German warner coupling warner model warner price

The warner coupling connects several sets of diaphragms (thin stainless steel plates) to the two coupling halves with bolts in an alternating arrangement. Each set of diaphragms consists of multiple stacked layers. The diaphragms are classified into link-type and solid-piece types of various shapes. The diaphragm coupling compensates for the relative displacement between the two connected shafts through the elastic deformation of the diaphragms. It is a high-performance flexible coupling with strong metallic elements, requiring no lubrication. It features a compact structure, high strength, long service life, no rotational backlash, and is unaffected by temperature or oil contamination. It offers acid resistance, alkali resistance, and corrosion resistance, making it suitable for shaft drive systems operating in high-temperature, high-speed, and corrosive media environments.

warner Coupling Features and Applications

1) Cross universal couplings enable continuous constant-velocity rotation of two shafts that are not on the same axis, have large axis angles, and significant axial movement. 2) Cross universal couplings reliably transmit torque and motion. Their primary feature is substantial angular compensation capability. 3) Cross universal couplings use integrated yokes, enhancing operational reliability. 4) Cross universal couplings have a compact structure, high transmission efficiency, low noise, long service life, and are easy to maintain. Cross universal couplings are suitable for transmitting torque in the shaft systems of machinery in metallurgical, heavy, petroleum, engineering, lifting and transportation, locomotive and vehicle, light industry, precision, and control machinery, as well as other heavy machinery industries.

warner Coupling Installation

Assembly technique for cross universal couplings: During assembly, remove burrs and clean all parts. Ensure that the centerlines of the bearing holes of the two intermediate welded yokes are on the same plane, with an allowable deviation not exceeding 1°. The spline section should slide freely, and the joints should rotate flexibly. Clean the surfaces; except for applying anti-rust grease to the flange end faces and end face keys, apply one coat of anti-rust primer to the rest, followed by paint (do not brush paint).

warner Coupling Structure and Maintenance

Cross universal couplings come in various structural types. Their primary feature is substantial angular compensation capability, compact structure, and high transmission efficiency. In practical applications, they are classified into heavy, medium, light, and small types based on the torque transmitted by the universal shaft. Types include cross-axis cross universal couplings, ball cage cross universal couplings, ball fork cross universal couplings, block-type cross universal couplings, ball pin cross universal couplings, ball joint cross universal couplings, ball joint plunger cross universal couplings, three-pin cross universal couplings, three-fork rod cross universal couplings, three-ball pin cross universal couplings, and hinge rod cross universal couplings, with the cross-axis type being the most common, followed by the ball cage type. Maintenance method for cross universal couplings: Regular lubrication is recommended, with oil injection once a week, or daily under high-temperature conditions. To extend the service life of the universal coupling, adjust the cross axis by 180 degrees during each disassembly to alternate the usage of the cross axis journals.
