As with our conventional exterior gears, shaft options include toned or hex shafts, and we use gear cutting methods from broaching to hobbing, depending on design options and end-user requirements. We can 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 collection of conventional, external gears. Internal gears, with teeth located on the inside as opposed to the outside of the gear, are used in all industrial sectors, from military/govt to electronics and chemical applications. We also provide clients in the medical, auto, biotechnology, and packaging industries. Our internal gears can 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 to you on every gear we produce by e-mail through the modern On-plank Inspection and Software Technology obtainable anywhere in the world.
Decreased sliding action because of internal gear tooth configuration
Reduced 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 gear grinding technology “exceeds that of any of our competition” and allows us to manufacture the Largest 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 design and manufacture of our internal gears results in smoother procedure and better performance.
