AI Technical Summary

Technical Problem

Existing methods for attaching components to CT scanner gantries fail to effectively decouple mechanical stresses caused by the deformation of the rotating drum/disc, leading to incomplete stress relief and potential component instability.

Method used

A device featuring a fastener with a spring assembly compressed between the fastener head and the component, utilizing a conical through-hole and positive locking section to create a preload, ensuring secure attachment and stress relief.

Benefits of technology

The device provides a stable and cost-effective connection that withstands high rotational forces, maintaining reliability under extreme conditions by securely holding components to the gantry while compensating for mechanical stresses.

Abstract

The invention relates to a device for mechanically connecting a component (30) to a gantry (2), comprising: - a fastening element (31) which is guided through a through-hole (35) in the component (30), wherein the fastening element (31) is screwed to the gantry (2), - a spring assembly (37) mounted on the fastening means (31), wherein the spring assembly (37) comprises one or more springs, wherein the at least one spring is arranged between a head (33) of the fastening means (31) and the component (30), wherein the at least one spring is compressed to generate a preload that securely holds the component (30) to the gantry (2), wherein the component (30) has a fastening section (32) in which the through-hole (35) is arranged, wherein the through-hole (35) has a conical expansion (39) on the side facing the gantry (2), wherein the fastening means (31) has a positive locking section (34), wherein the positive locking section (34) is positively locked in the conical expansion (39).
