Does flexible coupling need to lubricate?

Flexible coupling is used to connect two shafts of different machines. Flexible coupling is a mechanical part that allows the machine to rotate together to transmit torque, which is a more critical part. So now we briefly introduce to you about improving the lubrication conditions of the flexible coupling so that its performance becomes more excellent.

Does flexible coupling need to lubricate?

Yes! Flexible couplings need to be lubricated with grease, and the boot prevents dust and sand from splashing into the joints to damage their lubrication. Flexible couplings require regular maintenance, replace special grease, check for cracked boots, and loose clamps.

On the one hand, flexible coupling is objective and bears natural wear. Because the flexible coupling and the drive shaft are assembled to transfer torque in a working environment with high speed and force. The parts are inevitably worn, which is objective

On the other hand, factors such as human factors, driving technique, and maintenance, fail to follow operating procedures, rude behavior, lack of timely maintenance, and increased damage to parts of flexible couplings.

If the chassis makes an unbroken “snap” sound when the vehicle is moving when it suddenly increases, decelerates, or steers, the flexible coupling may be running out of oil or damaged.

In addition to the flexible coupling applied to the driving system, the steering column of the steering system applies the universal joints to transfer steering forces between shafts with varying shaft lines. For ease of removal and installation, tools such as universal joints and spark plug wrenches are also applied to universal joints.

 

How to lubricate flexible coupling?

The lubrication of flexible coupling uses high-quality grease, which is compatible with flexible coupling in the same life span. And the flexible coupling of some commercial transportation vehicles, especially the existing old trucks, are still repairable.

To protect the flexible coupling from wear, the operator must:

  • According to the type, speed and size of the flexible coupling, select the appropriate grease.

  • Install a properly selected flexible coupling within the allowable deviation range, larger torque and continuous torque conditions.

  • Regularly check the equipment for leakage of lubricating oil seals, keyways, packing plugs and flange couplings; missing or loose bolts, and vibration, and regularly readjust the equipment.

  • Determine the appropriate amount of lubrication and the frequency of equipment inspection.

  • Finally, when relubricating the flexible coupling, the operator should completely disassemble the flexible coupling regularly for visual inspection and thorough cleaning

Some people use 2# extreme pressure lithium complex grease, which is based on two points. First, its fluidity is better, so that it can easily reach the lubrication part. Second, the grease has good extreme pressure resistance and is suitable for working conditions of flexible coupling.

 

How to maintain flexible coupling when it cannot be lubricated?

Flexible coupling is a transmission output shaft and final drive input shaft in different straight lines. Even if the angle and distance between the two shafts change, power can be transmitted.

In the maintenance of the flexible coupling, it is very important to ensure the lubrication of the flexible coupling that the amount of oil injection must be reasonable within the possible range. The fueling hole is blocked, the grease nipple is smashed into the hexagonal deformation or the grease nipple is rusted, the oil circuit will be blocked so that the grease nipple should be replaced in time. During the replacement process, keep the area around the interface clean. It is necessary to prevent the mixing of impurities, dust and sand in the machine.

The intake pressure of the grease gun is insufficient. The high-pressure oil injector is an oil injection device powered by compressed air. The function of pump is to produce high pressure by oil, and then the high pressure is used for oil injection. Pay attention to starting the air compressor before using, and prepare compressed air of about 0.6 MPa. The working principle of refilling grease which is not suitable for lubricating grease is that the thickening agent keeps the oil in the position, where needs lubrication. When there is a load, the thickening agent can release the oil to play a lubricating effect.

The flexible coupling is a special coupling. Due to its structural characteristics, the driving shaft and the driven shaft are not on the same axis. When there is an angle between the axes, the connected two shafts can rotate continuously, and reliably transmit torque and movement.
