輕型系列回轉(zhuǎn)支承
2017年2月10日三排滾柱式回轉(zhuǎn)支承(13系列)
2017年2月11日雙列球式回轉(zhuǎn)支承
雙列球式回轉(zhuǎn)支承由兩排球式滾動(dòng)體組成,能同時(shí)承受較大的軸向載荷、徑向載荷和傾覆力矩,安全系數(shù)更高。被廣泛應(yīng)用于中大型起重機(jī)、礦山設(shè)備、挖掘機(jī)等機(jī)械設(shè)備。
雙列球式回轉(zhuǎn)支承主要由內(nèi)圈、外圈、兩排滾動(dòng)體(鋼球)、保持架和密封裝置組成。其內(nèi)圈和外圈通常有多個(gè)安裝孔,用于固定在設(shè)備上。滾動(dòng)體在保持架或者隔離塊的引導(dǎo)下,在內(nèi)外圈之間滾動(dòng),確保平穩(wěn)的旋轉(zhuǎn)運(yùn)動(dòng)。
注:1、n1為潤(rùn)滑油孔數(shù)。油杯M10×1JB/T7940.1~JB/T7940.2。根據(jù)實(shí)際應(yīng)用情況用戶可指定油孔位置。
2、n-?可改為螺紋孔,螺紋孔直徑M,螺紋深度2M。
3、本樣本中的規(guī)格為標(biāo)準(zhǔn)產(chǎn)品,內(nèi)外徑均為自由公差。若主機(jī)與回轉(zhuǎn)支承有配合要求,請(qǐng)?jiān)诤贤蚝贤郊ㄈ缂夹g(shù)協(xié)議)中注明配合尺寸和精度。
4、表中所列為我公司常規(guī)產(chǎn)品,若有其他特殊要求,請(qǐng)與我公司聯(lián)系。
