引言

張緊輪是發(fā)動(dòng)機(jī)附件帶傳動(dòng)系統(tǒng)應(yīng)用的關(guān)鍵部件，其主要起到傳動(dòng)系統(tǒng)張緊力調(diào)節(jié)作用，使傳動(dòng)系

統(tǒng)張緊力保持穩(wěn)定狀態(tài)，既能實(shí)現(xiàn)降噪減振，又能提高帶傳動(dòng)系統(tǒng)使用壽命和傳動(dòng)精度。張緊輪發(fā)展至

今幾經(jīng)技術(shù)變化，目前均具備自動(dòng)張緊功能，其能夠根據(jù)附件帶的長(zhǎng)度變化自動(dòng)調(diào)節(jié)系統(tǒng)張緊力，一般

可分為機(jī)械式自動(dòng)張緊輪和液壓式自動(dòng)張緊輪，由于機(jī)械式自動(dòng)張緊輪應(yīng)用較為普遍，本文件給出了機(jī)

械式自動(dòng)張緊輪的試驗(yàn)方法。

1范圍

本文件描述了發(fā)動(dòng)機(jī)附件帶傳動(dòng)系統(tǒng)機(jī)械式自動(dòng)張緊輪（以下簡(jiǎn)稱(chēng)“張緊輪”）的試驗(yàn)說(shuō)明、試驗(yàn)

方法及試驗(yàn)報(bào)告。試驗(yàn)方法主要包括高溫耐久性試驗(yàn)、冷熱沖擊耐久性試驗(yàn)、腐蝕試驗(yàn)、污染試驗(yàn)、提

起試驗(yàn)、耐臭氧試驗(yàn)、跌落試驗(yàn)及急扭試驗(yàn)。

本文件適用于發(fā)動(dòng)機(jī)應(yīng)用的機(jī)械式自動(dòng)張緊輪，不適用于張緊輪中帶輪或軸承、直線式張緊輪和雙

向張緊輪。
