Abstract
The utility model discloses an oil throwing disk for an opening bearing. The oil throwing disk comprises a disk body, wherein a fixed surface which is matched with the inner ring of the opening bearing is arranged on the disk body; the disk body comprises an oil baffle outer spigot surface which is matched with an inner spigot of an outer cover of the opening bearing, and an oil throwing slope which is adhered to the oil baffle outer spigot surface, wherein the fixed surface is arranged on the oil throwing slope. The oil throwing disk for the opening bearing is reasonable and simple in structure, and can throw oil and baffle oil, so that the bearing can operate well in a best required oil state, and the designed longest service life of a motor can be achieved; heat resistance, corrosion resistance and anti-aging performance are high; the oil throwing disk for the opening bearing is not deformed at the temperature of 150 DEG C; long-time variable-load operating conditions of a diesel engine are adapted.
Description
Technical field
The utility model belongs to the motor bearings technical field, is specifically related to the disc that a kind of opening bearing is used.
Background technique
General disc is sleeved on electric machine main shaft, its card is disc, can reach the effect of sealing at the upper installation of shaft element (as the bearing) disc of high speed motion, its sealing principle is centrifugal seal, when the axle high speed rotating, disc is also high speed rotating, by the effect of centrifugal force, liquid medium is radially thrown away, stop liquid to enter and sew gap, thereby reach the purpose of sealing.
The disc structure of using on existing opening bearing, make its oil deflector more suitable, because practical structures has only played oil-blocking action, as shown in Figure 1 in fact.Its shortcoming is that grease unnecessary on bearing can't get rid of, as everyone knows, the oil quantity that bearing is suitable is inner chamber 2/3, but refuel, is with artificial intuition operation, the general operation personnel think and add a bit well, but bearing grease too much can cause motor bearings overheated and burn out a bearing.The real current situation middle (center) bearing burn out account for that motor burns out more than 50%, wherein bearing grease too much causes bearing heating to burn out accounts for thumping majority.
Summary of the invention
For the existing above-mentioned technical problem of prior art, the disc that the utility model provides a kind of opening bearing to use, by the disc Structure Improvement Design, make disc can accomplish that gear oil can get rid of grease unnecessary in bearing again.
The disc that a kind of opening bearing is used, comprise disk body, and described disk body is provided with the stationary plane coordinated with the opening bearing inner race, and described disk body comprises:
The gear oil outer stopper face coordinated with opening bearing end cover inner stopper;
Oily domatic with getting rid of of the oily outer stopper face laminating of gear;
Described stationary plane be located at get rid of oil domatic on.
It is described that to get rid of oil domatic for circular cone shape.
The total thickness of described disk body and stationary plane is 15mm.
The thickness of the oily outer stopper face of described gear is 2mm.
The thickness of described stationary plane is 4mm.
Described get rid of oil domatic thickness be 9mm.
Described get rid of oil the domatic gradient be 35 °.
In order to reduce production costs, the mechanical property of disc is provided, further: the disc material adopts engineering plastics.
The utlity model has following useful technique effect:
(1) reasonable in design is simple, can get rid of oil and can keep off oil again, makes bearing can under the required grease state of the best, well go fortune, reaches the highest working life of design of electrical motor;
(2) heat-resisting, corrosion-resistant, aging quality resistance is good, indeformable at 150 ℃ of temperature, adapts to the long-time varying duty Operation Conditions of diesel engine;
(3) bent axle of engineering plastics disc and motion and bearing fit, have the characteristics of obstruct and absorption noise, lower than the noise of metal disc contact movement, is conducive to reduce the total noise of centrifuge of motor.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing opening bearing with disc.
The structural representation that Fig. 2 is the utility model disc.
Fig. 3 is the sectional view of Fig. 2 along AA ' direction.
Embodiment
In order more specifically to describe the utility model, below in conjunction with the drawings and the specific embodiments, the technical solution of the utility model is elaborated.
As shown in Figures 2 and 3, the disc that a kind of opening bearing is used, comprise disk body, and disk body is provided with stationary plane 3, and disk body comprises the oily outer stopper face 1 of gear and gets rid of oil domatic 2; Wherein:
Keep off oily outer stopper face 1 and match with opening bearing end cover inner stopper, its thickness is as long as require small size on the basis of proof strength; In present embodiment, the thickness of the oily outer stopper face 1 of gear is 2mm.
Get rid of oil domatic 2 and fit with the oily outer stopper face 1 of gear, it is circular cone shape, and the domatic gradient is 35 °; In present embodiment, get rid of oil domatic 2 and oily outer stopper face 1 the being integral design of gear, the thickness that gets rid of oil domatic 2 is 9mm.
The thickness of whole disc is 15mm, and the whole engineering plastics that adopt are made.
Like this, when motor rotation, if there is unnecessary grease in bearing cavity, can directly from getting rid of oil domatic 2, throw out, because the face of being sealed and matched is little of running power is extruded outside oil thrower ring, discharge from the enclosing cover oil drainage hole again; Can get rid of oil and can keep off oil again, make bearing can under the required grease state of the best, well go fortune, reach the highest working life of design of electrical motor.
Claims (8)
