安裝前確認電機和減速機是否完好無損，并且嚴格檢查電機與減速機相連接的各部位尺寸是否匹配，這里是電機的定位凸臺、輸入軸與減速機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.

減速器是一種由封閉在剛性殼體內的齒輪傳動、蝸桿傳動、齒輪-蝸桿傳動所組成的獨立部件，常用作原動件與工作機之間的減速傳動裝置 。在原動機和工作機或執(zhí)行機構之間起匹配轉速和傳遞轉矩的作用，在現(xiàn)代機械中應用極為廣泛。

The reducer is an independent component  of gear transmission, worm drive and gear worm drive enclosed in a rigid shell. It is often used as a deceleration between the original and the working machines. The matching speed and transfer torque between prime movers and working machines or actuators are widely applied in modern machines.

減速機作為機械傳動的組成部分，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，地上、地下建筑物有無特定要求，是否有噪聲防護，或無其他特定要求）去滿足。減速機行業(yè)屬于國民經(jīng)濟發(fā)展的基礎行業(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。

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.

減速機內部齒輪寬度 在減速機傳動空間允許時，增加齒輪寬度，可以減少恒定扭矩下的單位負荷。降低輪齒撓曲，減少噪聲激勵，從而降低傳動噪聲。

The width of the internal gear of the reducer can be increased when the transmission space of the reducer is allowed, so that the unit load under ctant torque can be reduced. Reduce gear deflection, reduce noise excitation, thereby reducing transmission noise.
