Abstract
The utility model discloses a sealing device for a hydraulic cylinder guide sleeve, belonging to the sealing devices. The sealing device for the hydraulic cylinder guide sleeve comprises the guide sleeve, a piston rod matched with the guide sleeve in a slide way, and a sealing device body arranged on the inner cylindrical surface of the guide sleeve, wherein the sealing device body comprises a dust seal arranged on the end face of the guide sleeve, a rod seal at the inner side of the dust seal, and a buffer seal; the dust seal adopts a DKBI3-type wiper scraper seal; the rod seal adopts an IUH high pressure oil seal; and the buffer seal adopts an HBY buffering ring. The sealing device for the hydraulic cylinder guide sleeve, disclosed by the utility model, has the beneficial effects that the structure is simple, the waterproof and dustproof effects are favorable, the installation is convenient, loss caused by failure of the sealing of a hydraulic cylinder because of rusting, oil leak, and the like is greatly reduced, and the reliability and the safety of the hydraulic cylinder are greatly enhanced.
Description
Technical field
The utility model relates to a kind of seal arrangement, and a kind of hydraulic cylinder guide sleeve seal arrangement specifically is mainly used in the sealing of excavator hydraulic cylinder guide sleeve and axle.
Background technique
Crawler hypraulic excavator is the main construction plant in the earth and rock works construction, approximately finishes 60% earth and rock works amount.Medium-and-large-sized excavator is widely used in the economic construction of national every profession and trade, in the earth and rock works of building railway, highway, hydroelectric power, mine excavation, airport, the disaster relief etc., plays a significant role.Along with the quickening of China's economic construction paces and the pulling of government investment, the going into operation of big-and-middle-sized infrastructure, the hydraulic excavator market demand also will have very large growth, and mainly take middle large tonnage product as main.
At present, domestic excavator hydraulic cylinder guide sleeve mostly adopts the conventional seals configuration, and hydraulic cylinder works is frequent at work, impact is large owing to excavator.And excavator hydraulic cylinder is the bindiny mechanism that supports the various motions of excavator, oil hydraulic cylinder in the work is because work is frequent, impact is large, very easily produce the sealing back pressure, in the course of time guide sleeve sealing will be lost efficacy, cause oil hydraulic cylinder generation leakage of oil and guide sleeve corrosion, causing complete machine can't work, and makes troubles to construction operation, gives client's economic loss.
Summary of the invention
The utility model provides a kind of hydraulic cylinder guide sleeve seal arrangement, and purpose is to make it have better antirust, decompression function, improves product reliability, Security and working life.
The utility model is realized with following technological scheme: a kind of hydraulic cylinder guide sleeve seal arrangement, it comprises guide sleeve, the piston rod that is slidingly matched with guide sleeve, be installed in the seal arrangement on the inner cylindrical surface of guide sleeve, described seal arrangement is become with the buffering sealing group by the dust sealing that is positioned at the guide sleeve end face, the rod seal that is positioned at the dust sealing inboard; Described dust sealing adopts DKBI3 type dust ring; Described rod seal adopts the IUH High-pressure oil sealing; The HBY buffering ring is adopted in described cushion seal.
Technique scheme adopts the axle seal arrangement of DKBI3+IUH+HBY sealing collocation, and DKBI3 type dust ring has well antirust, decompression function, and the IUH Sealing more meets domestic manufacturing technology level on material, function.This configuration has solved the shortcomings such as easily the getting rusty of conventional arrangement, leakage of oil.Not only improve the reliability and safety of product, and be beneficial to the lifting of product total quality level.
The beneficial effects of the utility model are: simple in structure, waterproof and good dustproof effect, easy for installation, greatly reduce because of the hydraulic cylinder sealing that gets rusty, the inefficacy such as leakage of oil the causes loss that brings etc. of losing efficacy, greatly improved reliability, Security and the quality level of product.
Description of drawings
Below in conjunction with drawings and Examples the utility model structure is further specified.
Accompanying drawing is the hydraulic cylinder guide sleeve schematic diagram of sealing device.
Among the figure: 1, piston rod, 2, guide sleeve, 3, buffering ring, 4, rod seal, 5, dust sealing.
Embodiment
As shown in drawings, the hydraulic cylinder guide sleeve seal arrangement is that the sealing device is comprised of dust sealing 3, rod seal 4 and cushion seal 5 at piston rod 1 and 2 of guide sleeves, i.e. mounting sealing device on the inner cylindrical surface at guide sleeve; Dust sealing 3 adopts DKBI3 type dust ring; Rod seal 4 adopts the IUH High-pressure oil sealing; The HBY buffering ring is adopted in cushion seal 5.Dust sealing 3 is positioned at the end face of guide sleeve 2, is rod seal 4 and cushion seal 5 in dust sealing 3 inboards.
This configuration has solved the shortcomings such as easily the getting rusty of conventional arrangement, leakage of oil.Not only improve the reliability and safety of product, and be beneficial to the lifting of product total quality level.
