Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art with reference to explanation
Book word can be implemented according to this.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other element or combinations.
Fig. 1 ~ 3 show a kind of planetary gear for planetary reducer of the utility model, including：
Matrix 1, middle part are provided with a bearing hole 2；1 surface middle part of described matrix is provided with one for filling the annular of lubricating oil
Oil trap 3；1 exterior circumferential of described matrix is equipped with gear part 4；The gear part 4 includes tooth socket 41, tooth top 42 and base portion 43, institute
It states 4 base portion 43 of gear part and is provided with oil canal 1, the oil canal 1 is communicated with the annular oil trap 3, the oil canal 1
Top is equipped with an elastic element 6, and the elastic element 6 protrudes from 4 tooth socket of gear part, 41 surface；41 both ends of tooth socket
42 side wall of tooth top is equipped with the oil outlet 51 communicated with the oil canal 1；6 bottom of elastic element is fixedly connected with a company
Bar 61,61 other end of connecting rod are fixedly connected with a cylinder block 7；The annular oil trap 3 is towards the bearing hole 2 one
Side is equipped with oil canal 28；The oil canal 28 includes rectangular cavity 81 and the cylindrical cavity 82 to match with 7 shape of block；Institute
81 length of side of rectangular cavity is stated more than 82 diameter of cylindrical cavity；The block 7 is located at the oil canal 28 and the annular oil trap
3 connectivity parts；2 inner wall of bearing hole offers oil outlet 21, the oil outlet 21 and 28 rectangular cavity of oil canal, 81 phase
It is logical.
In this technical solution, when planetary reducer works, during planetary gear rotation, 41 surface of tooth socket
The elastic element 6 is moved by with the gear external force that the tooth socket 41 is engaged to the oil canal 1, positioned at the oil canal
Lubricating oil in one 5 is flowed to both sides, and the oil outlet 51 through the 42 side wall both ends of tooth top flows out, and reaches lubrication, described in cooling
