Micromechanical component with opening for attachment on a spindle

摘要

The micromechanical part has an opening (10) whose edges include an alternating arrangement of rigid areas (11) and elastic areas (12). Ends (13) of the rigid areas that are closest to a center (C) of the opening are connected by a circle (C1) that has a diameter greater than a diameter of another circle (C2). The circle (C2) connects ends of the elastic areas that are closest to the center of the opening. Each rigid area is formed by a convex portion that projects into the opening. Each elastic area is formed by a curved arm. Independent claims are also included for the following: (1) a method of transmitting a torque (2) a method for reducing risks of obtaining a defective assembly during production of an assembly formed by a micromechanical part and a spindle (3) a method for forming an assembly formed by a micro- mechanical part and a spindle.
