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 transmission precision gear boxes are used specifically to meet the best demands for stiffness, functionality and efficiency. In addition to the constantly extended standard range, these cycloidal precision equipment boxes could be adapted to client 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 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 may be the most dependable reducer in the industrial marketplace, in fact it is a perfect fit for applications in heavy industry such as oil & gas, primary and secondary steel processing, industrial food production, metal slicing and forming machinery, wastewater treatment, extrusion equipment, 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 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 stage of contact. This design introduces compression forces, instead of those shear forces that would can be found with an involute equipment mesh. That provides a number of overall performance benefits such as for example high shock load capacity (>500% of rating), minimal friction and put on, lower mechanical service factors, among numerous others. The cycloidal design also has a large output shaft bearing span, which provides exceptional overhung load features without requiring any extra expensive components.

A cycloidal drive has some similarities to both planetary gearing and strain-wave gears. In the image demonstrated, the green shaft is the input and its own rotation causes an eccentric motion in the yellow-colored cycloidal disk. The cycloidal disk is certainly geared to a stationary outer ring, represented in the animation by the outer band of grey segments. Its movement is used in the purple result 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-suitable to 3D printing, this opens the door to easily prototyping customized styles and gearing ratios.
