JB/T8854.1—2001
This standard is a revision of JB54,1—CL type station gear coupling. The main differences between this standard and JBT8854.1-1999 in terms of technical requirements are: the C, A, and self values ​​of GCLD drum gear couplings have been adjusted; the technical requirements, test methods, inspection rules, specifications, packaging and storage of GCLD drum gear couplings have been added: the specific gravity has been increased by 15%~20% compared with the original standard. This standard replaces JB/T8854.1-1999 from the date of implementation. This standard was proposed and approved by the Technical Committee for Standardization of Metallurgical Equipment of the Machinery Industry. The drafting unit of this standard: China Third Heavy Aircraft Corporation. The additional drafting units of this standard: Erzhiji Ship Parts Factory, Xi'an Machinery Research Institute, Gongzhou Coupling Factory. The main contributors of this standard: Yue Guangfa, Zhao Baozi. The previous versions of the standards replaced by this standard are: 2B9012-1989, 3B8854.1-1999. 1 Scope

Replacement JB/T R854.1=1994
This standard defines the type, basic data, main dimensions, technical requirements, test methods, inspection specifications, marking, packaging and maintenance of CLD type gear couplings. This standard is applicable to CLD type gear couplings that connect motors and mechanical axis transmission systems and have the function of angular compensation for relative displacement of the two axes. The working environment condensation is -20~+50%, and the transmission torque is 1.12~50kN·m2. Reference standards
The following standards contain provisions that constitute standard provisions by reference in this standard. When this standard is published, the versions shown are not valid and all other standards will be revised. Parties using this standard should explore the possibility of using the latest version of the following standards.
