Sealing bellows, transmission joint equipped with same and method for fixing same

摘要

A sealing boot intended to ensure the sealing of a transmission joint connecting two shafts. The sealing boot includes a boot body having a bead at each end to contact and seal the periphery of the shaft or an element of the joint integral with the shaft. Each bead includes a radial outer shoulder forming a transition between the bead and the boot body, and a bearing surface extending from the shoulder and adapted to receive an element for fixing the bead against the shaft or associated joint element. The bearing surface is extended without an increase in its external diameter as far as the end of the bead. The shoulder forms a stop for longitudinal positioning during the mounting of the fixing element.
