Abstract: There is provided a surface texture measuring apparatus in which a measurement device is replaced easily and safely.A measurement device is replaceable by attaching and detaching the measurement device to and from a drive mechanism part. The measurement device includes a bracket, and the bracket includes a first connector for transmitting and receiving a signal to and from the measurement device and feeding to the measurement device. The drive mechanism part includes a support frame to which the bracket is detachably attached, and the support frame includes a second connector electrically connected to the first connector. The signal is transmitted and received between the first connector and the second connector, and the first connector is fed from the second connector while the first connector and the second connector are connected. Insertion and removal between the first connector and the second connector to attach and detach the measurement device to and from the drive mechanism part is hot swappable.

Abstract: A surface roughness measuring unit according to the present invention includes a contact pin unit having a contact pin and a displacement detector, the contact pin being provided so as to project and retract through a through-hole of a skid and scanning and moving along a surface of a work piece, the displacement detector detecting displacement of the contact pin in a direction perpendicular to the work piece surface; a driver moving the contact pin unit forward and backward along the surface of the work piece; and a joint coupling the contact pin unit and the driver to a measurement head holder of a coordinate measuring system. The surface roughness measuring unit further includes a contact detector that detects contact of the skid on the surface of the work piece.

Abstract: A measuring probe for measuring a screw groove of a relatively rotatable ball screw includes a stylus having a tip end portion configured to contact the screw groove, a radial-direction displacement mechanism configured to support the stylus so as for the stylus to be displaceable in an X direction toward an axial center of the ball screw, an axial-direction displacement mechanism configured to support the stylus so as for the stylus to be displaceable in an axial direction (Z direction) of the axial center, and sensors configured to detect displacement of the stylus produced by the radial-direction displacement mechanism and the axial-direction displacement mechanism. This enables high-accuracy measurement of a predetermined position of a side surface of a relatively rotatable work.

Abstract: A rotation transmitter includes a first member, a second member, and an intermediate member. The first member is connected to the intermediate member by a first rotary mechanism. The second member is connected to the intermediate member by a second rotary mechanism. A second rotary mechanism includes: a second radial pin supported by a first one of the second member and the intermediate member; a plurality of pairs of rollers disposed at different positions of the second radial pin and each of the pairs of rollers holding the second radial pin therebetween; axial pins supporting the respective rollers while supported by a second one of the second member and the intermediate member; and stroke bearings respectively interposed between the rollers and the axial pins and supporting the rollers so that the rollers are rotatable around the axial pins and movable in a direction of the rotation axis.
