摘要： In a bearing preloading device in which a compression coil spring is used, a hole is defined in a bearing race or in a separate member axially opposed to the bearing race. The hole has an inner periphery constituted by a threaded portion connected to a bottom surface of the hole, and a shallow hole portion connected to an edge of the hole. An inner diameter of the shallow hole portion is larger than an inner diameter of the threaded portion.

摘要： A split ring for use in assembling a bearing retainer onto a roll. The split ring helps keep a mounting jack in compression with the bearing retainer as the mounting jack compresses the bearing retainer onto the roll. In some embodiments, the split ring includes a plurality of apertures that are each configured to receive a drive mechanism that helps collapse the mounting jack to allow for removal of the split ring and the mounting jack once the bearing retainer is assembled onto the roll.

摘要： It is desired to prevent generation of negative pressure in a bearing space and to prevent entry of foreign matter such as water into a bearing. The bearing includes an inner race (1), an outer race (3), rolling elements (5) disposed between raceways (2 and 4) of the inner and outer races and retained by a retainer (6), and seal assemblies (7) provided at the respective ends of the outer race (3). Each seal assembly (7) includes a seal case (9) fitted on one end of the outer race (3), and an oil seal (11) mounted in the seal case. A check valve (20) is mounted in the seal case (9) and allows only a flow of gas from outside the bearing into the bearing space. A filter (29) is mounted in a flow passage in the check valve and allows passage of gas and prevents passage of liquid and solids.

摘要： A method for assembling a set of bearing assemblies 100 onto a mill roll 10 and for establishing a required bearing setting. The mill roll 10 is configured to receive a set of bearing assemblies 100 at each axial end, with the bearing rolling elements 100A contained within supporting chocks 102 adapted for placement within a mill housing. The chock assembly 102R and bearing assembly 100 at a first end of the roll are positioned first, and coupled to the first end an axial center rod 22 passing through an axial bore 24 of the roll 12. The chock assembly 102L and bearing assembly 100 at the second end of the roll 12 is then positioned onto the opposite end of the roll 12, and a connecting sub-assembly 300, 400, 504A is secured to the second end of the axial center rod 22. The connecting sub-assembly engages the second chock assembly 102L and bearing assembly 100, and is adjusted to achieve a desired bearing setting for both bearing assemblies 100 through the center rod 22.

摘要： A system is disclosed for use in a rolling mill oil film bearing to remove a laminar flow of oil exiting tangentially from between a rotating sleeve and a fixed bushing surrounding the sleeve. The system comprises confinement surfaces cooperating with the sleeve and the bushing to define an annular chamber arranged to receive the exiting laminar flow of oil. Impellers project into the chamber and are rotatable with and at the velocity of the sleeve to thereby propel the oil around the annular chamber. An outlet communicates tangentially with the annular chamber for removing oil being propelled around the chamber by the rotation of the impellers. The size of the outlet in relation to the volume of oil received in the annular chamber is such that the chamber remains filled with oil during steady state operation of the bearing.

摘要： A lubrication delivery system for a rolling facility having a plurality of roll stands. A centralized lubrication source is arranged to supply lubrication to a plurality of liners within the roll stands during a rolling campaign. The lubrication source can supply one or more lubricants via controlled conduits in fluid communication with the liners. Liners are provided with a plurality of conduits for directing pressurized lubricant from the centralized lubricant source so as to minimize lubricant loss. A plurality of different lubricants may be provided at a centralized source with a controller or other device directing a flow of pressurized lubricant to the plurality of roll stands during the campaign.
