For achieving the above object, the utility model provides a kind of hydraulic pump gear installation shaft, it is fixedly mounted on diesel engine gear chamber one side, and one end of installation shaft stretches in gear chamber, hydraulic pump gear is arranged on one end of installation shaft, it is characterized in that, in installation shaft internal entity part, is provided with grease channel, and grease channel extends to hydraulic pump gear installation position, grease channel and extraneous lubricating pipe are connected.
In technique scheme, at the other end of installation shaft, be provided with oil hydraulic pump mounting hole.
In technique scheme, installation shaft is mounted by means of bolts on gear chamber one side, and bolt hole is designed to blind hole in gear chamber.
In technique scheme, grease channel passed through oil draining bolt and extraneous lubricating pipe is connected.
In technique scheme, extraneous lubricating pipe and diesel lubrication oil system are connected.
Compared with prior art, the utlity model has following beneficial effect: by hydraulic pump gear installation shaft internal entity partial design lubricating oil duct, shorten and simplify the lubricated oil duct of getting of hydraulic pump gear, eliminate hydraulic pump gear and cause the fault of locking because of lack of lubrication; By redesign oil hydraulic pump mounting hole in hydraulic pump gear installation shaft, the design of staggering of the bolt hole of itself and hydraulic pump gear installation shaft and gear chamber, and then when oil hydraulic pump is installed, do not need to dismantle hydraulic pump gear installation shaft; By in gear chamber indoor design blind hole as hydraulic pump gear installation shaft retaining thread hole, avoid oil leakage phenomenon.
Accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
Hydraulic pump gear installation shaft of the present utility model is mainly the lack of lubrication that exists the oil leab complexity of hydraulic pump gear to cause in existing oil hydraulic pump installation process, overlapping the sharing of the mounting hole of hydraulic pump gear installation shaft and the mounting hole of oil hydraulic pump causes that the shortcoming of interactive problem and the leakage of oil of hydraulic pump gear installation shaft designs, correspondingly, the hydraulic pump gear installation shaft that the present embodiment provides is by changing existing lubricating oil duct, shorten and simplify the lubricated oil duct of getting of hydraulic pump gear, eliminate hydraulic pump gear and cause the fault of locking because of lack of lubrication; In hydraulic pump gear installation shaft, redesign oil hydraulic pump mounting hole, the design of staggering of the bolt hole of itself and hydraulic pump gear installation shaft and gear chamber, and then when oil hydraulic pump is installed, do not need to dismantle hydraulic pump gear installation shaft; When hydraulic pump gear installation shaft is fixed in gear chamber, its bolt hole is designed to blind hole in gear chamber inside, avoids oil leakage phenomenon.
As shown in Fig. 1 and Fig. 4, the hydraulic pump gear installation shaft 1 that the present embodiment provides, its one end is for installing hydraulic pump gear portion (unmarked in figure), the other end is flange part (unmarked in figure), hydraulic pump gear installation shaft 1 is fixedly mounted on diesel engine gear chamber (unmarked in a Fig. 1) side by flange part, the installation hydraulic pump gear portion of hydraulic pump gear installation shaft 1 stretches in gear chamber, in gear chamber, hydraulic pump gear is arranged on one end (referring to Fig. 3) of hydraulic pump gear installation shaft 1, and press pump gear drives oil hydraulic pump 10 to work by hydraulic pump driving axle 30.In the present embodiment, the installation position of hydraulic pump gear and hydraulic pump gear installation shaft 1 need to be lubricated, it is real like this, in installation shaft 1 internal entity part, be provided with grease channel 11, and grease channel 11 extends to hydraulic pump gear installation position, grease channel 11 is connected with extraneous lubricating pipe 40, the lubricant oil extraneous lubricating pipe 40 of process and grease channel 11 enter hydraulic pump gear installation position it are lubricated, shorten greatly and simplify the lubricated oil duct of getting of hydraulic pump gear, guarantee enough lubricating.
Why the present embodiment redesigns the mounting hole of oil hydraulic pump 1 in hydraulic pump gear installation shaft 1, to consider that oil hydraulic pump 10 is generally to install when final assembly, before oil hydraulic pump 10 is installed, hydraulic pump gear installation shaft 1 generally all installs in gear chamber, overlapping the sharing of mounting hole of the mounting hole of existing hydraulic pump gear installation shaft 1 and oil hydraulic pump 10, when dismounting oil hydraulic pump 10, can bring infringement to hydraulic pump gear installation shaft 1, so, in the hydraulic pump gear installation shaft 1 that the present embodiment provides, redesign the mounting hole 13(of oil hydraulic pump 1 referring to Fig. 2), correspondingly, designed in addition cover plate 70, before oil hydraulic pump 10 is installed, utilize cover plate 70 to seal the installation position of oil hydraulic pump 10.
