Summary of the invention
The object of the invention is to, overcome the defect of the gear train assembly maintenance difficult of existing ship diesel engine fuel pump and servo oil pump, a kind of use for diesel engine gear drive being convenient to keep in repair is provided, when crankshaft gear or actuation gear damage, only oppositely need be installed by intermediate gear, quick, easy maintenance can be realized, ensure that diesel engine continues normal work at short notice again.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of use for diesel engine gear drive being convenient to keep in repair, comprise crankshaft gear, intermediate gear, actuation gear, gear of fuel pump and servo oil pump gear, described crankshaft gear passes through intermediate gear successively, actuation gear and gear of fuel pump and servo oil pump gears meshing, drive fuel pump and servo oil pump running, wherein, actuation gear is the duplicate gear be made up of the first gear and the second gear, this first gear engages with intermediate gear, second gear respectively with gear of fuel pump and servo oil pump gears meshing, it is characterized in that: described crankshaft gear is the duplicate gear be made up of conventional crankshaft gear and crankshaft gear for subsequent use, first gear of described actuation gear is the duplicate gear be made up of conventional first gear and the first gear for subsequent use, described intermediate gear is offset on the wheel hub of itself vertically.
Further, described conventional crankshaft gear is identical with crankshaft gear for subsequent use, and described conventional first gear is identical with the first gear for subsequent use.
Further, described intermediate gear when conventional position respectively with described conventional crankshaft gear and conventional first gears meshing, during the position of this intermediate gear after mirror images is installed respectively with described crankshaft gear for subsequent use and the first gears meshing for subsequent use.
Compared with prior art, the present invention is when the conventional gear failure of crankshaft gear or actuation gear, can be installed by intermediate gear mirror images, use equipment gear conversion power transmission route, thus realize the fast and convenient maintenance of gear train assembly, ensure that diesel engine continues normal work at short notice again.The present invention have structure simple, load and unload convenient, maintenance and be easy to advantage, be mainly used in the driving power transmission system of marine diesel engine servo oil pump and fuel pump.

Embodiment
Below in conjunction with the drawings and specific embodiments, the use for diesel engine gear drive being convenient to keep in repair of the present invention is described in further detail, but should limit the scope of the invention with this.
Incorporated by reference to consulting Fig. 1 and Fig. 2, the use for diesel engine gear drive that diagram is convenient to keep in repair is contained in the gear case body above bent axle, and this gear case body entirety is fixedly installed in the frame of diesel engine output terminal; The described use for diesel engine gear drive being convenient to keep in repair comprises crankshaft gear 1, intermediate gear 2, actuation gear 3, gear of fuel pump 4 and servo oil pump gear 5.Described crankshaft gear 1 is engaged with gear of fuel pump 4 and servo oil pump gear 5 by intermediate gear 2, actuation gear 3 successively, drives fuel pump and servo oil pump running.
Incorporated by reference to consulting Fig. 2 and Fig. 4, described crankshaft gear 1 is the duplicate gear (gear of the interlock that is namely fixed together coaxially) be made up of conventional crankshaft gear a and crankshaft gear b for subsequent use, and this conventional crankshaft gear a is identical with the structure, size etc. of crankshaft gear b for subsequent use.
Incorporated by reference to consulting Fig. 2 and Fig. 4, described actuation gear 3 is the duplicate gear be made up of the first gear 3A and the second gear 3B, this first gear 3A is the duplicate gear be made up of conventional first gear c and the first gear d for subsequent use, and this second gear 3B engages with gear of fuel pump 4 and servo oil pump gear 5 respectively.Described conventional first gear c is identical with the structure, size etc. of the first gear d for subsequent use.
Incorporated by reference to consulting Fig. 3 and Fig. 4, described intermediate gear 2 is offset on the wheel hub of itself vertically, and namely one end of the wheel hub of described intermediate gear 2 is partial in the position of this intermediate gear 2, thus the unusual length of wheel hub of these intermediate gear 2 both sides.
Refer to Fig. 4, when conventional position, described conventional crankshaft gear a engages with described intermediate gear 2, and intermediate gear 2 engages with described conventional first gear c simultaneously; Refer to Fig. 5, described intermediate gear 2 can unload by axle, and then be oppositely inserted in primitive axis and carry out mirror image installation, intermediate gear 2 after reinstalling on this position respectively with described crankshaft gear b for subsequent use and the first gears meshing d for subsequent use, thus conversion power transmission route, use equipment gear transmission instead, with the conventional crankshaft gear a of alternative damage or conventional first gear c.
Theory of maintenance of the present invention is as follows:
In marine diesel engine running, if the conventional gear failure of crankshaft gear 1 or actuation gear 3, gear transmission lost efficacy, and oil pump is short of power, and now main frame must be forced to parking and keeps in repair.At this moment we only need disassemble whole gear housing, then gear-box are turned, then disassemble the bearing cap of intermediate gear 2, can carry out switchable mirror picture refitting (as Fig. 3) to intermediate gear 2.Also fairly simple in gear mesh after refitting, all the other gears in gear housing, without the need to centering again, only need adjust the intermediate gear 2 of refitting; When then installing gear housing, also only the padded gear housing of need and transverse shifting gear housing just can centering intermediate gear 2 and crankshaft gears 1.
The present invention can carry out fast and convenient operation and use equipment gear instead, can ensure to continue normal work in the diesel engine short time, is mainly used in the driving transmission system of servo oil pump and fuel pump.
