Abstract
The utility model relates to a lubrication structure for a superspeed angular contact bearing pack, which comprises a superspeed angular contact bearing pack, and is characterized in that an outer spacer bush is arranged between superspeed angular contact bearings and is provided with an oil-filling semi-counter bored hole, the bottom of the oil-filling semi-counter bored hole is provided with an oil spray nozzle, the outlet of the oil spray nozzle corresponds to the slope of the inner ring of the superspeed bearing arranged on the side of the outer spacer bush, and the contact angle of the oil spray nozzle and the horizontal line corresponds to the slope of the inner ring of the bearing by 30 degrees. The utility model has the advantages that since the lubricating oil is jetted into the bearing by a high-pressure jet, and the flow of the lubricating oil is large during the jetting, dust and cutting liquid can not enter the bearing, so the bearing can not be damaged due to burning, in addition, the jetted oil can bring away heat, the temperature rise of the bearing can be controlled, the noise of the bearing is reduced and the service life of the bearing is obviously improved.
Description
Technical field
The utility model relates to a kind of lubricating structure of bearing, particularly a kind of lubricating structure that is used for ultra high speed angular contact bearing group.
Background technique
Conventional at present lubricated oil mist lubrication and the oil-air lubrication of being generally, and the ultra high speed bearing when rotated, rolling element and retainer are also with quite high rotational speed, make surrounding atmosphere form air-flow, this lubricating system is difficult to lubricant oil is delivered in the bearing, thereby bearing is when ultra high speed is rotated, owing to being subjected to less than the good lubricated high temperature that produces, increase the bearing noise, reduced the working life of bearing, therefore needing to demand a kind of new lubricating structure that is used for the ultra high speed angular contact bearing of invention urgently, to solve the lubrication problem of present ultra high speed angular contact bearing.
Summary of the invention
The purpose of this utility model is to solve ultra high speed angular contact bearing in the prior art to utilize oil mist lubrication and the existing difficulty of oil-air lubrication that lubricant oil is delivered to problem in the bearing, and a kind of lubricating structure that is used for ultra high speed angular contact bearing group is provided.A kind of lubricating structure that is used for ultra high speed angular contact bearing group of the utility model design, comprise the ultra high speed bearing pack, it is characterized in that: between the ultra high speed bearing, be provided with outer separator, on outer separator, offer oiling half counterbore, bottom at oiling half counterbore is provided with oil nozzle, and the outlet port of oil nozzle is with respect to the bearing inner race slope of the ultra high speed bearing that is positioned at the outer separator avris.Oil nozzle and horizontal line with 30 ° wrapping angle with respect to the bearing inner race slope.The method that the utility model has the advantages that high-pressure injection is ejected into lubricant oil in the bearing, and the flow when spraying because of lubricant oil is big, and dust and cutting fluid can not enter bearing, the unlikely bearing that burns.And heat is taken away in the oil spout meeting, the bearing temperature rise may command.Reduced the bearing noise, bearing life improves significantly.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise the ultra high speed bearing pack among the figure, it is characterized in that: between ultra high speed bearing 1, be provided with outer separator 2, on outer separator 2, offer oiling half counterbore 3, bottom at oiling half counterbore 3 is provided with oil nozzle 4, and the outlet port of oil nozzle 4 is with respect to the bearing inner race slope 5 of the ultra high speed bearing 1 that is positioned at outer separator 2 avris.Oil nozzle 4 and horizontal line with 30 ° wrapping angle with respect to bearing inner race slope 5.
The lubricated of ultra high speed bearing 1 is to have utilized high pressure that oiling half counterbore 3 of lubricant oil from outer separator 2 is pressed into when assembling in pairs, penetrate through oil nozzle 4 then, lubricant oil is sprayed onto on the bearing inner race slope 5 of ultra high speed bearing 1, and be not directly injected on the steel ball, to reduce vibration and noise.When oil nozzle 4 becomes 30 ° wrapping angle with horizontal line is best, also can change according to operating mode.Be not difficult to find out that from figure oil can be taken away impurity and cutting fluid fast during bearing operation under effect at a high speed, reduce temperature.So the lubricated of bearing obtained reliable assurance, thereby improved effectively the life-span of bearing.
Claims (2)
1, a kind of lubricating structure that is used for ultra high speed angular contact bearing group, comprise the ultra high speed bearing pack, it is characterized in that: between the ultra high speed bearing, be provided with outer separator, on outer separator, offer oiling half counterbore, bottom at oiling half counterbore is provided with oil nozzle, and the outlet port of oil nozzle is with respect to the bearing inner race slope of the ultra high speed bearing that is positioned at the outer separator avris.
2, by the described a kind of lubricating structure that is used for ultra high speed angular contact bearing group of claim 1, it is characterized in that: oil nozzle and horizontal line with 30 ° wrapping angle with respect to the bearing inner race slope.
