Background technique
In the prior art, majority does not directly carry out axially locating between the dust-proof cover of Hooke's joint and oil sealing and the outer ring, as a kind of Hooke's joint of being convenient to assemble (patent No.: 01210724.7), it mainly is to be provided with a circlip groove in the mouth inboard, end of outer ring, it is built-in with split washer correspondingly, opening slot also can be arranged on the oil sealing base at this place except being set directly at oral area inboard, outer ring.Mainly between the dust-proof cover of above-mentioned patent and oil sealing and the outer ring realize three's axially locating by split washer, its reliability of positioning is relatively poor, thereby causes the sealing of Hooke's joint and dustproof effect relatively poor.
Summary of the invention
The utility model purpose is to provide a kind of being beneficial between dust-proof cover and oil sealing and the outer ring to locate, be beneficial to the sealing of raising Hooke's joint and the double-hook Hooke's joint outer ring of dustproof effect, it is relatively poor to have solved between dust-proof cover that prior art exists and oil sealing and the outer ring reliability of positioning, thereby causes problems such as the sealing of Hooke's joint and dustproof effect be relatively poor.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: double-hook Hooke's joint outer ring, bottom by tubular wall body and tubular wall body one end constitutes cup-like structure, described tubular wall body opening end outer surface is formed with diameter reducing part, the external diameter of diameter reducing part is less than the external diameter of tubular wall body, the root of diameter reducing part is formed with the outer ring groove, and the internal surface of tubular wall body is provided with interior annular groove near opening end.Wherein, the outer ring groove of outer ring tubular wall body diameter reducing part root can be directly and the internal projecting ring that forms on the dust-proof cover match, interior annular groove then can offset with the end of oil tight skeleton, thereby the double-hook between realization seal ring and oil sealing and the outer ring is directly located, improve the locating effect between the three greatly, improved the sealing and the dustproof effect of Hooke's joint.
As preferably, described between the internal surface of the inner and tubular wall body of annular groove by the inner conical chamfered transition, thereby the end of being convenient to oil tight skeleton enter in the cooperating of formation and interior annular groove in the annular groove.
As preferably, by the external conical shape chamfered transition, enter in the outer ring groove and the outer ring groove fit between the outer end of described outer ring groove and the diameter reducing part thereby be convenient to the dust-proof cover internal projecting ring.
As preferably, chamfering and outer chamfering in described tubular wall body opening end is formed with respectively, thus be convenient to assembling between oil sealing and dust-proof cover and the outer ring.
Therefore, the utlity model has to be beneficial between dust-proof cover and oil sealing and the outer ring and locate, be beneficial to characteristics such as the sealing that improves Hooke's joint and dustproof effect.
