Some types of toothed couplings in China

When the toothed coupling is working, the two shafts produce relative displacement, and the tooth surfaces of the internal and external teeth make periodic axial relative sliding, which will inevitably form tooth surface wear and power loss. Therefore, the toothed coupling needs to work under the condition of good lubrication and sealing. The gear coupling has small radial size and large bearing capacity. It is used for shafting transmission under low-speed and heavy-duty working conditions. The gear coupling with high precision and dynamic balance can be used for high-speed transmission, such as shafting transmission of dye turbine. Because the angular compensation of drum gear coupling is greater than that of straight gear coupling, drum gear coupling is widely used at home and abroad. Straight gear coupling is an obsolete product, and the user should try not to use it. Different types of gear couplings formulated as mechanical industry standards in China are drum gear couplings, including the following types: GICL type - wide basic type (JB / t8854.2-1999)
Giicl type - narrow basic type (JB / t8854.2-1999)
Intermediate shaft type (cl54.88z-t54.883)
Giiclz type - narrow intermediate shaft type (JB / t8854.3-1999)
Gcld type - connected to motor shaft extension type (JB / t8854.1-1999)
WGP type - type with brake disc (JB / t7001-93)
WGC type - vertical installation type (JB / t7002-93)
Wgz type - type with brake wheel (JB / t7003-93)
WGT type - intermediate sleeve type (JB / t7004-93)
TGL type - nylon inner ring gear type (JB / t5514-91)
WGJ type - connected to intermediate shaft type (JB / t8821-1998)
Ngcl type - type with brake wheel (JB / zq4644-97)
Ngclz type - type with brake wheel (JB / zq4186-97)
