When it comes to power transmission in industrial and automotive applications, few components are as essential as the V-belt. Whether you're replacing a worn belt or designing a new system, understanding the different types and constructions of V-belts is critical.
At AIMS Industrial, we don’t just offer V-belts—we offer insights, expertise, and a seamless shopping experience backed by technology.
What Are the Main Types of V-Belts?
V-belts come in various configurations tailored for performance, durability, and specific operating conditions. Here's a breakdown of the most common types:
1. Classical V-Belts
These are the traditional belts with a standard height-to-width ratio. Commonly used in legacy systems, classical V-belts are reliable options for equipment that requires standard replacements.
2. Narrow V-Belts
Designed for higher power transmission at higher speeds, narrow V-belts have a deeper cross-section. They are ideal for compact systems with high torque demands.
3. Wrapped V-Belts
Covered in fabric, these belts offer extra protection against environmental factors. Wrapped V-belts are typically used in general-purpose industrial applications where stability and durability are key.
4. Cogged (Notched) V-Belts
With slots cut across the underside, cogged belts offer increased flexibility and better heat dissipation. They're perfect for small pulley diameters and high-speed drives.
5. Double V-Belts (Hexagonal Belts)
These belts have V-shaped profiles on both sides, making them suitable for serpentine drives or systems where power needs to be transmitted from both sides of the belt.
6. Banded V-Belts
Multiple V-belts bonded together to form a single unit, banded belts resist lateral movement and shock loads, making them ideal for heavy-duty operations.
7. Raw Edge V-Belts
With exposed edges instead of a fabric wrap, raw edge belts grip better and deliver higher efficiency. They’re often seen in high-performance or precision applications.
What Is V-Belts Made Of?
V-belts are typically constructed from:
- Rubber or Synthetic Elastomers: The base material that provides flexibility and grip.
- Fabric Covers or Cords: Reinforcements to increase strength, stability, and reduce stretch.
- Polyester or Aramid Cords: For increased tensile strength in high-load applications.
Rubber vs Synthetic: What’s the Difference?
While rubber belts are cost-effective and flexible, synthetic V-belts (like those made from neoprene or EPDM) offer better:
- Heat resistance
- Oil resistance
- Overall lifespan
If your application involves harsh environments or fluctuating loads, synthetic might be the way to go.
What Is a Poly V-Belt?
Also known as multi-ribbed belts, Poly V-belts feature multiple longitudinal ribs for greater surface contact. They're commonly used in compact, high-speed applications (like air conditioners and conveyor systems) where space is limited but power needs are high.
