Custom Worm Gears
Worm Gears are right angle drives providing large quickness ratios on comparatively brief center distances from 1/4” to 11”. When custom worm gear china correctly mounted and lubricated they function as quietist and smoothest running type of gearing. Due to the high ratios 
feasible with worm gearing, maximum speed reduction could be accomplished in much less space than a great many other types of gearing. Worm and worm gears operate on 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% more efficient than single thread worms. The mesh or engagement of worms with worm gears creates a sliding action causing considerable friction and better loss of efficiency beyond other styles of gearing. The usage of hardened and floor worm swith bronze worm gears raises efficiency.
LUBRICATION can be an essential factor to boost performance in worm gearing. Worm equipment action generates considerable temperature, decreasing efficiency. The quantity of power transmitted at a given temperature boosts as the effectiveness of the gearing boosts. Proper lubrication enhances efficiency by reducing friction and high temperature.
RATIOS of worm equipment sets are dependant on 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 models can be found with either left or right hands threads. Ever-Power. worm gear sets can be found with One, Double, Triple and Qua-druple Threads.
SAFETY PROVISION: Worm gearing should not be used seeing that a locking mechanism to carry large weights where reversing action could cause harm or injury. In applications where potential damage is nonexistent and self-locking is desired against backward rotation after that use of an individual thread worm with a minimal helix angle automatically locks the worm equipment get against backward rotation.
