Description
Technical field
The present invention relates to wind power generator rotor rotating shaft cylindrical axle journal roundness tester.
Background technology
Detection to macrotype axes series axle journal form and position tolerance, is generally adopted three-coordinate instrument, laser tracker etc., and this type of instrument volume is big, price is high, need to use driving handling workpiece during measurement, very inconvenient, especially cannot detect when overhauling the rotating shaft of wind generator in more than 80 meters of high-altitude at all.
Owing to when processing rotating shaft, bearing guard cylindricity is overproof, then causes and occurs motor abnormal sound or vibration in running, and longtime running will affect bearing life.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of when high-altitude not undercarriage, convenient detection shaft surface height data, instruct and repair axle journal and simple in construction, axle journal roundness tester easy to detect.
The technical scheme is that axle journal roundness tester, it is characterized in that including detection annulus, around detection annulus axle center trisection, three dial gauge bearings are set, it is installed on the dial gauge in dial gauge bearing and is arranged at the protruding hands handle of detection annulus outer surface, described dial gauge bearing is sleeve-like, bottom connecting portion is connected with the through hole being opened in detection annulus outer surface, upper end is exposed detection annulus outer surface and has a screwed hole connected with endoporus at sidewall, it is connected with bolt in described screwed hole, described dial gauge bottom sleeve stretches in dial gauge bearing endoporus, the side amount head measuring bar end in sleeve flushes with detection circle ring inner surface, described sleeve bolt spinning is fixed.
As preferably, connecting portion processing in described bottom has external screw thread, and the through hole processing of detection annulus outer surface has female thread, and both spin fixing.
As preferably, the through hole of detection annulus outer surface is offered around detection annulus axle center.
Its concrete measuring principle is: detection annulus is inserted in tested axle journal, 3 dial gauges are inserted respectively in 3 dial gauge bearings, and fix with M5 screw-driving, align dial gauge 0, be slowly rotating ring with handle, observe dial gauge pointer, on the occasion of showing that axle surface is protruded, negative value shows that axle surface is recessed, reads data and notes down, after rotating 120o, on this cross section, circularity inspection amount completes. Measurement ring is moved axially certain distance, according to aforesaid operations, measures another cross section circularity data, by the measurement in the multiple cross sections to whole shaft part, just can obtain the cylindricity numerical value of axle cylindrical, provide infallible data for prosthesis shaft cylindricity.
Beneficial effects of the present invention: the present invention becomes ellipse according to rotating shaft processing owing to equipment precision or cutter reason often result in the outer circular section of axle, pear type, triangle Fructus Persicae type, and use outside micrometer numerical value when circumference all directions measure numerical value to differ unconspicuous characteristic, by using endoporus by the strict series detection detection annulus controlled encloses 3 dial gauges, just can be intuitively, accurately read out data, its simple in construction, easily operated, with low cost, it is easy to carry, when high altitude environment, operation is capable of the accurate qualitative, quantitative measurement of axle journal roundness of external circle and cylindricity.
