IDEA NOTE Uses a rotary actuator as a drive source.
The reason for the employment of a rotary actuator is that space-saving is required due to a restriction on the upward stroke and the movement needs to be slow.
IDEA NOTE Prevention of oil splash
The actuator and other parts are located below the workpiece transfer face.
A cover is installed around the thrust bearing.
IDEA NOTE Absorbs misalignment between shafts.
As a measure against misalignment between the rotary actuator shaft and the lead screw shaft,
only a thrust bearing is installed, without installing a radial bearing or an angular contact bearing.
A double disc type coupling is employed.
