摘要： A roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and similar materials has a substantially horizontal grinding table (3) and a set of rollers revolving about a vertical shaft (5). The set of rollers includes a number of rollers (4) rotating about respective roller shafts (6) which are connected to the vertical shaft (5) via a hinged connection (7) which has a bearing shell (14) and a bearing journal (15) resting therein. The hinged connection (7) allows a free arcuate movement of the roller (4) in an upward and downward direction in a plane including the centerline (12) of the roller shaft. The set of rollers (4) is configured for interactive operation with the grinding table (3), and the bearing shell (14) of the hinged connection (7) has a diameter which exceeds that of the bearing journal (15) resting therein by a factor of at least 1 percent.

摘要： Described is a rolling bearing (1) for a rocker arm, said rolling bearing comprising an at least partly circular outer part (2), an at least partly circular inner part (3) and a number of rolling elements (5) which are fitted between the outer part (2) and the inner part (3). The rolling bearing is peculiar in that at least one of the rolling elements (5) comprises two opposite, curved side faces (6, 7), which viewed in at least one cross-sectional constitutes arc lengths of the same imaginary circle (10), and which constitutes contact faces for the outer and the inner circular part (2, 3) respectively, and at least one side surface (8, 9), which lies within the mentioned imaginary circle (10).It is hereby obtained that the number of rolling elements in the bearing can be increased, thereby reducing the load on each single rolling element subject to the same total load rate, thereby increasing the total load bearing capacity of the bearing. This is due to the fact that at least a part of the roller face of the traditional circular rollers which do not get into contact with the outer or inner part of the bearing through small reciprocating angular rotations is omitted thereby significantly reducing the space taken up by each of the rolling elements in the circumferential direction of the bearing.

摘要： A roller mill for grinding particulate material, such as cement raw materials, cement clinker and similar materials has a rotatable grinding table with a substantially vertical centerline and a number of rollers being configured for interactive operation with the grinding table and turning about separate roller shafts which are fixed to a rotatable center shaft with a substantially vertical centerline. The center shaft and the grinding table are fixed one to the rotor and the other to the stator of the same motor, which may have the capability of rotating both the grinding table and the center shaft.

摘要： Torsional vibration damper which is suitable for dampening the motion of a rotatable element, said torsional vibration damper comprising an ‘actuation’ element which is connectable to the rotatable element, an ‘inertia’ element arranged co-axially and rotatably with said actuation element, an enclosed volume between said inertia element and said actuation element where a cross section through said enclosed volume taken on a plane which is parallel to the axis of the actuation element comprises at least one ‘axial’ portion which is arranged essentially parallel to the axis of the actuation element, an Electro-Rheological or a Magneto-Rheological fluid arranged at least in a part of said enclosed volume, and an electric or a magnetic field generator in the form of a coil which generates an electric or a magnetic field which passes through at least a portion of said enclosed volume. The field generator is integrated into the torsional vibration damper in such a way that a majority of the magnetic or electric field lines generated by the field generator pass through said ‘axial’ portion of said enclosed volume. In this way, an effective torsional vibration damper is provided.
