Custom Worm Gears
Worm Gears are ideal angle drives providing large velocity ratios on comparatively short center distances from 1/4” to 11”. When properly mounted and lubricated they function as quietist and smoothest running type of gearing. Because of the high ratios feasible with worm gearing, optimum speed reduction could 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 sizable extent on the helix angle of the worm. Multiple thread worms and gears with higher helix position prove 25% to 50% better than solitary thread worms. The mesh or engagement of worms with worm gears produces a sliding action causing considerable friction and higher lack of efficiency beyond other types of gearing. The utilization of hardened and custom worm gear china ground worm swith bronze worm gears raises efficiency.
LUBRICATION is an essential factor to boost performance in worm gearing. Worm gear action generates considerable temperature, decreasing efficiency. The amount of power transmitted at a given temperature increases as the effectiveness of the gearing raises. Proper lubrication enhances performance by reducing friction and heat.
RATIOS of worm gear sets are determined by dividing the number of teeth in the apparatus by the number of threads. Thus one threads yield higher ratios than multiple threads. All Ever-power. worm gear models can be found with either still left or right hands threads. Ever-Power. worm gear sets are offered with Solitary, Double, Triple and Qua-druple Threads.
Protection PROVISION: Worm gearing should not be used as a locking mechanism to hold heavy weights where reversing action could cause harm or injury. In applications where potential harm is nonexistent and self-locking is preferred against backward rotation after that use of a single thread worm with a low helix angle instantly locks the worm equipment get against backward rotation.
