GB/T 9146-2003 Limit dimensions of common thread roughness and preferred series

This standard specifies the roughness, preferred series, and the limit sizes of the middle diameter and top diameter of coarse thread according to the basic deviations and tolerances of GB/T9144-2003 and GB/T197-2003. The basic tooth profile of ordinary thread complies with the provisions of GB/T192-2003 and is suitable for general-purpose mechanical fastening threaded connections. The thread itself does not have a sealing function.

This standard is different from B3, and the size specification has changed. The effective nominal diameter range in the standard text is 1mr-39mm, and the rated diameter range is 42m~m. The measured screw grade is A (reference part, while the effective nominal diameter in the standard text is mm61nmar. This standard is the limit size of the entire effective series standard. The standard package for the screw effective series is 20.

Order accuracy is excellent, the limit size is excellent, the relative accuracy is excellent This standard was proposed by the Standardization Technical Committee (SAI) under the supervision of the Ministry of Industry and Information Technology. The responsible drafting unit of this standard is the Institute of Mechanical Engineering. The main drafters of this standard are Li Xiaobin, Changle Standard 1988, General thread roughness accuracy, preferred series limit size TA/T9146-2003 This standard According to the G/T9:442005 system and GB19?203 basic assumptions and tolerances, the diameter and diameter of the thread of the corresponding ordinary thread (-thread thread) are determined. The effective cost technology conforms to the provisions of G/T192-20G. The machine used for general belt fastening is used for the joint compensation, and its ticket has no sealing function: 2 Normative references The following documents The clauses in this document become the clauses of this standard through reference. All the referenced documents in the specified period are subject to the revision of the standard (excluding the revision of the content or revision of the standard). However, the parties are encouraged to study whether the latest version of this document can be used: the latest version of this standard is the reference of the technical juice mountain period, and the latest version is applicable to this standard 193 general text base 43-199810ws
