German ASMI coupling ASMI model ASMI price

ASMI 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 central slider. As a torque-transmitting element, the central slider is usually made of engineering plastic; in special cases, other materials such as metal can be selected.

ASMI coupling drive system

Diaphragm coupling shafting drive system: Shafting transmission usually connects the driving and driven shafts with one or several diaphragm couplings to form a shafting drive system for transmitting rotation or motion. Diaphragm couplings are mainly used for connecting the shafts of motors, gearboxes, and working machines. The bore shape, connection type, and dimensions mainly depend 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 are specific 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 different diaphragm coupling standards. Due to the misleading influence of GB/T3852, China's diaphragm coupling product standards correspond to multiple bore lengths for each specification as the bore changes. When converting foreign diaphragm coupling standards into Chinese standards, multiple bore lengths were also added, as if this were necessary for complete conversion.

ASMI coupling application range

Widely used in shafting transmissions 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 warships, 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 shafting transmissions has become relatively common.

ASMI 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 reduced service life. 4) The permissible shaft misalignment of the coupling includes radial, angular, and axial deviations. During installation, please adjust to ensure that 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 keep the shaft misalignment within 1/3 of the permissible value. 7) Tighten the screws after inserting the installation shaft; otherwise, the coupling may deform. When tightening screws, please 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 the 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.
