Oldham coupling i used to connect two shafts having intersecting axes.
A machine started malfunctioning due to some issues with the coupling. The coupling emplaced in the machine was Oldham. The only coupling available in the workshop is Hooke’s coupling. So Oldham coupling can be replaced by Hooke’s coupling.
A muff coupling is connecting two shafts. The torque involved is 650N-m. The shaft diameter is 45mm with length and breadth of the key being 14mm and 80mm respectively. Find the shear stress induced in the key.
The region of safety for biaxial stresses is of which shape in the case of maximum distortion energy theorem.
Distortion energy theorem is not recommended for ductile materials.
Among maximum shear stress theory and distortion energy theory, which gives the higher value shear yield strength?
A muff coupling is connecting two shafts. The torque involved is 650N-m. The shaft diameter is 45mm with length and height of the key being 14mm and 80mm respectively. Find the compressive stress induced in the key.
