Lundberg and A. Palmgren Acta Politechnica, mech. Eng. series Vol. I, No. 3, Stockholm, Sweden. Part 7, 1947.This part of ISO 3408 is applicable under the following preconditions:— elastic deformation of ball and balltrack;— hardness of balltrack basically exceeds a minimum of HRC 58;— conformity/rs andfm> 0,5;— the quality of steel of which the ball screw is made is equivalent to that of ball bearing steel or similar steel alloys;— optimum lubrification is always provided.【中国标准分类号】: J51【国际标准分类号】: 25_060_99【页数】: 14P;A4【正文语种】: 英语
