TORQUE LIMITED CROSS MORSE

Safety coupling- Torque limited Cross Morse

The torque limiter is a protective device that limits torque transmitted in a drive system by slipping when a preset value is exceeded as a result of shock load, overload or machine jam. It automatically re-engages when the overload is removed, no setting being required. Torque is transmitted by spring loaded friction faces, the value being preset by adjustment of the spring force by simple setting of the adjustment of the nuts and bolts. 

Torque limited Cross Morse's suitable to use with

sprockets
Gears
pulleys or
a flange plate as the centre member clamped between the friction facings.
Our low cost protection devices range includes:

the original Torque limited Cross Morse for an economical and durable solution and 
the Sheargard range for more accurate torque control and shaft synchronisation.

Characteristics Torque Limiters Couplings

The Torque Limited coupling combines overload protection with ability to connect in-line shafts. The unit consists of a standard Torque Limiter and platewheel connected to a special coupling sprocket by duplex roller chain.

The original series torque limiters and spares based on Imperial dimensions and a new range of metric torque limiters providing both smaller and larger units. Both series are available with a roller chain coupling.

Available in eleven standard sizes, they are easy assembly units providing protection and reliability.
The Original Torque Limiter
The Torque Limiter utilises spring loaded friction surfaces for its operation; slip torque is preset by adjustment of the spring force. The Torque Limiter can be used with a sprocket, gear, sheave or flange as the centre member clamped between two friction facings. Offered complete with a range of specially machined platewheels and shaft to shaft couplings, with torque range 3 - 8540 Nm.

Metric Series Torque Limiters Cross Morse
To extend the range of torque capability a new series of Torque Limiters is offered providing both smaller and larger sized units with a range of 1.5 to 10,000 Nm. These units are all to metric dimensions, and as with the original series are available with a roller chain coupling for shaft to shaft connection.

Torque Limiter combined with Roller Chain Flexible Coupling
The Torque Limited Coupling combines overload protection with ability to connect in-line shafts. The unit consists of a standard Torque Limiter and platewheel connected to a special coupling sprocket by duplex Roller Chain. Available in eleven standard sizes, they are easy assembly units providing protection and reliability.

Torque Limiters Platewheels
Cross+Morse recommend and offer as stock items specially machined platewheels for use with Torque Limiters. Both faces of Torque Limiter Platewheels are machined to 1.6μm surface finish. Uniform surfaces and parallel faces ensure that Torque Limiters will reliably maintain correct torque release and re-engagement. For the most economical drive design, select a platewheel from the increased range of standard stock platewheels.
