As with our conventional exterior gears, shaft choices include flat or hex shafts, and we make use of gear cutting methods from broaching to hobbing, based on design choices 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, furthermore to our selection of conventional, exterior gears. Internal gears, with teeth located on the inside instead of the outside of the gear, are found in all industrial sectors, from military/federal government to electronics and chemical applications. We also provide customers in the medical, auto, 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 optimum module of 10.

Custom Internal Gears

We substantiate our quality for you on every gear we manufacture by e-mail through the modern On-board Inspection and Software Technology offered anywhere in the world.

Decreased sliding action because of internal gear tooth configuration
Decreased sliding means less friction and less tooth wear
Internal gear in a few applications eliminates need for an idler gear
Internal gears may be operated in a fixed position or a free rotating with pinion fixed
Ever-Power internal equipment grinding technology “exceeds that of some of our competitors” and we can 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″ Size. The precision style and manufacture of our inner gears results in smoother operation and better performance.
