Side and mounting shell Interference contact, have seal lip and be positioned at the dust-proof lip below seal lip, sealing lip inside outer oil seal
Mouthful and the equal sealing shroud of dust-proof lip outside inner oil seal, and outside seal lip, dust-proof lip and inner oil seal between there is lubrication
Oil, outer oil seal Basolateral has ring fillister, and purchasing ore top is enclosed within cannelure, and outer oil seal bottom is provided with ring-shaped rubber
Projection, purchasing ore bottom is bent to form spacing ring, and turn up formation locating ring in inner oil seal bottom, and locating ring top and bottom are respectively
With bottom rubber bumps and spacing ring top interference fits.
Utilize inner oil seal and outer oil seal to be connected with installation axle and mounting shell respectively, utilize inner oil seal and outer oil seal afterwards
Contact seals, the effective problem solving abradable seal axial plane, utilizes rubber bumps and spacing ring to limit locating ring respectively simultaneously
Relative movement space, to facilitate installation, it is ensured that assembles and puts in place, prevents lubricating oil from leaking the leakage of oil caused, to improve sealing effectiveness.
In above-mentioned a kind of Novel box-type oil sealing, described outer oil seal includes rubber bodies one and support frame one, rubber
Body one is coated on outside support frame one, and with mounting shell Interference contact outside rubber bodies one, cannelure is located at rubber bodies one bottom
Outside, the rubber bodies one at the seal lip back side is provided with spring groove, is cased with spring in spring groove, and inner oil seal includes support frame two
With the rubber bodies two being positioned at inside support frame two, rubber bodies two overlaps on the mounting shaft, and support frame two bottom and rubber bodies
Two bottom entirety turn up formed described in locating ring.
In above-mentioned a kind of Novel box-type oil sealing, described purchasing ore is provided with some dismounting holes.
Therefore convenient utilization dismounts hole integral disassembly, assembly.
Compared with prior art, this utility model has the advantage that
This utility model good airproof performance, effectively controls inner oil seal and the relative motion space of outer oil seal, convenient installation, has
The dust-proof effect with sealing lubricating oil, can solve the deficiency of combination oil seal in prior art, improves the life using producer
Produce efficiency, reduce cost, can be widely used for the field of sealing technology of combination oil seal.
