可(ke)實現單(dan)向離合的(de)(de)(de)RV25蝸(gua)輪(lun)蝸(gua)桿減(jian)速(su)(su)機(ji)設計(ji)。在蝸(gua)輪(lun)蝸(gua)桿減(jian)速(su)(su)機(ji)的(de)(de)(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)裝置中，其(qi)原(yuan)理是動(dong)(dong)(dong)(dong)(dong)力(li)(li)從蝸(gua)桿端輸(shu)(shu)(shu)(shu)入，蝸(gua)桿帶動(dong)(dong)(dong)(dong)(dong)蝸(gua)輪(lun)實現大減(jian)速(su)(su)比傳(chuan)動(dong)(dong)(dong)(dong)(dong)，蝸(gua)輪(lun)帶動(dong)(dong)(dong)(dong)(dong)輸(shu)(shu)(shu)(shu)出軸轉動(dong)(dong)(dong)(dong)(dong)作為輸(shu)(shu)(shu)(shu)出。但由于RV減(jian)速(su)(su)機(ji)蝸(gua)輪(lun)蝸(gua)桿的(de)(de)(de)自鎖(suo)作用，當(dang)蝸(gua)輪(lun)蝸(gua)桿無動(dong)(dong)(dong)(dong)(dong)力(li)(li)輸(shu)(shu)(shu)(shu)入時(shi)，輸(shu)(shu)(shu)(shu)出軸被鎖(suo)死，輸(shu)(shu)(shu)(shu)出軸端難(nan)(nan)以自由轉動(dong)(dong)(dong)(dong)(dong)，蝸(gua)輪(lun)蝸(gua)桿減(jian)速(su)(su)機(ji)應用在茶葉揉捻機(ji)上時(shi)，在機(ji)器的(de)(de)(de)使用過程(cheng)中，當(dang)電(dian)機(ji)動(dong)(dong)(dong)(dong)(dong)力(li)(li)停(ting)止(zhi)時(shi)，需要手動(dong)(dong)(dong)(dong)(dong)推動(dong)(dong)(dong)(dong)(dong)揉桶，但是RV減(jian)速(su)(su)機(ji)構由于其(qi)自鎖(suo)結(jie)構的(de)(de)(de)特性，就會(hui)出現輸(shu)(shu)(shu)(shu)出端難(nan)(nan)以手動(dong)(dong)(dong)(dong)(dong)轉動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)問題。
