Abstract
The present invention proposes a kind of packing ring for machinery chassis, washer body including cirque structure, it is smooth flat above washer body, washer body is issued provided with a circle dashpot, some through holes, through hole connection washer body top and dashpot, good airproof performance are also uniformly provided with packing ring, service life is improved, more securely and reliably.
Description
Technical field
The present invention relates to a kind of packing ring, and in particular to a kind of packing ring for machinery chassis.
Background technology
At present, engineering machinery chassis, particularly caterpillar engineering machinery chassis, its structure type is typically by being placed in centre
It is used to arrange that the longeron three parts of running gear to form for connecting the H framves got on the bus and splitting the left and right sides.Machinery chassis is in group
Need to use packing ring during dress, existing packing ring fatigue resistance is bad, and service life is shorter, fragile, influences machinery chassis
Normal use.
The content of the invention
The present invention proposes a kind of packing ring for machinery chassis regarding to the issue above, good airproof performance, improves using the longevity
Life, more securely and reliably.
Specific technical scheme is as follows：
A kind of packing ring for machinery chassis, include the washer body of cirque structure, be smooth flat above washer body, pad
Circle main body issues encloses dashpot provided with one, and some through holes, through hole connection washer body top and buffering are also uniformly provided with packing ring
Groove.
Further, the dashpot caves inward, its section is in isosceles trapezoidal structure.
Further, the quantity of the through hole is 4-6.
Further, the cross sectional shape of the through hole is up big and down small isosceles trapezoidal structure.
Further, 2 times of its a diameter of lower surface diameter of the upper surface of the through hole.
Beneficial effects of the present invention are：Good airproof performance of the present invention, service life is improved, more securely and reliably.
Brief description of the drawings
Fig. 1 is sectional view of the present invention.
Embodiment
To make technical scheme become apparent from clearly, below the present invention is described further, it is any to this
The scheme that the technical characteristic progress equivalencing of inventive technique scheme and conventional reasoning are drawn each falls within the scope of the present invention.
A kind of packing ring for machinery chassis, include the washer body 1 of cirque structure, put down above washer body to be smooth
Face, washer body issues encloses dashpot 2 provided with one, and some through holes 3, through hole connection washer body top are also uniformly provided with packing ring
And dashpot.
Further, the dashpot caves inward, its section is in isosceles trapezoidal structure.
Further, the quantity of the through hole is 4-6.
Further, the cross sectional shape of the through hole is up big and down small isosceles trapezoidal structure.
Further, 2 times of its a diameter of lower surface diameter of the upper surface of the through hole.
