This standard is a revision of JB/T 7934-95 "Types and basic parameters of expansion sleeves". During the revision, the types were added, and some calculation formulas and technical contents were adjusted. This standard specifies the types and basic types of Z1~Z20 expansion sleeves. This standard is applicable to expansion sleeves that connect shafts and shafts as parts. This standard was first issued on February 21, 1986 as GB 5867-86 and was adjusted to JB/T 7934-95 in April 1996.

Some standard content:
JB/T 7934 1999 This standard is a revision of J13/T7934 Types and basic dimensions. 95 "Expansion coupling sets" Compared with J13/T793495, the main technical content changes are as follows: ~5 types are added; Table A5~Table A9 in Appendix A are cancelled: The formula for calculating the hub outer diameter according to the service limit of the hub material is adopted: Appendix B is changed to Appendix C. Attached requirements (for Z, the connection design points of the expansion coupling sets) This standard replaces J13/T7934:95 from the date of implementation. Appendix A, Appendix B and Appendix C are both informative appendices. This standard was proposed and managed by the Metallurgical Equipment Standardization Technical Committee. The drafting units of this standard are: China Second Heavy Machinery Group Corporation, Deyin Erzhong Basic Parts Factory. The main drafters of this standard are: Zhao Binghou, Zhao Baoyu, Zhao Guangfa. This standard was first issued in February 1986. 1 Scope Machinery Industry Standards of the People's Republic of China Expansion Coupling Sleeves Types and Basic Dimensions Types This standard specifies the types and basic dimensions of locking assemhlies of Type Z to Type B. This standard applies to locking assemhlies for connecting shafts and parts on shafts. 2 Reference standards JB/T7934 Replaces JB/T793493 The following standards contain provisions that constitute the provisions of this standard by citing them in this standard.
