Abstract: A method for joining a ring member, e.g. a bearing inner race ring, to a shaft so that the ring member is primarily prevented from axial motion relative to the shaft involves arranging the ring member over the shaft so that the shaft extends through a bore in the ring member, and applying between the ring member and the shaft a clamping wedge force in which a tapering locking surface acts against a substantially corresponding tapering surface. The device for joining the ring member to the shaft includes a locking member mounted on the ring member and provided with a tapering contact surface that faces towards the shaft. An arrangement is provided for pressing the locking element against a tapering counter surface that is fixed in position relative to the shaft to prevent axial movement of the ring member on the shaft.

Abstract: A device for changing a roll disk arranged in a free-floating fashion on a roll shaft and braced against a shoulder of the roll shaft, the device including a roll shaft piece connectable to an end face of the roll shaft and having radially projecting claws. An installation-and-removal unit is placeable on and coaxially turnable to the roll shaft. The unit has radially extending first, second and third claws that form perimeter segments. The first claws correspond to and engage with the claws of the roll shaft piece. A taper bushing is slidably provided between the roll disk and the roll shaft to hold the roll disk on the roll shaft, and has radially extending claws. The second claws correspond to and engage with the taper bushing claws, and are also moveable axially to the roll shaft. A ring is coaxially mounted on a side of the roll disk facing the unit, and has radially extending claws that correspond to and engage behind the third claws. All the claws have a perimeter extension whereby the corresponding claws lie perimetrically next to one another in a plane seen in the axial direction when the unit is placed on the roll shaft. The unit is turnable between a first position in which the claws of the roll shaft piece and the taper bushing respectively engage with the first and second claws, and a second position in which only the claws of the ring engage with the third claws.

Abstract: A bearing assembly for a roller of, for example, a steel rolling mill, comprises an inner bush with a conical bore to receive tightly a conical pin projecting from the roller, an outer bearing bush rotatably surrounding the inner bush but axially captive, and a holder to which the outer bush is fixed. The bearing assembly further includes a hydraulic jacking arrangement for forcing the bearing assembly over the conical pin of the roller and withdrawing it again. In one example the fluid pressure operable means is a double acting cylinder arrangement comprising an inner cylinder surrounding an extension of the roll pin and arranged to abut against a stop at the end of the extension, a collar surrounding the inner cylinder and sliding within an outer cylinder which has an external flange at its axially outer end arranged to engage a flange of a part rigid with the bearing holder. The spaces on either side of the collar between the two cylinders form pressure chambers and are closed at the axially outer ends by an L-shaped bush and at the axially inner end by a reduced diameter portion of the outer cylinder. Fluid pressure connections lead to the two pressure chambers. Two other examples are described in which separate cylinders are used for mounting and withdrawing the bearing rather than a double acting cylinder as in the first example. The various parts have discontinuous flanges in the form of a series of radially projecting lugs which can be engaged together by giving one part a part-turn relative to the other in the manner of a bayonet catch.
