Abstract
The utility model relates to a sealing component, in particular to a split-type combined oil seal, which comprises an outer oil seal and an inner oil seal. The outer oil seal and the inner oil seal are combined, wherein the outer oil seal comprises an outer skeleton, a spring and an outer rubber sealing body, and the inner oil seal comprises an inner skeleton and an inner rubber sealing body. The split-type combined oil seal is characterized in that the upper bottom surface of the inner oil seal and the lower bottom surface of the outer oil seal are tightly contacted and matched to form an integrated type combined structure, and the outer rubber sealing body of the outer oil seal is provided with a radial concave hole. Due to the improvement based on the original oil seal, the split-type combined oil seal has good dustproof effect and sealing performance, and the demands of dusty working conditions can be satisfied.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of split combination oil seal.
Background technique
Present oil sealing, mostly be the single sealing configuration of forming by skeleton, spring and rubbery sealed body, it is under the more working condition of dust, dustproof effect is relatively poor, can not satisfy the demand of actual conditions, the oil sealing that for this reason needs a kind of dustproof effect and good seal performance satisfies the demand of the more working condition of dust.
The model utility content
Split combination oil seal of the present utility model, it makes it can have good dust-proof effect and sealability by the improvement to original oil sealing, can satisfy the demand of the more working condition of dust.
The technological scheme that the utility model adopted is:
The split combination oil seal, the outer oil seal and the inner oil seal that comprise mutual combination, wherein outer oil seal is made up of outer skeleton, spring and outer rubber seal, inner oil seal is made up of inner frame and interior rubbery sealed body, it is characterized in that: the mutually tight contact matching of the upper bottom surface of inner oil seal and the bottom surface of outer oil seal forms the integral type composite structure, and the outer rubber seal of outer oil seal is provided with radial pocket.
Like this in when work, split combination oil seal of the present utility model, an outer oil seal master lip and an axle interference fit play sealing lubricating oil; Outside lip of inner oil seal and outer oil seal interference fit play dustproof effect; The outer rubber seal of outer oil seal is provided with radial pocket, can avoid movement process to produce negative pressure; The mutually tight contact matching of the upper bottom surface of inner oil seal and the bottom surface of outer oil seal forms the integral type composite structure, further plays the good dust-proof effect.
Split combination oil seal of the present utility model, it makes it can have good dust-proof effect and sealability by the improvement to original oil sealing, can satisfy the demand of the more working condition of dust.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is original oil seal structure schematic representation;
Fig. 2 is a split combination oil seal structural representation of the present utility model.
Among the figure, 1 is outer oil seal, and 2 is inner oil seal, and 3 is outer skeleton, and 4 is spring, and 5 is the outer rubber seal, and 6 is inner frame, and 7 is interior rubbery sealed body, and 8 is radial pocket, and 9 is outer oil seal master lip, and 10 is the outside lip of inner oil seal, and 11 is skeleton, and 12 is rubbery sealed body.
Embodiment
Embodiment
As shown in Figure 1, be original oil sealing, it is the single sealing configuration of being made up of skeleton 11, spring 4 and rubbery sealed body 12, and it is under the more working condition of dust, and dustproof effect is relatively poor, can not satisfy the demand of actual conditions.As shown in Figure 2, be split combination oil seal of the present utility model, the outer oil seal 1 and the inner oil seal 2 that comprise mutual combination, wherein outer oil seal 1 is made up of outer skeleton 3, spring 4 and outer rubber seal 5, inner oil seal 2 is made up of inner frame 6 and interior rubbery sealed body 7, it is characterized in that: the mutually tight contact matching of the bottom surface of the upper bottom surface of inner oil seal 2 and outer oil seal 1 forms the integral type composite structure, and the outer rubber seal 5 of outer oil seal 1 is provided with radial pocket 8.
Like this in when work, split combination oil seal of the present utility model, an outer oil seal master lip 9 and an axle interference fit play sealing lubricating oil; Outside lip 10 of inner oil seal and outer oil seal 1 interference fit play dustproof effect; The outer rubber seal 5 of outer oil seal 1 is provided with radial pocket 8, can avoid movement process to produce negative pressure; The mutually tight contact matching of the bottom surface of the upper bottom surface of inner oil seal 2 and outer oil seal 1 forms the integral type composite structure, further plays the good dust-proof effect.
Split combination oil seal of the present utility model, it makes it can have good dust-proof effect and sealability by the improvement to original oil sealing, can satisfy the demand of the more working condition of dust.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
