Design Accelerator calculates, designs, and performs strength checks of 4 pin joint types:
- Securing pin loaded with shear
- Cross pin loaded in a draw rod and a sleeve
- Radial pin loaded with torque
- Joint pin loaded with torque
Pins are designed without considering the effect of forcing into position. Stresses in shear, bending, and contact are evaluated.
Pins serve to make strong, detachable connections between 2 mechanical parts, to secure their positions accurately, and to eliminate transversal shifting forces. As a rule, standardized pins manufactured in a wide range of dimensions and designs are used. Prestress in the connection between parts is achieved either by means of pin allowance against the hole or the use of conical pins. Conical pins are self-locking and have taper ratio 1: 50. Cylindrical pins are produced as either plain or grooved.
- Holes for fitted cylindrical pins are drilled or reamed. The common fitting methods are H7/n6, H7/m6, H7/p6.
- Grooved pins do not require precise hole fitting and are more resistant to release. On the other hand, they are not suitable for connections that are dismantled frequently, or for connecting aluminum parts. The loading capacity of connections with grooved pins is approximately 20-30% lower. The H11/h11, H12/h11 fitting methods are most frequently used.
- Conical pins provide highly accurate and strong connections. They guarantee that the precise position of the parts being connected is maintained even after repeated connection disassembly. They are not suitable for connections subject to vibration and shocks. Holes for conical pins must be reamed in both parts simultaneously; the common fitting methods are H11/h10, H12/h11.
Pinned couplings are sized, under simplified assumptions, without allowing for the pressing effect and with reasonably reduced allowable stress. Connected parts are checked for deformation of contact surfaces on the hole face. Pins and clevis pins, depending on the connection type, are checked for shearing or bending stresses. As a rule, an additional check for shaft torsional stress is done in torque-loaded shaft-hub connections.
TipSee the Engineer's Handbook for allowable stresses of materials and other instructions for designing pin joints.
