Method for assembling a beam and a structural element of an airplane seat
The present invention essentially relates to a method for assembling a beam and a structural element of an aircraft seat, characterised in that it comprises: a step of producing at least one recess in an inner face of a beam passage area of the structural element, a step of inserting the beam into the beam passage area, and a step of deforming the beam such that a deformed portion of the beam penetrates into the recess of the beam passage area.
Chain guide
To provide a chain guide that can improve transportability and assembly operation efficiency, while also ensuring stable running of a timing chain and enhancing durability, with a simple structure. The chain guide has a guide shoe that slidably guides a chain, and a chain guide body that supports the guide shoe. A compression limiter having an attachment hole through which a mounting bolt for attaching the chain guide to an attachment target member passes is fitted in a fixing through hole extending through the chain guide body in a width direction thereof. A compression limiter holding mechanism is provided either to the compression limiter or to a hole rim part including the fixing through hole of the chain guide body in order to hold the compression limiter.
Stop washer for an elastomeric bearing, elastomeric bearing and subframe for a vehicle
A stop washer for an elastomeric bearing is manufactured as a single unit from a sheet metal blank and furnished with a surface protection. In addition to its function as a path limiter, it has at least one of the following functions by a structure integrated into the forming process of the sheet metal blank, namely the function of a thread and/or anti-rotation protection. Furthermore, an elastomeric bearing with such a stop washer and a subframe equipped therewith are conceivable.
Heavy-duty connections e.g. for axle/suspension systems
A vehicle component such as an axle spindle or suspension beam (3) is connected to a tubular vehicle axle (1) by fitting a connector sleeve (2) onto the axle and subjecting the assembly to a crimping operation in which plural depressions (206,2018) are formed by indentation in the connector sleeve and the axle wall at the connection region (11,12) to fix the connector sleeve on the tubular axle. In the described proposals a solid lubricant (4) such as molybdenum disulphide is applied at the connection region between the connector sleeve (2) and axle (1), before crimping. The further vehicle component (3) is then connected to the connector sleeve (2) by welding.
METHOD OF MANUFACTURING JOINED MEMBER
A method of manufacturing a joined member where joining portions of at least two members are integrally formed with each other by press working thus joining said at least two members, the method comprises an engaging step, an inserting step, and a press working step.
METHOD FOR MACHINING OUTER CIRCUMFERENCE OF METAL END CROSS-SECTION AND METHOD FOR JOINING METAL COMPONENT OBTAINED BY THE MACHINING METHOD WITH ANOTHER MEMBER
Provided are a method of for machining the outer circumference of a metal end cross-section, the method being capable of easily forming at least any of a deep groove, a deep recess, and a flange which are smooth and uniform in the longitudinal direction of a metal rod or metal pipe in the periphery of the cross-section of any of the end part of the metal rod or metal pipe, the drawn end part of the metal rod or metal pipe, and the hub hole forming part of the metal pipe; and a method for joining a metal component obtained by the machining method with another member. The machining method of the present invention is characterized in that: splitting is advanced by successively repeating press forming operation multiple times by using a slitting punch, in which a tip part has a sharp cutting edge, and the cutting edge is formed so as to have a shape equal to or partly equal to the outer shape of the cross section of a metal end part and so as to have a diameter smaller than the outer diameter of the cross section of the splitting object; and in order to control the depth of metal cracking cleft created with each press forming operation, a pressing die for pinching the outside of a metal rod or at least a pressing die of one side of pressing dies for pinching the inside and the outside of a metal pipe is disposed while its position is moved according to the distance of a split portion.
COLD-WORKED RIVETED PISTON/ROD ASSEMBLY AND METHOD OF MAKING SAME
A piston and piston rod assembly includes a piston rod having a first portion and a smaller second portion extending from the first portion. The second portion has a circumferential groove that receives at least one sealing ring or O-ring located between the first portion and the free end of the second portion. A piston has an aperture extending between two ends, with the top open end having a larger diameter than the bottom open end. The second portion of the piston rod is inserted through the aperture of the piston so that the free end of the second portion emerges through the top open end of the piston and compresses the at least one sealing ring or O-ring with the inner surface of the piston. The free end of the second portion of the piston rod is cold-worked to overlie at least a portion of the top open end of the piston.
Connecting member of structure
A bracket includes a cylindrical portion and a plate-shaped portion that are integrally formed. The cylindrical portion is provided at one end side of a blank along one direction and is provided with a slit extending over an entire length of the cylindrical portion in the one direction as a result of forming a portion at the one end side of the blank along the one direction into a cylindrical shape extending in the one direction. The plate-shaped portion is provided at the other end side of the blank along the one direction. The cylindrical portion of the bracket is inserted in the cylindrical body member formed of an aluminum alloy material, and the body member and the cylindrical portion are clinched by electromagnetic tube compression.
Steer axle assembly
A steering stop mechanism including a fastener, a retention element disposed about the fastener, an adapter configured to receive at least a portion of the fastener therein, and a retention sleeve disposed about at least a portion of the fastener, the retention element, and the adapter. The retention sleeve is deformable and produced from a malleable material to allow the retention sleeve to conform to a shape of the retention element and the adapter during assembly of the steering stop mechanism with a working component.
CONNECTION ARRANGEMENT FOR AXIALLY SECURING A SHAFT-HUB CONNECTION, AND METHOD FOR AXIALLY SECURING A SHAFT-HUB CONNECTION
A connection arrangement for axially securing a shaft-hub connection includes a shaft and a hub with an inner stop surface for the shaft and an outer groove for axially positioning a securing device. The securing device has an axially extending sleeve-shaped part and a radial collar. The sleeve-shaped part at least partly surrounds the circumference of the hub, and the radial collar at least partly engages behind the annular end surface of the hub. The inner stop surface for the shaft in the housing is formed by a recess. The securing device includes a radially deformable holding socket, the axially extending sleeve-shaped part of which is surrounded by a tensioning strap. The holding socket region which is offset radially inwards surrounds the expanded outer groove of the hub coaxially in the assembled state of the shaft-hub connection and can be locked in the expanded outer groove of the hub by the tensioning strap, the radial collar of the holding socket resting against the axial securing ring of the shaft in the locked state.
