1 Scope
This standard specifies the type and parameters, technical requirements, test methods, inspection rules, marking, packing and storage of Type LM, LMD, LMS, LMZ-I and LMZ-II coupling with elastic spider (hereinafter referred to as "coupling").
For the purposes of this standard, the said coupling is applicable to coupling the transmission shafting of two coaxial lines, and functions as two-shaft relative displacement compensation and general vibration reduction. Its working temperature: -35℃~+80℃ and transmission nominal torque 16N•m~25000N•mV.
