As preferred：The diameter of the carrier one is identical with the diameter of the carrier two.
As preferred：The diameter of the carrier one is less than the diameter of wheel body construction section.
As preferred：The oil groove one, oil groove two, oil groove three and oil groove four it is of same size.
As preferred：The upper center of the carrier two is provided with dowel hole.
As preferred：The area on the left of fluting in the plane one is more than the area on fluting right side.
As shown from the above technical solution, the advantageous effect of this practicality is：
1, the setting of the shaft shoulder and oil storage tank, the shaft shoulder are that do not have big axial float when thrust wheel being made to work, and then make Zhi Chong
The phenomenon that taking turns oil leak at work is eased, and when the shaft shoulder and wheel body set are used cooperatively, needs lubricating oil to slow down abrasion
Lubrication have additional oil storage tank in order to avoid the quick consumption of shaft shoulder position lubricating oil, the setting of oil storage tank is that the shaft shoulder is made to reach
Certain oil storage effect increases the amount of shaft shoulder position lubricating oil, and what can be used is more long, reduces abrasion to a certain extent, increases
Add service life, also avoids the trouble for adding lubricating oil always.2, the setting of plane one, plane two and fluting, with traditional circle
Shape end cap construction section is compared, since the setting of plane one, plane two and fluting can play the effect of certain positioning anti-rotation, with
What is connected between end cap is even closer.3, the setting of oil groove one, oil groove two, oil groove three and oil groove four is to increase left end
The oil reserve of lid construction section, right end cap construction section, carrier one and carrier two, when increasing primary plus lubricating oil use
Between, the abrasion condition between fulcrum and each component is reduced, the service life of fulcrum is extended.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the fulcrum of bull-dozer thrust wheel of the utility model.
Specific implementation mode
A kind of fulcrum of bull-dozer thrust wheel of the utility model is described further referring to Fig.1.
A kind of fulcrum of bull-dozer thrust wheel, it is characterised in that：Including branch shaft body, the branch shaft body includes wheel body peace
Dress section 1 and end cap construction section, the centre of the branch shaft body are provided with the shaft shoulder 2, and the outer middle side part of the shaft shoulder 2 is surrounded with oil storage
Slot 3, the end cap construction section include left end cap construction section 4 and right end cap construction section 5, and the left end cap construction section 4 is located at wheel body
The left side of construction section 1, the right end cap construction section 5 are located at the right side of wheel body construction section 1, the left end cap construction section 4 with it is described
