Description
Technical field
The utility model is related to a kind of lubrication systems being installed on output shaft of gear-box gear, belong to gearbox equipment skill
Art field.
Background technology
Gearbox is one of important transmission parts of loading machine, and the speed and torque that it is responsible for transmitting in engine pass to
Final drive system.Gearbox as shown in Figure 1, in practical work process, due to the output shaft of gear-box tooth of drive connection
There is no the lubrication of fluid, therefore cause the working life of gearbox shorter between the axis spline of internal spline and the working gear pump of wheel
（Through calculating at 3500-5500 hours or so）.After gearbox reaches working life, it is necessary to integral replacing output shaft of gear-box
Gear is pumped with working gear, so as to increase use and maintenance cost.
Utility model content
For above deficiency, the purpose of this utility model is to provide a kind of lubrication being installed on output shaft of gear-box gear
That is, on the basis of original structure shape is not changed, output shaft of gear-box gear and work are realized by adding oil duct for structure
The lubrication of gear pump shaft spline, and then increase the service life of gearbox, reduce the maintenance cost of gearbox.
The utility model is implemented by the following technical programs：The lubrication knot being installed on output shaft of gear-box gear
Structure, structure are：At output shaft of gear-box gear and working gear pump connecting portion A, the internal spline of output shaft of gear-box gear
It is connect with the axis spline drived of working gear pump, wherein being extended radially through on the internal spline of output shaft of gear-box gear equipped with extremely
A few oil duct through-hole.
Preferably, oil duct through-hole is connect through oil leab with external pressure oil fueller.
Preferably, the oil duct through-hole is pairs of and arranged symmetrically, which so that lubricant effect is more satisfactory.
Preferably, restriction is equipped at one on oil leab, the setting of restriction is so that at this on oil leab
Bore is smaller, on the one hand can not only increase the lubrication pressure of oil duct, on the other hand can reduce the flow of lubricating oil, and then keep away
Exempt to influence the work at other positions due to oil mass is excessive.
Preferably, the end of oil leab is equipped with spare interface, and external pressure oil fueller is through spare interface and profit
Grease way connect, outer portion's fueller can be the fueller or gearbox specially set manipulation valve or
Other pressure positions.
Preferably, oil sealing is installed additional at output shaft of gear-box gear and working gear pump connecting portion A, in order to avoid extra speed change
Case oil enters hydraulic oil container by working gear pump, in turn results in unnecessary repair.
The technique effect of the utility model：The utility model on the internal spline of output shaft of gear-box gear by adding profit
Grease way to reach lubricant effect, can be exported using the axial leakage oil of speed-variable pump operation to lubricate in gearbox
Shaft gear is pumped with working gear at connecting portion A, and the oil after lubrication returns to gear box oil bottom through gear-box axle gear rear end, can also
Using spare interface and oil leab forced feed lubrication, quote external pressure oil fueller, as the manipulation valve of gearbox or its
His pressure position；It is further preferred to install oil sealing additional at output shaft of gear-box gear and working gear pump connecting portion A, so as not to it is extra
Gear box oil by working gear pump enter hydraulic oil container, in turn result in unnecessary repair；It, can using the utility model
The apparent service life for increasing gearbox, reduces maintenance cost, extends the gearbox repairing period.
