10、t;p>　　通過對側(cè)滑試驗(yàn)臺的檢定，往往會發(fā)現(xiàn)示值超差，造成的原因基本上有兩個方面：一是機(jī)械方面的原因，主要是滑動板、聯(lián)動機(jī)構(gòu)及回零機(jī)構(gòu)機(jī)件磨損，間隙增大所致，二是電氣方面的原因，測試儀表或傳感器內(nèi)的電子器件老化、零點(diǎn)漂移、阻值變化或元件損壞所致。調(diào)整方法如下：</p><p><b>　　1．機(jī)械方面的檢查</b></p><p>　　(1) 用彈簧拉力計，檢

11、查拉力和回零情況。</p><p>　　拉力的大小和回零的好壞取決于兩個方面的原因，一是潤滑系統(tǒng)的好壞，二是回零彈簧的松緊。針對第一方面的原因，應(yīng)采取的措施是：檢查滑板下面的滾輪和導(dǎo)軌并加以清洗或更換，檢查兩塊滑板中間的導(dǎo)向軸承及其他軸承并加以清洗或更換。針對第二方面的原因，應(yīng)采取的措施是：在保證回零誤差不超標(biāo)的前提下調(diào)松“回零彈簧”。由于結(jié)構(gòu)上的原因，拉力的大小和回零的好壞是一對矛盾，調(diào)緊“回零彈簧”則回零好，

12、但是拉力變大，調(diào)松“回零彈簧”則拉力小，但是回零不好。所以在調(diào)整“回零彈簧”時一定要兼顧拉力和回零兩個指標(biāo)。</p><p>　　(2) 同步性的檢查與調(diào)整</p><p>　　用兩塊百分表檢查。每塊滑板各安裝一個百分表，調(diào)零完成后推主動板（裝有傳感器的一側(cè)），檢查兩塊百分表的示值，就可讀取同步性的好壞。在只有一塊百分表時，將百分表裝在從動板上，與傳感器直接相聯(lián)的主動板位移量可通過檢測儀表

13、來顯示。同步性誤差產(chǎn)生的原因有以下兩個方面，一方面是滑板導(dǎo)向機(jī)構(gòu)的軸承間隙造成的，其次是聯(lián)動機(jī)構(gòu)同步杠桿不等距造成的。其表現(xiàn)形式也不相同，軸承間隙造成的不同步一般是兩塊滑板相差一個常數(shù)，跟滑板推動的長度無關(guān)，而聯(lián)動機(jī)構(gòu)同步杠桿造成的誤差是一個變數(shù)，誤差會隨著滑板移動的增加而增大。如果從動板的數(shù)值較大，說明從動板杠桿距中心軸較遠(yuǎn)，如果從動板的數(shù)值較小，說明從動板杠桿距中心軸較近，調(diào)整任意一個滑板的都可以，只是注意調(diào)整的方向。</p&
