Custom Worm Gears

Worm Gears are right angle drives providing large quickness ratios on comparatively brief center distances from 1/4” to 11”. When correctly mounted and lubricated they function as the quietist and smoothest working type of gearing. Due to the high ratios possible with worm gearing, optimum speed reduction could be accomplished in less space than a great many other types of gearing. Worm and worm gears operate on nonintersecting shafts at 90° angles.

EFFICIENCY of worm equipment drives depends to a huge level on the helix position of the worm. Multiple custom worm gear thread worms and gears with higher helix position prove 25% to 50% more efficient than one thread worms. The mesh or engagement of worms with worm gears produces a sliding action causing considerable friction and better lack of efficiency beyond other styles of gearing. The use of hardened and ground worm swith bronze worm gears increases efficiency.

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

RATIOS of worm equipment sets are dependant on dividing the amount of teeth in the gear by the amount of threads. Thus solitary 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 gear sets are offered with Single, Double, Triple and Qua-druple Threads.

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