減速機(jī)的噪音產(chǎn)生主要是源于傳動齒輪的摩擦、振動以及碰撞，如何有效降低噪聲，我們在使用過程中應(yīng)該注意哪些問題，下面為大家介紹減速機(jī)噪聲的使用維護(hù)內(nèi)容有哪些。
及時的潤滑和正確使用油品
不合理的潤滑和錯誤的使用潤滑油脂都將對減速機(jī)產(chǎn)生不可估量的損害。高轉(zhuǎn)速時，齒輪齒面摩擦?xí)a(chǎn)生大量的熱能，潤滑不當(dāng)，將會導(dǎo)致輪齒的損傷，影響精度，噪聲亦會增大。設(shè)計時要求齒輪副有適當(dāng)?shù)拈g隙(嚙合輪齒的非工作面間的間隙，以補(bǔ)償熱變形與貯存潤滑油脂)。潤滑油脂的正確使用和選擇，可保證系統(tǒng)安全有效運(yùn)行，延緩劣化趨勢，穩(wěn)定噪聲等級。

有數(shù)千家電線電纜生產(chǎn)企業(yè)，質(zhì)量參差不齊。對于廣大用戶而言，從眾多的電線電纜品牌中挑選出優(yōu)質(zhì)的產(chǎn)品就顯得非常復(fù)雜。電纜網(wǎng)小編從網(wǎng)絡(luò)收集到以下五種辨別電線電纜質(zhì)量優(yōu)劣的辦法，供廣大用戶參考：用眼看一看有無質(zhì)量體系認(rèn)證書；二看合格證是否規(guī)范；三看有無廠名、廠址、檢驗(yàn)章、生產(chǎn)日期；四看電線上是否印有商標(biāo)、規(guī)格、電壓等產(chǎn)品明細(xì)。用手試可取一根電線頭用手反復(fù)彎曲，凡是手感柔軟、抗疲勞強(qiáng)度好、塑料或橡膠手感彈性大且電線絕緣體上無裂痕的就是優(yōu)等品。

伺服的基本概念是準(zhǔn)確、、快速定位。變頻是伺服控制的一個必須的內(nèi)部環(huán)節(jié)，伺服驅(qū)動器中同樣存在變頻（要進(jìn)行無級調(diào)速）。但伺服將電流環(huán)速度環(huán)或者位置環(huán)都閉合進(jìn)行控制，這是很大的區(qū)別。除此外，伺服電機(jī)的構(gòu)造與普通電機(jī)是有區(qū)別的，要滿足快速響應(yīng)和準(zhǔn)確定位?，F(xiàn)在市面上流通的交流伺服電機(jī)多為永磁同步交流伺服，但這種電機(jī)受工藝限制，很難做到很大的功率，十幾KW以上的同步伺服價格及其昂貴，這樣在現(xiàn)場應(yīng)用允許的情況下多采用交流異步伺服，這時很多驅(qū)動器就是高端變頻器，帶編碼器反饋閉環(huán)控制。所謂伺服就是要滿足準(zhǔn)確、、快速定位，只要滿足就不存在伺服變頻之爭。

為避免鋁天花吊頂出現(xiàn)不平整現(xiàn)象，在裝飾施工過程中應(yīng)注意以下幾點(diǎn)：(l)購買的鋁天花和與之配套的龍骨、配件應(yīng)符合產(chǎn)品質(zhì)量要求，不得有彎曲變形。在運(yùn)輸和堆放過程中，鋁天花要擱置平整，不能受壓，并避免高溫和有害物質(zhì)的侵蝕。龍骨安裝平整，間距偏差應(yīng)控制在允許范圍1.5米之內(nèi)。安裝鋁天花時，如尺寸有偏差應(yīng)先予調(diào)整后按順序鑲插，不得硬插，以防變形。大型燈具、排氣扇等物應(yīng)單獨(dú)做龍骨固定，不應(yīng)直接擱置在鋁天花上。
