Abstract
The utility model provides an axle wheel hub oil seal, which relates to the technical field of an oil seal for rotating oil seal shafts. The axle wheel hub oil seal comprises an outer oil seal and an inner oil seal, wherein the outer oil seal and the inner oil seal are assembled on a wheel hub shaft through dimension interference between an inner rubber body lip and a wheel hub shaft, and the axle wheel hub oil seal also comprises a framework which is arranged on a combined oil seal. The position of the inner oil seal is limited through additionally installing the framework on the basis of the original combined oil seal, the relative displacement of the inner oil seal and the outer oil seal is avoided, and the accumulated error in the assembly process is reduced.
Description
Technical field:
The utility model relates to rotary oil seal axle oil encapsulation technique field, is specifically related to the built-up shaft oil sealing that uses on the vehicle bridge wheel hub of heavy goods vehicles.
Background technique:
At present, domestic heavy goods vehicles is when carrying, can not be in strict accordance with specified requirement carrying, shorten serious the exceeding standard of single actual weight into, thereby the vehicle bridge that causes vehicle is being born considerable damage power and is being caused the vehicle bridge hub oil seal to damage or destruction generation leakage of oil, for solving the leakage of oil problem of oil sealing, the assembling before and after two single oil sealings of the technical employing of the oil sealing of wheel hub of most of Railway Car Plant man prevents the inefficacy of oil sealing with the mode of secondary oil sealing.As the oil sealing among the figure one, assemble by outer oil seal 1 and inner oil seal 2, be assembled on the hub spindle by the size interference between interior rubber body lip and the hub spindle, the lip body plays the effect of motive sealing along with hub spindle rotates together simultaneously; Outer oil seal is realized the static seal oil sealing of wheel hub die cavity by outer rubber body and the interference of hub oil seal assembling die cavity.But, the problem that outer oil seal was shifted relatively in the combination oil seal of this class formation press-fited in not in place or the handling process when being prone to assembling.
The model utility content:
The purpose of this utility model provides the vehicle bridge hub oil seal, and the relative displacement of outer oil seal reduced the cumulative error in the assembling process in it can be avoided.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises outer oil seal 1 and inner oil seal 2, outer oil seal 1 and inner oil seal 2 are assembled on the hub spindle by the size interference between interior rubber body lip and the hub spindle, it also comprises skeleton 3, and skeleton 3 is installed on the combination oil seal.
The utility model comes inner oil seal 2 is carried out spacing by install skeleton 5 additional on the basis of original combination oil seal, has avoided the relative displacement of interior outer oil seal, reduces the cumulative error in the assembling process.
Description of drawings:
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 2, this embodiment is by the following technical solutions: it comprises outer oil seal 1 and inner oil seal 2, outer oil seal 1 and inner oil seal 2 are assembled on the hub spindle by the size interference between interior rubber body lip and the hub spindle, and it also comprises skeleton 3, and skeleton 3 is installed on the combination oil seal.
This embodiment is come inner oil seal 2 is carried out spacing by install skeleton 3 additional on the basis of original combination oil seal, has avoided the relative displacement of interior outer oil seal, reduces the cumulative error in the assembling process.
