Internal Gears

Much like our conventional external gears, shaft options include smooth or hex shafts, and we make use of gear cutting methods from broaching to hobbing, depending on design choices and end-consumer requirements. We can also heat treat inner gears via carburizing, flame induction, or nitriding.

Ever-Power full line of gear manufacturing services includes internal gears, in addition to our selection of conventional, exterior gears. Internal gears, with teeth located on the inside as opposed to the outside of the gear, are used in all sectors, from military/government to electronics and chemical substance applications. We also serve clients in the medical, auto, biotechnology, and packaging sectors. Our internal gears can be stated in diameters up to 42″, with a maximum diametrical pitch of 2.5, and a maximum module of 10.

Custom Internal Gears

We substantiate our quality to you on every gear we manufacture by e-mail through the modern On-board Inspection and Software Technology offered all over 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 need for an idler gear
Internal gears may be operated in a fixed position or a free of charge rotating with pinion fixed
Ever-Power internal equipment grinding technology “exceeds that of any of our rivals” and allows us to manufacture the Largest Pinions of any Pitch and Encounter 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 results in smoother procedure and better performance.
