The tire body of LA tire coupling is divided into two types: convex type and concave type. The convex type is divided into three types: integral type with skeleton, integral type without bone and radial cut type.Their common feature is that the tire ring is bolted to connect the two coupling halves to realize the connection of the two shafts.
The LAK saddle-shaped elastic coupling is composed of several saddle-shaped rubber blocks connected with the main and driven end half couplings through bolts to transmit torque. The structure is simple, the number of parts is small, the assembly and disassembly are convenient, and the maintenance is easy.
DL Polygonal Rubber Coupling is made of rubber material, made into a 6-corner (or octagonal) elastic piece with a circular cross-section, and a sleeve bonded with rubber after vulcanization is embedded in each place. The 8 (or 6) bolts passing through the sleeve are alternately connected with the flanges of the coupling half on the main and driven ends.
