This standard specifies the type, basic parameter and main dimension of LX and LXZ pin coupling elastomer (hereinafter referred to as "coupling") and provides the technical requirements, inspection rules, marking, packing and storage.
For the purposes of this standard, the said gear 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: -20℃~+70℃ and transmission nominal torque 250N?m~180,000N?m.
