FEATURES AND BENEFITS
Ever-Power develops and manufactures cycloidal gear boxes to round off the product portfolio. In drive technology, especially in neuro-scientific device machinery, automation and robotics, these compact designed, high transmitting precision equipment boxes are used specifically to meet the highest demands for stiffness, overall performance and efficiency. In addition to the constantly extended standard range, these cycloidal precision equipment boxes could 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 electric motor for longer service life
Just ridiculously rugged as all get-out
The overall 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 commercial marketplace, and it is a perfect match for applications in weighty industry such as oil & gas, major and secondary metal processing, commercial food production, metal reducing and forming machinery, wastewater treatment, extrusion gear, among others.

Cycloidal advantages over additional styles of gearing;

The Ever-Power 3000 and our related products that use cycloidal gearing technology deliver the most robust solution in the many 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 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 stage of contact. This design introduces compression forces, rather than those shear forces that could can be found with an involute equipment mesh. That provides a number of efficiency benefits such as high shock load capability (>500% of ranking), minimal friction and put on, lower mechanical service elements, among numerous others. The cycloidal style also has a sizable output shaft bearing span, 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 image demonstrated, the green shaft is the input and its own rotation causes an eccentric motion in the yellowish cycloidal disk. The cycloidal disk is certainly geared to a stationary outer ring, represented in the computer animation by the outer ring of grey segments. Its motion is used in the purple result shaft via rollers or pins that interface to the holes in the disk. Like planetary gearing, the output shaft rotates in the opposite direction to the input shaft. Because the person parts are well-appropriate to 3D printing, this opens the door to easily prototyping customized designs and gearing ratios.
