Custom Worm Gears
Worm Gears are best angle drives providing huge speed ratios on comparatively brief center distances from 1/4” to 11”. When properly installed and lubricated they function as quietist and smoothest operating type of gearing. Due to the high ratios possible with worm gearing, maximum speed reduction can be accomplished in less space than 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 angle prove 25% to 50% more efficient than solitary thread worms. The mesh or engagement of worms with worm gears produces a sliding action leading to considerable friction and greater lack of efficiency beyond other styles of gearing. The usage of hardened and ground worm swith bronze worm gears raises efficiency.
LUBRICATION can be an essential factor to improve efficiency in worm gearing. Worm gear action generates considerable heat, decreasing efficiency. The amount of power transmitted at confirmed temperature boosts as the performance of the gearing raises. Proper lubrication enhances performance 
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 one 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 equipment sets are offered with Solitary, Double, Triple and Qua-druple Threads.
Basic safety PROVISION: Worm gearing shouldn’t be used as a locking mechanism to carry heavy weights where reversing actions could cause harm or damage. In applications where potential damage is non-existent and self-locking is desired against backward custom worm gear china rotation then use of a single thread worm with a low helix angle automatically locks the worm equipment travel against backward rotation.
