新聞資訊 >> 摩擦也能造成蝸輪減速機漏油-

蝸輪減速機在設計時出于提高運行效率的目的，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，因此在滑動摩擦傳動的運行過程中，蝸輪蝸桿減速機就會產(chǎn)生較大的熱量，提高減速機的溫度。蝸輪減速機的溫度升高，會導致減速機內(nèi)的各個零配件因熱脹系數(shù)不同而產(chǎn)生配合上的差異，形成配合面間隙。減速機所使用的潤滑油等油液，也會在高溫的作用下變稀或變質(zhì)，形成泄漏或潤滑失效。蝸輪減速機防止溫度升高的辦法是合理搭配蝸輪蝸桿的材質(zhì)，避免過度摩擦的出現(xiàn)，同時注意嚙合磨擦面的表面質(zhì)量，并選擇適合的潤滑油。減速機降溫的另外一個直接辦法是加裝降溫裝置或降低使用環(huán)境的溫度。
