                                                    安陽機床主軸的技術要求
                                                    作者:    發布于:2013-10-31 11:42:26    文字:【】【】【
                                                        安陽機床軸承的使用中,SKF軸承占有非常大的比重。但是在對SKF軸承的使用過程中有一定的技術要求。下面就來看看對它有哪些要求。
                                                    安陽機床所用的主軸軸承

                                                        1、轉速與溫升:
                                                        科技的發展帶動了,機床主軸轉速提高,變速范圍擴大,所以對軸承運轉中穩定性的要求也有著高標準。機床主軸軸承溫升是限制軸承轉速的重要因素。通常情況下,正確選擇軸承類型、公差等級、配置方式、游隙(預載荷)大小、潤滑劑及潤滑方式等,能在一定程度上提高滾動軸承的高速性能。

                                                        2、壽命及承載能力:
                                                        普通機床,主軸組件的精度能夠保持的時間長短代表著它的壽命,所以對其精度需要有著長期的保持以達到我們的運轉要求。對于重型機床或強力切削機床,應首先考慮軸承的承載能力。

                                                        3、剛度和抗振性:
                                                        為保證機床的加工質量,必須使主軸系統有足夠的剛性,否則會產生較大的復映誤差甚至顫振。抗振性是指抵抗受迫振動和自激震動的能力。主軸組件的抗振性取決于主軸和軸承的剛度和阻尼。采用預緊滾動軸承可有效地提高主軸系統的剛度。

                                                        4、噪聲:
                                                        在高速磨床中,磨頭軸承的噪聲是整機噪聲中的主要成分,應選用低噪聲滾動軸承。
