Description
Technical field
The utility model relates to a kind of planet wheel shaft fixed structure, belongs to speed reducer field.
Background technique
In speed reducer planetary gear transmission mechanism, planet wheel shaft adopts segmented axle construction usually, by with planet carrier interference fit and press fourth of the twelve Earthly Branches mode to fix planet wheel shaft.The deficiency that this fixed structure mainly exists has: structure is more complicated, and it is loaded down with trivial details to install difficulty, and pressure fourth of the twelve Earthly Branches structure loosely, easily lost efficacy and causes planet wheel shaft to scurry out damage speed reducer.
Summary of the invention
The technical problems to be solved in the utility model is: provide the planet wheel shaft fixed structure that a kind of structure is simple, installation is simple, stability is high, solve planet wheel shaft fixed structure more complicated, installs difficult loaded down with trivial details, pressure fourth of the twelve Earthly Branches problem loosely.
In order to solve the problems of the technologies described above, the technical solution of the utility model provides a kind of planet wheel shaft fixed structure, comprise planetary plate, planet wheel shaft is provided with in planetary plate, planet wheel shaft front end cylinder matches with inner hole of shaft sleeve, match with planetary pinion in the outside of axle sleeve, the two ends of axle sleeve are overlapped respectively and are had packing ring one, packing ring two, planet wheel shaft front end cylinder is provided with shaft block ring groove, shaft block ring is provided with in shaft block ring groove, planet wheel shaft rear end end face matches with the interior resonator end surface of planetary plate, it is characterized in that, oil groove and oilhole is provided with on described planet wheel shaft, oil groove and oilhole are interconnected, and oil groove, oilhole runs through with in planet wheel shaft.
Preferably, described planet wheel shaft is made up of the second cylinder of main body and the first cylinder of the 3rd cylinder and rear end of being located at body front end, the first inner chamber Spielpassung in first cylinder and planetary plate, the first inner chamber interference fit in second cylinder and planetary plate, the second inner chamber Spielpassung in the 3rd cylinder and axle sleeve.
Preferably, the connection orthogonal with oilhole of described oil groove, and oil groove and planet wheel shaft are coaxially arranged.
Of the present utility model rational in infrastructure compact, part is easy to process, and install simple, sound construction is stablized.The utility model changes conventional pressure fourth of the twelve Earthly Branches mode into bearing pin stepwise manner and fixes, and is both easy to fitting operation, in turn ensure that planet wheel shaft can not be scurried out damage speed reducer.
Accompanying drawing explanation
