Description
The utility model relates to a kind of instrument that is used to measure rotary machine shaft coupling deviation.
The centre deviation of rotary machine shaft coupling is most important for the safe operation of favourable turn.Deviation exceeds standard the favourable turn amplitude is increased, and jeopardizes equipment safety operation.Therefore, this deviation of favourable turn maintenance procedure strict regulations must not be greater than 0.05mm, still, existing survey instrument clumsiness, coarse and crude, the measurement data error is very big, far can not satisfy requirements of the times.Also work results in hand cramps to centering simultaneously.
Existing shaft coupling deviation survey instrument mainly contains two kinds: a kind of is the centering clamp, and a kind of is Magnetic gauge stand, below the shortcoming of these two kinds of survey instruments of ad hoc analysis.
1. the centering clamp does not have versatility, because it is the clip of being manufactured by band iron, directly is stuck on the shaft coupling.So the shaft coupling of how many kinds of specification is arranged, just needs to be equipped with the centering clamp of how many kinds of specification.
2. centering clamp dismounting inconvenience, not portable, heavy, coarse and crude.
3. the centering clamp need be used the clearance gauge measurement clearance, and measurement data is subjected to the influence of human factor very big, and clearance gauge is firmly different, and institute's data of surveying are difference just, therefore, vary with each individual with the data of centering clamp measurement, because of the time different.Error is very big.
4. when the magnetic dial gauge seat is used for the measurement of shaft coupling deviation, need be equipped with two cover Magnetic gauge stands and two cover dial gauges simultaneously.It is big to take up room, and can't use under most of occasions.
5. the support of magnetic dial gauge seat has a plurality of active junction points, produces error thereby each active junction point all might produce displacement.
6. the dial gauge on the magnetic dial gauge seat need repeatedly rotate gauge outfit when the different azimuth of shaft coupling is measured, because be fixed on dial gauge on the support on the different azimuth of shaft coupling the time, always not supine, like this, rotate gauge outfit, will cause artificial measuring error.
This shows that existing survey instrument far can not satisfy the requirement in epoch, and cause many troubles to the people.
In order to address this problem, I once designed and had applied for a kind of " shaft coupling rectifies an instrument ", application number 94219747.X, but through test of many times, be difficult to successfully, after again through more than ten times improvement, finally trial-produceed a kind of novel shaft coupling surveying instrument successfully, be the shaft coupling deviation measuring apparatus that this paper proposes, it has in essence difference in " shaft coupling rectifies an instrument ", and is existing as follows to the weaknesses analysis of " shaft coupling rectifies an instrument ":
1. the Z-shaped support of " shaft coupling rectifies an instrument " and column need to be fixed on the shaft coupling with screw, and this not only will destroy shaft coupling, and make troubles for workman's work on the spot.
2. the fixed form of the dial gauge of " shaft coupling rectifies an instrument " is improper, when rotating gauge outfit, must make dial gauge produce displacement, thereby cause artificial error.
3. therefore " shaft coupling rectifies an instrument " dismounting inconvenience is out of favour.
And the utility model that this paper proposes is through repeatedly improving and pass through the new instrument of site test.
The purpose of this utility model is that a kind of novel favourable turn shaft coupling deviation measuring apparatus will be provided, and it has distinguished advantage.Now as follows with regard to benefit analysis of the present utility model:
1. highly versatile is not subjected to the restriction of shaft coupling specification, so long as iron shaft coupling just can use.
2. volume is little, and is in light weight, is easy to carry, and dismounting is very convenient.
3. measure accurately quick.
4. when measuring, be not subjected to artificial influence, measurement data is accurate
The purpose of this utility model is achieved in that at first makes a support and a header, and a powerful magnetic patch is all respectively inlayed in their bottom.This magnetic patch can be adsorbed on support and header on the shaft coupling firmly.Because magnetic patch adopts the rare earth ferromagnetic material to make, volume is little, and magnetic force is strong, so the overall volume of support and header and magnetic patch thereof is all smaller.Because adopted magnetic patch, so when using, dismounting is very convenient, and is more preferably the restriction that magnetic patch is not subjected to the shaft coupling specification, so long as iron shaft coupling can use.Radial and axial in the support upper edge respectively have a jack, respectively inlays a magnet-wheel in the jack.Other prepares two dial gauges, add a fixed cover in advance on the table table bar of dial gauge, this fixed cover becomes tight power to cooperate with dial gauge table bar, when dial gauge table bar inserts jack, a side of this fixed cover is just identical with a side of magnet-wheel, and its surface of contact is in advance through grinding.Because fixed cover and magnet-wheel are attached together, dial gauge can not swung, but can rotate with hand.The surface of contact of magnet-wheel and fixed cover can guarantee the gauge outfit of dial gauge through after grinding, and forwards either direction to, and the data of being surveyed are all the same, because fixed cover only is added on the dial gauge table bar, does not influence moving of dial gauge pointer.The pointer of dial gauge refers on header, header is adsorbed on the favourable turn half a coupler by magnetic patch, support is adsorbed on the motor half a coupler by magnetic patch, centre deviation between favourable turn half a coupler and the motor half a coupler, be reflected in the variation of the axial and radial distance between header and the support, so, as long as measure range difference between support and the header with dial gauge, the centre deviation of shaft coupling as can be known just, owing to measure with dial gauge, direct reading, thus measure simple and direct fast, again because this programme has adopted fixed cover and magnet-wheel, dial gauge is adsorbed by magnet-wheel, need not be hand steered, thus the influence of human factor avoided fully to measuring, be accurate so measure.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the shaft coupling deviation measuring apparatus structural drawing that proposes according to utility model.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
The instrument that the utility model proposes is by forming with lower member: support 5, header 3, magnetic patch 2, magnet-wheel 9, fixed cover 8, dial gauge 7.
The bottom of support 5 and header 3 respectively studs with a magnetic patch 2.The support upper edge is radial and axial respectively a jack 10 and jack 11; Respectively stud with a magnet-wheel 9 in jack 10 and the jack 11; Support 5 is adsorbed on the motor half a coupler 13 by magnetic patch 12; Header 3 is adsorbed on the favourable turn half a coupler 1 by magnetic patch 2; Edge one fixed cover 8 on the table bar 6 of dial gauge 7.6 one-tenth tight power of this cover and dial gauge table bar cooperate.Fixed cover 8 is subjected to the absorption of the magnetic force of magnet-wheel 9, and dial gauge 7 is fixed on the support 5.The pointer 4 of dial gauge 7 refers to that on header 3, the displacement of header 3 drives the displacement of pointer 4, so dial gauge 7 video datas.
Support 5 and header 3 are transferred to the appropriate location to their spacing after being adsorbed on separately the half a coupler by magnetic patch 12 and magnetic patch 2, then motor half a coupler 13 and mechanical half a coupler are worn with screw rod, and it can be rotated together.Rotating joint, make support 5 and header 3 forward four orientation, upper and lower, left and right of shaft coupling together to, when different orientation, the centre deviation of two half a couplers is different, their deviation directly is reflected in the variation of the distance between support 5 and the header 3, measure the support when the different azimuth and the distance of header with dial gauge 7,, just can measure the deviation of shaft coupling by relatively.
