A compliant spacer which, in use, is located between planar surfaces of two machine elements which are, in use, clamped together in an assembly, the spacer having a first generally planar face and a second oppositely facing generally planar face which is generally parallel to the first generally planar face, each of the first and second generally planar faces having a plurality of raised regions, the raised regions of the first face being offset with respect to the raised regions of the second face, so that as the two machine elements are clamped together with the spacer therebetween, the spacer deforms out of plane to maintain the clamping load in use, and each raised region including a bearing surface and edge regions where the raised region joins the respective planar face of the spacer, the bearing surface being generally planar and parallel to the first and second planar faces, and the edge regions of the raised regions melding smoothly into the respective planar face of the spacer without any sharp discontinuity.
Entretoise souple qui, à l'utilisation, est placée entre les surfaces planes de deux éléments de machine qui sont, à l'utilisation, serrés ensemble en un assemblage. L'entretoise comprend une première face généralement plane et une seconde face généralement plane, opposée et généralement parallèle à la première face. Chacune des deux faces généralement planes possède plusieurs zones surélevées, celles de la première face étant décalées par rapport à celles de la seconde face. Ainsi, les deux éléments de machine sont serrés ensemble avec l'entretoise entre eux, et la surface de l'entretoise se déforme et perd sa planéité pour maintenir la charge de serrage. Chaque zone surélevée, qui comprend une surface portante et des surfaces latérales, rejoint la face plane respective de l'entretoise; la surface portante est alors généralement plane et parallèle aux deux faces, et les surfaces latérales des zones surélevées s'intègrent en souplesse à la face plane respective de l'entretoise, sans discontinuité nette.
