W Series Worm Gearboxes

W Series Worm Gearboxes

W series worm gearboxes are the most common type of worm gearboxes, in that demands for such gearboxes have been increased in today’s market where there are space constraints and a need for high power transmission. Such gearboxes are similar to NMRV worm gearboxes and are cubical in shape. The main difference is that the shell in such gearboxes is made of aluminum, which results in a better heat transfer and higher power efficiency in comparison to U series worm gearboxes.

At present, these gearboxes are produced in 7 sizes and at different ratios. They are used in different industries, including packing machinery, food, wood and paper, lifts, agricultural, mixers, and other industries.

Advantages:

• Economical;
• Low noise;
• Very high power capacity;
• Minimum space needed for installation;
• High Safety factor;
• High life span;
• Various installation modes;
• Wide output speed selection range;
• Wide output torque selection range.

Disadvantages:

• They cannot be used at 1500 rpm.
• High operating temperature (due to the gear engagement mechanism);
• Relatively low efficiency (up to 65%).
