Vorrichtung zum Zusammensetzen eines mechanischen Elementes in einer Rotationsbewegung mit einem zweiten koaxialen äusseren Element durch Reibung.

摘要

Device for making two coaxial rotating mechanical elements (1, 2) integral by friction between two friction zones (3, 4) generated by traction on the inside element exerted by the threaded end with pitch n of shaft (10), screwing into a threaded hole (12) of inside element (1). Shaft (10) is also laterally threaded with pitch (10') equal to that of threaded pins (7) supported by housing (9) coaxial with the shaft. When end (11) of shaft (10) is screwed into hole (12), pins (7) rotate tangentially along the inside threading of pitch m of bushing (5) wedged in outside element (2) and translate with housing (9). When friction surfaces (3, 4) of the two elements come in contact, a further rotation of shaft (10), pitches m and n being different, causes the relative locking. Coupling between shaft (10) and pins (7) and the coupling between the pins and bushing (5) are of the forced type, obtained by an interference between the various threads.
