Custom Worm Gears
Worm Gears are right angle drives providing large quickness ratios on comparatively short center distances from 1/4” to 11”. When properly installed and lubricated they function as the quietist and smoothest operating type of gearing. Due to 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 are powered by nonintersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a big level on the helix angle of the worm. custom worm gear china 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 leading to considerable friction and better loss of efficiency beyond other types of gearing. The utilization of hardened and floor worm 
swith bronze worm gears boosts efficiency.
LUBRICATION can be an essential factor to boost effectiveness 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 boosts. Proper lubrication enhances efficiency by reducing friction and heat.
RATIOS of worm gear sets are determined by dividing the amount of teeth in the apparatus by the number of threads. Thus solitary threads yield higher ratios than multiple threads. All Ever-power. worm gear pieces are available with either still left or right hand threads. Ever-Power. worm gear sets can be found with One, Double, Triple and Qua-druple Threads.
SAFETY PROVISION: Worm gearing should not be used seeing that a locking mechanism to hold heavy weights where reversing actions can cause harm or damage. In applications where potential damage 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 equipment drive against backward rotation.
