Abstract
The invention discloses an engineering machine track support part which comprises wheel bodies. A shouldered shaft sleeve and a non-shouldered shaft sleeve are sleeved into one ends of the wheel bodies sequentially, a shaft sequentially penetrates through the shouldered shaft sleeve and the non-shouldered shaft sleeve to be arranged inside the wheel bodies, a floating seal seat sleeve is fixed with the wheel bodies through floating ring assemblies and one the other side of the non-shouldered shaft sleeve on the shaft. A floating seal seat is provided with a floating seal seat pin hole, the shaft is provided with a shaft pin hole, an O-ring is arranged at the contact position of the floating seal seat and the shaft, and a side cover is fixedly arranged outside one side, provided with the shouldered shaft sleeve, of the shaft. The support part internally adopts floating seal, thereby being good in sealing effect. A floating ring has an automatic compensation function after being worn in use, and the inside of each wheel body adopts an integral shaft so that severe wear of the shaft sleeves due to the fact that axial plane is not perpendicular to the end face of a gasket is avoided.
Description
Technical field
The present invention relates to a kind of support component, relate in particular to the support component that a kind of engineering is used crawler belt.
Background technology
Crawler belt be by driving wheel drive, round the flexible chain link of driving wheel, bearing wheed, inducer and carrier wheel.Crawler belt is comprised of caterpillar block and track pin etc.Track pin couples together the formation track link with each caterpillar block.The two ends of caterpillar block are porose, and with the driving wheel engagement, tooth is induced at the middle part, is used for advising positive crawler belt, in the one side that contacts with ground the anti-skidding muscle (abbreviation decorative pattern) of reinforcement is arranged, with the impregnability of raising caterpillar block and the adhesive ability on crawler belt and ground.Support component is used for auxiliary caterpillar drive, tool important role.Existing crawler belt support component is because wearing and tearing are severe, and specification is single, can not adapt to the demand of different size crawler belt.
Because the defective that above-mentioned existing support component exists, the design people, actively research and innovation in addition in the hope of founding a kind of support component of new structure, makes it have more practicality.
Summary of the invention
Main purpose of the present invention is, overcome the defective that existing support component exists, and provide a kind of support component of new structure, technical matters to be solved be simple in structure, easy processing, easy for installation, can prevent derailing, all can support the use with steel crawler belt and rubber belt track, thereby more be suitable for practicality, and have the value on the industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of construction machinery and equipment crawler belt support component according to the present invention's proposition, comprise wheel body, described wheel body one end has been inserted in first the shoulder axle sleeve, be inserted in without the shoulder axle sleeve, axle has passed successively the shoulder axle sleeve and has been arranged on wheel body inside without the shoulder axle sleeve, floating sealing base is enclosed within nothing shoulder axle sleeve opposite side on the axle, fixes by floating ring assembly and described wheel body.
Aforesaid construction machinery and equipment crawler belt support component, described floating sealing base is provided with the floating sealing base pin-and-hole.
Aforesaid construction machinery and equipment crawler belt support component, described axle is provided with pin hole.
Aforesaid construction machinery and equipment crawler belt support component, the contacted position of described floating sealing base and axle is provided with O type circle.
Aforesaid construction machinery and equipment crawler belt support component, described axle are provided with the one side external stability of shoulder axle sleeve and are provided with side cover.
By technique scheme, construction machinery and equipment crawler belt support component of the present invention has following advantages at least:
The inner floating seal that adopts of support component of the present invention after good sealing effect, floating ring in use wear and tear, has automatic compensation function.The inner integral shaft that adopts of wheel body is avoided axis plane and pad end face out of plumb so that the axle sleeve serious wear.
In sum, the construction machinery and equipment crawler belt support component of special construction of the present invention, it has above-mentioned many advantages and practical value, thereby more is suitable for practicality.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification sheets, below with preferred embodiment of the present invention and cooperate accompanying drawing to be described in detail as follows.
Description of drawings
The structural representation of Fig. 1 construction machinery and equipment crawler belt of the present invention support component.
The specific embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment of the present invention is described in detail as follows.
As shown in Figure 1, construction machinery and equipment crawler belt support component of the present invention comprises wheel body 1, axle 2, side cover 3, floating sealing base 4, bearing pin 5, without shoulder axle sleeve 8, shoulder axle sleeve 7 is arranged, floating ring assembly 6, after 1 welding of 9. two wheel bodys of O type circle, eliminate stress, there is shoulder axle sleeve 7 to be pressed into wheel body 1 without float grease seal end endoporus, be pressed into wheel body 1 without shoulder axle sleeve 8 float grease seal end endoporus is arranged, two floating ring assemblies 6 are respectively charged between wheel body 1 and the floating sealing base 4, with axle 2 one ends from have the shoulder axle sleeve 7 pass through, through nothing shoulder axle sleeve 8, put O type circle 9, floating sealing base 4 axle of packing into makes the control of floating sealing base pin and pivot pin control alignment, load onto pivot pin 5, load onto side cover 3 and be screwed.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
