FCL type flexible sleeve column pin coupling is characterized by simple structure


FCL type elastic sleeve pin coupling is characterized by simple structure, convenient installation, easy replacement, small size and light weight, so it is widely used. If the relative displacement of the two shafts can be maintained within the specified range after installation and adjustment, the coupling The shaft will have satisfactory performance and long working life. Therefore, it can be widely used in various medium and small power transmission shaft systems driven by electric motors with small loads, such as reducers, cranes, compressors, conveyors, textile machines, hoists, ball mills, etc.

The FCL type elastic sleeve pin coupling is relatively simple in structure, easy to manufacture, does not need lubricating oil, does not need to be bonded with metal vulcanization, is convenient to change the elastic sleeve, does not need to move the half coupling, and has the ability to compensate for the relative offset of the two axes and reduce vibration. conflict performance. The elastic sleeve is a compression variant, because the thickness of the elastic sleeve is thin, the size is small, and the elastic deformation is limited. Therefore, although the elastic sleeve pin coupling can compensate for the axial displacement and elasticity, the allowable compensation for the axial displacement is less. The elasticity is weak.

The FCL type elastic sleeve pin coupling is the friction moment generated on the contact surface by the locking force of the pin group, and compresses the rubber elastic sleeve to transmit the torque. It is suitable for medium and small power shafting transmission with good mounting base rigidity, high alignment, half-large impact load, and low vibration damping requirements.

The reasons for the less allowable compensation for the axial displacement of the FCL type elastic sleeve pin coupling are as follows:

1. The FCL type elastic sleeve pin coupling relies on the locking force of the pin group to generate the friction torque on the contact surface, and compresses the rubber elastic sleeve to transmit the torque. It is suitable for small and medium power shafting transmission with good mounting base rigidity, high centering accuracy, small impact load and low vibration damping requirements.

2. The elastic sleeve is subject to compression deformation. Due to the thin thickness, small volume and limited elastic deformation of the elastic sleeve, although the elastic sleeve pin coupling can compensate for the axial displacement and elasticity, the allowable compensation amount for the axial displacement is relatively small. less, less elastic.​​

3. The FCL type elastic sleeve pin coupling is relatively simple in structure, easy to manufacture, does not require lubrication, does not need to be bonded with metal vulcanization, and is convenient to replace the elastic sleeve without moving the half coupling. Vibration damping performance.

Permissible relative displacement of elastic sleeve pin coupling:
Radial displacement: 0.2~0.6mm Angular displacement: 0°30′~1°30′.
