骨架(增强层)

The carcass (reinforcement) is the structural core of a conveyor belt that provides tensile strength and dimensional stability to withstand operational loads.

技术定义与适配语境
典型 骨架(增强层) 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The carcass, also known as the reinforcement layer, is the internal framework of a conveyor belt, typically composed of multiple plies of fabric or steel cords embedded in rubber. It serves as the primary load-bearing element, providing the necessary tensile strength to handle the belt's tension, impact resistance to absorb material loading forces, and dimensional stability to maintain proper tracking and alignment under varying operational conditions. In boom conveyor belts, this component is critical for supporting heavy loads over extended distances while resisting elongation and deformation.

定义
The carcass, also known as the reinforcement layer, is the internal framework of a conveyor belt, typically composed of multiple plies of fabric or steel cords embedded in rubber. It serves as the primary load-bearing element, providing the necessary tensile strength to handle the belt's tension, impact resistance to absorb material loading forces, and dimensional stability to maintain proper tracking and alignment under varying operational conditions. In boom conveyor belts, this component is critical for supporting heavy loads over extended distances while resisting elongation and deformation.
工作原理
The carcass functions by distributing tensile forces evenly across its plies or cords when the belt is under tension from the drive system and loaded with materials. It resists stretching and maintains the belt's shape, allowing it to carry loads without excessive sagging or tearing. The reinforcement materials (fabric or steel) provide high strength-to-weight ratios, while the rubber matrix protects them from wear, moisture, and environmental factors, ensuring durability and consistent performance.
材料
Typically made from multiple plies of polyester (EP) or nylon (NN) fabricor steel cordsembedded in synthetic rubber (e.g.SBRNR). For heavy-duty applications like boom conveyorssteel cord reinforcement is common due to its high tensile strength and low elongation.

2-6 plies (fabric) or 1 layer (steel cord)
Thickness
3-15 mm
Width Range
500-3000 mm
Tensile Strength
1000-5000 N/mm
Elongation at Break
1-3% for steel cord, 10-25% for fabric

常见问题

What is the difference between fabric and steel cord carcass in conveyor belts?

Fabric carcass uses multiple plies of polyester or nylon for flexibility and moderate strength, suitable for general use. Steel cord carcass employs steel cables for high tensile strength and low elongation, ideal for long-distance or heavy-load applications like boom conveyors.

How does the carcass affect conveyor belt performance?

The carcass determines the belt's tensile strength, impact resistance, and dimensional stability. A properly designed carcass ensures efficient load carrying, minimal stretching, and reduced maintenance, critical for boom conveyor operations in mining or construction.

What standards apply to conveyor belt carcass construction?

Key standards include ISO 15236 for steel cord belts, DIN 22102 for fabric ply belts, and ISO 283 for tensile testing, ensuring safety, durability, and performance in industrial settings.
