減速機一般用于低轉(zhuǎn)速大扭矩的傳動設(shè)備，把電動機、內(nèi)燃機或其它高速運轉(zhuǎn)的動力通過減速機的輸入軸上的齒數(shù)少的齒輪嚙合輸出軸上的大齒輪來達到減速的目的，普通的減速機也會有幾對相同原理齒輪達到理想的減速，大小齒輪的齒數(shù)之比，就是傳動比。

Reducer is generally used in driving equipment of low speed high torque, large gear gear output shaft power motor, internal combustion engine or other high speed running through the reducer input shaft less number of teeth on the reducer to achieve the pure of general reducer will have several pairs of the same principle to achieve the ideal effect of gear reducer. The size of the number of teeth of the gear ratio, the transmission ratio is.

減速機作為機械傳動的組成部分，其重要意義不言而喻。減速機行業(yè)屬于國民經(jīng)濟發(fā)展的基礎(chǔ)行業(yè)，從生活家電到汽車飛機、從生產(chǎn)工具到建筑機械，幾乎所有的機械傳動系統(tǒng)中都需要使用到減速機。隨著市場需求的不斷深化，讓減速機市場得到快速發(fā)展，當然減速機的品種也在不斷豐富。Thesizeofthenumberofteethofthegearratio,thetransmissionratiois。

As an important part of mechanical transmission, the speed reducer is self-evident. The reducer industry is the basic industry of national economic development, from living appliances to automobile aircraft, from production tools to ctruction machinery, almost all of the mechanical transmission systems need to be used to the reducer. With the deepening of market demand, the reducer market has been developing rapidly. Of course, the variety of reducer is also continuously enriched.

對減速機箱體進行共振測試，找出共振位 置，增加適當?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.
