TCG Ring Internal-gear type(Full Ring),UGF&CPA/UFC&CPC Series

The combination between the cam ring formed by the trochoidal tooth profile and the roller pinion enables Zero-Backlash, high-precision positioning, and light rotational transmission.

Its rotating cam ring and roller pinion are ready to meet new design needs. This device's cam ring also has a wide inner diameter and can be effectively used to unitize hollow structures.

Technical Information
TCG Ring Internal Gear

Highlights

Zero-Backlash

The teeth always mesh via two or three portions and eliminate backlash when rotated in one or another direction.

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.
