Abstract
The utility model provides an axel shaft oil seal which comprise a metal frame and a rubber body. An oil seal is formed by the metal frame and the rubber body. A main lip opening is arranged at the bottom of the inner lateral side of the oil seal, an oil seal spring is arranged on the outer lateral face of the main lip opening, and a dust-proof opening is arranged on an air lateral face of the oil seal. The perpendicular distance between the main lip opening of the oil seal and an A surface ranges from 3.7mm to 4.1mm, and the thickness of the section at a waist position ranges from 0.8mm to 1.2mm. The minimum of the tensile stress of the oil seal spring ranges from 1.47N to 1.94N, and the maximum of the tensile stress of the oil seal spring ranges from 2.03N to 2.63N. The rubber body, the oil seal lip opening and the dust-proof opening are made of fluororubber. The axel shaft oil seal has the advantages of improving anti-eccentric capacity, fast filling gaps caused by big eccentricity, and having good following performance, is suitable for working in sealing environment with the total run lower than 0.60mm and the shaft diameter between phi 40 and phi 90, and has sealing effects.
Description
Technical field
This practical a kind of axle-shaft oil seal is a kind of rotation axis seal parts that are applied to the automobile axle shaft place.
Background technique
At present, in automobile industry, there is keyway automobile axle shaft the inner, and is engaged with the interior spline of differential gear, accepts the power that differential mechanism (or initiative taper) transmits respectively.There is flange the outer end, is connected with bolt with wheel hub, and driving wheel is rotated.From the purposes of semiaxis as can be seen, semiaxis will bear very big moment of torsion, forces the wheel rotation and makes automobile running.Special commercial car semiaxis is long, and dynamically beating of being produced in operation process is big, generally greater than 0.5mm, is used for the rear axle shaft oil sealing, and the width spaces of assembling because of oil sealing is restricted, and is not suitable for adopting the oil sealing of floating structure; In addition, a lot of oil sealing factories are because the standardization of oil sealing external diameter height, cause most oil sealing factory to have following defective when structural design: (1) waist length is too short, (2) the waist section is blocked up, phenomenon such as (3) the lip magnitude of interference is unreasonable can not satisfy semiaxis and have the big usage requirement of dynamically beating.
The oil sealing that waist length is too short, waist thickness is blocked up is poor to following of axle; The oil sealing eccentric operating is inevitably, so just causes the fluctuation of oil sealing lip cutting edge, causes the oil sealing waist to bear strong deflecting, and simultaneously, the oil sealing waist also will bear the caused torsional deflection of surface friction drag between lip and the axle, destroys the sealing of oil sealing.Magnitude of interference is excessive, will cause lip too to stretch, and radial pressure strengthens, the wearing and tearing aggravation, and a large amount of frictional heats causes the ageing hardening of sizing material, early stage be full of cracks is leaked at last; Magnitude of interference is little, and oil seal lip touches the gap and becomes big with being coupling, and it is big that the oil slick thickness of formation becomes, and oil film tension force diminishes and leaks.Therefore, oil seal lip magnitude of interference and oil sealing lip configurations are to be mutually related, and should take all factors into consideration.
Summary of the invention
The utility model proposes a kind of axle-shaft oil seal, its objective is in order to improve anti-eccentric force and resistance to pressure, solve because at high temperature, at a high speed, the problem of sealing failure during the large eccentricity amount.
The technical solution of the utility model is for this reason, a kind of axle-shaft oil seal, comprise metal frame, rubber body, rubber body and metal frame are formed oil sealing jointly, it is characterized in that: be provided with main lip in the oil sealing inside bottom, the outer side surface of main lip is provided with oil seal spring, and the air side of oil sealing is provided with dustproof mouthful.
Improvement to such scheme is: the perpendicular distance of described main lip and A face is 3.7～4.1mm; The waist section thickness is 0.8～1.2mm.
Improvement again to such scheme is: the minimum value of oil seal spring tensile stress is between 1.47N-1.94N, and maximum value is between 2.03N-2.63N.
Further improvement of these options is: rubber body and main lip and dustproof mouth all adopt fluorine rubber to make.
The utility model axle-shaft oil seal, sealing material adopts fluorine rubber, the waist Design of length is 3.7～4.1mm, the waist section thickness is designed to 0.8～1.2mm, has improved the anti-eccentric ability of axle-shaft oil seal, has filled up the gap that produces because of large eccentricity rapidly, oil sealing has good followability, be suitable for axle, the total jerk value≤0.60mm of seat, work under ∮ 40≤diameter of axle≤∮ 90 sealed environments, play the characteristics of effective sealing.
The oil seal spring tensile stress increases by 5%～10%, the tensile stress of spring 5% is increased to 1.47N～1.94N on original basis, 10% tensile stress is increased to 2.03N～2.63N on original basis, compensate because oil sealing waist length increases with waist thickness to reduce the oil sealing radial force that reduced.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a partial cutaway schematic of the present utility model.
The 1st, metal frame, the 2nd, oil seal spring, the 3rd, rubber, the 4th, main lip, 5 dustproof mouthfuls.
Embodiment
The utility model as shown in Figure 1 and Figure 2.
A kind of axle-shaft oil seal, comprise metal frame 1, oil seal spring 2, rubber body 3, rubber body 3 and the metal frame 1 common oil sealing of forming are to be provided with main lip 4 in the oil sealing inside bottom, the outer side surface of main lip 4 is provided with oil seal spring 2, and the air side of oil sealing is provided with dustproof mouthful 5.
Wherein main lip 4 is 3.7～4.1mm with the perpendicular distance of A face; Waist thickness is 0.8～1.2mm.
The oil seal spring tensile stress increases by 5%～10%.The tensile stress of spring 5% is increased to 1.47N～1.94N on original basis, 10% tensile stress is increased to 2.03N～2.63N on original basis.
Rubber body and main lip and dustproof mouth all adopt fluorine rubber to make.
The utility model rubber body sealing material adopts fluorine rubber to become an integral body with metal frame two-part with the mould molded vulcanization, and the secondth, post vulcanization, the 3rd is deburring, inspection, overlaps the oil seal spring finished product at last.
