Description
Technical field
The invention belongs to the improvement technology of motor bearings, be specifically related to row's fat structure automatically of a kind of motor rolling bearing.
Background technology
Rolling bearing is that the sliding friction between axle and the axle bed of operating is become rolling friction, thus reduces friction loss
The mechanical organ of a kind of precision, the lubricating reliability of bearing and run operating temperature the service behaviour of bearing is affected very
Greatly.Rolling bearing generally uses and gets rid of fat dish row's fat structure and without row's fat structure at present.Get rid of fat dish row's fat structure to also exist and get rid of fat dish
Too big with grease frictional heat, in turn result in bearing operating temperatures the highest.Then cannot be in external force because of grease without row's fat structure
Being discharged to bearing under effect, in causing bearing chamber cavity, grease is too much, has thick one between bearing outer face and bearing end cover
Layer grease, causes bearing to dispel the heat, and bearing operating temperatures is the highest.These two kinds of structures all can cause bearing operating temperatures high,
The operational reliability of bearing is deteriorated；Bearing produces extra frictional dissipation, reduces the efficiency of motor, consumes substantial amounts of electricity
Can, and grease is both needed to manually discharge, and as being late for manually arranging fat, in will result in bearing chamber cavity, grease is too much,
Bearing friction increases further, and bearing temperature is further up, and artificial row's fat operation complexity, field device maintenance personnel work by force
Degree is big, is difficult to improve the automaticity of motor.
Summary of the invention
Present invention aim to address that existing rolling bearing gets rid of fat dish row's fat structure and without arranging the weak point of fat structure, from
And a kind of simple in construction is provided, perfect heat-dissipating, good airproof performance, the rolling bearing that working service automaticity is high arranges fat automatically
Structure.
For achieving the above object, the present invention adopts the following technical scheme that row's fat structure automatically of motor rolling bearing, including
Rotating shaft, rotating shaft is sequentially provided with bearing protecgulum, bearing and bearing bonnet, and described bearing is located in bearing block, in bearing protecgulum
Being arranged with in rotating shaft can be with the centrifugal drying alicyclic ring of axis of rotation, and on centrifugal drying alicyclic ring, both ends of the surface are provided with the rear centrifugal leaf towards bearing
Sheet, is provided with the gear fat weir plate of annular in bearing protecgulum, gear fat weir plate is arranged with bearing spacer, and described rear centrifugeblade is from gear fat weir
The front side of plate extands rearward in the annular distance of gear fat weir plate；The row's of being provided with fat hole on the bearing protecgulum of centrifugeblade radially side,
Row fat hole is positioned on front side of gear fat weir plate.
The row's fat chamber being positioned on front side of gear fat weir plate it is provided with between row fat hole and centrifugal drying alicyclic ring, at row fat hole in bearing protecgulum
Being provided with automatically row's fat assembly, described automatic row's fat assembly includes arranging fat cover plate, and described row's fat cover plate is covered in outside row fat hole also
Can close or the row's of opening fat hole.
Being covered with installing hole before described bearing and cover the installing plate of installing hole, installing plate and bearing protecgulum are that screw connects
Connecing, described row's fat hole is located on installing plate, and described automatic row's fat assembly also includes guide rod radially and spring, and installing plate is provided with leads
Bar jack, guide rod inserts in bearing protecgulum from guide rod jack, and row's fat cover plate is covered in the outside of installing plate, and guide rod outer end connects institute
The row's of stating fat cover plate, the inner that guide rod inserts in bearing protecgulum is provided with Spring Card, described spring housing be located at Spring Card and installing plate it
Between guide rod outer ring.
Described row's fat orifice ring arranges several around the uniform interval of guide rod.
Described rear centrifugeblade is fan annular, rear centrifugeblade twisted rotary shaft circumferential interval is uniform arrange several.
Being installed with circlip in rotating shaft, centrifugal drying alicyclic ring is fastened between circlip and bearing, centrifugal drying alicyclic ring bag
Include hot jacket torus in rotating shaft, the annular protrusion arranged around torus outer ring and the institute being located on annular protrusion rear end face
State rear centrifugeblade.
The front end face of described annular protrusion is provided with front centrifugeblade.
The annulus bore dia of gear fat weir plate is consistent with the pitch diameter at rolling element center in bearing.
Described rear centrifugeblade extands rearward to the medium position keeping off in the annular distance of fat weir plate from the front side of gear fat weir plate.
Automatically row's fat structure of motor rolling bearing of the present invention, has the advantages that
1, at bearing protecgulum, one gear fat weir plate is set near the position of bearing, keeps off inner ring diameter and the axis of rolling of fat weir plate
The pitch diameter holding rolling element center is consistent.Gear fat weir plate can make to store at bearing front end face the grease of fair amount, in rolling
In the lubrication interval again of dynamic bearing, grease can analyze enough oil lubrication bearings, improves bearing lubrication reliability,
Unnecessary grease can throw away bearing protecgulum with centrifugal drying alicyclic ring from row fat hole by gear fat weir plate, it is to avoid too much grease
With retainer friction, the frictional heat of less grease, reduce bearing running temperature.

Being scheduled in rotating shaft, centrifugal drying alicyclic ring is cast with the forward and backward centrifugeblade of multiple circumference uniform distribution, rear centrifugeblade is to gear fat weir plate
Annular distance in axially overlap sub-fraction, form centrifugal row's fat pump, when the unnecessary grease of bearing chamber is by gear fat weir plate
Time after arrival at centrifugeblade, because of the centrifugal action of blade, grease is thrown to arrange fat intracavity, and the lubrication to row's fat intracavity
Fat produces certain pressure, and the row's fat cover plate making grease push row's fat assembly automatically open is discharged to outside bearing protecgulum.
3. centrifugal drying alicyclic ring is equivalent to a centrifugal fan simultaneously, because it has certain pectinid ability, enhances bearing outer end
Air-flow whirling motion at face, strengthens the heat loss through convection ability of bearing, can effectively reduce the running temperature of bearing, improves the operation of bearing
Reliability；And its centrifugal fan wind energy power can be avoided by bearing protecgulum axle and run through the sealing dust of structure, moisture entrance bearing,
Improve the sealability of bearing, the safe and reliable operation of bearing can be ensured.
4. the row's fat cover plate automatically arranged on fat assembly closely cooperates with installing plate in normal operation, and coordinates face
The sealing function of toughness grease, good seal at this, enhance the sealing reliability of whole bearing arrangement.When row's fat intracavity
Grease abundant time, grease pushes cover plate under the effect of centrifugal drying alicyclic ring open and is discharged to outside bearing protecgulum, subsequently in pressure
Under the effect of the spring of contracting, cover plate automatically returns to normal operating conditions.During whole row's fat, it is not required to manually carry out any behaviour
Make, can realize automatically arranging fat, improve the automaticity of motor, facilitate the maintenance of field device maintenance personnel, reduce
Labor intensity.
