1. What is an encoder coupling? Types of ringfeder encoder couplings

An encoder coupling is a specialized type of coupling used to connect an encoder (a device that measures position or rotation angle) to a motor shaft or other mechanical components in a drive system. This coupling is responsible for accurately transmitting torque and rotation angle from the motor shaft to the encoder, ensuring that the measurement parameters are not distorted.
Typical types of ringfeder encoder couplings GWB series codes such as GWB DKN, GWB AKN, GWB PKA, GWB CKN, GWB AK, GWB EKN, GWB AKD, GWB AKD-H,..

2. Characteristics and applications of encoder coupling

2.1 Characteristics

Origin: Ringfeder/ Germany
Compact design
Couplings with high torsional stiffness to transmit torque at the same angle almost without maintenance and wear and have extremely low moment of inertia
Constituted of two aluminum shafts and stainless steel tubes. Its metal tube compensates for axial, radial and angular misalignments with only low restoring force.
Low moment of inertia
Suitable for highly dynamic applications.

2.2 Applications

Encoder couplings in general and ringfeder encoder couplings in particular are widely used.

ringfeder encoder coupling combined with motor x gear box (motor×gear box): Application to measure the speed of water flow in operation
Motor×encoder conveyor: Application to count the quantity on the packaging line.
Motor×ball screw conveyor, motor×measuring tester,..
For example, machine tool chain: feed shaft, main shaft drive, packaging technology: positioning application, conveyor technology, textile machinery: positioning application, chemical and pharmaceutical, food and beverage.

3. Instructions for installing encoder coupling correctly

Step 1: Extremely important! Turn off all electrical equipment on the maintenance system to protect the machine from accidentally turning on.
Step 2: Remove the coupling bolt clamp. Clean the shaft hole to ensure removal of impurities and grease. Proceed to install the coupling.
Step 3: Use a fixing tool to adjust and align the coaxiality of the two ends of the coupling accurately, avoiding eccentricity.
To check for eccentricity: While installing the coupling without tightening the bolts, slide the coupling in the axial direction to check for smoothness. Then rotate the coupling to ensure it operates smoothly.
Step 4: Use the TONE torque wrench - a hand tool brand from Japan. To tighten according to the torque specified for each size according to the product catalog, ensure the bolts and nuts are tightened.
