Description
Technical field
The utility model is related to a kind of power transmission shaft, and in particular to a kind of helical teeth power transmission shaft.
Background technology
In the prior art, axial plunger duplex pump, is driven using straight-tooth gear more, in high-speed cruising, due to manufacture
And alignment error, the unexpected tooth of gear enters to go out with unexpected tooth, forms impact, and not only noise is big, and easily produces vibrations.
The content of the invention
Goal of the invention：The purpose of this utility model is to overcome deficiency of the prior art, there is provided one kind operates steadily,
Gearratio is constant, and noise is small, is more suitable for the axial plunger duplex pump helical teeth power transmission shaft of high-speed cruising.
Technical scheme：In order to solve the above-mentioned technical problem, axial plunger duplex pump described in the utility model is passed with helical teeth
Moving axis, it includes transmission shaft body, and the transmission shaft body includes input section, oil sealing section, big bearing section, transmission segment and small bearing
Section and linkage section, rolling bearing is provided with the big bearing section, and helical gear, the helical gear are provided with the rolling bearing
External diameter be with the external diameter ratio of rolling bearing（2-2.6）：1.
The input section, oil sealing section, big bearing section, transmission segment and small bearing section and linkage section are integrally formed.
The helical gear external diameter is 2.5 with the external diameter ratio of rolling bearing：1.
Beneficial effect：Compared with prior art, its remarkable advantage is the utility model：The utility model structure setting is closed
Reason, spur gear is replaced using helical gear, and external diameter ratio is set be（2-2.6）：1 helical gear and rolling bearing, makes overall fortune
Row is steady reliable, and the unexpected tooth of spur gear enters the vibrations and impact for going out with unexpected tooth and bringing before solving, and gearratio is constant, noise
Small, this structure is more suitable for high-speed cruising, meets actual operation requirements.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in figure 1, axial plunger duplex pump helical teeth power transmission shaft described in the utility model, it includes power transmission shaft sheet
Body, the transmission shaft body includes input section 1, oil sealing section 2, big bearing section 3, transmission segment 4 and small bearing section 5 and linkage section 6,
The big bearing section 3 is provided with rolling bearing 7, is provided with helical gear 8 on the rolling bearing 7, the external diameter of the helical gear 8 with
The external diameter ratio of rolling bearing 7 is（2-2.6）：1；The input section 1, oil sealing section 2, big bearing section 3, transmission segment 4 and small bearing section 5
It is integrally formed with linkage section 6.The utility model structure setting rationally, replaces spur gear, and set external diameter ratio using helical gear
For（2-2.6）：1 helical gear and rolling bearing, makes overall operation steadily reliable, and the unexpected tooth of spur gear enters and dashes forward before solving
Right tooth goes out the vibrations and impact for bringing, and gearratio is constant, and noise is small, and this structure is more suitable for high-speed cruising, meets actually used wanting
Ask.
The utility model provides a kind of thinking and method, and the method and approach for implementing the technical scheme are a lot, with
Only it is preferred embodiment of the present utility model described in upper, it is noted that for those skilled in the art,
On the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications should also be regarded
It is protection domain of the present utility model, each part being not known in the present embodiment can use prior art to be realized.
