  • Patent number: 11391325
    Abstract: In order to enable a bearing system in which a plurality of bearings operate simultaneously or in association with each other to achieve an optimal overall performance: this bearing system is equipped with a bearing A and a measurement execution unit A therefor, a bearing B and a measurement execution unit B therefor, and a control unit for controlling the measurement execution unit A and the measurement execution unit B; the control unit transmits an instruction to the measurement execution unit A and the measurement execution unit B to enable execution of the performance required of the bearing system. The measurement execution unit A and the measurement execution unit B respectively operate the bearing A and the bearing B under an instructed operation condition.
    Type: Grant

  • Patent number: 10948010
    Abstract: A bearing device includes a base plate, a plurality of sliding pads and support members. The sliding pad is movable relative to the base plate. The support members are located between the base plate and the sliding pad, and shift a position of a load supporting point in a circumferential direction of the base plate, the load supporting point serving as a point for supporting a load received from the sliding pad. When any virtual flat surface perpendicular to a rotating shaft member is considered as a reference surface, and when a distance from the reference surface through the load supporting point to an end of the sliding pad at the opposite side to the base plate is defined as a setting distance, a position of the load supporting point is shifted in a circumferential direction of the base plate with no change in the setting distance.

  • Patent number: 10240630
    Abstract: A leveling plate including a main body and an end protrusion. The end protrusion is provided at both ends in a longer side direction of the main body, and protrudes from the main body in a thickness direction, the end protrusion having an end circumferential surface whose central axis extends in parallel with a shorter side direction of the main body.
