Custom Worm Gears

Worm Gears are right angle drives providing huge acceleration ratios on comparatively short center distances from 1/4” to 11”. When properly installed and lubricated they function as the quietist and smoothest running type of gearing. Due to the high ratios feasible with worm gearing, maximum speed custom worm gear china reduction can be accomplished in less space than a great many other types of gearing. Worm and worm gears operate on nonintersecting shafts at 90° angles.

EFFICIENCY of worm equipment drives depends to a large level on the helix angle of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% better than single thread worms. The mesh or engagement of worms with worm gears generates a sliding action causing considerable friction and greater lack of efficiency beyond other styles of gearing. The utilization of hardened and floor worm swith bronze worm gears boosts efficiency.

LUBRICATION can be an essential factor to boost efficiency in worm gearing. Worm equipment action generates considerable high temperature, decreasing efficiency. The amount of power transmitted at a given temperature boosts as the efficiency of the gearing raises. Proper lubrication enhances effectiveness by reducing friction and heat.

RATIOS of worm gear sets are dependant on dividing the amount of teeth in the apparatus by the amount of threads. Thus solitary threads yield higher ratios than multiple threads. All Ever-power. worm gear models can be found with either left or right hand threads. Ever-Power. worm equipment sets are offered with Single, Double, Triple and Qua-druple Threads.

Security PROVISION: Worm gearing shouldn’t be used while a locking mechanism to hold heavy weights where reversing actions can cause harm or injury. In applications where potential damage is nonexistent and self-locking is desired against backward rotation then use of a single thread worm with a minimal helix angle instantly locks the worm equipment drive against backward rotation.
