The role of the cage and structural characteristics
Imported bearing (especially the rolling bearing) is the zonal cage and maintains the structure of the two. One of the large imported bearing general requirements under high load, often without a cage, but full of rolling element between the inner and outer raceway. While most of the small and medium-sized imported rolling bearings are with cage.
The bearing in the machining process, import bearing outer ring, inner ring, rolling body and is how to a cage. Simple speaking, is the first imported bearing inner and outer ring, inner ring road, and then put a rolling body (aside), and then adjust the rolling body position, in the end, put the cage.
Now everyone knows, is in the process of processing of imported bearing cage, then import bearing cage's main exactly is what effect?
The role of the cage as follows:
1, guide and drive in the right rolling on the rolling roller;
2, keep to separate rolling body equidistance, uniformly distributed in the race on the circumference of a circle in order to prevent the mutual collision and friction between the work roll body;
3, in the separated type bearings, the rolling body and a ring together, in order to prevent the rolling body fall off.
Bearing called window, used to isolate and guide roller, the cage pocket hole clearance has certain activity in radial and axial, radial each.the called cage clearance. In roller cage has a variety of structural types, complicated shape. Keep on many equidistance hole, hole shape is spherical, tooth type, such as round, oval, rectangular, and its size is greater than the rolling body size, the difference between the two for the pocket hole clearance, sometimes on imported rolling keep part of the connection of the frame window is called the lintel, it ACTS as connection and increase strength of cage.
