Abstract
An electromagnetic clutch used for controlling rotating speed and working manner of the electromagnetic clutch. External leading wires of a magnet yoke coil can be fractured from the root of a wire outlet when a friction type electromagnetic clutch transports a small torque or is in an accident, and therefore normal work of the electromagnetic clutch is influenced. The electromagnetic clutch comprises a magnet yoke coil (2), one end of the magnet yoke coil is connected with an active end of a coupling (1), and the other end of the magnet yoke coil is connected with an armature (4). The magnet yoke coil is connected with a terminal plate through external leading wires, a spring (3) is arranged between the magnet yoke coil and the armature, one side of the armature is provided with a friction plate (5), an internal tooth sleeve (6) is arranged outside the friction plate, and an external tooth shaft sleeve (7) of a driven end of the coupling is installed inside the friction plate. The electromagnetic clutch is used for machinery field.

technical field:
the utility model relates to a kind of magnetic clutch.
background technique:
magnetic clutch is widely used in various mechanical transmission, be used for controlling rotating speed and working method thereof, can be divided into tooth-like, pneumatic type, castellated and friction type etc., along with scientific and technological development, requirement to clutch is more and more high, only have the transmitting torque of clutch larger, speed is faster, inertia is less, could meet mechanical technique adjustment and high-precision processing, and for the magnetic clutch of friction type when transmitting less moment of torsion and contingency, yoke coil external lead wire just often occurs from wire outlet fracture of root phenomenon, thereby affected the normal operation of magnetic clutch.
summary of the invention:
the purpose of this utility model is to provide a kind of magnetic clutch, it is the problem that employing yoke coil external terminal plate and the mode that groove is set on friction plate overcome above-mentioned existence, coil lead is no longer ruptured, increased driving torque, realized the fast clutch of driving shaft and driven shaft.
above-mentioned purpose realizes by following technological scheme:
a kind of magnetic clutch, its composition comprises: the yoke coil, described yoke coil one end is connected with the coupling drive end, the described yoke coil the other end is connected with armature, described yoke coil is connected with terminal board by external connection, between described yoke coil and described armature, spring is housed, and described armature one side is equipped with friction plate, internal tooth casing is equipped with in the described friction plate outside, and coupling driven end externality shaft is equipped with in described friction plate inboard.
described magnetic clutch, described yoke coil external connection comprises circumscripted power line and external lead wire, be provided with insulating gum cover and insulation protective board on described circumscripted power line and external lead wire, the involute tooth type that the tooth section pressure angle of described friction plate is 30 degree.
described magnetic clutch, described friction plate is set to annular, and described Friction Disk Surface evenly is provided with one group of annular groove, the shallow slot of one group of wide 1.5mm of dark 0.5mm of crosscut on described annular groove.
beneficial effect:
1. the utility model connecting end daughter board on yoke coil external lead wire and circumscripted power line, solved at magnetic clutch and run well and the contingency that causes because of external environment makes the problem of yoke coil outer fuse from the wire outlet fracture of root, made to manufacture the electromagnetism electric installation process simplification of magnetic clutch.
2. the Friction Disk Surface that the utility model adopts is arranged to the annular ditch grooved and has been increased frictional force, is convenient to chip removal, has obtained larger moment of torsion.
3. the utility model friction plate adopts the involute profile of 30 degree, is a kind of ultrashort profile of tooth, has reduced radial dimension, has improved 4-6 times of Gear Surface Strengths, can obtain larger moment of torsion.
4. the utility model is provided with insulating gum cover and insulation protective board near the winding wire of wire outlet, has avoided coil to bend from root, has reduced wearing and tearing, has increased working life.
5. the utility model installation is simple, easy to maintenance, and easy operating is not easy to wear, is a rare magnetic clutch.
the accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is external connection end daughter board termination sectional drawings.
accompanying drawing 3 is accompanying drawing 1 friction plate schematic diagram.
accompanying drawing 4 is friction plate profile of tooth figure of accompanying drawing 1.
embodiment:
embodiment 1:
a kind of magnetic clutch, its composition comprises: yoke coil 2, described yoke coil one end is connected with coupling drive end 1, the described yoke coil the other end is connected 4 with armature, described yoke coil is connected with terminal board 9 by external connection, between described yoke coil and described armature, spring 3 is housed, and described armature one side is equipped with friction plate 5, internal tooth casing 6 is equipped with in the described friction plate outside, and driven end externality shaft 7 is equipped with in described friction plate inboard.
embodiment 2:
described magnetic clutch, described yoke coil external connection comprises circumscripted power line and external lead wire, be provided with insulating gum cover 10 and insulation protective board 8 on described circumscripted power line and external lead wire, the involute tooth type that the tooth section pressure angle of described friction plate is 30 degree.
embodiment 3:
described magnetic clutch, described friction plate is set to annular, and described Friction Disk Surface evenly is provided with one group of annular groove, the shallow slot of one group of wide 1.5mm of dark 0.5mm of crosscut on described annular groove.
magnetic clutch of the present utility model is by the spring force combination, by the friction carry-over moment being arranged, being realized throwing off by the electromagnetic force adhesive, it is work like this: the yoke coil electricity produces magnetic flux, the magnetic line of force forms closed-loop path through yoke and armature, and generation electromagnetic attracting force armature pressuring spring, make between friction plate to produce gap, realize the disengaging of magnetic clutch driven end and yoke coil; After the yoke coil blackout, magnetic flux disappears, and spring restores to the original state, and promotes magnet and moves the pressing friction sheet, and drive end and driven end are linked together by overall viewing range, realizes in conjunction with action.
