Much like our conventional exterior gears, shaft choices include smooth 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 solutions includes internal gears, in addition to our collection of conventional, external gears. Internal gears, with teeth on the inside as opposed to the outside of the apparatus, are used in all industries, from military/federal government to electronics and chemical substance applications. We also provide customers in the medical, automotive, biotechnology, and packaging industries. Our internal gears can be produced in diameters up to 42″, with a optimum diametrical pitch of 2.5, and a maximum module of 10.

Custom Internal Gears

We substantiate our quality to you on every equipment we produce by e-mail through the most modern On-board Inspection and Software Technology obtainable anywhere in the world.

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