Multi-row pointed-tooth chain

What is a pointed-tooth chain?

A pointed-tooth chain is a specialized type of chain typically featuring chain plates with pointed-tooth structures, widely used in industrial applications.

Structural Features

Spiked chains are usually composed of chain links. Each link features outer plates at both ends, with inner plates attached to the inner walls of the outer plates. Pins are inserted between the outer and inner plates, with rollers mounted over the pins. Sleeves are fitted between the rollers and pins. The key feature is that the conveying edges of both outer and inner plates are formed into protruding and recessed spiked teeth.

Working Principle

Pointed tooth chains utilize ANSI/ISO standard roller chains that mesh with sprockets for transmission. The pointed teeth on the chain plates grip the material, enabling synchronized movement between the chain and the conveyed goods.

Application Fields

Pointed tooth chains are extensively used in the wood processing industry for gripping and conveying timber. They are also commonly employed in textile machinery and similar fields to transport strip-shaped items.

Advantages

The interlocking tooth design on the chain plates increases friction with conveyed materials, preventing slippage on the conveyor line. This ensures stable transport and enhances safety.

What is a multi-row pointed-tooth chain?

A multi-row pointed-tooth chain is a mechanical power transmission chain composed of multiple parallel rows of chain links connected by pins, with each row featuring pointed teeth.

Structural characteristics

Features a multi-row link structure, commonly available in double-row, triple-row, quadruple-row configurations, etc. The pointed-tooth design provides enhanced grip during sprocket engagement, effectively improving power transmission efficiency.

Materials and Specifications

Typically manufactured from high-strength carbon steel, offering durability and wear resistance. Available in various specifications such as 08B-4, 10A-4, and 12A-4 to meet diverse equipment requirements.

Performance Advantages

 The multi-row structure enables higher load capacity and superior transmission stability, reducing chain skipping and derailment. The pointed teeth enhance meshing efficiency with sprockets, minimizing mechanical wear risks while maintaining reliable transmission performance under high-speed or heavy-load conditions.

Application Areas

 Widely used in household, industrial, and agricultural machinery, including conveyors, plotters, printing presses, automobiles, motorcycles, and bicycles. Also suitable for woodworking machinery such as multi-blade log saws, ensuring stable cutting and enhancing processing efficiency and precision. Additionally applicable in industrial sectors requiring high-strength transmission, such as construction equipment and production line systems.
