FEATURES AND BENEFITS
Ever-Power develops and manufactures cycloidal equipment boxes to round off the merchandise portfolio. In drive technology, especially in neuro-scientific tool machinery, automation and robotics, these small designed, high transmission 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 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 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 requires minimal maintenance following installation. The Ever-Power may be the most dependable reducer in the commercial marketplace, and it is a perfect match for applications in heavy industry such as oil & gas, major and secondary metal processing, commercial food production, metal trimming and forming machinery, wastewater treatment, extrusion gear, among cycloidal gearbox others.

Cycloidal advantages over various other styles of gearing;

The Ever-Power 3000 and our related products that make use of cycloidal gearing technology deliver the the majority of robust solution in the many 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 includes a curved tooth profile instead of the more traditional involute tooth profile, which gets rid of 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 equipment mesh. That provides a number of functionality benefits such as high shock load capability (>500% of rating), minimal friction and wear, lower mechanical service factors, among many others. The cycloidal style 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 demonstrated, the green shaft is the input and its own rotation causes an eccentric movement in the yellow cycloidal disk. The cycloidal disk is definitely geared to a stationary outer band, represented in the computer animation by the outer ring 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 result shaft rotates in the opposite direction to the input shaft. Because the person parts are well-appropriate to 3D printing, this opens the entranceway to easily prototyping customized designs and gearing ratios.
