A method comprises securing a first component of a lockable adjustment assembly to an end A of a first rigid tube via a first releasable coupling assembly. The method also comprises securing a second component of the lockable adjustment assembly to an end C of a second rigid tube via a second releasable coupling assembly. Further, the method comprises moving the first component and the second component, loosely coupled with each other, relative to each other with only three degrees of freedom to position the first rigid tube and the second rigid tube in a selected orientation with respect to each other. The method also comprises, with the first rigid tube and the second rigid tube in the selected orientation relative to each other, locking the lockable adjustment assembly so that the first component and the second component have zero degrees of freedom relative to each other.

A method for producing a joining connection between a joint housing and at least one connection component including: providing a blank for the fabrication of the joint housing, and providing a connection component with a joint receptacle inserting the blank into the joint receptacle of the connection component and producing the joint housing through forming by cold extrusion of the inserted blank. An undercut positive-engagement joining connection is generated between the joint housing and the connection component during the cold extrusion process through transverse extrusion and/or upsetting. A chassis component has a structural component part with at least one joint receptacle formed as orifice and a joint housing for a joint device, which joint housing is inserted into this joint receptacle and fastened to the structural component part.

A method of manufacturing an outer joint member of a constant velocity universal includes forming cup and shaft members of medium carbon steel, preparing, as the cup member, a cup member having cylindrical and bottom portions integrally formed by forging, and a joining end surface formed on an outer surface of the bottom portion after the forging, preparing, as the shaft member, a shaft member having a joining end surface to be joined to the bottom portion of the cup member, and bringing the joining end surfaces of the cup and shaft members into abutment against each other. The method also includes welding the cup and shaft members from an outer side of the cup member to an abutment portion between the cup and shaft members in a radial direction of the cup member.

A hydraulic tension adaptor comprising a flange housing, a bolt support retainer, a bolt tensioning piston, a plurality of stud assemblies, and a retainer ring. The bolt tensioning piston houses a portion of the bolt support retainer. The bolt support retainer threadedly engages with the flange housing. The retainer ring threadedly engages with the bolt support retainer. Ports located on the bolt tensioning piston allow pressure to be exerted on the system via supply and bleed ports, thus applying tension to the plurality of stud assemblies simultaneously.

Sucker rods include end fittings having an outer wedge portion proximate to an open end, an inner wedge portion proximate to a closed end, and an intermediate wedge portion between the outer and inner wedges. Each wedge includes a leading edge, a trailing edge, and an angle between the leading and trailing edges. The triangular configuration, length of the leading edge, the length of the trailing edge, and size of the angle in each wedge portion cause distribution of force, such that compressive forces distributed to the rod proximate the closed end exceed compressive forces distributed to the rod proximate the open end. An automated installation procedure installs the end fitting through the use of multiple chucks, positioned by servo motors along a fitting table.

The ball socket assembly includes a housing with an open interior which extends along an axis. A bearing is disposed in the open interior of the housing and has a curved primary contact surface which surrounds the axis and surrounds a stud ball opening. A stud ball is disposed in the opening and is in sliding contact with the primary contact surface for allowing rotation of the stud ball relative to the bearing. The stud ball has an equator and is in sliding contact with the bearing on both sides of the equator. A stud is operably connected with the stud ball. A shoe is further provided and has a pair of supplemental contact surfaces that are biased against the stud ball. The shoe provides the stud with a predetermined rotational torque and also adjusts for wear in the assembly to maintain the performance of the socket assembly.

A modeling assembly (100) for layout of rigid tubing comprises a first releasable coupling assembly (110) and a second releasable coupling assembly (120). The modeling assembly (100) also comprises a lockable adjustment assembly (130) comprising a first component (140) and a second component (150). The first component (140) is configured to be removably coupled to an end A of a first rigid tube (102) via the first releasable coupling assembly (110). The second component (150) is configured to be removably coupled to an end C of a second rigid tube (104) via the second releasable coupling assembly (120). With the lockable adjustment assembly (130) in the loose coupled state, the first component (140) and the second component (150) have only three degrees of freedom relative to each other. With the lockable adjustment assembly (130) in the locked coupled state, the first component (140) and the second component (150) have zero degrees of freedom relative to each other.

A universal joint includes a bearing including a bearing cup fitted in a bearing hole of a yoke and rolling elements arranged between the bearing cup and a shaft portion of a cross shaft. A method for manufacturing the universal joint includes: simulating a shrunken state in which a sample bearing cup selected from bearing cups in a same lot is fitted in the bearing hole such that only an outside diameter is restrained, by press-fitting the sample bearing cup into a reference hole of a reference jig; measuring a diameter of an inscribed circle inscribed to the rolling elements in the shrunken state; setting an outside diameter of the shaft portion to a required outside diameter according to the diameter of the inscribed circle; and inserting the bearing cup with the rolling elements between the shaft portion having the required outside diameter and the bearing hole.

A manufacturing method is used for an outer joint member of a constant velocity universal joint. The outer joint member includes a cup section having track grooves formed in its inner periphery, which are engageable with torque transmitting elements, and a shaft section formed at a bottom portion of the cup section. The manufacturing method includes welding the cup and shaft members by irradiating a beam to joining end portions of the cup and shaft members, causing an outer surface including the welded portion to be formed into a flat smooth surface by removal processing, irradiating ultrasonic waves to the flat smooth surface with one probe at an incident angle which prevents total reflection in a circumferential angle beam flaw detection method, and setting a focal point of the ultrasonic waves to positions from a surface to an inside of the welded portion, to thereby perform inspection.

A method for tightening a thread joint of a base part with a small thread pitch and a part to be attached with a large thread pitch by rotation in screw-in direction of a differential thread connector, including portions of a one-directional thread corresponding to the threads of the base part and the part to be attached. The differential thread connector can be screwed on the small thread of the base part to a predetermined length, subsequently the part to be attached is screwed on the large thread of the differential thread connector until contact with the base part is reached, and the preliminary tightening is carried out in screw-in direction, and subsequently the differential thread connector is rotated in screw-out direction and the final tightening is carried out.
