Large torque conveyance gear shaft coupling for processing machinery NS series made in Japan
Structure It consists of a hub outer cogwheel treated with unique crowning
and a sleeve inner cogwheel that engage with each other.
It also features coupling mechanisms in two places that adjust the angle depending
on the sliding of the tooth surface.
This design allows shaft adjustment and torque conveyance to be performed.

Merit 1: Japan made! Consistently high-quality production system
(exclusive manufacturer of dynamic shaft couplings since 1970)
•Consistent high-quality production under management of a Japanese factory,
from design, manufacturing, assembly, inspection, to shipping•Using our accumulation of skills unique to exclusive manufacturers,
we offer customers the optimal coupling that combines standard and special products•This also shortens the lead time from design to shipping
Merit 2: Large torque conveyance and high reliability
(particularly good for steel manufacturing machines)
•The cogwheel torque conveyance mechanism can convey a significantly larger torque
compared to other mechanisms!•It is used in a wide variety of industrial heavy machinery and machinery,
and over 15 million units have been delivered.•In particular, in the iron and steel manufacturing industry, we have a track record of
using various types in the periphery of rolling mills, including shear pin types, spindle types,
and long axis types.
Merit 3: Large misalignment tolerance (allows up to 8 degrees of angle variation!)•Due to the cogwheel mechanism, it has large tolerance values for parallel variation,
angle variation and axis direction variation, which supports smooth operation.•Using unique in-volume curved cogwheels, recently developed through collaboration
between industry and academia, the maximum angle variation is 8 degrees
Merit 4: Long lifetime and stable costs•Unlike other types of coupling, the conveyance element does not wear due to age or get
worn down due to fatigue fractures, and can last a long time with appropriate maintenance.
Furthermore, it has an excellent cost-performance ratio and maintains stable costs
for long periods of time.

Special types
1.Brake drum typeUsed as a brake mechanism
2. Slide typeUsed when the axis of the following machine moves towards the thrust direction.
3.Central axis typeUsed when the mounting dimensions of the driving and following axes are long.
4. Shear pin typeIf a large twisting moment is applied to the conveying axis,
the internally installed shear pin breaks and protects the machinery.
