天輪襯墊出現磨損的原因

天輪襯墊出現磨損的原因

天輪襯墊是提升機關(guān)鍵部位之一，提升機選用的襯墊材料多為聚錄乙烯，聚氨脂類(lèi)，這類(lèi)材料與鋼絲繩對偶摩擦系數高，具有較高的耐壓性，耐磨性，摩擦系數一般為0.2.多數在使用過(guò)程中不注意會(huì )磨損，那出現磨損的原因是什么?

天輪襯墊的摩擦系數介紹

天輪襯墊的摩擦系數介紹

摩擦系數是評價(jià)任何一種摩擦材料的一個(gè)重要的性能指標，關(guān)系著(zhù)天輪襯墊執行傳動(dòng)和制動(dòng)功能的好壞。它不是一個(gè)常數，而是受溫度、壓力、摩擦速度或表面狀態(tài)及周?chē)橘|(zhì)因素等影響而發(fā)生變化的一個(gè)數。理想的摩擦系數應具有理想的冷摩擦系數和可以控制的溫度衰退。由于摩擦產(chǎn)生熱量，增高了工作溫度，導致了摩擦材料的摩擦系數發(fā)生變化。

摩擦襯墊性能有哪些呢

摩擦襯墊性能有哪些呢

襯墊在上述性能中主要的是摩擦系數,提升摩擦系數,將會(huì )提升設備的經(jīng)濟性和安全性,目前國內主要采用聚氨酯襯墊和高性能摩擦襯墊,磨擦系數分別為0.2、0.23和0.25.特別是高性能摩擦襯墊,它能確保設計使用磨擦系數達到0.25.GDM-326摩擦襯墊的摩擦系數達到0.28.同時(shí)具有較高的熱穩定性和耐摩性,越來(lái)越受到用戶(hù)的青睞。

中實(shí)重機生產(chǎn)大齒圈磨機傳動(dòng)裝置

中實(shí)重機生產(chǎn)大齒圈磨機傳動(dòng)裝置

大齒圈作為回轉窯、球磨機、烘干機等機械的重要部件之一，，所以齒圈的好壞關(guān)系到球磨機、回轉窯的穩定性和使用壽命。大齒圈是球磨機、回轉窯傳動(dòng)裝置中很關(guān)鍵的一個(gè)部件，它帶動(dòng)整個(gè)筒體長(cháng)時(shí)間低速旋轉，其質(zhì)量直接影響著(zhù)球磨機、回轉窯傳動(dòng)系統的平穩性、運行的穩定性、內襯的使用壽命及窯、磨的運轉率，因此大齒圈在實(shí)際生產(chǎn)中質(zhì)量要求很高。

提升機摩擦襯墊的發(fā)展及特點(diǎn)

提升機摩擦襯墊的發(fā)展及特點(diǎn)

摩擦襯墊是提升機上的一個(gè)關(guān)鍵部件，它直接決定了提升機的提升能力。按照襯墊摩擦系數的高低，襯墊分為普通襯墊和高性能襯墊。高性能襯墊是指在有油脂情況下摩擦系數>0.25的襯墊。

淺析大型磨機襯板使用壽命的影響因素

淺析大型磨機襯板使用壽命的影響因素

我國鑄造耐磨材料經(jīng)過(guò)數十年的快速發(fā)展，現已較廣的應用于礦山、冶金、建材、電力及化工等行業(yè)。據統計，國內鋼鐵耐磨鑄件年消耗 350萬(wàn) t以上，預計總需求量年增長(cháng) 5%～ 10%。由此可以看出，耐磨材料產(chǎn)業(yè)具有廣闊的發(fā)展前景。
