Abstract

The utility model discloses an electromagnetic clutch, comprising a circumpolar component. The circumpolar component is connected with a friction disc through a bearing, and the circumpolar component and the friction disc form a friction disc component. The running face of the friction disc is relative to a sucking iron disc, and the sucking iron disc and a spring piece form a sucking iron disc component. The utility model has the advantages of reasonable structure, compactness, high reliability, long service life and no fire hazard.

Description

Electromagnetic clutch

The utility model relates to clutch, the break in engineering element or the parts, is a kind of magneto drive clutch, furtherly, be a kind of band be contained in electromagnet in the clutch, and band can axially movable rubbing surface clutch; Also can say so a kind of part or parts of break are a kind of actuating mechanisms that is configured in the break or is used for break on the break, furtherly, be a kind of by electric power or magnetic means effect, be suitable for break that element is drawn close.

The various model magnetic clutchs and the break of domestic present production and use, all adopt compositions such as ripple spring sheet, brush, electricity ring and chuck, in actual applications, because structure owes rationally, have that to produce easily that spark, fire hidden danger difficultly remove, adhesive is thrown off unreliable, have a strong impact on quality of product and even damage mechanism, rate of fault height, maintenance are frequent, working life drawback such as weak point.

The purpose of this utility model provides the magnetic clutch of a kind of fire rational in infrastructure, no, sensitive reliable, long service life.

Technical solution of the present utility model is: a kind of magnetic clutch, comprise the circumpolar assembly, and the circumpolar assembly links by bearing and friction disk, and circumpolar assembly, friction disk constitute the friction disk assembly; The working surface of friction disk is relative with suction iron pan working surface, inhales iron pan and spring sheet and constitutes suction iron pan assembly.

Friction disk in the utility model is linked by key and axle, inhales iron pan and also is sleeved on the axle.Certainly also can be on manufactured good tape spool not, but connect by the user.

A circumpolar is arranged in the circumpolar assembly of the present utility model, and the relative one side with friction disk of circumpolar is embedded with electromagnetic coil, and electromagnetic coil has lead to be connected with circumpolar outward.Certainly, the circumpolar assembly also can adopt other suitable structural types.

Electromagnetic coil in the utility model is solid on circumpolar by epoxy resin glue.Certainly, also can adopt other suitable Connecting format.

Suction iron pan in the utility model is connected with drive wheel with screw by spring sheet.Certainly drive wheel also can be the same with axle, connected by the user.

Have waist shape or the interrupted annular hole slot that penetrates both ends of the surface on friction disk in the utility model, the suction iron pan working surface.Certainly, also can have the hole slot of other suitable shapes.

The nitride layer that one side in friction disk in the utility model, the suction iron pan both ends of the surface or two faces have 0.03-0.8.Certainly, also can replace other suitable structural types.

Drive wheel in the utility model is a belt pulley, and belt pulley is contained on one or the one group of bearing, and bearing is contained on the bearing housing that is sleeved on the axle.Certainly, drive wheel also can adopt other drive wheels, correspondingly, also can do suitable variation on the structure.

Suction iron pan in the utility model, friction disk, circumpolar adopt electrical pure iron or 10 ^#-20 ^#Steel is done.Certainly, also can adopt other suitable materials.

In the drive wheel both sides suction iron pan is housed all in the utility model, it is relative with a friction disk respectively that each inhales iron pan.Certainly, also can only inhale iron pan at drive wheel one side dress.

The utility model has the advantages that: removed brush that existing magnetic clutch or break have usually, electricity ring etc., do not produced electrical spark, thereby eradicated fire hidden danger.Simple for structure rationally do not have easily damaged parts substantially, and rate of fault is low, and amount of maintenance is little, long service life.Adhesive is thrown off reliably, is active in one's movements, and the moment transmission is stable, helps improving mechanical property and quality of product.Applicability is good, can be widely used in the occasion that clutch and break need be set.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a kind of magnetic clutch structural representation of the present utility model.

A kind of friction disk face structure schematic representation of Fig. 2 for being adopted in the utility model.

A kind of suction iron pan face structure schematic representation of Fig. 3 for being adopted in the utility model.

Fig. 1 has described an embodiment of the present utility model.A circumpolar assembly 7 joins together by bearing 1 with friction disk 8, and forms an individual components with end cap 2, fixed plate 4, inhales iron pan 17 and forms another parts with spring sheet 18.Inhale the end face that three socket head screws 19 of iron pan 17 usefulness, spring washer 20 are fixed in belt pulley 21, friction disk 8 and axle 12 rotations synchronously, the fixed plate 4 that circumpolar assembly 7 is housed is fixed by machinery mount.End cap 2 is fixed on the circumpolar assembly 7 by screw 22, and axle 12 1 ends are equipped with axle sleeve 23, baffle plate 24 and screw 25, and end cap 2 is fixing with circumpolar assembly 7 by screw 3 with fixed plate 4.Circumpolar assembly 7 comprises circumpolar 30, be embedded with annular magnet coil 27 on the circumpolar 30, electromagnetic coil 27 is solid on circumpolar 30 by epoxy resin 29 glue, is connected on the electromagnetic coil 27 and the outside lead 28 that joins, and lead 28 is fixed on the fixed plate 4 by tension disc 6 and screw 5.Belt pulley 21 is sleeved on the axle 12 by bearing 15 and bearing housing 11.Inhale iron pan 17 and axle 12 and bearing housing 11,15 on bearing back-up ring 9 and adjusting strip 10 also are housed.The other end of axle 12 is equipped with spacer 13.

Fig. 2 has described a kind of structure of friction disk.Have waist shape (or the interrupted annular) hole slot that penetrates two end face on the friction disk working surface.

Fig. 3 has described a kind of structure of inhaling iron pan.Inhale and also have waist shape (or the interrupted annular) hole slot that penetrates two end face on the iron pan working surface.Certainly, also be furnished with screw that usefulness is installed etc. on its working surface.

When the need clutch is worked, can connect the direct current safety power supply, can produce magnetic field by electromagnetic coil; the electromagnetism positive pressure is repeatedly passed friction disk 8 and is inhaled iron pan 17; to inhale iron pan 17 and inhale to friction disk 8 rapidly, belt pulley 21 rotates synchronously with axle 12, finishes transmission of torque; and output torque can guarantee that long-term stability does not reduce; in case outage, magnetic field disappears, and spring sheet 18 resets rapidly; the suction 17 disengagement times of iron pan are not more than 0.05 second, can guarantee that mechanically activated or inertial stopping distance is no more than certain limit.
