German Walther Flender couplings, Walther Flender models, Walther Flender prices

Walther Flender couplings consist of components such as an internal gear ring with the same number of teeth and a flanged half-coupling with external teeth. External teeth are divided into two tooth profiles: straight teeth and crowned teeth. Crowned teeth refer to external teeth machined into a spherical surface, with the center of the sphere on the gear axis. The tooth side clearance is larger than that of general gears. Crowned tooth couplings allow greater angular displacement (compared to straight tooth couplings), improve tooth contact conditions, enhance torque transmission capacity, and extend service life. When gear couplings are in operation, relative displacement occurs between the two shafts, and the tooth surfaces of the internal and external gears periodically perform axial relative sliding, inevitably causing tooth surface wear and power loss. Therefore, gear couplings must operate under good lubrication and sealing conditions.

Walther Flender coupling features and applications

1) Cross universal couplings enable two shafts that are not on the same axis, with large axis break angles and large axial movements, to rotate continuously at equal angular velocities. 2) Cross universal couplings reliably transmit torque and motion. Their greatest feature is their large angular compensation capability. 3) Cross universal couplings adopt an integrated yoke head, making transportation more reliable. 4) Cross universal couplings have a compact structure, high transmission efficiency, low noise, long service life, and are convenient for maintenance and repair. Cross universal couplings are suitable for transmitting torque in the mechanical shaft systems of metallurgical machinery, heavy machinery, petroleum machinery, engineering machinery, lifting and transportation machinery, locomotives and vehicles, light industry machinery, precision machinery, control machinery, and other heavy machinery industries.

Walther Flender coupling installation

Assembly technology for cross universal couplings: During assembly, remove burrs and clean all parts. During assembly, ensure that the centerlines of the bearing holes of the two intermediate welded yoke heads are on the same plane, with an allowable deviation not exceeding 1°. The spline part 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, then spray paint (do not brush paint).

Walther Flender coupling structure and maintenance

Cross universal couplings come in various structural types. The greatest feature of cross universal couplings is their large angular compensation capability, compact structure, and high transmission efficiency. In practical applications, they are classified into heavy-duty, medium-duty, light-duty, and small-sized types based on the magnitude of 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, triple-yoke cross universal couplings, three-ball pin cross universal couplings, and hinge rod cross universal couplings, with the cross-axis cross universal coupling being the most commonly used, followed by the ball cage cross universal coupling. Maintenance methods for cross universal couplings: Regular lubrication is recommended, with oil injection once a week, or once a day under high-temperature conditions. To increase the service life of the universal coupling, adjust the cross axis by 180 degrees during each disassembly to alternate the use of the cross axis journals.
