Device for detecting the position of a shaft in a coupling element, and in particular a universal joint yoke

摘要

A device for detecting the position of a coupling element having a split hub 3 provided with ears 6 constituting a clamping means clamping the hub to the shaft 13 or other torque transmitting element, the ears 6 having throughway apertures 7 for receiving a tightening screw for the clamping means. The device comprises a resiliently yieldable element 8 mounted between the ears 6 and extending across the apertures 7 formed in the ears for preventing the positioning of the tightening screw in the absence of the shaft 13. The element 8 is retractable by the insertion of the shaft 13 in the hub 3 of the coupling element.
