Description
Technical field
The present invention relates to bearing arrangement technical field, particularly a kind of supporting construction for slow-speed shaft.
Background technology
Country is constantly promoting mechanization of agriculture plantation at present, also has increasing farm machinery in different agriculture fields
Applied.Such as disk pears, disc harrow, rice transplanter equipment are usually and worked in nonirrigated farmland or paddy field in agricultural machinery, and it is driven
With load change during heavy duty, low speed and use it is big the characteristics of, because load change is big during agricultural machinery use, load compared with
Caused vibrations and impact can cause rotatable parts to wear and tear and be broken when big, such as bearing wear or gear wear, fracture.Together
When, due to its special working environment, outside mud, sand, water etc. easily enter machine internal, including bearing portion, so that plus
The abrasion of acute bearing so that reduced lifetime.When agricultural machinery is typically crop cultivation or harvesting when in use, such as often more
Bearing is changed, is not only wasted time and energy, maintenance cost is high, and serious meeting influences the work such as agro-farming.
Bearing is mainly used between support shaft and parts on shaft, and the running accuracy of holding shaft and reduction rotating shaft and supporting
Friction and wear, has a wide range of applications in agricultural machinery.Due to agricultural machinery often in heavy duty, vibrate, have the severe of impact
Worked under environment, therefore the structure of bearing is very extremely important.In the prior art, sliding bearing can meet heavy duty and load
The big operating mode of change, but sliding bearing can not provide preferably axially support；Although rolling bearing has, frictional resistance is small, open
The advantages of moving sensitive, efficiency high, lubrication simplicity and be easily changed, but its shortcoming is equally obvious, its impact resistance is poor, no
Be adapted to the low speed of agricultural machinery, heavy duty, during the big part of load change use.Therefore, need exist for one kind meet agricultural machinery heavy duty,
Bearing the need for load change is big during low speed and use.
The content of the invention
The goal of the invention of the present invention is, in view of the above-mentioned problems, providing a kind of supporting construction for slow-speed shaft, specifically to carry
The rolling bearing contacted for a kind of face, it is mainly used in agricultural machinery big with load change during heavy duty, low speed and use
Operating mode field；Its cost is lower simultaneously, more robust.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：
A kind of supporting construction for slow-speed shaft, including an axle, form load orientation hole outer ring, a pair it is close side by side
The inner ring and retainer of setting, inner ring are sleeved in outer ring and are coaxially disposed, the inner ring that the axle sleeve is arranged side by side, axle one end
The axle step of correspondence inner ring end face is set, and the other end is the helicitic texture with nut；Between described axle band nut one end and inner ring
Provided with side guard plate, side guard plate is provided with dust ring, by tightening nut so that axle step one end of axle is formed with side guard plate one end
The inner ring that is arranged side by side is extruded and compressed, the dust ring is fitted inner ring and outer ring respectively；It is characterized in that：On the inside of the outer ring
The inner slide of two ring-types being set up in parallel is circumferentially with along it, inner slide is diametrically obliquely installed outwardly；On the outside of the inner ring
The external slideway of ring-type is circumferentially with along it, the inner slide of external slideway correspondence homonymy, external slideway relative orientation inner slide is set；It is located at
Slide mass is provided between the corresponding inner slide and external slideway, the slide mass includes multiple slips for convex structure
Block, the sliding shoe is provided with the top-surface camber portion of correspondence external slideway laminating and the lower surface camber portion of correspondence inner slide laminating；On described
The curvature of curved face part is identical with the curvature of external slideway, and the axial width of the axial width more than external slideway in top-surface camber portion；It is described
The curvature in lower surface camber portion is identical with the curvature of inner slide, and the axial width of the axial width more than inner slide in lower surface camber portion；Institute
The circumferential end faces and the inner ring axis for stating sliding shoe are coplanar；The circumferential end faces of the sliding shoe with curved face part thereon and lower song
Face forms arc transition.
It is preferred that, axle step one end of the outer ring respective shaft is provided with flange, and the flange is provided with load orientation hole；Institute
End face of flange is stated to set provided with sealed groove, the sealed groove and outer ring female coaxial and more than between the endoporus of outer ring, it is described
Closure is correspondingly provided with sealed groove.
It is preferred that, the side guard plate is provided with the mounting groove of correspondence dust ring, and the dust ring is set in Y types, its one end
It is plugged in mounting groove, one end is plugged in the groove of outer ring inside edge, last one end is plugged on the recessed of inner ring outer ledge
In groove.
It is preferred that, contact area of the contacting surface product more than sliding shoe and external slideway that the sliding shoe connects with external slideway.
It is preferred that, the sliding shoe is 4-8.
It is preferred that, the external slideway is identical with the radius of curvature of inner slide.
It is preferred that, inner oil sump is circumferentially with along inner slide on the outer ring, the inner oil sump is located in the middle of inner slide；It is described
Outer oil sump is circumferentially with along external slideway on inner ring, the outer oil sump is located in the middle of external slideway.
Due to using above-mentioned technical proposal, the invention has the advantages that：
1. the present invention instead of rolling element of the prior art, it uses it by setting a slidable slide mass
Obtained bearing capacity is big, is adapted to low speed operation, can meet the big operating mode of bearing capacity change.Existing bearing roller is generally
Spherical or column, it is generally contact and a linear contact lay with the contact that Internal and external cycle is provided, although rolling effect is good, but in agricultural
Mechanical to wait other, it can not provide higher axial bearing capacity, the thrust bearing that the slide mass that the present invention is used is obtained, its roll body
The contact with Internal and external cycle is provided contacts for face, effectively increases axial bearing capacity；Rolling element is main with circle contact position up and down
At stress, point contact, linear contact lay bearing capacity are not as face contact.
2. existing bearing machining required precision is higher, such as angular contact ball bearing, and the requirement on machining accuracy of the present invention
Relatively low, slide mass quantitative requirement used at the same time is less, and 4 slide masses can just meet need of work when minimum.Due to adopting
Its bearing capacity is contacted with face big, although relative friction forces are contacted with linear contact lay more greatly compared to point, but for the agriculture of low speed operation
Industry, heave-load device etc. are in the case where there is lubrication circumstances, and the present invention is more or less the same with bearing friction power in the prior art, can meet work
It is required that.Operationally, slide mass can keep geo-stationary to relatively rotate, and it has the advantages that sliding bearing, simultaneously
Also there is bearing.
3. processing cost of the present invention is low, simple in construction, radial direction bearing capacity is big, by using face contact slide, solves existing
The deficiency that rolling bearing has in technology, can meet agricultural machinery popularization and application.
