Embodiment
2～5 describe preferred embodiment of the present utility model in detail with reference to the accompanying drawings.
Shown in Fig. 2 and 3, oil balancing unit 3 of the present utility model comprises main body 5 and extension 4, and main body 5 constitutes an annular, and the extension axially stretches out at an end of main body.In Fig. 2 and 3, reference character 1,2 identifies entrance point and outlet end respectively, and the extension 4 of oil balancing unit 3 in axial direction stretches out and ends at outlet end 2.In this preferred embodiment, main body is an annular shape.The sectional shape of this oil balancing unit can be for circular, square etc.In this preferred embodiment, as shown in Figure 2, the extension 4 of oil balancing unit is stretching out vertically near position, full circle place.
Below, to describe the working principle of oil balancing unit of the present utility model with reference to Fig. 4 and Fig. 5 A and 5B: the main body 5 of oil balancing unit 3 was arranged in the annular groove that forms on oil depression 14 and 24 bottom surfaces, and the extension 4 of oil balancing unit 3 is inserted in lubricant oil center- aisle 12 and 22, the external diameter of extension 4 and this lubricant oil center- aisle 12,22 internal diameter is basic identical, thereby sealing lubricating oil center- aisle 12,22, thus, the lubricant oil of inlet passage 11 can not resemble and directly pass through oil depression 14 of the prior art, 24 enter into lubricant oil center-aisle 12, in 22, and can only enter from the entrance point 1 of oil balancing unit 3, and under the effect of pressure, flow to the end of extension 4, it is outlet end 2, enter center-aisle 12 thus, 22, and as described above, lubricant oil is by discharge route 13,23 are discharged on the element to be lubricated.From the sectional drawing of Fig. 5 A and 5B as can be seen, lubricant oil from inlet passage 11 can only enter from the entrance point 1 of oil balancing unit 3, then shown in arrow A and B among Fig. 5 A and the 5B, lubricant oil is through arriving the outlet end 2 of oil balancing unit 3 behind the peak, therefore, the lubricating oil pressure at each root axle place is consistent substantially, this has also just guaranteed regardless of the residing pivotal position of axle, the lubricating oil pressure uniformity at each lubricating point place, therefore, each lubricating point place can obtain the lubricant oil of basic uniformity, and then has guaranteed that whole system can obtain suitable lubricating, thereby has prolonged the life-span of system.
Fig. 6 is the schematic representation of the position of lubricant oil discharge route 13 in the expression axle, as can be seen from the figure, when lubricant oil center-aisle 12 is at the highest notch, lubricant oil discharge route 13 is in highly identical with lubricant oil center-aisle 12 or highly is lower than the position of center-aisle 12, and, the horizontal position of the oil outlet 13 in hole is lower than center-aisle 12 partially, make that like this height of lubricant oil center-aisle 12 is the highest, thereby guaranteed under any circumstance the isostasy unanimity at each lubricating point place of every axle.
Certainly, top description only is exemplary, and, those skilled in the art can contemplate, do not utilize independent oil balancing unit, but be processed into the diversion cavity identical, equally can realize the purpose of this utility model as above-mentioned oil balancing unit in the end of axle.
Therefore, above specific description of the present utility model only is used for purpose for example, and do not constitute restriction of the present utility model, those skilled in the art can not deviate under the marrow of the present utility model and scope prerequisite that limits as appended claims, the utility model is made improvement or variation on various forms and the details, and these improvement or change are contained by the utility model all.
