The disc coupling is made with two hubs and a thin metallic disc. The metallic disc is the torque-transmitting element. This type is designed to bend in different directions (parallel offset). The disc design is popular in servo, stepper and drive applications for taking the load off the bearings.
Two hubs & thin metallic disc
• Metallic disc transmits torque
• Two-disc style allows bends in different directions (parallel offset)
• Misalignment up to 5 degrees
• Torsionally rigid

No need for lubrication and maintenance.
There is no need to disassemble the coupling to inspect.
Additionally, the condition of the discs can be checked
while the machine is running, using a strobe light.
The machine misalignment can be assessed.
Torsionally rigid without any backlash.
No wearing parts, high resistance to harsh environmental
conditions.
Infinite life if properly aligned.

DELTEX - shaft couplings are marked by small dimensions and
weights, as well as having low mass moment of inertia at high torque
transmission. The running properties and durability expectations
of the couplings have been obtained by precise surface finishing of all sides of the coupling. The shock loads produced by irregularly working power machines will be optimally dampened and absorbed. DELTEX – shaft couplings transfer the torque formsafe, are rotation elastic and safe against break through. DELTEX - couplings adjust axial, radial and angle changes. All steel parts are corrosion protected.
Function:
DELTEX - shaft couplings consist of two facing hubs, made of steel or aluminium, between which an elastic spider is mounted.
The elastic and form constant torque is transferred by this spider.
The elastic spiders made of special polyurethane are available in
various hardnesses according to application as well with rounded
teeth sides (DELTEX-S) or with straight teeth sides for torque transfer
free of play (DELTEX-GSS).

The Stromag GE Coupling is a highly-flexible coupling for transmission of high torques. The series covers a nominal torque range from 2000 Nm up to 270000 Nm, in special sizes also up to 450000 Nm. The torque is transmitted from the input side to the output side overcoming single elements in star-shaped arrangement.
The construction of the GE Coupling is particularly compact; it is suitable for diesel engine and electric drives. The elements can be mounted and dismantled radially without necessity to shift the connected machines.
|
|
When transmitting torque from a drive shaft to a driven shaft, flexible couplings:
absorb and dampen irregularities in the torque
distribute peak loads
Allow misalignments and offsets between the shafts
Permit some disortions in the mounting beds
Avoid the unwelcome constraints that may occur if a rigid coupling were fitted in the same conditions.
Allow a highter constructions, with wider tolerances, and lower cost.

The Stromag Periflex® Shaft Coupling is a highly-flexible rubber/fabric coupling, particularly suitable for connection of two shafts in diesel engine and electric drives. It can be used in the nominal torque range from 25 Nm up to 15000 Nm.
Due to the particularly designed shaft tyre, the Periflex® Shaft Coupling can overcome extreme offsets with low restoring forces, without noting any wear. As a standard, the rubber/fabric tyre is provided with a parting line in our works so that it can be mounted and dismantled radially without necessity to shift the connected machines.
The torque is transmitted absolutely backlash-free. The Periflex® Shaft Coupling is suitable to absorb torque peaks and to damp occurring vibrations.
The Periflex® Shaft Coupling can be used in explosion-hazardous zones.

A jaw coupling is made with two metallic hubs with an elastomer (plastic) called the spider. The spider material is soft and mainly designed to absorb vibration. It is the first piece to wear and need to be replaced. The unit functions to minimize parallel or angular misalignment at high rpm. The spider center is ideal for motor connection applications needing shock absorption.
Two metallic hubs & a spider (elastomer)
• Conventional straight or curved jaw
• Ideal for servo applications
• Excellent shock absorption
• Curved jaws reduce deformation of spider
• Limits centrifugal force
• Balanced to handle high RPM, 40k+
• Functions with minimal parallel or angular misalignment
• Unit Transmits torque in event of spider failure
• Mix and match spider to accommodate multiple environments and applications
