Abstract
The invention discloses a steering oil cylinder of a loader, and is characterized in that a piston rod is arranged in a cylinder barrel, one end of the piston rod is locked with a piston through a lock nut, the piston rod is sleeved in the cylinder barrel through a guide sleeve, a dustproof ring, a step seal, a first support ring, a piston rod sealing ring,, an O-shaped ring and a retainer ring are arranged in grooves at the outer diameter and the inner diameter of the guide sleeve, and the piston is provided with a glyd ring and a second support ring. Through the setting, the steering oil cylinder has the advantages of good sealing property, simple and compact structure and difficulty in looseness of the piston, and conforms to special working requirements of the steering oil cylinder.
Description
Technical field
The present invention relates to oil cylinder of loading machine, is specifically related to the steering cylinder of loader.
Background technique
Present loader longevity of service, frequency of okperation is high, poor working environment, steering cylinder requires it must have the characteristics such as good seal performance, long working life, compact structure in complete machine.
Summary of the invention
The present invention is directed to the present real work situation of loading machine steering oil cylinder, designed and developed out good seal performance, oil cylinder simple and compact for structure.
The present invention is achieved by the following technical solutions:
Inside at cylinder barrel is provided with piston rod, end at piston rod has piston by locking nut locking, piston rod is linked in the cylinder barrel by guide sleeve, dust ring, this special envelope, the first support ring, rod seal circle, O type circle, back-up ring are installed in the external diameter of guide sleeve and internal diameter groove, at piston Glais ring, the second support ring 13 are installed.
By above setting, good seal performance of the present invention, simple and compact for structure, piston is difficult for loosening, meets particular job requirement of steering cylinder.
Description of drawings
Now the invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
Among the figure: 1, cylinder barrel, 2, piston rod, 3, locking nut, 4, piston, 5, guide sleeve, 6, dust ring, 7, this special envelope, the 8, first support ring, 9, the rod seal circle, 10, O type circle, 11, back-up ring, 12, Glais ring, the 13, second support ring.
Embodiment
As shown in Figure 1, the present invention is provided with piston rod 2 in the inside of cylinder barrel 1, end at piston rod 2 has piston 4 by locking nut 3 lockings, piston rod 2 is linked in the cylinder barrel by guide sleeve 5, dust ring 6, this special envelope 7, first support ring 8, rod seal circle 9, O type circle 10, back-up ring 11 are installed in the external diameter of guide sleeve 5 and internal diameter groove, at piston 4 Glais ring 12, the second support ring 13 are installed.By above setting, when the present invention stretched out and retracts when piston rod 2, the Glais ring 12 on the piston 4 played the primary seal effect, and the second support ring 13 provides lateral support; Dust ring 6 on the guide sleeve 5 strikes off introduced contaminants, prevents from entering damaging sealing in the oil cylinder, and rod seal circle 9 compresses piston rod 2 and guide sleeve 5 under fluid pressure, reach sealing purpose.
