摘要： A brake cylinder device is provided that can prevent an unintentional release of a braking force of a spring brake means due to disengagement of meshing portions of a clutch mechanism. A brake cylinder device (1) includes a service brake means (11) including a first piston (24), a spring brake means (12) including a second piston (27), a clutch mechanism (14), a spindle (15), and a spindle holding means (16). The spindle (15) is connected to the first piston (24) so as to be rotatable about an axial direction. The clutch mechanism (14) includes a nut member (33) that is supported rotatably by the second piston (27) and screwed to the spindle (15), and connects or disconnects the spindle (15) and the second piston (27). The spindle holding means (16) restricts the rotatable angle of the spindle (15), and holds the spindle (15) with respect to the first piston by urging the spindle (15) in a direction that is opposite to a rotation direction in which the nut member (33) is deeply screwed to the spindle (15).

摘要： A recycling passage 71 is configured to perform "pressure oil recycling," in which the recycling passage 71 feeds boom discharge oil 35Fo (recycling discharge oil) discharged from a boom cylinder 23F (a recycling actuator), to the boom cylinder 23F (an actuator actuated with feeding of discharge oil from a second pump 12). A first sensing pressure rising passage 81 feeds a part of boom discharge oil 35Fo to a first unload passage 31 upstream of a first pressure sensing unit 61p when the pressure oil recycling is performed.

摘要： Provided is a wind turbine driving device in which the wear amount and a malfunction of a friction plate can be easily detected. A pinion 25a of an output portion 25 meshes with a ring gear 107 of a wind turbine 101. A first friction plate 29 is coupled to an output shaft 22a of an electric motor 22 at an end of the output shaft 22a situated further from a speed reducer 24. A second friction plate 30 contacts with the first friction plate 29 and serves as a brake on the output shaft 22a. Elastic members 31 bias the second friction plate 30 toward the first friction plate 29. Electromagnet 32 biases the second friction plate 30 in the direction in which the second friction plate 30 is separated from the first friction plate 29. A detector 34 detects a position and a displacement of a detection target portion 33 fixed on the second friction plate 30. Based on a result of detection performed by the detector, operation of the second friction plate 30 is detected and checked, and the wear amount of the first friction plate 29 and the second friction plate 30 is detected.

摘要： A carrier is supported by a case via a bearing. The bearing comprises an inner race, an outer race, a plurality of rollers, and a retainer. The inner race has a tapered outer peripheral surface, and is fixed to a carrier. The outer race has a tapered inner peripheral surface facing the outer peripheral surface of the inner race, and is fixed to the case. The plurality of rollers is disposed between the inner race and the outer race. An end part of the retainer having a larger diameter makes contact with the case via a first member. The larger diameter end part of the retainer makes contact with the case via a second member. By the retainer making contact with the case and the carrier via the first member and the second member, the retainer can reduce friction compared to when making direct contact with the case and the carrier.
