Embodiment Construction

[0111] FIG. 1 shows in particular an embodiment of a bimetallic composite system formed from a first part 1 and a second part 2 , wherein the second part extends at least partially through the first part along an imaginary longitudinal axis L of the composite system. As can be seen from FIG. 1, the second part 2 here has an at least partially curved outer surface, in particular configured as a cylinder, which touches the inner surface of the first part 1 flush so that the first part has at least Sectionally at least partially enclosing the second component, creating a composite system of first and second active surfaces 1B, 2B. In order to increase the fatigue strength of the composite system, in particular to increase the pull-out strength of its second part 2 from the first part 1, the composite system effective surfaces 1B, 2B formed by the surfaces of the two parts, in particular in direct contact, are formed in such a way that The two parts 1 , 2 have partial contours TK ...

Abstract

To improve reliability with respect to fixing of a compression element and its drive motor into a casing, in a hermetic compressor. Since a shape of a welding hole 20 is conical, weld surely reaches a projection part 17 and prevents defects such as stay of the weld on a surface of a case.

Description

technical field [0001] The invention relates to a composite system, in particular formed as part of a vibrating measuring transducer with at least one measuring tube vibrating in operation, comprising a first part, in particular made of metal, and a connection therewith In particular the second part also made of metal. Furthermore, the invention relates to a method for producing such a composite system, which is especially suitable for vibration-type measuring transducers. Background technique [0002] In industrial measurement and automation technology, in-line measuring devices with vibration-type measuring transducers are used for high-precision recording of process variables, especially fluid dynamics and / or rheological measured variables, especially of media flowing in pipelines. Such measuring instruments usually comprise at least one measuring tube which communicates with the pipeline of the transfer medium and vibrates during operation. Examples of structure, funct...
