Being connected in gap and with the 4th parts, the first limit of spring leaf is arranged between second component and rubber bodies
The second gap in and respectively with matrix, second component against the lip hat on, the second limit of spring leaf with rubber bodies
Inner side against.When this utility model uses, purchasing ore is arranged in the seal casinghousing of axle, plays because of interference
Countershaft static seal requirement；Rubber bodies sulfidization molding post-treatment seal lip, meets countershaft static and dynamic sealing and wants
Ask；Spring leaf good springiness, stable performance, spring leaf is elastic greatly, perturbation is good, has preferable footpath
To conformability, under the common effect of rubber bodies and spring leaf, especially after ageing of rubber weares and teares, axle
Large eccentricity, beat greatly time, remain to maintain the interference of seal lip and axle, sealing property is stable, this practicality
Novel be applicable to axle large eccentricity, beat greatly, assembled shaft there is certain angle with hole and axle can move back and forth
Occasion, improve the serviceability of assembly equipment and extend its life-span.
Accompanying drawing explanation
Fig. 1 is the ring structure schematic diagram of a kind of lip string of a hat spring leaf that the utility model proposes.
Detailed description of the invention
With reference to Fig. 1, the utility model proposes the sealing ring of a kind of lip string of a hat spring leaf, including inner frame 1, outward
Skeleton 2, rubber bodies 3 and spring leaf 4, wherein:
The vertical section of inner frame 1 is L-shaped, and inner frame 1 includes first component 101 and second component 102；Outward
The vertical section of skeleton 2 is L-shaped, and purchasing ore 2 includes the 3rd parts 201 and the 4th parts 202, inner frame 1,
Purchasing ore 2 all uses stainless steel insert.First component 101 outer peripheral face and the 3rd parts 201 inner peripheral surface coordinate
Connect, between second component 102 and the 4th parts 202, be reserved with the first gap.The 3rd of purchasing ore 2
Part 201 is provided with the 5th parts 203 away from the 4th parts 202 one end, and the 3rd parts 201 are near the 5th parts
