German PRUDHOMME coupling PRUDHOMME model PRUDHOMME price

PRUDHOMME couplings leverage their mechanical design to enable continuous rotation of two shafts that are not collinear and have an axis angle, while reliably transmitting torque and motion. The key feature of universal joints is their high angular misalignment compensation capability, compact structure, and high transmission efficiency. The axis angle varies with the universal joint design, typically ranging from 5° to 45°.

PRUDHOMME coupling drive system

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

PRUDHOMME coupling applications

Widely used in shaft drives for 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 for ships, steam turbines, reciprocating power machinery transmission systems, tracked vehicles, and high-speed, high-power mechanical transmission systems for generator sets. After dynamic balancing, they are commonly used in high-speed shaft drives.

PRUDHOMME coupling usage precautions

1) Products with diaphragms have sharp edges that may cause injury; wearing thick gloves during installation is recommended. 2) 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 couplings includes radial, angular, and axial misalignment. During installation, adjust to ensure 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 coupling service life, it is recommended to keep shaft misalignment within 1/3 of the permissible value. 7) Insert the mounting shafts before tightening the screws; otherwise, the coupling may deform. Use a torque wrench when tightening screws, and do not use screws other than those provided. 8) If abnormal noises occur during operation, stop immediately and check installation accuracy, loose screws, etc. It is recommended to apply adhesive to the outer surface of the screws after installation and commissioning to enhance protection.
