Worm gears are typically used when large equipment reductions are needed; it is common for worm gears to have got reductions of 25:1 and higher. When engineered correctly, worm gears provide constant, dependable, smooth and peaceful running gearing.
We produce gears for many industries, from small to huge, in a variety of components and size ranges. Avon Gear and Engineering uses state-of-the-art technology, not only in the manufacturing process but in monitoring quality as well. Our engineers understand that the end result is only as effective as the blank they start with, therefore we machine our own blanks to preserve the best quality standards.
Ever-Power Gear and Engineering specializes in precision lower worm gears for applications requiring high-ratio speed decrease in a limited space. Our gears and worms are built and produced to exacting standards and specifications. From typical to unconventional, easy to complex, Avon is normally capable of producing the best engineered solution for any application.
Ever-Power gets the full production capacity of most types of gears. Proud to supply 
worm and worm gear sets for customers in all industries. The maximum diameter of the worm gear can be made 120″, as the diameter of the worm equipment could be up to 10″. For gears, we are able to make tooth and size ratios of up to 1.5 DP and 16 modules. With instant production and scheduling features, we can use our customers to look for the most efficient and useful way to manufacture and transfer worm gears and worm pieces.
Our material options include brass, bronze, stainless and grey cast iron. Our complete production capabilities consist of forging, die casting, centrifugal casting and equipment and worm trimming by hobbing, broaching, milling or cutting. We may also surface finish the machining of the worm gear and the worm by honing, grinding, shaving or sanding.
