A method of manufacturing an elongate shaft for delivery of a medical device may include disposing a polymeric sheath having a lumen extending therethrough over a mandrel; sliding a proximal portion of the polymeric sheath into a lumen of a metallic tubular member; placing a polymeric tubular member over the distal portion of the polymeric sheath and a distal portion of the metallic tubular member; fixedly attaching a proximal coupler to a distal end of a longitudinal support filament; inserting a proximal end of the longitudinal support filament between the polymeric sheath and the polymeric tubular member to position the longitudinal support filament alongside the distal portion of the metallic tubular member and a distal portion of the polymeric sheath; and reflowing the polymeric tubular member to secure the longitudinal support filament relative to the polymeric sheath and the metallic tubular member.

A cargo container loading and unloading system for a transportation system, the cargo container loading and unloading system including a loading zone; and at least one opening connecting the loading zone to a transportation tube of the transportation system.

A method for producing a constructed camshaft of an internal combustion engine may be used in connection with a camshaft having a cam, a shaft, and an anti-friction bearing. The method may involve machining the cam, machining the shaft to produce a setting region for arranging the cam, heating the cam and the anti-friction bearing, pushing the cam onto the shaft into a preliminary position and pushing the anti-friction bearing onto the shaft into a bearing position, equalizing a temperature between the shaft, the cam, and the anti-friction bearing by cooling at least the cam, and setting the cam onto an end position by way of pushing the cam onto the setting region.

A joining method for a medical device, in particular a surgical instrument or implant, with a shaft and an attachment to be secured on the shaft, the method having the following steps: heating the attachment or cooling the shaft, such that an internal diameter of an opening of the heated attachment is greater than an external diameter of the shaft, then placing the shaft into the opening of the attachment, and then cooling the attachment, so as to shrink the attachment onto the shaft in a manner substantially free of gaps, or heating the shaft, such that the shaft and the opening are connected by an interference fit. A corresponding medical device is produced by the joining method.

A compression collar is used for reinforcing an interference fit between a piping end and a fitting. The compression collar comprises a reinforcing ring having a tubular geometry with a radially-inward facing surface and a radially-outward facing surface. A sleeve is received around, at least in part, a portion of the radially-outward facing surface of the reinforcing ring and this sleeve wraps around one axial end of the reinforcing ring to form a stop edge thereon.

A device for positioning a shaft relative to a functional element including at least one hub for the shaft. The device may include a tailstock for axially aligning the shaft with respect to the at least one hub of the functional element. The tailstock may include a radially adjustable centring cone for the shaft. The tailstock may have an outer diameter that is smaller than an inner diameter of the at least one hub.

A component installation system includes an engagement clamp having a circular shape coupled to a robotic arm, being configured to engage an annular component. The component installation system further includes an actuator coupled to the engagement clamp and operable to cause the engagement clamp to engage and disengage the annular component, and a heating element coupled to the engagement clamp and arranged to heat the annular component engaged within the engagement clamp. The component installation system further includes a controller in communication with the robotic arm, the actuator and the heating element.

A method for manufacturing a hollow camshaft is provided, and more particularly, a method for manufacturing a combined hollow camshaft by an axial-compression upsetting-deformation technique. The present method solves a problem that the current camshaft manufactured in an internal high-pressure expansion manner in the prior art has the insufficient locking force to cause the loosening of a cam. The method is as follows: a camshaft is formed by combining two independent units, namely a cam and a shaft tube. Non-circular countersinks are distributed on two sides of the cam. Thrust steps are formed on the shaft tube correspondingly. The cam is placed between the two thrust steps of the shaft tube. The locking force is applied to the cam by utilizing the thrust steps on the two sides of the cam based on thermal expansion and contraction. Simultaneously, the thrust steps lock the cam with the countersinks.

The present invention relates to a hydraulic extrusion tool for extruding a rotor shaft for a turbomachine, and a corresponding method. The turbomachine has a structure that is fastened to the rotor shaft by a press fit. The extrusion tool has a first tool part that is configured for the purpose of being arranged on a first side of the structure, and which has a coupling mechanism that is configured for the purpose of coupling the first tool part to the structure, in such a way that the first tool part and the structure cannot move away from each other, at least in one direction along an axis of the rotor shaft; and an induction device that is configured for the purpose of heating the structure by induction in the region of the press fit.
