Custom Worm Gears
Worm Gears are right angle drives providing large velocity 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 reduction could be accomplished in much less space than many other types of gearing. Worm and worm gears are powered by non-intersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a sizable extent on the helix angle of the worm. Multiple thread worms and gears with higher helix position prove 25% to 50% better than one thread worms. The mesh or engagement of worms with worm gears creates a sliding action causing considerable friction and higher lack of efficiency beyond other types of gearing. The utilization of hardened and ground worm swith bronze worm gears raises efficiency.
LUBRICATION can be an essential factor to improve performance 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 increases. Proper lubrication enhances performance by reducing friction and heat.
RATIOS of worm equipment sets are determined by dividing the custom worm gear number of teeth in the apparatus by the amount of threads. Thus single threads yield higher ratios than multiple threads. All 
Ever-power. worm gear models are available with either left or right hands threads. Ever-Power. worm equipment sets can be found with Solitary, Double, Triple and Qua-druple Threads.
SAFETY PROVISION: Worm gearing should not be used as 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 after that use of an individual thread worm with a low helix angle immediately locks the worm gear get against backward rotation.
