Technical Field

[0001] This invention relates to the field of mechanical structure design, intelligent manufacturing and automated conveying equipment technology, specifically to a detachable, modular polyurethane wheel. Background Technology

[0002] The detachable, modular polyurethane roller is a key component in intelligent manufacturing and automated conveying equipment. Currently, roller-driven drive wheels are widely used in low-to-medium speed precision conveying applications, particularly in automotive painting lines, coating assembly lines, and logistics conveying systems. However, most existing polyurethane wheels employ an integral structural design, where the metal core and polyurethane wheel body are integrally molded through coating or bonding. This structure suffers from high manufacturing costs, inconvenient maintenance and replacement, poor structural rigidity and reliability, and limited versatility. Utility Model Content

[0003] The purpose of this invention is to solve at least one of the technical problems existing in the prior art by providing a separate, detachable polyurethane wheel for the roller assembly.

[0005] According to the detachable polyurethane wheel component provided by this utility model, the first and second toothed spline structures are respectively external cam tooth structures, which mesh with each other and are fitted into the inner wall of the first polyester wheel. Through these components, torque transmission is achieved and misalignment during rotation is prevented.

[0006] According to the detachable polyurethane wheel component provided by this utility model, the first through hole and the second through hole are connected by a threaded fit and secured with several bolts, enabling the first and second detachable mechanical components to be detachably positioned and connected. These components facilitate the use of each part.

[0007] According to the modular, detachable polyurethane wheel assembly provided by this utility model, both the first and second countersunk holes are tapered countersunk structures used for embedding countersunk screws. These components ensure a smooth outer surface after connection, preventing interference with the running track or other accessories.

[0008] According to the detachable polyurethane wheel component provided by this utility model, the inner ring groove cooperates with the first and second toothed spline structures to form a multi-point locking structure. These components enhance the stability and torsional resistance of the polyurethane wheel during rotation.

[0009] According to the detachable polyurethane wheel component provided by this utility model, the steel retaining ring is made of Q235 steel plate by laser cutting and stamping, and has a conical countersunk hole structure on its edge. Through the above components, the steel retaining ring is made of Q235 steel plate by laser cutting and stamping, and has a conical countersunk hole structure on its edge.
