Foreword

GB/T 17587 "ball screw" is divided into five sections. --- Part 1. Terminology and symbols; --- Part 2. Nominal diameters and nominal leads - Metric series; --- Part 3. Acceptance conditions and acceptance tests; --- Part 4. Static axial stiffness; --- Part 5. Axial rated static and dynamic loads and service life. This section GB/T Part of 517,587. Modify using ISO 3408-5.2006 "axis ball screw Section 5 Amount Set of static and dynamic loads and the life "(in English). This part of ISO 3408-5.2006 as compared to the main changes are as follows. --- Taking into account the GB/T 17587.3-1998 "Ball Screw Part 3. Acceptance conditions and acceptance tests" standard ball screws Bar pairs standard tolerance grades have Level 2, Level 4 No case of 0, the table in section 6.1.3 of this 1, the standard tolerance level 0,1,3 and 5 to 1-5. --- Modify the corresponding provision in the margin by a vertical bar logo. For ease of use, this section also made the following editorial changes. --- Remove the foreword to international standards; --- The ISO 3408-5.2006 standard, "this International Standard" be replaced by "this section"; --- Use the decimal symbol instead of as a decimal comma ",". ","; --- "Using mathematical formula" × "instead of numbers and multiply the number of".. " This part is proposed by China Machinery Industry Federation.
