The lowest cost and shortest delivery schedules are normally achieved through the usage of standard worm and gear sets. In addition to using common shaft centre distances, ratios, and bearing installation parts, designs should include regular bores, flanges, and bolt circles where feasible. Since the utilization of nonstandard hubs is not uncommon to the worm equipment industry, Ever-power offers this by having a flanged rim design available for installation on any adaptable centre.
Our metric worm gears can be found in pairs with worm shafts or worms. They are made of stainless steel, steel, brass or plastic materials. Available in various sizes which range from module 1 to module 5.
Ever-power manufactures worm equipment sets, which are comprised of a worm and worm wheel, for use in a variety of industries including aerospace and military instrumentation, medical, oral, oil and gas exploration, robotics, optical and industrial regulates. Our precision worm gear sets can be manufactured to meet the latest AGMA/ISO features up to the same as AGMA Q14 per AGMA 390.03.
