Abstract
A method for making a casing () with protective bellows (A) for transmission device, such as a transmission joint, includes at least two shafts mobile axially and/or at an angle relative to each other, the casing () with bellows (A), whereon at least part of the bellows (') are radial, having at each open end a section (A,B) for being fixed to the transmission device. The method includes moulding the casing () with bellows (A), using a hollow mould and at least one core, having each at least a matching helical thread delimiting the moulding space and stripping the casing () formed by relatively unscrewing the casing () and the core to obtain a single-piece casing (). The invention is applicable to a casing with bellows by arrangement of extensible or flexible coupling elements.
