Description
Technical field
The present invention relates to a kind of lubrication system, more particularly, to a kind of novel bearing lubricating structure.
Background technology
Bearing is the key component in Helicopter Transmission System, and the quality of its performance directly influences Helicopter Transmission System
Service life and reliability, and the lubricating system of excellent in design is to improve bearing service life and the most important of reliability to arrange
Apply.Main reducing gear input rotating speed is high, power is big, high to the lubricating requirement of bearing, therefore designs a kind of excellent bearing profit
Slipped Clove Hitch structure is imperative.At present, the bearing lubrication mode lubricated under the ring mainly used.The main of ring lower bearing lubricating system lacks
Putting is：Under the conditions of high-speed overload, bearing lubrication effect is bad, and when bearing size is larger, bearing heating amount is bigger, serious shadow
The life-span of bearing is rung.
Lubricating method is to utilize centrifugal force under ring, by lubricating oil via many radial holes being opened on rotary shaft inner chamber（Such as
Four annular oilhole A, B, C, D shown in accompanying drawing 1）And raceway face is sprayed to, a part for lubricating oil makees axially stream along below inner ring
Purpose that is dynamic and reaching cooling inner ring.Lubricating oil into raceway is divided into left and right two passes and flowed outwardly, and heat is taken away.
The content of the invention
The technical problem to be solved in the present invention is to overcome lubrication system lubricant effect under existing bearer ring bad not
Foot, there is provided lubricated under a kind of existing ring, there is the binary channels bearing lubrication structure lubricated on ring again, two-way lubrication system is independently transported
OK, it does not interfere with each other, solves the big technical problem of bearing heating amount under the conditions of high-speed overload well.
The above-mentioned purpose of the present invention is achieved by the following technical programs：
A kind of novel bearing lubricating structure is provided, the bearing includes the roller bearing and ball bearing of concentric installation, axle
Hold and be installed in hollow rotary shaft, casing, end cap and the axle between end cap and bearing are installed from outside to inside outside bearing
Hold bushing；The lubrication system includes lubrication system under ring, under the ring lubrication system include being arranged at the A of rotary shaft inwall,
B, C, D tetra- encloses lubrication hole；
Oil Guide set is provided between the roller bearing and ball bearing, the Oil Guide set is to be provided with the pipe that Oil Guide covers oilhole
Part, Oil Guide set are compressed by roller bearing and ball bearing, and being provided with two small oilholes on an Oil Guide set oilhole side will can slide respectively
Oil is passed through roller bearing and ball bearing；Oil circuit is communicated with by the casing, end cap, bearing insert and Oil Guide set, lubricating oil passes through
Oil circuit is delivered to bearing.
Preferably, casing oilhole is provided with the casing；End cap oil groove is set on the end cap, set under end cap oil groove
There is end cap oilhole；Some kidney slots are provided with bearing insert；The Oil Guide, which is put, is provided with Oil Guide set oil groove, and the Oil Guide covers oilhole
Open in Oil Guide set oil groove, the quantity of Oil Guide set oilhole is several；The casing oilhole, end cap oil groove, end cap oilhole, bearing
Bushing kidney slot, Oil Guide set oil groove, Oil Guide set oilhole and the small oilhole on Oil Guide set oilhole side are sequentially communicated to form oil circuit.
In assembling process, if being both provided with the hole of a logical lubricating oil on all parts, to form oil circuit, on each part
Hole must all align, in this case, because each part is separately fabricated, and the fastening between each part need to be ensured
Property, so it is difficult to the hole on all parts is alignd.Therefore, end cap oil groove, some kidney slots, Oil Guide set oil groove and some are set
Oil Guide covers oilhole, the lubricating oil injected from casing oilhole, first flows into end cap oil groove, then flows into oilhole through end cap oil groove, similarly sets
Some kidney slots are put, ensure that lubricating oil smoothly flows therein Oil Guide set oil groove, enter back into Oil Guide set oilhole.And in Oil Guide set oilhole
It is difficult alignment bearings that oil, which will smoothly enter bearing to be also, therefore sets some Oil Guide set oilholes to ensure that lubricating oil can flow into bearing and enter
Row lubrication.
It is further preferable that the quantity of the bearing insert kidney slot is 6.
It is further preferable that the quantity of the Oil Guide set oilhole is 6.
It is further preferable that the rotary shaft inner chamber sets the oil-bearing structure of the oriented rotary shaft outer surface depressions.It is described
Rotary shaft inner chamber sets the oil-bearing structure of the oriented rotary shaft outer surface depressions, plays a part of temporary transient oil storage, is easy to lubricating oil
Into four row annular oilhole A, B, C, D in rotary shaft.
The oil-bearing structure is " recessed " shape structure.
The invention has the advantages that：
A kind of novel bearing lubricating structure of the present invention, the lubricating structure include lubricating under lubrication and ring on ring, institute
Lubrication mainly makes lubricating oil be ejected on rolling element by the oil circuit of casing and end cap on the ring stated, so as to lubricate bearing；Under ring
Lubrication mainly by " recessed " shape structure oil storage of rotary shaft inner chamber, then passes through four row annular oil in rotary shaft using centrifugal force
Hole makes lubricating oil enter bearing inner ring and retainer progress bearing lubrication.Moistened using the binary channels bearing lubricated on lubrication under ring and ring
Sliding mode, bearing lubrication effect is preferable, solves the big technical problem of bearing heating amount under the conditions of high-speed overload well.Enter one
Step ground, to make lubrication system on the ring meet practical set demand, is provided with casing oilhole on the casing；On the end cap
End cap oil groove is set, and end cap oil groove is arranged with end cap oilhole；Some kidney slots are provided with bearing insert；The Oil Guide is put out
There is Oil Guide to cover oil groove, the Oil Guide set oilhole covers oil groove bottom by Oil Guide；The casing oilhole, end cap oil groove, end cap oilhole,
Bearing insert kidney slot, Oil Guide set oil groove, Oil Guide set oilhole and the small oilhole on Oil Guide set oilhole side are sequentially communicated to form oil
Road, meet the demand of practice.
The present invention uses under ring the binary channels bearing lubrication mode that lubricates in lubrication and ring, structure is novel, lubricant effect compared with
Good, two-way lubricating system is not interfere with each other, independent operating, adds the reliability of bearing lubrication, while by increasing oil lubrication
Amount reduces the caloric value of bearing, improves bearing life.
