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.
Technical InformationHighlights
-
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.
