Roller Chains

Product catalog summary

Main Components of Roller Transmission Chains:
Roller transmission chains are composed of shaped side plates, roller bearing pins, and rollers that engage with gear wheels. Key dimensions include internal width (W), roller diameter (d), and roller diameter (D). The pitch (p) is the distance between pins. Accessories such as connecting and offset links require spring clips or cotters for attachment.

Figures and Illustrations:
Illustrations include typical chain pitch, connecting links with different locks, assembly of side plates, and differences between offset and traditional links.

Standards and Durability:
Chains adhere to European (ISO/R 606-1982, DIN 8187) and American (ANSI, DIN 8188) standards, with American standards focusing on fatigue resistance. Wear and fatigue can affect pitch and lead to breakage if workload exceeds specifications.

Supply and Customization:
Chains are supplied in 5m rolls with common pitches, but custom lengths are available. The number of pitches is typically odd, with connecting links making it even and offset links returning it to odd.

Technical Notes on Chain Length:
For chains forming a ring with an even number of pitches, specify the number of pitches and use a riveted link.

Example for Determining Chain Transmission:
The transmission ratio (τ) is calculated as the quotient of the driven wheel (Z2) over the driving wheel (Z1). Correction coefficients C1 and C2 adjust for load type and cyclical inputs.

Transmission Chain Specifications and Design Criteria:

1. Transmission Ratio Definition: τ = Z2/Z1.

2. Correction Coefficients: Coefficients C1 and C2 are used to parameterize transmission based on load type and cyclic activations.

3. Design Criteria for a Transmission Chain:

Ensure a 120° arc wrap around the driving wheel.
Maintain proper chain tension using idler sprockets if necessary.
Ensure correct lubrication to prevent wear.

4. Chain Length Determination: Theoretical chain length (Sv) is calculated using a specific formula involving center-to-center distance, teeth numbers, and pitch.

5. Lubrication and Environmental Considerations: Lubrication type depends on chain speed and dimensions, with specific types for different temperature environments.

6. Chain Types and Specifications: Specifications for simplex, duplex, and roller chains include dimensions, breaking load, and weight per meter, adhering to ISO standards.
