Description
Technical field
The present invention relates to a kind of machine tool, be specifically related to a kind of center line to two rotors in shaft coupling in the rotating machinerys such as steam turbine, water pump, blower fan and overlap the dial gauge installation dial framework of proofreading and correct.
Background technology
Shaft coupling belongs to mechanical spare part in common use category, that two axles (main drive shaft and driven shaft) that connect in different institutions make it common rotation with the mechanical component of transmitting torque, shaft coupling is comprised of two halves, connect with main drive shaft and driven shaft respectively, general engine mostly links by means of shaft coupling and working machine.Shaft coupling is of a great variety, according to the relative position of coupled diaxon and the change conditions of position, can be divided into: 1. permanent coupling.Be mainly used in the strict centering of diaxon and the place of relative displacement does not occur at work, structure is generally simpler, easily make, and the diaxon transient speed is identical, mainly contains flange-face coupling, box coupling, clamping coupling etc.2. movable coupling.Be mainly used in the place that diaxon has deflection or relative displacement is arranged at work, can be divided into again rigidity moveable coupling and elasticity movable coupling according to the method for compensate for displacement.the mobility that rigidity moveable coupling utilizes the moving connection that consists of between the shaft coupling working part to have a direction or several directions compensates, as dental inlay shaft coupling (permission axial displacement), cross groove shaft coupling (being used for connecting parallel displacement or two very little axles of angular displacement), Hooks coupling universal coupling (being used for diaxon has larger angle of deviation or place than Angular Displacement is arranged at work), gear coupling (permission comprehensive displacement), chain coupling (having allowed radial displacement) etc., elasticity movable coupling (abbreviation spring coupling) utilizes the elastic deformation of flexible member to compensate deflection and the displacement of diaxon, flexible member also has buffering and damping property simultaneously, as Falk flexible coupling, the radial multilayer flat spring coupling, elastic ring latching shaft coupling, nylon latching shaft coupling, coupling with rubber sleeve etc.Also have some special shaft couplings, as ball cage type Hooks coupling universal coupling, circular cone bowl spring shaft coupling SWP, SWC type universal coupling with spider etc.In numerous standard shaft couplings, selecting properly is fit to the best shaft coupling of oneself needs, be related to the series of problems such as serviceability that the engineering goods axle is transmission, reliability, serviceable life, vibration, noise, energy-conservation, transmission efficiency, transmission accuracy, economy, also be related to the quality of engineering goods.
In addition main drive shaft that shaft coupling joins and driven shaft due to foozle, rigging error, alignment error, the axle stand under load produces and distortion, pedestal distortion, bearing wear, temperature variation, parts between the many factors such as relative motion can produce relative displacement.The relative displacement of this main drive shaft and driven shaft is difficult to avoid, and produces the equilibrium displacement direction but the axle under different working condition is transmission, namely axially, radial angle to and displacement big or small different.The shaft coupling off-centring common are following four kinds of situations;
1, as shown in Figure 1, S1=S2, a1=a2 two halves clutch end face is to be in not only parallel but also concentric tram, at this moment two axial lines must be positioned on straight line.
2, as shown in Figure 2, S1=S2, a1 ≠ a2 two halves clutch end face is parallel but at this moment the axis decentraction has parallel radial displacement e=(a2-a1)/2 between two axial lines.

The measuring method of dial gauge comprises single table mensuration, two table mensuration, three table mensurations and five table mensurations, now is respectively described below:
1, single table method: this method is only measured the radially reading of shaft coupling wheel hub cylindrical, does not measure the axial reading of end face, only uses a dial gauge when measuring operation, therefore claim single table method.Its installation, instrumentation plan are as shown in Figure 12,13, and the method just can judge the relative position of diaxon with a dial gauge and can calculate deviate axial and radially, also can try to achieve adjustment amount with graphical method according to the reading on dial gauge.The method of operating that single table is measured is, each quartern monumented point 1a of 90 ° that does to be separated by on the wheel hub periphery of two half a couplers, 2a, 3a, 4a and 1b, 2b, 3b, 4b.First set up dial gauge on " B " shaft coupling, make the 1a point place of contact on the periphery of " A " shaft coupling of dial gauge, then with dial plate to " 0 " position, press moving " B " shaft coupling of axle rotation direction dish, record respectively the 1a on " A " shaft coupling, 2a, 3a, the reading of 4a (wherein 1a=0), but for repetition measurement accurately and reliably several times.Bring error for fear of " A " shaft coupling periphery and axle decentraction to measurement, can be with hour indicator moving " B " and " A " shaft coupling.And then indicator bracket is located on " A " shaft coupling, in kind record 1b on " B " shaft coupling, 2b, 3b, the reading of 4b (wherein 1b=0).After measuring deviate, utilize variance analysis schematic diagram analytical approach shown in Figure 13, can draw " A " and " B " two half a couplers in the vertical direction with the various situations of horizontal direction diaxon relative space position.
2, two table mensurations (claiming again some mensurations): as shown in figure 14, measure respectively deviate on shaft coupling cylindrical and the same direction of end face with two dial gauges, namely in the radially reading on measuring certain orientation, measure the axial reading on same orientation.specific practice is: first do preliminary surveying and adjustment with the shaft coupling on the angle square machine that preparation is adjusted to hoisted in position, then doing to load onto unit clamp and dial gauge on the host computer side half a coupler of benchmark, make cylindrical and the end face of the contact sensing original host side half a coupler of dial gauge, concrete measuring method is as follows: the radially reading a1 and the axial reading s1 that first survey 0 ° of orientation with dial gauge, for the analytical calculation convenience, often a1 and s1 are adjusted into zero, then two half a couplers rotate simultaneously, often turn 90 ° and read numerical value in dial gauge, and reading value is filled out in record sheet, the outer radially reading a1 that records of circle, a2, a3, a4, record axial reading s1 in circle, s2, s3, s4, when dial gauge rotates back into zero-bit, must be consistent with former zero reading, the reading of measuring must meet following condition and just belong to correct, be a1+a3=a2+a4, s1+s3=s2+s4.By to measuring the analytical calculation of numerical value, determine that diaxon at the relative position in space, then adjusts by result of calculation.The method is used more extensive, can satisfy the installation accuracy requirement of general machine.
3, three table mensurations (claiming again two point measurement methods): three table mensurations and two table mensuration differences are to be arranged symmetrically with two dial gauges with equidistant place, axle center, as shown in figure 15, reading and axially in reading radially on measuring an orientation, survey its axial reading on a relative orientation, namely measure simultaneously the axial reading on relative two orientation, can eliminate axle play impact on axial reading when jiggering, its survey record figure as shown in the figure, three table mensuration methods are as follows: according to measurement result, get 0 °～180 ° and 180 °～0 ° two mean values of measuring axial reading on the orientation, that is:
ｓ1＝（ｓ1＇＋ｓ1＇＇）／2ｓ3＝（ｓ3＇＋ｓ3＇＇）／2；
Get 90 °～270 ° and 270 °～90 two mean values of measuring axial reading on the orientation, that is:
Pｓ2＝（ｓ2＇＋ｓ2＇＇）／2ｓ4＝（ｓ4＇＋ｓ4＇＇）／2；
S1, s2, s3, four mean values of s4 calculate the axial reading of use as each orientation, and with a1, a2, a3, four of a4 radially reading charge in same record diagram, by the drift condition of the data analysis shaft coupling in this figure, and calculate and adjust.This measuring method precision is very high, and being applicable to needs the precision of accurate centering or the machine that runs up, as steam turbine, and centrifugal compressor etc.By contrast, three table mensurations are slightly more numerous and diverse in operation and calculating than two table mensurations.
4, five table mensurations (claiming again four point measurement methods): in the radially reading on measuring an orientation, measure 0 °, 90 °, 180 °, axial reading on 270 ° of four orientation, and the mean value of getting four axial readings on its same orientation is as analyzing and the axial reading that calculates use, analyzes altogether the drift condition of shaft coupling with the radially reading in same orientation, and this method is identical with the genuine standard application characteristic.
The centering of diaxon absolutely accurate is unapproachable, machine to continuous operation requires to remain that centering is just more difficult accurately. the differential thermal expansion of each parts, the deflection of axle, the uneven wear of bearing, the uneven subsidences on the displacement that machine produces and basis etc. are all to cause the reason that is difficult for retainer shaft centering, therefore, there is a permissible variation value at regulation diaxon center when planing machine, and this is also needed when shaft coupling is installed.From angle of assembling, as long as can guarantee coupler safety transmitting torque reliably, the deviate of diaxon center permission is larger, more easily reaches requirement during installation.But from the installation quality angle, the diaxon centerline deviation is less, centering more accurately, the operation of a machine situation better, serviceable life is longer, therefore needs the shaft coupling alignment instrument that utilizes frequently to adjust.
the above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, anyly be familiar with the technician of this patent within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned prompting is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the present invention program's scope.
