Custom Worm Gears

Worm Gears are ideal angle drives providing large speed ratios on comparatively brief center distances from 1/4” to 11”. When custom worm gear china correctly mounted and lubricated they function as 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 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 degree on the helix position of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% better 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 use of hardened and surface worm swith bronze worm gears boosts efficiency.

LUBRICATION can be an essential factor to improve performance in worm gearing. Worm equipment action generates considerable warmth, decreasing efficiency. The quantity of power transmitted at a given temperature boosts as the performance of the gearing boosts. Proper lubrication enhances performance 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 one threads yield higher ratios than multiple threads. All Ever-power. worm gear sets are available with either still left or right hands threads. Ever-Power. worm equipment sets can be found with Solitary, Double, Triple and Qua-druple Threads.

Protection PROVISION: Worm gearing should not be used as a locking mechanism to carry large weights where reversing action could 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 low helix angle instantly locks the worm equipment drive against backward rotation.
