Abstract
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.
Claims11
A device for detecting the position of a coupling element having a split hub and spaced apart ears of clamping means for the hub, on a shaft or other torque transmitting element, said hub defining a throughway passage for said shaft, said ears defining throughway apertures for receiving a screw for tightening the clamping means, said device comprising a resiliently yieldable element mounted on the hub and having a strip disposed between said ears and extends into said passageway and an end portion which extends across said apertures to prevent full insertion of said screw in said apertures in the absence of said shaft, said strip of the resiliently yieldable element being positioned and arranged to be urged by said shaft laterally back out of the path of the shaft upon insertion of said shaft in the hub of the coupling element so that said end portion ceases to extend across said apertures and clears the screw when the shaft has sufficiently penetrated the hub.
