Coupling is a core component that transmits power and motion
from the driving shaft to the driven part while absorbing misalignment
and any possible factors that could reduce efficiency of machines
(e.g. vibration, noise, electric current, etc.)

Why Couplings?

1. Power Transmission

The core role of a coupling is to transmit motion (Torque) from “Driving shaft” to “Driven shaft”

2. Absorption of Misalignment

Due to such mechanical tolerance, precision grade and proficiency, misalignment occurs between driving and driven parts most of the cases. This misalignment is classified as angular, parallel and end-play way and it brings excessive load onto mechanical parts which is quite sensitive to vibration and noise. Sung-il couplings (except Rigid type- SRG series) can absorb this type of misalignment. Please refer to “Dimensions / Performance” pages for more details by each coupling types.

3. Absorption of Impact/Vibration/Noise

Sometimes, there is either vibration or impact on the application e.g. motor, reducer or ball screw. If they are passed onto the application directly, the entire application including expensive devices will need repairing.
Sung-il Couplings (except Rigid type –SRG series) absorb these kinds of external factors in an effective way. Particularly the models with plastic material spacer between hubs (SHR, SJC, SOH series etc.) perform better in terms of this function.

4. Insulation of Heat and Electric current

If a motor is used for a long time, heat and electric current may get occurred. If the heat is also transmitted to the driven part, there is possibility of expansion of connected parts which will reduce the precision of application. Sung-il Couplings can protect the application and keep its performance stable in an effective way through insulating heat and electric current.

5. Performance Improvement

With SHR series (High performance Rubber type), the gain value on the motor could be set higher thanks to superior damping decrease. This feature allows the stabilization time to be reduced and make whole efficiency higher.
