Custom Worm Gears
Worm Gears are ideal angle drives providing large speed ratios on comparatively short center distances from 1/4” to 11”. When correctly installed and lubricated they function as the quietist and smoothest operating type of gearing. Due to the high ratios possible with worm gearing, optimum speed reduction can be accomplished in much less space than many other types of gearing. Worm and worm gears are powered by non-intersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a large level on the helix position 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 creates a sliding action leading to considerable friction and better lack of efficiency beyond other styles of gearing. The use of hardened and surface worm swith bronze worm gears boosts efficiency.
LUBRICATION can be an essential factor to improve efficiency in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The amount of power transmitted at confirmed temperature increases as the effectiveness of the gearing raises. Proper lubrication enhances effectiveness by reducing friction and high temperature.
RATIOS of worm equipment sets are determined by dividing the number of teeth in the gear by the number of threads. Thus solitary threads yield higher ratios than multiple threads. All Ever-power. worm gear pieces are available with either still left or right hands threads. Ever-Power. worm equipment sets are offered with Solitary, Double, Triple and Qua-druple Threads.
Security PROVISION: Worm gearing should not be used as a locking mechanism to hold large weights where reversing actions can cause harm or damage. In custom worm gear china applications where potential damage is non-existent and self-locking is preferred against backward rotation then use of an individual thread worm with a low helix angle instantly locks the worm gear drive against backward rotation.
