The lowest cost and shortest delivery schedules are usually achieved through the application of standard worm and gear sets. In addition to using normal shaft middle distances, ratios, and bearing mounting parts, designs will include normal bores, flanges, and bolt circles where likely. Since the utilization of nonstandard hubs isn’t uncommon to the worm equipment industry, Ever-power offers this by having a flanged rim design available for mounting on any adaptable middle.
Our metric worm gears come in pairs with worm shafts or worms. They are constructed of stainless steel, steel, brass or plastic-type materials. Available in different sizes ranging from module 1 to module 5.
Ever-power manufactures worm equipment sets, which are made up of a worm and worm wheel, for employ in many different industries including aerospace and military instrumentation, medical, teeth, coal and oil exploration, robotics, optical and industrial settings. Our precision worm gear sets can be manufactured to meet the latest AGMA/ISO specs up to the equivalent of AGMA Q14 per AGMA 390.03.
