Flexible Jaw Coupling

Flexible Jaw Coupling :

Coupling function 

It is used to connect the two shafts together. The two shafts cannot be separated when the machine is running. The two shafts can be separated only after the machine stops and the connection is disassembled. 

Type of coupling 

The relative position of the two shafts connected by the coupling will change due to manufacturing and installation errors, deformation after bearing and the influence of temperature change, which often can not ensure strict alignment. According to whether the coupling has elastic elements, whether it can compensate various relative displacements, that is, whether it can maintain the connection function under the condition of relative displacement and the purpose of the coupling, the coupling can be divided into rigid coupling, flexible coupling and safety coupling 

Flexible jaw coupling with elastic elements, which can transmit motion and torque; It has different degrees of axial, radial and angular compensation performance; It also has different degrees of vibration damping and cushioning effects to improve the working performance of the transmission system, including various non-metallic elastic element flexible couplings and metal elastic element flexible couplings. Various elastic couplings have different structures and different functions in the transmission system

Plum blossom elastic coupling is mainly applicable to the working occasions with frequent starting, positive and reverse rotation, medium high speed, medium torque and high reliability requirements, such as metallurgy, mining, petroleum, chemical, lifting, transportation, light industry, textile, water pump, fan, etc. The working environment temperature is - 35 ℃～+80 ℃, the transmission nominal torque is 25 ～ 12500Nm, and the allowable speed is 1500 ～ 15300r/min.

The quincunx elastic coupling is mainly composed of two convex teeth closely engaged and subjected to radial extrusion to transmit torque. When the two axes are relatively offset, the elastic element will have corresponding elastic deformation and play an automatic compensation role.

The flexible jaw coupling has the following characteristics:

1. The coupling needs no lubrication, is convenient for maintenance and has less workload, and can operate continuously for a long time.

2. High strength polyurethane elastic element is wear-resistant and oil resistant, with large bearing capacity, long service life, safety and reliability.

3. It is stable and reliable, with good vibration damping, buffering and electrical insulation performance.

4. It has greater axial, radial and angular compensation capacity.

5. Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions.
