摘要： A slider for linear guide devices, which slider moves along track rails provided on a stationary section such as a bed and a column to guide a moving body such as a work table of a machine tool and industrial robots while bearing a load. Such slider is manufactured by overlaying a synthetic resin on a metallic block body provided with load rolling surfaces for balls, by injection molding such that side surface molding sections for formation of ball return holes are overlaid on the outer side surfaces of the block body, end surface molding sections for formation of ball direction changing portions are overlaid on front and rear end surfaces of the block body, and a top surface molding section is overlaid on the top surface of the block body simultaneously with formation of the side surface molding sections and end surface molding sections so that such top surface molding section connects the end surface molding sections positioned on the both end surfaces of the block body to each other.

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.

摘要： A mobile robot includes: a drive unit that changes a moving speed and a travel direction; a detection unit that detects a plurality of detection target objects 11; and a control unit 27 that acquires a distance Z and a direction θ to the detection target object unit, calculates a travel direction in which the distance and the direction to the detection target object satisfy a predetermined relationship, and drives and controls the drive unit on the basis of the calculated travel direction. The control unit calculates a distance x in a direction orthogonal to the movement route between the detection target object and a current position of the mobile robot and the direction to the detection target object, calculates a difference δx between the distance x and a certain distance Xref, and executes drive control for the drive unit to cause the difference δx to be 0 (zero).

摘要： A suspension is provided which can not only generate a damping force between sprung mass and unsprung mass but also steer a wheel. A suspension includes: a shaft coupled to sprung mass of a vehicle, the shaft having a screw groove and a spline groove formed thereon; a ball screw nut assembled to the shaft via a ball; a ball spline nut assembled to the shaft via a ball; a ball screw-specific motor connected to the ball screw nut; a ball spline-specific motor connected to the ball spline nut; and a case coupled to unsprung mass of the vehicle, the case being configured to hold the ball screw-specific motor and the ball spline-specific motor. The ball spline-specific motor rotates the ball spline nut and the shaft relative to the case.

摘要： A motion guide apparatus is provided which can make a carriage compact without reducing a rated load and an allowable load. The motion guide apparatus includes: a track member (1) and a carriage (2) that moves along the track member (1). A circulation path (7) of the carriage (2) includes a loaded path (C1), a return path (C2) parallel to the loaded path (C1), and a substantially U-shaped turn path (C3) connected to the loaded path (C1) and the return path (C2). At least a part of the turn path (C3) bends in side view in a direction where the loaded path (C1) and the return path (C2) coincide.
