Abstract
The utility model relates to a mechanical shaft, in particular to a corrugated shaft device. The technical scheme provided by the utility model is that the corrugated shaft device mainly consists of a corrugated shaft and a bearing bush, wherein the corrugated shaft consists of a shaft main body and a wave structure; the outer side of the shaft main body is provided with the wave structure; the wave structure and a wave structure on the bearing bush are matched for use; the middle section of the bearing bush is provided with a lubricating oil inlet channel; and lubricating oil moves in a gap between the corrugated shaft and the bearing bush to lubricate. The corrugated shaft device has the beneficial effects that as the shaft with the wave structure is adopted, the contact area between the shaft and the bearing bush is increased; all-around lubrication can be realized on the shaft by the lubricating oil, and resistance is generated through the increase of oil pressure to apply an opposite acting force to the corrugated shaft, so that the corrugated shaft does a counter motion, and the abrasion to thrust plates at both ends of the bearing bush and the corrugated shaft is reduced. The corrugated shaft device is suitable for various counter pressure tile-type shafts lubricated by the oil pressure, and zero friction is realized in the real sense.
Description
Technical field:
The utility model relates to a kind of mechanical axis, particularly a kind of corrugated shaft device.
Background technique:
Existing motivation bent axle and gland type camshaft; Its surface is smooth cylindrical body, and in its work, the pressure that relies on lubricant oil and lubricant oil to form is lubricated; Though this lubricating system can guarantee that parts normally use; But because the rotating speed of working environment is higher, its load is also bigger.
For example: the pulling force that present 430 platen dispatches from the factory is between 750 kilograms to 800 kilograms; Because pulling force is excessive; The stressed side of thrust shoe can be worn and torn in getting up early, and the opposite side thrust shoe can be because excesssive gap fall down from body, and traditional straight line is lubricated; The side that thrust shoe is stressed is because too small can not get in gap lubricated fully, and opposite side then can be accelerated the drainage of machine oil etc. because of excesssive gap.In a single day this situation takes place, and bent axle body four supporting connecting rods or the like all can cause motor to scrap because mill damage partially.The self-regualting type clutch slave cylinder is in backward always and exerts oneself now; Strength is greatly about about 10 kilograms, owing to exert oneself one direct sum thrust shoe friction during crankshaft operation backward always; Temperature rising because of the friction thrust shoe; Oil film skewness, long-time use bring certain wearing and tearing still can for thrust shoe and axle and bearing shell, have shortened the working life of thrust shoe and axle and bearing shell
Summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to existing technology, and a kind of corrugated shaft device that can reduce wear significantly is provided.
Its technological scheme is: mainly be made up of corrugated axle and bearing shell; Described corrugated axle is made up of axle main body and wave structure; The axle external side of main body is made as wave structure; The use that matches with wave structure on the bearing shell of described wave structure, the stage casing of described bearing shell is provided with the lubricant oil oil input channel, and motion is lubricated in the gap of lubricant oil between corrugated axle and bearing shell.
Above-mentioned axle two ends, corrugated are provided with thrust plate.
The method for using of a kind of corrugated shaft device, form by following steps:
(1), the lubricant oil oil input channel of lubricant oil through the bearing shell stage casing get into wave structure, through the two ends of the intermittent motion between corrugated axle and the bearing shell to corrugated axle, lubricated uniformly to the corrugated thrust plate at axle two ends;
When (2), axial motion appears in the corrugated axle; Wave structure on the axle of corrugated and the gap between the bearing shell dwindle, and the oil pressure of lubricant oil becomes big and produces resistance, thereby the corrugated axle is applied opposition; Make corrugated axle reversing motion, reduce wearing and tearing the thrust plate at bearing shell and axle two ends, corrugated.
The beneficial effect of the utility model is: owing to adopt the axle of wave structure; Having strengthened axle has the area of contact of bearing shell, and lubricant oil can be realized omnibearing lubricated to axle, becomes the big resistance that produces through oil pressure the corrugated axle applied opposition; Make corrugated axle reversing motion; Minimizing is to the wearing and tearing of the thrust plate at bearing shell and axle two ends, corrugated, be fit to various dependence by oil pressure lubricated to pressing watt formula axle, realize zero wearing and tearing of real meaning.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 be the utility model a kind of embodiment's structural drawing;
Among the last figure: corrugated axle 1, bearing shell 2, lubricant oil oil input channel 3, thrust plate 4, wave structure 5.
Embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
In conjunction with accompanying drawing 1-2, the present invention is done further description:
The utility model mainly is made up of corrugated axle 1 and bearing shell 2; Described corrugated axle is made up of axle main body and wave structure; The axle external side of main body is made as wave structure 5; The use that matches with wave structure on the bearing shell of described wave structure, the stage casing of described bearing shell is provided with lubricant oil oil input channel 3, and motion is lubricated in the gap of lubricant oil between corrugated axle and bearing shell.
Above-mentioned axle two ends, corrugated are provided with thrust plate 4.
The method for using of a kind of corrugated shaft device, form by following steps:
(1), the lubricant oil oil input channel of lubricant oil through the bearing shell stage casing get into wave structure, through the two ends of the intermittent motion between corrugated axle and the bearing shell to corrugated axle, lubricated uniformly to the corrugated thrust plate at axle two ends;
When (2), axial motion appears in the corrugated axle; Wave structure on the axle of corrugated and the gap between the bearing shell dwindle, and the oil pressure of lubricant oil becomes big and produces resistance, thereby the corrugated axle is applied opposition; Make corrugated axle reversing motion, reduce wearing and tearing the thrust plate at bearing shell and axle two ends, corrugated.
The matching gap that it is exactly axial plane and tiling that wave structure is provided with a natural phenomenon is controlled at 10; So the axle with watt axial clearance will be 20; The gap of thrust shoe is the same with axial plane with the tiling matching gap; Also be 10, carry out the transition to the limit after axially in other words, also can not hurt axial plane and tiling.Machine oil can be because a side clearance be little yet, and fuel feeding is inhomogeneous; Having strengthened axle has the area of contact of bearing shell.
In bent axle when work,, lubricant oil has the connecting rod oil line of entering from main shaft again from main oil gallery bent axle main oil gallery at first; Owing to adopt the axle of wave structure; Lubricant oil can be realized omnibearing lubricated to axle, becomes the big resistance that produces through oil pressure the corrugated axle is applied opposition, makes corrugated axle reversing motion; Minimizing realizes zero wearing and tearing of real meaning to the wearing and tearing of the thrust plate at bearing shell and axle two ends, corrugated.
Claims (2)
