Much like our conventional exterior gears, shaft options include flat or hex shafts, and we use gear cutting methods from broaching to hobbing, based on design options and end-consumer requirements. We can also heat treat internal gears via carburizing, flame induction, or nitriding.

Ever-Power full line of gear manufacturing services 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 gear, are found in all industrial sectors, from military/govt to electronics and chemical substance applications. We also provide clients in the medical, auto, biotechnology, and packaging industrial sectors. Our internal gears can be stated 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 most modern On-panel Inspection and Software Technology available 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 a few applications eliminates dependence on an idler gear
Internal gears could be operated in a set position or a free of charge rotating with pinion fixed
Ever-Power internal gear grinding technology “exceeds that of some of our competitors” and allows us to manufacture the Largest 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″ Diameter. The precision design and manufacture of our inner gears outcomes in smoother operation and better performance.
