Description
The utility model is to belong to Clutch Technology, specifically is meant to adopt control electromagnetic field intensity, direction to obtain to start a kind of Clutch Technology with braking function.
Existing magnetic clutch startup separates with braking function, and the suction iron and the line shaft that have field coil rotate synchronously, and friction disk remains static, and keep to coil electricity, must adopt the brush form, and complex structure assembles difficulty like this; The magnetic clutch that has adopts the multilayer friction plate overlapping, and the garden connects with spline and axle sleeve in the friction plate, and cost increases, and easy to wear, reliability is relatively poor.Existing in addition magnetic clutch is often used for particular device, is difficult to exchange general.
The purpose of this utility model is will provide a kind of can start, again the electric clutch-brake that can brake.
The utility model has boot disk (1), inhales iron pan (2) altogether, brake disc (3), and transmission shaft (4) is formed.Inhaling iron pan (2) altogether is positioned between boot disk (1) and the brake disc (3), starter cup (6) is tightened fixing with location connecting plate (7) with screw (25), between location connecting plate (7) and starting friction sheet (9) and brake strip (15) and location nest plate (16), be placed with spring sheet (8), six uniform apertures of symmetry (26) are arranged above the spring sheet of garden sheet metal (8), three screws (25) are fastened on location connecting plate (7) and the brake strip (15), and three screws (25) are fastened on starting friction sheet (9) and the location nest plate (16) in addition.Starter cup (6) and the interior garden of connecting plate (7), location are embedded with a sleeve (5) and are enclosed within on the transmission shaft (4), gearing friction sheet (11) and location nest plate (16) are enclosed within transmission shaft (4) and go up with key (20) binding, inhale iron hoop (13) biend altogether and respectively open a groove, inlay starting coil (12) and restraining coil (14) in the groove, inhale the outer garden of iron hoop (13) altogether fixing frame (21) is housed, inhale the interior garden of iron hoop (13) altogether two bearings (19) are housed, it is fixing with screw (18) that trim ring (17) covers location nest plate (16).Starter cup (6), location connecting plate (7), spring sheet (8) and starting friction sheet (9) form an integral body.When driven by motor starter cup (6) rotated, starting friction sheet (9) also rotated thereupon, but does not have power transmission to give transmission shaft (4), i.e. boot disk (1) idle running.Inhaling iron pan (2) altogether is by gearing friction sheet (11), inhales iron hoop (13) altogether, starting coil (12), and restraining coil (14), bearing (19), fixing frame (21) constitutes.Control relay is switched on to starting coil (12), starting coil (12) produces the magnetic line of force makes it inhale iron hoop (13) magnetization, the magnetic line of force passes the suction of gearing friction sheet (11) generation to starting friction sheet (9), under the action of a magnetic field, when the suction of starting friction sheet (9) is enough to overcome spring sheet (8) to its pulling force, starting friction sheet (9) and gearing friction sheet (11) adhesive are one, and gearing friction sheet (11) rotates with starting friction sheet (9).Because gearing friction sheet (11) links with key cover form with transmission shaft (4), so the running torque of boot disk (1) can be transferred to transmission shaft (4) by gearing friction sheet (11), promptly drives the equipment work of required drive.After starting coil (12) outage, magnetic field suction disappears, starting friction sheet (9) resets under the tension of spring sheet (8), starting friction sheet (9) is thrown off with gearing friction sheet (11), boot disk (1) idle running, the transmission shaft (4) that has gearing friction sheet (11) to drive slowly stops operating under effect of inertia, and promptly equipment quits work.Brake disc (3) is by brake strip (15), and spring sheet (8) and location nest plate (16) constitute.Brake strip (15) is by spring sheet (8) and location nest plate (16) binding, identical in its mode of connection and the boot disk (1).Transmission shaft (4) afterbody trim ring (17) covers location nest plate (16) and fixing with screw (18), in case brake disc (3) comes off.After starting coil (12) outage, unpowered the applying of transmission shaft (4), under effect of inertia, transmission shaft (4) still can rotate certain hour.After restraining coil (14) energising, make common suction iron hoop (13) magnetization, produced the suction to brake strip (15) again, brake strip (15) overcomes spring sheet (8) and inhales iron hoop (13) adhesive together after to its pulling force.Because it is fixing with fixing frame (21) to inhale iron hoop (13) altogether, brake strip (15) is inhaled friction-produced moment on iron hoop (13) end face together, stops transmission shaft (4) to rotate, thereby obtains braking effect, and promptly equipment can quit work immediately.After transmission shaft (4) braking, inhale iron hoop (13) altogether and be attracting state with brake strip (15).For making it be free state, a time delay relay can be set, in the control needed time, cut off the electric current of restraining coil (14) automatically, common suction iron hoop (13) and brake strip (15) are thrown off.
The utility model is simple in structure, the reliability height, and easy to assembly, cost is low.

Be embedded with the friction material sheet (10) that increases moment on the end face of the gearing friction sheet (11) among the utility model embodiment and on restraining coil (14) surface.Transmission shaft (4) is the line shaft on the required drive equipment.Sleeve (5), the internal diameter size of gearing friction sheet (11) and location nest plate (16) can be changed according to the line shaft size of equipment.The utility model is enclosed within on the transmission shaft (4) of equipment, fixing frame (21) is being inhaled iron pan (2) altogether with screw-driving, then that support (22) is fixing with transmission axle bed (23) on one side, on one side fixing with fixing frame (21), its effect is not rotated common suction iron pan (2).
The utility model is specially adapted to textile manufacturing machine, it can with the supporting use of monitoring device, when finding broken yarn line or abnormality, monitoring device sends signal, electric clutch-brake is braked immediately, equipment quits work automatically.Pending fault is got rid of, and can start to work on.
