Abstract
The invention discloses a multi-stage shift flywheel device for a test rig of a railway locomotive, and the multi-stage shift flywheel device comprises at least two flywheel shafts arranged in a box body, wherein the flywheel shafts are sequentially and coaxially arranged, and the middle part of each flywheel shaft is in a circular disc shape; and the two end parts of the flywheel shafts are shaft bodies for installing positioning bearings, and a gearshift is arranged between the two flywheel shafts and is used for realizing the combination of the flywheel shafts and meeting the speed adjustment requirements of a power-measuring motor of the test rig in the test process of the locomotives of different power levels. The problem that the difference in the moment of inertia of the flywheels needs to be realized when the tested locomotives have greater difference in different power levels and speed levels can be solved, and different moment of inertia of the flywheels can be obtained by the combination of different numbers of flywheel shafts so as to meet the test requirements of various locomotives. The multi-stage shift flywheel device is suitable for the test rig of the railway locomotive, and has the advantages of simpleness and easiness in implementation, safety and reliability, strong generality, and wide application range.

The present invention relates to the rail vehicles technical field, relate in particular to a kind of Multi-stage shift flywheel device that is applied to railway locomotive complete vehicle test bed.
Background technology
Railway locomotive complete vehicle test bed is for adapting to the test of different capacity grade, speed class locomotive, and for the flywheel gear that plays stabilized speed, storage power and use, it is also different requiring Rotary Inertia of Flywheel.Relate to different flywheel gears for different locomotives and need to process and preserve different flywheel gears, not only cause the waste of processing and raw materials cost, also to device storage, bring pressure simultaneously.
Summary of the invention
Technical matters solved by the invention is to provide a kind of Multi-stage shift flywheel device that can use the locomotive test of different brackets.
The technical solution used in the present invention is, Multi-stage shift flywheel device, comprise the flywheel shaft be installed in casing, flywheel shaft is at least two, each flywheel shaft is coaxially installed successively, and the flywheel shaft middle part is in the form of annular discs, and the flywheel shaft both ends are for the axle body of alignment bearing is installed, be provided with gearshift between flywheel shaft, gearshift is for realizing the combination between flywheel shaft.
Axle body extends on the part of bearing and is processed with male splines, described gearshift comprises: the male splines on axle body, be sleeved on axle body outer inner spline housing and control crank, male splines on inner spline housing and axle body is suitable, on adjacent two axle bodies, the length of male splines all is greater than the length of inner spline housing, inner spline housing is connected in an end of control crank simultaneously, and the control crank other end is positioned at the casing outside.
The invention has the beneficial effects as follows, flywheel shaft combination by varying number, realize the difference of Rotary Inertia of Flywheel, can realize different capacity grade, the test of friction speed grade locomotive on carload test bed, improve the versatility of testing table, and then meet the testing requirements of various kinds of vehicles, this device is simple, safe and reliable, highly versatile, applied widely.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention
In figure, be labeled as: 1-flywheel shaft, 2-male splines, 3-inner spline housing, 4-gearshift, 5-casing.
Embodiment
The invention provides a kind of railway locomotive complete vehicle test bed Multi-stage shift flywheel device, Multi-stage shift flywheel device comprises flywheel shaft 1, gearshift 4 and casing 5.Multi-stage shift flywheel device is realized the combination of a plurality of flywheel shafts 1 by gearshift 4, meet the speed governing requirement of carload test bed dynamometer motor in different capacity grade locomotive test process.
As shown in the figure, flywheel shaft 1 is installed in casing 5, the quantity of flywheel shaft 1 is at least two, each flywheel shaft 1 is coaxially installed successively, flywheel shaft 1 middle part is in the form of annular discs, and flywheel shaft 1 both ends, for for the axle body of alignment bearing is installed, are provided with gearshift 4 between flywheel shaft 1, Multi-stage shift flywheel device is realized the combination of a plurality of flywheel shafts 1 by gearshift 4, meet the speed governing requirement of carload test bed dynamometer motor in different capacity grade locomotive test process.
Gearshift 4 comprise following structure, axle body extends on the part of bearing and is processed with male splines 2, be sleeved on axle body outer inner spline housing 3 and control crank, inner spline housing 3 is suitable with the male splines 2 on axle body, on adjacent two axle bodies, the length of male splines 2 all is greater than the length of inner spline housing 3, inner spline housing 3 is connected in an end of control crank simultaneously, and the control crank other end is positioned at casing 5 outsides, is convenient to handle.Control crank is stirred inner spline housing 3, adjusts the mated condition of the male splines 2 on inner spline housing 3 and adjacent two flywheel shafts 1, has also just realized the various combination state of adjacent two flywheel shafts 1, synchronously rotates or mutually breaks away from.Inner spline housing 3 peripheries arrange annular groove, and an end of control crank inserts in recess space, realizes stirring inner spline housing 3.
When inner spline housing 3 in Fig. 1 position is all male splines 2 and inner spline housing 3 disengaged condition, only left end flywheel shaft 1 work; When left end inner spline housing 3 is stirred left, during with male splines 2 engagement on flywheel shaft 1, the common participation work of two of left parts flywheel shaft 1; In like manner, in casing all inner spline housing 3 respectively with each flywheel shaft on male splines 2 engagement the time, the interior all flywheel shafts 1 of casing 5 are all in running order, now the moment of inertia maximum.Can meet like this testing requirements of the locomotive of different capacity grade, friction speed grade.
As mentioned above, the control crank that Multi-stage shift flywheel device only needs to handle casing 5 outsides can be realized the combination of a plurality of flywheel shafts 1, control crank is provided with gear locking device and limit switch, spacing and locking mode adopts the modes such as groove is spacing, spring engaging as arranged commonly used, guarantees the security performance of operation.Multi-stage shift flywheel device of the present invention is easy to operate, simple, has reduced widely the testing table manufacturing cost, and versatility is good, wide accommodation.
