Scope

This Standard specifies the structural types, basic parameters, main dimensions, marking method, technical requirements and inspection rules of the standard LT type and LTZ type elastic sleeve pin couplings (hereinafter referred to as the coupling).
This Standard is applicable to the driving shaft system connecting the two coaxial lines with transmission nominal torque of 16N·m~ 22 400N·m at working temperature of 30°C~ +100°C, and has the function of compensating the relative displacement of the two axes and buffering the axes.
