大接觸角度的圓錐滾子軸承往往經(jīng)常用在減速機(jī)中,這是根據(jù)減速機(jī)的使用特點(diǎn)設(shè)計(jì)的,在旋轉(zhuǎn)過(guò)程中,減速機(jī)軸承因采用渦輪蝸齒旋轉(zhuǎn),會(huì)產(chǎn)生向一個(gè)方向的旋轉(zhuǎn)力,這對(duì)受力方向產(chǎn)生很大的軸向載荷,普通的圓錐滾子軸承接觸角度小,使用時(shí)會(huì)因?yàn)榫薮蟮妮d荷使?jié)L子在滾道上產(chǎn)生應(yīng)力挫傷,在快速旋轉(zhuǎn)時(shí)會(huì)產(chǎn)生較大噪音,長(zhǎng)時(shí)間使用后會(huì)造成滾子跳動(dòng),而采用大角度圓錐滾子軸承,增加的接觸面積和大的承受角度會(huì)分散應(yīng)力,以減少軸向載荷對(duì)滾子軸承的傷害。北京亞康進(jìn)口軸承公司專(zhuān)業(yè)銷(xiāo)售各種減速機(jī)軸承,在對(duì)各種減速機(jī)軸承的安裝和損壞都可進(jìn)行技術(shù)指導(dǎo),歡迎咨詢。
