RV-E robot dedicated reducer

RV drive is a new type of transmission, which is developed on the basis of the traditional pin-type planetary transmission, not only to overcome the shortcomings of the general pin-driven, but also because of its small size, light weight, a large transmission ratio, life Long, accurate and stable, high efficiency, smooth transmission and a series of advantages. Increasing attention by both at home and abroad. RV reducer is composed of cycloid pin and planetary carrier with its small size, strong impact resistance, large torque, high positioning accuracy, small vibration, large reduction gear ratio and many other advantages are widely used in industrial robots, machine tools, medical testing Equipment, satellite receiving systems and other fields. It is much higher than the harmonic drive commonly used in robots fatigue strength, stiffness and life expectancy, and hysteresis accuracy and stability, unlike harmonic drive with the use of time as the movement accuracy will be significantly reduced, so many countries in the world High-precision robot drive to use more RV reducer, therefore, the kind of RV reducer in the advanced robot drive has gradually replaced the harmonic reducer trend

l)傳動比范圍大;
(2)扭轉(zhuǎn)剛度大,輸出機構(gòu)即為兩端支承的行星架,用行星架左端的剛性大圓盤輸出,大圓盤與工作機構(gòu)用螺栓聯(lián)結(jié),其扭轉(zhuǎn)剛度遠大于一般擺線針輪行星減速器的輸出機構(gòu)。在額定轉(zhuǎn)矩下,彈性回差??;
(3)只要設(shè)計合理,制造裝配精度保證,就可獲得高精度和小間隙回差;
(4)傳動效率高;

(5)傳遞同樣轉(zhuǎn)矩與功率時的體積小(或者說單位體積的承載能力大),RV減速器由于第一級用了三個行星輪,特別是第二級,擺線針輪為硬齒面多齒嚙合,這本身就決定了它可以用小的體積傳遞大的轉(zhuǎn)矩,又加上在結(jié)構(gòu)設(shè)計中,讓傳動機構(gòu)置于行星架的支承主軸承內(nèi),使軸向尺寸大大縮小,所有上述因素使傳動總體積大為減小。


精密減速機幾乎被日本壟斷,他們NB在哪些方面?

精密減速機,是一種動力傳達機構(gòu),其利用齒輪的速度轉(zhuǎn)換器,將電機的回轉(zhuǎn)數(shù)減速到所要的回轉(zhuǎn)數(shù),并得到較大轉(zhuǎn)矩的裝置。

精密減速機幾乎被日本壟斷,他們NB在哪些方面?

精密減速機是一種相對精密的機械,使用它的目的是降低轉(zhuǎn)速,增加轉(zhuǎn)矩。

精密減速機幾乎被日本壟斷,他們NB在哪些方面?

精密減速機根據(jù)精度可分為標準精度和高精度;根據(jù)用途可分為軍用和民用;根據(jù)運行的環(huán)境可分為標準環(huán)境、低溫環(huán)境、清潔室環(huán)境和真空環(huán)境。
