Product Description

NMRV series worm-gear reduction gearboxs are important transmission machineries. With the features of light-weight, compactibility and flexibility, they well meet the various demands of customers. The series products are applicable for lots of industrial fields, such as cranes, textile industry, metallurgy, conveyor machines, printing and dying, foodstuff industry etc.

Main Features

A gearbox designed using a worm and worm-wheel is considerably smaller than one made from plain spur gears, and has its drive axes at 90° to each other. With a single start worm, for each 360° turn of the worm, the worm-wheel advances only one tooth of the gear wheel. Therefore, regardless of the worm’s size (sensible engineering limits notwithstanding), the gear ratio is the "size of the worm wheel – to – 1". Given a single start worm, a 20 tooth worm wheel reduces the speed by the ratio of 20:1. With spur gears, a gear of 12 teeth must match with a 240 tooth gear to achieve the same 20:1 ratio. Therefore, if the diametrical pitch (DP) of each gear is the same, then, in terms of the physical size of the 240 tooth gear to that of the 20 tooth gear, the worm arrangement is considerably smaller in volume.

Unlike with ordinary gear trains, the direction of transmission (input shaft vs output shaft) is not reversible when using large reduction ratios. This is due to the greater friction involved between the worm and worm-wheel, and is especially prevalent when a single start (one spiral) worm is used. This can be an advantage when it is desired to eliminate any possibility of the output driving the input. If a multistart worm (multiple spirals) is used then the ratio reduces accordingly and the braking effect of a worm and worm-gear may need to be discounted, as the gear may be able to drive the worm.

Worm gear configurations in which the gear cannot drive the worm are called self-locking. Whether a worm and gear is self-locking depends on the lead angle, the pressure angle, and the coefficient of friction.

Dimensions of NMRV30

Characteristics
1 A simple and compact way to achieve a high torque
2 low speed gear ratio, for example, helical gears are normally limited to gear ratios of less than 10:1 while worm-and-
gear sets vary from 10:1 to 500:1
3 Low noise, because of the composition of the worm and gear, NMRV series own a quiet and smooth meshing action
4 They are fit for various mounting positions
5 It is not possible for a worm wheel to drive a worm unless certain conditions are met
