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

Able to handle larger “shock” loads (>500%) of rating compared 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 engine 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 may be the most reliable reducer in the commercial marketplace, in fact it is a perfect fit for applications in weighty industry such as oil & gas, primary and secondary metal processing, commercial food production, metal cutting and forming machinery, wastewater treatment, extrusion devices, among others.

Cycloidal advantages over additional styles of gearing;

The Ever-Power 3000 and our related products that make use of cycloidal gearing technology deliver the many robust solution in the many compact footprint. The main power train is comprised of an eccentric roller bearing that drives a wheel around a set of inner pins, keeping the decrease high and the rotational inertia low. The wheel includes a curved tooth profile instead of the more traditional involute tooth profile, which removes shear forces at any stage of contact. This style introduces compression forces, instead of those shear forces that could exist with an involute equipment mesh. That provides several overall performance benefits such as for example high shock load capability (>500% of ranking), minimal friction and put on, lower mechanical service factors, among many others. The cycloidal design also has a sizable output shaft bearing span, which provides exceptional overhung load capabilities without requiring any extra expensive components.

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