Calculation basis: G. Niemann, Maschinenelemente, volume I, 1981. Calculation of the solder connection is executed for connections that are stressed on shear.
Two different stress cases are provided:
Shear force: Transmission of a shear force between two surfaces
Torque: Shaft-hub connection with torque stress.
The connection can be stressed statically or dynamically (in the normal case pulsating). The following can be selected as materials (extensible database):
Soft solder LSn40, LSn60, peak load
Soft solder LSn40, at continuous load
Brass solders: Steel NE heavy metals
Argentium silver solders, copper: Steel
Silver solders: Steel NE heavy metals
Sizing of solder width for (shaft/hubs) or solder length (for brackets) due to the strength of the base material. The tensile strength of the connection is sized in such a manner that it corresponds to the tensile strength of the base material, or the fatigue strength of the shaft.
Sizing of the solder width based on stress: Tensile strength of the connection is sized in such a manner it can transmit the acting forces taking the entered target resistance into account.
