Engine Crankshaft flywheel coetus components
Primo, crankshaft
Crankshaft is one of the most important parts of the engine, its function is to withstand the gas pressure from the piston connecting rod group into the torque of the crankshaft and external output, in addition, the crankshaft is also used to drive the engine's valve mechanism and other auxiliary devices (such as generators, fans, water pumps, power steering pumps, balance shaft mechanism, etc.)
Crankshaft Flywheel Group 1- Pulley; 2- crankshaft sincere dente balteus rotam; 3- crankshaft Sprockel; 4- crankshaft; 5. Crankshaft principalis portantes (top); 6 flywheel; 7- celeritate sensorem signo generans; VIII, 11- percussit pad; 9. Crankshaft principalis portantes (imo); 10- crankshaft principalis afferentem operimentum.
When the crankshaft works, it must withstand periodic changes in gas pressure, reciprocating inertial force and centrifugal force, as well as their torque and bending moment under high-speed operation, easy to bend and twist deformation, therefore, the crankshaft should have enough strength and stiffness, good wear resistance and good balance. In crankshaft est plerumque factum ex medium ipsum muro ferro et Journal superficies agitur ab altus-frequency extinguendo aut nitriding. Shanghai Mortis engine crundum, quod factum est summus qualis medium ipsum ferro mori cudere. In Audi JW et Yuchai Yc6105QC engines fiunt humilis sumptus, summus viribus rara terra Ductile ferrum bonum gerunt resistentia.
I. structuram de crankshaft
Crankshaft est plerumque composito fronte finem, pelagus pelagus cervix, crank, a counterweight, a connectens virga Journal et tergo finem. A crank est composito ex connectens virga Journal et sinistram et ius principalem journals. Numerus crank de crankshaft pendeat numero et Ordinatio cylindrici. Et crankshaft de uno cylindrici engine habet tantum unum crank; Numerum crank crankshaft in linea engine aequalis numero cylindri Numerus cranks in crankshaft V engine aequalis dimidiam numerum cylinderum. In fronte-finem hastile de crankshaft est instructa cum trochleis, leo calces, etc., quod est ad eiciam aqua sentinam et valvae mechanism. Et fusum collum in crankshaft est installed in pelagus ferre sedes cylindri corporis et adhibetur ad auxilium in crankshaft. Et connectens virga Journal est ad install in connectens virga, et crank connectit pelagus hastile journal cum connectens virga Journal. Ut statera centrifuga vi cum crankshaft gyrari, a statera obstructionum est provisum in crankshaft. A connectens LABIUM provisum est a tergo finem in crankshaft ad coniungere ad flywheel ad crankshaft per seras. Ad lubricate ad connectens virga Journal, Lubricating transitus est a principalis hastile Journal ad connectens virga Journal. Integralis crundum est simplex in structuram, lux in pondere et certa in operatione, et plerumque adoptat plane plane, quae late in medium et parvum machinas.
II. Layout principium crank
Forma crankshaft et relativus situ singulis crank maxime dependet numero cylindricibus, Ordinatio cylindricis et operationem ordine cuiusque cylindri. Disputatio engine opus sequentia praecepta sequi quantum fieri potest:
Fac duas cylindricos continua operis quatenus seorsum fieri potest ad redigendum onus pelagus afferentem, et vitare eventum duorum pertinet valvulae ostium simul in attractio processus, et phaenomenon in engine.
(I) Quod opus intervallum angulum cuiusque cylindri debet esse aequalis ad faciliorem lenis operationem de engine. In crankshaft angle quo engine complet opus cycle, singulis cylindri debet operari semel. Nam quattuor-ictu engine cum cylindrici numero ego, opus spatium angulum est DCCXX ° / i. Id est, omnis DCCXX ° / ego de crankshaft debet habere cylindri ad opus ut machinam decurrit aequaliter.
(II) si est a V-genus engine, sinistram et dextrum columnas cylindrici alternas opus.
III. Commune multi-cylindrici engra crank dispositio et operantes ordinem
Ordinatio crankshaft crank in linea quattuor ictu engine. Opus Intervallum in-linea quattuor-cylinder quattuor-ictu engine est DCCXX ° / IV = CLXXX °, quatuor crank sunt disposita in eodem plano, et engine opus sequence (vel ignitionem serie) is 1-3-4-2 et 1-2-4-3. Quod opus cycle impellit fabrica vulgo usus habet unum-postesque semi-circularis iaculat codex cum anti-friction metallum iacuit, crankshaft principalis ferre cum flacquing et per cornichaft habet tres formas. Et percussit pad est semi-anulum ferro sheet cum anti-friction stagnum layer in extra, quod est installed in sulcus corporis vel principalis afferentem operimentum. Ut ne in gyrationis et percussit pad, et percussit pad habet tumultuosi adhæsit in sulcus. Quidam falces pads uti IV formare duo positivae circulari terminum, et quaedam usus II pieces of fines. Latus anti-frictio metallo faciem ad crankshaft.
