Custom Worm Gears

Worm Gears are right angle drives providing large speed ratios on comparatively short center distances from 1/4” to 11”. When properly installed and lubricated they function as the quietist and smoothest working type of gearing. Due to the high ratios feasible with worm gearing, maximum 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 large extent 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 generates a sliding action leading to considerable friction and greater loss of efficiency beyond other types of gearing. The utilization of hardened and surface worm swith bronze worm gears increases 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 raises as the performance of the gearing custom worm gear china boosts. Proper lubrication enhances efficiency by reducing friction and heat.

RATIOS of worm equipment 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 sets can be found with either still left or right hand threads. Ever-Power. worm gear sets can be found with Single, Double, Triple and Qua-druple Threads.

Security PROVISION: Worm gearing should not be used as 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 desired against backward rotation then use of a single thread worm with a minimal helix angle immediately locks the worm equipment drive against backward rotation.
