1、以負(fù)載確定直徑電機(jī)性能參數(shù)中有輸出扭矩，如果還帶減速器也要算進(jìn)去（考慮效率），計(jì)算一下實(shí)際工況中需要多大推力，滾珠絲杠軸承樣本（跟廠家要）有負(fù)載參數(shù)（即推力參數(shù)，一般標(biāo)示為動負(fù)荷和靜負(fù)荷，看前者即可），選擇滾珠絲杠軸承的公稱直徑。 2、以直線速度和旋轉(zhuǎn)速度確定滾珠絲杠軸承導(dǎo)程電機(jī)確定了就知道輸出轉(zhuǎn)速，考慮一下你需要的至大直線速度，把電機(jī)轉(zhuǎn)速（如果帶減速器再除以減速比）乘以絲杠軸承導(dǎo)程的值就是直線速度，該值大于需要值即可。鎮(zhèn)江7602070TN-2RZ絲杠軸承經(jīng)銷商</p><p
