Detailed description of the invention
Next will be described in further detail specific embodiments of the invention by reference to the accompanying drawings.
Composition graphs 1 to Fig. 3, high pressure fuel pump 2 is installed on cylinder 1 by ring flange 3, and ring flange 3 has axis hole 31, and the pump shaft 21 of high pressure fuel pump 2 stretches into the sprocket wheel room (unmarked) of engine through axis hole 31, sprocket wheel accommodates timing wheel train in room.In sprocket wheel room, sleeve pipe 4 is sleeved on pump shaft 21, and fastening by nut 6, realizes the fixed installation of sleeve pipe 4 and pump shaft 21.Those of ordinary skill in the art can imagine easily, and sleeve pipe 4 can also be sleeved on 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 external splines of sleeve pipe 4 and the internal spline matched in clearance of helical gear 5.Driving force is passed to pump shaft 21 by the spline fitted between helical gear 5, sleeve pipe 4 by the timing chain (not shown) in sprocket wheel room, thus drives high pressure fuel pump 2 to work.Further, because sleeve pipe 4 and helical gear 5 are matched in clearance, therefore in the axial direction, helical gear 5 can slide by facing sleeve 4.The right side of helical gear 5 in the example shown, the end 71 of sliding sleeve 7 is resisted against on helical gear 5.Fixed cover 9 can be an independent component, housing 10(such as sprocket housing, the bell housing etc. for closed sprocket wheel room is fixed to by the connector such as screw, rivet), or be not an independent component but be fixed on housing 10 by integrated modes such as castings.Preferred fixed cover 9 is an independent component, adopt the modes such as screw fixing on the housing 10, or, fixed cover 9 processes external screw thread, open screwed hole on the housing 10, sprocket wheel room is screwed into from outside by fixed cover 9, fixed cover 9 pairs of springs 8 carry out pre-pressing simultaneously, when needing to overhaul drives structure, only need back out screw or fixed cover 9 is backed out, remove fixing between fixed cover 9 and housing 10, namely can by the sliding sleeve 7 of sprocket wheel indoor, spring 8 takes out, or after backing out nut 6, other part is changed, adjustment, and no longer need housing 10 to pull down, maintenance is convenient.Certainly, when fixed cover 9 is independent component, need to arrange sealing ring between fixed cover 9 and housing 10.Sliding sleeve 7 together with fixed cover 9 coaxial package, and both for matched in clearance thus sliding sleeve 7 can relatively slide axially by fixed cover 9.Between sliding sleeve 7 and fixed cover 9, be provided with the spring 8 of pre-pressing simultaneously.
With reference to figure 2, in normal operation, helical gear 5 also can bear axial force, and such as when in the situations such as engine speedup, deceleration, road bumps, helical gear 5 can produce the change of axial force due to load sudden change.The direction of axial force has two, one be towards the axial force F 1, of cylinder be towards the axial force F 2 of sprocket wheel room.In the present invention, because spring 8 is pre-compacted, therefore in an initial condition, sliding sleeve 7 pushes up to helical gear 5 by the pretightning force of spring 8, and then helical gear 5 tends to be resisted against on ring flange 3, when axial force is towards the power F1 of cylinder 1, F1 is passed on cylinder 1, and can not impact pump shaft 21.Because helical gear 5 is down rotate in working order, therefore preferred thrust plate 11 is set between ring flange 3 and helical gear 5.And composition graphs 3 is visible, thrust plate 11 realizes locating by alignment pin 12 with ring flange 3, prevents thrust plate 11 from rotating.When helical gear 5 is subject to the effect towards the axial force F 2 of sprocket wheel room, when F2 is less, F2 can be offset by the pretightning force of spring 8, therefore helical gear 5 axial direction can not slide.Even if when F2 exceedes the pretightning force of spring 8 comparatively greatly, owing to being matched in clearance between helical gear 5 and sleeve pipe 4, therefore helical gear 5 can slide towards the direction of housing 10 slightly, promote sliding sleeve 7 Compress Spring 8 further, the kinetic transformation of helical gear 5 is the potential energy of spring 8, can not occur to clash into produce noise in total.Further, because sliding sleeve 7 may move towards fixed cover 9, therefore preferably on sliding sleeve 7, open pore 72, be consistent with the air pressure inside and outside that make sliding sleeve 7.
With reference to figure 3, sliding sleeve 7 has multiple oil groove 711, for the lubrication between this end face and helical gear 5 on the end face of the end 71 of helical gear 5.Composition graphs 3 and Fig. 4, visible sliding sleeve 7 has circular hole 73, fixed cover 9 has waist-shaped hole 91, spacer pin 13 runs through circular hole 73 and waist-shaped hole 91, and therefore when helical gear 5 slides, spacer pin 13 can only slide in waist-shaped hole 91, thus it is spacing to achieve the sliding stroke of helical gear 5, clashing when preventing axial force F 2 excessive, prevents helical gear 5 landing on sleeve pipe 4, and waist-shaped hole 91 can also as fuel feed hole for the contact surface between sliding sleeve 7 and fixed cover 9 provides lubrication simultaneously.
With reference to figure 4, the diameter D1 of the shirt rim 61 of nut 6 is greater than the outer diameter D 2 of sleeve pipe 4, and therefore the restriction effect of the sliding stroke to helical gear 5 also can be played in shirt rim 61, prevents helical gear 5 from the effect of landing sleeve pipe 4.
Again get back to Fig. 3, when mounted, first, high pressure fuel pump 2 is installed on ring flange 3, pump shaft 21 is set with thrust plate 11, insert alignment pin 12 to be fixed on ring flange 3 by thrust plate 11, then overlap tubing 4, sleeve pipe 4 is set with helical gear 5, then fastening nut 6, by each part after assembling above integrally, be fixed on cylinder 1 by ring flange 3, facilitate subsequent installation to adjust.Then, install sliding sleeve 7, insert spring 8, fixed cover 9 is installed on housing 10, and when installing fixed cover 9, fixed cover 9 carries out pre-pressing to spring 8 simultaneously.Need repairing dismantle time, as long as unclamp fixed cover 9, unclamp ring flange 3, just ring flange 3, high pressure fuel pump 2, thrust plate 11, sleeve pipe 4, helical gear 5 and nut 6 integrally can be taken off, take out from sprocket wheel room and need not worry that in unloading process, part drops into sprocket wheel room, housing 10 need not be dismantled simultaneously.Need to disassemble further, renewal part time, back out nut 6, unload the dismounting that lower flange 3 just can complete total, very convenient.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
