Abstract
The present invention is in the technical field of spherical roller radial bearings, more particularly, increasing the basic static and dynamic radial load ratings of a spherical roller radial bearing (100) by eliminating the cage and mounting the rollers (31) in a single row. Those spherical rollers are mounted in a full complement positioning. This new design is intended for the applications requiring higher load carrying capacity spherical roller radial bearings as compared to the same size single and double row spherical roller radial bearings, but not only limited to that purpose.
Description
DESCRIPTION
The present invention is named as Full Complement Single Row Spherical Roller Radial Bearing.
The present invention is in the technical field of spherical roller radial bearings, more particularly, increasing the basic static and dynamic radial load ratings of spherical roller radial bearings by eliminating the cage, and replacing the rollers with longer alternatives in a full complement single row.
It is given an example embodiment of the invention presented in Fig 1-6:
- Fig. 1 is a cross-sectional side view of a full complement spherical roller radial bearing of the present invention;
- Fig. 2 is a perspective view of the bearing in Fig. 1 ;
Fig. 3 is a perspective view of a spherical roller used in the bearing of Fig. 1 ;
- Fig. 4 is a partial sectional perspective view of the external ring of the bearing depicted in Fig. l ;
- Fig. 5 is a partial sectional perspective view of the internal ring of the bearing depicted in Fig. 1 ;
- Fig. 6 is a sectional view of the bearing depicted in Fig. 1.
Referring now to the invention in more detail, Fig. 1 shows the internal construction of the full complement single row spherical roller radial bearing, which is indicated by 100. The positions of the outer ring (indicated by 10), the inner ring (indicated by 20), and roller (indicated by 31). The perspective views of the bearing itself, roller, outer ring, and inner ring are depicted in Fig.2, 3, 4, and 5 respectively. Fig. 6 shows the full complement arrangement of the rollers. In the full complement arrangement, the maximum number of rollers are mounted into the space created by the raceway surfaces of inner and outer rings.
There may be some extra details such as channels, lubricating details, lubrication holes, and tapered bore on either internal and external rings, but not only limited with those details. They can also be produced for different precision classes, clearances and temperature classes, but not only limited with those alternatives. The sample drawings show a full complement spherical roller radial bearing with its lubrication detail in its outer ring.
Claims
1. The full complement single row spherical roller radial bearing is intended to be a higher load carrying capacity substitute of single row and double row spherical roller radial bearings.
2. Removing the cage holding the rollers, makes it possible to incorporate more rollers (component 31 in Fig. 1 , 2, 3, and 6) into the bearing assembly (assy 100 in Fig. 1 , 2, and 6) by using the full complement arrangement of rollers.
3. The most important component to create the load carrying capacity of a bearing is the roller.
The roller length in the full complement single row spherical roller radial bearing is selected as longer than the rollers used in the same size double row spherical roller radial bearings, due to the geometry. Since the full complement arrangement of the rollers permits the bearing to be populated with more rollers, the full complement single row spherical roller radial bearing is populated with more rollers than the same size single row spherical roller radial bearings. As the number and/or the size of the rollers incorporated into the bearing increases, the load rating values of the bearing will also increase.
4. The initial calculations showed that replacing a double row spherical roller radial bearing with an identical size, full complement single row spherical roller radial bearing, increased the basic static radial load rating, and basic dynamic radial load ratings at an amount of more than 21% and more than 29%, respectively.
5. Since this invention uses less number of rollers than the double row spherical roller radial bearings, and incorporates only one raceway into the internal ring (component 20 in Fig. 1, 2, 5, and 6) as compared to the double row spherical roller radial bearings with two raceways, the manufacturer will save labor time and machining cost.
6. The apparent advantages of the full complement single row spherical roller radial bearings were depicted above, but their advantages are not only limited to the above items.
