The integrated power takeoff comprises a power takeoff shell, a transmission gear, a driving gear, an output shaft, an output bearing and a rear bearing cover, wherein the transmission gear is arranged in the power takeoff shell and meshed with an intermediate gear of an external transmission; the rear bearing cover and the power takeoff shell are integrally processed and formed. The output part of this integrated form power takeoff has reduced the assembly part of power takeoff assembly, practices thrift the cost, and simple structure is convenient for produce, avoids the risk of combining the face oil leak, and the scene is reformed transform easily.
Description
Technical Field
The utility model relates to a power takeoff, concretely relates to integrated form power takeoff.
Background
The traditional power takeoff output structure provides spline power takeoff and flange power takeoff, wherein the spline power takeoff mode needs to be installed on power takeoff casing 01 and can be used after parts such as rear bearing cap 02, gasket and bolt of output shaft, as shown in fig. 1, rear bearing cap 02 and power takeoff casing 01 of output shaft are fixed through bolted connection, and adopt the gasket to seal on power takeoff casing 01 and the rear bearing cap 02 contact end face of output shaft, the assembly parts are more, the cost is high, and the risk of oil leakage still exists between the rear bearing cap 02 and the power takeoff casing 01 junction surface. When the flange plate output structure (flange plate power take-off) needs to be modified into the spline output structure (spline power take-off) on site, various parts need to be replaced, and the modification on site is difficult.
Disclosure of Invention
The utility model aims at solving the spline power takeoff mode assembly part of current power takeoff output structure more, it is with high costs, have oil leak risk and the difficult technical problem of scene transformation, provide an integrated form power takeoff.
In order to solve the technical problem, the utility model provides a technical solution as follows:
an integrated power takeoff is characterized in that: the transmission gear is arranged in the power takeoff shell and meshed with an intermediate gear of an external transmission, a driving gear coaxially arranged with the driving gear, an output gear meshed with the driving gear, an output shaft in interference fit with an inner ring of the output gear, an output bearing arranged at a shaft shoulder on the right side of the output shaft, and a rear bearing cover arranged on the right side of the output bearing; the rear bearing cover and the power takeoff shell are integrally processed and formed; the output shaft extends out of the rear bearing cover.
Further, the output shaft extends out of the rear bearing cover part to form a spline structure.
Furthermore, an elastic retainer ring is arranged between the output bearing and the rear bearing cover.
The utility model discloses compare the beneficial effect that prior art has:
1. the utility model provides an integrated form power takeoff output structure, it is integrated with the power takeoff casing with the back bearing cap of output shaft, from the power takeoff output structure of taking the back bearing cap interface. The output part of the integrated power takeoff reduces the assembly parts of the power takeoff assembly, saves cost, has a simple structure, is convenient to produce, saves the assembly of a liner and a rear bearing cover of an output shaft in the assembly process, and is convenient to install; the risk of oil leakage at the joint surface of the rear bearing cover and the power takeoff shell is avoided;
2. the utility model provides an integrated form power takeoff output structure switches the in-process at ring flange output structure and spline output structure, only need install additional or dismantle the ring flange can, greatly made things convenient for the on-the-spot transformation of ring flange power take-off and spline power take-off output structure.

Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, the integrated power takeoff of the present invention includes a power takeoff housing 1, a transmission gear 2 disposed inside the power takeoff housing 1 and engaged with an intermediate gear of an external transmission, a driving gear 3 disposed coaxially with the transmission gear 2, an output gear 4 engaged with the driving gear 3, an output shaft 5 in interference fit with an inner ring of the output gear 4, an output bearing 6 disposed at a right shoulder of the output shaft 5, and a rear bearing cover 7 disposed at a right side of the output bearing 6; the rear bearing cover 7 and the power takeoff housing 1 are integrally processed and formed; the output shaft 5 extends out of the rear bearing cover 7, and the extending part is of a spline structure. And an elastic retainer ring 8 is arranged between the output bearing 6 and the rear bearing cover 7.
The utility model discloses with the rear bearing cap 7 of output shaft 5 and power takeoff casing 1 integration, from the power takeoff output structure of taking the 7 interfaces of rear bearing cap. The integrated rear power takeoff output structure can effectively reduce power takeoff assembly assembling parts, saves cost, and can avoid the risk of oil leakage of the joint surface of the rear bearing cover 7 and the power takeoff shell 1. The assembly of the gasket and the output shaft rear bearing cap 7 is omitted in the assembly process. In the process of switching the flange and the spline output structure, only the flange plate needs to be additionally installed or detached.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for a person skilled in the art to modify the specific technical solutions described in the foregoing embodiments or to equally replace some technical features of the embodiments, and these modifications or replacements do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions protected by the present invention.
