German SIEMENS FLENDER coupling, SIEMENS FLENDER model, SIEMENS FLENDER price

SIEMENS FLENDER coupling slider is ring-shaped, made of steel or wear-resistant alloy. Cross-slider couplings are suitable for transmissions with lower speeds and higher torque transmission. The slider coupling consists of two shaft hubs and a center slider. The center slider, as a torque-transmitting element, is usually made of engineering plastic; in special cases, other materials such as metal can be selected.

SIEMENS FLENDER coupling drive system

Diaphragm coupling shaft drive system: Shaft drives typically connect the driving and driven shafts using one or several diaphragm couplings to form a shaft drive system for transmitting rotation or motion. Diaphragm couplings are mainly used to connect the shafts of motors, gearboxes, and working machines. The bore shape, connection type, and dimensions depend primarily on the type and size of the connected shafts. During product design, shafts are generally designed according to international standards for cylindrical and conical shaft depths; shaft depth standards apply to shaft design. For various types of metal diaphragm couplings, during structural and series design, the bore range (maximum and minimum bores) and bore length for each specification of metal diaphragm coupling are determined based on the transmitted torque, the structure of the diaphragm coupling, and hub strength. Each specification has only one bore length. Abroad, manufacturers of diaphragm couplings specify only one bore length per specification in their respective standards. Due to misleading information from GB/T3852, Chinese product standards for diaphragm couplings assign multiple bore lengths to each specification depending on the bore variation. When converting foreign diaphragm coupling standards into Chinese standards, multiple bore lengths were also included, as if this were necessary for complete conversion.

SIEMENS FLENDER coupling application range

Widely used in shaft drives of various mechanical devices, such as water pumps (especially high-power and chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), high-speed power transmission systems of ships, steam turbines, piston-type power machinery transmission systems, tracked vehicles, and high-speed, high-power mechanical transmission systems of generator sets. After dynamic balancing, application in high-speed shaft drives has become relatively common.

SIEMENS FLENDER 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 similar devices around the coupling to ensure safety. 3) If shaft misalignment exceeds the permissible value during installation, the coupling may deform, leading to damage or reduced service life. 4) Permissible shaft misalignment for the coupling includes radial, angular, and axial deviations. During installation, please adjust to ensure shaft misalignment remains 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 keep shaft misalignment within 1/3 of the permissible value. 7) Tighten the screws only after inserting the installation 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 noises occur during operation, stop immediately and check installation accuracy, screw looseness, etc. It is recommended to apply adhesive to the outer surface of the screws after installation and debugging to enhance protection.
