ICS 21.120.20 Machinery Industry Standard of the People's Republic of China JB/T8869-2000 Snake Spring Coupling Steelfler couplings Published on April 24, 2000 Implementation on October 1, 2000 by the State Machinery Industry Bureau of the People's Republic of China JET 8869-2000 Cited standards Structural type, basic parameters and main dimensions4 5Technical requirements 6Test methods· Inspection and measurement Marking, installation, etc. Appendix A (Appendix to the standard)JSJ Plastic intermediate shaftNumber of spring-lock couplingsIntermediate shaft length verification35 JE/T8869-2000 This The standard is a general reference to JB/T8869-1999 (7B/TJ19023-90) "Static setting of serpentine spring couplings". The main differences between this standard and the previous standard are: including JS, JSB, JSS, JSD, JSJ, JS, JSZ, JSP, JSA9 types; JS type 25 specifications; each specification stipulates a shaft hole length; Appendix A JSI type intermediate shaft type serpentine spring coupling intermediate shaft length verification is added. This standard replaces 8869-1999 from the date of implementation. Appendix A of this standard is the appendix of the standard. This standard was proposed and coordinated by the National Technical Committee for Standardization of Machine Group Shafts and Accessories. The units that initiated this standard are: Machinery and Sugar Science Research Institute, American Fokker Company. This standard mainly refers to: Shang Mingheng, Xing Shoujing, Ming Cui Xin Zheng Yi 1 Scope Machinery Industry Standard of the People's Republic of China Steelflex conplings JE/T B869—2000 JBB69—1990 This standard specifies the classification, type and parameters, technical requirements, test methods, inspection rules, marking, packaging and storage of JS, JSB, JS, JSD, JSJ, JSO, JSZ, JSP and JSA serpentine spring couplings (hereinafter referred to as couplings). This standard is applicable to medium and large power transmission shafts that connect two coaxial lines, and have certain compensation for the relative displacement of the two shafts and vibration reduction and impact performance, with a working degree of -30T~+150%, and a transmission nominal torque of 45-800000N·m. 2 Referenced standards The following standards contain service documents, which are cited in this standard and constitute the documents recommended by this standard. When this standard is published, the short versions shown are valid, and all standards will be revised.
