SINOCONVE Automotive Raw Edge Cogged V Belt for Fan & Engine Drive Systems

Flexible Raw Edge Cogged V Belt for Automotive Drives

The SINOCONVE automotive raw edge cogged V belt is designed for fan, alternator, pump, compressor and other accessory drive systems where a conventional V-groove transmission requires improved flexibility.

Molded cogs are formed on the inner side of the belt to reduce bending resistance. This allows the belt to wrap more easily around smaller pulleys while the raw V-shaped sidewalls maintain frictional contact with the pulley grooves to transfer power.

Cogged V Belt Is Not a Timing Belt

The grooves or “cogs” visible on the inside of this belt can make it look similar to a toothed timing belt, but the two products use different transmission principles.

Why Use a Cogged V-Belt?

Available Cogged V-Belt Profiles

SINOCONVE supplies multiple raw edge cogged V-belt families for different pulley sizes, transmission loads and equipment layouts.

The current SINOCONVE cogged V-belt range includes 9.5X, AX, BX, CX, XPZ, XPA, XPB, XPC, 3VX, 5VX and 8VX configurations.

Raw Edge Cogged V-Belt Construction

Automotive Fan and Accessory Drive Applications

Cogged V-belts are widely used in vehicle and mechanical accessory systems where V-groove transmission remains part of the drive design.

• Cooling fan drives
• Alternator drives
• Water pump drives
• Air-conditioning compressor drives
• Auxiliary engine systems
• Automotive replacement markets
• Industrial fans
• Pumps and compressors
• General machinery power transmission

Raw Edge Cogged vs. Wrapped V Belt

Both products use V-groove friction for power transmission, but their outer construction and flexibility differ.

How to Select the Correct Cogged V Belt

A visual match is not enough for replacement selection. Two cogged belts can look similar while using different section widths, heights or lengths.

1. Confirm the complete original belt marking.
2. Identify the V-belt profile or section.
3. Confirm the specified belt length.
4. Check pulley groove dimensions.
5. Confirm pulley diameters and center distance.
6. Record motor or engine speed.
7. Confirm transmitted power or load.
8. Check operating temperature and environmental conditions.

Check the Drive System Before Replacing the Belt

Premature V-belt wear is not always caused by the belt itself. A replacement should be combined with basic inspection of the drive system.

• Inspect V-grooves for wear or contamination.
• Check pulley alignment.
• Inspect bearings for abnormal resistance or movement.
• Confirm belt tension is within the required range.
• Check for oil, coolant or other contamination.
• Replace damaged or heavily worn mating components where necessary.

Automotive Cogged V-Belt FAQs

Why does a cogged V belt have grooves on the inside?

The molded cogs improve belt flexibility and reduce bending resistance, allowing easier operation around relatively small pulleys.

Is a cogged V belt the same as a timing belt?

No. A cogged V belt transfers power through friction between its V-shaped sidewalls and the pulley groove. A timing belt uses positive tooth engagement with a toothed pulley.

What is the advantage of a raw edge construction?

Raw V-shaped sidewalls provide direct frictional contact with the pulley groove, while the cogged body improves flexibility in the bending zone.

Can AX and BX belts be interchanged?

No. They use different cross-sectional dimensions. The belt profile must match the pulley groove and original drive specification.

Can SINOCONVE supply automotive and industrial cogged V belts together?

Mixed profiles and sizes can be reviewed according to the requested model list, quantities, marking and packaging requirements.
