The summary can be in the spot is instant, much azimuth detects accurately the method that neck of crankshaft main shaft and brace sell a parallelism alignment error, detect principle and detect the composition of the tool, detect program and applied effect. Keyword crankshaft parallelism alignment error is mathematical label of document of TH45 of date of classification of the graph in detecting piles up B one, introductive crankshaft is being machined, in repair or installing a process, all ask to detect accurately line of center of main shaft neck and brace sell the parallelism alignment error between central line. Keep the unit with perfect system character, after crankshaft treatment is finished, examine with park the main shaft neck that the V form on flat wears the crankshaft that prop up. Measure brace to sell ceaselessly with internal diameter micrometer along axes direction next (or some brace is sold) with examine the least space between flat, push line of center of neck of cipher out main shaft and brace to sell the parallelism alignment error between central line thereby. Use unit often is used measure brace to sell at the same time reach its photograph adjacent neck of two main shaft is in 8 or the level on 16 direction is spent, next the level that the average that photograph adjacent level of neck of two main shaft spends and brace sell is spent undertake comparative, judge brace to sell roughly with the parallelism alignment error between main shaft neck. Of law of proved recipe of two kinds of check detect efficiency all inferior, and assure very hard to measure precision to be this, one kind can be in the spot is instant, various measure detect tool emerge as the times require. 2, detect methodological technology principle is same and planar inside two do not intersect linear the parallelism alignment error between, be equal to among them linear with with another linear parallel linear the parallelism alignment error between. Design and make give a kind of crankshaft to measure a tool, make the brace of crankshaft is sold with the parallelism alignment error between main shaft neck, changeover is sold for brace as linear as the some with parallel of main shaft neck the parallelism alignment error between. Sell the parallelism alignment error between with brace point-blank through measuring this, can detect give brace to sell with the parallelism between main shaft neck. 3, detect tool structure composition detects the tool is shown like attached drawing place. Pedestal and the dimension size of the roller that prop up, should measure the size of crankshaft according to what needing and decide, the centre of a circle of the pedestal after the requirement is assembled and the brace that measure crankshaft sell coincide of photograph of the centre of a circle. Slippery lever of 3 fixed position decorates the level in pedestal and lead to hang down respectively direction, ask the dimension between shoulder of axis of two fixed position goes to its axial accurately 0.

01 Mm, ensure two pedestal locate reliably. Neck of crankshaft main shaft and brace sell the parallelism between the demand is very high, error with 0.

01 Mm/m is an unit metric, detect the treatment precision of each component of the tool, must control strictly inside design requirement limits, have microtherm ageing treatment by the requirement. Attached drawing 4, detect the program is assembled above all and desired result detects tool, had assembled by attached drawing detect tool, place the pedestal that installed the roller that prop up go up in vertical axis of standard desired result, sell fixed good slip ring with oriented fixed position, make its lie slippery lever (or in fixed position slippery lever) radial position. In strut bar of slip ring jacket. Dial gauge is assembled to wear on strut bar with dial gauge, the direction of normal of cross section of vertical axis of standard desired result that asks the measuring staff of dial gauge is contacted at the place that measure a head. Pushing slip ring gently to be in slippery lever (or fixed position slippery lever) slide slowly, examination desired result is measured on, ensure its are achieved measure precision to ask next, crankshaft (or some shaft part) the brace that go up is sold (or some brace is sold) rotate to hang down in same lead with main shaft neck up the position, assemble desired result to detect well the tool is placed in crankshaft (or some shaft part) on main shaft neck, adjust dial gauge to wear appropriately with dial gauge, assure the measuring staff of dial gauge, the brace that contacts at the place that measure a head sells way of cross section normal. When measuring, pushing slip ring gently to be in slippery lever (or fixed position slippery lever) ) go up to slide slowly, the reading that passes dial gauge changes but the spot is various the ground measures this crankshaft accurately (or some shaft part) line of center of main shaft neck and brace are sold (or some brace is sold) the ask parallelism alignment error of central line, for accurate detect crankshaft provides accurate data quickly. 5, applied effect H22, compressor of 6M50 hydrogen nitrogen, in moving, ever happened to cover with tiles because of connecting rod is big for many times invalidation, bring about brace to sell wear away badly. Manual method is used to repair brace to sell commonly when maintenance, measuring, file is cut, in the repairman foreword such as abrade, polish, gradienter of type of commonly used casing or optics close like gradienter, instant, detect for many times brace is sold reach photograph adjacent neck of two main shaft is spent in the level of at least 8 direction, so that assure brace,sell relative to the parallelism at main shaft neck. But columnar face is uneven outside be being sold because of brace, gradienter of the type that use frame detects the brace that go out sells a level to spend not accurate, cause the treatment position that repairs brace of personnel mistake delimit to sell, the influence repairs quality and plan, appear even corresponding connecting rod is big tile is in aircrew is no load test-drive phase namely invalidation. Convert after attached drawing place shows a tool to detect, brace sells parallelism alignment error of neck of opposite main shaft detect precision rises substantially, had not appeared to repair brace of personnel miscarriage of justice to sell the circumstance that machines place to repair plan to accelerate, quality is able to assure, detect with this law the brace of repair is sold reach corresponding connecting rod is big bearing to all can run 8000h above normally.
