Abstract

The utility model relates to a split oil seal with a double outer lip opening and without a framework, which belongs to oil seals and comprises a split seal body and an inner spring ring. The split oil seal is characterized in that a circular arc groove is arranged on the middle circumference of an outer circumferential face (outer lip) of the split seal body (namely an upper semi-circle seal body and a lower semi-circle seal body), the outer circumferential faces of the left side and the right side of the circular arc groove is led to be the double outer lip openings in a shape of a circular arc flange, an outer spring ring is installed in the circular arc groove, the outer spring ring is a spiral spring or a retaining ring type spring, the double outer lip opening has a seal effect, so that the split oil seal is good in sealing and long in service life.

Description

The split type oil sealing of exoskeletal pair of outer lip
Technical field
The utility model belongs to oil sealing, especially relates to a kind of split type oil sealing.
Background technique
Existing split type oil sealing is made up of the seal of skeleton and split type usually, but the outer lip of sealing body (being outer circumferential face) is the plane; When this split type oil sealing is installed, need elder generation that the seal of oil sealing is pushed toward the inner chamber of oil sealing base hole from axle, so seal often produces deviation because of unbalance stress; Skeleton is installed then; In case running is used, be prone to ooze, oil leakage phenomenon, sealing effect is relatively poor and reduced oil sealing working life.
Summary of the invention
The purpose of the utility model is the split type oil sealing that proposes a kind of exoskeletal pair of outer lip, and is not only simple in structure, easy for installation, and good airproof performance, long service life.
The purpose of the utility model realizes like this: a kind of split type oil sealing of exoskeletal pair of outer lip; Comprise split type seal and inner spring circle; Be that the sealing body goes to upper and lower semi-round ring shape; Suit inner spring circle on the epipharynx of this split type seal; This inner spring circle is helical spring or snap ring type spring, it is characterized in that: the middle part circumference at the outer circumferential face (being outer lip) of this split type seal (promptly at upper and lower semi-round ring shape seal) is offered circular groove and is made the outer circumferential face of this circular groove left and right sides become the two outer lips that are the circular arc flange, and the outer spring circle is installed in this circular groove; This outer spring circle also can be helical spring or snap ring type spring, and this pair outer lip seals.
During installation, this partly cuts open the formula seal to stretch out earlier on the shaft part in oil sealing base hole suit outside, and corresponding inside and outside spring ring is installed; Make it to fuse, then this is partly cutd open the formula oil sealing and rely on external force to push in the inner chamber in oil sealing base hole into, though can deviation occur because of unbalance stress; But at epipharynx; Because of the effect of inner spring circle and inner lip is arranged, the oil sealing inboard can leakage of oil, and the corresponding compensation effect is arranged; Outer lip, because of outside the sealing of lips mouth, can effectively compensate the deviation that causes because of unbalance stress, add the effect of outer spring circle on the other hand, make the sealing effect of this split type oil sealing reach best.
The split type oil sealing of the exoskeletal pair of outer lip that the utility model proposed, rational in infrastructure, installation, easy to use, and good airproof performance, long service life.
Combine accompanying drawing and embodiment that the split type oil sealing of the exoskeletal pair of outer lip that the utility model proposed is described further at present.
Description of drawings
Fig. 1 is the main cross-sectional schematic of the split type oil sealing of exoskeletal pair of outer lip proposing of the utility model.
Among Fig. 1: 1, inner spring circle 2, split type seal 3, outer spring circle 4, inner lip 5, outer lips mouth.
Embodiment
As can be seen from Figure 1: a kind of split type oil sealing of exoskeletal pair of outer lip; Comprise split type seal 2 and inner spring circle 1; Be that the sealing body goes to upper and lower semi-round ring shape; Suit inner spring circle 1 on the epipharynx of this split type seal 2; This inner spring circle 1 is helical spring or snap ring type spring, it is characterized in that: the middle part circumference at the outer circumferential face (being outer lip) of this split type seal 2 (promptly at upper and lower semi-round ring shape seal) is offered circular groove and is made the outer circumferential face of this circular groove left and right sides become the two outer lips 5 that are the circular arc flange, and outer spring circle 3 is installed in this circular groove; This outer spring circle 3 also can be helical spring or snap ring type spring, and this pair outer lip 5 seals.
During installation, this partly cuts open formula seal 2 to stretch out earlier on the shaft part in oil sealing base hole suit outside, and corresponding inside and outside spring ring 1,3 is installed; Make it to fuse, then this is partly cutd open the formula oil sealing and rely on external force to push in the inner chamber in oil sealing base hole into, though can deviation occur because of unbalance stress; But at epipharynx; Because of the effect of inner spring circle 1 and inner lip 4 is arranged, the oil sealing inboard can leakage of oil, and the corresponding compensation effect is arranged; At outer lip, because of the sealing of outer lips mouth 5, can effectively compensate the deviation that causes because of unbalance stress, add the effect of outer spring circle 3 on the other hand, make the sealing effect of this split type oil sealing reach best.
