 1.BL stick pin coupling: the scope of application of the stick pin coupling joins two coaxial drive shafts, with a certain degree of compensation of the two axes relative offset and damping performance. Operating ambient temperature of-20o ~ +70 oC. Does not apply to the site of demanding and need to control the noise damping effect. 

 2.ZLL type - brake wheel coupling of the flexible pin teeth: ZLL type - with easy maintenance of brake wheel flexible pin gear coupling, longer life expectancy, remove the bezel to replace the nylon dowel pin. Nylon dowel pin for the self-lubricating material, without lubrication, not only saves oil, and clean work environment. 

 Pin gear coupling 3.ZL type of flexibility: the basic parameters and dimensions used a number of non-metallic materials, pins, placed in between the two halves of the coupling and outer and inner surface of the co-Kong, through pin transmitting torque to the coupling halves join. 
 Plum coupling is a very common coupling, also known as the claw coupling, the two metal claw plate and an elastomer composition. Two metal claw plate is generally 45 steel, but the requirements of load-sensitive aluminum alloys. Of cinquefoil flexible coupling in the application characteristics, the superiority of
