Concrete, as Fig. 4, shown in Figure 9, first support 2 is provided with the projection 21 that matches with the outer ring part 332 of first oil storage tank 33, this projection 21 is an adaptive outer ring part 332, its shape can be changeful, but one section quilt projection 21 that must satisfy outer ring part 332 is sealed fully, so that lubricant oil is separated fully by projection 21.After assembling finished, the projection 21 on first support 2 was absorbed in the outer ring part 332 of first oil storage tank 33 of first friction plate 3 fully, and a section of shutoff outer ring part 332.When rotating shaft is rotated, first support 2 rotates relative to first friction plate 3, projection 21 is rotated in outer ring part 332, suppose that projection 21 ends 3321 along outer ring part 332 move to the other end 3322 directions, the lubricant oil in the oil storage tank will be under protruding 21 promotion shuttling movement.
More specifically, in this process, the lubricant oil in first oil storage tank, the 33 outer ring parts 332 flows to the second oil transportation through hole 32, then through second oil storage tank 34, gets back to the first oil transportation through hole 31, is recycled to the inner round portion 331 of first oil storage tank 33.If first support 2 is to motion in the other direction, its motion principle also with, projection 21 ends 3322 along outer ring part 332 move to the other end 3321 directions, the lubricant oil in the oil storage tank will be under the promotion of projection 21 shuttling movement.In this process, the lubricant oil in first oil storage tank, the 33 outer ring parts 332 flows to inner round portion 331, flows to second oil storage tank 34 via the first oil transportation through hole 31, is circulated to the outer ring part 332 of first oil storage tank 33 then via the second oil transportation through hole 32.
Be appreciated that outer ring part 332 can be in any a section in first oil storage tank 33.
Be appreciated that, the groove width of outer ring part 332 is wideer than inner round portion 331, the promotion of lubricant oil in 21 pairs of outer ring parts of projection when rotating on first support 2 332 in conjunction with rotating shaft, form big oil pressure, help promoting lubricant oil and circulate in whole oil storage tank, it is full all the time full in the rotating shaft movement process more to help in the inner round portion 331 lubricant oil, plays the comprehensive lubrication effect to friction plate, make rotating shaft overcome the pause point phenomenon, improved the working life of rotating shaft.
Embodiment two
Embodiment two main purpose is the torsion that increases rotating shaft, thereby need to increase the usage quantity of friction plate, it mainly comprises main shaft 1, first support 2, first friction plate 3, Sealing and nut 5, and the Sealing among this embodiment is second friction plate 6 and second support 7.As Figure 10, shown in Figure 11, main shaft 1 is identical with embodiment one with function with nut 5 positions.
The assembling sequence of this rotating shaft is: the axial wall 11 with main shaft 1 passes first support 2, first friction plate 3, second friction plate 6 and second support 7 successively earlier, is fixed on the main shaft 1 with nut 5 at last.First friction plate 3 and second friction plate 6 are fixed on the main shaft 1, do not do relative motion first support 2 and support 7 and main shaft 1 relative movement.After assembling finished, first support 2, first friction plate 3, second friction plate 6 and second support, 7 surface of contact were close to, and guarantee the unlikely leakage of lubricant oil in two friction plate oil storage tanks.
The rubbing surface of first friction plate 3 and second friction plate 6 back to, and relative first support 2 of two friction plates and second support 7 are rotary, the motion principle of embodiment's two rotating shafts is identical with embodiment one, during embodiment two rotating shaft campaign, first support 2 and second support 7 rotate together, first support 2 is provided with first projection 21, cooperates first friction plate 3; Second support 7 is provided with second projection 71, cooperates second friction plate 6.Principle is identical with embodiment one, does not do at this and gives unnecessary details.
Friction plate in the utility model rotating shaft, machine tool promptly can be processed, and be with low cost.
Be appreciated that for the different compound mode of friction plate and can be useful for the different requirement of countershaft torsion.Because the lubricant oil in the friction plate in the oil storage tank is in full state all the time, can effectively reduce the wearing and tearing of friction plate in rotating shaft is used, so, its working life can be prolonged greatly via the rotating shaft or the pivot device of the utility model friction plate combination.
In sum, more than be preferred embodiment of the present utility model only, be in order to help to understand the spirit and the main points of this patent, but be not to be used to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
