平衡重概述

    平衡重有兩種
，一種是與曲軸製成一體；另(ling)一(yi)種(zhong)是(shi)製(zhi)成(cheng)單(dan)獨(du)的(de)，再(zai)用(yong)螺(luo)釘(ding)固(gu)定(ding)在(zai)曲(qu)柄(bing)上(shang)。後(hou)一(yi)種(zhong)叫(jiao)做(zuo)裝(zhuang)配(pei)式(shi)平(ping)衡(heng)重(zhong)
，發(fa)動(dong)機(ji)一(yi)般(ban)采(cai)用(yong)一(yi)體(ti)式(shi)的(de)平(ping)衡(heng)重(zhong)。加(jia)平(ping)衡(heng)重(zhong)會(hui)導(dao)致(zhi)曲(qu)軸(zhou)質(zhi)量(liang)增(zeng)加(jia)和(he)材(cai)料(liao)消(xiao)耗(hao)增(zeng)加(jia)，鍛(duan)造(zao)工(gong)藝(yi)複(fu)雜(za)。因(yin)而(er)

，曲(qu)軸(zhou)是(shi)否(fou)加(jia)平(ping)衡(heng)重(zhong)

，要(yao)視(shi)具(ju)體(ti)情(qing)況(kuang)而(er)定(ding)。

    平衡重的類型：有you的de平ping衡heng重zhong與yu曲qu軸zhou連lian為wei一yi體ti，也ye就jiu是shi與yu曲qu柄bing模mo鍛duan為wei一yi體ti，設she置zhi在zai曲qu柄bing前qian端duan。也ye有you的de平ping衡heng重zhong是shi單dan獨du設she置zhi一yi平ping衡heng塊kuai

，用yong螺luo栓shuan與yu曲qu柄bing前qian端duan麵mian連lian接jie。對dui稱cheng布bu置zhi的de曲qu拐guai離li心xin力li、慣(guan)性(xing)力(li)及(ji)其(qi)產(chan)生(sheng)的(de)力(li)矩(ju)是(shi)平(ping)衡(heng)的(de)。如(ru)四(si)缸(gang)發(fa)動(dong)機(ji)的(de)曲(qu)軸(zhou)，在(zai)慣(guan)性(xing)力(li)影(ying)響(xiang)下(xia)，前(qian)相(xiang)鄰(lin)的(de)兩(liang)個(ge)連(lian)杆(gan)軸(zhou)頸(jing)產(chan)生(sheng)的(de)彎(wan)矩(ju)與(yu)後(hou)相(xiang)鄰(lin)的(de)兩(liang)個(ge)連(lian)杆(gan)軸(zhou)頸(jing)產(chan)生(sheng)的(de)彎(wan)矩(ju)方(fang)向(xiang)相(xiang)反(fan)。因(yin)此(ci),zhenggequzhou
