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

Capable of handling 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 since 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 for example oil & gas, primary and secondary metal processing, industrial food production, metal slicing and forming machinery, wastewater treatment, extrusion apparatus, among others.

Cycloidal advantages over various other styles of gearing;

The Ever-Power 3000 and our related products that utilize cycloidal gearing technology deliver the most robust solution in the most compact footprint. The primary power train is made up of an eccentric roller bearing that drives a wheel around a couple of inner pins, keeping the decrease 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 design introduces compression forces, instead of those shear forces that could can be found with an involute equipment mesh. That provides several performance benefits such as high shock load capacity (>500% of rating), minimal friction and use, lower mechanical service elements, among many others. The cycloidal style also has a sizable output shaft bearing span, which gives 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 may be the input and its rotation causes an eccentric movement in the yellow cycloidal disk. The cycloidal disk is targeted at a stationary outer ring, represented in the animation by the outer band of grey segments. Its motion is transferred to the purple result shaft via rollers or pins that user interface to the holes in the disk. Like planetary gearing, the output shaft rotates in the contrary direction to the input shaft. Because the individual parts are well-suitable to 3D printing, this opens the door to easily prototyping custom styles and gearing ratios.
