Abstract
The utility model relates to an integrated hub bracket oil seal. The integrated hub bracket oil seal is subjected to vulcanization molding by a metal bracket and a rubber body via a mould; after the integrated hub bracket oil seal is molded, a main lip mouth, an auxiliary lip mouth and an auxiliary lip boss are generated by the rubber body; the outer side of the main lip mouth is provided with a steel wire spring; and the main lip mouth and a working shaft are in interference fit. On the basis of the structure of the traditional combined bracket oil seal, the two combined parts are integrated into one integrated part; the metal bracket is combined with a metal skeleton in the oil seal into a whole; the dimensional precision and the cooperation precision of the metal bracket are guaranteed by integrated stamping molding; the traditional working procedure of riveting is omitted; the metal bracket is put into the vulcanization mould to be directly subjected to vulcanization bonding molding with rubber so as to serve as one part to be integrally used; the oil seal lip mouth concentricity after installation is improved, the production working procedure is simplified, the production efficiency is improved, and the enterprise production cost is lowered.
Description
Technical field
The utility model relates to a kind of integral type wheel hub holder oil sealing.
Background technique
In present Combined hub support oil seal structure, what adopt is that the mode of separated and assembled is produced, it at first is processing metal support (03), again the oil sealing riveting that contains metal frame (02) and rubber body (01) of sulfidization molding is installed in the Steel Support, form knockdown support oil sealing, though changed the support assembly structure of traditional approach, improved concentricity, but this structure its technological requirement in actual production is higher, if board or other instrument break down, the product concentricity of producing can seriously be affected, and is difficult to management and control, the difficulty of fixing a breakdown, cause manufacturing efficiency to reduce, so that the performance of enterprises is impaired, there is greater risk, product structure is as shown in Figure 1.
Summary of the invention
In order to solve above technical problem, the purpose of this utility model is to provide a kind of higher concentricity, reduces production risk, simplifies production process, the integral type of enhancing productivity wheel hub holder oil sealing.
The utility model passes through the mould sulfidization molding by Steel Support and rubber body, and after the moulding, rubber body generates main lip and secondary lip, and the outside at main lip is provided with wire spring, and described main lip and working shaft interference are fitted.
The utility model above secondary lip, is provided with secondary lip boss.
The utility model on Steel Support, is provided with mounting hole and fixed hole, and mounting hole is the plane assembling, and fixed hole is vertical assembling, and its mutual central hole size precision is controlled at 0.02～0.05mm.
The utility model is with original two component (Steel Supports; The oil sealing that contains metal frame and rubber body) combination is made as a whole total member and is controlled, rubber body and Steel Support are directly produced by the mould sulfidization molding, so both guaranteed raising product lip concentricity, reduced again the risk that breaks down aborning, and size is easier to management and control; Simultaneously, two component parts as a total member production, had both been saved the riveting dress operation of producing, again so that improving productivity obtains better productivity effect.
The utility model, on the architecture basics of original modular support oil sealing, two parts of combination are integrated into an integral type part, metal frame in Steel Support and the oil sealing is integrally combined, use integration stamped moldedly, guaranteed dimensional accuracy and the quality of fit of Steel Support, cancel original riveting dress operation, Steel Support is put in the vulcanization die directly adhesion-molded with the vulcanization of rubber, as the whole use of a part.
The utility model is not only guaranteed the stability that concentricity is controlled, conformity of production, and simplify production process, and save raw material, reduce cost, reduce the production operation risk, greatly improved efficient, have the characteristics such as efficient, safe, easy-to-use.
Description of drawings
Fig. 1 is the structural representation of existing Combined hub support oil sealing; Fig. 2 is structure (dissecing) schematic diagram of the present embodiment; Fig. 3 is the plan structure schematic diagram of the present embodiment; The use erection drawing of Fig. 4 the present embodiment.
Among the figure, 01, the rubber body of existing Combined hub support oil sealing; 02, the oil tight skeleton of existing Combined hub support oil sealing; 03, the Steel Support of existing Combined hub support oil sealing; 1, rubber body; 2, wire spring; 3, Steel Support; 4, mounting hole; 5, fixed hole; 6, secondary lip; 7, secondary lip boss; 8, main lip; 9, machine oil; 10, working shaft.
Embodiment
With reference to Fig. 2, integral type wheel hub holder oil sealing is made of three large agent structures, and is basic identical with the structure of traditional oil sealing, and be respectively: 1 is rubber body; 2 is wire spring; 3 is Steel Support.Steel Support 3 and rubber body 1 are by behind the mould sulfidization molding, and rubber body 1 generates main lip 8, secondary lip 6 and secondary lip boss 7, and described main lip 8 is fitted with working shaft 10 interference.Be optimized by the structure of press tool with Steel Support 3, adjust the space with rubber body 1 sulfuration adhesion, after metal frame 3 impact briquettings, directly and rubber body 1 sulfuration adhesion moulding in vulcanization die, again wire spring 2 is assembled on the lip position at last, is integrally formed formula wheel hub holder oil sealing.
With reference to Fig. 3, this integral type wheel hub holder oil sealing is provided with mounting hole 4 and fixed hole 5 at Steel Support 3, and mounting hole 4 is the plane assembling, and fixed hole 5 is vertical assembling, its mutual central hole size precision is controlled at the scope of 0.02～0.05mm, guaranteed the concentricity after its assembling.
With reference to Fig. 4, this integral type wheel hub holder oil sealing is by after assembling, and main lip 8 is fitted with working shaft 10 interference, during work, sealing machine oil 9 forms sealing system, secondary lip 6 and working shaft 10 micro-Interference contacts, reach dust-proof effect, secondary lip boss 7 is one slow pressures, and the structure of protective action is when directly being clashed into by external force, secondary lip boss 7 can rebound in decompression, so that sealing system of the present utility model is not fragile.
