High Quality JSB Type Serpentine Spring Shaft Snake Grid Flexible Coupling Grid Shaft Steel Coupling
Description:
JSB type serpentine spring coupling is referred to as "snake spring coupling" according to JB/T 8869-2000 standard. Unlike JS type serpentine spring coupling, JS type serpentine spring coupling is used for horizontal installation. The JSB type serpentine spring coupling is used for vertical installation.
JSB type serpentine spring coupling is suitable for working conditions such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive medium, salt water, radiation and other working conditions. For the working quality of high temperature, low temperature, oil, acid and alkali medium, it is not suitable to use flexible coupling with general rubber as elastic material. The flexible coupling of metal elastic component, such as diaphragm coupling, should be selected. Serpentine spring couplings, etc.
JSB type serpentine spring coupling is mainly used in crusher, crank reciprocating, reducer, metallurgy, mine, crane and other equipment. It has a certain medium and high power transmission shaft system connecting two coaxial lines. It compensates the relative offset and damping and buffering performance of the two axes. The working temperature is -30°C~+150°C, and the nominal torque is 45~800000N.m.
Features:
1. Specially designed for servo, stepper motor.
2. The shaft and the shaft sleeve are connected without clearance, which is suitable for forward and reverse rotation.
3. Low inertia, suitable for high speed running.
4. The diaphragm is made of stainless steel, with excellent fatigue resistance.
5. Clamping screw fastening method.
6. The shaft sleeve is made of high-strength aluminum alloy.
Parameters:
Advantages:
1. Good vibration reduction and long service life
The coupling is axially embedded in the two halves by more than 36% of the serpentine spring. The trapezoidal cross-section serpentine spring piece is made of high-quality spring steel, which has undergone strict heat treatment and is specially processed. It has good mechanical properties, so that the service life of the coupling is much longer than that of non-metal elastic element Column pin coupling, nylon rod pin coupling) greatly increased.
2. Wide range of variable loads and safe starting
The tooth surfaces where the two half-couplings contact the reed are arc-shaped. When the transmission torque increases, the spring leaf will deform along the tooth arc surface, so that the force points of the two half-couplings acting on the reed are close. The contact point between the reed and the tooth surface, that is, the change of the torque, changes with the magnitude of the transmitted torque, and its transmission characteristics are variable stiffness. Therefore, it has a greater load variation than ordinary elastic couplings. The buffer effect produced when the transmission force makes the reed deform along the tooth arc, especially when the machine is started or when a strong impact load occurs, can protect the safety of the supporting parts to a certain extent.
3. High transmission efficiency and reliable operation
The transmission efficiency of the coupling has been determined to reach 99.47%, and its short-term overload capacity is twice the rated torque, and the operation is safe and reliable.
4. Low noise and good lubrication
The aluminum alloy casing protects the spring from being thrown out during operation, and the casing is filled with butter, which not only ensures good lubrication, but also eliminates the noise when the reeds engage by being absorbed by the grease damping.
5. Simple structure, easy assembly and disassembly
The whole machine has few parts, small size, and light weight. The spring piece designed as a trapezoidal cross-section fits the trapezoidal tooth groove very conveniently and tightly, so that the assembly, disassembly and maintenance are easier than ordinary couplings.
6. Large installation deviation is allowed
Since the spring piece is in point contact with the arc surface of the tooth, the coupling can obtain greater flexibility. It can be installed to work normally with radial, angular and axial deviations at the same time.
