摘 要


搖臂軸是柴油機支撐氣門搖臂，內(nèi)有油道的輸送潤滑油。搖臂軸支座是用于將搖臂軸固定在柴油機上，為了加強搖臂軸支座的定位，在其底部螺栓孔處有定位凸臺，使其定位在缸蓋螺栓孔內(nèi)。
零件的材料為HT200，應(yīng)采用鑄件，由于零件為中批生產(chǎn)，其輪廓尺寸也不大。故可采用鑄造成型。這對提高生產(chǎn)率，保證加工質(zhì)量也是有利的。
為了提高勞動生產(chǎn)率，保證加工質(zhì)量，降低勞動強度，需設(shè)計專用夾具。由于本零件在組合機床上經(jīng)過多數(shù)工序操作，為其設(shè)計專用夾具可大大縮短加工各工序間的時間間隔，提高勞動生產(chǎn)率。

ABSTRACT


The valve refers to entering the valve and exhaust valve of the cylinder. Enter valve connect inlet manifold whether engine used for , suck , mix angry entry of (or fresh air ) directly; The exhaust valve is connecting the exhaust manifold, it is the engine that discharges the export which burns the waste gas .
Engine each valve that cylinder have count, have two valve, 3 valves, several kinds of four valves and five valves .
It is a important factor to determine performance quality of the engine to enter the efficiency of exhausting, the pace of reciprocating motion of the piston is very fast when the engine runs well, transfer to in 3000 / rotational speed for minute lay engine finish every one enter angry or exhaust the time of the journey is 0.04 seconds, if you want to suck into or discharge the valid area that more gas will increase into , exhaust within such short time. Then some engines adopt many valve technology.
The rocker shaft is that the diesel engine supports the valve rocker, there is transport lubricating oil of the oil passageway inside. Rocker shaft prop up flat used for , fix rocker shaft on diesel engine , for strengthen rocker shaft localization to prop up flat, orient the protruding platform in its bottom of bolt hole places , make it make a reservation in the jar cover the bolt hole.
