Abstract
The utility model relates to a height adjusting device for a driving device. An adjusting mechanism at one side of a gear box installing seat is adopted to realize the adjustment of the vertical direction height of a pinion shaft of a gear box relative to a traction motor shaft, the vertical direction height difference of the two ends of a shaft coupling is regulated by simply changing the number and the thickness of spacers, and the level connection requirement of good transfer of traction is achieved. The height adjusting device comprises a hanging rod which is used for hanging the gear box under a bogie frame. The top end and the bottom end of the hanging rod are respectively connected with the bogie frame and the gear box installing seat by a group of spacers and nuts. The bottom of a traction motor is provided with a horizontal traction motor side datum plate, and the bottom of the gear box is provided with a horizontal gear box side datum plate. The vertical direction height adjustment of the two sides of the shaft coupling is realized by the number and the thickness of the spacers of the hanging rod of the gear box.
Description
Technical field
The utility model relates to a kind of device that is applied to vertical height adjustment between guideway vehicle gear case and the linear electric motors to be improved, and belongs to mechanical manufacturing field.
Background technology
At present the domestic guideway vehicle speed per hour that runs on main line railway reached 380 kilometers and more than, thereby more strict design and in-use performance requirement have been proposed for power system.
In existing guideway vehicle drive system, traction electric machine and gear case all are installed on the truck frame below.The pinion shaft of the axle drive shaft of traction electric machine by plunging joint connection gear case, the Large Gear Shaft During of gear case then directly be sheathed on two side wheels between vehicle on.Under normal circumstances, for guarantee traction electric machine with take turns between the tractive force transmission require traction electric machine axle and pinion shaft on even keel to be connected in the plunging joint both sides.
According to the guideway vehicle manufacturing process, bogie truck is processed and is assembled prior to car body, and be easy to guarantee that the traction electric machine axle docks with the level between the pinion shaft this moment.After the car assembling of falling, car body weight puts on truck frame and causes the variation of equipment setting height(from bottom) under the car, and can cause the plunging joint both sides this moment usually no longer is that level connects.Prior art for plunging joint adjustment connected horizontally lack effectively, direct solution.
The plunging joint two ends are out-of-level will directly to cause inordinate wear between the axle sleeve of traction electric machine axle, pinion shaft and plunging joint, thereby cause that the tractive force transmission efficiency descends, local temperature is too high and the shortening in actuating device service life.
In view of this, the special present patent application that proposes.
The utility model content
Actuating device height adjuster described in the utility model, its design goal is to solve the problem that above-mentioned prior art exists and takes adjusting mechanism in gear case mount pad one side, realize of the adjustment of the pinion shaft of gear case with respect to the vertical height of traction electric machine axle, to regulate the vertical diff-H at plunging joint two ends, reach the horizontal connection request of tractive force good communication by simple change pad quantity and thickness.
Another design goal is, connects by the level that realizes the plunging joint two ends, and the inordinate wear between the axle sleeve of reduction traction electric machine axle, pinion shaft and plunging joint guarantees that actuating device local heating within reasonable range, increases the service life.
For realizing above-mentioned design goal, 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 are connected in truck frame, gear case mount pad by one group of pad and nut respectively;
The traction electric machine side datum plate of one level is installed in the bottom of traction electric machine, and traction electric machine side datum plate is A apart from the vertical height of track;
The gear box side datum plate of one level is installed in the bottom of gear case, and the gear box side datum plate is B apart from the vertical height of track.
As above-mentioned basic scheme feature, traction electric machine, gear case hang on the truck frame below, realize by the pad quantity and the thickness of gear case suspension rod at the vertical height adjustment of plunging joint both sides.
Traction electric machine is a unmodified with respect to the vertical height of truck frame, and this certain value of vertical height that the utility model is based on traction electric machine comes the vertical height of regulating tooth roller box.
Because the Large Gear Shaft During at gear case is set on the axletree, also just with respect to immobilizing, the pinion shaft of gear case is connected in plunging joint one side to the vertical height of Large Gear Shaft During.Regulate for improving the accuracy of plunging joint both ends horizontal degree, reduce when regulating vertical height difficulty and simplify the operation step, further improvement project is:
Connect below pinion shaft axial centre vertical of plunging joint mounting teeth roller box side datum plate at gear case.
Content to sum up, described actuating device height adjuster has advantage and is:
1, realizes the levelness of accurately regulating the plunging joint two ends by simple change pad quantity and thickness, improve the tractive force transmission efficiency of actuating device effectively.
2, can reduce inordinate wear between the axle sleeve of traction electric machine axle, pinion shaft and plunging joint, effectively the local heating of accessory drive and prolong its service life.
Description of drawings
Now in conjunction with the following drawings the utility model is described further
Fig. 1 is the scheme drawing of described actuating device height adjuster;
Fig. 2 is the scheme of installation of described suspension rod;
Fig. 3 is the vertical height adjustment scheme drawings in plunging joint two ends;
As shown in Figure 1 to Figure 3, gear case 1, truck frame 2, suspension rod 3, traction electric machine 4, plunging joint 5, track 10, gear case mount pad 11, gear box side datum plate 12, pinion shaft 13, pad 31, nut 32, traction electric machine side datum plate 41.
The specific embodiment
The traction electric machine side datum plate 41 of one level is installed in the bottom of traction electric machine 4, and traction electric machine side datum plate 41 is A apart from the vertical height of track 10.
Connect at gear case 1 below pinion shaft 13 axial centre vertical of plunging joint 5, mounting teeth roller box side datum plate 12, gear box side datum plate 12 is B apart from the vertical height of track 10.
As shown in Figure 3, be set in plunging joint 5 two side ends, when pinion shaft 13 and traction electric machine axle were in level and are connected, traction electric machine side datum plate 41 was C with the vertical diff-H of gear box side datum plate 12, C=A-B, C are the numerical value of the complete levelness in theoretic assurance plunging joint two ends.
Adopt ruler etc. measuring tool is actual and calculate, the actual vertical diff-H C ' of traction electric machine side datum plate 41 and gear box side datum plate 12,
When C '＜C, illustrate that the pinion shaft 13 of gear case 1 is higher than the traction electric machine axle, then directly reduce and hang gear case 1 in pad 31 quantity or the thickness on suspension rod 3 tops of truck frame 2.
When C '＞C, illustrate that the pinion shaft 13 of gear case 1 is lower than the traction electric machine axle, then can increase the quantity or the thickness of above-mentioned pad 31, to satisfy C '=C.
When C '=C, illustrate that the pinion shaft 13 of plunging joint 5 both sides is in horizontal coupled condition with the traction electric machine axle, this moment, the tractive force transmission efficiency was the highest, the wearing and tearing minimum between the axle sleeve of traction electric machine axle, pinion shaft 13 and plunging joint 5.
