Abstract
The utility model discloses a kind of sealing structure of shaft end of running shaft, comprise the running shaft be arranged on casing, between running shaft and casing, tapered roller bearing is installed, the axle head of running shaft is provided with sealing flange, and described sealing flange external annular surface and casing inner ring surface are equipped with single lip outside framework oil seal.The utility model adds sealing flange external annular surface and casing inner ring surface is equipped with single lip outside framework oil seal at running shaft axle head, leak for stoping the oil in Seal cage, and increase dust-proof seal ring, Seal cage is entered in impurity such as preventing extraneous steam dust, because described dust-proof seal ring is pressed between sealing flange and casing end face, add that the resilience of himself rubber material is stronger, himself meeting auto-compensation when dustproof seal ring has wearing and tearing, not only seal action strengthens, and substantially increases serviceability and reliability.
Description
Technical field
The utility model relates to a kind of sealing configuration of mechanical mechanism, specifically a kind of sealing structure of shaft end of running shaft.
Background technique
At the gearbox of mechanical field, speed reducers etc. need in the device of lubrication, shaft sealing oil sealing is indispensable component, input at mechanical transmission at present, the oil sealing that output terminal adopts normally seals the Double-lip framework oil sealing that lip adds dust excluder lips, dust excluder lips is used for preventing the impurity such as extraneous steam dust from entering Seal cage, envelope lip leaks for stoping the oil in Seal cage, but due to the restriction of himself structure, poor and the auto-compensation scarce capacity of the anti-dust performance of dust excluder lips, cause this sealing configuration at the more environment lower seal weak effect of the impurity such as dust and serviceability is low.
Summary of the invention
For above-mentioned existing issue, the utility model provides a kind of sealing structure of shaft end of running shaft, can effectively improve the impurity such as dust and serviceability effective compared with multi-environment lower seal and reliability high.
To achieve these goals, the technical solution adopted in the utility model is: a kind of sealing structure of shaft end of running shaft, comprise the running shaft be arranged on casing, between running shaft and casing, tapered roller bearing is installed, the axle head of running shaft is provided with sealing flange, and described sealing flange external annular surface and casing inner ring surface are equipped with single lip outside framework oil seal.
O type circle is housed between described running shaft and sealing flange.
Between described sealing flange end face and casing end face, dust-proof seal ring is housed.
Described sealing flange is arranged on the axle head of running shaft by bolt
The utility model adds sealing flange external annular surface and casing inner ring surface is equipped with single lip outside framework oil seal at running shaft axle head, leak for stoping the oil in Seal cage, dust-proof seal ring is increased between described sealing flange end face and casing end face, Seal cage is entered, single lip outside framework oil seal and the coefficient compound sealing structure of dust-proof seal ring 5 in impurity such as preventing extraneous steam dust.Because described dust-proof seal ring is pressed between sealing flange and casing end face, add that the resilience of himself rubber material is stronger, himself meeting auto-compensation when dustproof seal ring has wearing and tearing, not only seal action strengthens, and substantially increases serviceability and reliability.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, running shaft, 2, tapered roller bearing, 3, casing, 4, single lip outside framework oil seal, 5, dust-proof seal ring, 6, sealing flange, 7, O shape circle.
Embodiment
Be described in further detail below by accompanying drawing 1 pair of the technical solution of the utility model (comprising optimal technical scheme).
As shown in Figure 1, the sealing structure of shaft end of the utility model running shaft, comprise casing 3, be arranged on the running shaft 1 on casing 3, and the sealing flange 6 of running shaft 1 axle head is arranged on by bolt, be provided with tapered roller bearing 2 between described running shaft 1 and casing 3, described sealing flange 6 external annular surface and casing inner ring surface are equipped with outside framework oil seal 4, and described sealing flange 6 end face and casing 3 end face are equipped with dust-proof seal ring 5.
In addition, in order to prevent the seepage of the oil in Seal cage, O type circle being housed between running shaft and sealing flange, sealing.
In specific implementation process, single lip outside framework oil seal 4 stops the oil in Seal cage to leak, dust-proof seal ring 5 enters Seal cage for preventing the impurity such as extraneous steam dust, because described dust-proof seal ring 5 is pressed between sealing flange 6 and casing 3 end face, add that the resilience of its rubber material self is comparatively strong, therefore not only sealing is very high, and himself understands auto-compensation when dustproof seal ring 5 has wearing and tearing, ensure the sealing of structure, substantially increase serviceability and reliability.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope of the utility model request protection.
