RE series - 3

In FA equipment, motion control using servo systems is a crucial element which greatly affects equipment performance. Naturally, equipment specifications and performance are designed assuming that the expected motion is attained, but if there are factors such as backlash, insufficient rigidity or control instability in the motion control section, then output motion will deviate from input control commands, and it will be difficult to attain the expected performance. With the RollerDrive RE Series, a servomotor is mechanically reduced while maintaining powerful torque, rigidity and...

The RollerDrive reducer is optimally designed for high accuracy reducion. By using a roller gear mechanism, we offer one of the very best motion control mechanisms. The roller gear mechanism consists of main parts such as an input shaft cam (roller gear cam), a cam follower and a turret supporting the cam follower. The cam is screw shaped, and the cam follower displaces the cam relative to the rotation of the cam, thus rotating the turret. The cross-section of the roller gear cam is wedge-shaped and this wedge completely eliminates any backslash taking up the space between the two cam...
