As with our conventional exterior gears, shaft choices include flat or hex shafts, and we use gear cutting methods from broaching to hobbing, depending on design options and end-user requirements. We are able to also heat treat internal gears via carburizing, flame induction, or nitriding.

Ever-Power full line of gear manufacturing providers includes internal gears, in addition to our selection of conventional, exterior gears. Internal gears, with teeth on the inside as opposed to the outside of the apparatus, are found in all sectors, from military/govt to electronics and chemical substance applications. We also provide clients in the medical, automotive, biotechnology, and packaging industries. Our internal gears could be produced in diameters up to 42″, with a maximum diametrical pitch of 2.5, and a optimum module of 10.

Custom Internal Gears

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

Decreased sliding action due to internal gear tooth configuration
Reduced sliding means less friction and less tooth wear
Internal gear in a few applications eliminates dependence on an idler gear
Internal gears may be operated in a fixed 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 as high as 80″. This technology also gives us Inspection Features for Lead, Pitch, Profile, & Runout, on Internal Gears up to 240″ Size. The precision design and manufacture of our internal gears results in smoother procedure and better performance.
