摘要： Calender for the treatment of web-like materials, including a fixed structure supporting two heated rollers reciprocally arranged so as to form a nip traversable by web-like materials, where each roller has pins mounted on bearings. The structure includes two lower levers and two upper levers adapted for exerting on the bearings forces oriented according to not coinciding directions, each lever being connected with an actuator that controls its rotation around a horizontal axis to put it in a first engagement position of the respective bearing and in a second release position, such that in the second position of the levers the extraction of the rollers from the calender is allowed.

摘要： A fluid bearing assembly well-suited for use as high performance, web handling roller includes a stationary inner component that extends coaxially within a rotatable outer component. The inner component includes a single conical member from which extends a narrow stem. The delivery of fluid into a nominal gap between the inner and outer components creates a tapered bearing, with the outer component capable of frictionless rotation relative to the inner component. A thrust plate is axially mounted onto the stem and is retained thereon by a threaded nut. By delivering fluid into a nominal gap between the thrust plate and the outer component, a thrust bearing is created which counterbalances the net axial force produced from the tapered bearing. Furthermore, precise adjustment of the tapered bearing air gap can be achieved through rotation of the threaded nut, thereby enabling certain performance characteristics of the fluid bearing assembly to be modified.

摘要： A bearing alignment tool and method of use is provided for aligning inner and outer races of a roller bearing of the class wherein the inner and outer races of the roller bearing are axially displaceable with respect to each other in order to accommodate thermal growth of a rotating shaft. A bearing replacement procedure includes: (a) affixing the roller bearing to the shaft at its inner race; (b) disposing the shaft in a housing; (c) aligning the inner and outer races of the roller bearing with respect to each other and the housing in a predetermined spatial relationship by affixing an alignment tool to the housing, wherein the alignment tool has (i) an outer aligning surface which engages the outer race of the roller bearing; and (ii) an inner aligning surface which engages the inner race of the roller bearing; (d) removing the alignment tool from the housing; and (e) securing the housing to a fixed position on a support while maintaining the predetermined spatial relationship established in step (c). The method and alignment tool are particularly useful for quickly replacing bearings on an afterdryer of a papermachine where precision alignment and downtime are significant considerations.

摘要： A calender and an arrangement for mounting calender rolls, the calender comprising at least two calender nips (1, 2) formed by at least two stacked rolls (11–14). The rolls are have bearing housings (3–6) by means of which the rolls (11–14) are stacked into roll pairs forming the calender nips (1, 2), and means (31, 32) connecting the bearing housings (3, 4 and 4, 5) of the rolls pairs with each other. At least two successive calender nips (1, 2) are arranged so that in the successive nips the mutual distance between the longitudinal axes of the lower rolls (12, 14) is smaller than the corresponding mutual distance between the respective upper rolls (11, 13) of the nips, whereby the disposition of the rolls (11–14) forms a V-shaped angle as seen from the end of the calender machinery and thus forms an operating area between the nips for changing the rolls. The rolls are combined into nips advantageously using heatable pull rods inserted through the bearing housings.

摘要： The invention relates to an extra-roll slide bearing system (20) for a paper/board machine or a finishing machine, surrounding a shaft (2) in a roll (1). The bearing system comprises a body section (5), which is formed with a bearing housing (7) provided with hydrostatic bearing elements (3, 3A) disposed around the shaft (2). The bearing elements are fitted with slide elements (4, 4A), having a sliding surface (16) directed towards the shaft (2). Between the slide elements (4) and the shaft (2) is a bushing (6), which is mounted on the shaft (2) for rotation therewith, said slide elements (4, 4A) being adapted to position themselves around the bushing (6) with the sliding surfaces (16) against the external surface of the bushing directed away from the shaft for supporting said shaft (2), and hence the roll (1), rotatably relative to the body section (5). The bearing housing (7) has its axial ends provided with end caps (8, 9), along with packing elements (12, 14) therefor, for sealing the bearing housing. The slide bearing system (20) of the invention is assembled for a single package, which is mountable on the shaft (2) and dismountable from the shaft (2) as a single package.

摘要： A deflection compensated roll has a stationary support structure and a shell rotatably arranged around it by means of slide bearings. The shell is additionally supported on the support structure with hydraulic loading devices by which the axial profile of the shell can be controlled. In the procedure, at least the pressure acting in the main bearing elements of the slide bearings effective in oppsite directions in the nip plane is measured by conducting pressure data from a pressure space between a control valve associated with the main bearing elements and each main bearing element by means of measurement ducts outside the roll where the pressure data is passed to a pressure sensor.
