Spring component and support bearing for helicopter tail rotors and support structure for use in outer space

Abstract

A spring component for support bearings of helicopter tail rotors or for support structures for use in outer space encompasses at least two contact support components (11a, 11b) for connecting with the members that are to be supported (e.g. a belt and a control sleeve of a helicopter tail rotor), as well as a web plate (20), which extends between the contact support components (11a, 11b) and which includes a pair of lengthwise webs (21a, 21b) extending in a longitudinal direction. The lengthwise webs are connected to each other by first connecting webs (22a, 22b). Respectively, a further connecting web (23a, 23b) is arranged at a section of the two lengthwise webs (21a, 21b) positioned between the first connecting webs (22a, 22b), wherein each further connecting web extends outwardly toward one of the support components (11a, 11b). In connection with a transverse bending moment acting on the spring component, a twisting of the lengthwise webs (21a, 21b) takes place. The spring component is flexible for transverse bending and comprises a high supporting force. A support bearing for a helicopter tail rotor or a support structure for use in outer space encompasses two or more of the spring components. In a control sleeve bearing of a helicopter tail rotor the belt is held in the control sleeve between two oppositely positioned spring components.
