Custom Worm Gears
Worm Gears are best angle drives providing large swiftness ratios on comparatively brief center distances from 1/4” to 11”. When properly mounted 
and lubricated they function as the quietist and smoothest running type of gearing. Because of the high ratios feasible with worm gearing, maximum speed reduction could 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 gear 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 causing considerable friction and higher loss of efficiency beyond other types of gearing. The usage of hardened and floor worm swith bronze worm gears raises efficiency.
LUBRICATION is an essential factor to improve performance in worm gearing. Worm gear action generates considerable high temperature, 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 temperature.
RATIOS of worm gear sets are determined by dividing the number of teeth in the apparatus by the amount of threads. Thus single threads yield higher ratios than multiple threads. All Ever-power. worm gear units can be found with custom worm gear china either left or right hands threads. Ever-Power. worm equipment sets can be found with One, Double, Triple and Qua-druple Threads.
Basic safety PROVISION: Worm gearing should not be used seeing that 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 a single thread worm with a minimal helix angle immediately locks the worm equipment get against backward rotation.
