JRTRXF57減(jian)速(su)器(qi)型(xing)號大全齒(chi)輪(lun)減(jian)速(su)機設(she)(she)計(ji)常見問(wen)題剖析。在(zai)齒(chi)輪(lun)減(jian)速(su)機的(de)(de)設(she)(she)計(ji)中，有部分(fen)零件(jian)(jian)(jian)(jian)(jian)可由強(qiang)度(du)(du)(du)條件(jian)(jian)(jian)(jian)(jian)或剛(gang)度(du)(du)(du)條件(jian)(jian)(jian)(jian)(jian)確(que)定零件(jian)(jian)(jian)(jian)(jian)的(de)(de)基本尺(chi)寸(cun)，然后通過草(cao)圖設(she)(she)計(ji)決定其(qi)具(ju)體結構和(he)(he)尺(chi)寸(cun)（如(ru)齒(chi)輪(lun)）；而另有部分(fen)零件(jian)(jian)(jian)(jian)(jian)（如(ru)軸）則需(xu)要先(xian)經初步(bu)計(ji)算和(he)(he)繪(hui)制(zhi)草(cao)圖，得出初步(bu)符合設(she)(she)計(ji)條件(jian)(jian)(jian)(jian)(jian)的(de)(de)基本結構尺(chi)寸(cun)，然后進行(xing)必要的(de)(de)校核(he)計(ji)算，根據計(ji)算結果，再對結構和(he)(he)尺(chi)寸(cun)進行(xing)修改，甚(shen)至反復多次修改。零件(jian)(jian)(jian)(jian)(jian)尺(chi)寸(cun)不可能完全由理(li)論(lun)計(ji)算確(que)定，而是要綜合考(kao)慮齒(chi)輪(lun)減(jian)速(su)電機結構和(he)(he)其(qi)它各方面(mian)(mian)的(de)(de)要求才能決定。零件(jian)(jian)(jian)(jian)(jian)的(de)(de)設(she)(she)計(ji)過程(cheng)(cheng)是個綜合考(kao)慮強(qiang)度(du)(du)(du)、結構、裝配和(he)(he)工藝(yi)等因素(su)的(de)(de)過程(cheng)(cheng)，理(li)論(lun)計(ji)算只是為合理(li)確(que)定零件(jian)(jian)(jian)(jian)(jian)尺(chi)寸(cun)提供了某些方面(mian)(mian)（如(ru)強(qiang)度(du)(du)(du)、剛(gang)度(du)(du)(du)）的(de)(de)依(yi)據。此(ci)外，齒(chi)輪(lun)減(jian)速(su)機的(de)(de)設(she)(she)計(ji)時還要盡量使用(yong)標準件(jian)(jian)(jian)(jian)(jian)。
