Custom Worm Gears
Worm Gears are best angle drives providing large quickness ratios on comparatively short center distances from 1/4” to 11”. When properly mounted and lubricated they function as the quietist and smoothest working type of gearing. Because of the high ratios feasible with worm gearing, optimum speed reduction can be accomplished in less space than a great many other types of gearing. Worm and worm gears operate on non-intersecting 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 position prove 25% to 50% more efficient than one thread worms. The mesh or engagement of worms with worm gears generates a sliding custom worm gear china action causing considerable friction and greater lack of efficiency beyond other types of gearing. The use of hardened and surface worm swith bronze worm gears increases efficiency.
LUBRICATION can be an essential factor to boost efficiency in worm gearing. Worm equipment action generates considerable warmth, decreasing efficiency. The quantity of power transmitted at a given temperature increases as the performance of the gearing boosts. Proper lubrication enhances efficiency by reducing friction and high temperature.
RATIOS of worm gear sets are 
determined by 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 sets are available with either left or right hands threads. Ever-Power. worm equipment sets can be found with One, Double, Triple and Qua-druple Threads.
Protection PROVISION: Worm gearing should not be used seeing that a locking mechanism to hold heavy weights where reversing action can cause harm or damage. In applications where potential harm is nonexistent and self-locking is preferred against backward rotation then use of a single thread worm with a minimal helix angle instantly locks the worm gear travel against backward rotation.
