Abstract: The invention concerns a switchable locking element freewheel with two concentric cage rings and locking elements lodged in pockets thereof, the cage rings being movable relative to each other for switching the freewheel. In order to make such a freewheel basically operable in two opposing directions and to provide simple switchover facilities herefor and also for cases in which switchability is required only in one direction, the relative movement of the two cage rings serving to switch the freewheel is an axial displacement which, with a view to any further embodiments of the freewheel, can be converted into a rotary movement.

Abstract: A freewheeling device (11) for torque transmitting purposes at small numbers of revolutions, e.g. at low driving speeds, has two freewheeling parts (14, 17) connected via locking members (25). The locking members (25) engage apertures (24) of one of the freewheeling part (17) and recess (26) of the other freewheeling part (14). If a certain speed of the two freewheeling parts (14, 17) is exceeded, one freewheeling part (14) may overtake the other freewheeling part (17). Switching is effected via a switching cage (29) loaded by centrifugal masses (33) and which moves a switching element (30) into the released position. A spring (36) ensures the transfer into the locked position. A synchronizing device (38) is provided in order to ensure that a transfer into the locked position takes place only at small speed differentials between the two freewheeling parts (14, 17).

If the speed is below the specified speed, an additional switching element is released via a speed-dependent switching device 29, so that the switching element 30, under the influence of a spring 36, is transferred into a position where it supports the locking member 25 to prevent them from escaping radially inwardly, thereby cancelling the freewheeling function.

The angle of the notch and the pin taper are chosen to effect a positive de-energization force on the pin for facilitating disengagement.

The radially outward movement of the balls is caused by a sleeve cam telescoped upon the second shaft. The sleeve cam can be moved axially by a yoke arrangement, which is controlled by a lever located outside the housing.

Abstract: The disconnect arrangement for high speed aircraft generators includes disconnectable rigid, torque transmitting spring loaded curvic gears coupled between the driving and driven shafts. A plurality of flexibly supported sear members mounted on the driven shaft engage the movable member of the curvic gears. The sears have tapered faces which engage correspondingly tapered shoulders on the movable curvic gear member.

When the electromagnetic armature is actuated to disengage the driving and driven shafts, the armature moves axially. This removes the retaining force from the tapered sears, allowing them to flex outwardly.
