Abstract
The utility model discloses a kind of engine oil seal, including metallic framework ringwise and rotatory sealing lip, it is characterized in that, the bottom of described metallic framework arranges the support base ring that oriented middle part extends, rotatory sealing lip is arranged on support base ring, rubber layer, rubber layer and rotatory sealing lip heat cure molding is had between rotatory sealing lip and support base ring.This utility model simple in construction, bonding firmly, prevents leakage, and compared to the product of same type, performance is more superior.
Description
Technical field
This utility model relates to engine oil seal technical field, especially relates to a kind of metallic framework and PTFE sulfidization molding
Engine oil seal.
Background technology
At present, the oil seal for crankshaft of engine simple in construction being made up of metallic framework, seal reliable.But difficulty of processing is high, special
It not that PTFE is loaded down with trivial details with metallic framework adhesion technique.When using rubber pressure injection vulcanization to produce, mould structure is complicated, and material damages
Consumption is many, and product qualified rate is the highest.
Summary of the invention
The one that the purpose of this utility model is contemplated to solve the deficiency of prior art and provides is not only simple in structure, and adds
The convenient engine oil seal of work.
This utility model is to use following technical solution to be attained in that a kind of engine oil seal, including in
The metallic framework of annular and rotatory sealing lip, it is characterised in that the bottom of described metallic framework arranges propping up of oriented middle part extension
Support base ring, rotatory sealing lip is arranged on support base ring, at rotatory sealing lip and support and have rubber layer between base ring, rubber layer with
Rotatory sealing lip pressurized heat cure molding.
Further, the top of metallic framework is provided with the flange that outwards bending extends, and flange is provided with caulking gum
Circle, the outer rim of flange is provided with the location chimb being folded upward at, and flange surface is close in the bottom of sealing rubber ring, and sidepiece is close to fixed
Chimb side, position.
Further, the thickness of described rubber layer is at 0.4-0.5mm, it is ensured that rubber is fine and close, bonding is firm, prevents leakage.
One side of described rotatory sealing lip is connected fixing by rubber layer with metallic framework, and another side tilts upward and prolongs
Stretch formation kink.
Further, described rotatory sealing lip is PTFE seal lip, uses the bonding at metallic framework Yu PTFE seal lip
Rubber slurry deployed in topcoating, the dried a thin layer rubber layer that formed, then with PTFE pressurized heat cure molding.
This utility model uses above-mentioned technical solution can reach to provide the benefit that:
This utility model uses the adhesive surface at metallic framework Yu rotatory sealing lip to coat rubber slurry, forms one after drying
Thin layer rubber layer, then with PTFE pressurized heat cure molding, and make rubber layer at 0.4-0.5mm by the spacing control of mould, it is ensured that
Rubber is fine and close, bonding is firm, prevents leakage, and this version operation is simple, and glue consumption is extremely low, seals reliable.

Detailed description of the invention
Below in conjunction with specific embodiment, the technical program is explained in detail.
As Figure 1-Figure 2, this utility model is a kind of engine oil seal, including metallic framework 1 ringwise and rotation
Sealing lip 2, the bottom of metallic framework 1 arranges the support base ring 1-1 that oriented middle part extends, and rotatory sealing lip 2 is arranged on the support end
On ring 1-1, rubber layer 3, rubber layer 3 is had to become with rotatory sealing lip pressurized heat cure between rotatory sealing lip 2 and support base ring
Type.The top of metallic framework 1 is provided with the flange 1-2 that outwards bending extends, and flange is provided with sealing rubber ring 4, flange
Outer rim is provided with the location chimb 1-3 being folded upward at, and flange surface is close in the bottom of sealing rubber ring, and sidepiece is close to position chimb
Side.The thickness of rubber layer is at 0.4-0.5mm, and the present embodiment is 0.4mm, it is ensured that rubber is fine and close, bonding is firm, prevents leakage.
Further, a side of rotatory sealing lip 2 is connected fixing by rubber layer with metallic framework, and another side tilts
Upwardly extend formation kink 2-1.Rotatory sealing lip is PTFE seal lip, uses the bonding at metallic framework Yu PTFE seal lip
Rubber slurry deployed in topcoating, the dried a thin layer rubber layer that formed, then with PTFE pressurized heat cure molding.
This utility model compared with prior art, uses the adhesive surface at metallic framework Yu rotatory sealing lip to coat rubber glue
Slurry, the dried a thin layer rubber layer that formed, then with PTFE pressurized heat cure molding, it is ensured that rubber is fine and close, bonding firmly, anti-stopping leak
Leakage, this version operation is simple, and glue consumption is extremely low, seals reliable.
Above-described is only preferred implementation of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these all belong to
In protection domain of the present utility model.
