style="text-indent:25px">在實(shí)際應(yīng)用中，滾動(dòng)軸承的結(jié)構(gòu)形式有很多。作為標(biāo)準(zhǔn)的滾動(dòng)軸承，在國家標(biāo)準(zhǔn)中分為13類，接下來介紹其中幾種：1、深溝球軸承，深溝球軸承的類型代號(hào)為6，主要承受徑向載荷，也可同時(shí)承受小的軸向載荷。這種軸承大量生產(chǎn)，價(jià)格更低，使用更廣。2、圓柱滾子軸承，圓柱滾子軸承的類型代號(hào)為N。它的外圈和內(nèi)圈可以分離，無法承受軸向載荷，滾子由內(nèi)圈（或外圈）的擋邊進(jìn)行軸向定位。有較大的徑向承載能力。此類軸承可以不帶外圈或內(nèi)圈使用。3、圓錐滾子軸承，類型代號(hào)為3?？梢酝瑫r(shí)承受徑向載荷及軸向載荷，外圈可以分離。和角接觸球軸承一樣，圓錐滾子也一般成對(duì)使用。實(shí)踐證明：若將磨削速度由35m/s提高到50～60m/s時(shí)，一般生產(chǎn)效率可提高30%～60%。天津電機(jī)壓軸承</p><p style="text-indent:25px">磨削加工這個(gè)復(fù)雜性表現(xiàn)在：所要求的性能指標(biāo)更多、精度更高；加工參數(shù)在線檢測(cè)困難。天津電機(jī)壓軸承</p><p style="text-indent:25px">主軸錐孔相對(duì)于支承軸頸的位置精度是靠采用支承軸頸A、T作為定位基準(zhǔn)，而讓被加工主軸裝夾在磨床工作臺(tái)上加工來保證。以支承軸頸作為定位基準(zhǔn)加工內(nèi)錐面，符合基準(zhǔn)重合原則。在精磨前端錐孔之前，應(yīng)使作為定位基準(zhǔn)的支承軸頸A、T達(dá)到一定的精度。主軸錐孔的磨削一般采用**夾具，夾具由底座、支架、及浮動(dòng)夾頭三部分組成，兩個(gè)支架固定在底座上，作為工件定位基準(zhǔn)面的兩段軸頸放在支架的兩個(gè)V形塊上，V形塊鑲有硬質(zhì)合金，以提高耐磨性，并減少對(duì)工件軸頸的劃痕，工件的中心高應(yīng)正好等于磨頭砂輪軸的中心高，否則將會(huì)使錐孔母線呈雙曲線，影響內(nèi)錐孔的接觸精度。后端的浮動(dòng)卡頭用錐柄裝在磨床主軸的錐孔內(nèi)，工件尾端插于彈性套內(nèi)，用彈簧將浮動(dòng)卡頭外殼連同工件向左拉，通過鋼球壓向鑲有硬質(zhì)合金的錐柄端面，限制工件的軸向竄動(dòng)。采用這種聯(lián)接方式，可以保證工件支承軸頸的定位精度不受內(nèi)圓磨床主軸回轉(zhuǎn)誤差的影響，也可減少機(jī)床本身振動(dòng)對(duì)加工質(zhì)量的影響。天津電機(jī)壓軸承</p><p
