摘要： A process for forming a high temperature single crystal canted spring is provided. In one embodiment, the process includes fabricating configurations of a rapid prototype spring to fabricate a sacrificial mold pattern to create a ceramic mold and casting a canted coiled spring to form at least one canted coil spring configuration based on the ceramic mold. The high temperature single crystal canted spring is formed from a nickel-based alloy containing rhenium using the at least one coil spring configuration.

摘要： A vehicle transmission includes a housing part, a shaft extending from the housing part, and a spring element having a plurality of spring windings wound around the shaft, a first end of the spring element being fixed to the housing part. An actuating means is attached to a second end of the spring element and is configured to twist the second end in a circumferential direction of the spring element to thereby cause the spring element to tighten and frictionally contact an outer circumference of the shaft. The spring element is comprised of a hollow cylindrical metal base body having a helical-shaped incision that defines the plurality of spring windings. The incision may be formed in the hollow cylindrical base body by a plasma beam process, by a laser cutting process, by a flame cutting process or by a water jet cutting process.

摘要： A spring wire with a hardness of 50 to 56 HRC is subjected to first and second shot peening processes within a warm working temperature range of 150° C. to 350° C. In the first shot peening process, a first shot of a shot size of at least 1.0 mm is used. In the second shot peening process, a second shot smaller in shot size than the first shot is used. Through these shot peening processes, compressive residual stress is imparted to the spring wire. The spring wire includes a residual stress increase part, residual stress peak part, and residual stress decrease part. In the residual stress decrease part, a part including a compressive residual stress magnitude equivalent to the magnitude of the compressive residual stress at a surface of the spring wire exists at a region at a depth exceeding the permissible pit depth.

摘要： A compressible resilient elastomeric pad includes a body defining a central axis, the body formed from a predetermined material and having each of a peripheral side surface, a first axial end and a second axial end, each of the first and second axial ends having a flat surface thereof disposed normal to such central axis. A first raised projection is centrally formed on the flat surface of the first axial end and a second raised projection is centrally formed on the flat surface of the second axial end. A first groove is formed in the flat surface of the first axial end in abutting relationship with a peripheral side surface of the first projection and a second groove is formed in the flat surface of the second axial end in abutting relationship with a peripheral side surface of the second projection.

摘要： A gas spring assembly includes an end member, a piston assembly and a flexible sleeve secured therebetween. An end closure secures an end of the flexible sleeve to the piston assembly. A connector fitting connects the end closure to a support post of the piston assembly. The connector fitting includes a fitting passage and a first annular groove. A jounce bumper assembly is supported on the connector fitting. The jounce bumper assembly includes a bumper body and a bumper mount. The bumper mount includes securement pin having a second annular groove. A retaining member is received within the first and second annular grooves such that the jounce bumper assembly can freely rotate relative to the connector fitting while substantially restricting axial displacement of the jounce bumper assembly relative to the piston assembly during such rotation.
