Specific embodiment
To make the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.Type of the present invention is further illustrated below in conjunction with attached drawing.
A kind of 200km locomotive drives unit is run and the new structure device of experiment, and total device is in 2500x2500
It is carried out on big bottom plate, force application structure, suspended structure simulation branch is fixed including body structure, axle box pillar construction, gear-box
Support structure is conducive to the operating of tooling and the guarantee of each dimensional accuracy, and design feature is completes driving unit assembling process band
Greatly to facilitate；Locomotive actual motion suspension status is simulated, completes driving unit run-in test；Slide device is detected to complete horizontal stroke
Momentum detects.Present apparatus main parts size structure explanation：
As shown in Figure 1, a kind of 200km locomotive drives unit run and the total of the new structure device of experiment be
It is carried out on the big bottom plates of 2500x2500, is conducive to the operating of tooling and the guarantee of each dimensional accuracy.Design feature：First, to complete
Driving unit assembling process brings great convenience；2nd, locomotive actual motion suspension status is simulated, completes driving unit running-in examination
It tests；3rd, detection slide device detects to complete transverse momentum.
As shown in Fig. 2, the body structure on the one hand main supporting role realized to driving unit, while body structure is in liquid
Under the driving of press pump, driving unit is driven to be moved axially in the linear guide, to measure the axis being actually needed during transverse momentum detection
Xiang Li.In addition protection network, effective protection the linear guide environmental requirement are provided in the linear guide.
As shown in figure 3, axle box pillar construction is fixed on 2 body structure of part, to realize the support to driving unit,
The vibrations of driving unit when can effectively reduce run-in test by pressing plate and Flexible element structure simultaneously.
It is made of as shown in figure 4, gear-box fixes force application structure total detachable two parts, before motor installation,
Top half is sleeved on axle, using whole fixed force application structure dead axle, directly applies work in gear-box eckband end face
Firmly, gear-box is made to be moved left and right with respect to axle, assembles post gap value to measure bearing at this, realize and gear-box transverse momentum is examined
It surveys.
As shown in figure 5, partial suspension structure simulation support construction mainly plays limited support.Due to motor and axle
Between big neutral gear, relative position is difficult to determine in installation process, therefore Fig. 5 (left side) supporting block can fix motor front suspension
Arm, Fig. 5 (in) supporting block equipped with handle, can pull motor to be moved forward and backward, motor be made to be in correct position, and then to install motor
With shaft coupling；Fig. 5 (right side) resilient support block support gear-box front end.Total can prevent diaphragm coupling torsional deformation,
Each structure of driving unit is made to be run a correct position.
Present apparatus application method step is：
Step 1: detection adjustment gear-box transverse momentum
It first needs fixed with lower component：
Motor position adjusts：Handle bolt is hung into motor cabinet leg bolt hole, and the supporting block that motor is moved to cooperation proceeds to
Position adjustment.
The fixation of motor：The motor hanger of motor tail end is bolted with tool locating block 2.
Suspension arm：It falls on suspension arm column, motor suspension rubber arthrosis is fixed with bolt.
Gear-box is fixed：Gear-box front end sunpender junction is fallen on support base naturally, is fixed with bolt；Gear box back
The displacement of gear-box is fixed by handle.
Unclamp bolt and pressing plate that left and right sides body structure lower end is connected with big bottom plate.
Hydraulic hand-pump is driven, applies the power of 10KN to hydraulic cylinder, measures the pressure needed when bearing reclines, is acquired final
Need applied force 2.5kN.
By controlling bolt torque, apply 2.5kN between gear-box in axle (tooling), to measure at this after bearing assembling
Gap width.
Step 2: driving unit run-in test
It is proceeded as follows before driving unit run-in test：
Unload the driving force of hydraulic system；
Tighten the king-bolt on four pressing plates and four angles of left and right sides body structure and big back plate connections；
Unclamp the handle bolt on gear-box locating piece；
Connection power supply run and is tested by egulation rotating speed.
During detection adjustment gear-box transverse momentum, have to, by the fixing bolt and clamp loose under body structure, otherwise may be used
It can lead to the situation that tooling is damaged or monitoring numerical value is not allowed.
During driving unit run-in test, hydraulic system pressure is unloaded, fixing bolt and pressing plate under static housing structure,
Otherwise driving unit fever damage bearing, race and experiment may be caused to vibrate violent or safety accident.
Limited block should be equipped with by supporting 4 mounting groove both ends of the linear guide, prevent from leading due to the random stroke of inoperative factor
Cause body structure derailing.
The structure for having Geometrical Tolerance Principle in tooling is depending on being measured by professional, therefore should periodically be measured
And rigorous random dismounting.
The new structure device that a kind of 200km locomotive drives unit runs and tests disclosure satisfy that the assembling of driving unit, carry
High worker's efficiency；It realizes the direct run-in test to driving unit, saves the handling after being completed；Pass through gear-box one
The fixation force application structure of side directly applies active force in gear-box eckband end face, gear-box is made to be moved left and right with respect to axle, to survey
Obtain bearing assembling post gap value at this.The tooling has been applied to 200km Passenger Electric Locomotives at present.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, several improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
