Abstract
The utility model discloses one kind completely filling Biserial cylindrical roller bearing.Including outer ring, inner ring, rolling element, interior loose rib and outer loose rib, it is respectively arranged with raceway on outer ring and inner ring, rolling element is mounted in the raceway between outer ring and inner ring, the outer 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 cylindrical protrusion, are matched with annular groove；The outer 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.The utility model roller does not need self-locking, even if removing inner ring, roller will not be scattered, and is easy to make bearing heating, a kind of full-complement cylinder roller bearing of the utility model that can bear higher temperature additionally, due to self-locking, bearing operation is more stable.
Description
Technical field
The utility model is related to field of bearings, and in particular to a kind of 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 can bear larger radial load compared with other identical cylinder roller bearings of size；And radial section is small, and it can be with
Space is saved, therefore, such product is widely used in the occasion of low-speed heave-load, such as the output end of speed reducer, pulley blocks wheel axle portion
Grade.
Full-complement cylinder roller bearing currently on the market be prevent roller be scattered etc. reasons need it is real during installation
The self-locking of existing roller, roller self-locking can make bearing be easy fever, so that bearing is easy in prolonged hot environment
Heat fatigue is generated, service life is reduced.
Invention content
The utility model provides a kind of novel full dress Biserial cylindrical roller bearing, to solve the roller when removing inner ring
It is easy to be scattered and due to caused by roller self-locking the problem of Bearing Temperature.
The utility model is that technical solution used by solving its technical problem is to provide and a kind of completely filling double-row cylindrical roller
Bearing, including outer ring, inner ring, rolling element, interior loose rib and outer loose rib are respectively arranged with rolling on the outer ring and inner ring
Road, rolling element are mounted in the raceway between outer ring and inner ring, and the outer loose rib is arranged in rolling element close to bearing face
Side, and its outer 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
One ring annular groove is all machined with cylindrical protrusion in rolling element both sides, is matched with annular groove；The interior loose rib is set
It sets between two row rolling elements, and its outer diameter and the centre rib internal diameter of outer ring are interference fitted, what interior loose rib was contacted with rolling element
Both side surface is machined with a ring annular groove, is coordinated with the projection portion of rolling element.
Beneficial acquired by the utility model has the technical effect that：
One kind of the utility model completely fills Biserial cylindrical roller bearing when mounted, and roller does not need self-locking, even if removing
Inner ring, roller will not be scattered, because outer loose rib plays supporting role with interior loose rib to roller.Hold additionally, due to self-locking
Easily make bearing heating, therefore the more common full-complement cylinder roller bearing of this structure of this paper utility models can bear higher temperature
Degree, bearing operation are more stable.
Description of the drawings
Fig. 1 is that the utility model one kind completely filling Biserial cylindrical roller bearing structure diagram.
Fig. 2 a are the utility model China and foreign countries loose rib position partial enlarged view；Fig. 2 b are interior loose rib portion in the utility model
Position partial enlarged view.
Wherein, 1, outer ring, 2, inner ring, 3, rolling element, 4, interior loose rib, 5, outer loose rib.
Specific implementation mode
The utility model is further described below in conjunction with attached drawing and specific embodiment.
As shown in Figure 1 Biserial cylindrical roller bearing structure diagram is completely filled for the utility model one kind.Including outer ring 1, inner ring
2, rolling element 3, interior loose rib 4 and outer loose rib 5, raceway is respectively arranged on the outer ring 1 and inner ring 2, and rolling element 3 is installed
In raceway between outer ring 1 and inner ring 2.
As shown in Figure 2 a, it is the utility model China and foreign countries loose rib position partial enlarged view.The outer diameter of the outer loose rib 5
With outer ring（1）Rib internal diameter interference fit, positioned；One middle side part processes a ring annular groove.Rolling element 3 and common circle
Column rolling element is compared, and in 3 both sides of rolling element, processing can match there are one cylindrical protrusion with the annular groove of outer loose rib 5
Close installation.
Fig. 2 b are interior loose rib position partial enlarged view in the utility model.The outer diameter of the interior loose rib 5 and outer ring 1
Centre rib internal diameter interference fit, positioned；Both sides process a ring annular groove, are matched with the projection portion of rolling element 3
Close installation.
When mounted, roller does not need self-locking to a kind of full-complement cylinder roller bearing of the utility model, even if removing inner ring,
Roller will not be scattered, because outer loose rib plays supporting role with interior loose rib to roller.It is easy to make additionally, due to self-locking
Bearing heating, therefore the more common full-complement cylinder roller bearing of this structure of the utility model can bear higher temperature, bearing
It runs more stable.
