Abstract
The utility model discloses a bearing which comprises a bearing outer ring and a bearing inner ring, wherein balls are arranged between the bearing outer ring and the bearing inner ring, the bearing inner ring is provided with one or more lubrication passages in the radial direction, one or more lubrication holes are formed in the bearing inner ring in the axial direction, the lubrication hole is communicated with the lubrication passage, and the balls adopt hollow structures. The bearing provided by the utility model has the advantages of light weight, small thermal capacitance, excellent lubrication effect, long service life and reliability, can prevent locking while prevent slipping, and is particularly suitable for the field of aviation.
Description
Technical field
The utility model relates to mechanical engineering, relates in particular to a kind of bearing.
Background technique
Development along with modern technologies, most bearing all comprises the ball between bearing inner race and bearing outer ring and the bearing enclose, and along with the growth of service time, metal balls gets rusty easily or weares and teares, cause the noise of bearing to become large, and also shortened the working life of metal balls.
A kind of bearing has appearred in the market, this bearing is provided with axis hole at bearing inner race, this bearing inner race is provided with oilhole along axle, bearing inner race radially is provided with oil duct, and oilhole communicates with oil duct, and communicates with the outer side wall of shaft hole inner wall and bearing inner race, axle is inserted axis hole, add oil in the oilhole, oil flows into shaft hole inner wall and ball position by passage, and the good bearing operation noise of moisturizing effect is low.But the bearing ball of this structure is solid construction, and quality is large, and thermal capacity is large, easily occurs " killing " phenomenon during use.
The model utility content
The utility model provides a kind of lighter weight in order to overcome the deficiencies in the prior art, and thermal capacity is less, is not prone to the bearing of " killing " phenomenon.
To achieve these goals, the utility model is by the following technical solutions: a kind of bearing, comprise outer race and bearing inner ring, be provided with ball between described outer race and the bearing inner ring, this bearing inner ring radially is provided with at least one lubricated road, bearing inner ring is provided with a lubrication hole vertically, and this lubrication hole is connected with lubricated road, and described ball is hollow-core construction.
As preferably, the internal surface of described outer race comprises a plurality of circular arc-shaped recess that connect successively.
As preferably, described circular arc-shaped recess is 3-6, and is distributed on the internal surface of described outer race.
As preferably, described lubrication hole is 4-6.
As preferably, described lubrication hole equates with the radius in lubricated road.
In sum, the utlity model has following advantage: lightweight, thermal capacitance is little, high lubricating effect, anti-slip also prevents stuck simultaneously, long service life and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is carried out clear, complete description.
As shown in Figure 1, a kind of bearing comprises outer race 1 and bearing inner ring 2, is provided with ball 7 between described outer race 1 and the bearing inner ring 2, this bearing inner ring 2 radially is provided with at least one lubricated road 6, bearing inner ring 2 is provided with a lubrication hole 5 vertically, and this lubrication hole is circular, and lubrication hole 5 is connected with lubricated road 6, described ball 7 is hollow-core construction, this structure has been saved resource, has alleviated weight and the thermal capacity of rolling bearing, avoids occuring " killing " phenomenon.
Concrete, the internal surface of described outer race 1 comprises a plurality of circular arc-shaped recess 8 that connect successively, this circular arc-shaped recess 8 only has several microns apart from original track 9, connect successively described circular arc-shaped recess 8, do not affect the rolling of ball 7, because the existence of circular arc-shaped recess 8, bearing ball 7 when high speed rotating can produce trace circular to outer race 1 in the raceway and impact between outer race 1 and bearing inner ring 2, this trace circular is impacted to be applied on the fitting surface of bearing support and outer race 1 by outer race 1 and is quite added preload to bearing, adopt the method can effectively avoid skidding, improve the working life of bearing.
Further, circular arc-shaped recess 8 is made as 3, and is evenly distributed on the interior roller surface of described outer race 1, also can be made as 4-6, can make the better effects if that prevents to skid.
The number of described lubrication hole 5 is 6 can make lubricated more even, lubricated better effects if from a plurality of holes lubricating oil filling, certainly also can be made as 4 or 5.
In order to make lubricating oil filling more convenient, described lubrication hole 5 radiuses are set to and lubricate 6 radiuses and equate.
Obviously, it is more outstanding that the bearing of this structure is applied to its advantage of aviation field, and described embodiment only is a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all should belong to the scope of the utility model protection.
