The snake spring coupling is a kind of advanced metal elastic coupling. It delivers torque by a snake-shaped spring.
Its transmission characteristics and advantages are as follows:
1. Good vibration resistance. Long service life couplings are embedded more than two and a half 36 percent in the shaft of the snake-shaped spring. Trapezoidal cross-section of coil spring is made of high quality spring steel, the strict heat treatment, and special processing and become, has the good mechanical properties, which makes the service life of the coupling than non-metallic elastic element coupling (such as elastic dowel pin, nylon rods pin coupling) increase greatly.
2, under variable load range is big, starting safety of two and a half couplings and reed contact tooth surface is curved, when the torque is increased, leaf spring deformation along the tooth surface, make two and a half point close to the coupling effect on the reed. The contact point of the reed and the tooth surface is the change of torque, which varies with the transmission torque, and its transmission property is variable stiffness. Therefore, it has more load variation than the general elastic coupling. From the image below shows, the momentum to make reed along the arc tooth deformation produced by the buffer role, especially, when the machine is starting or strong impact load to a certain extent, to protect the safety of the supporting parts.
3. The transmission efficiency of the transmission efficiency is high, and the transmission efficiency of the reliable coupler can be measured by 99.47%, and its short-term overload capacity is twice as high as the rated torque, and the operation is safe and reliable.
4, low noise, good lubrication aluminum alloy cover to protect the spring to avoid running when thrown outwards, and casing filled with butter, not only make good lubrication, and make the reed meshing noise is butter damping absorption and elimination.
5, simple structure, convenient installation the machine parts, small volume, light weight, is designed to be trapezoidal section leaf spring with trapezoidal alveolar is particularly convenient, close together, so that the installation, maintenance easy coupling than normal.
6. It is permissible to have a larger installation bias because the spring and tooth arc are touched, so that the coupling can get a greater flexibility. It can be installed at the same time with radial, angular, axial deviation and normal work.
Application scope:
1, snake-like spring coupling is suitable for connecting two coaxial line, high-power transmission shafting, has certain two axes relative offset compensation and vibration reduction and buffer performance, working temperature of 30 ℃ ~ + 150 ℃, passing nominal torque 45 ~ 800000 n. m.
2. The coupling of the snake spring couplings is mainly applied to the rock crusher, reciprocating movement of crank, reducer, metallurgy, mining, lifting machinery and so on.
3. The shaft transmission of other mechanical and equipment of the snake-shaped spring coupler, where the motor is connected to the member, the motor is connected with the reducer box or the shaft and the shaft.
