The lowest cost and shortest delivery schedules are usually achieved through the use of standard worm and gear sets. In addition to using normal shaft centre distances, ratios, and bearing mounting parts, designs will include typical bores, flanges, and bolt circles where possible. Since the use of nonstandard hubs isn’t uncommon to the worm equipment industry, Ever-power offers this by having a flanged rim style available for installation on any adaptable middle.
Our metric worm gears come in pairs with worm shafts or perhaps worms. They are constructed of stainless steel, metal, brass or plastic-type materials. Available in several 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 work with in a variety of industries including aerospace and military instrumentation, medical, dental, coal and oil exploration, robotics, optical and professional regulates. Our precision worm gear sets can be manufactured to meet the latest AGMA/ISO technical specs up to the equivalent of AGMA Q14 per AGMA 390.03.
