摘要： A two-way clutch comprising an input system rotational member (10) adapted to be rotatably driven by a driving source, an output system rotational member (60, 140) for taking out outwardly a torque transferred from the input system rotational member (10), and a torque transferring member (50, 150a,150b) interposed between the input system rotational member (10) and the output system rotational member (60, 140) for selectively making the two rotational members engage and disengage each other, wherein in order to perform securely torque transfer and cut off between the input and output systems and avoid any influence of an external force applied from the output system during torque transfer, the torque transferring member (50, 150a, 150b) is adapted to transfer torque in both forward and backward rotating directions while it engages the input system rotational member (10) and the output system rotational member (60, 140) and the output system rotational member (60, 140) is adapted to freely rotate only when the torque transferring member (50, 150a, 150b) is released from the output system rotational member (60, 140).

摘要： The magnetic attraction force of an electromagnetic coil in an electromagnetic clutch is increased in a limited installation space, thereby improving reliability of operation. The dimensions of a field core housing the electromagnetic coil and a rotor are optimized to increase the magnetic attraction force. The thicknesses of cylindrical portions on the inner-diameter side of the field core and the rotor have larger thicknesses than those of cylindrical portions on its outer-diameter side so that the sectional areas of both cylindrical portions will be equal to each other. Also, a rotation transmission device provided with an electromagnetic clutch is proposed which can avoid deterioration of its sealing property and damage to its bearing and avoid cost increase.

摘要： A rotation transmission device includes inner and outer rings, a two-way clutch mounted between the outer and inner rings, and an electromagnetic clutch mounted adjacent to the two-way clutch. The electromagnetic clutch includes a rotor guide pressed onto the outer ring at its open end and a rotor pressed into the rotor guide. The rotor guide is made of a magnetic material having the same or substantially the same coefficient of linear expansion as the material of the rotor. Thus, even when the rotor guide and the rotor are heated and expanded, the interference between the rotor and the rotor guide remains substantially constant. Therefore, the rotor and the rotor guide can be reliably coupled together with a simple structure and at a low cost.

摘要： A rotation transmission device is provided which is used to selectively transmit power. The aim is to stabilize the frictional torque when the rotor of an electromagnet absorbs an armature. A retainer is mounted between an inner member and an outer member, and is formed with a plurality of pockets, and engaging elements are mounted in the pockets. An armature is mounted so as to be nonrotatable but axially movable relative to the retainer, and a rotor is mounted to the inner member or the outer member so as to axially oppose the armature. An electromagnet attracts the armature to the rotor, thereby changing the phase of the retainer to bring the engaging elements into engagement with the outer periphery of the inner member and the inner periphery of the outer member, and thereby transmitting a turning torque between the inner member and the outer member. When the armature is attracted to the rotor, the large-diameter portion of the armature is attracted to the rotor.
