Efficient measure large bearing

To can discover when receiving money the dimension of roller bearing is wrong, can use carbolic element measuring instrument now. Can prevent the problem that in rigging a process, appears with as soon as possible from this, avoid generation to produce halt time. The process is made in current and sophisticated equipment in, if the component such as ball bearing and roller bearing is inevitable,purchase to specializationed supplier. But, manufactory home is met greatly the product quality of supplier of be enslaved to be enslaved to, blemish or life are brief wait for a problem to bear finally by mill business. In the meantime, the precision demand of the equipment such as machine and electric machinery is higher and higher, and be opposite of larger roller bearing detect the respect is put in a few problems however, often compare because of electronic measurement unit complex and costly. The replacement scheme of electronic measurement unit replaces a method as a kind, first a few companies use carbolic element to measure an instrument to undertake metrical when goods reachs a plant. Material of this kind of instrument is qualitative very light, the operation that measures a club accordingly is very simple. In the meantime, carbolic material bears fruit character durable, coefficient of expansion is small, because this can ensure,measure precision and can repeat precision. Creating precision requirement field, make with wind rotor equipment for exemple, the speed of its lamina pointed ministry can achieve 300km/h above, can achieve 1100min-1 partly on the dynamo even. What because wind-force is fluctuant,still have in addition and appear is irregular move and the effect that partial flank suffers the element such as force. Wind phone equipment (WEA) the roller bearing on rotor lamina and drive component should bear a lot of bigger than common and even moving equipment load. Accordingly, be in to the diameter 0.

6~2.

For the large bearing of 5m limits, according to different diametical grade, its machine tolerancepublic errand to allow to be hundred millimeter only. If the part is too small, criterion its bigger gap can bring about prior to wear away. If bearing is too large, chafe can increase, wear away to also can be accelerated, perhaps match at first undeserved, and the do poorly done work over again with need arduous take time, cause higher cost to produce delay from this. Equipment production manufacturer often can abandon undertaking examining to entering the bearing of the factory. The 3D that undertakes detecting to component appearance through measuring probe measures equipment (graph 1) the accurate and mechanical orgnaization that needs to have delicacy will undertake fixed to measuring club and scanning switch, this is meant should have higher investment. Laser dogs appearance value is inferior, but its precision is insufficient; And the laser interferometer that the complex calculation that uses through reflexing phase shift of beam of light will come to decide length relatively costly and appear very complex on the operation. Measurement unit of graph 1 3D is to examine a kind of method of bearing, the appearance of the component by measure probe to be measured. Probe delivers the numerical value that contacts place to obtain every time to the switch of high delicacy, but the cost of this kind of accurate machine does not poor hard hand of big, operation uses weight of steel qualitative instrument measuring an instrument is one kind replaces option, if measure screw. But also need to notice to measure precision and operation handy sex problem: On one hand, the instrument should be OK the calibration with accurate implementation; On the other hand, the adjustment that steel measures appliance character is numeric can expand because of appliance material be heated and lack fidelity, correct rise to give or take a lot of trouble quite. In addition, the steeliness weapon that needs measure is very heavy, because this relies on a person only,cannot use. This difficulty mixes ancient bronze mirror stem from charge consideration, a lot of companies are willing to believe the production quality of its component supplier assumes potential risk more. During this, people developed those who be aimed at component of big diameter of high energy field to measure appliance, easy-Metric is formed by club of a carbon fiber, the zincous alumina with two height and adjustable width is set to measure a needle on fiber club (graph 2) . Measure a needle through this, requires measure is OK by measure workbench or be made by carbolic element likewise and be applied at beforehand to the component examine on. The graph is operated one kind 2 not complex with charge not tall replacement scheme is the hand uses carbolic element measuring instrument, its material is qualitative light, not sensitive also to temperature wave motion, accordingly the measure of place adjustment is stabilized already can repeat precision to because the coefficient of expansion of carbolic element has 0 only,achieve less than of limits of 5 μ M reliably again.

4 μ M/moC, accordingly it changes to quantity of heat and do not have reaction, calibration numerical value and a lot of measure a process to also can keep for long stable. Numeric to adjusting test and verify is OK at any time and go up handily in Factory Master undertake. Practice makes clear, can repeat precision of the instrument to be able to achieve less than of limits of 5 μ M. This achieved equipment to create the firm demand to making precision apparently. In addition, it is good that uses carbolic element data has stability and anticorrosive characteristic. According to the different specifications of roller bearing, measure itself to last only 2~5min. When measure, measure instrument park workpiece to go up, undertake metrical to the biggest diameter as start with circular arc one aspect of the matter, till the deviation on dial gauge shows,return to till. When finding this to nod, can numerate directly on dial gauge as exact as the choice that gives diametical photograph error numerical value, the workpiece that can decide to whether be measured to place from this makes defective goods processing. What standard immerge deepness measures an instrument for the Easy-Metric of 300mm is the biggest measure ability to be 8m. According to user need, also can offer longer measure a needle. The charge of this kind of instrument measures systematic cost under the electron apparently, because of the follow-up cost that because the component is unqualified,this can avoid not only and causes, also can reduce initial stage to invest a level at the same time. Carbolic element measures an instrument to be able to be used at WEA to produce not only, and also can use at domains of all sorts of different expensive precision work, wait like aircraft manufacturing industry and auto industry.
