Elastic pin coupling has the limited ability of relative displacement compensation, simple structure and it is easy to manufacture. It doesn’t need to move half coupling when change the cylindrical pin. The cylindrical pin will under the role of shear force when in the work which determines the working reliability, so the pin coupling is not suitable for high working reliability requirements, the low-speed and heavy-load or strong shock and vibration transmission shafting working condition, except for the small and medium drive shaft.
Machined all over, good dynamic characteristics
Hub material steel for higher loads and speeds
The material of elastic components is linen so it has high hardness and resistance to wear and apply for the circumstance with causticity
Circle surface of metal brake ring operated by quenching
