Component Specifications

Definition
A tooth ring is a critical annular gear component manufactured through polypropylene injection molding processes, designed to transmit torque and rotational motion within gear assemblies. It features precisely engineered teeth profiles that mesh with mating gears to achieve specific speed ratios and power transmission requirements in mechanical systems.
Working Principle
Operates on gear meshing principles where the tooth ring's precisely molded teeth engage with corresponding teeth on mating gears to transfer rotational motion and torque. The polypropylene material provides self-lubricating properties, reducing friction and wear during operation while maintaining dimensional stability under load.
Materials
Polypropylene (PP) homopolymer or copolymer, typically with 20-40% glass fiber reinforcement for enhanced mechanical properties. Material specifications include: PP-GF30 (30% glass fiber), density: 1.12-1.23 g/cm³, melt flow index: 10-30 g/10min (230°C/2.16kg), tensile strength: 60-100 MPa, flexural modulus: 3000-5000 MPa.

Frequently Asked Questions

What are the advantages of polypropylene tooth rings over metal gears?

Polypropylene tooth rings offer self-lubrication, corrosion resistance, noise reduction, lighter weight, and lower manufacturing costs compared to metal gears, making them ideal for moderate-load applications.

What maintenance is required for polypropylene tooth rings?

Minimal maintenance is required due to polypropylene's self-lubricating properties. Periodic inspection for wear, cleaning to remove debris, and ensuring proper alignment with mating gears are recommended.

Can polypropylene tooth rings be used in high-temperature applications?

Standard polypropylene tooth rings are suitable for temperatures up to 100°C. For higher temperatures (up to 150°C), heat-stabilized or glass-reinforced grades should be used.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
