安裝前確認(rèn)電機(jī)和減速機(jī)是否完好無損，并且嚴(yán)格檢查電機(jī)與減速機(jī)相連接的各部位尺寸是否匹配，這里是電機(jī)的定位凸臺、輸入軸與減速機(jī)凹槽等尺寸及配合公差。

Before installation, confirm whether the motor and reducer are in good condition, and strictly check whether the size of each part of the motor connected to the reducer is match. Here is the size and fit tolerance of the motor's locating lug, input shaft and reducer groove.

減速機(jī)作為機(jī)械傳動的組成部分，其重要意義不言而喻。以便根據(jù)使用者的不同要求（使用場所，是否無人操作，是否在城區(qū)內(nèi)，地上、地下建筑物有無特定要求，是否有噪聲防護(hù)，或無其他特定要求）去滿足。減速機(jī)行業(yè)屬于國民經(jīng)濟(jì)發(fā)展的基礎(chǔ)行業(yè)，從生活家電到汽車飛機(jī)、從生產(chǎn)工具到建筑機(jī)械，幾乎所有的機(jī)械傳動系統(tǒng)中都需要使用到減速機(jī)。隨著市場需求的不斷深化，讓減速機(jī)市場得到快速發(fā)展，當(dāng)然減速機(jī)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(jī)的作用

1)降速同時(shí)提高輸出扭矩，扭矩輸出比例按步進(jìn)電機(jī)輸出乘減速比，但要注意不能超出減速機(jī)額定扭矩。

2)速同時(shí)降低了負(fù)載的慣量，慣量的減少為減速比的平方。大家可以看一下一般電機(jī)都有一個(gè)慣量數(shù)值。

The function of the reducer

1) reduce the speed and increase the output torque at the same time. The ratio of the torque output to the multiplying and decelerating ratio of the stepper motor output, but we must be careful not to exceed the rated torque of the reducer.

2) speed reduces inertia of load at the same time, and inertia reduces to the square of deceleration ratio. As you can see, general motors have an inertia value.

減速機(jī)內(nèi)部齒輪精度等級 設(shè)計(jì)減速機(jī)時(shí)，設(shè)計(jì)者往往從經(jīng)濟(jì)因素考慮，盡可能比較經(jīng)濟(jì)的確定齒輪精度等級，忽略精度等級是齒輪產(chǎn)生噪聲與側(cè)隙的標(biāo)記。

When the reducer is designed in the gear precision grade of the reducer, the designers often cider the economic factors as much as  to determine the gear precision level as much , and ignore the precision grade as the mark of the gear noise and the backlash.
