Torque limiters

H-TLC operates on the same basic principle as Torq-Tender, except the torque setting Is adjustable and it uses polymer materials in its major components to resist corrosion.

If operating conditions require periodic changes in torque settings, the H-TLC gives you that ability. Simply adjust the unit's external compression bolts until the desired new setting is reached.

Unlike friction-type designs, you can submerge an H-TLC in oil and still depend on precise disengagement at your design limits.

Safety coupling HAFNER
max. 1000 Nm

HAFNER-safety couplings discon-nect the drive from the machine quickly, safely and precisely..

This means that the kinetic energy of the motor and of all driving elements is disconnected up to the safety coupling, so reducing the extent of any damage to a minimum. After repair work the coupling is immediately ready for full operation. It engages automatically in its original position. (one reference point per 360°) Expensive repairs, high costs after a break-down as well as delays in delivery are avoided.

- inexpensive, short delivery periods
- customizable
- minimal residual friction through degressive spring characteristic
- exact limitation of torque
- progressive adjustment of cut-out torque
- compact construction, low moment of inertia, high speeds possible

Safety coupling VOITH TURBO

Safeset® is a torque limiting safety coupling for release torques from 500 to 10,000,000 Nm. With shapes and sizes and shaft diameters from 30 to 1,000 mm it is excellently suited for any type of system.

The Safeset safety coupling is comprised of a twin-walled pressure sleeve that is inflated at an oil pressure of up to approx. 1,000 bar and is released absolutely tightly by several shear-off tubes.
A shear ring cuts off the shear tube and thereby protects the system from overload; bearings prevent the contact of friction surfaces. A special oil used in the pressure surface and bearing areas guarantees a constant coefficient of friction and thereby high release accuracy.

As opposed to break-off element couplings, the release torque is not influenced by material fatigue.

Torque limiter Cross Morse

The Morse Torque Limiter is a protective device that LIMITS TORQUE transmitted in a drive system by slipping when the torque demand exceed a preset value as a result of shock loads, overloads, or machine jams. It automatically re-engages when the overload torque has passed; no re-setting is required. It prevents machine damage and eliminates costly breakdown time.

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.
Simple Design . Easy Adjustment. Wide Torque Adjustment. Compact . Minimum Maintenance. Economical. Dependable. Durable.

Morse introduced the first spring loaded, friction type protective device which was developed to 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.

Torque limiter Ortlinghaus

Ortlinghaus multiplate safety clutches are permanently engaged, this condition being maintained by spring pressure. They are able to transmit torque up to a particular, preset level, after which in the case of an overload in the transmission, they are designed, to slip for a limited period of time. They can thus be used to safeguard all types of transmission lines in machines and equipment from overloading and destruction. They have the task of smoothing out high torque peaks, at start ups, and during the operating of a line. This is done by the clutch plates slipping past each other for a short period of time when the desired maximum torque is reached.

The torque at which a clutch starts to slip can be varied, within limits. In this way these clutches safeguard gear wheels, shafts and other drive elements from damage and thus guarantee operational reliability for an extended period of time; in this way they also help to prevent the need for repairs. It must be kept in mind that when the clutch is slipping, frictional heat is produced and released within the set of plates and that the permissible amount of heat is limited. This thermal loading must be kept within the required limit with the aid of a slip monitoring device, which would switch off the drive. This is necessary with fast running drives where the critical amount of heat is reached very rapidly when slipping commences.
