Description
Technical field
The utility model relates to a kind of lubrication system, particularly relates to a kind of centralized lubrication device of major axis.
Background technique
At present, axle and lubrication system thereof can be set all on many heavy mechanical equipments, make assisting agency's motion more smooth and easy, the part axle need be made the major axis form because of various requirement, and requires each position of parts all to be lubricated.Common axle and lubricating system thereof are more single, mainly comprise centralized lubrication and separately lubricated two kinds of forms.Lubricated separately i.e. many oil ducts of now seeing of parallel connection are lubricated to parts respectively more, the part processing complex procedures of this form, and man-hour is oversize, and machining tool is also needed higher requirement, and is easy to generate waste product.Centralized lubrication promptly with the series connection form by a central point to several lubricant housings fuel feeding; It is main that what adopt is the form that a plurality of minutes oil ducts of series connection are given component lubrication respectively on single oil duct; This form need use major axis to concentrate oiling, and traditional oiling mode is manual application of lubricant, is promptly refueled or lubricating grease to oilhole, oil nozzle with oil can or oil gun by the equipment operator; Oil or lubricating grease are lubricated each lubricant housings under the effect of oil pressure after injecting oilhole.The oil-can lubrication mode is because of inhomogeneous, discontinuous, no pressure of lubricants capacity and dependence operator's manual operation; So it is reliable inadequately sometimes; So only be applicable to low speed, light load and intermittently used parts or position, reach the coarse machinery that does not often use like exposed gear, chain, wire rope.Now oil guns that adopt concentrate oiling for the one-sided lubricating cup of axle more; Utilize oil pressure to make the lubricant oil in the centralized lubrication oil duct be forced into each minute oil duct respectively; But, the hand oil gun reduces successively because passing to the oil pressure of the oil duct of each minute on the major axis; The overwhelming majority lubricant oil under the effect of oil gun pressure all from first minute oil duct flow away, thereby cause other branch oil duct to be difficult to by sufficient lubrication, also caused the coefficient of losses of lubricant oil too big.
Summary of the invention
In order to overcome the above-mentioned deficiency that existing technology exists; The utility model provides a kind of major axis centralized lubrication device; This model utility is through the intermittence rotation of inner shaft core; Guarantee that all divide oil ducts to have been solved the first fen oil duct that causes because oil pressure reduces and always to have run oil by injecting oil liquid successively, and other minute oil duct lubricate less than problem.
The technological scheme that the utility model technical solution problem is adopted is: on the shoulder of the end of major axis, dial is housed; Axial long hole of axis part processing of major axis; The axle core is a long tubular structure; The end of axle core is installed a set of cups and lubricating cup successively, and said axle core is encased among the axial long hole of major axis.
Processing n and axis normal and the row that is connected with axial long hole divide oilhole on the said major axis, and the position of said minute oilhole is definite according to the required lubricated position of parts.
The elongated tubular position of said axle core is processed with n the through hole with axis normal; The axial position of through hole is corresponding with the axial position of the branch oilhole of major axis; The radial position of said through hole is distributed in 0 ° in a core, 360/n °, 2 * 360/n °, 3 * 360/n ° ... (n-1) * angle of 360/n ° on, n=2～20 wherein.
The surface Machining of said dial with the axle core the identical ball-and-socket of radial direction through hole angle; On said major axis shoulder, process a radial hole with the corresponding position of axle core circular groove; Axle spring steel ball positioning device is housed in the aperture; Said steel ball crouches in this circular groove, with moving axially of axes core.
At circular groove of tubulose position outer surface processing near axle core end; In circular groove, be provided with n little positioning hole corresponding to the position of n on the dial; Axial aperture of edge's processing of a set of cups is installed radial spring steel ball positioning device in the aperture, be used to locate the position of branch oilhole.
The beneficial effect of the utility model is: overcome inhomogeneous, discontinuous, the no pressure of existing lubricating system lubricants capacity, partly divided oil duct to be difficult to by problems such as sufficient lubrications.Most of lubricant oil is emerged from first oilhole when having solved the major axis centralized lubrication, and the difficult problem that other oilhole can not get lubricating has also solved the problem of single oil duct bad processing of part when lubricated separately.

Embodiment
Embodiment: with n=4 is example
Fig. 1 is the disclosed embodiment of the utility model; On the end shoulder of the lubricated major axis 4 of needs, dial 6 is housed; Axial long hole of axis part processing of major axis 4; Axle core 5 be a long tubular structure, and the end of axle core 5 is installed a set of cups 7 and lubricating cup 1 successively, and spool core 5 is packed among the axial long hole of major axis 4.The a set of cups 7 of axle core 5 matches with the end shoulder of major axis 4, and the axial long hole of the axis part of major axis 4 matches with the elongated tubular position of axle core 5.4 of processing and axis normal and row's minute oilhole of being connected with axial long hole on the said major axis 4, the center line of said minute oilhole is distributed in respectively apart from axle head s
1, s
2, s
3, s
4The position on.The elongated tubular position of said axle core 5 is processed with 4 through holes with axis normal, and the axial position of through hole is corresponding with the axial position of the branch oilhole of major axis 4, and the radial position of through hole is distributed on 0 °, 90 °, 180 °, 270 ° the angle of a core 5.The surface Machining circular groove of dial 6, the aperture of 0 °, 90 °, 180 °, 270 ° four angles of circular groove, installation shaft is carried out axially locating to spring steel ball fixing device 2 in the aperture; Circular groove of tubular portion outer surface processing near axle core 5 ends is provided with 4 little positioning holes corresponding to 4 positions on the dial in circular groove.Axial aperture of edge's processing of a set of cups 7 is installed radial spring steel ball positioning device 3 in the aperture, carry out radial location.
Lubricated step is: when needs oilhole of lubricated first minute, axle core 5 rotates to the corresponding s of 0 ° of angle of dial 6
1The position, make on the axle core 5 first hole and on the major axis 4 first minute oil duct at s
1The position on be communicated with because the hole on other core 5, respectively at the corresponding s of 90 ° of angles
2The position on, the s that 180 ° of angles are corresponding
3The position on, the s that 270 ° of angles are corresponding
4The position on, so other minutes oilhole all blocked, thereby realized the sufficient lubrication of first minute oilhole.
When axle core 5 was rotated to 90 ° of angles, it was unimpeded that whole axle core 5 has only the 2nd branch oilhole with major axis 4, so can lubricate the 2nd branch oil duct this moment easily like this.The rest may be inferred, realizes that 4 branch oilholes have all obtained lubricated fully on the whole major axis 4.Most of lubricant oil is emerged from first oilhole when not only having solved centralized lubrication, and the difficult problem that other oilholes can not get lubricating has also solved the problem of single oil duct bad processing of part when lubricated separately.
