Hello everyone.
I'm calling on your technical knowledge because I'm drying up a bit even if I have a little idea.
Can someone tell me which mechanical component is represented in the center of the image? Planetary gearbox, clutch...
Thank you for your answers.
Hello @OlivierH
It's not a gear it seems to me, the teeth of a pinion are not represented like that in industrial drawing.
But as below

This system allows the central piece 1 to rotate (one rotation) and the ball 2, allows the elements on the outside 3 to move laterally, or to have freedom laterally.

Much like a gearbox dog, can turn and move sideways to mate to a one-speed sprocket.
Part 3 is connected to 6 by a screw and serves as a stop surely, parts 4 & 5 are connected by screw 7 and can move it seems to me.

In addition, we can imagine that on the central part the bore 1 serves as a clearance for the washer and the screw 2 when the assembly moves, or its disassembly?
3 is a key that allows rotation drive

Do you have the drawing as a whole?
Hello,
I will see this set in yellow more as a silent block (peripheral circular part would be made of rubber). But indeed @FRED78 if we could have the entire plan with the nomenclature it would facilitate interpretation

Thank you for your answers. Here is the complete plan but I don't have the nomenclature. It is a clamp.
