Abstract
A shaft neck roundness detector comprises a detection circular ring, three dial indicator supports which are arranged in a trisection mode and surround an axis center of the detection circular ring, dial indicators installed in the dial indicator supports and an embossment handle arranged on an outer surface of the detection circular ring. The dial indicator supports are in a shaft sleeve shape. A bottom end connection portion is connected with a through hole arranged on the outer surface of the detection circular ring. An upper end is exposed out of the outer surface of the detection circular ring and a side wall is provided with a screwed hole connected with an inner hole. A bolt is screwed inwardly. Each dial indicator bottom end sleeve is inserted into the inner hole of each dial indicator support. A measurement head of a measurement rod tai end in the sleeve is flushed with an inner surface of the detection circular ring. The sleeve is fixed through spinning by the bolt. The structure is simple and operation is easy. Cost is low and carrying is convenient. The detector works under a high altitude environment condition, accurate qualitative quantification measurement of shaft neck excircle roundness and cylindricity can be realized.
Description
Technical field
The utility model relates to wind power generator rotor rotating shaft cylindrical axle journal roundness tester.
Background technology
To the detection of macrotype axes series axle journal form and position tolerance, generally adopt three-coordinate instrument, laser tracker etc., and this type of instrument volume is large, price is high, need use driving handling workpiece when measurement, very inconvenient, especially in the time of the more than 80 meters rotating shaft of wind generator in maintenance high-altitude, cannot detect at all.
Due in the time processing rotating shaft, bearing guard cylindricity is overproof, occurs motor abnormal sound or vibration so cause in operational process, and long-time running will affect bearing life.
Summary of the invention
The utility model is for the deficiencies in the prior art, provides a kind of in high-altitude not undercarriage in the situation that, and the convenient shaft surface height data that detect, instruct and repair axle journal and simple in structure, axle journal roundness tester easy to detect.
The technical solution of the utility model is: axle journal roundness tester, it is characterized in that comprising detection annulus, around detecting annulus axle center trisection, three dial gauge bearings are set, be installed on the dial gauge in dial gauge bearing and be arranged at the protruding handle that detects annulus outside surface, described dial gauge bearing is sleeve-like, bottom connecting portion is connected with the through hole that is opened in detection annulus outside surface, upper end is exposed detection annulus outside surface and is had a threaded hole being communicated with endoporus at sidewall, in described threaded hole, be connected with bolt, described dial gauge bottom sleeve stretches in dial gauge bearing endoporus, in sleeve, the side amount head of sounding rod end flushes with detection circle ring inner surface, described sleeve is fixed with bolt spinning.
As preferably, described bottom connecting portion is processed with external thread, and the through hole that detects annulus outside surface is processed with internal thread, and both spin fixing.
As preferably, detect the through hole of annulus outside surface and offer around detecting annulus axle center.
Its concrete measuring principle is: detect annulus and be inserted in tested axle journal, 3 dial gauges are inserted respectively in 3 dial gauge bearings, and fix with M5 screw-driving, 0 of levelling dial gauge, with slowly swivel eye of handle, observe dial gauge pointer, on the occasion of showing axle surface protrusion, negative value shows that axle surface is recessed, and sense data is also noted down, after rotation 120o, on this cross section, circularity inspection amount completes.Measurement annulate shaft, to moving a certain distance, according to aforesaid operations, is measured to 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, for prosthesis shaft cylindricity provides authentic data.
The beneficial effects of the utility model: the utility model according to rotating shaft processing because equipment precision or cutter reason often cause the outer circular section of axle to become ellipse, pear type, triangle peach type, and use outside micrometer numerical value in the time that circumferentially all directions are measured numerical value to differ unconspicuous characteristic, by using endoporus to detect on annulus and enclose 3 dial gauges by the series of strict control, just can be intuitively, accurately sense data, it is simple in structure, easy operating, with low cost, be easy to carry, under high altitude environment condition, operation can realize the accurate qualitative, quantitative measurement of axle journal roundness of external circle and cylindricity.
