Scope

Main Technical Content: 3. Terminology and Definitions The terms and definitions defined in GB/T 3931 "Coupling Terminology" apply to this document. 3.1 Serpentine Spring Couplings Serpentine spring couplings are an advanced structural shaft connection component. They consist of two hubs, two half-shields, two sealing rings, and serpentine springs. The coupling achieves the connection between the driving shaft and the driven shaft by embedding serpentine spring blades into the teeth grooves of the two hubs. During operation, the driving end teeth engage with the spring blades to transmit torque. The elastic deformation generated by the spring blades during torque transmission enables the mechanical system to achieve better vibration reduction effects. 3.2 Hydraulic Quick-Disassembling Serpentine Spring Couplings A type of coupling that uses hydraulic technology to connect shafts and hubs without the need for heating. It enables cold disassembly and assembly, avoiding fire safety requirements in special environments. The shaft and hub are assembled with a clearance fit, and the oil injection and pressure testing can be completed within 15 minutes on-site, allowing for quick disassembly and assembly. It also retains all the functions and advantages of serpentine spring couplings. 4. Classification 4.1 Types 4.2 Models and Markings 5. Structural Types, Basic Parameters, and Main Dimensions 6.
