    摘要: A vertical seismic isolation device includes: a fixed frame; a movable frame arranged on the fixed frame; a support guide mechanism which allows only vertical movement of the movable frame; and a restoration member which maintains a constant distance between the movable frame and the fixed frame. The support guide mechanism includes: a track rail provided on the fixed frame; a moving block assembled to the track rail through rolling elements; a support leg, which has one end coupled to the moving block and another end coupled to the movable frame, and converts vertical movement of the movable frame into a motion of the moving block; and an auxiliary leg, which is half as long as the support leg, and has one end coupled to the support leg at an intermediate position in a longitudinal direction of the support leg and another end coupled to the fixed frame.

    摘要: A motion guide apparatus which can prevent the motion guide apparatus from rattling when being used in an environment Where an excessive moment works thereon. 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.
