Composite Housing of a Belt Conveyor Roller Made of PA6 GF30: Design Features, Manufacturability, and Operational Reliability

Abstract

The article presents the design of a composite housing for a belt conveyor roller made of polyamide 6 reinforced with 30 % glass fibre (PA6 GF30). The key manufacturing and design features are described: a system of stiffening ribs, roller-flanging of the tube edge instead of welding, dust-protection elements and guides for bearing centring. Laboratory and industrial tests confirmed the geometric stability, impact resistance, abrasion resistance and fault tolerance of the design. The development is intended for use in abrasive and humid environments, ensuring reliable and safe operation of conveying equipment.
