A method of manufacturing a universal joint includes: temporarily assembling a bearing, which supports a shaft portion of a joint spider such that the shaft portion is rotatable, with respect to a through-hole and the shaft portion by press-fitting the bearing to a first position in the through-hole of a yoke; and clinching, after the bearing is temporarily assembled, a portion of the yoke around the through-hole, and pressing the bearing deeper into the through-hole with a clinched portion formed by the clinching to press-fit the bearing to a second position located deeper than the first position in the through-hole.

A transmission shaft (1), designed particularly for a wind turbine, which is mounted by way of a fixed bearing (2, 3) and at least one floating bearing (4). At least one gearwheel (5) is fixed onto the transmission shaft (1) and positioned in the axial direction between the fixed bearing (2, 3) and the floating bearing (4). The fixed bearing (2, 3) is formed by at least one roller bearing and the floating bearing (4) is in the form of at least one slide bearing.

The invention relates to a device and a method for mounting a bearing 200 on a roll neck and for removing the bearing from the roll neck of a roll. Known devices of this type have a first and a second piston/cylinder unit. They also have a stop ring 130, fixed in the axial direction A at the end of the roll neck 320 remote from the body, which acts as a stop for the inner piston 110 of the first piston/cylinder unit. In addition, the known devices have a nut 150 which can be screwed onto an external thread of the inner piston to secure the bearing 200 in the axial direction, in particular during a rolling operation. As an alternative to the known prior art, the present invention provides that an annular cylinder 120 serves both as a cylinder for the first piston/cylinder unit and as a cylinder for the second piston/cylinder unit. For its function as a cylinder for the second piston/cylinder unit, said annular cylinder is covered to a certain ex ent on its side remote from the body by an annular cylinder cover 122. The cylinder cover 122 serves, together with an outer flange 142 of an outer piston 140, to axially delimit a removal pressure chamber 2 of the second piston/cylinder unit.

A bearing assembly may include a first bearing ring, a second bearing ring, and at least one row of rolling elements having a plurality of rolling elements that are disposed so as to be capable of rolling on a first raceway of the first bearing ring and on a second raceway of the second bearing ring. At least one hydrostatically supported first sliding bearing segment may be disposed on the first bearing ring. Further, the hydrostatically supported first sliding bearing segment may interact with a first bearing face that is disposed on the second bearing ring. The hydrostatically supported first sliding bearing segment may be mounted so as to be movable in a movement direction that is perpendicular to the first bearing face.

A propulsion system for a motor vehicle includes a casing having first and second housing portions cooperating with one another to define a cavity. The propulsion system further includes an electric motor disposed within the cavity. A support mechanism is attached to at least one of the first and second housing portions. The support mechanism includes a first side that faces the first housing portion and a second side that faces the second housing portion and is disposed within the cavity. Bearing seats are formed in the first housing portion, the second housing portion, and the second side of the support mechanism. Bearings are engaged with an associated one of the bearing seats and are configured to rotatably support the input member, the layshaft, and the output member in a fixed-free bearing arrangement. The first side of the support mechanism is free of the bearing seats and the bearings.
