Description
Technical field
It the utility model is related to engineering machinery accessories field, and in particular to a kind of thrust wheel.
Background technology
Thrust wheel is the one kind of four-wheel one with the crawler bodies such as excavator, bull-dozer, its main function is support
The weight of excavator, bull-dozer, allows crawler belt to advance along wheel, is normally between running part bottom and caterpillar chain, during operation
Rolling friction is formed, so that frictional resistance when reducing equipment walking.
Authorized announcement date is to disclose a kind of excavation in the Chinese patent CN203992846U documents on December 10th, 2014
The friction welding (FW) divided edge structure of machine thrust wheel wheel body, including revolver body, right wheel body, two wheel bodys be respectively equipped with the first pressure contact portion and
Second pressure contact portion, first pressure contact portion of the revolver body and second pressure contact portion of the right wheel body are by being welded to connect
Together.Wherein, it is by the way of crimping that revolver body and right wheel body is affixed in one, but this mode is produced on the inside of electrolysis
Raw extruding projection, it is impossible to it is completely enclosed, it is not completely enclosed easily to be caused to taking turns internal working oil between the two there are certain interval
Pollution, and since the contact area of electrolysis is small, whole thrust wheel can bearing strength it is not high, do not possess good service life.
Utility model content
Therefore, in view of the above-mentioned problems, the utility model provides the thrust wheel that a kind of force-applied intensity is big, lasts a long time.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions：
A kind of thrust wheel, including thrust wheel body, wheel shaft and float grease seal, the thrust wheel body are installed on described by axle sleeve
On wheel shaft, working oil chamber is formed between wheel shaft and the thrust wheel body, the thrust wheel body both sides are respectively equipped with end cap, described floating
Dynamic oil sealing is installed between thrust wheel body and end cap, and the thrust wheel body includes revolver body, right wheel body and for both affixed
The circumferential outer surface that both the weld part of end, the revolver body and right wheel body are connected one end end is equipped with and centroclinal inclines
Inclined portion, the weld part are embedded in the end face that the revolver body is connected with right wheel body.
Preferably, the joint face of the revolver body and right wheel body is cascaded surface.
Preferably, the end of the right wheel body is embedded in the end of the revolver body, the company of the revolver body and right wheel body
Junction is equipped with the flange and groove of both clampings.
Preferably, the flange coordinates with groove for transition.
Preferably, the end cap props up formation oil sealing chamber between sleeve end and thrust wheel body, the float grease seal installation
In the oil sealing intracavitary, the oil sealing intracavitary positioned at the thrust wheel body, axle sleeve, end cap three connection is provided with sealing ring.
By using preceding solution, the beneficial effects of the utility model are：The utility model is using revolver body and the right side
The form of wheel body outside weldings, has abandoned the form of friction welding (FW), sets the revolver body and right wheel body being mutually clamped, connects both
Place is completely enclosed, increases bonding area, strengthens the bearing capacity of thrust wheel, ensure that the good leakproofness of working oil chamber, at the same time
The oil enveloping structure of end cap and thrust wheel body is improved, ensure that sealing effect, the stability of mounting structure is improved, improves
The intensity and service life of thrust wheel.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model embodiment；
Fig. 2 is partial enlarged view at A in Fig. 1；
Fig. 3 is partial enlarged view at B in Fig. 1.
Embodiment
Describe the embodiment of the utility model in detail below with reference to specific embodiment, whereby to the utility model such as
What application technology means solves technical problem, and that reaches technique effect realizes that process can fully understand and implement according to this.
Embodiment
With reference to figure 1 and Fig. 2, a kind of thrust wheel, including thrust wheel body 1, wheel shaft 2 and float grease seal 3, the thrust wheel body 1
It is installed on by axle sleeve 21 on the wheel shaft 2, working oil chamber 4, the thrust wheel is formed between the wheel shaft 2 and thrust wheel body 1
