Description
Technical field
The present invention relates to a kind of devices and methods therefor being applied to vertical height adjustment between railway vehicle gear case and linear electric motors to improve, belong to mechanical manufacturing field.
Background technology
At present the domestic guideway vehicle speed per hour running on main line railway reached 380 kilometers and more than, thus more strict designing and employing performance requriements is proposed for power system.
In existing guideway vehicle drive system, traction electric machine and gear case are all installed on below truck frame.The axle drive shaft of traction electric machine connects the pinion shaft of gear case by plunging joint, the Large Gear Shaft During of gear case be then directly sheathed on two side wheels between vehicle on.Under normal circumstances, for ensure traction electric machine and wheel between tractive force transmission and require that traction electric machine axle and pinion shaft on even keel are connected to plunging joint both sides.
According to guideway vehicle manufacturing process, bogie truck carries out processing and assembling prior to car body, is now easy to ensure that traction electric machine axle docks with the level between pinion shaft.When after the car assembling that falls, car body weight puts on truck frame and causes the change of equipment setting height(from bottom) under car, and plunging joint both sides now usually can be caused to be no longer level connection joint.Prior art lacks effectively for plunging joint adjustment connected horizontally, direct solution.
Plunging joint two ends are out-of-level will directly cause traction electric machine axle, inordinate wear between pinion shaft and the axle sleeve of plunging joint, thus causes that tractive force transmission efficiency declines, local temperature is too high and the shortening in actuating device service life.
In view of this, special proposition present patent application.
Summary of the invention
Actuating device height adjuster of the present invention and method thereof, its object is to solve above-mentioned prior art Problems existing and take the adjusting mechanism in gear case mount pad side, realize the adjustment of pinion shaft relative to the vertical height of traction electric machine axle of gear case, by simply changing pad quantity and thickness to regulate the vertical diff-H at plunging joint two ends, reach the level connection joint requirement of tractive force good communication.
Another goal of the invention is, by realizing the level connection joint at plunging joint two ends, reducing traction electric machine axle, inordinate wear between pinion shaft and the axle sleeve of plunging joint, ensureing that actuating device local heating is within rational scope, increases the service life.
For achieving the above object, described actuating device height adjuster mainly includes:
Gear case is hung on the suspension rod of the below of truck frame.Wherein,
The top of suspension rod and bottom, be connected to truck frame, gear case mount pad respectively by one group of pad and nut;
Install the traction electric machine side datum plate of a level in the bottom of traction electric machine, the vertical height of traction electric machine side datum plate distance track is A;
Install the gear box side datum plate of a level in the bottom of gear case, the vertical height of gear box side datum plate distance track is B.
As above-mentioned basic scheme feature, traction electric machine, gear case hang on below truck frame, and the vertical height adjustment in plunging joint both sides is realized by the pad quantity of gear case suspension rod and thickness.
Traction electric machine is constant relative to the vertical height of truck frame, and the present invention is the vertical height carrying out regulating tooth roller box based on this certain value of vertical height of traction electric machine.
Owing to being set on axletree in the Large Gear Shaft During of gear case, the vertical height of Large Gear Shaft During is also just relative to immobilizing, and the pinion shaft of gear case is connected to plunging joint side.For improving the accuracy regulating plunging joint both ends horizontal degree, reduce difficulty and the step that simplifies the operation when regulating vertical height, further improvement project is:
Connect the vertical below of the pinion shaft axial centre of plunging joint at gear case, gear box side datum plate is installed.
Based on the improvement of above-mentioned actuating device height adjuster, The invention also achieves following actuating device method for adjusting height:
Be set in plunging joint two side ends, when pinion shaft and traction electric machine axle are in level connection joint, the vertical diff-H of traction electric machine side datum plate and gear box side datum plate is C, i.e. C=A-B.
Measure the vertical diff-H C ' of reality of traction electric machine side datum plate and gear box side datum plate,
By regulating pad quantity or the thickness on suspension rod top, make C '=C.
Integrally be installed to truck frame at actuating device, car body fall car assembling after, use measuring tool to measure the vertical height of reality of traction electric machine side datum plate, gear box side datum plate distance track respectively, draw the vertical diff-H C ' of the reality of traction electric machine side datum plate and gear box side datum plate thus.
As C ' < C, illustrate that the pinion shaft of gear case is higher than traction electric machine axle, then directly reduce and hang the pad quantity of gear case in the suspension rod top of truck frame or thickness.
As C ' > C, illustrate that the pinion shaft of gear case is lower than traction electric machine axle, then can increase quantity or the thickness of above-mentioned pad, to meet C '=C.
As C '=C, illustrate that the pinion shaft of plunging joint both sides and traction electric machine axle are in level connection joint state, now tractive force transmission efficiency is the highest, and traction electric machine axle, wearing and tearing between pinion shaft and the axle sleeve of plunging joint are minimum.
For reaching the levelness of the above-mentioned plunging joint both sides of fine adjustment, directly can adjust the vertical height of gear case side, namely in the vertical below of pinion shaft axial centre, gear box side datum plate being installed.
To sum up content, described actuating device height adjuster and method thereof have advantage and are:
1, realize by simple change pad quantity and thickness the levelness accurately regulating plunging joint two ends, effectively improve the tractive force transmission efficiency of actuating device.
2, traction electric machine axle, inordinate wear between pinion shaft and the axle sleeve of plunging joint can be reduced, effectively accessory drive local heating and extend its service life.
