齒輪齒條穿洞中(zhong)往(wang)往(wang)存(cun)在齒(chi)(chi)側(ce)間隙，為了驅動(dong)機(ji)構(gou)(gou)的雙向(xiang)(xiang)驅動(dong)精(jing)度(du)必須消除間隙。設計了一種(zhong)通過(guo)絲杠螺(luo)母(mu)機(ji)構(gou)(gou)軸(zhou)向(xiang)(xiang)的相(xiang)(xiang)對(dui)位移來帶(dai)動(dong)與齒(chi)(chi)輪(lun)相(xiang)(xiang)嚙合的兩個(ge)齒(chi)(chi)條，使(shi)兩齒(chi)(chi)條出現一個(ge)軸(zhou)向(xiang)(xiang)的相(xiang)(xiang)對(dui)位移，即(ji)兩齒(chi)(chi)條錯齒(chi)(chi)，使(shi)當(dang)量齒(chi)(chi)厚增大，從而自動(dong)消除齒(chi)(chi)側(ce)間隙的機(ji)構(gou)(gou)。該(gai)機(ji)構(gou)(gou)已成功應用于齒(chi)(chi)輪(lun)齒(chi)(chi)條驅動(dong)的回轉工(gong)作臺，結構(gou)(gou)簡單、驅動(dong)精(jing)度(du)高(gao)、效果顯著。
