Custom Worm Gears

Worm Gears are right angle drives providing large acceleration ratios on comparatively short center distances from 1/4” to 11”. When properly mounted and lubricated they function as quietist and smoothest operating 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 non-intersecting shafts at 90° angles.

EFFICIENCY of worm gear drives depends to a large extent on the helix position 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 generates a sliding action leading to considerable friction and better lack of efficiency beyond other styles of gearing. The use of hardened and ground worm swith bronze worm gears raises efficiency.

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

RATIOS of worm gear sets are dependant on dividing the number of teeth in the apparatus by the amount of threads. Thus one threads yield higher ratios than multiple threads. All Ever-power. worm gear pieces are available with either still left or right hand threads. Ever-Power. worm gear sets can be found with Single, Double, Triple and Qua-druple Threads.

SAFETY PROVISION: Worm gearing should not be used while a locking mechanism to hold 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 after that use of an individual thread worm with a low helix angle automatically locks the worm gear get against backward rotation.
