German FSO 600 coupling, FSO 600 model, FSO 600 price

The FSO 600 coupling consists 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 available in two profiles: straight teeth and crowned teeth. Crowned teeth refer to external teeth machined into a spherical surface, with the sphere center on the gear axis. The tooth side clearance is larger than that of standard gears. Crowned tooth couplings allow greater angular misalignment (compared to straight-tooth couplings), improve tooth contact conditions, enhance torque transmission capacity, and extend service life. During operation of gear couplings, relative displacement occurs between the two shafts, causing periodic axial relative sliding between the internal and external tooth surfaces, inevitably resulting in tooth surface wear and power loss. Therefore, gear couplings must operate under good lubrication and sealing conditions.

FSO 600 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 break angles, and significant axial movement. 2) Cross universal couplings reliably transmit torque and motion. Their most notable feature is substantial angular compensation capability. 3) Cross universal couplings adopt an integrated yoke head, enhancing operational reliability. 4) Cross universal couplings feature a compact structure, high transmission efficiency, low noise, long service life, and convenient maintenance. Cross universal couplings are suitable for transmitting torque in mechanical shaft systems across metallurgical machinery, heavy machinery, petroleum machinery, engineering machinery, lifting and transport machinery, locomotives and rolling stock, light industry machinery, precision machinery, control machinery, and other heavy machinery industries.

FSO 600 Coupling Installation

Assembly technique for cross universal couplings: During assembly, remove burrs and clean all parts. Ensure that the centerlines of the bearing holes in the two intermediate welded yokes lie in the same plane; the permissible deviation must not exceed 1°. The spline section should slide freely, and joints should rotate flexibly. Clean 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 remaining surfaces, followed by paint application (do not brush paint).

FSO 600 Coupling Structure and Maintenance

Cross universal couplings are available in various structural types. Their most notable feature is substantial 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 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, triple-pin cross universal couplings, triple-fork bar cross universal couplings, triple-ball pin cross universal couplings, and hinge bar cross universal couplings, with the cross-axis cross universal coupling being the most commonly used, followed by the ball cage cross universal coupling. 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 shaft by 180 degrees during each disassembly to alternate usage of the cross shaft journals.
