A power transmission device includes a pulley (4) and a hub (11) that are arranged on the same rotation axis, and a connecting member (13) that connects these rotation bodies. The power transmission device includes a first connecting structure (14) that connects one end portion (13a) of the connecting member to the pulley so that one end portion (13a) cannot be separated, and a second connecting structure (15) that connects the other end portion (13b) of the connecting member to the hub so that the other end portion (13b) can be separated. The second connecting structure includes a columnar body (21) that extends through the other end portion (13b) of the connecting member (13) in the axial direction, a head portion (28) that is provided on the columnar body (21), a slit (22) of the connecting member (13), and a belleville spring (29) that presses the connecting member (13) against the rotation body. The other end portion (13b) of the connecting member (13) is formed to be larger than the remaining portion of the connecting member (13) when viewed from the axial direction. A recessed portion (16) that is recessed toward the outer peripheral side of the hub (11) is formed at a portion of the other end portion (13b) that is directed to the shaft center side of the hub (11). The power transmission device capable of setting with high accuracy the operation load of a torque limiter that cuts off power transmission can be provided. |

L'invention a pour objet un mécanisme d'accouplement entre un organe de commande (1') générateur de commandes de vol manuelles et un vérin de « trim » (4) équipant une chaîne de transmission mécanique de commandes de vol d'un aéronef. Le mécanisme d'accouplement comprend des moyens de brochage axial entre un bras de levier (3) mécaniquement lié à l'organe de commande (1') et un arbre pivotant (10) que comprend le vérin de « trim » (4). Les moyens de brochage axial comprennent des organes d'emboîtement (13,14) coopérants ménagés sur des organes d'accouplement (18,19) liés respectivement en rotation avec le bras de levier (3) et l'arbre pivotant (10). Les organes d'accouplement (18,19) comportent chacun des couloirs (26) axiaux de circulation à leur travers de l'autre organe d'accouplement (18,19). Une rupture dudit brochage axial provoque un déplacement axial relatif entre les organes d'accouplement (18,19) l'un à travers l'autre sous l'effet d'une poussée (P) axiale exercée par des moyens à déformation élastique (15) exploités pour procurer ledit brochage axial.

| A power transmission device in which a driven body and a driving body for driving the driven body are rotated in the same direction and are connected together by a connection section to transmit torque of the driving body to the driving body and in which the transmission of the torque from the driving body is interrupted when a drive load on the driven body exceeds a predetermined level. The connection section is constructed by combining separate elements that are a positive torque transmission member, and a negative torque transmission mechanism or a negative torque transmission member. The positive torque transmission member transmits torque in the normal rotation direction and interrupts transmission of torque from the driving body by breaking itself when a drive load on the driven body exceeds the predetermined level. The negative torque transmission mechanism or the negative torque transmission member can transmit torque in the reverse rotation direction. In the power transmission device, fatigue of materials of the connection section is suppressed and torque is accurately interrupted at a desired interruption torque value. | ||||||

| A power transmission mechanism capable of connecting a drive source to a compressor so that a power can be cut off, comprising a pulley rotated in synchronous with the drive source and a bearing member rotated in synchronous with a drive shaft of the compressor, wherein a limit spring connects the pulley integrally rotatably with the bearing member, when a load torque of the compressor exceeds a specified value, the limit spring is reduced in diameter and engaged with a rib provided on the bearing member, and the deformation of the limit spring in radial direction is limited locally and a stress is increased suddenly at a specific position of the limit spring, whereby the limit spring is broken positively near a desired load torque so that a satisfactory power cut off can be realized. |

| 148 | DECOUPLER SHAFT | EP89910517.5 | 1989-09-15 | EP0441796B1 | 1994-06-15 | LAESSLE, David, L.; CARLSON, Todd, Steven; KROCHMALNY, Andrew, John; ANDERSON, Leroy, C. |
| A torque limiting decoupler shaft (58) transmits driving torque in a first sense without torque limiting action. However, torque applied to the shaft in a reverse sense opposite the driving torque results in an axial separating force between two portions (64, 66) of the decoupler shaft (58). When the reverse torque reaches a certain level a frangible tensile bar member (82) fractures to permit decoupling of the shaft portions. A component (70, 80) of the shaft prevents undesirable recoupling of the shaft portions (64, 66) while also insuring that the relatively rotating portions of the shaft do not flail. An air turbine starter (10) includes such a decoupler shaft (58). | ||||||

Die Erfindung betrifft eine Sicherheitskupplung zur Zwischenschaltung zwischen Handhabungsgerät (1) und Greifer (3). Von den bisher bekannten mechanischen Lösungen mit vorgespannten Federn und Führungsteilen wird kein Gebrauch gemacht, sondern die Arretierung der Sicherheitskupplung erfolgt über Permanentmagnete (8). Diese Permanentmagnete (8) werden auf der dreiteilig ausgeführten Sicherheitskupplung entweder auf einem Flansch (2;4) oder auf einem Zwischenring (7) angebracht. Sie sind zweckmäßigerweise paarig und gleichmäßig über den Umfang der Flanschen (2;4) angeordnet. Entsprechend der winkeligen Anordnung eines Permanentmagnetenpaares sind als Gegenstücke senkrechte Prismen vorgesehen, die jeweils in ein Paar von Permanentmagneten hineingreifen und somit die Sicherheitskupplung arretieren. |

Driving and driven members are coupled by a shaft having a thin wall portion (13). A severing tool (40) is pivotally mounted at one end and a spring urges the tool towards the shaft. A solenoid-controlled latch (60,61) normally holds the tool away from the shaft. Energisation of the solenoid (60) releases the tool (40) to enable the spring to force the tool to engage the shaft to cause localised heating of the thin wall portion to sever the shaft. A spring-loaded conical point bearing within the shaft maintains separation of the severed shaft portions. The device is useful for rapid disconnection of a high speed generator from an air-craft engine, while permitting simple replacement and resetting. |
