Specific implementation mode
For the ease of understanding the above objects, features, and advantages of the utility model, it is illustrated with reference to embodiment.It answers
Understand, these embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model.For these implementations
A variety of modifications of example will be apparent to those skilled in the art, the general principles defined herein,
It can be achieved in other embodiments without departing from the spirit or scope of the present utility model.
A kind of thrust wheel shown in Figure 2, including：Wheel shaft 2 is rotatably arranged on the wheel body 1 on wheel shaft 2 by axle sleeve 3,
Positioned at 1 both sides of wheel body and the end cap 6 that is fixed on wheel shaft 2, the sealing ring 4 between end cap 6 and wheel shaft 2, be located at end cap 6 with
Float grease seal 5 between wheel body 1 is located at the fixed pin 7 of 1 side of separate wheel body of end cap 6, the note being opened on the wheel body 1
Oilhole 8, and the plug 9 in oil filler point 8.Lubricating oil storage is formed in the middle part of the madial wall of the wheel body 1 between wheel shaft 2
Space A, the oil filler point 8 are connected to the lubricating oil storage space A.The float grease seal 5, wheel body 1, wheel shaft 2 and end cap 6 it
Between formed gap B.The lubrication oil circulation pipe for being connected to the lubricating oil storage space A with the gap B is formed on the wheel body 1
Road 10.
Lubricating oil storage space A can be connected to by the lubrication oil circulation pipeline 10 with gap B, therefore, with wheel body 1
Rotation, lubricating oil can circulate between lubricating oil storage space A and gap B.Rationally design the side of lubrication oil circulation pipeline 10
To can more advantageously push the mobility of lubricating oil between.For example, the extension side of the lubrication oil circulation pipeline 10
To, first opening that is located at lubricating oil storage space A at of the lubrication oil circulation pipeline 10 not parallel with the axial line of wheel shaft 2
With the second opening being located at the B of gap and 2 axle center of wheel shaft for being more than the lubrication oil circulation pipeline 10 at a distance from 2 axial line of wheel shaft
The distance of line.Thus, when lubrication oil circulation pipeline 10 is rotated from lower position to higher position, lubricating oil will be from the second opening
Outflow, namely flows within the B of gap, and oil pressure in the B of gap will so be caused to increase so that lubricating oil again from wheel shaft 2 and axle sleeve 3 it
Between gap or axle sleeve 3 and wheel body 1 between gap flow to lubricating oil storage space A.And when lubrication oil circulation pipeline 10 by
When higher position is rotated to lower position, lubricating oil is filled again to the lubrication oil circulation pipeline 10, so on circulate.
Angle between the extending direction and the axial line of wheel shaft 2 of the lubrication oil circulation pipeline 10 is in the conceived case
Higher value should be chosen, is greater than 10 °, bigger pressure can be so caused to gap B, has facilitation to lubrication oil circulation.
Lubrication oil circulation pipeline 10 between the lubricating oil storage space A and each gap B is preferred with being arranged one, with
It avoiding when oil pressure increases in the B of gap, lubricating oil is flowed out from the lubrication oil circulation pipeline 10 of lower, rather than from wheel shaft 2 and axis
Gap outflow between gap or axle sleeve 3 and wheel body 1 between set 3.
In fig. 2, the diameter of the lubrication oil circulation pipeline 10 is constant, however, it is also possible to using the lubrication of reducing
Oil circuit piping 10 is open to the direction of the second opening along from first referring to Fig. 3, the lubrication oil circulation pipeline 10 it is straight
Diameter successively decreases.So there are two design at least tools the advantages of aspect：First, when filling lubricating oil into lubrication oil circulation pipeline 10,
It avoids generating and is bubbled and loading is caused to reduce；Second, more lubrication oil volumes can be stored.In figure 3, lubrication oil circulation
The diameter of pipeline 10 is gradual change, under some embodiments, can also use hierarchic structure etc..
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations.
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It can still modify to the technical solution recorded in previous embodiment, either to which part or all technical features
Progress equivalent replacement, and these modifications or substitutions, various embodiments of the utility model that it does not separate the essence of the corresponding technical solution
The range of technical solution.
