This standard is proposed and managed by the National Technical Committee for Standardization of Machine Shafts and Accessories. The responsible drafting unit of this standard is China Second Heavy Machinery Group Co., Ltd. Xi'an Heavy Machinery Research Institute. The main drafters of this standard are Lv Wanluo, Yue Baozi, Yue Guangfa, Zhang Ziming, and Zhang Guangye. This standard is published for the first time: 1 Scope Machinery Industry Standard of the People's Republic of China WGJ Crowned teeth cnuplinga witliatarcamnctlnt shaft-Type,parameiere and dimensions wGJ Crowned teeth cnuplinga witliatarcamnctlnt shaft-Type,parameiere and slzeJI/T8821199 Jie standard defines the type, basic parameters and dimensions of type 1 intermediate disc gear coupling (hereinafter referred to as coupling). This standard is applicable to transmission systems that connect two non-directional shafts. The rotation diameter of the coupling end is 130~-1000mm. The nominal torque transmitted is G.3~3150kN·m. The angular offset when working load is 3”. When there is no working load, the directional offset is 5 pieces.
