Embodiment
Next will describe in further detail specific embodiments of the invention by reference to the accompanying drawings.
In conjunction with Fig. 1 to Fig. 3, high pressure fuel pump 2 is installed on the cylinder 1 by flange plate 3, and flange plate 3 has axis hole 31, and the pump shaft 21 of high pressure fuel pump 2 passes the sprocket wheel chamber (unmarked) that axis hole 31 stretches into motor, accommodates the timing train in the sprocket wheel chamber.In the sprocket wheel chamber, sleeve pipe 4 is sleeved on the pump shaft 21, and fastening by nut 6, realizes the fixed installation of sleeve pipe 4 and pump shaft 21.Those of ordinary skills can imagine at an easy rate that sleeve pipe 4 can also be sleeved on the pump shaft 21 by the mode of interference fit, but from the angle of easy accessibility, obviously adopt nut to have more advantage.Sleeve pipe 4 has external splines, and helical gear 5 has internal spline, the internal spline Spielpassung of the external splines of sleeve pipe 4 and helical gear 5.Timing chain (not shown) in the sprocket wheel chamber passes to pump shaft 21 with driving force by the spline fitted between helical gear 5, the sleeve pipe 4, thereby drives high pressure fuel pump 2 work.And because sleeve pipe 4 is Spielpassung with helical gear 5, therefore in the axial direction, helical gear 5 sleeve pipe 4 relatively slides.The right side of helical gear 5 in diagram, the end 71 of sliding sleeve 7 is resisted against on the helical gear 5.Fixed cover 9 can be an independent member, be fixed to for example sprocket housing, flywheel casing etc. for the housing 10(of sealing sprocket wheel chamber by links such as screw, rivets), perhaps not an independent member but be fixed on the housing 10 by integrated modes such as castings.Preferred fixed cover 9 is an independent member, modes such as employing screw are fixed on the housing 10, perhaps, process outside thread at fixed cover 9, open tapped hole at housing 10, be screwed into the sprocket wheel chamber from the outside with fixed cover 9,9 pairs of springs 8 of fixed cover compress in advance simultaneously, in the time of need overhauling driving structure, only need back out screw or fixed cover 9 be backed out fixing between releasing fixed cover 9 and the housing 10, sliding sleeve 7 that namely can sprocket wheel is indoor, spring 8 takes out, perhaps backing out nut 6 backs changes other part, adjust, and no longer need housing 10 is pulled down, maintenance is convenient.Certainly, when fixed cover 9 is independent member, need between fixed cover 9 and housing 10, seal ring be set.Sliding sleeve 7 and fixed cover 9 coaxial packages together, and both can endwisely slip by relative fixed cover 9 for Spielpassung thereby sliding sleeve 7.Between sliding sleeve 7 and fixed cover 9, be provided with simultaneously the spring 8 that compresses in advance.
With reference to figure 2, in normal operation, helical gear 5 also can bear axial force, and for example under motor speedup, deceleration, road such as jolt at situation, can be because the variation that load is suddenlyd change and produced axial force on the helical gear 5.The direction of axial force has two, and one is that 1, one of axial force F towards cylinder is the axial force F 2 towards the sprocket wheel chamber.In the present invention, because spring 8 is pre-compacted, therefore under original state, the pretightening force of spring 8 pushes up sliding sleeve 7 to helical gear 5, and then helical gear 5 tends to be resisted against on the flange plate 3, be that F1 is passed on the cylinder 1, and can not impact pump shaft 21 under the situation of the power F1 of cylinder 1 in axial force.Because helical gear 5 rotates down in working order, therefore preferably between flange plate 3 and helical gear 5, thrust plate 11 is set.And in conjunction with Fig. 3 as seen, thrust plate 11 is realized the location with flange plate 3 by locating stud 12, prevents thrust plate 11 rotations.When helical gear 5 was subjected to towards the time spent of doing of the axial force F 2 of sprocket wheel chamber, when F2 hour, F2 can be offset by the pretightening force of spring 8, so can not slide on helical gear 5 axial directions.Even when F2 surpasses the pretightening force of spring 8 greatly, owing to be Spielpassung between helical gear 5 and the sleeve pipe 4, therefore helical gear 5 can slide towards the direction of housing 10 slightly, promote further compression spring 8 of sliding sleeve 7, the kinetic energy of helical gear 5 is converted into the potential energy of spring 8, bump can not take place in total produce noise.And, because therefore sliding sleeve 7 may preferably open pore 72 at sliding sleeve 7, so that the air pressure inside of sliding sleeve 7 and outside are consistent towards fixed cover 9 motions.
With reference to figure 3, sliding sleeve 7 has a plurality of oil grooves 711 on the end face of the end 71 of helical gear 5, is used for lubricating between this end face and the helical gear 5.In conjunction with Fig. 3 and Fig. 4, as seen have circular hole 73 on the sliding sleeve 7, have waist-shaped hole 91 on the fixed cover 9, position limit pin 13 runs through circular hole 73 and waist-shaped hole 91, and therefore when helical gear 5 slided, position limit pin 13 can only slide in waist-shaped hole 91, thereby realized spacing to the sliding stroke of helical gear 5, prevent clashing when axial force F 2 is excessive, prevented helical gear 5 landing on sleeve pipe 4, waist-shaped hole 91 can also provide lubricated for the surface of contact between sliding sleeve 7 and the fixed cover 9 as oil inlet hole simultaneously.
With reference to figure 4, the diameter D1 of the shirt rim 61 of nut 6 is greater than the D outer diameter 2 of sleeve pipe 4, so shirt rim 61 also can play the restriction effect to the sliding stroke of helical gear 5, prevents the effect of helical gear 5 landing from the sleeve pipe 4.
Get back to Fig. 3 again, when mounted, at first, high pressure fuel pump 2 is installed on the flange plate 3, suit thrust plate 11 on pump shaft 21, insert locating stud 12 so that thrust plate 11 is fixed on the flange plate 3, overlap tubing 4 again, suit helical gear 5 on sleeve pipe 4, fastening nut 6 then, each part after above the assembling is done as a whole, be fixed on the cylinder 1 by flange plate 3, make things convenient for the subsequent installation adjustment.Then, sliding sleeve 7 is installed, is inserted spring 8, fixed cover 9 is installed on the housing 10, simultaneously spring 8 is compressed in advance installing and fixing 9 o'clock fixed covers 9 of cover.Needing repairing when dismantling, as long as unclamp fixed cover 9, unclamp flange plate 3, just flange plate 3, high pressure fuel pump 2, thrust plate 11, sleeve pipe 4, helical gear 5 and nut 6 can be done as a whole taking off, from the sprocket wheel chamber, take out and needn't worry that part drops into the sprocket wheel chamber in the unloading process, need not dismantle housing 10 simultaneously.Need further disassemble, during renewal part, back out nut 6, unload the dismounting that lower flange 3 just can be finished total, very convenient.
Though the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only being subjected to the restriction of claim, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present invention and scope.
