Custom Worm

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

EFFICIENCY of drives depends to a big level on the helix angle of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% more efficient than one thread worms. The mesh or engagement of worms with worm gears creates a sliding action causing considerable friction and higher loss of efficiency beyond other styles of gearing. The usage of hardened and surface worm swith bronze worm gears increases efficiency.

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

RATIOS of worm gear sets are dependant on 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 models are available with either left or right hand threads. Ever-Power. worm gear sets are offered with Solitary, Double, Triple and Qua-druple Threads.

SAFETY custom worm gear custom worm gear56433688062PROVISION: Worm gearing shouldn't be used as a locking mechanism to carry heavy weights where reversing actions could cause harm or damage. In applications where potential harm is nonexistent and self-locking is desired against backward rotation after that use of a single thread worm with a low helix angle automatically locks the worm gear travel against backward rotation.
