Abstract
The utility model discloses a reverse-edge oil seal, which comprises an oil seal main body, and is characterized in that: a plurality of screw hole positions are circumferentially arranged at the edge of the oil seal main body; the oil seal main body comprises an outer layer of metal frame and an inner layer of silicon rubber liner, the outer layer of metal frame is Z-shaped, the edge of the upper part of the silicon rubber liner is inwards folded and wraps the upper part of the outer layer of metal frame, a caulking groove is arranged at the lower part of the silicon rubber liner, and the bottom of the outer layer of metal frame is embedded in the caulking groove. The reverse-edge oil seal has a simple and stable structure, a good sealing property and a good popularization value.
Description
Technical field
The utility model relates to the seal arrangement technical field, relates to a kind of oil seal structure in particular.
Background technique
Oil sealing is to be used for the mechanical component of oil sealing, and it isolates the parts that need in the transmission part to lubricate and the parts of exerting oneself, and is unlikely to allow oil seepage.Can be divided into various ways and different calls from seal action, characteristics, structure type, working state and the sealing mechanism etc. of oil sealing, but traditionally generally with rotary shaft lip seal on oil sealing, static seal and motive sealing (general to-and-fro motion) with Sealing Sealing.Oil sealing generally is divided into unitary and packaging, and packaging is that skeleton and lip material can independent assortments, generally is used for special oil sealing.The position that in every operating body case lubricating oil is arranged and be connected with the outside all needs oil sealing, and some is a rubber, and some is a metal, and majority is a reinforcing bar rubber, and what anti-limit oil sealing adopted is the reinforcing bar rubber structure, generally has shortcomings such as installing and locating difficulty.
The model utility content
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, good seal performance, and, firm anti-limit oil sealing is installed.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of anti-limit oil sealing, and the oil sealing main body is characterized in that, described oil sealing body rim circumferentially is provided with a plurality of screw holes position.
As further specifying of such scheme, described oil sealing main body comprises outer layer metal skeleton and internal layer silicone rubber liner, the outer layer metal skeleton is Z-shaped, the inside turnup of the top edge of silicone rubber liner also is wrapped in the top of outer layer metal skeleton, the downside of silicone rubber liner is provided with caulking groove, and the bottom of outer layer metal skeleton is flush-mounted in this caulking groove.
The arranged outside of described a plurality of screw holes position has convex tendon, and convex tendon is around in outside the one-sided edge of each screw hole.
The lip arranged outside of described oil sealing main body has annular groove, and assembly has spring ring in the annular groove.
The lip inboard of described oil sealing main body is provided with oil drive back thread, and this oil drive back thread is rearranged by some the convex tendons that are obliquely installed.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model is provided with a plurality of screw holes position at the edge of oil sealing main body, the screw hole position is locked with screw, and in operation, oil sealing can not be offset, sound construction.

Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: 1, oil sealing main body 1-1, metal frame 1-2, elastometric lining 2, screw hole position 3, convex tendon 4, annular groove
Embodiment
As shown in Figure 1, a kind of anti-limit of the utility model oil sealing, oil sealing main body 1, oil sealing main body 1 edge circumferentially is provided with a plurality of screw holes position 2, the oil sealing main body comprises outer layer metal skeleton 1-1 and internal layer silicone rubber liner 1-2, and the outer layer metal skeleton is Z-shaped, and the inside turnup of the top edge of silicone rubber liner also is wrapped in the top of outer layer metal skeleton, the downside of silicone rubber liner is provided with caulking groove, and the bottom of outer layer metal skeleton is flush-mounted in this caulking groove.The arranged outside of a plurality of screw holes position has convex tendon 3, and convex tendon 3 is around in outside the one-sided edge of each screw hole.The lip arranged outside of oil sealing main body has annular groove 4, and assembly has spring ring in the annular groove.The lip inboard of oil sealing main body is provided with oil drive back thread, and this oil drive back thread is rearranged by some the convex tendons that are obliquely installed.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
