high-ratio of the NMRV worm geared motor

NMRV worm geared motor and worm gears provide an effective answer for power transmission applications requiring high-ratio speed reduction in a limited space using right angle (90°), non-intersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest form of gearing.

worm gear efficiency of a worm gear drive depends on the lead angle and number of starts on the worm - and because increased efficiency is always a goal, the ratio should be kept as low as possible. To run properly, worms and worm gears used together must have the same diametral pitch and threads.

Planetary gearbox efficiency

planetary gearbox efficiency , Power losses in gear systems are associated primarily with tooth friction and lubrication churning losses.    Churning losses are relatively independent of the nature of the gears and the gear ratios - planetary gear are primarily realated to the peripheral speed of the gears passing through the fluid.  Churning losses are difficult to calculate and estimates based on experience are often used in initial gear design.   The frictional losses are related to the gear design,the reduction ratio,the pressure angle, gear size, and the coefficient of friction.
