Custom Worm Gears
Worm Gears are best angle custom worm gear drives providing large acceleration ratios on comparatively brief center distances from 1/4” to 11”. When properly installed and lubricated they function as quietist and smoothest working type of gearing. Due to the high ratios feasible with worm gearing, optimum speed reduction can be accomplished in much less space than many other types of gearing. Worm and worm gears operate 
on nonintersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a big level on the helix angle of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% better than solitary thread worms. The mesh or engagement of worms with worm gears generates a sliding action causing considerable friction and better loss of efficiency beyond other types of gearing. The usage of hardened and floor worm swith bronze worm gears raises efficiency.
LUBRICATION is an essential factor to boost efficiency in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The amount of power transmitted at a given temperature increases as the effectiveness of the gearing increases. Proper lubrication enhances performance by reducing friction and warmth.
RATIOS of worm equipment sets are dependant on dividing the number of teeth in the gear by the amount of threads. Thus one threads yield higher ratios than multiple threads. All Ever-power. worm gear sets can be found with either left or right hands threads. Ever-Power. worm gear sets can be found with Solitary, Double, Triple and Qua-druple Threads.
Basic safety PROVISION: Worm gearing should not be used while a locking mechanism to carry heavy weights where reversing actions could cause harm or damage. In applications where potential damage is nonexistent and self-locking is preferred against backward rotation then use of an individual thread worm with a low helix angle automatically locks the worm equipment get against backward rotation.
