Couplings

Malmedie Safety-Couplings have been used for more than 30 years as torque limiters in various executions (e.g. gear couplings, elastic couplings, cardan shafts etc.). They have thoroughly proven themselves even under very difficult application conditions, such as in the metallurgical industry and rolling mills, mining and the chemical industry. Their function is characterised by high precision of disengagement and rapid reset, effectively protecting from damage due to overload and, on the flip side, significantly reducing lost production time. All Safety-Coupling parts are produced to stringent internal quality standards. With the aid of modern CNC manufacturing technology the ability to replace individual parts is guaranteed. All load-bearing coupling parts are produced from high-quality heat-treated steel. Wear is reduced by the purposeful selection of materials and by appropriate hardening treatments. On account of the diversity of the applications, Safety-Couplings are adapted almost exclusively to the customer's request. Only the safety elements are standardised series items. Characteristics:

• high load capacity.
• robust.
• high shut-off accuracy.
• fast re-engagement.
• maintenance free.
• suitable for use in potentially explosive atmospheres according to directive 94/9/EU
• optionally with automatic wear indicator
• suitable for use in potentially explosive hazardous areas according to directive  RL 94/9/EG

Advantages of the MALMEDIE -Safety-Coupling:

• low costs due to short downtimes.
• suitable for reversing operation.
• full unlocking.
• readjustable.
• low risk of damage.
• long service life.

Developed by Malmedie, the Drum-Coupling is especially suitable for installation in drum drives of cranes and conveying systems. Highly suited to the rough conditions of steelworks, reclaimers, ship unloaders and container cranes, the Malmedie Drum-Coupling satisfies, for example, the technical requirements prescribed by the German Steel and Iron Operating Sheet (Stahl-Eisen-Betriebsblatt) SEB 666212, issued in Jan. 1991, and the Norme Sidérurgie Française. A rigid connection between the gear shaft and the rope drum results, in a single or twin drum drive, in a statically indeterminated three or four-point support.

• higher load capacity
• up to 10 % higher permissible torque
• larger permissible radial load
• larger permissible finish bore
• longer service life
• interchangeable with preceding series
• optionally with automatic wear indicator

suitable for use in potentially explosive hazardous areas according to directive  RL 94/9/EG

MALMEDIE Gear-Couplings are designed with crowned teeth, and are used where torques must be transmitted through shafts that are movable on all sides.  

The new LX and GLX series offer:

• higher load capacity.
• higher permissible torque.
• large permissible finished bore.
• longer service life.
• interchangeable with preceding series.
• suitable for use in potentially explosive areas according to directive 94/9/EG

Features of the MALMEDIE Gear-Coupling:

• compensation for angular, radial and axial misalignments.
• suitable for operation in reverse.
• quiet running thanks to gear head centring.
• special designs can also be suitable for vertical installation.
• large permissible finished bore.
• easy replacement of seals with splitted cover.
• high level of operational reliability as a result of the use of high quality materials.
• long service life with low levels of maintenance.
