In high-speed and heavy-load power transmission, some couplings also play the role of buffering, vibration reduction, and improving the dynamic performance of the shaft system. The coupling consists of two halves, which are connected to the driving shaft and the driven shaft respectively. Generally, most power machines are connected to working machines by means of couplings. If there is an error in the installation, it is easy to scratch the inner wall of the cylinder or cause air leakage, so use Floating joint is actually equivalent to a coupling.
Main features of cylinder floating joint:
1. Easy to install;
2. Eliminate the interference phenomenon caused by connection errors between the two axes;
3. The processing accuracy of matching parts can be appropriately enlarged;
4. Meet the requirements of small size, high tensile and compressive strength;
5. It is used to reduce errors, protect related components, make the equipment run smoothly, and extend the service life of the equipment.
How the cylinder floating joint works: If the diameter of the cylinder is installed on the moving object, "piston rod bending", "rod bearing and rod seal wear" may occur due to "eccentricity", "poor balance accuracy" and other reasons, which will reduce the performance of the cylinder , shorten the service life of the cylinder. Floating coupling is the solution to the eccentricity problem in the future and isThe cylinder operates smoothly, and the floating coupling has been lubricated, so no additional oil is needed. The cylinder floating joint absorbs the eccentricity and lack of parallel accuracy of the connecting piece and the cylinder, so that the cylinder and the connecting piece can work within the allowable eccentricity range. It is used in the floating joint assembly so that centering and final fine adjustments are not necessary when the cylinder is installed. Eliminating the interference phenomenon caused by the connection error between the two axes can appropriately amplify the processing accuracy of the mating parts. In line with the requirements of small size, high resistance and compressive strength, a floating coupling is needed at this time, precisely to solve the problem of eccentricity and make the cylinder move smoothly. The floating coupling is full of lubricant and does not require additional oil.
