Abstract

The utility model relates to the technical field of a self-aligning ball bearing, in particular to a centripetal double-layer self-aligning ball bearing. The centripetal double-layer self-aligning ball bearing comprises an outer ring, an inner ring, rolling bodies and a retainer, wherein outer-layer rolling bodies and inner-layer rolling bodies are arranged between the outer ring and the inner ring, and the inner diameter of the outer-layer rolling bodies is larger than that of the inner-layer rolling bodies. A bearing middle sleeve is additionally arranged between the outer-layer rolling bodies and the retainer. According to the double-layer self-aligning ball roller pin, the rotating speed of each row of rolling bodies is sharply declined, and the friction coefficient is greatly reduced. The double-layer self-aligning ball roller pin has high bearing capability, reasonable design and long service life and can reply different load bearing requirements.

Description

Double-deck selfaligning ball bearing
Technical field
The utility model relates to the selfaligning ball bearing technical field, especially a kind of entad double-deck selfaligning ball bearing.
Background technique
Bearing all is able to use widely on some equipment of all trades and professions and utensil, practical situations such as load of estimating to carry to structural feature, the bearing of equipment and Environmental Conditions, and it is varied that the kind model of bearing also appears, complete.When common selfaligning ball bearing carried high speed rotating, the outer footpath of roller one end was different with inner footpath one end rotating speed sometimes, and it is bigger to wear and tear, and has a strong impact on working life.
The model utility content
The technical problem that the utility model will solve is: for overcoming the above problems, the entad double-deck selfaligning ball bearing of a kind of long-life, high-mechanic is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of double-deck selfaligning ball bearing; Comprise the outer ring, inner ring, rolling element and retainer; Outer rolling element and internal layer rolling element are housed between outer ring and the inner ring, and the internal diameter of outer rolling element is greater than the internal layer rolling element.Add the bearing middle cover between outer rolling element and the retainer.Internal layer rolling element and retainer thereof are contained on the recessed raceway of internal surface of recessed raceway and middle cover on the outer surface of bearing inner race, and outer rolling element and retainer thereof are contained on the recessed raceway of outer surface of recessed raceway and middle cover on the internal surface of bearing outer ring.
The beneficial effect of the utility model is, the double-deck spherical ball needle roller of the utility model makes the rotating speed of every row's rolling element descend greatly, and friction factor reduces greatly, and bearing capacity is high, and is reasonable in design, can tackle different burden requirements, long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. outer rings among the figure, 2. inner ring, 3. outer rolling element, 4. internal layer rolling element, 5. retainer.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of double-deck selfaligning ball bearing as shown in Figure 1 comprises outer ring 1, inner ring 2, and rolling element and retainer 5 are equipped with outer rolling element 3 and internal layer rolling element 4 between outer ring 1 and the inner ring 2, and the internal diameter of outer rolling element 3 is greater than internal layer rolling element 4.Add the bearing middle cover between outer rolling element 3 and the retainer 5.Internal layer rolling element 4 and retainer 5 thereof are contained on the recessed raceway of internal surface of recessed raceway and middle cover on the outer surface of bearing inner race 2, and outer rolling element 3 and retainer 5 thereof are contained on the recessed raceway of outer surface of recessed raceway and middle cover on the internal surface of bearing outer ring.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
