Abstract: A universal joint includes a first joint yoke and a second joint yoke having respective base portions. Each of the joint yokes has two yoke arms that are attached on the respective base portions. Each of the yoke arms ends in a free end and has an inner face facing toward the longitudinal axis and an outer face facing away from the inner face. Each of the yoke arms has a bearing bore extending between the outer face and the inner face. The inner face of each of the yoke arms has a first recess that is open toward the free end and that ends in the corresponding bearing bore. A journal cross assembly includes a journal cross having four circular cylindrical trunnions arranged at right angles toward each other, each trunnion supporting a bearing bushing having a cylindrical envelope face and a cylindrical bore. The bearing bushings are supported on the trunnions by rolling members.

Abstract: A universal joint includes two joint yokes that, respectively, have two yoke arms that each start from a connection portion. Through an eye portion distanced from the connection portion, bearing bores extend in which respectively, a journal of a journal cross by means of interposition of rolling members and of a bearing bushing are supported. On the outside of the yoke arms, a bulge is respectively provided towards the connection portion and adjacent to the bearing bore and over a partial circumference of the same, which bulge has, towards the bearing bore, a groove. A circumferential groove, belonging to a retaining trunnion projecting from the base of the bearing bushing, is arranged opposite to the groove. Between the two, a securing element is arranged that engages with an engagement portion in the groove and with a retaining portion facing away from the same, in the circumferential groove of the retaining trunnion.

Abstract: The invention relates to a fluid delivery device for shafts, with a shaft-ring section assigned to the shaft, which rotates with the shaft during rotation of the shaft and a ring body arranged around the shaft ring section, fixed during rotation of the shaft, which has an inlet for the fluid, rolling bodies being arranged between the shaft ring section and the ring body, on which the shaft ring section and the ring body are supported and a passage being assigned to the shaft ring section, which is connected to inlet.
