Snake spring coupling
Snake spring coupling is a tool that bears a large torque and is suitable for heavy machinery and general machinery occasions.
Features of Snake Spring Coupling:
1. The characteristics of the snake spring coupling: the snake spring coupling uses a snake spring as the elastic element. It has strong elasticity while increasing the transmission torque of the snake spring coupling. It is widely used in heavy machinery and general purpose This kind of serpentine spring that passes through the process on mechanical occasions has a long service life, allows high speed, and has good compensation capabilities in the axial, radial and angular directions.
Snake spring coupling can withstand large torque, suitable for heavy machinery and general machinery occasions
2.联轴器弹簧又名蛇形弹簧。蛇簧联轴器扭短范围为26-270000N.M。两半轴允许相对径向位移0.5-3mm，轴向位移4-20mm,角位移1o15’。
3. Pass, start.The transmission efficiency can reach 99.47%, and the short-term overload capacity is twice the rated torque...;
4. Simple structure; convenient disassembly and assembly, long service life;
5. Good damping effect, avoiding resonance.
Snake spring coupling is a structured metal elastic coupling.It relies on serpentine springs to transmit torque.Its transmission characteristics and advantages are as follows:
1. Good vibration damping and long service life. The coupling is axially embedded in the two halves with a serpentine spring leaf for more than 36%.The serpentine spring sheet with trapezoidal section adoptsSpring steel, after rigorous heat treatment and processing, has good mechanical properties, so that the service life of the coupling is much longer than that of the non-metal elastic element coupling (such as elastic sleeve pin, nylon rod pin coupling) Great growth.
2. Large range of bearing variable load, starting, The tooth surfaces of the two half couplings in contact with the reeds are arc-shaped. When the transmission torque increases, the springs will deform along the tooth arcs, so that the force points of the two half couplings on the reeds are close.The contact point between the reed and the tooth surface, that is, the change of torque, changes with the size of the transmitted torque, and its transmission characteristics are variable stiffness.Therefore, it has a load variation that can withstand a general elastic coupling.The buffering effect produced by the transmission force when the reed deforms along the tooth arc, especially when the machine is started or impact load, to a certain extent to protect the supporting partsSex.
3. Transmission, operation, the transmission efficiency of the coupling is determined to reach 99.47%, and its short-term overload capacity is twice the rated torque..
4. Low noise, lubricate the aluminum alloy casing to protect the spring from being thrown out during operation, and the casing is filled with butter, which not only makes the lubrication good, but also makes the noise of the reed meshing is absorbed by the butter damping.
5. Simple structure, convenient assembly and disassembly. The whole machine has few parts, small size and light weight. The spring leaf designed as a trapezoidal section and the trapezoidal tooth groove are particularly convenient and close, so that assembly and disassembly and maintenance are easier than ordinary couplings. .
6. Larger installation deviation is allowed. Because the spring leaf and the tooth arc surface are in point contact, the coupling can obtain greater flexibility.It can be installed to work normally under conditions of radial, angular and axial deviations at the same time.
