Abstract
The utility model relates to an elliptic hydraulic cylinder which comprises a cylinder barrel, a front cylinder cover, a rear cylinder cover, a piston and a piston rod, wherein the front cylinder cover and the rear cylinder cover are respectively positioned at the two ends of the cylinder barrel, the piston is installed in the cylinder barrel, the piston rod is connected with the piston through fixing nuts and then penetrates through the rear cylinder cover, and the molded line of the inner cavity of the cylinder barrel is elliptic. The elliptic hydraulic cylinder is reasonable and simple in structure design and low in manufacturing difficulty and cost, the elliptic inner cavity of the cylinder barrel can reduce the size of the hydraulic cylinder in the radial direction and facilitate installation and arrangement of peripheral hydraulic parts and components, though the appearance is elliptic, the size in the radial direction is reduced, through strict intensity design, intensity requirements can still be met, and reliability is high.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, particularly relates to a kind of oval oil hydraulic cylinder of being convenient to install.
Background technique
At present, oil hydraulic cylinder is important transmission component, is one of important annex of hydraulic system.Yet the inner cavity of cylinder molded lines of oil hydraulic cylinder is commonly circular at present, and under the situation that intensity meets the demands, the circular profile size is bigger, it is big to take up room, easy and other component produce interferes, and when being unfavorable for installing, makes that also the weight and volume of whole hydraulic system is excessive.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, and volume is little, is convenient to install, and satisfies the oval oil hydraulic cylinder of requirement of strength.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise cylinder barrel, front end housing, back cylinder cover, piston and piston rod, front end housing, back cylinder cover lay respectively at the cylinder barrel two ends, piston sleeve is contained in cylinder barrel inside, piston rod by set screw nut with run through back cylinder cover after piston is connected, the inner chamber molded lines of described cylinder barrel is oval.
The utility model has the advantages that:
1, reasonable in design, simple, manufacture difficulty and cost are low;
2, oval-shaped inner cavity of cylinder can reduce oil hydraulic cylinder in the radial direction size, is convenient to the peripheral hydraulic components of mounting arrangements;
Though 3 is oval-shaped profile, size in the radial direction reduces, and the Intensity Design through strict still satisfies requirement of strength, the reliability height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that partly cuts open of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model comprises cylinder barrel 2, front end housing 1, back cylinder cover 5, piston 3 and piston rod 6, front end housing 1, back cylinder cover 5 lay respectively at cylinder barrel 2 two ends, piston 3 is sleeved on cylinder barrel 2 inside, piston rod 6 by set screw nut 4 with run through back cylinder cover 5 after piston is connected, the inner chamber molded lines of described cylinder barrel 2 is oval.
The inner chamber molded lines of the utility model cylinder barrel 2 is oval, can reduce oil hydraulic cylinder in the radial direction size, be convenient to the peripheral hydraulic components of mounting arrangements, though be oval-shaped profile, size in the radial direction reduces, but the Intensity Design through strict still satisfies requirement of strength, the reliability height.
