TCG Ring(Circular Arc Ring), RGD&CPA / RDC&CPC series
A circular arc ring-type cam ring with a trochoidal tooth profile. Manufacturing the ring in circular arcs makes it possible to accommodate an infinite radius with the minimum space required, realizing large-diameter hollow shapes.
Its combination with a roller pinion realizes motion transmission via complete rolling, enabling highly accurate positioning and light rotational-fluctuation motions with Zero-Backlash.

Highlights
Zero-Backlash
The teeth always mesh via two or three portions and eliminate backlash when rotated in one or another direction.
Circular Arc Rings and Large Diameter
Ring diameter up to tens of meters can be realized by combining the circular arc rings or can use only the necessary degrees.
High Accuracy
The combination of cam gear and roller pinion makes a positioning accuracy and feeding accuracy (rotation-linearity ratio) as nearly as the ball-screw.
Low noise, Low vibration
Rollers of Pinion supported by bearings roll smoothly on the trochoid gear. Thereby tooth striking noise, rotating noise and also vibration are reduced.
Low dust
Due to the smooth rotation, the structure dispenses with a least amount of heat and dust generated and cope with a clean room operation.
No need for applying the lubricant
Combined with the TCG lubrication supply system TLS, No need for applying the lubricant, completely maintenance-free are realized.
