Pin Component Generators

Design Accelerator calculates, designs, and performs strength checks of 4 pin joint types:

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.

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.

Tip: See the Engineer's Handbook for allowable stresses of materials and other instructions for designing pin joints.
