, and the third level is 94%;
4. Due to the forging and quenching and tempering treatment of 42CrMo and 35CrMo, the gear shaft and gear are separately produced, so the service life is long. High carrying capacity;
1. Working environment temperature is -40-45 °C
2. Can run in both directions
3. The high speed shaft speed is not more than 1000r/min:
4. The peripheral speed of the gear is not more than 16m/s.
