What is the principle of bearing operation
2017-05-22
Bearings
in the mechanical design has a vital, irreplaceable effect, its touch
sliding bearing size is very wide, to be able to understand that there
is no bearing, the shaft is a simple iron bar. The following principles of the operation of the bearing to do some basic introduction. Bearing
the foundation for the development of the rolling bearing, the
operating principle is to replace the sliding friction sliding friction,
generally by the two rings, a group of tumbling and a composite bearing
frame to maintain the versatility of a strong, standardized,
serialization Very high mechanical foundation pieces. Because
a variety of machinery has a different operating conditions, the
rolling bearing in the load capacity, structure and use of functions and
so on have made a variety of different requests. To this end, rolling bearings need a variety of structures. However, the most basic structure is composed of inner ring, outer
ring, tumbling body and cage - generally known as four pieces.
Bearing example
About sealed bearings, plus smoothing and sealing (or dust cover) - also known as six pieces. A variety of bearing type title is based on the title of the rolling body to the corresponding named. The
effect of various parts in the bearing are: on the radial bearing, the
inner ring and the shaft in general cooperation, and with the shaft with
the operation, the outer ring and the general casing or mechanical
shell hole into a transition, from the bearing effect. However, in some cases, there are external operations, the inner ring
from the bearing effect may be the inner ring, outer ring together with
the operation.
On
the thrust bearing, and the shaft co-operation and the same axis of the
shaft, and the bearing housing or mechanical shell hole into the
transition and support the effect of the seat ring. Rolling
(ball, roller or needle) in the bearing generally by virtue of the cage
evenly placed between the two rings for the rolling movement, its
shape, size and quantity directly affect the bearing load and use
function. Cage in addition to the trenches can be evenly separated from the
partition, but also to guide the tumbling rotation and improve the
smooth function of the bearing and other effects.
Bearing
the complexity of the type, the effect is not the same, but the
operating principle of its situation, change its case, roughly in
summary.
