Embodiment 2
Please refer to Fig. 4~5, in the embodiment of the present invention, a kind of machine driven system, since in practical applications, top box is defeated
Shaft D1 is right angle setting, and top box output flange E1 and the junction top box output shaft D1 are chronically at swing (dynamic balancing is bad)
Rotation status, this allows for the originally top box output shaft oil sealing of long period of soaking in the oil, due to clast, greasy filth heap always in top box
Product is in the contact position of oil seal lip and top box output shaft D1, and prolonged relative rotation necessarily causes the breakage of oil seal lip, most
Lead to leakage of oil herein eventually, cannot such as find in time, will lead in top box and output and input gear overheat, bearing, oil sealing, tooth
The ablations such as wheel, which are even failed, beats tooth.
Based on this, present embodiment discloses flow deflector F1, the flow deflector F1 is mounted on top box output gear C1 and top box
Between bearing between output shaft D1 and upper tank shell B1, flow deflector F1 thickness 0.8mm or so, diameter of bore is slightly larger than in bearing
Bore dia (avoids directly contacting with top box output shaft D1), and outside diameter is smaller than the upper tank shell B1 internal diameter in horizontal direction
6mm or so.Lubricating oil in tank shell B1 upper in this way can (circumferencial direction be by the gap of flow deflector F1 and upper tank shell B1
3mm or so) flow direction lower section, lubrication bearing, oil sealing etc., and can make clast, greasy filth etc. can only be by flow deflector F1 and upper tank shell
The gap (3mm or so) of B1 axial direction flows downward to enter and is assembled to form by outer race, bearing gland, upper tank shell B1 three
Deposition in spare slot can hold the greasy filth, clast that top box generates in 3~5 years completely, keep away since the volume of spare slot is sufficiently large
Exempted from greasy filth, clast directly flows to oil seal lip through bearing clearances, while protecting bearing, greatly improve the work of oil sealing
Make environment, solves the problems, such as that oil sealing abnormal damage causes leakage of oil.
Embodiment 3
In the embodiment of the present invention, a kind of wheel excavator comprising the machine driven system as described in above-described embodiment, because
And it also has the advantages that low or first gear large speed ratio, ratio coverage be wide and high reliability, while also good with top box not easy oil leakage
Place.
It should be strongly noted that in the technical program, using third gear main tank, the composition knot of two grades of odd-sides and one grade of top box
Structure is successfully realized six-gear gearbox ratio coverage covering 1.0~8.5, has fully met the use demand of wheel excavator,
It is improved in terms of properity compared with original product, shown in table 1 specific as follows；Meanwhile the design of flow deflector, protecting bearing
While, the working environment of oil sealing is greatly improved, solves the problems, such as that oil sealing abnormal damage causes leakage of oil.
