German Phoenix coupling Phoenix model Phoenix price

Phoenix coupling is a torsionally rigid coupling. It has no backlash even under load, and rigidly transmits torque even when misalignment generates loads. Lightweight, ultra-low inertia, and high sensitivity. Maintenance-free, with excellent oil resistance and corrosion resistance. Made of aluminum alloy and stainless steel. Available in set screw type, clamp type, and split type. Models with different bore sizes at both ends are also in stock.

Phoenix coupling features

Diaphragm couplings can compensate for axial, radial, and angular misalignments between the driving and driven machines caused by manufacturing errors, installation errors, load deformation, and temperature changes. As a flexible coupling with metallic elastic elements, the diaphragm coupling connects the driving and driven machines via metal diaphragms to transmit torque. It offers advantages such as elastic vibration damping, noiseless operation, and no need for lubrication, making it an ideal replacement for gear couplings and general couplings today. Main characteristics of diaphragm couplings: 1) Strong ability to compensate for shaft misalignment; compared to gear couplings, angular displacement can be twice as large, reaction force is small during radial displacement, flexibility is high, and certain axial, radial, and angular displacements are allowed. 2) Significant vibration damping effect, noiseless, and wear-free. 3) Suitable for high-temperature (-80+300) and harsh environments, and can operate safely under impact and vibration conditions. 4) High transmission efficiency, up to 99.86%. Particularly suitable for medium and high-speed high-power transmission. 5) Simple structure, lightweight, compact, and easy to assemble and disassemble. Can be assembled and disassembled without moving the machine (for types with an intermediate shaft), and requires no lubrication. 6) Accurately transmits rotational speed without slip, suitable for precision machinery transmission.

Phoenix coupling selection

Correct selection of diaphragm couplings: 1) A diaphragm coupling consists of at least one diaphragm and two hubs. The diaphragm is fastened to the hubs with pins, generally preventing loosening or rebound between the diaphragm and hubs. Some manufacturers offer two diaphragms, while others offer three, with one or two rigid elements in the middle connected to the hubs on both sides. 2) This characteristic is similar to bellows couplings; in fact, the torque transmission method of couplings is quite similar. The diaphragm itself is very thin, so it bends easily when relative displacement loads occur, allowing it to withstand misalignments up to 1.5 degrees while generating lower bearing loads in servo systems. 3) Diaphragm couplings are commonly used in servo systems. The diaphragm has good torsional rigidity, though slightly inferior to bellows couplings. 4) On the other hand, diaphragm couplings are very delicate and can be easily damaged if misused or incorrectly installed. Therefore, it is essential to ensure that misalignment remains within the allowable range for normal operation. 5) Adjust the model based on shaft diameter: The initially selected coupling connection dimensions, namely bore diameter d and bore length L, must meet the requirements of the driving and driven end shaft diameters; otherwise, the coupling specification must be adjusted according to the shaft diameter d. It is common for the driving and driven end shaft diameters to differ. When torque and speed are the same but shaft diameters differ, select the coupling model based on the larger shaft diameter. In newly designed transmission systems, select from the seven shaft hole types specified in GBT3852, recommending the J1 type shaft hole to improve universality and interchangeability. Shaft hole length shall comply with the i bearing coupling product standard.

Phoenix coupling usage precautions

1) Products with diaphragms have sharp edges that may cause injury; wearing thick gloves during installation is recommended. 2) Install protective covers or other devices around the coupling to ensure safety. 3) If shaft misalignment exceeds the allowable value during installation, the coupling may deform, leading to damage or shortened service life. 4) Allowable shaft misalignment for the coupling includes radial, angular, and axial deviations. During installation, adjust to ensure shaft misalignment is within the allowable values specified in the corresponding product catalog. 5) When multiple types of misalignment occur simultaneously, the corresponding allowable values must be halved. 6) To extend the service life of the coupling, it is recommended to keep shaft misalignment within 1/3 of the allowable value. 7) Tighten the screws after inserting the installation shaft; otherwise, the coupling may deform. Use a torque wrench when tightening screws, and do not use screws other than those provided. 8) If abnormal noises occur during operation, stop immediately and check installation accuracy, loose screws, etc. It is recommended to apply adhesive to the outer surface of the screws after installation and debugging to enhance protection.
