(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a piston rod sealing washer of hydraulic cylinder, including sealing washer outer loop and polytetrafluoroethylene granule, it has the wearing layer to connect on a sealing washer outer loop lateral wall, the embedded rubber supporting layer that has in wearing layer bottom, the shaping has the smooth layer on the sealing washer outer loop inside wall, the shaping has the inner ring on the smooth layer, it has to embed on an inner ring lateral wall the polytetrafluoroethylene granule.
By adopting the technical scheme, the rubber supporting layer is a supporting structure of the sealing ring, the smooth layer is used for facilitating the installation of the sealing ring, and the polytetrafluoroethylene particles have tension, and are wear-resistant, high-temperature-resistant and corrosion-resistant.
Furthermore, high temperature resistant layers are clamped and pressed on two sides of the rubber supporting layer.
By adopting the technical scheme, the high-temperature-resistant layer can improve the high-temperature resistance of the device.
Furthermore, the other two side walls of the outer ring of the sealing ring are glued and connected with elastic outer walls.
Through adopting above-mentioned technical scheme, the impact force that the sealing washer received is used for alleviateing to the elasticity outer wall.
Furthermore, a sealing inner gasket is clamped and pressed between the elastic outer walls.
Through adopting above-mentioned technical scheme, sealed inner packing is used for the oil of sealed cylinder body.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
for the antifouling, wear-resisting and the main seal assembly who solves piston rod among the current pneumatic cylinder when the piston rod does work, can cause seal assembly's portability after long-time, lead to sealed degree inhomogeneous, reduced the problem of the effect of density, the utility model discloses a set up polytetrafluoroethylene granule, can improve seal assembly's resiliency, when the piston rod is the piston motion of high-speed high strength, avoid causing deformation damage to seal assembly, ensured seal assembly's intact.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 to fig. 3, the seal ring for the piston rod of the hydraulic cylinder in the present embodiment includes a seal ring outer ring 1 and polytetrafluoroethylene particles 4, a wear-resistant layer 3 is glued on a side wall of the seal ring outer ring 1, and a rubber support layer 9 is embedded in the bottom of the wear-resistant layer 3. The rubber support layer 9 is a support structure of the seal ring. The high temperature resistant layer 8 is clamped and pressed on two sides of the rubber supporting layer 9. The high temperature resistant layer 8 can improve the high temperature resistance of the device. The other two side walls of the outer ring 1 of the sealing ring are glued with elastic outer walls 5, and the elastic outer walls 5 are used for reducing the impact force on the sealing ring. The card is pressed between the elastic outer wall 5 and is had sealed interior pad 6, and sealed interior pad 6 is used for the oil of sealed cylinder body, and the shaping has smooth layer 7 on 1 inside wall of sealing washer outer loop, and smooth layer 7 makes things convenient for the installation of sealing washer, and the shaping has inner ring 2 on smooth layer 7, and 2 lateral walls of inner ring are gone up to be embedded to have polytetrafluoroethylene granule 4, and polytetrafluoroethylene granule 4 has tension, wear-resisting, high temperature resistant and corrosion-resistant moreover.
The specific implementation process of this embodiment is as follows: install the device on the piston rod at first, then with the piston rod installation with the pneumatic cylinder in, make the sealing washer coincide with the slotted hole seal on the cylinder cap, can accomplish the installation, wherein inner ring 2 relies on the elastic tension of polytetrafluoroethylene granule 4 in the slotted hole, make the sealing washer when the gap between sealed piston rod and the cylinder body, play the effort of a buffering, avoid taking place deformation and leading to local position to take place the skew because of the sealing washer, avoid taking place the phenomenon of oil leak, and smooth layer 7 can order about the sealing washer rotatory when the cylinder body relative slip, rather than receiving same power repeatedly in a position, and then ensured the intact of seal assembly.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
