Description
Technical field
The utility model relates to a kind of Hooke's joint, belongs to coupling, relates in particular to a kind of improvement to Hooke's joint dust-proof cover and dependency structure thereof.
Background technique
The Hooke's joint (patent No. 01210725.5) of band dust-proof cover, comprise cross axle, the dust-proof cover of being located at needle roller and the outer ring on the cross axle spindle nose and being arranged at mouth end, outer ring, it is characterized in that described dust-proof cover system is made of cover body face that is provided with axis hole and the ring around it and the bulge loop of being located at the ring inboard, and be provided with and the corresponding mating groove of bulge loop at the outer rim place of mouth end, outer ring.And with the Hooke's joint (patent No. 01210729.8) of many lip seals circle, relate to the Hooke's joint that a kind of dustproof, anti-lubricating grease leaks, it mainly is that oral area in described outer ring is provided with the sealing skeleton, be built-in with mulit-lip seal ring, described mulit-lip seal ring system is epipharynx that Eight characters shape distributes and middle lip by the cross section and forms with middle lip outer lip in the same way, the arc groove bottom of the outer arc groove between inner arc groove therebetween, middle arc groove and outer lip and sealing skeleton apart from seal skeleton apart from distribution gradient.Heavy universal joint on above-mentioned Hooke's joint and the existing market is for guaranteeing its life requirements, seal request to product is higher, generally most in design employing two lip dust-proof cover add inner oil seal and seal together, dust-proof cover is fixed by a jump ring simultaneously, the dustproof effect of this kind structure still can, but fixedly jump ring very easily comes off in the assembling and dissembling process of product, and the assembling and the use of product exerted an influence.
Summary of the invention
The utility model mainly is to solve in the existing in prior technology cross axle assembling and dissembling process technical problem that fixing jump ring very easily comes off etc., provides a kind of sealing effect good, simple load and unload Hooke's joint with many lips dust-proof cover.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: with the Hooke's joint of many lips dust-proof cover, be arranged between spindle nose and the outer ring, comprise cross axle, the dust-proof cover of being located at needle roller and the outer ring on the cross axle spindle nose and being arranged at mouth end, outer ring, it is characterized in that between described outer ring mouth and cross axle step, being provided with oil tight skeleton, between oil tight skeleton and cross axle, be provided with oil sealing, described oil tight skeleton is the U-shaped structure, and described dust-proof cover comprises the middle lip circle that is embedded in the oil tight skeleton, the inner lip circle that cooperates with the cross axle step and with the outer lip circle that cooperates the inclined-plane to cooperate at the outer rim place that is located at mouth end, described outer ring.Wherein said dust-proof cover with many lips circle utilizes the cooperation of inner lip circle, middle lip circle and outer lip circle, can play the fixing effect of good sealing and dustproof effect and dust-proof cover self, thereby makes mounting or dismounting convenient.
As preferably, described inner lip circle is axial uniform thickness shape, is provided with an axial notch between inner lip circle and middle lip circle, and the axis hole wall of described dust-proof cover cooperates with the cross axle step, forms the first road sealing and dustproof effect.The inner lip circle that wherein is axial uniform thickness shape has more elasticity, and groove not only can be saved the material of making dust-proof cover, has also increased the elasticity of inner lip circle simultaneously.
As preferably, described in lip circle axial cross section be trapezoid shaped, it stretches into oil tight skeleton and cooperates with the oil tight skeleton wall, forms the second road sealing and dustproof effect, the while is also with the fixation of dust-proof cover self.
As preferably, the axial cross section of described outer lip circle is a wedge shape, and its internal surface cooperates with the inclined-plane that cooperates at outer rim place, mouth end, outer ring.Though wherein in the process of using, relative movement is arranged between outer lip circle and the outer ring, but be the inclined-plane cooperation because described outer lip circle cooperates with the outer ring, and cooperate wall thinner, overlay on the inclined-plane, outer ring, so also play good dustproof and waterproof effect, form the dustproof effect in the 3rd road.
As preferably, described oil sealing is many lip seals circle, and it is made of four lips that are axial distribution, is provided with three road grooves therebetween, and the interim orbit groove is darker, and side twice groove is more shallow.Wherein the oil sealing of four lips has strengthened the effect of sealing and dustproof.
Characteristics such as therefore, the utlity model has rational in infrastructurely, sealing and dustproof is respond well, and mounting or dismounting are convenient.Wherein the axis hole wall of dust-proof cover cooperates with the cross axle step, form the first road sealing and dustproof effect, middle lip circle axial cross section is a trapezoid shaped, it stretches into oil tight skeleton and cooperates with the oil tight skeleton wall, form the second road sealing and dustproof effect, also dust-proof cover is fixed simultaneously, the axial cross section that is aided with the outer lip circle is a wedge shape, and its internal surface cooperates with the inclined-plane that cooperates at the outer rim place of mouth end, outer ring.Though wherein in the process of using, relative movement is arranged between outer lip circle and the outer ring, but be the inclined-plane cooperation because described outer lip circle cooperates with the outer ring, and cooperate wall thinner, overlay on the inclined-plane, outer ring, so also play good dustproof and waterproof effect, form the dustproof effect in the 3rd road.
