摘要: A shaft assembly may include two or more Poka-Yoke bearing caps, each Poka-Yoke bearing cap having a pair of reference bores offset from a central axis of the bearing cap by differing offset distances, and each bearing cap defining a semi-circular recess that is positioned so as to align in use a central axis of the semi-cylindrical recess in the bearing cap with an axis of rotation of a shaft rotatably supported by the bearing cap. The differing offsets of the reference bores prevent the bearing cap from being assembled in a reversed orientation. To ensure that each bearing cap can only be fitted in one position, a centre spacing between the first and second reference bores of each bearing cap is different to the centre spacing used for other bearing caps used to support a single shaft.

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: A solid film of a fluorine-containing polyurethane polymer is formed on at least one of the constituent elements (inner and outer rings, rolling member and retainer) of a rolling-contact bearing. The molecules of the solid film of the fluorine-containing polyurethane polymer have urethane bonds, and form a three-dimensional reticular structure. Therefore, the film is unlikely to separate, peel off or wear. The occurrence of the dust can be restricted, and lubrication property can be improved.

摘要: A spindle is rotatably mounted within a housing on spaced-apart antifriction bearings. The inner races of the bearings are held solidly against shoulder portions of the spindle and the outer race of the front bearing is mounted against a shoulder in the housing. The outer race of the rear bearing is supported in a circular diaphragm concentric with the spindle axis, which may be flexed along the axis to load the bearings against one another. A hydraulic chamber is formed against the diaphragm to load the diaphragm at preselected intervals, and a stop plate is provided in the housing to limit movement of the outer race is a distance corresponding to a maximum preload in the bearings. When the stop plate is contacted, hydraulic pressure may be greatly increased to further load the diaphragm and its corresponding outer race solidly against the stop plate without further increasing the preload in the bearing set, providing a high holding force resistant to spindle pull out.

摘要: The spindle device of the present invention is of the type wherein a shaft is carried by ball bearings or tapered roller bearings in a front side and a rear side, and a preload is applied by a spring. A gimbal ring is inserted between an outer ring of the front side bearing and a shoulder face of a housing on which the outer ring is mounted. With this construction, the axial and radial deviations of the shaft can be minimized.

摘要: A bearing device for a spindle (12), rotatably suspended in a frame (1), comprises a first bearing (4) arranged to transfer radial forces from the spindle to the frame while permitting a certain inclination of the spindle in relation to its intended rotational axis (A), and a second bearing (3) arranged to transfer axial forces from the spindle to the frame. For avoiding mutual inclination of the bearing rings of the axial bearing (3) upon inclination of the spindle during its operation, said axial bearing (3) is arranged to transfer the axial forces through two abutting contact surfaces movable relative to each other, one of which is united with the rotatable bearing ring (13) of the axial bearing, and the other of which is united with the spindle (12).
