Custom Worm Gears

Worm Gears are ideal angle drives providing large velocity ratios on comparatively brief center distances from 1/4” to 11”. When correctly mounted and lubricated they function as quietist and smoothest running type of gearing. Due to the high ratios possible with worm gearing, optimum speed reduction could be accomplished in much less space than many other types of gearing. Worm and worm gears operate on 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 creates a sliding action causing considerable friction and better loss of efficiency beyond other types of gearing. The use of hardened and surface worm swith bronze worm gears raises efficiency.

LUBRICATION is an essential factor to boost effectiveness in worm gearing. Worm gear action generates considerable high temperature, decreasing efficiency. The amount of power transmitted at confirmed temperature boosts as the effectiveness of the gearing 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 gear by the amount of threads. Thus one threads yield higher ratios than multiple threads. All Ever-power. worm gear units can be found with either still left or right hands threads. Ever-Power. worm gear sets can be found with One, 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 injury. In custom worm gear applications where potential damage is non-existent and self-locking is preferred against backward rotation after that use of an individual thread worm with a low helix angle instantly locks the worm equipment get against backward rotation.
