Description
Technical field:
The present invention relates to technical field of bearings, and in particular to the oily leaf sliding bearing of one kind six.
Background technique:
There is the application of sliding bearing in a plurality of types of mechanical equipments at present, bearing performance is joined during equipment operation
Several (such as bearing minimum oil film thickness, bearing film maximum temperature), vibration parameters (such as mechanical equipment cabinet vibration acceleration,
Axle center trail displacement etc.) there is stringent index request.The sliding bearing is suitable for multi-state and runs or persistently by outside
The geared machine equipment that alternating load influences, the Impact direction of sliding bearing can change with operating condition or the period becomes
Change, therefore used sliding bearing needs stronger adaptability.
Currently used sliding bearing structure form includes circular journal bearing, elliptic bearing, dislocation bearing, three oil film wedges (three oily leaves)
Bearing, four oily rachises hold and tilting-pad bearing；Above-mentioned first three bearing generally uses two oily impeller structures, changes to Impact direction
Adaptability is poor, and when use need to guarantee that load is in the inclined medium position of supporting region；Three oil film wedges (three oily leaves) bearing is to stress side
Two oily rachises are slightly stronger than to variation adaptability to hold, but still have limitation, can not be suitable for multi-state and be used；Four oily rachises hold one
As be applied to the operating condition of high speed light loading and use, but it is poor to Impact direction variation adaptability when running at high speed；Tilting-pad bearing pair
Impact direction adaptability is most strong, but holding because of its structure size much larger than the fixing oil rachis of same inner diameter be applied to it can not
Some small devices, and processing cost is much higher than the sliding bearing of other several types.
Summary of the invention:
In place of overcoming above-mentioned the shortcomings of the prior art, and provide one kind six oily leaf sliding axle
It holds, it solves sliding used in some multi-state operations or the geared machine equipment persistently influenced by external alternating load
The Impact direction of bearing can change with operating condition or mechanical periodicity, but used sliding bearing structure form is to stress side
To this poor technical problem of adaptability of variation.
The technical solution adopted by the present invention are as follows: the oily leaf sliding bearing of one kind six, including bearing body and bearing metal, bearing
Ontology inner ring is connect with bearing metal, and bearing metal is Nian Jie with bearing body by static or rotary casting mode, bearing body
On set there are six bearing fuel feed hole, bearing body is divided into six bearing oil leaves by bearing fuel feed hole, two adjacent bearing oil leaves it
Between be machined with bearing drain pan.
The bearing drain pan along bearing body axially through.
The bearing fuel feed hole equal distribution is on bearing body.
The bearing fuel feed hole is unequal to be distributed on bearing body.
The beneficial effects of the present invention are: this six oily leaf sliding bearing is to mechanical equipment from starting to declared working condition continuous running
The Impact direction occurred in the process changes adaptable, and bearing film maximum temperature is lower than when operation under such state
Other types sliding bearing.The six oily leaf sliding bearing is applicable to linear velocity maximum up to 80m/s, and bearings ratio to press maximum is reachable
The operating condition of 1.5Mpa uses.
Detailed description of the invention:
Fig. 1 is the radial cross-section of bearing fuel feed hole equal distribution of the present invention；
Fig. 2 is the axial sectional view of bearing fuel feed hole equal distribution of the present invention；
Fig. 3 is the radial cross-section of the unequal distribution of bearing fuel feed hole of the present invention.
Specific embodiment:
Referring to each figure, the oily leaf sliding bearing of one kind six, including bearing body 1 and bearing metal 2,1 inner ring of bearing body and bearing
Alloy 2 connects, and bearing metal 2 is Nian Jie with bearing body 1 by static or rotary casting mode, and bearing body 1 is equipped with several
Bearing body 1 is divided into several bearing oil leaves 5 by a bearing fuel feed hole 3, bearing fuel feed hole 3, between two adjacent bearing oil leaves 5
It is machined with bearing drain pan 4.The bearing drain pan 4 along bearing body 1 axially through.The bearing fuel feed hole 3 is impartial
It is distributed on bearing body 1.The bearing fuel feed hole 3 is unequal to be distributed on bearing body 1.
Bearing drain pan 4 is along bearing axially through being omitted the oil inlet slot structure that other types fixing oil rachis is held.
Six bearing oil leaves 5 on six oily leaf sliding bearings are usually in uniformly distributed arragement construction, when all directions shaft strength is big
It is small six oily leaves to be designed as non-uniformly distributed arragement construction when differing greatly.The sliding bearing is to mechanical equipment from starting to volume
Bearing oil when determining the adaptable of the Impact direction variation occurred during operating condition continuous running, and being run under such state
Film maximum temperature is lower than other types sliding bearing.
When the mechanical equipment operation installed, a part of lubricating oil flows into bearing drain pan 4 by bearing fuel feed hole 3 and goes forward side by side one
Step flows into the gap between bearing oil leaf 5(bearing and axis), and dynamic pressure oil film is formed between bearing and axis；A part of lubricating oil is logical
Oil sump or hydraulic system that bearing drain pan 4 is back to mechanical equipment are crossed, mainly plays a part of integrally to cool down sliding bearing.
Referring to Fig. 3, the unbalance stress in bearing multiple directions, there are when maximum weighted Fmax and minimum stress Fmin,
And six bearing oil leaves 5 can be revised as non-uniformly distributed arrangement form when differing greatly by numerical value.
For stress Fmax maximum in all directions, it is possible to increase a certain bearing oil leaf 5, and the stress is acted on into the oil leaf
Inclined medium position；For stress Fmin the smallest in all directions, it can correspond to and reduce bearing oil leaf 5；Stress on remaining direction
It can be disposed on remaining four oily leaves and include that angle carries out local directed complete set to oily leaf according to stress size.
The six oily leaf sliding bearing passes through dynamic pressure sliding axle calculation procedure iterative analysis: workable bearing peripheral velocity
Maximum reachable 80m/s, the corresponding bearings ratio to press maximum of the stress of all directions is up to 1.5Mpa；It is applicable to multi-state operation or holds
The continuous geared machine equipment influenced by external alternating load.
In conclusion this six oily leaf sliding bearing occurs mechanical equipment from starting to during declared working condition continuous running
Impact direction variation it is adaptable, and under such state run when bearing film maximum temperature lower than other types cunning
Dynamic bearing.The six oily leaf sliding bearing is applicable to linear velocity maximum up to 80m/s, fortune of the bearings ratio to press maximum up to 1.5Mpa
Row operating condition uses, the geared machine equipment for being applicable to multi-state operation or persistently being influenced by external alternating load.
