Detailed Description

The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; rather than all embodiments. Based on the embodiment of the utility model; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a deep groove ball bearing's lubricated passageway, includes outer lane 1 and is provided with interference fit's inner circle 2 in outer lane 1 inside, has seted up lubricated liquid circulation chamber 3 between outer lane 1 and the inner circle 2, and lubricated liquid circulation chamber 3 includes the annular arch 4 that sets up in outer lane 1 inboard and the oil storage tank 5 of seting up in the 2 outsides of inner circle, and it has lubricating oil to fill between oil storage tank 5 and the annular arch 4.

Specifically, the annular protrusion 4 is arranged in the middle of the inner side of the outer ring 1, the annular protrusion 4 and the outer ring 1 are of an integrally formed structure, and two limiting oil grooves 6 are symmetrically formed at the lower end of the annular protrusion 4. The limiting oil groove 6 is used for preventing lubricating oil from being taken out of the lubricating liquid circulation cavity 3 under the action of centripetal force through an internal special structure when the inner ring 2 rotates.

Further, the limiting oil groove 6 comprises a cavity a601 arranged on the outer side of the lower end of the annular protrusion 4 and a cavity B602 arranged on the inner side of the lower end of the annular protrusion 4, and an oil inlet 603 is further arranged between the lower end of the cavity a601 and the upper end of the cavity B602. When the lubricating oil in the oil reservoir 5 is dispersed to the outside by the action of a centripetal force, the lubricating oil is introduced into the inside of the cavity B602 while passing through the oil inlet 603 between the cavity a601 and the cavity B602.

It is worth to be noted that, a plurality of buffer baffles 604 are staggered on the inner walls of the upper and lower sides of the cavity B602, the buffer baffles 604 are rectangular structures, and the plurality of buffer baffles 604 are annularly and equidistantly arranged and welded on the inner wall of the cavity B602. After the lubricant is introduced into the cavity B602, the flow rate of the lubricant is reduced by the buffer baffle 604 inside the cavity B602, and the lubricant is prevented from spreading out along the gap of the lubricant flow chamber 3.

It is noted that the inner ring 2 is a double-row angular contact ball bearing inner ring, the oil storage groove 5 is arranged at the position of the outer side of the inner ring 2 opposite to the annular bulge 4, and the size of the oil storage groove 5 is larger than that of the annular bulge 4. Ensuring that the bearing has sufficient lubricating oil to reduce the frictional heat between the outer ring 1 and the inner ring 2.

In addition, the outer diameter of the oil reservoir 5 is larger than the outer diameter of the cavity a601 and the inner diameter of the cavity B602, and lubricating oil is filled between the oil reservoir 5 and the cavity a 601. When the rotation of the rotary shaft is stopped, the grease flowing into the cavity B602 is again caused to flow into the oil reservoir 5 by the difference in level.

The utility model relates to a deep groove ball bearing's lubricated passageway, because there is lubricated passageway simple structure among the prior art, the function is single, the storage grease that can not be fine, make the grease follow inner circle pivoted in-process easily receive centripetal force to throw away, long-time operation will reduce the problem of lubricating oil content, therefore we are through offering lubricated liquid circulation chamber 3 between outer lane 1 and inner circle 2, and utilize spacing oil groove 6 of the protruding 4 lower extreme of annular, make the lubricating grease of oil storage tank 5 under this bearing rotation receive spacing oil groove 6 to influence not thrown away by centripetal force, avoid the bearing to rotate the phenomenon that in-process lubricating grease reduces gradually for a long time, bearing life has been prolonged, ensure that the bearing has enough moist grease of shining and is used for cooling and lubrication.

The above; is only a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; according to the technical scheme of the utility model and the improvement conception, equivalent substitution or change is carried out; are all covered by the protection scope of the utility model. Furthermore, the word "comprising" does not exclude other elements or steps, and the word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements.
