摘要： A power transmission apparatus comprising a pulley 1 and a hub 2 is disclosed. The hub 2 includes an inner hub 21 fixed on a rotary shaft 4 and an elastic member 23 coupled over a joint length L to the outer periphery of the inner hub 21. Elastic member 23 includes a hub-side engaging portion having a series of protrusions arranged in a ring and a cylindrical portion connecting the hub-side engaging portion and the inner hub. Pulley 1 has a pulley-side engaging portion having a series of depressions fitted on the hub-side engaging portion. The engagement between hub-side engaging portion 235 and pulley-side engaging portion 14 forms a torque transmission structure of hub 2 and pulley 1. An axial length TL of a torque transmission surface TS formed by hub-side engaging portion 235 and pulley-side engaging portion 14 in contact with each other is larger than joint length L between the cylindrical portion and inner hub 21. Axial length TL, when projected in the radial direction, is partially overlapped with joint length L.

摘要： A coupling device has a pulley that receives rotational torque from an engine. The torque is transmitted to a shaft through a hub and a one-way clutch. A torque limiter is screwed on the shaft to fasten the inner ring of the one-way clutch onto the shaft. The torque limiter has a breakable portion. The torque is directly transmitted from the inner ring to the shaft when the torque is normal. If the torque exceeds the tightening torque of the torque limiter, the inner ring begins to slide and rotate, and drives the torque limiter in a tightening direction. As the torque limiter is tightened additionally, the tensile stress on the breakable portion is increased. Then, the breakable portion breaks and is separated in axial direction so that the coupling device disconnects torque transmission.
摘要翻译：联接装置具有从发动机接收旋转扭矩的滑轮。扭矩通过轮毂和单向离合器传递到轴。扭矩限制器拧在轴上，将单向离合器的内圈固定在轴上。扭矩限制器具有易碎部分。当扭矩正常时，扭矩从内圈直接传递到轴上。如果扭矩超过扭矩限制器的拧紧扭矩，内圈开始滑动并旋转，并沿紧固方向驱动扭矩限制器。当额定扭矩限制器被紧固时，可断裂部分的拉伸应力增加。然后，可破坏部分断裂并在轴向方向上分离，使得联接装置断开扭矩传递。

摘要： A power transmission device includes: a pulley 1 rotatably attached to a casing 9; a hub 2 connected to the pulley 1 by an engagement of protrusions with recesses; and a power shutoff member 3 interposed between the hub 2 and a rotary shaft 4. The power shutoff member and the rotary shaft 4 are joined to each other by means of screwing. When a water intrusion path formed between a hub side seating face of the hub and a shaft side seating face 44 of the rotary shaft is formed into a labyrinth structure, water is prevented from entering the seating face. An engagement portion 35 on the power shutoff member side is engaged with a hub side engagement portion 21a so that it can be accommodated in the hub side engagement portion 21a, and the power shutoff member can be rotated together when the hub is rotated. An engagement gap formed between a power shutoff member side engagement portion and a hub side engagement portion in the radial direction perpendicular to an axis of the rotary shaft is in a range from 0.001 mm to 15% of a diameter of a circumscribed circle of the power shutoff member side engagement portion.
