Introduction to the Vibrating screen bearings
Mainly used in mine vibration mechanical equipment, vibrating
screen machine and vibrating motor, which is one of the most
important parts of such equipment. The bearing operating condition
is very bad, not only the environment humidity is big, the dust
particle is much, the speed is high, the temperature is high, and
has the strong vibration impact, causes the work load is very big.
The bearing has strong bearing capacity, good impact resistance,
high reliability, good lubrication performance, and can overcome
the deflection of the shaft.
The characteristics of
1. Vibrating screen bearings are generally symmetrical aligning
roller and cylindrical roller;
2. Generally speaking, the size tolerance is P6, and the operating
tolerance is P5. The tolerance is fixed, but there is a British
system and a metric system.
3. Because of the high heat, a large gap was selected. But the gap
can be calculated, mainly considering the original clearance,
tolerance and temperature rise can be calculated;
4. The application requirements of vibrating screen bearings are
very high, and the materials of plain bearing steel are not
acceptable. The cage is made of machined brass and is guided by the
outer ring to apply to the case of eccentricity loads!
