Inline Cycloidal Gearboxes

Ever-Power-gearboxes EP 3000 Series variants, Ever-Power product family

The Ever-Power 3000 and our related products that utilize cycloidal gearing technology deliver the most robust solution in the most compact footprint. The main power train is comprised of an eccentric roller bearing that drives a wheel around a set of internal pins, keeping the reduction high and the rotational inertia low. The wheel incorporates a curved tooth profile instead of the more traditional involute tooth profile, which removes shear forces at any point of contact. This design introduces compression forces, instead of those shear forces that would exist with an involute gear mesh. That provides a number of performance benefits such as high shock load capacity (>500% of rating), minimal friction and wear, lower mechanical service factors, among many others. The cycloidal design also has a large output shaft bearing span, which provides exceptional overhung load capabilities without requiring any additional expensive components.

Cycloidal advantages over other styles of gearing;

Capable of handling larger “shock” loads (>500%) of rating compared to worm, helical, etc.

High reduction ratios and torque density in a compact dimensional footprint

Exceptional “built-in” overhung load carrying capability

High efficiency (>95%) per reduction stage

Minimal reflected inertia to motor for longer service life

Just ridiculously rugged as all get-out

The overall Ever-Power design proves to be extremely durable, and it requires minimal maintenance following installation. The Ever-Power is the most dependable reducer in the industrial marketplace, and it is a perfect fit for applications in heavy industry such as oil & gas, primary and secondary steel processing, industrial food production, metal cutting and forming machinery, wastewater treatment, extrusion equipment, among others.
