Description

Diesel locomotive wheel box right alignment detects novel frock
Technical field
The utility model relates to a kind of right alignment and detects frock, and particularly a kind of diesel locomotive wheel box right alignment detects novel frock.
Background technology
Know that by right alignment definition right alignment is: " tolerance range is that diameter is tolerance value t, and with the coaxial face of cylinder of datum axis in the zone." that is to say that right alignment is the axis variable domain of measured axis, be to be benchmark with the datum axis, be the face of cylinder that diameter is done with tolerance value t, tested axis should change in this face of cylinder.
T is very little for tolerance value, is confirmed by diameter of work and accuracy class.Generally all be micron-sized.As you know, no matter be solid shaft or tubular shaft, their axis exists really, but is can not touch, and is invisible, can't detect, and the mobility scale of axis can't detect especially so.
The method that on locomotive, usually adopts is following: for example survey the starter motor axle with respect to the right alignment that starts gear-box axle, promptly with the axis that starts gear-box axle as datum axis, survey the deviation of the axis of starter motor axle with respect to its axis.Since flange center and dead in line, thus the variation of accident axis, but survey the starter motor flange with respect to the diameter run-out of startup wheel box flange periphery and beating of end face of flange, and these two data just can be reacted coaxiality error.
Specific practice is: adopt straight steel ruler and clearance gauge to detect.At first 150 millimeters straight steel ruler is pressed against and starts on the wheel box flange periphery, fill in the gap between starter motor flange and straight steel ruler with clearance gauge, the thickness of this clearance gauge is exactly the starter motor rotor axis misalignment of axe value approximate with starting the wheel box axis.In addition, rotate the starter motor flange synchronously and start the wheel box flange, fill in clearance gauge simultaneously and measure their thickness between two flanges and calculate the gap difference.Behind suitable adjustment starter motor position, when recording between straight steel ruler between the no gap and two flanges no difference gap again, starter motor is just coaxial with respect to starting wheel box.In fact, the difference gap between gap between straight steel ruler and two flanges is when the scope of regulation, even if right alignment is qualified.
This detection means troublesome poeration, the precision extreme difference that adds clearance gauge with straight steel ruler.
The utility model content
The purpose of the utility model is: to the problems referred to above, provide a kind of diesel locomotive wheel box right alignment to detect novel frock, and simple to operate, convenient, precision is high.
The purpose of the utility model realizes through following technical proposals: a kind of diesel locomotive wheel box right alignment detects novel frock; It is characterized in that: comprise clamping spare, support and dial gauge; Wherein dial gauge has two; Be vertically set on the support end each other, dial gauge one is with vertical by the clamping axle, and dial gauge two is with vertical by the flange of clamping axle.
As optimal way, said clamping spare is made up of second annulus and first annulus, and two semicircular ring connect through fastening bolt.
The workflow of the utility model: survey the starter motor axle when starting the right alignment of gear-box axle, the frock support is being started on the gear-box axle through clamping spare clamping, be about to it and reference axis is fixed.An any place's periphery and end face of two dial gauge measuring head difference contact start motor flanges rotates the starter motor flange then synchronously and starts the wheel box flange, records the jitter values of the periphery and the end face of starter motor flange respectively with dial gauge.These two jitter values are in order to react the coaxiality error of starter motor axle with respect to the startup gear-box axle:
When end face or cylindrical jitter values are non-vanishing, can add, subtract adjustment to the adjusting pad under the starter motor mount pad or the starter motor move left and right is adjusted; When jitter values was zero, starter motor was just coaxial with respect to starting wheel box.In fact jitter values is when the scope of regulation, even if right alignment is qualified.
The beneficial effect of the utility model: simple to operate, convenient, precision is high.Through precision measurement to diesel locomotive wheel box right alignment; Coaxiality error is controlled; Can greatly reduce labour intensity, raise the efficiency, improve assembly precision, improve the quality of products, reduce faults such as the vibration of locomotive accessory drive system, different sound, bearing breakage.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark among the figure, 1 is second annulus, and 2 is fastening bolt, and 3 is first annulus, and 4 is support, and 5 is that dial gauge one, 6 is that dial gauge two, 7 is the startup gear-box axle, and 8 is the starter motor axle, and 9 for starting the wheel box flange, and 10 is the starter motor flange.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
Embodiment: as shown in Figure 1; A kind of diesel locomotive wheel box right alignment detects novel frock; It is characterized in that: comprise clamping spare, support 4 and dial gauge, wherein dial gauge has two, is vertically set on support 4 ends each other; Dial gauge 1 is with vertical by the clamping axle, and dial gauge 26 is with vertical by the flange of clamping axle; Said clamping spare is made up of with first annulus 3 second annulus 1, and two semicircular ring connect through fastening bolt 2.
Survey starter motor axle 8 when starting the right alignment of gear-box axle 7, frock support 4 is being started on the gear-box axle 7 through clamping spare clamping, be about to it and reference axis is fixed.Any place's periphery of the measuring head contact start motor flange 10 of dial gauge 1; The end face of measuring head contact start motor flange 10 correspondences of dial gauge 26; Rotate starter motor flange 10 then synchronously and start wheel box flange 9; Record the jitter values of starter motor flange 10 peripheries with dial gauge 1, dial gauge 26 records the jitter values of starter motor flange 10 end faces.These two jitter values are in order to react the coaxiality errors of starter motor axle 8 with respect to startup gear-box axle 7:
When end face or cylindrical jitter values are non-vanishing, can add, subtract adjustment to the adjusting pad under the starter motor mount pad or to the adjustment of starter motor move left and right, when the scope of jitter values, even if right alignment is qualified in regulation.
Wherein, said starter motor also can replace with exciter.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
