Description
Technical Field
The utility model relates to a gear assembly technical field specifically is an output outer gear ring.
Background
Gear refers to a mechanical element on a rim with gears continuously engaged to transmit motion and power. The use of gears in transmissions has long emerged. At the end of the 19 th century, the principle of generating the cutting method and the successive appearance of special machine tools and cutters for cutting teeth by using the principle pay attention to the running stability of gears along with the development of production.
The output gear of the existing reduction gearbox generally adopts a two-section tooth surface structure, namely a combined structure of a section of gear shaft matched with a section of gear, in order to save materials, a sectional inserting structure is generally adopted in the prior art, and the gear shaft and the gear are assembled in a key connection mode after being distributed and processed, but the structure still has the problems of troublesome assembly and low installation efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.
An output external gear ring comprises an output gear and a wheel shaft inserted into the axis of the output gear, wherein the axis of the output gear is provided with a prismatic through hole, and the wheel shaft is provided with a prism matched with the through hole in shape and inserted into the through hole through the prism to be tightly matched with the through hole; one end of the wheel shaft is a supporting shaft, and the other end of the wheel shaft is a connecting shaft and a key groove is formed in the connecting shaft.
Furthermore, oil storage grooves and oil passing holes for communicating the two oil storage grooves are respectively arranged on two end faces of the output gear.
Furthermore, one end of the wheel shaft close to the supporting shaft is provided with a driving gear shaft.
Furthermore, a sealing ring groove is arranged on the supporting shaft.
Compared with the prior art, the utility model discloses the beneficial effect who gains does: the utility model has novel structure, adopts the split splicing assembly mode, is convenient for processing the tooth surface, saves production materials and saves cost; and a prismatic structure is adopted, so that the key insertion installation is avoided, the assembly procedure is optimized, and the stability of the assembly structure is improved.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, an output external gear ring includes an output gear 1 and a wheel shaft 2 inserted into the axis of the output gear 1, wherein the axis of the output gear 1 is provided with a prismatic through hole 11, the wheel shaft 2 is provided with a prism 21 matched with the through hole 11 in shape, and the prism 21 is inserted into the through hole 11 and is tightly fitted with the through hole 11; one end of the wheel shaft 2 is a support shaft 22, the other end is a connecting shaft 23, and a key groove 231 is arranged on the connecting shaft 23. The utility model has novel structure, adopts the split splicing assembly mode, is convenient for processing the tooth surface, saves production materials and saves cost; and a prismatic structure is adopted, so that the key insertion installation is avoided, the assembly procedure is optimized, and the stability of the assembly structure is improved.
Further, oil reservoirs 12 are provided on both end surfaces of the output gear 1, and oil passing holes 13 for communicating the two oil reservoirs 12 are provided. The structure of the oil storage tank 12 and the oil passing hole 13 facilitates the flow of lubricating oil, ensures the lubricating effect and avoids the abrasion of the tooth surface.
Further, a driving gear shaft 24 is provided on the hub 2 at an end thereof adjacent to the support shaft 22.
Further, the support shaft 22 is provided with a sealing ring groove 221. The sealing ring groove 221 facilitates the location of the sealing bearing.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
