Custom Worm Gears

Worm Gears are ideal angle drives providing huge swiftness custom worm gear ratios on comparatively brief center distances from 1/4” to 11”. When properly mounted and lubricated they function as quietist and smoothest working type of gearing. Due to the high ratios feasible with worm gearing, maximum speed reduction can be accomplished in less space than a great many other types of gearing. Worm and worm gears are powered by nonintersecting shafts at 90° angles.

EFFICIENCY of worm equipment drives depends to a huge extent on the helix angle of the worm. Multiple thread worms and gears with higher helix position prove 25% to 50% better than single 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 types of gearing. The use of hardened and ground worm swith bronze worm gears increases efficiency.

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

RATIOS of worm gear sets are determined by dividing the number of teeth in the apparatus by the number of threads. Thus one threads yield higher ratios than multiple threads. All Ever-power. worm gear units can be found with either left or right hand threads. Ever-Power. worm gear sets are offered with One, Double, Triple and Qua-druple Threads.

Security PROVISION: Worm gearing shouldn’t be used seeing that a locking mechanism to carry heavy weights where reversing action could cause harm or damage. In applications where potential damage is nonexistent and self-locking is desired against backward rotation then use of a single thread worm with a minimal helix angle instantly locks the worm equipment travel against backward rotation.
