Abstract
The utility model discloses an electromagnetic clutch, which is characterized in that the end part of a gear sleeve is chucked with the retainer ring of an elastic restriction bearing. The inner part of the cavity of a magnetic yoke body contains a fixed coil by a bond coat, and the external gear of the gear sleeve is connected with a connection through at least two friction pairs which are composed of knee-pieces and plain pieces. The electromagnetic clutch can overcome or reduce the adhesion of oil films among the pieces and realize rapid combination or separation, and the coil is firmly enchased and does not fall off. The bearing can be permitted to have a little axial thermal expansion or movement in motion, and the electromagnetic clutch is sensitive, reliable and durable.
Description
The utility model relates to a kind of magnetic clutch, particularly is suitable for wet type multi-disc electromagnetic clutch.
At present the chip magnetic clutch is used in the machine driven system more, and it is under the active part working order, make secondary part and active part form in conjunction with or separate, reach purposes such as startup, braking, commutation.Wet type multi-disc electromagnetic clutch is to work in medium oil, and more general deficiency is: two rubbing surfaces of one fastness are smooth flat, produce bigger oil film cohesion therebetween, cause separation difficulty; The coil of inlaying in its two yokes body cavity is not firm, easily comes off; Its three pairs of bearings contingent a small amount of bearing deformation in service or play do not have guarantee on the structure, easily cause fault.
In order to address this problem, common way is that the ripple reed is set between outside friction disc, and CN-87208482 " the slip ring friction-type electromagnetic clutch is arranged " patent is just described to some extent, yet local deformation or breakage can take place because of discontinuity in friction plate, and can not solve fully described deficiency.
The purpose of this utility model is that a kind of improved wet type multi-disc electromagnetic clutch will be provided, and it can overcome or reduce oil film cohesion between sheet effectively, realizes reliably combination fast or separation.
The purpose of this utility model is achieved in that the be installed back-up ring of restriction bearing of tooth cover end, is loaded in the chamber of yoke body of bearing outer ring, contains fixed coil with adhesive layer, the external tooth of tooth cover with connect between with at least two fastnesses connections.
Fastness is provided with inside and outside friction plate.Interior friction plate can be with holes, opening, and circumferencial direction just is being (surplus) string waveform, radial direction and is being straight shape or arcuation, or is whole bowl-shape, the flexible knee-piece of ring; Also can be have hole, opening, be smooth flat or be shaped on spirality or several toroidal cavities, the plain film of ring.The outside friction disc that is complementary with it, corresponding or aforesaid plain film; Or aforesaid knee-piece.
The main component of adhesive layer is by weight percentage: epoxy resin 40～60%, curing agent 7～13%, plasticizer 7～13%, bulking agent 17～50%.
Flexible back-up ring is that the outer rim at open circles annular circle body has several equidirectional dogs, or is flat body folding pawl; Or be whole bowl-type.
The utility model employing elasticity knee-piece and plain film constitute fastness, can overcome or reduce oil film cohesion between sheet, realize combination fast or separation; Coil is inlayed firmly, and allows bearing that a spot of axial deformation or play are arranged.It is a kind of comparatively desirable wet type multi-disc electromagnetic clutch.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional drawing according to the wet type multi-disc electromagnetic clutch that the utility model proposes;
Fig. 2 is the sectional drawing that a kind of radial direction is the interior friction plate of straight shape;
Fig. 3 is the sectional drawing that another kind of radial direction is the interior friction plate of arcuation;
Fig. 4 is the sectional drawing that is the back-up ring of flat body folding pawl;
Fig. 5 is the sectional drawing that another embodiment of back-up ring is whole bowl-type;
Below in conjunction with details and the working condition of Fig. 1～5 detailed descriptions according to the concrete device that the utility model proposes.
This device is provided with the tooth cover 1 of inner splined hole, connects baffle plate 2 at the middle part with pin, and baffle plate is the steel plectane, and there is the magnetism resistent ring 3 of non-magnet_conductible material (as copper) at the middle part.Tooth cover end is shaped on axial trough, and with bearing (as selecting the E1000906 radial ball bearing for use) 4, the one sides baffle plate that reclines, behind the opposite side pad plain washer, back-up ring 5 is installed in said axial trough.Back-up ring shown in Fig. 4～5, select for use elastic metallic materials such as 65Mn, high-quality high carbon steel to make, circle body is the open circles annular, outward edge has uniform equidirectional dog more than three or three, make flat body folding pawl 5A shape or be whole bowl-type 5B, dog withstands the bearing side by plain washer, can ensure that bearing is in service, allow a spot of axial heat rise the distortion or play.Be loaded in the chamber of yoke body 6 of bearing outer ring, contain fixed coils 8 with adhesive layer 7.The main component of adhesive layer according to weight percentage is: epoxy resin 40～60%, curing agent (as benzene dimethylamine) 7～13%, plasticizer (as dibutyl phthalate (DBP)) 7～13%, bulking agent (as silicon powder) 17～50%, normal temperature is mixed cast thoroughly.Leave suitable working gas gap between adhesive layer exposed surface and baffle plate.Power supply is given coil by wire board 9 feeds.Connect with the fastness more than 2 or 2 between the external tooth of tooth cover and the connection 12, form by a curved rubbing surface and a planar friction face during fastness free state.This structure has two embodiments.In the illustrated scheme, select for use elastic metallic materials such as 65Mn, high-quality high carbon steel to make (knee-piece) interior friction plate 10, its circumferencial direction just is being (surplus) string waveform, radial direction is straight shape 10a or is arcuation 10b, be provided with several long arc shape holes with the corresponding position of magnetism resistent ring, and have at least three slotted holes to be shaped on the opening that is communicated with periphery, also be shaped on the internal tooth shifter collar.Shape as for interior friction knee-piece can also be whole bowl-type, flat bending shape or other similar shape (all not expressions among the figure); (plain film) outside friction disc 11 that is complementary with it should have same slotted hole, opening, and the opening of engagement connection, and the rubbing surface of both sides is a smooth flat, or is shaped on groove (also claiming oil groove) again, distributes twist or several rings.Inside and outside friction plate cross arrangement, outermost are interior friction plates.Another program of fastness is the interior friction plate of plain film shape; The outside friction disc of coupling knee-piece shape.It should be noted second scheme important be sheet deformationization.Moving armature 13 is also being meshed and the limited ring 14 that is being installed in tooth cover the other end.
Working condition is that such feed is in coil, the closed magnetic circuit that formation is made up of yoke body, baffle plate, friction plate, armature, under magnetic force, inhale moving armature, the pressing friction sheet, being multiple spot or face when knee-piece is stressed contacts with plain film, by the effect of its frictional force, the tooth cover connects to connect realizes transmitting torque.Stop feed magnetic force and disappear, knee-piece is according to the elastic return free state, and integral body flicks plain film (contain promote armature recline limited ring), and device separates, and stops transmitting torque.Experiment shows: oil film cohesion between sheet be can overcome or reduce, combination fast or separation realized, and the combination property that improves device.
