A crowning is formed at an end of a loaded rolling element rolling surface of a movable member, and a chamfer is formed at an end of the crowning. Let a total length of the crowning and the chamfer in a length direction of the loaded rolling element rolling surface be L. Let the diameter of a ball be Da. L/Da>4 is set. A maximum depth D of the chamfer is set to equal to or greater than the elastic deformation amount of a rolling element rolling surface of a track member, the loaded rolling element rolling surface of the movable member, and the rolling element under a radial load equal to or greater than 60% of the basic dynamic load rating.

摘要： In an actuator, an unnecessarily large load is prevented from being applied to a shaft and a workpiece. There are included a force sensor, an output of which is according to a force applied to a connecting member connected to the shaft, an amplifier that amplifies the output of the force sensor, and a low-pass filter, and a load applied to the shaft is detected based on an output from the amplifier until the shaft or a member associated with the shaft comes in contact with another member, and thereafter, the load applied to the shaft is detected based on an output from the low-pass filter.

摘要： A guide device includes a track member and a moving member engaged with the track member with a plurality of rolling elements interposed therebetween. A lubricating path is formed in the moving member for supplying lubricant to a circulation path for the rolling elements. The lubricating path has a common path including an inlet portion that serves as a supply port for the lubricant, a first path through which grease flows, and a second path through which lubricating oil flows. A cross-sectional area of the second path is smaller than a cross-sectional area of the first path, and in the common path, a second communication portion of the second path is located closer to the inlet portion than a first communication portion of the first path. Further, the guide device includes a plug member for blocking the inlet portion of the common path, the plug member being removable and able to be moved within the common path.

摘要： A guide apparatus includes a track member, a movable member having a first rolling surface that forms a load rolling passage together with a rolling surface of the track member, and a damper provided on a first surface. The first surface is at least a portion of the surface of the movable member opposed to the track member excluding the first rolling surface. The damper includes a plate member disposed in such a way as to cover the first area and a reservoir space formed between one surface of the plate member and the first area. The reservoir space contains a damping medium and allows the plate member to displace relative to the first area. The damper is provided on the movable member in such a way that the other surface of the plate member slides on at least a portion of the surface of the track member opposed to the movable member.

摘要： An object of the present invention is to provide a technique for a gripping system having an arm mechanism and a hand mechanism attached to the arm mechanism, by which an operation of the arm mechanism can be stopped as soon as the hand mechanism contacts an object. In the gripping system according to the present invention, the hand mechanism is provided with a contact detection unit for detecting that a predetermined site of the hand mechanism has come into contact with the object. The hand mechanism is also provided with a signal transmission unit that is electrically connected to an arm control device. The signal transmission unit transmits a command signal to stop the operation of the arm mechanism directly to the arm control device at the point where the contact detection unit detects that the predetermined site of the hand mechanism has come into contact with the object.

摘要： A screw device is provided which can detect damage to a groove of a screw shaft, the damage being hidden by a nut, with a high probability. At least two circulation components are mounted on a nut in such a manner as to form at least two circulation circuits that circulate rolling elements. The nut is provided with a sensor that detects a displacement of a groove of a screw shaft between the adjacent circulation circuits.

摘要： Provided is a ball screw device which enables easy production and assembly of a nut member and formation of an endless circulation path for balls in the nut member with high accuracy. The nut member includes a plurality of nut components arranged in a superposed manner along an axial direction of a screw shaft. At a boundary portion between the nut components which are adjacent to each other, a raceway path for balls extending around a periphery of the screw shaft is formed. A joining surface of each of the nut components used for joining with another one of the nut components includes: a raceway forming surface which is annularly formed around the through hole; and an abutment surface for joining which is formed on an outer side in a radial direction with respect to the raceway forming surface.

摘要： This hollow shaft member 10 includes paired diameter-reduced sections 11 respectively formed at both shaft ends of a hollow shaft-like tubular material by performing swaging processing on both the shaft ends, and an intermediate section 12 located between the paired diameter-reduced sections, and having an outer diameter larger than an outer diameter of the paired diameter-reduced sections. Shapes of connection boundaries between the intermediate section 12 and the diameter-reduced sections 11 are formed as perpendicular step-shaped sections 13 stepped substantially perpendicular to an axial direction, and the perpendicular step-shaped sections 13 are formed by the swaging processing. With such a configuration, a hollow shaft member for a rolling device in which a weight reduction has been achieved can be provided.
