    Abstract: A winch (1) for a ship comprises a frame (2), a drum (3) which is mounted to the frame (2) through at least a bearing (5) and rotatable with respect to the frame (2) about an axis of rotation (X), a cable (4) which is wound around the drum (3) and a brake (6-8) for locking the drum (3) with respect to the frame (2). Under operating conditions a part of the cable (4) that extends outwardly from the drum (3) exerts a cable force (Fc1, Fc2) on the drum (3) and lies in a cable plane (P) which extends tangentially with respect to the drum (3), hence causing a torque about the axis of rotation (X) whereas the brake (6-8) exerts a counter torque on the drum (3). At least one of the frame (2) and the drum (3) is provided with a plurality of sensing probes (10) for determining local deformation of the at least one of the frame (2) and the drum (3), which sensing probes (10) are located at different angular locations around the axis of rotation (X).

    Abstract: In a downhole motor bearing section having a cylindrical mandrel rotatably disposed within a cylindrical housing, a bi-directional thrust bearing is disposed within a four-shouldered annular containment chamber formed partially into the inner cylindrical wall of the housing and partially into the outer cylindrical wall of the mandrel. Under on-bottom loading conditions, thrust loads are transferred through the thrust bearing by the upper shoulder of the housing and the lower shoulder of the mandrel. The radial widths of these two shoulders are both symmetrical about the centerline of the thrust bearing such that on-bottom thrust loads are transferred non-eccentrically to the thrust bearing, thereby avoiding twisting loads on the thrust bearing races, increasing the effective on-bottom load capacity of the thrust bearing and extending its service life.

    Abstract: In the rolling bearing device with a sensor in this invention, a band-shaped film 111 having insulation property is affixed to an outer circumferential surface of an outer ring 101 so as to extend in the circumferential direction. On the film 111 is affixed a foil 112 composed of identical four portions and having electrical conductivity which are placed at generally equal intervals in the circumferential direction of the outer ring 101. A resistance between a first place and a second place of the foil 112 is measured by a resistance measurement section of a microcomputer. A preload calculation section of the microcomputer, upon reception of an output from the resistance measurement section, calculates a preload of the outer ring 101 based on the measured resistance.
