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
