Abstract
A flexible coupling is provided to connect a flange on a drive shaft to a flange on a driven shaft. Circumferentially spaced fastening means provide bores through the coupling through which bolts can be passed to connect it alternately to the one and then the other flange. Adjacent fastening means are interconnected by link and washers are positioned at opposite ends of the stack of links at each fastening means. In accordance with the invention the washers are formed with peripheral grooves which will be entered by the plastics material forming the body of the coupling, thus locking the washers against being expelled when bolts are subsequently passed through the bores.
Claims10
A flexible coupling for connecting a drive to a driven shaft, the coupling comprising an annular body of a mouldable material in which fastener means are incorporated whereby the coupling may be fastened to the shafts, the fastener means comprising an even number of parallel bores circumferentially distributed about said body, each bore opening to opposite sides of the body, a plurality of link means passing around each bore and extending at least one to the adjacent bore in one direction from said first-mentioned bore and at least one to the adjacent bore in the other direction from said first-mentioned bore, and washer means on opposite sides of said link means defining end orifices of each bore, each washer means having a peripheral formation such that when the body is moulded to incorporate the fastener means and link means each washer means will be locked by the moulded material against displacement out of said body.
