When lubricating, replace the grease in the Curved-tooth Gear Coupling, and remove the grease fitting 180 degrees from the fitting used for filling the pipe joint. Pump in fresh grease until the grease starts to drain from the opening. Once it is confirmed that the pipe joint has been filled, replace it with a different grease fitting or the plug has been removed and properly tightened. The load category of the transmission system is the basic basis for selecting the type of Curved-tooth Gear Coupling. For the working load with large changes in impact, vibration and torque, the flexible Curved-tooth Gear Coupling with elastic elements, namely the elastic Curved-tooth Gear Coupling, should be selected to cushion, reduce vibration, compensate the shaft line offset and improve the working performance of the transmission system.
The torque during frequent forward and reverse rotation and braking is several times of the torque during normal balanced operation. It is overload operation, which shortens the service life of the elastic element of the Curved-tooth Gear Coupling. The Curved-tooth Gear Coupling is allowed to overload for a short time, and the general short time load shall not be greater than 2~3 times of the nominal torque. The power of the power machine is the main basis for determining the size of the Curved-tooth Gear Coupling, and is proportional to the torque of the Curved-tooth Gear Coupling. From the power machine to work, the main and driven ends are connected by one or several Curved-tooth Gear Couplings of different varieties or different types and specifications to form a shafting transmission system. In mechanical transmission, power machine is nothing more than electric motor, internal combustion engine and steam turbine.
Due to the different working principles and structures of power machines, their mechanical characteristics vary greatly. Some operate smoothly and some have impact during operation, which has different effects on the transmission system. The drum-shaped gear coupling has the general damping and two-axis offset compensation ability, and should be used in situations where the forward and reverse directions are changeable and the starting is frequent. The Curved-tooth Gear Coupling is applicable to the coaxial transmission shaft system. It uses the cross section shear strength of nylon rod to transmit torque, and has the ability to compensate shaft offset. The pin in the Curved-tooth Gear Coupling shaft is in shear and extrusion state when working, and its strength condition is to calculate the shear strength on the cross section of the elastic pin and the extrusion strength between the pin and the pin hole wall.
