Custom Worm Gears
Worm Gears are right angle drives providing large speed ratios on comparatively brief center distances from 1/4” to 11”. When properly installed 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 can be accomplished in 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 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 produces a sliding action causing considerable friction and better loss of efficiency beyond other types of gearing. The use of hardened and ground worm swith bronze worm gears boosts efficiency.
LUBRICATION is an essential factor to boost effectiveness in worm gearing. Worm gear action generates considerable high temperature, decreasing efficiency. The quantity of power transmitted at a given temperature boosts as the performance of the gearing increases. Proper lubrication enhances efficiency by reducing friction and temperature.
RATIOS of worm equipment sets are determined by dividing the amount of teeth in the gear 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 still left or right hand threads. Ever-Power. worm equipment sets can be found with One, Double, custom worm gear china Triple and Qua-druple Threads.
Security PROVISION: Worm gearing should not be used as a locking mechanism to carry heavy weights where reversing actions can cause harm or injury. In applications where potential harm 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 gear drive against backward rotation.
