Claim 17:
18. Spring-based suspension means for use in a device according to claim 1, wherein said spring-based suspension means comprises at least one leaf spring, preferably at least three leaf springs, more preferably three leaf springs;
wherein said spring-based suspension means comprises an outer contour and an essentially circular inner contour suitable for receiving an outer part of a first bearing; said spring-based suspension means preferably being essentially ring-shaped;
wherein said spring-based suspension means is adapted for flexibly exerting an axial force on a rotationally moveable axis of said device while radially fixating said axis, whereby said flexibly exerting of said axial force is performed by said at least one leaf spring on said outer part of said first bearing when said first bearing is mounted between said spring-based suspension means and said axis, and whereby said radially fixating of said axis is performed at least partly by radially fixating said outer part of said first bearing when said outer part is received by said inner contour and said first bearing is mounted between said spring-based suspension means and said axis
wherein said at least one leaf spring preferably extends along a tangential direction with respect to said outer contour, and wherein at least 50% of said outer contour belongs to any of said at least one leaf spring;
wherein preferably said suspension means comprises an essentially conical surface, more preferably at least three conical surface protrusions, most preferably three conical surface protrusions, provided near said inner contour for facilitating said receiving of said outer part for radial fixation of said outer part;
wherein preferably said spring-based suspension means is configured to exert said axial force only on an outer rim of said outer part of the first bearing; wherein preferably said outer part comprises a bearing rotation axis and an outer diameter (D); wherein preferably said outer rim corresponds to portions of the outer part distanced for at least an outer rim diameter (E) from said bearing rotation axis, said outer rim diameter (E) preferably being not smaller than 85% of said outer diameter (D), more preferably not smaller than 90% of said outer diameter (D); most preferably not smaller than 95% of said outer diameter (D).
