China company Dongtai QY Series Gearbox & Speed Reducer for Overhead Crane and Gantry Crane

Dongtai QY Series Crane Use Hardened Gear Reducer is mainly used in crane lifting, running, turning and luffing mechanisms. It can also be used for the transmission mechanism of various machineries such as metallurgical, mining, chemical, and light industry. The gearbox housing body is welded with steel plates, treated under annealing for stress removal, and processed by boring and milling center. The gear is made of high-quality low-carbon alloy steel, the tooth surface is carburized and quenched, finally tooth grinding in constant temperature workshop with 6 or 5 grade level. The product is stable and reliable.

Product Features

1. The QY series crane reducer includes QYD foot-mounted and QYS three-supporting points on basis on installation form.

2. It contains three stage and four stage transmission, four stage transmission ratios provide a prerequisite for the generalization of slow speed cranes

3. The gear has been properly modified for gear profile, and the gear shaft has been modified for helical line. The tooth load is evenly distributed, high strength, low noise and low vibration.

4. The three-supporting point reducer can be installed vertically, horizontally, or even at a certain angle, which is convenient and flexible.

5. Generally use oil immersion lubrication, natural cooling, forced lubrication with circulating oil is adopted during vertical installation or special circumstances.

Product Benefits

1. Compact structure, small volume, light weight.

2. High efficiency, low noise, small vibration.

3. To increase the transmission center distance, to reduce the gearbox height to meet the requirements of the operation mechanism.

4. Higher operation reliability and enhanced transmission power.

5. Long oil change period reduce the maintenance cost.

6. Speed Ratio range up to 400, meet the low speed working requirement.
