Germany Marx-Rollentechnik coupling Marx-Rollentechnik model Marx-Rollentechnik price

Marx-Rollentechnik coupling is a component that connects the prime mover to the driven machine. Its 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.

Marx-Rollentechnik coupling features and applications

1) The cross universal coupling enables two shafts that are not on the same axis, have large axis deflection angles, and significant axial displacement to rotate continuously at equal angular velocities. 2) The cross universal coupling reliably transmits torque and motion. Its greatest feature is its large angular compensation capability. 3) The cross universal coupling adopts an integrated yoke head, making operation more reliable. 4) The cross universal coupling has a compact structure, high transmission efficiency, low noise, long service life, and is 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 rolling stock, light industry machinery, as well as precision machinery and control machinery, and other heavy machinery industries.

Marx-Rollentechnik 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 paint (do not brush paint).

Marx-Rollentechnik coupling structure and maintenance

Cross universal couplings come in various structural types. The greatest feature of the cross universal coupling is its 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 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 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.
