| When an armature plate is attracted to a rotor so that the turning force of the rotor is transmitted to the armature plate, the turning force of the armature plate is transmitted to a main shaft via a plate spring. An angle (hereinafter referred to as a slope angle) formed between the plate spring and the armature plate is set so as to be not smaller than 10° and not larger than 63°. Therefore, since the slope angle is larger than the slope angle (about 3°) of the general electromagnetic clutch, the torque increase effect increases about 5 percent as compared with the general electromagnetic clutch, and also an excessive pressing force of the plate spring does not develop. | ||||||

| An electromagnetic clutch includes a rotor, armature hub, armature, magnetic body and first permanent magnet, field core, excitation coil, and second permanent magnet. The rotor is rotatably disposed in the housing of a driven device. The armature hub is fixed to the rotating shaft of the driven device. The armature is disposed on the armature hub to be movable in an axial direction. The magnetic body is incorporated in the rotor. The first permanent magnet connects the armature to the rotor. The field core is attached to the housing and inserted in the rotor to be in noncontact with it. The excitation coil is disposed in the field core and excited, when cutting off power transmission, to cancel a magnetic force of the first permanent magnet, thus releasing the armature from the first permanent magnet. The second permanent magnet separates the armature from the rotor, when cutting off power transmission, to move the armature toward the armature hub. The first permanent magnet has a Curie temperature lower than the temperature of heat generated by the rotor upon slip rotation. | ||||||

| An electromagnetic clutch for separably coupling a drive source and a rotary shaft has a rotor to be disposed in the outside of the rotary shaft concentrically therewith. The rotor is rotated by a drive source and accommodates an electromagnetic coil. The electromagnetic clutch has an armature plate that is attracted toward the rotor by an electromagnetic force generated by the electromagnetic coil so as to adhere to the rotor. Furthermore, the electromagnetic clutch has a coupler for coupling the armature plate and the rotary shaft to each other. The coupler includes a center part to be coupled to the rotary shaft and an elastically-deformable outer part for coupling the center part to the armature plate, the outer part being extended from the center part and elastically deformed when the armature plate is attracted to the rotor. | ||||||

| An electromagnetic clutch reduces clutch operating noise at a low cost by utilizing elastic members which are suited to a spring force of a leaf spring. An approximate nonagonal leaf spring has an outer ring portion, attachment portions connected to a hub, and connecting portions. Under the outer ring portion, securing portions of an armature are disposed. First elastic members are disposed at intermediate points of the securing portions, and a second elastic member is disposed in a gap between the leaf spring and the hub along an axial direction. When actuating the electromagnetic clutch, the leaf spring compresses the second elastic member, and when stopping the electromagnetic clutch, the armature collides with the first elastic member so that an axial position of the armature is secured. | ||||||

| A radial ball bearing 14 of the three point contact type or four point contact type is used for the rolling bearing for a compressor pulley. The offset amount null, that is the axial distance between the center null of the radial load applied to the follower pulley 4 from the endless belt 11, and the center null of the radial ball bearing 14 is 40% or less of the diameter of the pitch circle. In addition, the radial clearance of the radial ball bearing 14 is 0.2% or less of the diameter of the pitch circle. With this construction, the durability of the rolling bearing to support the follower pulley 4 is secured while made compact. | ||||||

| In an electromagnetic clutch, a rotor, an armature and a stator housing including an electromagnetic coil are assembled to a center hub through a bearing member. Therefore, by assembling the center hub to an engine crank shaft, an assembling operation of the electromagnetic clutch to a vehicle is finished. In addition, a stator plate fixed to the stator housing is fixed to an engine through a bushing made of an elastic material. Therefore, a vibration displacement of the stator housing relative to the rotor, generated due to vibration of the engine, can be absorbed. | ||||||

| 116 | Armature for a selectively engageable and disengageable coupling | US10027095 | 2001-12-20 | US20020050436A1 | 2002-05-02 | Charles A. Boyer; Jeffrey C. Steiner |
| An armature for a selectively engageable and disengageable coupling and a method of making the armature are provided. The armature includes a substantially annular body that is disposed about a first axis. The body may be formed by stamping or fine-blanking. One side of the body is hardened through a nitriding process. A grinding wheel is then applied at an angle to the same side of the body along a diametrical line of the body extending perpendicular to the first axis. As a result, the body is configured so that the thickness of the body increases as the distance from the diametrical line increases. In particular, the thickness of the body varies along each cross-section taken along the line from a minimum thickness at the innermost portion of the cross-section to a maximum thickness at the outermost portion of the cross-section. The inventive armature reduces galling, and the resulting noise, that occur during burnishing of couplings incorporating the armature. | ||||||

| 118 | Electromagnetic coupling armature assembly with flux isolator springs | US700439 | 1991-05-15 | US5119915A | 1992-06-09 | Dennis J. Nelson |
| An armature assembly for an electromagnetic coupling includes an armature plate made of a material having low magnetic reluctance and also includes an output hub having angularly spaced and radially extending mounting arms for supporting the armature plate. The armature plate is connected to the mounting arms by angularly spaced leaf springs which couple the armature plate and the output hub for rotation in unison while allowing the armature plate to move axially relative to the mounting arms when the coupling is engaged and disengaged. The leaf springs are made of a material having high magnetic reluctance and are formed with tabs or fingers which are sandwiched between the armature plate and the mounting arms to create a flux barrier for magnetically isolating the armature plate from the mounting arms and the output hub. | ||||||

| An electrically powered drive apparatus comprises a first clutch plate secured to an output shaft and a second clutch plate mounted to a gear which is rotatably and slidably provided on the output shaft. The second clutch plate comprises a resilient transmission member and a magnetically-attracted contact member. The resilient transmission member is secured at a first portion to the gear and is adapted to resiliently deflect. The contact member is secured to a second portion of the resilient transmission member. The resilient transmission member has teeth into which pins extend in meshing engagement. When a clutch coil is energized, the contact member is attracted by the first clutch plate to thereby cause the pins to engage the teeth, thereby transmitting rotational force from the drive source to the gear. When the clutch coil is de-energized, the contact member is released to return to its home position with the aid of the resiliency of the resilient transmission member. | ||||||

| In an electromagnetic clutch, the movable clutch plate which acts as an armature is connected to a drive member by a spring plate having a plurality of deformable arms. The deformable arms are rigidly connected to the drive member at one end thereof while the opposite ends of the arms are connected to the clutch plate by rivets with the reduced armature shank portions of the rivets being located in elongated holes in the ends of the arms. The heads of the rivets are located in notches in the drive member to prevent relative rotation of the clutch plate relative to the drive member while permitting axial movement relative thereto. | ||||||
