Description
Technical field
The invention belongs to rail vehicle Split type hollow axle take turns sleeve debugging device field, be specifically related to one
For split type motor car wheel, hollow shaft sleeve is debug testing stand.
Background technology
Leading portion and the back segment of hollow shaft sleeve are respectively equipped with bearing groove, are used for loading wheel set bearing.But South Africa
The motor car wheel of 5M-M type train is to for Split type hollow shaft sleeve power transmission form, and its transmission principle is with domestic
The integral hollow shaft sleeve kind of drive is similar to, but its hollow shaft sleeve is divided into two along its own rotation axis line,
With boss is half brush element, and without boss is half window segment, and the two can fasten.This kind of split type dynamic
The hollow shaft sleeve of wheel pair can not as conventional wheel to lift, place and assemble.
As shown in Figure 1 to Figure 3, when wheel rim 6 assembles with hollow shaft sleeve, first by half-window 7 and 8 points of half brush
Body, and half-window 7 opening upwards is fixed, then, with the wheel set bearing 5-1 on axletree 5, wheel rim 6 is fixed
In one end of axletree, then by axletree 5 together with wheel rim 6 integral hoisting, wheel set bearing 5-1 is made to fall into half from top
In half-window bearing groove 7-1 in window 7.Now, wheel set bearing outer rim 5-1-1 and half-window bearing groove 7-1-1 it
Between still leave larger gap D, this clearance D controls within 0.25mm, therefore by design requirement needs
Need to use clearance gauge respectively clearance D to be carried out an acceptance inspection detection, and according to the tune of error size use different-thickness
Clearance distance is adjusted by full wafer, so that its clearance D width finally meets acceptance requirement.
Motor car wheel owing to assembling is the heaviest to assembly, after it falls into half-window bearing groove 7-1-1, along axle
Frictional force when transmission is very big, causes the microspur gap of wheel set bearing to adjust extremely difficult, it is difficult to control to adjust
Whole precision, therefore, be badly in need of a set of applicable above-mentioned assembling work of development debugs experimental bench.
Summary of the invention
Lacking special debug experimental bench to solve the hollow shaft sleeve of existing split type motor car wheel pair, it hangs
Dress, place and assemble and follow-up testing and debugging process exists many difficulties, the most uncontrollable take turns right
Between bearing and half-window bearing groove, precision is debug in gap, causes and debugs the technical problem that difficult quality ensures, this
Invention provides a kind of, for split type motor car wheel, hollow shaft sleeve is debug testing stand.

The fluting direction of the V-type groove of V-block assembly 2 is parallel.
Hollow shaft sleeve is debug testing stand to axletree 5, wheel rim by the split type motor car wheel of the concrete application present invention
6 and hollow shaft sleeve when carrying out assembling operation, first with the wheel set bearing 5-1 on axletree 5, wheel rim 6 is fixed on
One end of axletree, then by half-window 7 and half brush 8 split, and half-window 7 opening upwards of hollow shaft sleeve is sat
Fall on the V-type groove of two V-block assemblies 2.Then, then by axletree 5 together with wheel rim 6 integral hoisting,
The first wheel set bearing 5-1 is made to fall into the first half-window bearing groove 7-1 being positioned at half-window 7 one end from top, now,
Still leave larger gap D between wheel set bearing outer rim 5-1-1 and half-window bearing groove 7-1-1, and second takes turns
Bearing 5-2 is just fallen in the second half-window bearing groove 7-2 being positioned at half-window 7 other end.
The first crowbar jack 3-4-1 is inserted, to prize the first leading screw 3-5 so that it is rotate and to first with crowbar
The direction elongation at half-window bearing groove 7-1 place, until the sidewall of the first top 3-7 and wheel rim 6 is pressed close to;With same
The mode of sample makes the second leading screw 4-5 rotate and extends to the direction at the second half-window bearing groove 7-2 place, until the
The lateral wall 7-2-1 contact of two top 4-7 and the second half-window bearing groove 7-2.
Adjust the length of the second leading screw 4-5, the then axially adjustable thrust that can apply to half-window 7 further so that
Half-window 7 is along its most accurate play.Coordinate the length adjusting the first leading screw 3-5, then can apply instead to wheel rim 6
To active force, be that wheel rim 6 drives the first wheel set bearing 5-1 and axletree 5 together away from the first half-window axle
The direction holding groove 7-1 is moved.The most i.e. can accurately adjust the width of clearance D.
Measure the width of the clearance D between wheel set bearing outer rim 5-1-1 and half-window bearing groove 7-1-1 and select accordingly
Select the adjustment pad that thickness is appropriate, then adjust pad and fill in clearance D, more again the width of clearance D is entered
Row is measured and is adjusted.Repeat above-mentioned measurement and fill in the overload adjusting pad, until clearance D finally meets symbol
Close acceptance requirement, half brush 8 can be fastened with half-window 7 and be connected, complete axletree 5, wheel rim 6 and hollow
Shaft sleeve carries out assembling operation.
First angle adjustment through hole 3-7-2 or the second angle adjustment through hole 4-7-2 all with the first crowbar jack 3-4-1
The most identical, operating personnel can choose at random according to the operating space of crowbar and use.Second
Bearing 4-2 is higher than first bearing 3-2, with avoid the first leading screw 3-5 and the second leading screw 4-5 when flexible that
This interference and collision.The spacing of two installation position 1-2 that hold down assembly greatly is relatively big, and the first leading screw 3-5 can be made to stretch
Stopped by the first half-window bearing groove 7-1 time long.Two little spacing holding down assembly installation position 1-1 the most just make
Second leading screw 4-5 can withstand on the lateral wall 7-2-1 of the second half-window bearing groove 7-2 after elongation.
The half-window of hollow shaft can be supported and position by the platform with two V-block assemblies, makes utilization
Two groups of leading screws reversely with each other promote wheel rim and half-window to overcome frictional force with the most powerful thrust of offer respectively,
The microspur adjustment of displacement between axletree and half-window can be assisted and adjusted the assembling process of pad.Additionally,
This is debug testing stand and also has easy and simple to handle, with low cost, control accuracy advantages of higher.
