Abstract
A mechanical duty bellows seal is constructed from a number of annular rubber diaphragms of comparatively thick cross-section alternately bonded to a series of outer and inner metal hoops so that the hoops hold the rubber diaphragms in simple shear during flexure of the bellows. The stresses in the rubber in shear are predictable thus allowing the calculation of diaphragm proportions to control stress levels.
