Worm gearboxes are the most commonly used gearboxes in industrial machines. They owe their popularity to their attractive price, availability, compact design and maintenance-free operation.
Worm gearbox is a gearbox in which two elements work together: a worm (made of hardened steel) and a helix (made of bronze alloy). Gearboxes can be mounted to devices by means of a flange, reaction arm or directly to the body. An important advantage of worm gearboxes is self-locking.
Motovario worm gearboxes are marked with symbols:
– NMRV, NMRV-P – worm gearbox with IEC flange for mounting an asynchronous motor
– NRV – worm gearbox’s reducer
The standard worm gearbox’s ratio is in the range from I=5 to I=100.
By using the HW helical step or by assembling two gearboxes we can achieve a gear ratio up to I=10,000. The efficiency of the worm gearboxes, depending on the gear ratio, ranges from 40% to 85%.
