German ATN coupling, ATN model, ATN price

ATN coupling is a widely used type of coupling, also known as a jaw coupling, consisting of two metal jaw hubs and an elastomer. The two metal jaw hubs are typically made of 45 steel, but aluminum alloy is also used when load sensitivity is required.

ATN 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. Diaphragm couplings belong to the category of flexible couplings with metallic elastic elements; they rely on metallic diaphragms to connect the driving and driven machines to transmit torque, offering the advantages of elastic vibration damping, noise-free operation, and no need for lubrication, making them an ideal product to replace gear couplings and general couplings today. Main characteristics of diaphragm couplings: 1) Strong ability to compensate for misalignment between two shaft axes; compared with gear couplings, the allowable angular displacement is twice as large, the reaction force is small during radial displacement, flexibility is high, and certain axial, radial, and angular displacements are permitted. 2) Significant vibration damping effect, noise-free, and wear-free. 3) Suitable for operation in high temperatures (-80+300) and harsh environments, and can operate safely under conditions of impact and vibration. 4) High transmission efficiency, up to 99.86%. Particularly suitable for medium and high-speed high-power transmission. 5) Simple structure, light weight, compact size, and easy assembly and disassembly. Assembly and disassembly can be performed without moving the machine (referring to the type with an intermediate shaft), and no lubrication is required. 6) Can accurately transmit rotational speed without slip, suitable for transmission in precision machinery.

ATN 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, which generally prevents loosening or backlash between the diaphragm and the hubs. Some manufacturers offer two diaphragms, while others offer three diaphragms, with one or two rigid elements in the middle, connected to the hubs on both sides. 2) This characteristic of diaphragm couplings is somewhat 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, thus allowing it to withstand deviations of 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 that of 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 normal operating tolerance range of the coupling. 5) Adjust the model according to the shaft diameter: The initially selected dimensions for the bearing coupling connection, namely the shaft hole diameter d and shaft hole 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 the shaft diameters differ, the coupling model should be selected based on the larger shaft diameter. In newly designed transmission systems, the seven types of shaft holes specified in GBT3852 should be selected, with the J1 type shaft hole recommended to improve universality and interchangeability. Shaft hole length shall comply with the provisions of the i bearing coupling product standard.

ATN coupling abnormal noise troubleshooting

1) The gap between the two halves of the coupling is too wide, causing significant axial force on the diaphragm, leading to wear of the reamed holes or reamed bolts, resulting in abnormal noise; 2) Excessive axial misalignment or excessive angular misalignment between the two halves of the coupling can also cause vibration and abnormal noise during equipment operation; 3) Differences in speed between the driving and driven ends can also cause vibration and abnormal noise during equipment operation; 4) A fault in the motor's speed encoder disk causes the motor speed to fluctuate, leading to abnormal noise in the diaphragm coupling.
