DSM 16.1 coupling

DSM 16.1 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 are flexible couplings with metallic elastic elements. They rely on metal diaphragms to connect the driving and driven machines to transmit torque, offering advantages such as elastic vibration damping, noise-free operation, and no need for lubrication. They are ideal products for replacing gear couplings and general couplings today. Main characteristics of diaphragm couplings: 1) Strong ability to compensate for misalignment between two shafts; compared with 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, noise-free, and wear-free. 3) Suitable for operation in high temperatures (-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, light weight, compact size, and easy assembly and disassembly. Can be assembled and disassembled without moving the machine (referring to the type with an intermediate shaft), and requires no lubrication. 6) Can accurately transmit rotational speed without slip, suitable for transmission in precision machinery.

DSM 16.1 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 and generally does not loosen or cause 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 similar. The diaphragm itself is very thin, so it bends easily when relative displacement loads occur, 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 stiffness, but slightly less than 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 coupling connection dimensions, 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 specifications 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, with the J1 type shaft hole recommended to improve universality and interchangeability. Shaft hole length shall comply with the i bearing coupling product standard.
