如果傳動皮帶的伸長量沒有超過，那么如果你的車配備了主動張緊器，你應(yīng)該集中精力。啟動發(fā)射器，試著加載輔助傳動機(jī)構(gòu)（如燈、空調(diào)、車輪轉(zhuǎn)動等），然后觀察皮帶張緊臂；發(fā)動機(jī)工作時，皮帶張緊器的懸掛管應(yīng)有小位移。如果帶預(yù)緊器不可移動，則起動機(jī)關(guān)閉，工人在皮帶預(yù)緊器的懸掛管的工作行程內(nèi)移動起動機(jī)，該行程約為1/4英寸的位移。如果皮帶預(yù)緊器無法移動，則說明皮帶預(yù)緊器出現(xiàn)故障，應(yīng)及時更換。如果皮帶張緊器懸臂的位移超過1/4英寸，則彈簧負(fù)載明顯過小，這將導(dǎo)致皮帶打滑。如果再次拆下普通皮帶，如果與平時一樣，只需更換皮帶張緊器。
If the drive belt does not extend more than that, then if your car is equipped with active tensioners, you should concentrate. First start the transmitter, try to load the auxiliary transmission mechanism (such as lamp, air conditioner, wheel rotation, etc.), and then observe the belt tension arm; when the engine is working, the suspension pipe of the belt tensioner should have small displacement. If the seat belt pretensioner is not removable, the starter is turned off and the worker moves the starter within the working stroke of the suspension tube of the belt pretensioner, which is approximately 1 / 4 inch displacement. If the belt pretensioner cannot be moved, it indicates that the belt pretensioner is faulty and should be replaced in time. If the displacement of the belt tensioner cantilever exceeds 1 / 4 inch, the spring load is significantly too small, which will cause the belt to slip. If the ordinary belt is removed again, if it is the same as usual, just replace the belt tensioner.
如果皮帶沒有過度拉伸且主動張緊裝置工作狀態(tài)良好，請查看皮帶的工作面是否可以像鏡子一樣磨光。這是皮帶過度磨損導(dǎo)致皮帶打滑的典型例子?；啽砻娴挠推峋褪腔瑒拥淖C據(jù)。
If the belt is not over stretched and the active tensioning device is in good working condition, check whether the working surface of the belt can be polished like a mirror. This is a typical example of belt slippage caused by excessive belt wear. The paint on the surface of the pulley is evidence of sliding.
如果皮帶只在潮濕的天氣下吱吱作響，皮帶和皮帶輪表面也將得到潤滑。讓我們做同樣的實(shí)驗：讓輔助傳動系統(tǒng)帶負(fù)荷工作，用灑水器在軟管上灑水。如果有噪音，請更換皮帶。
If the belt squeaks only in wet weather, the belt and pulley surfaces will also be lubricated. Let's do the same experiment: let the auxiliary drive system work with load and spray water on the hose with a sprinkler. If there is noise, replace the belt.
長時間尖叫或反耳噪音
Long time squeal or anti ear noise
雖然皮帶輪表面由于沙子或舊皮帶等污垢而向后安裝，但皮帶可能會因長尖叫聲或反耳噪音而縮回，但這通常是由于輔助機(jī)構(gòu)的不正確拆卸造成的。
Although the surface of the pulley is installed backward due to dirt such as sand or old belts, the belt may retract due to long squeaks or anti ear noises, which are usually caused by incorrect removal of auxiliary mechanisms.
如果噪音是在一輛新車即將啟動時發(fā)出的，可能是由于原制造廠的質(zhì)量差。檢查您認(rèn)為可能導(dǎo)致問題的相關(guān)部分。如果以上噪音發(fā)生在一輛舊車上，那么您應(yīng)該考慮是否可以完全更換一些輔助執(zhí)行器的相關(guān)附件。仔細(xì)查看已更換的零件（如開關(guān)發(fā)電機(jī)、動力轉(zhuǎn)向泵等），看其安裝支架是否牢固牢固。另外，在安裝過程中保持墊圈或襯套在適當(dāng)?shù)奈恢?，它們也可以拆下皮帶輪?/div>
If the noise is emitted when a new car is about to start, it may be due to the poor quality of the original manufacturer. Check the relevant parts that you think may cause the problem. If the above noise occurs in an old car, you should consider whether it is possible to completely replace some accessories related to auxiliary actuators. Carefully check the replaced parts (such as switch generator, power steering pump, etc.) to see whether the mounting bracket is firm and firm. In addition, they can also be removed by keeping the washer or bushing in place during installation.
拆下正時齒輪皮帶并在安裝后立即調(diào)整。這就是指示正時皮帶旋轉(zhuǎn)方向的原因。如果由于其他維護(hù)工作而在拆下正時齒輪后拆下時尚齒輪，則可以在皮帶移動時聽到尖銳的后耳吱吱聲。你試著倒轉(zhuǎn)皮帶的安裝方向，看看問題是否能。
Remove timing gear belt and adjust immediately after installation. This is the reason for indicating the direction of rotation of the timing belt. If the fashion gear is removed after the timing gear is removed due to other maintenance work, a sharp rear ear squeak can be heard as the belt moves. You try to reverse the direction of the belt installation to see if the problem can be eliminated.
間歇嗡嗡聲或嗡嗡聲隨啟動器速度增加而增大，這意味著輔助驅(qū)動機(jī)構(gòu)的軸承缺油。借助聽診器，你可以進(jìn)一步檢查噪音。然后拆下傳動帶，用手轉(zhuǎn)動可疑的有缺陷的零件。如果轉(zhuǎn)動困難或聲音粗糙且耳朵縮回，不要更換軸承或相應(yīng)的零件。但是，需要注意的是，每次更換輔助傳動部件時，不要忘記更換皮帶張緊裝置和主動張緊裝置。
Intermittent hum or buzz increases with the speed of the starter, which means that the bearings of the auxiliary drive mechanism are short of oil. With the help of stethoscope, you can further check the noise. Then remove the drive belt and turn the suspected defective part by hand. If it is difficult to turn or the sound is rough and the ears are retracted, do not replace the bearing or corresponding parts. However, it should be noted that the belt tensioning device and the active tensioning device should not be forgotten to replace each auxiliary transmission component.
