Flexible pin gear coupling: 1.BL stick pin coupling: Scope of the stick pin coupling for connecting two coaxial drive shafts, two axes relative offset compensation and general damping performance. The working environment temperature of-20o ~ +70 oC. Does not apply to the site demanding the need to control and noise damping effect. 2.ZLL type - brake wheel with flexible pin gear coupling: ZLL - with brake wheel flexible pin gear coupling easy maintenance, longer life expectancy, remove the baffle can be replaced nylon Pin . The nylon pegs for a self-lubricating material, without lubrication, not only saves lubricant, and clean work environment. Pin gear coupling 3.ZL elastic column: basic parameters and the main dimensions of the use of a number of non-metallic materials Pin, placed in the the involution hole between the two coupling halves within the outer ring surface through studs transmitting torque to achieve coupling connection of two halves. the Plum coupling is a very common application of the coupling, also called a jaw coupling, is composed of two two metal claw plate and an elastic body. Two metal claw plate is generally steel No. 45, but is also useful in the case of requiring load sensitive aluminum alloy. Quincunx elastic coupling characteristics of the application, the superiority
