Tube en céramique d'alumine en forme d'engrenage

Tube en céramique d'alumine en forme d'engrenage is a special ceramic component prepared through precision molding and high-temperature sintering processes, with a unique gear shaped geometric structure. This product is made of high-purity alumina (Al ₂ O ∝, with a purity usually ≥ 95%) material, combining the excellent physical and chemical properties of alumina ceramics with the mechanical and functional advantages brought by the special tooth shaped structure. Its typical characteristics include high hardness (HRA ≥ 85), excellent wear resistance (wear less than 1/10 of steel materials), outstanding high temperature resistance (long-term use temperature can reach 1600 ℃), and excellent corrosion resistance (can resist most acid-base corrosion).

Avantages principaux du produit

1. Excellente résistance à l'usure : Compared to metal gear parts, the service life is extended by 5-8 times, significantly reducing maintenance frequency and spare parts costs
2. Adaptation extrême à l'environnement : It can work stably under harsh conditions such as high temperature, corrosion, and vacuum, with no significant performance degradation
3. Excellent dimensional stability: low thermal expansion coefficient (7-8 × 10 ⁻⁶/℃), ensuring transmission accuracy in high temperature environments
4. Conception légère : With a density of only 40% of steel, it reduces the inertia of rotating components and improves equipment response speed
5. Electrical insulation characteristics: Volume resistivity>10 ¹⁴Ω· cm, suitable for transmission scenarios that require electrical isolation
6. Flexibilité de la personnalisation : Gear parameters (module, pressure angle, number of teeth) and ceramic formula can be adjusted according to specific working conditions

Principales questions à traiter
-Frequent shutdowns caused by wear: Traditional metal gears have a short lifespan in abrasive wear environments, while ceramic gears significantly extend maintenance cycles
-High temperature deformation affects accuracy: In high-temperature processes such as heat treatment and sintering, metal parts are prone to deformation, while ceramic parts maintain dimensional stability
-Failure in corrosive media: Metals corrode quickly in chemical environments, and the acid and alkali resistance of alumina ceramics ensures long-term reliability
-Lubrication limitation issue: In oil-free or dry operating environments, the self-lubricating properties of ceramics are superior to those of metals
-Pollution risk control: Avoid metal debris pollution in the medical and food industries, reduce ceramic wear particles, and have good biocompatibility.
