Custom Worm Gears
Worm Gears are best angle drives providing large swiftness ratios on comparatively short center distances from 1/4” to 11”. When properly mounted and lubricated they function as the quietist and smoothest operating type of gearing. Due to the high ratios possible with worm gearing, maximum speed reduction can be accomplished in much 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 gear drives depends to a sizable 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 creates a sliding action causing considerable friction and greater loss of efficiency beyond other types of gearing. The usage of hardened and ground worm swith bronze worm gears raises efficiency.
LUBRICATION can be an essential factor to boost custom worm gear performance in worm gearing. Worm equipment 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 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 left or right hand threads. Ever-Power. worm equipment sets are offered with One, Double, Triple and Qua-druple Threads.
Basic safety PROVISION: Worm gearing should not be used seeing that a locking mechanism to hold heavy weights where reversing action can cause harm or damage. In applications where potential damage is non-existent and self-locking is desired against backward rotation then use of an individual thread worm with a minimal helix angle automatically locks the worm gear get against backward rotation.
