A method of mounting an elastic ring, e.g. sealing ring, on a body via a mounting unit is presented, having at least three fingers which are movable relative to each other. The method comprises holding and clamping the ring on the exterior side of the fingers which extend into a cross-section framed by the ring, moving at least one finger along a circle or a plurality of fingers along a common circle or a plurality of concentric circles such that the elastic ring is stretched and the cross-section thereof is increased, moving the ring and the component relative to each other so that the component projects into the cross-section and the ring extends around the component, moving one or more fingers relative to each other so that the ring contacts the component in sections between adjacent fingers, and moving the fingers out of the ring. Also disclosed are a mounting unit for executing the method, and a ring mounting device including such a mounting unit.

An outer ring (29) is first transported to an insertion point (E) in the feed device (34). At the same time, a circular blank ring (30) is brought into a starting position (P) in the feed device. The circular blank ring (29) is first aligned coaxially with respect to an axis (A) using a centering body (61). The circular blank ring moves solely radially with respect to the axis (A). The circular blank ring (30) is then inserted into the hole of the outer ring (29). During this movement, the circular blank ring is aligned coaxially with respect to the axis (A) preferably using a centering channel (54). The circular blank ring (30) carries out a superimposed movement in the axial direction (V) and in the radial direction radially with respect to the axis (A).

An object of the present invention is to provide a device for installing a retaining ring on a shaft which can reduce the labor intensity of workers. The device for installing a retaining ring on a shaft comprises an expansion assembly. The expansion assembly includes a shell. A push block is movably fixed in the shell. Two expansion members that are symmetrical left and right are arranged in front of the push block. The expansion members include expansion portions that are located outside the shell and extend outward. Rear ends of the expansion portions are expansion portion first sections. The expansion members comprise a left expansion member on the left side and a right expansion member on the right side. The left end face of the expansion portion first section of the left expansion member is a slope extending leftward from rear to front. The push plate moves in a front-rear direction so that the expansion portions of the two expansion members move left and right, respectively. A loading rod is fixed on the lower side of the shell. A front edge of a front portion of the loading rod extends outward in a circumferential direction to form a limiting bump. A compression spring is sheathed on a rear portion of the loading rod. A front end face of the loading rod is recessed inward to form an evading groove.

A manifold having a first sub-manifold defining a first fluid passage, a second sub-manifold defining a second fluid passage, and a seal-sub occupying an interface between the first and second fluid passage and that seals against the first and second fluid passages to prevent fluid leaks at the interface. The first sub-manifold defines an opening for receiving the seal-sub into the first fluid passage from outside the first sub-manifold that is separate from the interface.

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.

A device for press-fitting an oil seal S that includes a fixing section F in which a hard ring S is embedded and a lip section L into a structure A. The device includes an air hammer AH that includes a hammer head 1. The hammer head 1 includes a pressing section 6 configured to abut the fixing section F and a holding section 7 configured to abut the lip section L, and a negative pressure space 8 is formed between the hammer head AH and the oil seal S between the pressing section 6 and the holding section 7. The hammer head 1 is provided with an air suction path 11 that is open to the negative pressure space 8 at one end and is connected to an air suctioning means 10 at the other end. Accordingly, the device holds by suction the oil seal S having a complicated shape without deforming it, and adequately press-fits it into a structure A.

Providing a seal member taking-out device which can successfully take out a larger number of seal members. The seal member taking-out device includes a shaft member, a cylinder member, a moving member, and a taking-out member. The shaft member is columnar or cylindrical. The cylinder member is cylindrical and the shaft member is inserted through the cylinder member so that the cylinder member is movable in a direction of a central axis of the shaft member. The cylinder member is shorter than the shaft member and extends in the direction of the central axis of the shaft member. The moving member moves a plurality of seal members stacked on the shaft member and the cylinder member, in a direction of a distal end of the shaft member. The taking-out member takes out the seal members from the distal end of the shaft member.

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.

An apparatus for use in installing and verifying installation of a seal member in a component, and including a housing defining an interior sized to receive the component therein, and a moveable lid selectively positionable between a loading position and a sensing position. The apparatus also includes at least one seal sensor coupled to the moveable lid and configured to selectively align with a first sensing point on the component when the moveable lid is in the sensing position. The at least one seal sensor is configured to only actuate when pressed against the seal member positioned at the first sensing point.

In a state where a pair of protrusion portions of a ring portion is clamped by front end engagement portions of a pair of claw members (71) (72), the front end engagement portions of the pair of claw members are swung in a direction approaching each other about a pivotal supporting portion (80). A sliding body (77) slides with the contact of the front end engagement portion to the ring portion or to the protrusion portion thereof so as to follow a radial and circumferential displacement of the protrusion portion accompanying a diameter reduction of the ring portion.
