2. Translational (or static) links through obstacles

2.1 Wedge or transverse key assemblies

The two parts to be assembled are engaged one inside the other (conical or cylindrical assembly). The key passing through the two parts rests on one and pushes on the other in the opposite direction to disassembly. It is subjected to shear stress when the assembly transmits an axial force or torque.

This assembly is mainly used when the axial force tending to separate the two parts is high. The machining of the key and its adjustment must be done with care, which explains why the cost of this...
