Abstract
A vernier type crankshaft trimming moment detector mainly comprises a measuring bar, a bush, a flat key, a main measuring block, a left vernier, a right vernier, a support, etc. The measuring bar and the main measuring block of the detector are used to preliminarily determine crankshaft static balance moments of an S195 diesel engine, and through movement of the left vernier and the right vernier on the measuring bar, the crankshaft static balance moments of the S195 diesel engine is accurately obtained. The detector can conveniently measure the crankshaft static balance moments of the S195 diesel engine, and improves measurement speed and accuracy of the crankshaft static balance moments of the S195 diesel engine.
Description
Technical field
The technology of the present invention relates to the detector that a kind of energy is convenient, measure rapidly, exactly S195 crankshaft of diesel engine Lopsided Moment.
Background technology
S195 crankshaft of diesel engine Lopsided Moment is an important parameter of S195 crankshaft of diesel engine, its size directly has influence on power, the oil consumption of S195 diesel engine, affect especially a main factor of S195 diesel engine vibrations, on there being direct impact the serviceable life of S195 diesel engine.In order to save the energy, improve the power of S195 diesel engine, S195 diesel engine can be worked reposefully, extend their life-span, we must know S195 crankshaft of diesel engine Lopsided Moment.S195 crankshaft of diesel engine manufacturing enterprise seeks to measure how quickly and accurately its Lopsided Moment for many years always for this reason.The present invention can facilitate, measure rapidly, exactly S195 crankshaft of diesel engine Lopsided Moment.
Summary of the invention
The present invention is directed to the measurement problem of S195 diesel engine Lopsided Moment, the detector that can facilitate, measure rapidly S195 crankshaft of diesel engine Lopsided Moment is provided.
The technical solution used in the present invention is: mainly sounding rod, measurement circle, flat key, main measurement piece, left vernier, right vernier, support etc., consist of.S195 crankshaft of diesel engine is placed on support, loads onto and measure circle on S195 crankshaft of diesel engine, mobile left and right vernier, can facilitate, promptly measure the Lopsided Moment of S195 crankshaft of diesel engine.Main measurement piece is fixed on one end of sounding rod, and left and right vernier can move freely on sounding rod.Support is a way of contact when propping S195 crankshaft of diesel engine.By the distance of main measurement piece, left vernier, right vernier and axis, more easily obtain S195 crankshaft of diesel engine Lopsided Moment value.
The invention has the beneficial effects as follows: measure conveniently, rapidly, exactly S195 crankshaft of diesel engine Lopsided Moment.

Embodiment
The designing requirement of S195 diesel engine Lopsided Moment is 0.78 ± 0.005Nm, for ease of calculate and measurement, it is converted into 7959.18 ± 50g (power) cm.When carrying out the measurement of S195 diesel engine Lopsided Moment, S195 crankshaft of diesel engine (in Fig. 1,2 1) is placed on support (in Fig. 1,2 7), in order to reduce S195 crankshaft of diesel engine (in Fig. 1,2 1) and support (in Fig. 1,2 7) friction, improve measuring accuracy, support (in Fig. 1,2 7) and S195 crankshaft of diesel engine (in Fig. 1,2 1) adopt to put and contact; Then measuring, on the ∮ 30 gear diameters of axle of circle (in Fig. 1,2 4) and S195 crankshaft of diesel engine (in Fig. 1,2 1), adopt flat key (in Fig. 1,2 3) to be connected, as Fig. 1 places, left vernier (in Fig. 1,2 2), right vernier (in Fig. 1,2 5) are moved to zero position simultaneously.The quality of main measurement piece (in Fig. 1,2 6) is 468.187 grams, the quality of left vernier (in Fig. 1,2 2), right vernier (in Fig. 1,2 5) is 50 grams, main measurement piece (in Fig. 1,2 6) center is 17 centimetres to the distance of crankshaft center, and can obtain moment is 468.187 * 17=7959.18 ± 50g (power) cm; When main measurement piece (in Fig. 1,2 6) end is higher than the other end, mobile right vernier (in Fig. 1,2 5), makes sounding rod (in Fig. 1,2 8) level, and reading is overgauge; When main measurement piece (in Fig. 1,2 6) end is lower than the other end, mobile left vernier (in Fig. 1,2 2), makes sounding rod (in Fig. 1,2 8) level, and reading is minus deviation.The right and left at sounding rod (in Fig. 1,2 8) all has ten large lattice, and each large lattice is 1 centimetre, again large lattice is divided into 10 little lattice, and each little lattice is 0.1 centimetre.The little lattice of the every movement one of vernier all produce the moment of 5g (power) cm.So when measuring moment, read the mobile little lattice number of left vernier (in Fig. 1,2 2), right vernier (in Fig. 1,2 5), just know corresponding moment, then add main measurement piece (in Fig. 1,2 6) moment, rapidly, accurately drawn S195 crankshaft of diesel engine Lopsided Moment.
Example 1: left vernier reading is 0, right vernier reading is 1.5, crankshaft static balance moment is 7959.18+5 * 15g (power) cm=7959.18+75g (power) cm.
