減速機在原動機和工作機或執(zhí)行機構(gòu)之間起匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的作用,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。它的種類繁多,型號各異,不同種類有不同的用途。
The reducer plays the role of matching speed and transmission torque between the original motive and the working machine or the actuator. It is a relatively precise machine. The pure of using it is to reduce the speed and increase the torque. It has a wide variety of types and different types, and different types have different uses.
在減速機家族中,行星減速機以其體積小,減速范圍廣,精度高等諸多有點,而被應(yīng)用于伺服、步進、直流等傳動系統(tǒng)中。其作用就是在保證精密傳動下,主要被用來降低轉(zhuǎn)速增大扭矩和降低負(fù)載/電機的轉(zhuǎn)動慣量比。
In reducer family, planetary reducer is applied to servo, step and DC transmission systems because of its small volume, wide range of deceleration and high accuracy. Its role is to ensure the precision drive, mainly used to reduce the rotational speed to increase the torque and reduce the load / motor inertia ratio.
減速機內(nèi)部齒輪齒形修整(修緣和修根)和齒頂?shù)菇?將齒頂?shù)凝X形切削成比正確的漸開曲線略呈凸形。當(dāng)齒輪齒面受外力產(chǎn)生變形時,可以避免對與之嚙合的齒輪產(chǎn)生干涉,并且可以降低噪音,延長齒輪壽命。
The internal gear of the reducer is trimmed (trim and trim) and tooth top chamfering to make the tooth shape of the tooth top convex than the correct involute curve. When the gear tooth surface is deformed by external force, it can avoid interference to the gears engaged with it, and can reduce noise and prolong the service life of gears.
對減速機箱體進行共振測試,找出共振位 置,增加適當(dāng)?shù)慕顥l(板),可以提高箱體的剛度,減少箱體的振動,實現(xiàn)降噪。多級傳動時要求瞬時傳動比的變化盡量小,以保證傳動平穩(wěn),沖擊及振動小,噪聲低。
By testing the resonance of the reducer box, finding out the resonance and adding appropriate ribs (plates), the stiffness of the box can be increased, the vibration of the box can be reduced and the noise can be reduced. In multistage transmission, the change of instantaneous transmission ratio should be as small as to ensure stable transmission, low impact and vibration, and low noise.
