ABOUT COUPLINGS AND LOCKING DEVICES
InterAlia offer couplings, over load couplings and shaft and hub locking devices from the German company KBK. KBK deliver the highest quality to low cost. Quick shipping and the possibility for customization are other reasons for chosing couplings and locking devices from KBK.

WHERE ARE COUPLINGS AND LOCKING DEVICES USED?
Couplings and locking devices are used to connect shafts to each other. It can be to connect the motor shaft to the shaft of the object the motor should drive or to join to shafts of the same or different diameter. Couplings can contrary to locking devices also offer more functionality than just to connect shafts to each other. They can compensate for misalignments between the shafts or/and stop vibrations to spread through the shafts. But couplings can also incorporate over load protection which disconnects the driving force at over load condistions to protect the equipment. KBK product portfolio consists of the following types of couplings and locking devices:
• Metal belows couplings
• Over load couplings
• Servo couplings
• Intermediate shafts
• Locking devices

METAL BELOW COUPLINGS
Metal below couplings are used in many places due to their high torsional stifness and flexibility and also in applications where high torques needs to be transmitted with zero play. At the same time they can compensate for any misalignment bewteen the input and output shaft.
• All types comes in four different lengths
• Couplings available for shaft diameters from 1 – 90 mm
• Also available in inch versions
• Versions with shafts as option.

KB1 • Miniature metal belows coupling • With locking screw • Torque range: 0,1 – 10 Nm.
KB2 • Miniature metal belows coupling • With locking clamps • Torque range: 0,1 – 10 Nm.
KB3 • Miniature metal belows coupling • With expanding locking clamps • Torque range: 0,4 – 10 Nm.
KB4 • Metal below coupling • With locking clamps • Torque range: 12 – 500 Nm.
KB5 • Metal below coupling • With conical hub • Torque range: 12 – 5000 Nm.
KB6 • Metal below coupling • With outer conical hub • Torque range: 12 – 5000 Nm. .
KB7 • Metal below coupling • For flange mounting • Torque range: 12 – 5000 Nm.

OVER LOAD COUPLINGS
Over load couplings offer extremily fast reaction times (milliseconds) which means that the driving force is disconnected almost instantaneously. They offer a safe method to protect both persons and equipment and reduce off time and repair costs to a minimum. Further they are insensitive to temperature changes and grease and lubricants do not change the function. The release torque is adjustable and at the set torque the coupling imediately disconnects the force. When the torque falls under the set level the coupling will start to work again automatically.
• All over load couplings can be delivered in different length.

• Couplings available for shaft diameters from 6 – 90 mm! Inch versions also available.
• Versions with shafts as option.
• Different torque ranges available for all types.
 

KBK/L • Over load coupling • For mounting on timing belt wheels, gear boxes and similar • Torque range: 0,5 – 1600 Nm.
KBK/BK • Over load coupling with metal belows • With locking clamps • Torque range: 1 – 500 Nm.
KBK/BI • Over load coupling with metal belows • Used to join shafts • With conical hub • Torque range: 3 – 1600 Nm.
KBK/EK • Over load coupling with elastic ring which reduce vibrations • Used to join shafts • With locking clamps • Torque range: 3 – 500 Nm.
SERVO COUPLINGS Servo couplings has an elastic and play free transmission which reduce vibrations that allows a servo motor system to perform at the highest accuracy and with the maximum dynamic responce.
KBE • Over load coupling with elastic ring which reduce vibrations • Available with locking screw, locking clamps or conical hub • Couplings for shaft diameters from 4 – 75 mm! Inch versions available. • Torque range: 0,5 – 500 Nm.
INTERMEDIATE SHAFTS Intermediate shafts has couplings in the ends and are used to connect one or several units to the same transmission line. Lengths up to three meter are standard and the shafts comes in different diameters to cover torques up to 500 Nm. There are two types of shafts, either with metal belows coupling (DRB) or with servo coupling (DRE).
DRB • Intermediate shafts with metal belows couplings • Shaft and hubs in aluminium • Belows in stainless steel.
DRE • Intermediate shafts with servo couplings that reduce vibrations • Shaft in aluminium • Hubs in aluminium or stainless steel.

LOCKING DEVICES
Locking devices are used to join shafts or hubs to other shafts and hubs with a connection that are play free and can transmitt high torques. Conical elements makes the connection between drive shafts, internediate shafts, belt wheels, gear boxes and chain wheels. Simple and quick mounting means low comissioning costs.
