The elastic pin tooth coupling has a certain compensation performance for the relative offset of the two shafts, suitable for medium and high power transmission, and not suitable for working parts that require vibration reduction and strict noise control.
The elastic column pin toothed coupling is a coupling that uses several non-metallic materials to make column pins, which are placed in the mating holes between the two halves of the coupling and the inner surface of the outer ring. The torque is transmitted through the column pins to achieve the connection between the two halves of the coupling. This coupling has the following characteristics: (1) The elastic column pin toothed coupling with brake wheel. The nylon column pin is a self-lubricating material that does not require lubrication, which not only saves lubricating oil but also purifies the working environment. (2) Compared with toothed couplings, the elastic column pin toothed coupling with brake wheels has a simpler structure, fewer components, and is easier to manufacture without the need for gear machining machines. (3) The toothed coupling with brake wheel elastic column pin is easy to maintain and has a long service life. The nylon column pin can be replaced by removing the gear plate. （4）The elastic column pin toothed coupling with brake wheels transmits large torque, and at the same torque, the rotation diameter is mostly smaller than that of the toothed coupling. It has a smaller volume and lighter weight, and can partially replace the toothed coupling.
