EDITOR’S CHOICE CROSS & MORSE TORQUE LIMITERS Cross & Morse Torque Limiters are low cost protection devices that limit torque in a drive system in order to:- • • Prevent machine and drive damage. Eliminate costly machine downtime. The Morse Torque Limiter 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 re-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 nuts and bolts. The Torque Limiter is suitable to use with sprockets, gears, pulleys or a flange plate as the centre member is clamped between the friction facings. The Torque Limiter can accommodate shaft sizes of 5mm to 120mm (3/16 to 4.5”) and torque ranges of 3Nm to 10,000Nm (2.2 to 7375 lbs ft) The Torque Limiter is not a new product with Cross & Morse. In 1949 Morse introduced the first spring loaded, friction type protective device which was developed to suit today’s line of products consisting of 7 sizes, the models 200M to 700M being the most popular units. To further extend the capabilities of our products a new metric series of clutches, consisting of 6 sizes from M30 to M280 has been added, to cater for higher torque applications, and areas where space is limited. As the originator of the Torque Limiter, Morse gained vast experience in the design and application of these units as trouble free and long lasting protective devices. Many thousands of units have been fitted to conveyors, mechanical handling equipment and agricultural machines proving the reliability of the product. www.crossmorse.com Cross + Morse Power Transmission Manufacturing Specialists in the UK Since 1984 ◊ Manufacturing up to 1450mm diameter ◊ Turning - CNC lathes, Vertical Machining Centre ◊ Gear Cutting - Hobbing, Planing, Shaping Gears ◊ Bevel Gears, Helical, External & Internal cut Spur Gears ◊ Worms & Worm Wheels ◊ Rack Shaping, Broaching, Keywaying ◊ Vertical Boring, Centreless & Rotary Grinding ◊ Bore Honing ◊ Induction Hardening ◊ Drilling & Tapping ◊ Large stocks of Transmission Drive components ◊ CAD - CAM Design & Development Yes we can make it.
