Custom Worm Gears

Worm Gears are ideal angle drives providing large rate ratios on comparatively short center distances from 1/4” to 11”. When correctly mounted and lubricated they function as quietist and smoothest working type of gearing. Due to the high ratios possible 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 gear drives depends to a sizable level 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 creates a sliding action causing considerable friction and greater lack of efficiency beyond other types of gearing. The usage of hardened and floor worm swith bronze worm gears increases efficiency.

LUBRICATION is an essential factor to boost performance in worm gearing. Worm gear action generates considerable temperature, decreasing efficiency. The quantity of power transmitted at confirmed temperature boosts as the performance of the gearing raises. Proper lubrication enhances efficiency by reducing friction and temperature.

RATIOS of worm equipment sets are custom worm gear dependant on dividing the number of teeth in the gear by the number of threads. Thus single threads yield higher ratios than multiple threads. All Ever-power. worm gear units are available with either still left or right hands threads. Ever-Power. worm equipment sets can be found with Single, Double, Triple and Qua-druple Threads.

Security PROVISION: Worm gearing should not be used while a locking mechanism to hold large weights where reversing action could cause harm or damage. In applications where potential damage is non-existent 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 travel against backward rotation.
