機(jī)械制動(dòng)減速的怎樣操作？
答：（1）在減速階段開(kāi)始時(shí)，先將電動(dòng)機(jī)操作手柄由極端位置迅速地拉（或推）回到中間位置，然后操作制動(dòng)器手柄進(jìn)行機(jī)械制動(dòng)，使提升速度降低至爬行速度。
（2）施閘時(shí)切忌過(guò)快、過(guò)猛及制動(dòng)力過(guò)大，否則提升速度將急劇下降，不僅要二次給電，或加長(zhǎng)爬行階段時(shí)間，還由于減速度過(guò)大而使提升機(jī)的零部件和提升鋼絲繩受到較大的動(dòng)載荷。
?。?）施閘也不能過(guò)慢及制動(dòng)力過(guò)小，否則雖不會(huì)使提升機(jī)的零部件及提升鋼絲繩受到較大動(dòng)載荷，但有可能造成過(guò)卷事故。
?。?）為了實(shí)現(xiàn)減速階段速度圖，施加的制動(dòng)力應(yīng)盡可能符合設(shè)計(jì)值。這要根據(jù)設(shè)計(jì)減速時(shí)間、減速運(yùn)行距離的要求，經(jīng)過(guò)實(shí)踐來(lái)確定。
?。?）在制動(dòng)減速過(guò)程中，要特別注意提升速度的變化及深度指示器指示提升容器的位置，根據(jù)具體情況隨時(shí)調(diào)節(jié)制動(dòng)力的大小。
?。?）機(jī)械制動(dòng)減速操作的靈活性和準(zhǔn)確性，同所使用的提升機(jī)的制動(dòng)裝置的制動(dòng)力調(diào)節(jié)性能有關(guān)，操作工必須對(duì)所使用的制動(dòng)裝置的結(jié)構(gòu)、原理及制動(dòng)力的調(diào)節(jié)了解得非常透徹才行。

雙級(jí)減速機(jī)維護(hù)保養(yǎng)
雙級(jí)減速機(jī)在正常使用過(guò)程中，原有精度將會(huì)隨著工作的時(shí)間而變化。為了保持減速機(jī)的穩(wěn)定的工作性能，就必須得做好日常維護(hù)保養(yǎng)工作。蝸輪減速機(jī)潤(rùn)滑性能要保持良好，這是一項(xiàng)在保養(yǎng)減速機(jī)中極其重要的工作，因?yàn)樵谖佪單仐U工作時(shí)，蝸輪與蝸桿在嚙合處存在著較大的相對(duì)滑動(dòng)速度，引起很大的摩擦和發(fā)熱，使輪齒之間生磨損和膠合現(xiàn)象。
由于蝸輪輪齒輪的材料比蝸桿材料要軟得多，所以發(fā)生膠合時(shí)，蝸輪表面的金屬會(huì)粘到蝸桿的螺旋面上，使用蝸輪的工作齒面形成溝痕。當(dāng)潤(rùn)滑油不清潔或者潤(rùn)滑油油量不足、而未及時(shí)更換或補(bǔ)充時(shí)，就會(huì)影響金屬之間油膜的形成。在這種潤(rùn)滑不良的情況下若仍強(qiáng)迫減速機(jī)運(yùn)行，不僅會(huì)增加摩擦熱量，影響蝸桿的傳遞效率，而且蝸輪輪齒的磨損也會(huì)隨著增加。
由此可見(jiàn)。潤(rùn)滑是保證蝸輪蝸桿減速機(jī)正常工作的基本條件，因?yàn)闈?rùn)滑油能在蝸輪蝸桿的接觸面上形成油膜，從而避免金屬間的直接接觸，能有效地降低磨損。這對(duì)于降低磨損，提高傳動(dòng)效率，延長(zhǎng)蝸輪蝸桿減速機(jī)的使用壽命，保證減速機(jī)平穩(wěn)的工作。
