摘要： An inspection method is provided which allows an operating state of a rotating machine component such as a bearing to be easily inspected by using a dedicated sensor and a portable information terminal. A general-purpose portable information terminal (2), and a dedicated sensor (3) connected thereto are used. Detection data detected by the dedicated sensor (3) is transmitted from the terminal (2) to a server (6), and the server (6) performs data processing and transmits a processing result to the terminal (2). The terminal (2) displays the result on a screen (21a). A detection time period during which the detection data supplied by the dedicated sensor (3) has been detected at one time is less than one rotation of a rotating machine component (1). It is possible for an operator to determine a malfunction in the component (1) on the basis of a plurality of results.

摘要： A driving force transmission mechanism includes a worm gear unit as a brake disposed between a driving motor and an electrically driven input gear, and is configured such that when a driving force is applied from the driving motor to the electrically driven input gear through the worm gear unit, an outer ring which rotates together with the electrically driven input gear becomes locked to an inner ring through rollers so that the driving force is transmitted to an output gear, which rotates together with the inner ring, and when a driving force is applied to a manually driven input shaft, the outer ring and the inner ring are unlocked from each other by an unlocking piece which rotates together with the manually driven input shaft, and thereafter, the driving force is transmitted to the inner ring and the output shaft.

摘要： An electric lock includes an input switching clutch for selectively transmitting the electric or manual driving force to the output line. The input switching clutch includes an outer ring that rotates together with an electrically driven input gear, and an inner ring which rotates together with an output gear. Wedge-shaped spaces are defined between the outer ring and the inner ring. Two rollers are mounted in each wedge-shaped space and are biased toward the narrow portions of the wedge-shaped space by a coil spring also mounted in the wedge-shaped space. The input switching clutch further includes an unlocking piece having crossbars inserted at both circumferential ends of the respective wedge-shaped spaces, and coupled to a manually driven input shaft so that its rotation can be transmitted thereto; and a torque transmission mechanism for transmitting the rotation of the manually driven input shaft to the inner ring.

摘要： A device configured to actuate a driven member by driving a driving motor includes a brake which does not consume electric power and which can be easily mounted in the device. A speed reducer is mounted in the device, and includes a reduction mechanism for transmitting the rotation of the driving motor toward the driven member after reducing its speed, and a locking type reverse input shutoff mechanism, as the brake, which is configured to mechanically lock up when reverse input torque is applied from the driven member while the driving motor is not being driven, thereby retaining the position of the driven member. The reduction mechanism and the reverse input shutoff mechanism are combined to constitute a single unit.
