Embodiment
The present invention core be to provide a kind of locomotive test differential gear housing, the device is used for locomotive test, and can
Meet that the requirement of two kinds of conditions is tested in straight line test with bend.In addition, another core of the present invention is the provision of one kind and included
The locomotive bed of locomotive test differential gear housing.
In order that those skilled in the art more fully understands technical scheme provided by the present invention, below in conjunction with accompanying drawing
Locomotive test differential gear housing provided by the present invention is described in detail with specific embodiment.
As shown in figure 1, it is the cross-sectional view of the locomotive test differential gear housing provided during institute of the present invention.The present invention
Designed differential gear housing has specifically included input shaft 1 and output shaft 2, and both are located along the same line and the mutual company of rotation
Connect, relative rotation can be realized between the two.The first planetary gearsets 3, the first planetary gearsets 3 have been set with input shaft 1
It can be reduced by the rotating speed that the engagement of multi-stage gear inputs input shaft 1；The second planetary gearsets 4 are set with output shaft 2,
First planetary gearsets 3 and the second planetary gearsets 4 intermeshing be driven, and the number of teeth at different levels between two gear trains it is identical,
Gear ratio is also identical, passes through the raising speed of the second planetary gearsets 4 again after the reduction of speed of the first planetary gearsets 3, rotating speed is by a drop
One liter, spread out of by output shaft 2；The outside of the second ring gear 41 engagement in second gear group 4 sets buncher 5, speed governing electricity
Machine 5 can control the second ring gear 41 to rotate.
When carrying out straight line test, buncher 5 is on-position, and the second ring gear 41 of control is fixed, the second planet
Second planetary gear of gear train 4 is as driving wheel, and the second sun gear drives output shaft 2 to be used as driven pulley, due to the first planet tooth
Wheel group 3 is identical with the gear ratio that the second planetary gearsets 4 are at different levels, therefore can ensure the rotating speed between input shaft 1 and output shaft 2
Keep identical, meet to be reached during straight line experiment 1:1 gearratio, input shaft 1 and the synchronous axial system of output shaft 2.When entering
Buncher 5, which rotates, when row bend is tested drives the second ring gear 41 to rotate, now the second planet in the second planetary gearsets 4
Wheel is used as driving wheel simultaneously with the second ring gear 41, while drives the second sun gear to rotate, under the compound action of two rotations
The rotating speed of output shaft 2 is controlled, the rotating ratio of regulation input shaft 1 and output shaft 2, meets the condition that bend is tested.And speed governing
Motor 5 by adjusting the rotating speed of itself, can coordinate the rotating speed of regulation output shaft 2 with the second planetary gear, realize various rotating speed ratio
Change.
, will in order to ensure the absolute synchronization of rotating speed between the first planetary gearsets 3 and the second planetary gearsets 4 in the present invention
First planet carrier 32 and the second planet carrier 42 are fixedly connected to form an entirety by sleeve pipe 30, sleeve pipe 30 be enclosed on input shaft 1 with
The outside of output shaft 2, the rotation of input shaft 1 and output shaft 2 is had no effect on,
The first sun gear in first planetary gearsets 3 is made as driving wheel, the first planetary gear as driven pulley by rotating
With on the second planetary gear being delivered in the second planetary gearsets 4.In order that transmission is more efficient, by the first planetary gearsets
The first ring gear 31 in 3 is fixedly installed, and the first ring gear 31 can not rotate, and the first ring gear 31 is fixedly installed and can be also easier
Input shaft 1 is set to keep synchronous axial system with output shaft 2.Turn because the second ring gear 41 needs to realize by the drive of buncher 5
Move, it is necessary to keep good slip to act on, therefore the second ring gear 41 is rotatably mounted around the second planet carrier 42 by bearing
On.The second planet carrier 42 guarantees generation and rotated well also by bearing holder (housing, cover) on output shaft 2 simultaneously.In the first row
The slip cap of carrier 32 is connected with input shaft 1 by floating bushing on input shaft 1, the first planet carrier 32 is also produced flat
Sliding rotation.Due to being not provided with bearing, it is unstable to reduce caused by machining accuracy, rigging error etc. engagement, is carried with this
In the life-span of high gear, reduce noise.
A centrifugal force can be produced when crossing bend due to locomotive, so being needed during experiment by input shaft 1 or output
Axle 2 applies the influence of a thrust or pulling force simulation centrifugal force to locomotive operation, in order to ensure the biography of axial thrust or pulling force
Pass, one end for abutted between input shaft 1 and output shaft 2, being slidably connected sets thrust bearing, it is ensured that push-pull effort it is effective
Transmit.
Need to keep the wheel of locomotive both sides to keep synchronous respectively with input shaft 1 and output shaft 2 during experiment, in input shaft 1
Rail wheel 6 is set with symmetrically fixed on output shaft 2, for limiting the motion of locomotive wheel, between input shaft 1 and output shaft 2
Two rail wheels 6 are set respectively, matched with the size of wheel, a wheel can be transported between two adjacent rail wheels 6
It is dynamic.When applying axial thrust to output shaft 2, thrust output shaft 2 is transferred to the rail wheel 6 on output shaft 2, on output shaft 2
Rail wheel 6 is bonded with the wheel of side, transferring axial thrust.When applying a pulling force to output shaft 2, pulling force passes through output shaft
2nd, thrust bearing input shaft 1 is delivered to the rail wheel 6 on input shaft 1, remakes with the wheel to locomotive.
Further, because the weight of locomotive is very big, rail wheel 6 needs to bear the weight of whole locomotive at the trial, in order to
Avoid producing input shaft 1 and output shaft 2 shearing force of radial direction, can be set respectively close to end in input shaft 1 and output shaft 2
Bearing block 7, to ensure stress balance, improve the stability of transmission.
The first travelling gear 51 is set with the rotating shaft of buncher 5, avoids using shaft joint, to reduce whole device
Volume, in order to control the rotary speed precision that buncher 5 is provided, it can be set between the ring gear 41 of buncher 5 and second
Second travelling gear 52, the second travelling gear 52 connect the outside tooth of 5 and second ring gear of buncher 41 respectively as breast wheel.
Buncher 5 is slowed down by itself, then passes through the first travelling gear 51, the second travelling gear 52, the second ring gear 41, the second row
The transmission of carrier 42 drives output shaft 2, if overall ratio is 193.4, the control accuracy of buncher 5 is 2r/min, then exports
The running accuracy of axle 2 is ± 0.01r/min, you can realize output shaft 2 and input shaft 1 when bend is tested differential precision≤
0.02r/min requirement.Above-mentioned data are only a kind of citing, and the specific number of teeth can be selected with gear ratio according to practical application
Select, be not defined herein.
Further, in order that the volume of the device reduces, by the first planetary gearsets 3 and the second planetary gearsets as far as possible
4 are arranged in same housing, and also the first travelling gear 51 and the second travelling gear 52 can be arranged in same housing.
In addition, present invention also offers a kind of locomotive test stand, include above-mentioned locomotive test differential gear housing, Neng Goutong
When provide straight line test with bend test, filled up the blank of technique.
