The coupling half is made of fine casting, cast iron HT20-40, cast steel ZG35Ⅱ, the shaft hole and keyway are drawn, and the column pin is made of MC nylon b. The elastic pin coupling is a pin made of non-metallic elastic material, which is placed in the flange holes of the two halves of the coupling, and the two halves of the coupling are connected through the pin. The structure of the coupling is simple. It is easy to manufacture, and it is more convenient to assemble, disassemble and replace the elastic element without moving the two halves of the coupling. The material of the elastic element (column pin) is generally nylon, which has the ability to compensate the offset of the two axes in a small amount. The elastic element is sheared during operation, and the work quality is relatively poor. It is only suitable for medium-speed transmission shafts with very low requirements, and is not applicable. It is suitable for working conditions with high requirements for work excellence.

Elastic Sleeve Pin Coupling Relies On The Locking Force Of Pin Group To Produce Friction Moment On The Contact Surface, And Compresses Rubber Elastic Sleeve To Transmit Torque. It Is Suitable For High Speed, Good Rigidity Of Mounting Base, High Accuracy Of Alignment, Small Impact Load And Low Requirement For Vibration Reduction Of Medium And Small Power Pumps. FCL type elastic sleeve pin coupling is in accordance with Japanese national standard JI1452, which is widely used and appreciated by customers in Japan and the world for its simple structure, convenient installation, small size, light weight, maintenance-free and reliable quality. FCL elastic sleeve pin coupling features: good vibration absorption, can make the drive shaft movement smoothly to the passive shaft. No axial thrust in transmission. Easy to disassemble and assemble, as long as the coupling bolts are removed, the connection between active and passive can be separated. If the relative displacement of two axes can be kept within the specified range after installation and adjustment, the coupling will have satisfactory service performance and long service life. Therefore, it can be widely used in various medium and small power transmission shafts driven by motors with small loads, such as reducer, transmission, pump, printing and dyeing machine, hoist, crane, compressor, conveyor, textile machine, hoist, ball mill and so on.

The function of a coupling is to connect two rotating shafts, for the transfer of rotary motion and torque. For a coupling to work at its optimum efficiency, it must match all required conditions, including performance, environmental, use and service factors. If all of these factors have been taken into consideration when selecting a coupling the coupling should have no failure issues over its lifetime. However, if just one of these factors is not met, a coupling can prematurely fail, causing anything from a small inconvenience, to a significant financial loss, and even the potential of personal injury.Get more news about Elastic Pin Coupling Wholesaler,you can vist our website!

1. Selecting the coupling too late in the design process
Couplings are often selected extremely late in the application design process, without meeting the complex requirements of the system. By considering couplings early on in the design process, each criteria can be considered individually, ensuring that the coupling chosen is suitable for the functions required.

2. Selecting the wrong type of coupling for the application
Several criteria must be considered when deciding on a type of coupling, including the type of application, torque, misalignment, stiffness, inertia, RPM, shaft mounting, environmental factors, space limitations, service factors, and cost. Each criteria must be individually considered to ensure that the coupling will be suitable for the application and not result in premature failure. This process of evaluation must also be repeated for any change in conditions throughout the application’s lifecycle.

3. Selecting the wrong type of coupling for the application misalignment conditions
An essential consideration when selecting a coupling is the misalignment conditions of the application. This may be angular, parallel or axial, or a combination of more than one misalignment (complex misalignment). Flexible couplings should be considered in these conditions, although the type will depend on the type of misalignment present. For example, an oldham coupling is suitable for large amounts of parallel misalignment, but cannot tolerate a high level of angular or axial misalignment, whilst a single beam coupling can withstand large amounts of angular and axial misalignment, but not parallel.

4. Failure to correct excessive misalignment
Even flexible couplings which are designed for use on misaligned shafts have their limits. A common point of failure is the under-estimation of the degree of misalignment, creating loads that surpass the coupling specifications. This causes the coupling to wear at an accelerated rate, and has the potential to cause other components, such as bearings, to also fail prematurely. Where misalignment exists beyond the manufacturer specifications for the coupling, this should first be rectified with shaft realignment before installing the coupling.

5. Selecting the wrong coupling for the torque in the application
The torque of an application is frequently under-estimated. The maximum instantaneous torque for the application needs to be considered, in addition to the steady state torque. Flexible couplings have different static torque ratings depending on the design type. For example, a double disc coupling will typically offer a 15-20% higher static torque rating than an identically sized Oldham coupling with an acetal disc.

6. Lack of consideration for windup
Windup is also known as torsional compliance or torsional rigidity, and is present in all couplings. It is the rotational deflection between the driver and the load, similar to winding up a spring. The most significant problem with this is maintaining accuracy of location due to a difference in angular displacement from one end of the coupling to the other.

7. Lack of consideration for backlash
Backlash is the loss of motion momentarily in a coupling. For example, when torsion is applied in one direction, the coupling bends and compresses under that stress. When the direction of torsion is changed, backlash is experience within the coupling. Any amount of backlash in a motion control application could be detrimental to the application, potentially causing lack of accuracy in positioning, and difficulty in tuning the system. Zero backlash couplings should be considered in these scenarios.

8. Selecting a coupling with the wrong amount of dampening
Dampening refers to the minimisation of shock and vibration and is particularly important in motion control and power transmission applications to reduce the waste of energy and the unnecessary stress on system components. Shock dampening helps to reduce the effects of impulse loads, minimising shock to the motor and other sensitive equipment. The potential for premature coupling failure can be accelerated when the selection of coupling type does not fully take into consideration the dampening levels required.

The FCL elastic sleeve pin coupling has a simple structure, is easy to make, does not need lubricating oil, does not need to be bonded with metal vulcanization, and is convenient to change the elastic sleeve, does not need to move the half coupling, and has the performance of repaying the relative deviation of the two shafts and reducing vibration and mitigating conflicts. The elastic sleeve office is a compression deformation. Because the elastic sleeve is thin, small in size and limited in elastic deformation, the elastic sleeve pin coupling can repay the axial displacement and elasticity, but the allowable compensation amount for axial displacement is small and the elasticity is weak.

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