Abstract
The utility model relates to a road roller part especially relates to the steering cylinder of road roller, and it includes cylinder and piston, and the piston is installed in the cylinder, and the piston has a recess of installation sealing washer a week, has a sealing washer at the position that piston and cylinder contacted, the degree of depth of recess be 1.5-1.8 times of width, every recess in install the twice sealing washer, the cross -section of twice sealing washer all be the circular shape structure, such road roller steering cylinder has that sealing performance is better, difficult to be taken place to leak and the outer advantage of leaking, guaranteeing normal use.
Description
Technical field
The utility model relates to road roller parts, particularly relates to the steering cylinder of road roller.
Background technique
Steering cylinder is the vitals of road roller hydraulic system; it comprises cylinder barrel and piston; piston is arranged in cylinder barrel; the position contacted with cylinder barrel at piston has seal ring; such steering cylinder is let out in usually occurring, leak outside phenomenon, and it not only wastes hydraulic oil, and reduces the active force of oil cylinder; time serious, road roller can not travel, and even can bring other fault.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of sealability better, not easily to occur to leak and leak outside, ensure the normal steering cylinder of roller used.
The technical solution of the utility model is achieved in that steering cylinder of roller, comprise cylinder barrel and piston, piston is arranged in cylinder barrel, piston has installs the seal ring groove of a week, the position contacted with cylinder barrel at piston has seal ring, it is characterized in that: the degree of depth of described groove is 1.5 ~ 1.8 times of width, in described each groove, two seals circle is installed.
Say further, the cross section of described two seals circle is all circular structure.
The beneficial effects of the utility model are: such steering cylinder of roller has sealability and better, not easily occurs to leak and leak outside, ensure the normal advantage used, and the cross section of described two seals circle is all circular structure, has the advantage of better effects if.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model steering cylinder of roller.
Wherein: 1, cylinder barrel 2, piston 3, seal ring 4, groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1: steering cylinder of roller, comprise cylinder barrel 1 and piston 2, piston 2 is arranged in cylinder barrel 1, piston 2 has installs the seal ring groove of 3 one weeks 4, the position contacted with cylinder barrel at piston has seal ring, it is characterized in that: the degree of depth of described groove is 1.5 ~ 1.8 times of width, in described each groove 4, two seals circle 3 is installed.Have the darker degree of depth like this, guarantee can install two seals circle, simultaneously can not be too dark, ensures that seal ring contacts with the wall of cylinder barrel, has sealing effect like this.
Say further, the cross section of described two seals circle is all circular structure.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
