Custom Worm Gears
Worm Gears are ideal angle drives providing huge rate ratios on comparatively short center distances from 1/4” to 11”. When correctly installed and lubricated they function as the quietist and smoothest operating type of gearing. Because of the high ratios possible with worm gearing, optimum speed reduction can be accomplished in much less space than a great many other types of gearing. Worm and worm gears operate on nonintersecting shafts at 90° custom worm gear angles.
EFFICIENCY of worm gear drives depends to a large degree on the helix position of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% more efficient than single thread worms. The mesh or engagement of worms with worm gears creates a sliding action causing considerable friction and better lack of efficiency beyond other types of gearing. The usage of hardened and ground worm swith bronze worm gears boosts efficiency.
LUBRICATION can be an essential factor to improve efficiency in worm gearing. Worm equipment action generates considerable high temperature, decreasing efficiency. The quantity of power transmitted at confirmed temperature increases as the effectiveness of the gearing raises. Proper lubrication enhances efficiency by reducing friction and temperature.
RATIOS of worm gear sets are dependant on dividing the amount of teeth in the gear by the amount of threads. Thus solitary threads yield higher ratios than multiple threads. All Ever-power. worm gear pieces are available with either left or right hands threads. Ever-Power. worm gear sets are offered with One, Double, Triple and Qua-druple Threads.
Security PROVISION: Worm gearing shouldn’t be used while a locking mechanism to hold large weights where reversing actions 
can cause harm or damage. In applications where potential harm is non-existent and self-locking is preferred against backward rotation then use of an individual thread worm with a minimal helix angle automatically locks the worm equipment drive against backward rotation.
