Adopt above-mentioned structure, reduce the lifting surface area of sealing lip, sealing lip is made to be more prone to deformation occurs and is closely abutted together with side wall of shaft sleeve under the acting in conjunction of axle sleeve and outer plate, further increase the sealing connected between outer plate and inner plate, thus improve the working life of this seal ring chain.
In above-mentioned seal ring chain, this one sealing lip near outer plate is positioned at the port of described sealed department.
Namely wherein one sealing lip is positioned at the port of sealed department, the madial wall being positioned at sealed department port is made to form a tapered guide surface, to guarantee that axle sleeve inserts accurately, make together with side wall of shaft sleeve tight abutment, the working life of this seal ring chain to be further increased all the time during sealing lip deformation.
In above-mentioned seal ring chain, between adjacent two seals lip, form the oil storage tank that cross section is V-shape.
Form the groove in V-shape between two adjacent sealing lips, be used for storing grease or storing from the grease flowed out between axle sleeve and bearing pin, improve sealing lip and the sealing be connected between axle sleeve further, thus improve the working life of this seal ring chain.
In above-mentioned seal ring chain, described sealed department outer side wall offers locating slot in the form of a ring, described locating slot is coaxial with sealed department, is provided with jump ring in described locating slot.
Under the effect of jump ring, sealed department has the trend to the movement of axle sleeve direction, sealing lip is closely abutted together with axle sleeve, effectively improves the sealing be connected between sealing lip with axle sleeve, thus improve the working life of this seal ring chain.
Compared with prior art, this seal ring chain has the following advantages:
1, be socketed on the joint that is positioned at outside inner plate by arranging seal ring, seal ring is positioned, seal ring is made under the extruding of outer plate, stably deformation to occur and be formed between outer plate and inner plate stably to seal, effectively avoid the grease between axle sleeve and axle sleeve to volatilize, thus improve the working life of this seal ring chain.
2, the cross section of sealing lip is all triangular in shape, reduce the lifting surface area of sealing lip, sealing lip is made to be more prone to deformation occurs and is closely abutted together with side wall of shaft sleeve under the acting in conjunction of axle sleeve and outer plate, further increase the sealing connected between outer plate and inner plate, thus improve the working life of this seal ring chain.
3, by arranging jump ring, making sealed department have trend to the movement of axle sleeve direction, sealing lip being closely abutted together with bearing pin, effectively improve the sealing be connected between sealing lip with axle sleeve, thus improve the working life of this seal ring chain.
