Custom Worm Gears

Worm Gears are right angle drives providing huge speed ratios on comparatively brief center distances from 1/4” to 11”. When properly mounted and lubricated they function as the quietist and smoothest operating type of gearing. Because of the high ratios feasible with worm gearing, maximum speed reduction could be accomplished in much less space than a great many other types of gearing. Worm and worm gears operate on non-intersecting shafts at 90° angles.

EFFICIENCY of worm equipment drives depends to a large level on the helix position of the worm. Multiple thread worms and gears with higher helix position prove 25% to 50% more efficient than single thread worms. The mesh or engagement of worms with worm gears generates a sliding action causing considerable friction and higher lack of efficiency beyond other types of gearing. The usage of hardened and ground worm swith bronze worm gears increases efficiency.

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

RATIOS of worm gear sets are determined by 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 pieces can be found with either left or right hands threads. Ever-Power. worm gear sets can be found with One, Double, Triple and Qua-druple Threads.

SAFETY PROVISION: Worm gearing shouldn’t be used as a locking mechanism to carry heavy weights where reversing action can cause harm or injury. In applications where potential harm is nonexistent and self-locking is desired against backward rotation after that use of an individual thread worm with a minimal helix angle custom worm gear automatically locks the worm gear travel against backward rotation.
