You no longer have to accept the lower energy efficiency
associated with envelope belts on fractional horsepower
lightduty drives. Advanced V-belt technology has resulted in
the development of a cut-edge, molded cog construction which
exceeds conventional envelope belts in every performance
category except oil resistance. This has been confirmed in extensive
testing which proves that our FHP V-belts run smoother and
quieter, last longer, and substantially improve energy efficiency
compared to noncogged belts.
C og g e d f o r C oo l e r R u n n i n g
The cogged design of our FHP V-belts (standard on 4L and
5L sizes) provides a greater surface area for heat dissipation and
allows increased air flow around the belt during operation. These
factors help to reduce internal belt temperatures and greatly
improve belt life. Of course, the cogged design also improves
flexibility, an especially important consideration where minimum
or substandard sheave diameters are involved.

Low cross section vibration in rubber-edged, cogged belts reduces
noise generation. This allows you to take advantage of the longer
life and high efficiency of FHP V-belts in noise-sensitive
equipment. But even in typical factory settings, our FHP V-belts
contribute to a quieter operating environment.

The historic inefficiency of FHP drives can be traced directly
to the inability of a relatively large envelope belt to transmit a
low-power force efficiently. Transmission loss is especially
significant in factories using large numbers of drives and where
small diameter sheaves are involved. The aggregate loss can be
significant enough to have an adverse effect on equipment
performance.

• Cut-edge, molded cogged construction.
• Heat, ozone, and abrasion resistant.
These FHP V-belts efficiency begins at 93% when used
with smaller sheaves and increases dramatically as the sheave
diameter increases (Figure 1). Since more of the rated power
of the drive is delivered, actual performance nearly matches
design performance.
In addition, the efficiency of our FHP V-belts offers you the
opportunity to achieve full operating power requirements
with a lower horsepower drive, reduced energy requirements,
or both. These considerations can provide highly desirable
economic advantages whether you’re a drive manufacturer or
a drive user.
