As with our conventional external gears, shaft options include toned or hex shafts, and we use gear cutting strategies from broaching to hobbing, depending on design options and end-consumer requirements. We are able to also heat treat inner gears via carburizing, flame induction, or nitriding.

Ever-Power full line of gear manufacturing providers includes internal gears, in addition to our collection of conventional, external gears. Internal gears, with teeth located on the inside instead of the outside of the apparatus, are used in all industrial sectors, from military/govt to electronics and chemical applications. We also serve clients in the medical, automotive, biotechnology, and packaging sectors. Our internal gears could be produced in diameters up to 42″, with a maximum diametrical pitch of 2.5, and a maximum module of 10.

Custom Internal Gears

We substantiate our quality to you on every equipment we manufacture by e-mail through the modern On-table Inspection and Software Technology offered all over the world.

Decreased sliding action because of internal gear tooth configuration
Reduced sliding means less friction and less tooth wear
Internal gear in some applications eliminates dependence on an idler gear
Internal gears could be operated in a set position or a free rotating with pinion fixed
Ever-Power internal gear grinding technology “exceeds that of any of our competitors” and allows us to manufacture the biggest Pinions of any Pitch and Face Widths of up to 80″. This technology also gives us Inspection Features for Lead, Pitch, Profile, & Runout, on Internal Gears up to 240″ Diameter. The precision design and manufacture of our internal gears results in smoother operation and better performance.
