NMRV Worm Gear Units
Design for customer demand, dedication for customer satisfaction
Structure Features
1. high qualitgy die casting aluminum alloy housing, suitable for universal mounting.
2. Heat sink design for cooling provides great surface area and higher thermal capacity than the casting iron housings
3. 571 to 150, with power scope from 60W to 15kW.
4. Larger speed ratio range .each single frame size has 12 ratios from 5: 1 to 100: 1
5. Hardened worm with fine grinding has zhe features of higher efficiency and big output torque. 6. Low noise and stably running, can adapt long term work condition in terrible environments
7. Light weight high mechanical strength. 8. Modularization combination DRV extend the ration of NMRV reducers from i=5: 1 to 5000: 1
Main Materials
1. Housing: die-cast aluminum alloy(frame size 571 to 090);
cast iron(frame size: 110 to 150);
2. Worm: 20Cr, carbonize&quencher heat treatment make the hardness of gear’s surface up to 58-62HRC, retain carburized layer’s thickness between 0.3 and 0.5mm after accurate grinding.
3. Worm wheel: wearable nickel bronze alloy.
