FEATURES AND BENEFITS
Ever-Power develops and manufactures cycloidal equipment boxes to round off the merchandise portfolio. In drive technology, especially in neuro-scientific device machinery, automation and robotics, these small designed, high transmitting precision equipment boxes are used especially to meet the best demands for stiffness, overall performance and efficiency. In addition to the constantly extended regular range, these cycloidal precision equipment boxes can be adapted to consumer requirements upon request.

Able to handle larger “shock” loads (>500%) of rating in comparison to worm, helical, etc.
High reduction ratios and torque density in a concise 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 entire Ever-Power design proves to be extremely durable, and it needs minimal maintenance following installation. The Ever-Power is the most reliable reducer in the industrial marketplace, in fact it is a perfect fit for applications in weighty industry such as oil & gas, major and secondary metal processing, commercial food production, metal cutting and forming machinery, wastewater treatment, extrusion devices, among others.

Cycloidal advantages over other styles of gearing;

The Ever-Power 3000 and our related products that use cycloidal gearing technology deliver the the majority of robust solution in the most compact footprint. The main power train is comprised of an eccentric roller bearing that drives a wheel around a couple 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 eliminates shear forces at any point of contact. This style introduces compression forces, instead of those shear forces that could can be found with an involute gear mesh. That provides numerous efficiency benefits such as high shock load capacity (>500% of ranking), minimal friction and use, lower mechanical service factors, among many others. The cycloidal design also has a sizable output shaft bearing period, which gives exceptional overhung load features without requiring any additional expensive components.

A cycloidal drive has some similarities to both planetary gearing and strain-wave gears. In the picture shown, the green shaft is the input and its rotation causes an eccentric motion in the yellow cycloidal disk. The cycloidal disk is geared to a stationary outer band, represented in the animation by the outer ring of grey segments. Its movement is used in the purple output shaft via rollers or pins that user interface to the holes in the disk. Like planetary gearing, the result shaft rotates in the opposite direction to the insight shaft. Because the individual parts are well-appropriate to 3D printing, this opens the entranceway to easily prototyping custom designs and gearing ratios.
