Abstract
The present invention relates to a kind of full-complement cylinder roller bearing.Including outer ring, inner ring, rolling element, interior loose rib and outer loose rib, raceway is respectively arranged with outer ring and inner ring, rolling element is installed in the raceway between outer ring and inner ring, the outside diameter of outer loose rib and the rib internal diameter of outer ring are interference fitted, one middle side part processes a ring annular groove, rolling element both sides are machined with the protrusion of cylinder, are engaged with annular groove；The outside diameter of interior loose rib and the centre rib internal diameter of outer ring are interference fitted, and both sides process a ring annular groove, coordinated with the projection portion of rolling element.Self-locking is not required in roller of the present invention, even if removing inner ring, roller will not be scattered, and easily makes bearing heating additionally, due to self-locking, and a kind of full-complement cylinder roller bearing invented herein can bear the temperature of higher, and bearing operation is more steady.
Description
Technical field
The present invention relates to field of bearings, and in particular to novel full complement Biserial cylindrical roller bearing.
Background technology
Completely dress Biserial cylindrical roller bearing is different from common bearing, which can accommodate more rollings without retainer
Son, compared with other identical cylinder roller bearings of size, can bear larger radial load；, can be with and radial section is small
Space is saved, therefore, such product is widely used in the occasion of low-speed heave-load, such as the output terminal of gear reducer, pulley blocks wheel axle portion
Grade.
Full-complement cylinder roller bearing currently on the market for prevent roller be scattered etc. reason need it is real during installation
The self-locking of existing roller, roller self-locking can cause bearing easily to generate heat, so that bearing is easy in prolonged hot environment
Heat fatigue is produced, reduces service life.
The content of the invention
The present invention provides a kind of new full dress Biserial cylindrical roller bearing, so that it is easy to solve the roller when removing inner ring
It is scattered and due to caused by roller self-locking the problem of Bearing Temperature.
The present invention is that technical solution is to provide full dress Biserial cylindrical roller bearing used by solving its technical problem, including
Outer ring, inner ring, rolling element, interior loose rib and outer loose rib, raceway, rolling element peace are respectively arranged with the outer ring and inner ring
In raceway between outer ring and inner ring, the outer loose rib is arranged on rolling element close to the side of bearing face, and its
Outside diameter and the rib internal diameter of outer ring are interference fitted, and the side surface that outer loose rib is contacted with rolling element is machined with a ring annular groove,
The protrusion of cylinder is all machined with rolling element both sides, is engaged with annular groove；The interior loose rib is arranged on the rolling of two row
Between kinetoplast, and its outside diameter and the centre rib internal diameter of outer ring are interference fitted, and the both side surface that interior loose rib is contacted with rolling element is equal
A ring annular groove is machined with, is coordinated with the projection portion of rolling element.
Beneficial acquired by the present invention has the technical effect that：
When mounted, self-locking is not required in roller to the full dress Biserial cylindrical roller bearing of the present invention, even if removing inner ring, roller is not yet
It can be scattered, because outer loose rib plays supporting role with interior loose rib to roller.Easily make bearing heating additionally, due to self-locking,
Therefore the more common full-complement cylinder roller bearing of this structure invented herein can bear the temperature of higher, and bearing operation is more steady.
Brief description of the drawings
Fig. 1 completely fills Biserial cylindrical roller bearing structure diagram for the present invention.
Fig. 2 structure partial enlarged drawings of the present invention：（a）Outer loose rib position partial enlarged view；（b）Interior loose rib position is local
Enlarged drawing.
Wherein, 1, outer ring, 2, inner ring, 3, rolling element, 4, interior loose rib, 5, outer loose rib.
Embodiment
Below in conjunction with attached drawing and specific embodiment, the present invention is further illustrated.
As shown in Figure 1 Biserial cylindrical roller bearing structure diagram is completely filled for the present invention.Including outer ring 1, inner ring 2, rolling element
3rd, interior loose rib 4 and outer loose rib 5, are respectively arranged with raceway on the outer ring 1 and inner ring 2, rolling element 3 is installed on outer ring 1
In raceway between inner ring 2.
It is illustrated in figure 2 structure partial enlarged drawing of the present invention.（a）For outer loose rib position partial enlarged view.Described is outer
The outside diameter of loose rib 5 and outer ring（1）Rib internal diameter interference fit, positioned；One middle side part processes a ring annular groove.Roll
Body 3 is machined with a cylindrical protrusion compared with common cylinder rolling element, in 3 both sides of rolling element, can be with outer loose rib 5
Annular groove is engaged installation.
Figure（b）For interior loose rib position partial enlarged view.In the outside diameter of the interior loose rib 5 and the centre rib of outer ring 1
Footpath is interference fitted, and is positioned；Both sides process a ring annular groove, and cooperation installation is carried out with the projection portion of rolling element 3.
When mounted, self-locking is not required in roller to the full-complement cylinder roller bearing of the present invention, even if removing inner ring, roller is not yet
It can be scattered, because outer loose rib plays supporting role with interior loose rib to roller.Easily make bearing heating additionally, due to self-locking,
Therefore the more common full-complement cylinder roller bearing of this structure invented herein can bear the temperature of higher, and bearing operation is more steady.
