Internal Gears

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

Ever-Power full line of gear manufacturing solutions includes internal gears, in addition to our collection of conventional, external gears. Internal gears, with teeth located on the inside as opposed to the outside of the apparatus, are used in all industries, from military/authorities to electronics and chemical applications. We also serve customers in the medical, auto, biotechnology, and packaging industries. Our internal gears could 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 for you on every gear we produce 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 need for an idler gear
Internal gears may be operated in a set position or a free rotating with pinion fixed
Ever-Power internal equipment grinding technology “exceeds that of any of our rivals” and allows us to manufacture the biggest Pinions of any Pitch and Encounter 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 procedure and better performance.
