Embodiment
For the purpose, technological scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
Referring to Fig. 1 and Fig. 2.The pneumatic clutch gearbox of internal combustion locomotive accessory drive system of the present embodiment, transmission shaft 10 is installed on the gearbox casing 24 by bearing 34, gear 6 on transmission shaft 10 the inners and 7 engagements of the gear on the hollow shaft 19, drive flange 11 and the starter-generator 30 of transmission shaft 10 outer ends join.Output shaft 21 is installed on the gearbox casing 24 by bearing, and the drive flange 27 of left end and the flake down flange 22 of right-hand member, flake down post 23 join with exciter 31 and traction electric machine ventilator 32 respectively.Hollow shaft 19 is installed on the gearbox casing 24 by roller bearing 12 and the angular contact ball bearing 5 that is set in its external diameter front end and back end, pass through spline joint between the external diameter of gear 7 and hollow shaft 19, the inside of hollow shaft 19 is processed with vertical inner spline groove 34, the outer ring of roller bearing 8 and roller bearing 9 and hollow shaft 19 inwalls are interference fit, the air-pressure chamber sealing cover 15 of hollow shaft 19 and air-pressure chamber disking body 17 utilize bolt 16 to assemble, then spiral-lock is on gearbox casing 24, form hollow shaft air-pressure chamber 33, the pore 14 on the sealing cover 15 leads to source of compressed air.Axle 20 is Spielpassung with the inner ring of roller bearing 8 and roller bearing 9, and external splines groove 35 cooperates with the inner spline groove 34 of hollow shaft 19, and the hubcap 13 that is installed in axle 20 front ends is that tightness cooperates with the inwall of hollow shaft 19.Also be processed with vertical spline on the axle 20 afterbody external diameters.The external splines groove of vertical internal spline of tailing axle 2 inside and axle 20 afterbodys is slidingly matched.The thrust spring 25 that center roller 20 produces thrust is installed in tailing axle 2 cavitys, and the inner of tailing axle 2 is installed in the support 26 by angular contact ball bearing 4, and the outer end of tailing axle 2 is equipped with elasticity adpting flange 1 and elastomeric connector body 3.
The internal combustion locomotive accessory drive system gearbox of the present embodiment has two states work.The first state: diesel engine of locomotive output shaft 28 is dragging auxiliary generator 30 and exciter 31 by gearbox 29, and 32 work of traction electric machine ventilator.The second state: cut off as required the machine power that is transmitted by diesel engine output shaft 28, the mechanical part that gearbox 29 is dragged stops, only keep the idle running of diesel engine output shaft, avoid mechanical transmission to flog a dead horse and cause frictional power loss and increase unnecessary fuel consume.Therefore, the internal combustion locomotive accessory drive system gearbox idling clutch for clutch control of the present embodiment also is divided into two kinds of situations.
At first be in the Idling Process for Diesel Engine situation, to cut off the diesel engine transmission.Connect source of compressed air, pressurized air enters hollow shaft air-pressure chamber 33 via pore 14, the pressure that pushing shaft end cap 13 and axle 20 overcome spring 25 moves to the tailing axle direction, make the external splines groove 35 of axle 20 and the inner spline groove 34 of hollow shaft 19 break away from engagement, auxiliary generating system is quit work.
The second situation is to recover the diesel engine transmission in the Idling Process for Diesel Engine situation, because hollow shaft 19 still remains static, so will consider the rotating speed matching problem of hollow shaft 19 and axle 20.At the other end of the spindle that links to each other with auxiliary generator 30 speed probe 36 is installed, is provided the speeds match signal with the rotating speed predetermined value of speed probe 36.Press the locomotive start button, starter-generator 30 drives transmission shaft 10 and hollow shaft 19 rotations, and detects the rotating speed of hollow shaft 19.The idling speed that reaches the diesel engine output shaft when the rotating speed of hollow shaft 19 for example during 430rpm, is cut off source of compressed air and is also made 33 air drafts of hollow shaft air chamber.At this moment axle 20 and hubcap 13 move back under thrust spring 25 promotes, and the external splines groove 35 of axle 20 and the inner spline groove 34 of hollow shaft 19 are meshed again, and auxiliary generating system is resumed work.
It should be noted that at last: above embodiment only in order to technological scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technological scheme.
