  • Publication number: 20180339379
    Abstract: A method of manufacturing a component and a component manufacturing apparatus attach an attached part in a predetermined posture decided in advance to a ring-shaped channel formed in an outer circumference of a component main body. While being held by holding portions, a ring-shaped seal body is placed in contact with a tapered portion and has its diameter expanded to at least the outer diameter of the component main body. The seal body elastically deforms from the expanded-diameter state so that its diameter reduces and is attached to the attachment channel in the outer circumferential surface of the component main body while being guided by the holding portions.

  • Publication number: 20180312379
    Abstract: A vertical moving method of a vertical moving unit on which a conveyance target object is mounted includes steps of causing a non-electric biasing unit to generate a biasing force to raise the vertical moving unit, causing an electric motor unit to generate a thrust in a direction to raise the vertical moving unit or a thrust in a direction to lower the vertical moving unit, and causing an electromagnetic brake unit to generate a braking force to resist a movement of the vertical moving unit. Independently of presence/absence of the object and a weight of the object, the thrust and/or the braking force is controlled such that the vertical moving unit stops when an external force of overload more than a predetermined value acts on the vertical moving unit during a vertical movement.

  • Publication number: 20180281131
    Abstract: A method of manufacturing produces an assembled product where a ring-shaped seal is attached to a channel in an inner circumferential surface of a ring-shaped component. The method includes: a holding step that moves an engaged portion of the seal inwardly in a radial direction using a deformation member, while restricting movement of the seal in a direction parallel to an inner circumferential wall of the channel, to cause deformation so that the outer diameter of part of the seal aside from the engaged portion becomes smaller than the channel inner circumferential diameter; and an attachment step that attaches the seal to the channel by releasing the seal to restore the seal from the deformation. The attachment step includes releasing the seal by releasing engagement by the deformation member and moving the seal body inside the channel while pressing out the seal body from inside.
