The accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation with speed reducer of the lubricating structure that the embodiment of the present invention provides.
Embodiment
The embodiment of the present invention provides a kind of lubricating structure of embedded speed reducer, has reduced the situation that lubricating structure is damaged or collides with, and then has guaranteed the proper lubrication of high-order bearing.
For the purpose, technological scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment who obtains, belong to the scope of protection of the invention.
Please refer to accompanying drawing 1, the lubricating structure of the speed reducer that the embodiment of the present invention provides comprises the lubricating oil path on the casing 4 that is opened in speed reducer, this lubricating oil path comprises all oil inlet passage 1 and the oil discharge passage 2 that the cavity between the Internal and external cycle with the high-order bearing 5 of speed reducer is connected, oil inlet passage 1 has filler opening 11, oil discharge passage 2 has oil outlet 21, and oil inlet passage 1 and the interior oiling agent that can enter high-order bearing 5 that all is filled with of oil discharge passage 2.It should be noted that, above-mentioned high-order bearing 5 is for being positioned at the bearing at place, high position on speed reducer; Concrete, when the speed reducer shown in figure adopts left side to install higher than the inclination mode on right side, high-order bearing 5 is for being arranged on the bearing in rotating shaft 3 left sides in figure, and the bearing of opposite side is low level bearing 7.
During application, by filler opening 11 to the interior injection oiling agent of oil inlet passage 1, until oiling agent is filled with in the whole lubricating cavity of high-order bearing 5, the cavity between the Internal and external cycle of high-order bearing 5 namely; The present embodiment can be observed from oil outlet 21 height of oiling agents, stops oiling during higher than the extreme higher position of high-order bearing 5 when oiling agent.
The embodiment of the present invention is injected oiling agent by the lubricating oil path on the casing 4 to being opened in speed reducer, and this oiling agent is entered in the cavity between the Internal and external cycle of high-order bearing 5, and then has realized lubricated to high-order bearing 5.Because above-mentioned lubricating oil path is opened on casing 4, so lubricating structure of the present invention can not expose to casing 4, that is to say that this lubricating structure is embedded in casing 4, reduced the situation that lubricating structure is damaged or collides with, and then guaranteed the proper lubrication of high-order bearing 5.
In addition, the lubricating structure of the embodiment of the present invention has also saved complicated lubricating pipe, simple in structure, is convenient to manufacturing.
In a kind of specific embodiment of the present invention, above-mentioned oil inlet passage 1 is communicated with the low level side (namely being positioned at a side of lower position) of high-order bearing 5, and oil discharge passage 2 is communicated with the high-order side (namely being positioned at a side of high position) of high-order bearing 5.Now oil inlet passage 1 and oil discharge passage 2 lay respectively at the both sides of high-order bearing 5, in the process of injecting oiling agent, can guarantee that the oiling agent in oil inlet passage 1 enters oil discharge passage 2 along the axial of high-order bearing 5 again through after whole lubricating cavity, and then guaranteed that whole lubricating cavity all is filled with oiling agent, thereby guaranteed lubrication effect.Certainly, above-mentioned oil inlet passage 1 can also be communicated with the high-order side of high-order bearing 5, or oil inlet passage 1 and oil discharge passage 2 all are communicated with the high-order side of high-order bearing 5.
