Oil fuel tube is directly connected by oil filler point with bearing chamber in above-mentioned patent document, using oil fuel tube in bearing chamber
During oiling, it is not easy to control, so that lubricating grease can be caused to inject lubricating grease spillover that is excessive and occurring, to whole clutch
Cause to damage.
The content of the invention
A kind of above mentioned problem that the present invention exists for existing technology, there is provided electromagnetic clutch, the present invention to be solved
Technical problem be：The lubrication seborrhea for how effectively preventing the lubricating grease injection in electromagnetic clutch in shoe cream room excessive and occurring
Go out to damage clutch phenomenon.
The purpose of the present invention can be realized by following technical proposal：
A kind of electromagnetic clutch, the electromagnetic clutch includes thering is bearing chamber, the bearing chamber in housing, the housing
Bearing is inside provided with, the oil filler point along housing radial direction is offered on the housing, it is characterised in that be additionally provided with the bearing chamber outer
Spacer, is provided with the shoe cream room being connected with the Bearing inner in the outer separator, the outer surface of the outer separator is provided with and institute
The Oil Guide passage that oil filler point is connected is stated, the oil-feed of the connection Oil Guide passage and the shoe cream room is offered on the outer separator
Hole；The oil filler point and the fuel feed hole stagger setting.
Its operation principle is as follows：The agent structure of this electromagnetic clutch and electromagnetic clutch of the prior art substantially phase
Together, rotating shaft is connected with the technical program middle (center) bearing, the long-time of bearing runs at high speed, it is necessary to continual lubricating oil or profit
Consistent lubricant is lubricated, and housing is set on outer separator and bearing, and the shoe cream room in outer separator is used to store lubricating oil or lubrication
Fat, lubricating oil or lubricating grease can enter into it is lubricated in bearing, play a part of to reduce friction and wear and tear；In housing
On oil filler point at be also associated with oil nozzle, to shoe cream room inject lubricating oil or lubricating grease when, lubricating oil or lubricating grease are successively from oil
Shoe cream room is entered back into after mouth, oil filler point, Oil Guide passage and fuel feed hole, with oil nozzle in traditional clutch directly and shoe cream room
Connected structure is compared, and the inflow path of whole lubricating oil or lubricating grease is greatly prolonged in the technical program, can so be utilized
Adhesion is formed between the viscosity of grease, with Oil Guide vias inner walls more long, fill cup hydraulic is increased, this resistance adds oil storage
Internal pressure after lubricating oil or lubricating grease are had one's bosom filled with chamber, just can effectively prevent the entrance of lubricating oil or lubricating grease, so that effectively
Avoid because shoe cream room inside oil mass cannot be spied on, and the spillover excessively occurred to the grease injected in shoe cream room.
In above-mentioned electromagnetic clutch, the outer surface of the outer separator seals against with the madial wall of the housing, institute
It is the groove that is opened on the outer separator outer surface and groove is circumferentially disposed along the outer separator to state Oil Guide passage.So
Convenient processing and assembling, groove can just form the Oil Guide passage of closing with the madial wall of housing, so as to increase lubricating oil or lubrication
The circulation path of fat, pressure during increase oiling, by oil filler point to can fit can when injecting lubricating oil or lubricating grease in shoe cream room
And stop, it is prevented effectively from injection and excessively spillover occurs.
In above-mentioned electromagnetic clutch, the outer surface of the outer separator is brought into close contact to be formed with the madial wall of the housing
Static seal.Lubricating oil or lubricating grease in Oil Guide passage are so effectively prevented from Oil Guide passage both sides, between outer separator and housing
Gap in permeate outflow.
In above-mentioned electromagnetic clutch, the groove is located at the medium position on the outer separator width.So
Lubricating oil or lubricating grease can be rapidly filled with whole shoe cream room.
In above-mentioned electromagnetic clutch, the Oil Guide passage is annular in shape and around the outer separator one week, the oil filler point
Axis and the fuel feed hole axis perpendicular.Lubricating oil or lubricating grease reach fuel feed hole from oil filler point by Oil Guide passage

It is 0.2mm~0.6mm.Preferably, the width of Oil Guide passage is 7mm, the depth of Oil Guide passage is 0.4mm.Oil Guide passage
Depth and width are sufficiently small, and the need for should meeting lubricating oil and lubricating grease circulation, it is met again increases enough adhesions
It is required that.
In above-mentioned electromagnetic clutch, a diameter of 4mm~8mm of the fuel feed hole.Preferably, the diameter of fuel feed hole
It is 6mm.This size can control lubricating oil and lubricating grease to enter fashionable speed, reduce its impulsive force for overcoming adhesion, from
And increase fill cup hydraulic, prevent oiling transition.
In above-mentioned electromagnetic clutch, the quantity of the bearing is two, is had between the inner ring of the bearing and outer ring
Have a cavity, two relative sides of bearing are respectively provided with the opening of the connection cavity and the shoe cream room, two bearings it is another
Side is equipped with sealing ring.Ball roller is provided with cavity, the lubricating oil or lubricating grease in shoe cream room can be by openings smoothly
Enter into cavity to being lubricated between bearing inner race and outer ring.
In above-mentioned electromagnetic clutch, the outer peripheral face flush of the outer peripheral face of the housing and the bearing outer ring, institute
State side of the two sides of housing respectively with two bearing outer rings to lean, be additionally provided between two inner rings of the bearing
Inner spacing collar, the side of the two sides of the inner spacing collar respectively with two bearing inner races leans.Such periphery of inner spacing collar
The side of face, the madial wall of outer separator, the inner ring of two bearings and outer ring opposite side is collectively forming above-mentioned shoe cream room, stores up
Lubricating oil or lubricating grease in oil pocket smooth can be entered into two bearings, so as to ensure two lubricant effects of bearing.
In above-mentioned electromagnetic clutch, alternatively, the bearing can use a biserial deep-groove ball axle
Hold, outer separator is the annulus in the middle part of biserial deep groove ball bearing outer ring, common shape between outer ring, inner ring and two row deep-groove balls
Into above-mentioned shoe cream room, the biserial deep groove ball bearing outer ring center outer surface opens up Oil Guide groove, and is further opened with outer ring
The oilhole of connection Oil Guide groove and shoe cream room, so as to can also reach the object of the invention.
In above-mentioned electromagnetic clutch, used as the third scheme, the quantity of bearing is one, and outer separator is located at bearing
Side, the side adjacent with outer separator does not carry out end part seal on bearing, and opposite side is sealed, i.e., in outer separator
Shoe cream room is connected with Bearing inner；Outer separator side is leant with bearing, and opposite side is then sealed using seal, so
Also disclosure satisfy that demand.
Compared with prior art, the present invention in electromagnetic clutch inject lubricating oil or lubricating grease when, by set
Oil Guide passage greatly prolongs lubricating oil or the inflow path of lubrication, can so utilize the viscosity of grease logical in Oil Guide more long
