Custom Worm Gears
Worm Gears are right angle drives providing huge swiftness ratios on comparatively brief center distances from 1/4” to 11”. When correctly installed and lubricated they function as quietist and smoothest operating type of gearing. Due to the high ratios possible with worm gearing, optimum speed reduction could be accomplished in much less space than a great many other types of gearing. Worm and worm gears are powered by nonintersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a huge degree on the helix position of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% more efficient than solitary thread worms. The mesh or engagement of worms with worm gears produces a sliding action causing considerable friction and greater 
lack of efficiency beyond other styles of gearing. The usage of hardened and floor worm swith bronze worm gears increases efficiency.
LUBRICATION is an essential factor to improve effectiveness in worm gearing. Worm gear action generates considerable heat, decreasing efficiency. The amount of power transmitted at confirmed temperature boosts as the performance of the gearing increases. Proper lubrication enhances effectiveness by reducing friction and warmth.
RATIOS of worm gear sets are determined by dividing the number of teeth in the gear by the number of threads. Thus one threads yield higher ratios than multiple threads. All Ever-power. worm gear models can be found with either left or right hands threads. Ever-Power. worm equipment sets can be found with Single, Double, Triple and Qua-druple Threads.
SAFETY PROVISION: Worm gearing custom worm gear shouldn’t be used seeing that a locking mechanism to carry large weights where reversing actions could cause harm or damage. In applications where potential damage is non-existent and self-locking is preferred against backward rotation after that use of an individual thread worm with a minimal helix angle immediately locks the worm equipment drive against backward rotation.
