Custom Worm Gears

Worm Gears are best angle drives providing large quickness ratios on comparatively brief center distances from 1/4” to 11”. When properly mounted and lubricated they function as quietist and smoothest working type of gearing. Due to the high ratios possible with worm gearing, optimum speed reduction can 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 big level on the helix position of the worm. Multiple thread worms and gears with higher helix position prove 25% to 50% better than solitary thread worms. The mesh or engagement of worms with worm gears generates a custom worm gear sliding action leading to considerable friction and greater loss of efficiency beyond other styles of gearing. The use of hardened and surface worm swith bronze worm gears increases efficiency.

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

RATIOS of worm gear sets are determined by dividing the number of teeth in the gear 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 hand threads. Ever-Power. worm equipment sets can be found with Single, Double, Triple and Qua-druple Threads.

Basic safety PROVISION: Worm gearing should not be used seeing that a locking mechanism to carry heavy weights where reversing action could cause harm or damage. In applications where potential damage is non-existent and self-locking is preferred against backward rotation then use of an individual thread worm with a minimal helix angle instantly locks the worm equipment travel against backward rotation.
