新聞資訊 >> 摩擦也能造成蝸輪減速機(jī)漏油-

蝸輪減速機(jī)在設(shè)計(jì)時(shí)出于提高運(yùn)行效率的目的，所采用的蝸輪都以有色金屬作為主要材料，蝸桿多使用硬質(zhì)鋼材，因此在滑動(dòng)摩擦傳動(dòng)的運(yùn)行過(guò)程中，蝸輪蝸桿減速機(jī)就會(huì)產(chǎn)生較大的熱量，提高減速機(jī)的溫度。蝸輪減速機(jī)的溫度升高，會(huì)導(dǎo)致減速機(jī)內(nèi)的各個(gè)零配件因熱脹系數(shù)不同而產(chǎn)生配合上的差異，形成配合面間隙。減速機(jī)所使用的潤(rùn)滑油等油液，也會(huì)在高溫的作用下變稀或變質(zhì)，形成泄漏或潤(rùn)滑失效。蝸輪減速機(jī)防止溫度升高的辦法是合理搭配蝸輪蝸桿的材質(zhì)，避免過(guò)度摩擦的出現(xiàn)，同時(shí)注意嚙合磨擦面的表面質(zhì)量，并選擇適合的潤(rùn)滑油。減速機(jī)降溫的另外一個(gè)直接辦法是加裝降溫裝置或降低使用環(huán)境的溫度。

上海諾廣機(jī)械有限公司提供蝸輪減速機(jī)、RV系列鋁殼蝸輪箱等內(nèi)容。廠家提供產(chǎn)品參數(shù)，外形尺寸及安裝尺寸等。來(lái)電：021-63731858，網(wǎng)站查詢：http://globalssoftware.com/html/product/27.html
