Rubber V-belts have a v-shaped profile and hence the name. There are many
variations of the v-belt. Most of the V-belts are either standard or
inverted. A rubber V-belt is a continuous band for transferring power or
conveying materials from one shaft or wheel to another and these belts have
several benefits compared to the other drive systems. They provide an
additional amount of stretch which is not the case with other belts. The
belts are able to work smoothly and quietly, without the requirement of
lubrication. This is an important feature of rubber V- belts.
Rubber V-belts are available in different sizes and types and are suitable
for a wide range of applications. They have the capability of accommodating
a wide range of horse power speeds and outputs which exist in the industrial
drive systems.
Buying Tips
Following are certain specifications of V-Belts:
- Tensile Strength: To withstand maximum load or
stress without any damage and it is measured as the ratio of maximum
load to the cross sectional area of the belt.
- Operating Speed: The maximum working speed of
the rubber V-belt.
- Operating Temperature: The temperature range at
which the belt is designed to operate properly without any damage.
- Material of Construction: This is to select the
type of rubber required to produce the belts.
- Length: The cross sectional length of the top
flat portion of the V-belt.
- Width: It is the overall width of the V-belt.
The effective width should be considered while selecting the belt
for a specific drive mechanism.

Types of rubber used in rubber V-belts
- Natural Rubber
- Neoprene
- Polyurethane
- Butyl Rubber (IIR)
- Ethylene Propylene Diene Monomer (EPM, EPDM)
- Chloroprene rubber
- Urethane
Types of V-Belts
- Raw Edged V-Belts: They are used when there is the
chance of constant slippage of the other V-belts.
- Narrow V-Belts: They have a narrower pitch width
when they are compared to the other types of V-belts.
- Ribbed V-Belts: These belts consist of two or more
V-like formations which are placed next to one another and the cross
sectional picture looks rather like a multiple W-Belt.
- Classic V-Belts: It is a single V shaped belt
without any ribs or raw edges.
Advantages
- Easy installation
- Large speed ratio is permitted
- Long life
- Operation is quiet
- Maintenance is low
- Easy removal
- Flexible
- Vibration is low
