The automatic detection principle of railway vehicle wheel shaft concentricity automatic tester of the present invention is as follows:
The mathematical model of the principle of railway vehicle wheel shaft concentricity automatic detection of the present invention is as shown in Figure 1.K is wheel tread point
The distance between 2 points on the same radial line with journal surface, such as the wheel tread rolling circle center of car wheel-set is not with journal surface center
There is deviation, along the circumferential direction each corresponding point in Theoretical Calculation, k1=k2=……=kn, i.e. the absolute difference p=of any k value |
kn-ki|=0.But due to assembling, mismachining tolerance and wheel to reasons such as eccentric wears in use so that the wheel of car wheel-set
Tread rolling circle center and the decentraction of journal surface center, i.e. p=| kn-ki| ≠ 0, will result in wheel in high-speed rotation and rail
Shock and vibration between face, the safety that vehicle is run and stationarity bring adverse effect, and wheel reduces to service life.Press
According to the regulation of " passenger train wheel shaft assembling maintenance and management rule ", according to the difference of running velocity, right along wheel one week
The maximum answering the absolute difference p of each point need to be within the scope of it be allowed.Calculated by model and understand k+h1+x1=h2+x2, that is,
k=h2+x2- (h1+x1).
The present invention realizes wheel by wheel axial direction clamp system and arrival is at accurately measuring position after location
Put, wheel is realized by wheel rotary drive mechanism and automatically rotates, complete the data acquisition of circumferencial direction, and can be real in measurement
Now probe being automatically positioned of (i.e. wheel tread gauge head and axle journal position gauge head).Probe be automatically positioned points horizontally and vertically two
Direction, because the gauge of China at this stage is all the international standard gauge adopting, internally range finding is relatively fixed wheel, so level side
To positioning be mainly on the basis of wheel tread rolling circle.Vertical direction: because car wheel-set spindle-type is different, have again new wheel,
Partly abrasion are taken turns and are worn away dividing of wheel, and wheel has very big difference to nominal diameter and journal surface diameter, and laser ranging probe
There is the requirement of optimal detecting distance, so enabling in the adjust automatically of vertical direction and positioning for different wheel correspondences.
The beneficial effect of technical solution of the present invention is:
1st, wheel of the present invention axial direction clamp system mainly in wheel to reaching after location in order to ensure the accuracy of measurement position
And the wheel arranging is to axial direction positioning device；Wheel is used to driving wheel and is delayed with certain speed to when monitor station position to drive mechanism
Slow-speed is moved；During measurement, wheel tread gauge head assembly vertical displacement mechanism and wheel collar position gauge head assembly vertical displacement mechanism
It is used to control gauge head upper-lower position, due to car wheel-set, in maintenance, wheel footpath size and diameter of axle size are differentiated, in order to
Gauge head is made to be in optimal measurement height in each detection, to guarantee that gauge head keeps optimal certainty of measurement, so need to be to survey
The upper-lower height of head carries out precise control.Thus, the present invention disclosure satisfy that the concentricity detection of various rail traffic vehicles wheel pair,
To not meeting the wheel of associated technical parameters requirement to carrying out further plus repair, for effectively improve passenger vehicle traveling comfort,
Stability has extremely important effect.
