摘要： A volume flow regulating valve for controlling the volume flow of a fluid medium in two outflow ducts. The volume flow regulating valve is composed of a cylinder with a dual piston mounted axially displaceably in the cylinder, with a central pressure chamber being formed in the region of the barbell-shaped central piece of the dual piston. Aside from an inlet for the fluid medium, it is also the case that the two outlet ducts are provided at the central pressure chamber. The outlet ducts are arranged on the cylinder with such an axial spacing that—when the dual piston is situated in a central position in relation to the two outlet ducts—the first outlet duct—preferably partially covered by the first piston—and the second outlet duct—preferably partially covered by the second piston—each open up an equal opening cross-sectional area.

摘要： 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.

摘要： To increase the load-carrying capacity or rolling capacity of a roll assembly in a rolling mill, throttle elements are used, which shut off the lateral flow of the lubricating film in a partial region between the roll neck and the bearing surface of the roll neck bearing assembly, thereby bringing about an increase in pressure in the lubricating film. At least one throttle element is embodied as an annular segment, forming an angular shut-off region for the lubricant in the annular gap. The invention makes it possible for existing installations to be easily retrofitted, without the need for structural modifications. In the case of new installations, the same load-carrying capacity as before can be provided while the dimensions of the installation space are reduced. The load-carrying capacity of the bearing assembly can be flexibly adjusted based on the dimensions of the shut-off region for the flow of lubricant.

摘要： The invention relates to a rolling stand for the rolling of metallic rolling stock. The rolling is achieved with the aid of a roll of which the two roll journals (112) are rotatably mounted in recesses (122) of chocks (120). The recesses are supplied with coolant and/or lubricant via a high-pressure inlet (124) and at least one low-pressure inlet (126). The high-pressure inlet is fed via high-pressure conduits (132) from a high-pressure pump (130). To reduce the costs for driving the high-pressure pump in relation to the prior art, the invention provides that the high-pressure pump is rotationally coupled to the roll journal via a gear mechanism in order to be driven thereby.

摘要： The invention relates to a roll arrangement for use in metallurgical technology, comprising a roll that has a roll barrel and two roll necks, and at least one neck bushing for accommodating at least one of the roll necks in a rotationally fixed manner. A carrier element that functions as a form-locking rotationally fixed connection is arranged between the roll neck and the neck bushing. In order to increase the load-bearing capacity of the roll bearing without increasing the size of or the mounting space for the roll bearing and at the same time ensure easy assembly, the roll neck is mounted in the neck bushing with some radial play such that a circumferential cavity is formed between the neck bushing and the roll neck in the unloaded stated as a result of the radial play. In order to increase the size of the cavity, the roll neck or the inner surface of the neck bushing additionally has a concave contour or profile.
