Some types of gear couplings in my country

When the gear coupling is working, the two shafts produce relative displacement, and the tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power loss. Therefore, the gear coupling needs to be well lubricated and sealed. Work in the state.Gear couplings have small radial dimensions, large carrying capacity, and are long used for shaft transmission under low-speed and heavy-duty conditions. High-precision and dynamically balanced gear couplings can be used for high-speed transmission, such as the shaft of dyeing steam turbines. Transmission line.Because the angular compensation of drum gear couplings is greater than that of straight gear couplings, drum gear couplings are widely used at home and abroad. Straight gear couplings are obsolete products, and those who choose should try not to Optional.The different types of gear couplings formulated as machinery industry standards in my country are all drum gear couplings, with the following types: GICL type-wide basic type (JB/T8854.2-1999)
