摘要： A spindle unit includes a swing mechanism fixed to a fixed frame, a support member swingably supported by the swing mechanism, a spindle main body and an electromagnetic brake supported by the support member. The spindle main body rotates integrally with a bobbin around which a yarn is wound. The electromagnetic brake applies a resistance to the rotating spindle main body. The swing mechanism includes a fixed attachment member fixed to the fixed frame, a swing shaft supported by the fixed attachment member, a spring, and a sensor. The spring applies a spring force to the support member in a direction opposite to a direction in which the support member swings by the tension of the yarn. The sensor detects the tilt amount of the support member when the support member swings.

摘要： An electromagnetic clutch includes a field core including a coil storage groove, and a rotor including a core storage groove. The coil storage groove is formed by an inner cylindrical portion, an outer cylindrical portion, and a bottom portion. The bottom portion of the field core wholly projects to the outside of the core storage groove. The outer peripheral surface of the inner cylindrical portion and the inner peripheral surface of the outer cylindrical portion include a first transition surface and a second transition surface, respectively, on the bottom portion side. Each of the first transition surface and the second transition surface includes a tilting surface that gradually narrows the groove width of the coil storage groove along with an increase in a distance from the side of the opening of the coil storage groove.

摘要： An electromagnetic connecting device includes a flange of a hub, an armature supported by the flange via a leaf spring, a rotor accommodating an electromagnetic coil, and an anti-vibration member. When an electric current is supplied to the electromagnetic coil, the armature moves in the axial direction of the hub against the spring force of the leaf spring, and is attracted to the rotor. The leaf spring includes a moving portion that moves in the axial direction together with the movement of the armature. The anti-vibration member is fixed to the moving portion of the leaf spring. The anti-vibration member includes a stopper that comes in contact with the flange, and a damper that comes in contact with the armature. With this configuration, an electromagnetic connecting device capable of reducing an impact sound both when the armature is attracted and released can be manufactured at a low manufacturing cost.

摘要： An electromagnetic clutch includes a rotation transmission member supported by an input shaft portion via a bearing. The rotation transmission member includes a movement regulating portion having abutment portions that abut against the bearing. The clutch further includes first and second spring members that bias an armature toward a braking member, and a connecting member overlaid on the movement regulating portion. The connecting member has first holes at portions facing the abutment portions, and second holes at portions facing regions between the abutment portions. One-end portions of the first and second spring members are attached to the armature. First fixing members inserted into the first holes fix the other-end portions of the first spring members to the connecting member. Second fixing members inserted into the second holes fix the other-end portions of the second spring members to the connecting member and fix the connecting member to the movement regulating portion.

摘要： An electromagnetic clutch device includes an armature, a rotor, an electromagnet, and a silencing member. The armature is supported by a driving member so that the armature is movable in the axial direction and rotate integrally with the driving member. The rotor is arranged coaxially with the armature, rotate with respect to the armature and rotate integrally with an output member. The electromagnet presses the armature and the rotor against each other based on an electromagnetic attraction force generated when current is supplied through the electromagnet to be coupled with each other in the torque transmittable manner. The silencing member is provided on an outer circumferential portion of the armature to attenuate noise generated by the vibration of the armature in a state where the silencing member is out of contact with any member other than the armature.

摘要： An electromagnetic connection device includes an armature (4), a rotor (3), an electromagnetic coil (14), and a spring member (24) that biases the armature (4) in a direction in which the armature (4) is separated from the rotor (3). The electromagnetic connection device includes a damping member (25) mounted on the armature (4) so as to face the rotor (3). The armature (4) includes a flat portion (22) and a tubular portion (8). The damping member (25) includes a damper cover (26) including an abutment portion along the flat portion (22) and an engaging portion along the tubular portion (8), and an elastic member (27) sandwiched between the abutment portion and the flat portion (22). The damper cover (26) is put on the armature (4) from the side of the rotor (3) and movably held on the tubular portion (8). The flat portion (22) includes a concave portion (35) configured to store the abutment portion of the damper cover (26). There is provided an electromagnetic connection device capable of obtaining a high damping effect and raising the productivity while preventing the elastic member from being exposed to a friction surface.

摘要： An electromagnetic clutch includes an armature to be attracted to a rotor, an armature hub formed on one end portion of a rotating shaft, and a leaf spring which connects the armature to the armature hub and biases the armature away from the rotor. The leaf spring includes a base fixed to the armature hub, a stopper connected to the base, and a connecting piece surrounding the stopper by projecting outside from the base, and fixed to the armature. A through hole into which a rivet for fixing the base to the armature hub is inserted is formed in the base. A low-strength portion having strength lower than that in the periphery of the through hole is formed in a boundary portion between the base and a connecting portion.
