Serpentine Spring Coupling

Serpentine spring coupling is a shaft connection transmission component with advanced structure, which mainly relies on serpentine spring sheets to transmit torque. ‌ This coupling has a high vibration reduction effect, with a vibration reduction rate of more than 36%, and a transmission efficiency of up to 99.47%. It is suitable for heavy machinery and general machinery occasions, can withstand large torque, and has good compensation capabilities in axial, radial and angular directions. ‌

Main features:

1. High torque transmission capacity: The serpentine spring coupling uses serpentine springs as elastic elements, has strong elasticity and high stiffness, and can effectively transmit large torque. Its wide torque range can meet the needs of various occasions such as heavy machinery and general machinery, such as metallurgy, mining, lifting machinery and other industries. ‌

2. High transmission efficiency: The transmission efficiency of the serpentine spring coupling can reach 99.47%, and the energy loss is small when transmitting power. It can effectively transmit power from the driving shaft to the driven shaft, improving the working efficiency of the equipment. ‌

Uses:

1. Heavy machinery: such as large crushers, ball mills, mixers and other heavy machinery. These equipment need to transmit large torques. The serpentine spring coupling can meet the high requirements of these equipment for power transmission.

2. General machinery: including compressors, fans, pumps and other equipment. These equipment will generate vibration and displacement during operation. The serpentine spring coupling can adapt to these working characteristics and ensure the stable operation of the equipment.

3. Other equipment: such as printing machinery, papermaking machinery, plastic machinery, etc. These equipment have high requirements for the vibration reduction effect and transmission accuracy of the coupling. The serpentine spring coupling can meet these requirements.

Application scenarios:

1. It is suitable for connecting medium and high power transmission shaft systems of two coaxial lines. It has certain compensation for the relative offset of the two shafts and vibration reduction and buffering performance. The working temperature is -30~+150, and the nominal torque transmitted is 45~800000N.m.

2. It is mainly used in crushers, crank reciprocating motion, reducers, metallurgy, mining, lifting machinery, etc.

Product advantages:

1. Good vibration reduction effect: During operation, the spring will produce elastic deformation when transmitting torque. This elastic variable can enable the mechanical system to obtain a better vibration reduction effect, and the average vibration reduction rate can reach more than 36%. In addition, the serpentine spring coupling can play a certain buffering role and protect the supporting parts when the machine starts or is subjected to a strong impact load.

2. Strong compensation ability: The serpentine spring coupling has good axial, radial and angular compensation capabilities. The axial displacement can reach 4-20mm, the radial displacement can reach 0.5-3mm, and the angular displacement can reach 1°15′, which can adapt to the displacement deviation of the shaft caused by thermal expansion and contraction during operation.

3. High reliability: Its structural design is reasonable, with variable stiffness transmission characteristics, can withstand large load changes, and has a short-term overload capacity, generally twice the rated torque, and is safe and reliable in operation. The spring is made of high-quality spring steel, strictly heat treated and specially processed, with good mechanical properties and fatigue life, and a long service life.

4. Low noise: The aluminum alloy cover of the coupling can protect the spring from being thrown out during operation, and the housing is filled with butter, which not only makes the lubrication good, but also eliminates the noise when the spring is meshed by the butter damping, which can reduce the noise during the operation of the equipment.

5. Simple structure and convenient assembly and disassembly: The whole machine has few parts, small size, light weight, and the spring leaf designed with a trapezoidal cross-section is convenient and tight to fit the trapezoidal tooth groove, making assembly and maintenance easier than general couplings.

6. Wide range of applications: It is suitable for connecting medium and high power transmission shaft systems of two coaxial lines. The operating temperature range is -30℃~+150℃, which can meet the requirements of a variety of different working environments.

Application areas:

Widely used in smelting, steel rolling, heavy machinery, steam turbines, petrochemical industry, ships and other industries.
