摘要:
Die Erfindung betrifft eine Kupplung von einer ersten Welle (2) mit einer zweiten Welle (6), die so ausgebildet ist, dass ein Kuppeln der ersten Welle (2) mit der zweiten Welle (6) erfolgt, wenn die erste Welle (2) eine höhere Geschwindigkeit hat als die zweite Welle (6), wobei ein Kuppelwinkel zwischen erster Welle (2) und zweiter Welle (6) durch die Kupplung (1) mechanisch vorgegeben ist. Die Erfindung betrifft ferner ein Verfahren zum Kuppeln einer ersten Welle (2) mit einer zweiten Welle (6), wobei eine Kuppeleinrichtung eingesetzt wird, mit der ein Kuppelwinkel zwischen erster Welle (2) und zweiter Welle (6) mechanisch vorgegeben ist, wobei zugleich eine Steuerung des Kuppelns durch Beeinflussung der Drehgeschwindigkeit der ersten Welle (2) und/oder der zweiten Welle (6), und/oder durch Beeinflussung des Kuppelzeitpunkts derart erfolgt, dass die Steuerung des Kuppelns das Erreichen des mechanisch vorgegebenen Kuppelwinkels unterstützt.

A sawing machine having a spindle (1) and circular saws (3) rotatably and axially slidably mounted on the spindle (1). A movable joint member (9) or a one-way clutch (30-32) is provided between the spindle (1) and the saws (3). While the spindle (1) is rotating at a low speed or at a stop, the joint member (9) or the clutch (30-32) is in its inoperative position, keeping the saws (3) disengaged from the spindle so that the distances between the adjacent saws can be adjusted freely. When the spindle (1) begins to rotate at a high speed, the joint member (9) is moved outwardly or the clutch (30-32) is engaged by centrifugal force, thus locking the circular saws (3) to the spindle (1).

Provided is a portable brush cutter with reduced weight and size due to its simple structure with a small number of components that is capable of improving durability and the like as well as effectively suppressing torsional vibration of a transmission shaft. In the portable brush cutter, a one-way clutch to prevent generation of torsional vibration in a rotation transmission path is interposed between an output shaft and a transmission shaft, and bearings are adjacently mounted on the opposite sides of the one-way clutch.

A driving force control system according to the present invention is for use in a vehicle which transmits motive power of a driving source to a driving wheel via a centrifugal clutch. The centrifugal clutch includes an upstream component mechanically connected to the driving source to rotate and a downstream component to be mechanically connected with or disengaged from the upstream component based on a centrifugal force which is in accordance with rotation of the upstream component. Transmission of motive power between an upstream-of-centrifugal-clutch path from the driving source to the upstream component and a downstream-of-centrifugal-clutch path from the downstream component to the driving wheel is automatically turned ON or OFF with a centrifugal force which is in accordance with rotation of the upstream component of the centrifugal clutch. The driving force control system controls the driving force of the driving wheel in the downstream-of-centrifugal-clutch path in accordance with a physical parameter concerning rotation of the upstream-of-centrifugal-clutch path, at least when the centrifugal clutch is in a half-clutch state.

A planar inertia-actuated overrunning coupling assembly having a pocket plate (76) and a notch plate (56) mounted on a common rotary axis with planar juxtaposed coupling surfaces. A pocket plate having a plurality of angularly spaced pockets (78) that receive adjustable clutch elements (94), the notch plate having angularly spaced notches (66), a clutch element being mounted in each pocket for pivotal movement about one edge thereof, an inertia-actuated ball (104) in each pocket adjacent a clutch element, the pocket being formed with a ramp surface engageable with the inertia-actuated ball whereby the clutch element is shifted into locking engagement with the pocket plate in response to an inertial force acting on the actuator balls whereby torque is transmitted from one plate to the other in one direction of relative rotation of the plates, and wherein the clutch elements move out of registry with the pocket plate upon reversal in the direction of relative rotation of the plates.

A clutch device includes a sleeve (30) which has recesses (31) and is engaged with an input shaft (20). Each of the recesses has a deep corner (311) and a shallow comer (312), and a roller (50) is received in each of the recesses. A driving disk (60) has a flange (61) enclosing the sleeve. A first ring member (70) and a second ring member (80) are mounted to the sleeve and each of the first ring member and the second ring member has slots (73, 84) which extend toward different directions. The slots in the first and the second ring member have a common space for receiving a ball (91) which is biased by a spring (92). An eccentric force shifts the balls and rotates the first ring member which has blocks (71) to shift the rollers to narrow comers to drive the driving disk.
