減速機在原動機和工作機或執(zhí)行機構之間起匹配轉(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.

安裝減速機時，應重視傳動中心軸線對中，其誤差不得大于所用聯(lián)軸器的使用補償量。對中良好能延長使用壽命，并獲得理想的傳動效率.

When installing the reducer, we should pay more attention to the axis of the transmission center, and the error should not be greater than the use compensation of the couplings used. It can prolong the service life and obtain the ideal transmission efficiency for the good.

通常齒輪減速機已廣泛應用于冶金、礦山、起重、運輸、水泥、建筑、化工、紡織、印染、制藥、等領域。但在這種齒輪減速機的使用有一定的限制,所以,讓我們了解下使用時需要注意什么。

1、高速旋轉(zhuǎn)不超過1500 r / min。齒輪減速器。

2、齒輪圓周速度不超過20 m / s。

Usually gear reducer has been widely used in metallurgy, mining, lifting, transportation, cement, ctruction, chemical, textile, printing and dyeing, pharmaceutical, and other fields. But there are some restricti on the use of this gear reducer, so let us know what to pay attention to when using it.

1. The high speed rotation does not exceed 1500 R / min. Gear reducer.

2, the circumferential speed of the gear is not more than 20 m / S.

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.
