Technical field
The present invention relates to a kind of machine tool, be specifically related to the dial gauge installation dial framework that a kind of center line to two rotors in shaft coupling in the rotating machinerys such as steam turbine, water pump, blower fan overlaps and proofreaies and correct.
Background technology
Shaft coupling belongs to mechanical spare part in common use category, to make it common rotation with the mechanical component of transmitting torque for connecting two axles (main drive shaft and driven shaft) in different institutions, shaft coupling is comprised of two halves, connect with main drive shaft and driven shaft respectively, general engine is mostly connected by means of shaft coupling and working machine.Shaft coupling is of a great variety, according to the change conditions of the relative position of coupled diaxon and position, can be divided into: 1. permanent coupling.Be mainly used in the strict centering of diaxon requirement and the place of relative displacement does not occur at work, structure is generally simpler, easily manufacture, and 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 has at work relative displacement, according to the method for compensate for displacement, can be divided into again rigidity moveable coupling and elasticity movable coupling.The mobility that rigidity moveable coupling utilizes the moving connection forming between 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 (have larger angle of deviation or have at work the place compared with Angular Displacement for diaxon), 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, 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 applicable to the best shaft coupling of oneself needs, be related to the series of problems such as serviceability that engineering goods axle is transmission, reliability, serviceable life, vibration, noise, energy-conservation, transmission efficiency, transmission accuracy, economy, be also 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, 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, but axle under different working condition is that transmission produces equilibrium displacement direction, axially, radial angle to and the size of displacement different.Shaft coupling off-centring common are following four kinds of situations;

The measuring method of dial gauge comprises single table mensuration, two table mensuration, three table mensurations and five table mensurations, is now 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, therefore claim single table method while measuring operation.As shown in Figure 12,13, the method just can judge the relative position of diaxon and can calculate deviate axially and radially with a dial gauge, also can by graphical method, try to achieve adjustment amount according to the reading on dial gauge for its installation, instrumentation plan.The method of operating that single table is measured is, each quartern monumented point 1a of 90 ° that does to be separated by the wheel hub periphery of two half a couplers, 2a, 3a, 4a and 1b, 2b, 3b, 4b.First on " B " shaft coupling, set up dial gauge, the 1a point place of the contact that makes dial gauge on the periphery of " A " shaft coupling, then by 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), for accurately and reliably can repetition measurement several times.For fear of " A " shaft coupling periphery and axle decentraction, to measurement, bring error, 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).Measure after deviate, utilize the 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, with two dial gauges, measure respectively the deviate in shaft coupling cylindrical and the same direction of end face, in the radially reading on measuring certain orientation, measure the axial reading in same orientation.Specific practice is: the shaft coupling on the machine of first with angle square, hoisted in position being prepared to adjust is done preliminary surveying and adjustment, 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 with dial gauge, survey 0 ° of orientation, for 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 a dial gauge, and reading value is filled out in record sheet, the outer radially reading a1 that records of circle, a2, a3, a4, in circle, record axial reading s1, 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 application is more extensive, can meet the installation accuracy requirement of general machine.
3, three table mensurations (claiming again two point measurement methods): three table mensurations and two table mensuration difference Shi Yuzhou center equidistants are arranged symmetrically with two dial gauges, as shown in figure 15, reading and axially in reading radially on measuring an orientation, in a relative orientation, survey its axial reading, measure the axial reading in relative two orientation simultaneously, 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 in orientation, that is:
ｓ1＝（ｓ1＇＋ｓ1＇＇）／2ｓ3＝（ｓ3＇＋ｓ3＇＇）／2；
Get 90 °～270 ° and 270 °～90 two mean values of measuring axial reading in orientation, that is:
Pｓ2＝（ｓ2＇＋ｓ2＇＇）／2ｓ4＝（ｓ4＇＋ｓ4＇＇）／2；
S1, s2, s3, tetra-mean values of s4 calculate the axial reading of use as each orientation, and with a1, a2, a3, tetra-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 running 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 in 270 ° of four orientation, and the mean value of getting four axial readings in its same orientation is as analyzing and the axial reading that calculates use, analyze altogether the drift condition of shaft coupling with the radially reading in same orientation, this method is identical with genuine standard application characteristic.
The centering of diaxon absolutely accurate is unapproachable, the machine of continuous operation is required 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, when planing machine, there is a permissible variation value at regulation diaxon center, 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 that diaxon center allows is larger, more easily reaches requirement during installation.But from installation quality angle, diaxon centerline deviation is less, centering is more accurate, and better, serviceable life is longer for the operation of a machine situation, therefore needs the shaft coupling alignment instrument that utilizes frequently to adjust.
The above is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any technician who is familiar with this patent is not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned prompting to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the present invention program's scope.
