YRT轉(zhuǎn)臺(tái)軸承

YRT標(biāo)準(zhǔn)系列

推力-向心組合結(jié)構(gòu),可同時(shí)承受雙向軸向載荷、徑向載荷和傾覆力矩。軸承上均布有安裝孔,可使用螺栓直接對(duì)軸承固定;出廠時(shí)軸承已加有預(yù)載荷,安裝無(wú)需調(diào)整游隙;YRT轉(zhuǎn)臺(tái)軸承系列適用于轉(zhuǎn)速較低、運(yùn)轉(zhuǎn)周期較短、對(duì)剛性和精度要求高的場(chǎng)合,如回轉(zhuǎn)工作臺(tái)、分度頭。


YRT轉(zhuǎn)臺(tái)軸承由一個(gè)推力/向心軸圈,一個(gè)推力墊圈,兩個(gè)滾針保持架組件和一組向心圓柱滾子組成。 座圈和軸圈有均布的安裝用螺釘孔。該型軸承具有高軸向和徑向承載能力。高傾斜剛度和極高的精度。適用于回轉(zhuǎn)工作臺(tái),卡盤和銑刀頭以及測(cè)量和實(shí)驗(yàn)中的軸承配置。該型軸承對(duì)與之相配的設(shè)備零件的要求也較高。安裝時(shí)需控制安裝螺釘?shù)呐ぞo力矩。

適用范圍:被廣泛應(yīng)用于精密回轉(zhuǎn)臺(tái)立式磨床、分度頭、滾齒機(jī)、銑齒機(jī)工件軸等精密裝置。
