THE FEATURES AND APPLICATION SCENARIOS OF THE FLEXIBLE PIN COUPLING

The Flexible Pin coupling (Pin and Bush Coupling) is a widely used flexible coupling. It mainly connects the two halves of the coupling through pins and elastic elements (such as rubber sleeves or nylon rods) to transmit torque, buffer and reduce shock, and compensate for installation deviations of the two shafts.

Today, let's learn about the features and application scenarios of the flexible pin coupling.

The elastic pin coupling(Pin and Bush Coupling) is suitable for various coaxial transmission systems. It transmits torque using the cross-sectional shear strength of the nylon rods, with a nominal torque of 160-160,000 N.M, and a working temperature range of -20- 80℃.

The flexible pin coupling has the following features:

1. Simple structure: Few constituent parts, convenient for manufacturing and maintenance.

2. Easy installation: When replacing elastic elements (such as nylon pins, etc.), it is usually not necessary to move the driving and driven equipment.

3. Compensation capacity: It can effectively compensate for axial, radial and angular offsets of the axis.

4. Shock absorption and buffering: The elastic element has excellent vibration absorption and buffering performance, reducing impact.

5. No lubrication required: Nylon or rubber elastic elements usually have self-lubricating properties and do not require additional maintenance or lubrication.

6. Load-carrying capacity: It can transmit a large torque. Under the same torque, its rotational diameter is usually smaller than that of a gear coupling, and its volume is more compact.

The popular series of the elastic pin couplings(Pin and Bush Coupling) are Flender RUPEX、KWD BOKU、KWD BOKU-N、KTR REVOLEX etc.

The elastic pin coupling is widely used in the medium-speed transmission systems of various general mechanical equipment, such as:

1. Lifting and transportation machinery

2. Mining machinery

3. Metallurgical machinery

4. Textile machinery

5. Chemical machinery

Installation and Maintenance

During installation of the Flexible Pin coupling (Pin and Bush Coupling) , ensure the two shafts are basically aligned, with deviations controlled within allowable limits. Tighten the pins evenly, avoiding overtightening or loosening. Replace it immediately if cracks, aging, or severe deformation are found. Pay attention to lubrication to prevent premature failure due to dry friction between the pin hole and the pin.
