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果，大小齒輪的齒數(shù)之比，就是傳動比。（就是“降低轉(zhuǎn)速，增大扭矩，減小慣量”）
減速機是一種動力傳達機構(gòu)，利用齒輪的速度轉(zhuǎn)換器，將電機（馬達）的回轉(zhuǎn)數(shù)減速到所要的回轉(zhuǎn)數(shù)，并得到較大轉(zhuǎn)矩的機構(gòu)。在目前用于傳遞動力與運動的機構(gòu)中，減速機的應用范圍相當廣泛。
減速機作用
1、降速同時提高輸出扭矩，扭矩輸出比例按電機輸出乘減速比，但要注意不能超出減速機額定扭矩。
2、減速同時降低了負載的慣量，慣量的減少為減速比的平方。大家可以看一下一般電機都有一個慣量數(shù)值。
減速機速比
速比=電機輸出轉(zhuǎn)數(shù)÷減速機輸出轉(zhuǎn)數(shù)("速比"也稱"傳動比")
減速機扭矩計算公式
減速機扭矩=9550×電機功率÷電機功率輸入轉(zhuǎn)數(shù)×速比×使用效率(60%-96%)

減速機的電動機：
（1）電動機的日常維護
日常維護對減少和避免減速機的電動機在運行中發(fā)生故障是相當重要的,其中重要的環(huán)節(jié)是巡回檢查和及時排除任何不正?，F(xiàn)象的引發(fā)根源.出現(xiàn)事故后認真進行事故分析,采取對策,則是減少事故次數(shù)和修理停歇臺時提高電機運行效率必不可少的技術(shù)工作.電機的日常維護對其正常運行固然非常重要,但運行中的電機往往會遇到許多突發(fā)情況,如短路,過載,斷相等.為了使電機在出現(xiàn)這些情況的條件下不至于被損壞,必須采取一些運行保護措施保持電機清潔.電機內(nèi)部不允許進入水珠,油污,灰塵等,并定期清除電機內(nèi)外的灰塵.
注意負載電流不要超過額定值.
注意檢查軸承發(fā)熱,漏油等情況,尤其要按規(guī)定加油.
電機的溫升不能超過額定值.

鋁門窗在現(xiàn)場安裝時，裝配尺寸控制不好，致使相互有搭接密封的位置相互錯位或搭接尺寸不足，或因壓力足而有間隙，用于固定門窗框的緊固螺絲沒有閉膠封堵，用密封膠密封時未清潔密封部位的表面等。鋁門窗使用的密封材料太差，如膠條過硬，抗老化時間短，密封膠過時使用或是冒牌假膠，抗變位能力差、易拉裂等。鋁門窗加工制作精度達不到質(zhì)量要求，配合間隙過大，需粘接后組裝的部位沒有涂密封材料而直接組裝，造成雨水輕易通過各種裝配間隙滲透門窗及主體結(jié)構(gòu)之內(nèi)。

蒸汽管道的補償器的作用:主要為保障管道安全運行，具有以下作用：1.補償吸收管道軸向、橫向、角向熱變形。吸收設(shè)備振動，減少設(shè)備振動對管道的影響。吸收地震、地陷對管道的變形量。補償器在冷時伸長還是熱時伸長？當管道介質(zhì)低于2度時，管道受溫度影響收縮，這時補償器伸長。介質(zhì)在2度以上時，管道膨脹伸長，補償器壓縮。介質(zhì)保持2度不變時，補償器保持原位不變。蒸汽管道在受熱后會膨脹伸長，如果不將這部分伸長量有效吸收，將造成管道支架受推力影響而損壞，嚴重的將造成管道脫落。
