Cast Iron Belt Pulley Made in China
Belt pulley is mainly used for
long-distance power transmission, such as small diesel power output,
tractor, agricultural vehicle, and mechanical processing equipments,
agricultural machinery power transmission, air compressors,
reduction gears, generator and so on.
The material of belt pulleys
The most of belt pulleys are usually made by grey iron
ASTM A48 CL30 and CL35. They have
good corrosion resistance, wearing resistance, and it is very
strong, non-deformation, moreover, grey cast iron cost is cheap.
The ductile iron belt pulley is usually made by
ASTM A536 60-40-18 and 65-45-12
according to the strength and elongation requirements, ductile iron
is more expensive than grey iron, but it has better strength and
The type of belt pulleys
The types of belt pulley include single-slot belt pulleys,
double-slot belt pulleys, and V-belt pulley etc.
The advantages of belt pulleys
The structure of belt pulley is simple, easy to adjust. When the
belt pulley works, it is very smooth, low noise, and low vibration.
The disadvantages of belt pulleys
When the belt pulley works, it is possible happen the phenomenon of
The transmission efficiency of belt pulley is lower, and it can not
keep the accurate of transmission ratio.
The use life of the belt pulleys is short.
How to prevent belt pulley slip
Waxed belt pulley, it can increase the friction coefficient between
belt pulley and belt.
Belt pulley should be tighten, it can increase the pressure between
belt pulley and belt.
To ensure parallelism between the pulley.
The production processes of belt pulley are usually included casting
and forging. Large belt pulleys are usually made by casting process.
The materials are usually cast iron, because the casting performance
of cast iron is good. Small belt pulleys are usually made by cast
steel. Forging materials have better density, so have better
reliability and less material defects.
Since the slots of belt pulleys should be non-defective, so its
casting process is more
complex than other casting products. Only experienced
iron foundries could produce
them, especially for large cast iron belt pulleys.
