Selecting Couplicon-miniTM Couplings
    Couplicon-miniTM couplings are mechanical components for transmitting the torque and rotational angles. Select the type which best fits your requirement.
Refer to the specification table of the type you have selected for deciding which product you exactly need (select the bore as well. Confirm that the Rated Torque, Max. Rotational Frequency, and Dimensions of the coupling type you have selected are adequate for the equipment you intend to use it with.
The Max. Torque of the Couplicon-miniTM is two-fold of the rated torque which exceeds 50% of the peak torque, in case a peak torque becomes generated at startup and stop of the equipment you are using.

Non-standard Couplicon-miniTM couplings can be custom-made to fit specific your specification. NBK makes every effort to manufacture these at low-cost and within the shortest time possible.


Attachment to Shaft
 Three types of couplings are available for attachment on a shaft, namely the setscrew type, clamp type, and keyway type.
Setscrew type
 This low-cost type features the most conventional attachment.

Clamp typeM
This type becomes clamped on the shaft by the tightening of the socketscrews. Attachment and removal is easy, and no shaft damage results.

Keyway type
This type, which like the setscrew type features the most conventional attachment, is used for transmitting relatively high torques. Setscrews are applied for preventing shift towards the axial direction.

Adjusting Alignment
 Flexible couplings transmit the torque and rotational angles while absorbing misalignment. When the misalignment exceeds allowable values, vibration may result or the life of the coupling may become shortened. Make sure to adjust the alignment accordingly.

There are three types of shaft misalignment, namely in terms of eccentricity (errors in parallel alignment), angularity (errors in angular alignment), and end-play (shifts in axial direction). Adjust the alignment to be below allowable valves listed in the specification table of each product provided in this catalog. We recommend you to adjust the shaft alignment to be below one-third of maximum values, as doing so will elongate the life of the coupling

Important

  1. Take note that operation under misalignment exceeding maximum values and excessive torque may result in shorter life of the coupling due to plastic deformation.

  2. Stop the rotation machine immediately if you hear an abnormal metallic noise coming from it. Proceed to check the alignment of the shaft, for any disturbances in shaft rotation, loose screws, etc. Correct the cause before restarting.

  3. If you are using rotation machine that comes under significant load fluctuation apply an adhesive on the screws to prevent them from becoming loose. Using a coupling one rank above is also recommendable.
