Abstract
Disclosed is a clearance measuring device used for an axle suspension bearing in a locomotive axle box body. An electronic scale is used for lifting the axle box body. When a reading of the electronic scale is critical to the sum of the weights of an axle box assembly, a driven gear, a vehicle axle and the like, the distance of axial movement of the axle box body is the clearance of the axle suspension bearing. In the entire measuring process, no displacement occurs when a dial gage is used for measuring a non-toothed end bearing, and otherwise, the result is invalid. Since an axle box body motor is equipped with bolt holes and two ends withstand uniform force, the axle box body will not be elastically deformed, and thus the accuracy of measurement results is ensured.
Description
Technical field
The utility model belongs to locomotive inspection and repair technical field, relates generally to a kind of device of measuring axle suspension bearing play in locomotive axle-hang box.
Background technology
The method of existing measurement axle suspension bearing play mainly acts on axle suspension bearing box motor suspension rod place by a crowbar, the component that produces Z-direction moves up axle suspension bearing box, mobile distance shows by magnetic base dial gauge, reading is actual measurement axle suspension bearing play value, but produce the component of X-axis negative direction simultaneously, because axle suspension bearing box is half axle hung type, this component can cause the center line in axle suspension bearing box bearings at both ends chamber no longer to overlap, axle suspension bearing box can produce certain elastic deformation, takes axle suspension bearing play value and the actual value of this kind of process means actual measurement can produce deviation.
Utility model content
For solving the problems of the technologies described above, the utility model provides the measuring device for windage that in a kind of vehicle axle box body, axle suspension bearing is used, and can not make axle-hang box produce distortion in the time measuring, and deviation accurately can not occur measurement result.
The technical scheme that the utility model adopts is: the measuring device for windage that in vehicle axle box body, axle suspension bearing is used, comprise lifting gear, electronic scales, hoist cable, magnetic support dial gauge I and magnetic support dial gauge II, the suspension hook of lifting gear is connected with electronic scales, electronic scales is connected with axle suspension bearing box by hoist cable, the magnetic support II of magnetic support dial gauge II is arranged on follower gear gear ring, the sounding rod II vertical top of 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, the sounding rod I vertical top of magnetic support dial gauge I is pressed on bearing inner race upper surface.
Described lifting gear is loop wheel machine or overhead traveling crane.
The beneficial effects of the utility model are: steadily lift by crane axle-hang box by electronic scales, critical during in part weight sums such as axle suspension bearing box assembling, follower gear and axletrees when the reading value of electronic scales, the axially movable distance of axle suspension bearing box is axle suspension bearing play.In whole measuring process, measure non-increment bearing by dial gauge and be not subjected to displacement, otherwise result is invalid, due to two ends, axle suspension bearing box motor erection bolt hole uniform stressed, can there is not elastic deformation in axle-hang box, therefore ensured the accurate of measurement result.

Embodiment
With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:
After axle-hang box has been assembled, as Fig. 1, the electronic scales 2 that hoist cable 3 is housed is 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, axle-hang box balance while ensureing lifting, the suspension hook of overhead traveling crane is directly over axletree 12, follower gear gear ring 17 upper surfaces are used without type towel wiped clean, the magnetic support II 16 of magnetic support dial gauge II 10 is placed on follower gear gear ring 17, adjust the support bar II 15 of magnetic support dial gauge II, make sounding rod II 14 vertical tops of magnetic support dial gauge II 10 be pressed in the machined surface that axle-hang box increment flask joint 14(and axle-hang box motor mount intersect vertically) on, magnetic support dial gauge II 10 is returned to zero, rotate axle suspension bearing box 9, observe magnetic support dial gauge II 10 pointers and zero graduation and whether have skew, if there is skew will to be rotated further axle suspension bearing box 9 after pointer zeroing, until magnetic support dial gauge II 10 is not offset with zero graduation, the magnetic support I 19 of magnetic support dial gauge I 4 is placed on to axletree wheel seat 18(locomotive wheel/core wheel installation position) on, adjust the support bar I 20 of magnetic support dial gauge I 4, sounding rod I 22 vertical tops of magnetic support dial gauge I 4 are pressed on bearing inner race upper surface 21, and magnetic support dial gauge I 4 is returned to zero, slowly lift by crane electronic scales 2 with overhead traveling crane, when electronic scales 2 readings are critical, in axle suspension bearing box weight, (axle suspension bearing box assembles, the part such as follower gear and axletree weight sum) time stop lifting, rotate axle suspension bearing box 9, when find electronic scales 2 readings reduce after again with the overhead traveling crane electronic scales 2 of slinging, electronic scales 2 readings are returned critical in axle suspension bearing box weight, axle suspension bearing box 9 is fully rotated in left and right, so repeatedly, no longer change in axle suspension bearing box weight until electronic scales 2 readings are critical after rotation axle-hang box, read the reading in magnetic support dial gauge II 10, this reading is axle suspension bearing play, whole measuring process must be observed magnetic support dial gauge I 4, the pointer of magnetic support dial gauge I 4 does not allow to be offset, otherwise measurement result is invalid.In the time that the axle suspension bearing play of measuring is greater than critical field value, knock bearing inner race upper surface 21 with red copper bar, while knocking, on four of a symmetrical 90-degree point, even power knock, then remeasure axle suspension bearing play by above-mentioned work step, until the axle suspension bearing play value of measuring is in critical field; In the time that the axle suspension bearing play of measuring is less than critical field value, make axle suspension bearing play value in critical field by reducing the thickness of adjusting pad 6.
