LTZ (formerly TLL) type elastic sleeve pin coupling with brake wheel has a relatively simple structure, easy manufacturing, no lubrication, no need for metal vulcanization bonding, easy replacement of elastic sleeve, no need to move half coupling, and has certain compensation for relative offset of two shafts and vibration reduction and buffering performance. The elastic sleeve works by being compressed and deformed. Since the elastic sleeve is thin, small in size, and has limited elastic deformation, the elastic sleeve pin coupling can compensate for axis displacement and elasticity, but the allowable compensation for axis displacement is small and the elasticity is weak.
