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.

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。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(dāng)然減速機的品種也在不斷豐富。

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.

減速機內(nèi)部齒輪的齒距和壓力角 小齒距能保證有較多的輪齒同時接觸，齒輪重疊增多，減少單個齒輪撓曲，降低傳動噪聲，提高傳動精度。較小的壓力角由于齒輪接觸角和橫六角空心磚模具向重疊比都比較大，因此運轉(zhuǎn)噪聲小、精度高。

The tooth distance of the gear in the reducer and the small pitch of the pressure angle can ensure that there are more teeth at the same time, the overlap of the gear is increased, the deflection of the single gear is reduced, the transmission noise is reduced, and the transmission precision is improved. The smaller pressure angle is due to the larger contact ratio between the gear contact angle and the six corners of the hollow brick mold, so the running noise is small and the accuracy is high.

減速機動力源運轉(zhuǎn)速度 根據(jù)在不同轉(zhuǎn)速條件下對減速機的試驗表明，隨著減速機輸入轉(zhuǎn)速的增加，噪聲也將增大。 

The experimental study on the structural form of the reducer box shows that the cylindrical box is advantageous to vibration reduction. Under the same other conditi, the noise level of the cylindrical box is 5 dB lower than that of other types of box on average.
