The method of existing measurement axle suspension bearing play acts on axle suspension bearing box motor suspension rod place mainly through a crowbar, the component producing Z-direction makes axle suspension bearing box move up, the distance of movement is shown by magnetic base dial gauge, reading is actual measurement axle suspension bearing play value, but produce the component of X-axis negative direction simultaneously, owing to axle suspension bearing box is half axle hung type, this component can cause that the centrage in axle suspension bearing box bearings at both ends chamber no longer overlaps, axle suspension bearing box can produce certain elastic deformation, takes the axle suspension bearing play value of this kind of process means actual measurement can produce deviation with actual value.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides measuring device for windage and the measuring method thereof of axle suspension bearing in a kind of vehicle axle box body, axle-hang box will not be made to be deformed when measuring, and deviation accurately will not occur measurement result.
The technical solution adopted in the present invention is: the measuring device for windage of axle suspension bearing in vehicle axle box body, including lifting device, electronic scale, hoist cable, magnetic support dial gauge I and magnetic support dial gauge II, the suspension hook of lifting device is connected with electronic scale, electronic scale is connected with axle suspension bearing box by hoist cable, the magnetic support II of magnetic support dial gauge II is arranged on driven gear gear ring, measurement bar II vertical top making magnetic support dial gauge II is pressed on axle-hang box increment flask joint, the magnetic support I of magnetic support dial gauge I is arranged on axletree wheel seat, measurement bar I vertical top making magnetic support dial gauge I is pressed on bearing inner race upper surface.
Described lifting device is loop wheel machine or overhead traveling crane.
The measuring method of the measuring device for windage of axle suspension bearing in vehicle axle box body:
Step one, after axle-hang box has been assembled, hoist cable is bundled on axle suspension bearing box, and is connected with lifting device by electronic scale；
Step 2, the magnetic support II of magnetic support dial gauge II is placed on driven gear gear ring, measurement bar II vertical top making magnetic support dial gauge II is pressed on axle-hang box increment flask joint, magnetic support dial gauge II is returned to zero, rotate axle suspension bearing box, observe whether magnetic support dial gauge II pointer offsets with zero graduation, if offsetting, after being returned to zero by pointer, it is rotated further axle suspension bearing box, until magnetic support dial gauge II and zero graduation do not offset；
Step 3, the magnetic support I of magnetic support dial gauge I is placed on axletree wheel seat, makes measurement bar I vertical top of magnetic support dial gauge I be pressed on bearing inner race upper surface, and magnetic support dial gauge I is returned to zero；
Step 4, slowly lift by crane electronic scale with lifting device, when electronic scale reading critical in axle suspension bearing box weight time, stop lifting, continue to rotate axle suspension bearing box, after finding that electronic scale reading reduces, sling electronic scale with lifting device again, electronic scale reading is made to return critical in axle suspension bearing box weight, repeat multiple rotation axle suspension bearing box and lifting axle-hang box, until after rotation axle suspension bearing box, electronic scale reading is critical when axle suspension bearing box weight does not change, magnetic support dial gauge I does not offset simultaneously, then reading the reading on magnetic support dial gauge II, this reading is axle suspension bearing play.
The invention has the beneficial effects as follows: steadily lifted by crane axle-hang box by electronic scale, assemble in axle suspension bearing box when the reading value of electronic scale is critical, the part weight sum such as driven gear and axletree time, the distance that axle suspension bearing box moves axially is axle suspension bearing play.In whole measurement process, measuring non-increment bearing by dial gauge and be not subjected to displacement, otherwise result is invalid, owing to bolt hole two ends uniform stresseds installed by axle suspension bearing box motor, elastic deformation will not occur axle-hang box, thereby ensure that measurement result is accurate.

Detailed description of the invention
In conjunction with the drawings and specific embodiments, the present invention is illustrated:
After axle-hang box has been assembled, such as Fig. 1-2, will be equipped with the electronic scale 2 of hoist cable 3 to sling with the suspension hook of overhead traveling crane, and hoist cable 3 is arranged on axle suspension bearing box 9 two bolts hole 8 above, ensure axle-hang box balance during lifting, the suspension hook of overhead traveling crane is in the surface of axletree 12, by driven gear gear ring 17 upper surface with without type towel wiped clean, the magnetic support II 16 of magnetic support dial gauge II 10 is placed on driven gear gear ring 17, adjust the support bar II 15 of magnetic support dial gauge II, bar II 14 vertical top of measuring making magnetic support dial gauge II 10 is pressed in the axle-hang box increment flask joint 14(machined surface intersected vertically with axle-hang box motor mount) on, magnetic support dial gauge II 10 is returned to zero, rotate axle suspension bearing box 9, observe whether magnetic support dial gauge II 10 pointer offsets with zero graduation, if offsetting, after being returned to zero by pointer, it is rotated further axle suspension bearing box 9, until magnetic support dial gauge II 10 and zero graduation do not offset；The magnetic support I 19 of magnetic support dial gauge I 4 is placed on axletree wheel seat 18(locomotive wheel/core wheel installation position) on, adjust the support bar I 20 of magnetic support dial gauge I 4, measurement bar I 22 vertical top making magnetic support dial gauge I 4 is pressed on bearing inner race upper surface 21, and magnetic support dial gauge I 4 is returned to zero, electronic scale 2 is slowly lifted by crane with overhead traveling crane, when electronic scale 2 reading is critical, in axle suspension bearing box weight, (axle suspension bearing box assembles, the part weight sum such as driven gear and axletree) time stop lifting, rotate axle suspension bearing box 9, when finding to sling electronic scale 2 with overhead traveling crane again after electronic scale 2 reading reduces, electronic scale 2 reading is made to return critical in axle suspension bearing box weight, left and right fully rotates axle suspension bearing box 9, so repeatedly, no longer change until electronic scale 2 reading is critical after rotating axle-hang box in axle suspension bearing box weight, then read the reading on magnetic support dial gauge II 10, this reading is axle suspension bearing play, whole measurement process must observe magnetic support dial gauge I 4, the pointer of magnetic support dial gauge I 4 does not allow to offset, otherwise measurement result is invalid.When the axle suspension bearing play measured is more than critical field value, bearing inner race upper surface 21 is knocked with red copper bar, even power to knock on the four of symmetrical 90-degree some when knocking, then remeasure axle suspension bearing play by above-mentioned work step, until the axle suspension bearing play value measured is in critical field；When the axle suspension bearing play measured is less than critical field value, make axle suspension bearing play value in critical field by reducing the thickness of adjusting pad 6.
