Polyurethane Flywheel

Features and advantages of QIBR polyurethane flywheel

IBR polyurethane flywheel addresses several critical issues in diverse fields, mainly in the following areas:

1. Protruding inner race design

The protruding part of the inner race of the QIBR polyurethane flywheel helps enhance the bearing’s load capacity and stability, particularly in applications with high load requirements. It may improve mechanical performance by increasing the bearing’s contact area.

2. Shock absorption and noise reduction

The QIBR polyurethane flywheel has good elasticity and buffering properties, effectively absorbing vibrations and reducing noise.

3. Oil and chemical corrosion resistance

The QIBR polyurethane flywheel has good resistance to oils, solvents, and various chemicals.

4. Impact resistance

The high elasticity of the QIBR polyurethane flywheel provides good impact resistance, making it suitable for environments with impact loads.

Performance improvements and solutions for QIBR polyurethane flywheel

1. Improving wear resistance

By adding reinforcing materials (e.g., carbon black, ceramics, metal powders), the hardness and wear resistance of polyurethane can be increased, ensuring stable performance under higher loads and prolonged usage conditions.

2. Enhancing oil and chemical resistance

Depending on the application environment, selecting polyurethane formulations with stronger resistance to chemicals and oils can extend the service life of bearings in challenging conditions.

3. Optimizing the thickness of the polyurethane layer

The thickness of the polyurethane layer directly affects the performance of the bearings. Appropriate thickness can improve impact resistance and wear resistance. However, excessive thickness might reduce the rigidity of the bearings, impacting performance. A well-designed polyurethane layer ensures a balance between shock absorption, wear resistance, load-bearing capacity, and operational stability.

4. Inner and outer race structure optimization

By optimizing the geometry and dimensions of the inner and outer races, the polyurethane layer can be subjected to uniform force distribution, avoiding localized excessive wear.
