JB/T 7849-2007 (English Version) PDF

Scope: This standard specifies the type, basic parameters, main dimensions, technical requirements, inspection rules and markings, packaging and storage of radial elastic pin couplings (hereinafter referred to as couplings). The coupling specified in this standard is mainly suitable for connecting two coaxial transmission shafts. It has certain radial, axial and angular displacement compensation and shock absorption and buffering properties. The operating temperature is -35℃～+ 80℃, the nominal transmission torque is 1250N·m～355000N·m
