 Circular vibration generated in the radial direction of the thread surface corresponding to the axis of the screw shaft support part.
This item includes the influence of the full vibration of the screw axis in the back-radial direction of item (8), so sometimes corrections must be made.
The radial direction of the component mounting portion corresponding to the axis of the support portion of the screw shaft vibrates circumferentially.
The end face of the support part corresponding to the axis of the support part of the screw shaft must be at a right angle.
The axis of the screw shaft corresponds to the right angle of the base end face of the nut or the flange mounting surface.
The axis of the screw shaft corresponds to a circular vibration in the radial direction around the outer periphery of the nut.
Full vibration of the screw shaft.
