摘要:
A compact turning device for a heavy object, comprising a turning arm (11) joined to the heavy object (5) and a drive device (12) drivingly turning the turning arm (11). The drive device (12) further comprises a motor incorporating a rotor shaft connected to the rotating input part of a planetary gear type speed reducer on a same axis (A). Also, the turning arm (11) is installed by joining its first plane to the plane of the planetary gear type speed reducer forming the rotating output part and its second plane orthogonal to the first plane to the heavy object. The turning arm (11) and the drive device (12) are disposed within the width (D) of the heavy object (5) in the axis (A) direction of the turning pivot of the turning arm (11). The planetary gear type speed reducer of the drive device (12) may be disposed in two front and rear stages.

A reducer damage state notification device includes damage state notification means for sending notification relating to a damage state of a reducer, threshold value setting means for setting a threshold value for notification by the damage state notification means, and load receiving means for receiving a load which is applied to a reducer. The damage state notification means sends the notification relating to the damage state of the reducer corresponding to the threshold value when a color difference between a color detected by a color light reception element and a predetermined color reaches the threshold value. The threshold value setting means sets the threshold value according to the load which is received by the load receiving means.

It is aimed to provide a railway vehicle plug door device capable of easily ensuring airtightness between a side structure body and a door leaf even if the railway vehicle plug door device is installed in a side structure body having a structure assembled by joining structural members by welding and including a bent part. A frame body 12 is mounted on a part constituting an entrance 101 in a side structure body 100 by a mechanical fastening structure. A seal member 13 is mounted on at least one of a door leaf 11 and the frame body 12 and held in close contact with both the door leaf 11 and the frame body 12 when the door leaf 11 closes the entrance 101.
摘要:
Provided is a drive unit for a windmill that is configured such that even if excessive external forces act on one drive unit for a windmill when a plurality of drive units for a windmill are installed and used, possible breakage in the drive unit for a windmill can be prevented, and even in the case where a cutaway portion that serves as a mechanism for preventing breakage is provided, the operation of replacing the cutaway portion can be readily performed. A cutaway portion (19) is provided in a driving force transmission path and serves as a disconnection mechanism for disconnecting the driving force transmission path under the action of a torque of a predetermined magnitude or more, the driving force transmission path being a path through which a driving force is transmitted from an output shaft (14) to a pinion (13). A partitioning portion (20) is provided inside the body (11) and disposed between the cutaway portion (19) and a speed reduction portion (17) so as to partition an area between the cutaway portion (19) and the speed reduction portion (17).
