Abstract
A kind of ultra high speed rolling bearing, relate to technical field of bearings, comprise mesosphere (1), bearing outer ring (3), bearing inner race (6), outer ring rolling element (2), inner ring rolling element (4) and spacer ring (5), in the outside of mesosphere (1), be provided with bearing outer ring (3), described outer ring rolling element (2) is arranged in the raceway between bearing outer ring (3) internal surface and mesosphere (1) outer surface, in the both sides, inside of mesosphere (1), be respectively equipped with bearing inner race (6), between the bearing inner race (6) of both sides, be provided with spacer ring (5), both sides at mesosphere (1) internal surface are respectively equipped with interior raceway, described interior raceway forms two raceways with the outer raceway of two bearing inner races (6) outer surface respectively, described inner ring rolling element (4) is separately positioned in two raceways, it is steady that the utility model has been realized bearing rotary, can adapt to the object of ultra high speed working condition.
Description
[technical field]
The utility model relates to technical field of bearings, and specifically the utility model relates to a kind of ultra high speed rolling bearing.
[background technique]
Known, development along with high speed, high-precision technology, high speed performance to bearing is had higher requirement, the ultra high speed technical field of using at bearing, traditional bearing can not meet the needs of working condition, provides a kind of and can surpass the basic demand that the bearing that meets Super High Speed Condition becomes those skilled in the art.
[summary of the invention]
In order to overcome the deficiency in background technique, the utility model discloses a kind of ultra high speed rolling bearing, realized bearing rotary steady, can adapt to the object of ultra high speed working condition.
For realizing above-mentioned model utility object, the utility model adopts following technological scheme:
A kind of ultra high speed rolling bearing, comprise mesosphere, bearing outer ring, bearing inner race, outer ring rolling element, inner ring rolling element and spacer ring, outside at mesosphere is provided with bearing outer ring, described outer ring rolling element is arranged in the raceway between bearing outer ring internal surface and mesosphere outer surface, both sides, inside at mesosphere are respectively equipped with bearing inner race, between the bearing inner race of both sides, be provided with spacer ring, in the both sides of mesosphere internal surface, be respectively equipped with interior raceway, described interior raceway forms two raceways with the outer raceway of two bearing inner race outer surfaces respectively, described inner ring rolling element is separately positioned in two raceways.
Described ultra high speed rolling bearing, the bearing inner race arranging respectively in the both sides, inside of mesosphere is for be arrangeding in parallel.
Described ultra high speed rolling bearing, the axis that is separately positioned on two inner ring rolling elements in raceway is located on the same line.
Described ultra high speed rolling bearing, described outer ring rolling element and inner ring rolling element are high speed ceramic ball.
Described ultra high speed rolling bearing, the diameter of described outer ring rolling element is than the diameter of inner ring rolling element large 10%.
Owing to having adopted technique scheme, the utlity model has following superiority:
Ultra high speed rolling bearing described in the utility model, in the both sides, inside of mesosphere 1, two bearing inner races 6 are set respectively, spacer ring 5 is set between two bearing inner races 6, has effectively strengthened whole antiwhip, thereby met the requirement of high speed machine high speed; Outer ring rolling element (2) and inner ring rolling element (4) rolling element are all set to high speed ceramic ball, ability and the bearing load carrying capacity of the anti-alternate load of bearing have greatly been improved, and the ceramic ball friction Temperature Rise that is in operation is less, quality is light, when ultra high speed turns round, the suffered centrifugal force of rolling element and gyrostatic moment are little, and revolving sliding is little, so frictional loss is less; And rolling element 2 diameters in outer ring are greater than inner ring rolling element 4 diameters, impel inside and outside rolling element assembly friction torque close, increase the stationarity that bearing rotates; Mesosphere (1) is the outer raceway of inner ring rolling element (4), is again the interior raceway of outer ring rolling element (2), can to bearing, apply pretightening force by adjusting the length of spacer ring (5).
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
In the drawings: 1, mesosphere; 2, outer ring rolling element; 3, bearing outer ring; 4, inner ring rolling element; 5, spacer ring; 6, bearing inner race.
[embodiment]
By the following examples, can explain in more detail the utility model, the utility model is not limited to the following examples;
Ultra high speed rolling bearing described in 1 by reference to the accompanying drawings, comprise mesosphere 1, bearing outer ring 3, bearing inner race 6, outer ring rolling element 2, inner ring rolling element 4 and spacer ring 5, in the outside of mesosphere 1, be provided with bearing outer ring 3, described outer ring rolling element 2 is arranged in the raceway between bearing outer ring 3 internal surface faces and mesosphere 1 outer surface, both sides, inside at mesosphere 1 are respectively equipped with bearing inner race 6, and the bearing inner race 6 arranging respectively in the both sides, inside of mesosphere 1 is for be arrangeding in parallel; Between the bearing inner race 6 of both sides, be provided with spacer ring 5, both sides at mesosphere 1 internal surface are respectively equipped with interior raceway, described interior raceway forms two raceways with the outer raceway of two bearing inner race 6 outer surfaces respectively, described inner ring rolling element 4 is separately positioned in two raceways, the axis that is separately positioned on two inner ring rolling elements 4 in raceway is located on the same line, and described outer ring rolling element 2 and inner ring rolling element 4 are high speed ceramic ball; The diameter of described outer ring rolling element 2 is than the diameter of inner ring rolling element 4 large 10%.
The utility model does not describe part in detail for prior art.
The embodiment who selects in this article in order to disclose goal of the invention of the present utility model, currently thinks suitablely, still, will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the embodiment within the scope of this design and model utility.
