Wellenanordnung variabler Länge

摘要

A first shaft has a tubular polygonal end, and a second shaft has a correspondingly polygonal solid end telescopically disposed in the polygonal tubular end. An arched spring in a spring chamber in the solid polygonal end has a planar body portion bearing in sliding engagement on a planar wall of the polygonal tubular end and biasing the polygonal solid and tubular ends in opposite directions to a substantially zero clearance relationship in which linear clearances are reduced to substantially zero. A monolithic plastics block is injection moulded in situ in the spring chamber behind the flat body portion. After the in situ injection moulded plastics solidifies, the monolith plastics block captures the substantially zero clearance relationship between the polygonal solid and tubular ends. It encases the arched spring such that the flat body portion defines a reinforced wear plate on the block in sliding engagement on the planar wall of the tubular polygonal end.
