Fixed pin 7 '.By float grease seal 5 ' and sealing ring 4 ', the space of a sealing is formed between wheel body 1 ' and wheel shaft 2 ', it should
Lubricating oil is stored in the space of sealing, lubricating action is played in the relative rotation between wheel body 1 ' and wheel shaft 2 '.
Since lubricating oil is the loss product of engineering machinery, often through after a period of time with regard to being replaced, therefore it is above-mentioned close
The space of envelope needs that oil filler point is arranged.Conventionally, oil filler point 8 ' is opened in the medium position of wheel body 1 ', and shape is cylinder,
Usually plug 9 ' is used to seal oil filler point 8 ', plug 9 ' is removed when needing replacing lubricating oil.Thrust wheel is in operational process
In, stress is non-uniform, concentrates on bottom.The starting stage of thrust wheel, bottom friction calorific value is big, however, due to stress
The oil film squeezed herein is very thin, causes fever to be not easy to conduct in time, saves bit by bit on metalwork so that metalwork is easily deformed mill
Damage.
Utility model content
Technical problem to be solved in the utility model is to improve the mobility of lubricating oil in thrust wheel so that on metalwork
Heat can be in time by heat loss through conduction.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of thrust wheel, including：Wheel shaft passes through
Axle sleeve is rotatably arranged on the wheel body on wheel shaft, positioned at wheel body both sides and is fixed on the end cap on wheel shaft, be located at end cap and wheel shaft it
Between sealing ring, the float grease seal between end cap and wheel body, be located at end cap separate wheel body side fixed pin, the wheel
Lubricating oil storage space is formed in the middle part of the madial wall of body between wheel shaft, the middle part of the wheel body is formed to be stored to the lubricating oil
The protruding portion extended in space.
Further, the protruding portion is the strip extended along the axial direction of wheel body.
Further, the both ends of the protruding portion are connect with the madial wall of the wheel body.
Further, the protruding portion is one.
Further, the protruding portion is positioned opposite two.
Further, the protruding portion is wholely set with wheel body.
By adopting the above-described technical solution, the utility model has the following advantages：Protruding portion can turn with wheel body
It moves and rotates, stirring is formed to the lubricating oil in lubricating oil storage space, promotes lubricating oil constantly to circulate so that metalwork
On heat can reduce the formation abrasion of metalwork in time by heat loss through conduction.

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, the oil filler point 8 are connected to the lubricating oil storage space.The middle part of the wheel body 1 is formed to be stored to the lubricating oil
The protruding portion 10 extended in space.
Above-mentioned protruding portion 10 is rotated with the rotation of wheel body 1, and stirring is formed to the lubricating oil in lubricating oil storage space.
When protruding portion 10 and lubricating oil contact, the power pushed to 3 direction of axle sleeve is formed to lubricating oil, lubricating oil is promoted to flow to axle sleeve 3.
When the lubricating oil liquid level between axle sleeve 3 and float grease seal 5 increases, lubricating oil can flow back to the lubricating oil storage space again.Therefore,
Lubricating oil is promoted constantly to circulate so that the heat on metalwork can reduce the change of metalwork in time by heat loss through conduction
Shape is worn.
As than more preferably scheme, the protruding portion 10 is the strip extended along 1 axial direction of wheel body.And it is prominent
The both ends in portion 10 are connect with the madial wall of the wheel body 1.
A protruding portion 10 is only provided in Fig. 2, and in other embodiments, it is prominent that positioned opposite two can be set
Go out portion 10, thus the stress on wheel body 1 is more balanced.The quantity of protruding portion 10 is advisable with two, if quantity is excessive, instead can
The reflux for influencing lubricating oil is unfavorable for reinforcing cycle.
The protruding portion 10 is wholely set with wheel body 1, machines simultaneously, need not increase additional work in processing
Sequence, therefore increasing substantially for cost will not be caused.
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.
