Socket for optical lenses, mirrors, angle measuring disks and other rotating bodies

The present invention relates to an optical fit Lenses, mirrors, angle measuring discs and other rofessional bodies, their central axes relative to the fit, or to their jüefestigungsorganen very precisely a predetermined position and orientation need to take.

Up to now, attempts have been made to solve this problem in that the body to be grasped is as solid and precise as possible in one

But if you do not have a socket body with the same coefficient of thermal expansion for this purpose How the material of the contained body is used, there are fluctuations in rigid frames as a result of i'emp er a door unequal and / or impermissible stresses in the captured body and corresponding deformations. Nickel alloys with extremely high nickel contents have thermal expansion coefficients similar to glass, but are made from others, e.g. B. processing reasons bad for the production of Suitable for sockets. On the other hand, putties that remain soft are only useful for setting window panes because it is there it is not a question of maintaining the exact position of the framed glass pane, but only of sealing and secure fastening,

The fitting according to the invention also shows great advantages if the wearer of the captured The body of revolution is at times exposed to considerable vibrations or acceleration influences, because the momentary forces are absorbed by the transversely elastic mounting rings and the captured body is not destroyed or is released from the socket, but after the interference has subsided under the influence of the elastic Restoring forces is returned to the i> oll position. ± ls can be as annular and over the entire circumference of their Cross-sectional area resilient holding and centering elements, Voil rubber rings, metal tube rings, with one under overpressure standing fluid-filled rubber loop, preferably but helical spring washers with transverse to the support surfaces on the mounted itotation body and on the rigid fitting parts oriented peder wire induction planes are used.
