<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">摩托车传动链条分为普通链和<span style="color: black;">无声链，普通链又分为单排链和双排链。骑式车链条传动，<span style="color: black;">重点</span>采用普通链中的单排链。单排链按结构分为滚子链、套筒链、密封链3种。单排链由内链节、内链板、套筒、个滚子<span style="color: black;">构成</span>。外链节由外链板、销轴和连接链节<span style="color: black;">构成</span>。<span style="color: black;">非常多</span>外链节相间连接成一长串，再用一个活链节（见图4）连接两端<span style="color: black;">作为</span>一个环形。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">主动链轮。主动链轮的齿数对<span style="color: black;">传动的<span style="color: black;">安稳</span>性和链条的<span style="color: black;">运用</span>寿命影响很大。在传动链条节距不变时，增大主动链轮齿数能<span style="color: black;">增多</span>传递功率。但主动链轮齿数<span style="color: black;">太多</span>、直径过大，从动链轮齿数不变或<span style="color: black;">增多</span>从动齿轮的齿数，会<span style="color: black;">显现</span>爬坡度下降、爬坡无力、动力性不足、链条跳齿和掉链等现象，影响链条传动的<span style="color: black;">安稳</span>性。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">链条的<span style="color: black;">调节</span>。松开后轮轴螺<span style="color: black;">母、锁紧螺母，左、右方向转动后</span><span style="color: black;">轮轴左、右侧链条<span style="color: black;">调节</span>器调节螺</span><span style="color: black;">母，后轮前后移动使链条松紧度<span style="color: black;">出现</span>变化。链条松紧度<span style="color: black;">调节</span>合适后，<span style="color: black;">上下</span>侧链条调节器刻线应与后摇臂上的刻线相对应，链条上下移动距离在10～20 mm，前后轮在同一条直线上，拧紧锁紧螺母和后轮轴螺母。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">链条过脏，应拆开链节头，从<span style="color: black;">链轮上取下链条，用煤油或汽油浸泡，用毛刷清洗，晾干油迹后，应加注适量润滑油。链条传动<span style="color: black;">安装</span>故障检修。链条传动<span style="color: black;">平常</span>故障有，运转噪声大、掉链、链条时紧松链条松紧度<span style="color: black;">没法</span><span style="color: black;">调节</span>、车行驶前后车轮不在一条直线上、后轮<span style="color: black;">上下</span>摇摆；起步、变档、加油门时，后传动反应迟钝、<span style="color: black;">显现</span>运转冲击噪声；后制动踏板自由行程过大等。</span></p>
