German Sauter Feinmechanik coupling, Sauter Feinmechanik model, Sauter Feinmechanik price

Sauter Feinmechanik couplings are divided into two main categories: convex and concave. The convex type is further divided into three types: integral with skeleton, integral without skeleton, and radial slit. The inner side of the tire ring is bonded to the steel skeleton by vulcanization, and nuts are welded at the bolt holes on the skeleton. During assembly, bolts are used to connect the flanges of the two coupling halves. Torque is transmitted by the friction generated between the tire and the flange end faces when the bolts are tightened. The tire ring undergoes torsional shear deformation during operation, so the tire coupling has high elasticity, a large capacity to compensate for relative displacement between the two shafts, and good damping. It also features a simple structure, requires no lubrication, and is convenient to install, disassemble, and maintain. Its disadvantages include low load-carrying capacity and large overall dimensions. As the relative torsion angle between the two shafts increases, the tire shape becomes distorted, and the axial dimension slightly decreases, generating significant additional axial forces on the two shafts. This increases the bearing load and reduces service life. When the tire coupling operates at high speed, the outer edge of the tire expands outward due to centrifugal force, further increasing the additional axial force. Therefore, measures should be taken during installation to ensure that the stress direction in the tire is opposite to the stress direction generated during operation, thereby offsetting part of the additional axial force and improving the working conditions of the coupling and the two bearings.

Sauter Feinmechanik coupling features

Diaphragm couplings can compensate for axial, radial, and angular offsets 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 metal diaphragms to connect the driving and driven machines and transmit torque. They offer 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 the 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, no noise, and no wear. 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 convenient installation and disassembly. Installation and disassembly can be performed without moving the machine (for types with an intermediate shaft), and no lubrication is required. 6) Can accurately transmit rotational speed without slip, suitable for transmission in precision machinery.

Sauter Feinmechanik 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 methods of couplings are quite 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 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 deviations remain within the allowable range for normal operation 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 the torque and speed are the same but the shaft diameters differ, select the coupling model based on the larger shaft diameter. In newly designed transmission systems, select one of the seven shaft hole types specified in GBT3852; the J1 type shaft hole is recommended to improve universality and interchangeability. Shaft hole lengths shall comply with the i bearing coupling product standards.

Sauter Feinmechanik coupling precautions for use

1) Products with diaphragms have sharp edges that may cause injury; it is recommended to wear thick gloves during installation. 2) Please install protective covers or other devices around the coupling to ensure safety. 3) If the shaft misalignment exceeds the permissible value during installation, the coupling may deform, leading to damage or shortened service life. 4) The permissible shaft misalignment for the coupling includes radial, angular, and axial deviations. During installation, please adjust to ensure the shaft misalignment is within the permissible values specified in the corresponding product catalog. 5) When multiple types of misalignment occur simultaneously, the corresponding permissible values should be halved. 6) To extend the service life of the coupling, it is recommended to set the shaft misalignment to within 1/3 of the permissible value. 7) Tighten the screws after inserting the mounting shaft; otherwise, the coupling may deform. When tightening screws, use a torque wrench and do not use screws other than those provided as accessories. 8) If abnormal noise occurs during operation, stop immediately and check the installation accuracy and screw tightness separately. It is recommended to apply adhesive to the outer surface of the screws after installation and debugging are complete to enhance protection.
