Bellowflex / Kunststoffbalg-Kupplung

Product catalog summary

Overview: The document provides technical specifications and guidelines for Plastic Bellows Couplings, specifically the BELLOWFLEX series, which are designed for high damping performance and minimal counterforce due to misalignment. These couplings are ideal for use with stepper motors and encoders in various applications such as automated teller machines, inspection equipment, and printing machinery.

Main Features:

Allows angular deflection up to 10°.
Extremely small counterforce due to misalignment.
High flexibility and damping with no backlash.

Specifications:

Max. nominal torque: 1.5 N·m.
Bore ranges: φ3 ～ 12 mm.
Operating temperature: -20℃ to 60℃.
Drive compatibility: Induction motor, stepper motor, encoder.

Materials:

Hub: Aluminum alloy.
Boot: Polyester resin.
Hexagon head set screw: Alloy steel with black coating.

Model Specifications:

CHP-20: Nominal torque 0.4 N·m, max torque 0.8 N·m, max rotation speed 9000 min-1.
CHP-26: Nominal torque 0.7 N·m, max torque 1.4 N·m, max rotation speed 7000 min-1.
CHP-34: Nominal torque 1.5 N·m, max torque 3.0 N·m, max rotation speed 5500 min-1.

Handling Precautions:

Ensure operating temperature is within -20℃ to 60℃.
Avoid excessive water or oil exposure.
Prevent direct sunlight exposure to prolong service life.
Maintain alignment within specified limits for optimal performance.

Selection Procedures:

Calculate applied torque using driver output and rotation speed.
Determine service factor based on load and temperature conditions.
Select coupling size ensuring nominal torque meets or exceeds corrected torque.

Design Considerations:

Check for parallel, angular, and axial misalignment.
Ensure bolts are tightened to specified torque.
