German FENNER DRIVES couplings, FENNER DRIVES models, FENNER DRIVES prices

FENNER DRIVES couplings are components that connect the prime mover to the driven machine. Their main function is overload protection. The torque limiter restricts the torque transmitted by the drive system by slipping when the required torque exceeds the set value due to overload or mechanical failure. It automatically re-engages once the overload condition disappears. This prevents mechanical damage and avoids costly downtime losses.

Features and applications of FENNER DRIVES couplings

1) Cross universal couplings enable two shafts that are not on the same axis, with large axis deflection angles and significant axial movement, 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 use an integrated yoke head, making operation more reliable. 4) Cross universal couplings have a compact structure, high transmission efficiency, low noise, long service life, and are easy to maintain 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.

FENNER DRIVES 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 yokes are in the same plane; the allowable deviation must not exceed 1°. The spline part should slide freely, and the joints should rotate flexibly. Clean the surfaces. Except for the flange end faces and end face keys, which should be coated with anti-rust grease, apply one coat of anti-rust primer to the rest, then paint (do not brush paint).

FENNER DRIVES 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 based on the magnitude of 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, triple-yoke cross universal couplings, triple-ball-pin cross universal couplings, and hinge-rod cross universal couplings, among others. The most commonly used type is the cross-axis cross universal coupling, followed by the ball-cage cross universal coupling. Maintenance method for cross universal couplings: Regular lubrication is recommended, with oiling once a week, or daily under high-temperature conditions. To increase the service life of the universal coupling, adjust the cross shaft by 180 degrees during each disassembly to alternate the use of the cross shaft journals.
