RV減速機是新興起的一種高減速比的傳動系統,它是在傳統擺線針輪減速機(Cycloid drive)的基礎上發展出來的,不僅克服了一般擺線針輪減速機的缺點,而且因為具有體積小、重量輕、減速比範圍大、壽命長、精度保持穩定、效率高、傳動平穩等一系列優點。日益受到國內外的廣泛關注。RV減速機是由擺線針輪減速機和行星齒輪系所組成,以其體積小、抗衝擊力強、扭矩大、定位精度高、振動小、以及減速比大等諸多優點,被廣泛應用於工業機器人、機床、醫療檢測設備、以及衛星接收系統等領域。它較機器人中常用的諧波傳動(Harmonic drive)具有高得多的疲勞強度、剛度和壽命,而且誤差精度穩定,不像諧波傳動那樣隨著使用時間增長運動精度就會顯著降低,故世界上許多國家高精度機器人之傳動系統多採用RV減速機,在先進機器人傳動系統中有逐漸取代諧波減速機的發展趨勢。
RV reducer is a new type transmission system with high reduction, which is developed on the basis of the traditional Cycloid Drive. RV reducer has the advantages of mall size, light weight, high reduction ratio, long life, high precision, high efficiency, smooth transmission. And, it also overcomes the shortcomings of Cycloid Drive. RV reducer is the combination of Cycloid Drive and planetary gear train. So as time goes, the accuracy of harmonic drive will be reduced. So, due to the above advantages, RV reducer is widely used in many industrial robots to replace the transmission system of harmonic drive.
