Abstract
The utility model provides a modular refluxing oil seal, including skeleton, rubber oil seal attached to the skeleton and Teflon sealing lip with a spiral oil drive back thread, characterized in that: the orbicular fringe of said Teflon sealing, together with rubber oil seal, joint with the skeleton through vulcanization, and a convex stage is set on the inner side of the skeleton, which is close to the fringe of the convex Teflon sealing lip. The orbicular inner fringe of said Teflon sealing is trumpet-shaped, with spiral oil drive back threads on both sides of which, making the skeleton and Teflon gasket joint more steadily with no checking to leak oil, and improving the abrasive resistance , hermeticity and service life of the oil seal.
Description
Technical field
The utility model belongs to Sealing, is mainly used in the combination seal of engine revolution axle, is a kind of combined type backflow oil sealing specifically.
Background technique
Existing backflow oil sealing adopts has the teflon plate of spiral oil return line, and general the folder with two skeletons pasted teflon plate, snaps together; Also has plenty of cold bonding teflon plate on skeleton.Skeleton folder subsides technology is simple, but stability in use is poor, uses a period of time, and skeleton combines with teflon plate and easily produces distortion, and the formation slit will leakage of oil in the using process.Cold bonding teflon plate on the skeleton, skeleton are metallic material, with the teflon plate different in kind, use the cold bonding mode, and adhesive fastness is not enough, and the time has been grown easily and cracked, also can leakage of oil in the using process.How a kind of backflow oil sealing that improves structure is provided, and skeleton combines firmly with teflon plate, is difficult for cracking and produces leakage of oil, and this has become the technical task that presses for solution at present.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, and a kind of combined type backflow oil sealing is provided, and skeleton combines close and firm with teflon plate, is not easy to crack.
The purpose of this utility model is achieved by the following technical solution: a kind of combined type backflow oil sealing, comprise skeleton, attached to rubber oil sea on the skeleton and have the teflon seal lip of spiral oil return line, it is characterized in that: described teflon seal lip ring-type outer edge and rubber oil sea are connected as a single entity by sulfuration and skeleton, the skeleton inner side surface is provided with boss, and boss is pressed close to teflon seal lip outer edge.
Along being bell mouth shape, bell mouth shape interior all has spiral oil return line along the two sides in the ring-type of described teflon seal lip.
The dust excluder lips that is connected as a single entity with rubber oil sea is arranged along the position in the described skeleton.
The utility model compared with prior art has the following advantages and good effect:
1, the utility model teflon seal lip ring-type outer edge and rubber oil sea are connected as a single entity by sulfuration and skeleton, and the skeleton inner side surface is provided with boss, and boss is pressed close to teflon seal lip outer edge.It is more firm that skeleton is combined with teflon plate, is difficult for cracking and produces leakage of oil.
2, the utility model adopts the teflon seal lip, and its bell mouth shape interior all has spiral oil return line, wear resistance, sealing and the working life of having improved oil sealing along the two sides.
3, the utility model also is provided with dust excluder lips, has improved the oil sealing anti-dust performance, and can prolong the working life of oil sealing.
Description of drawings
Fig. 1 is the sectional drawing along axis of the utility model combined type backflow oil sealing;
Fig. 2 is the partial enlarged drawing of I part among the utility model Fig. 1.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment:
Referring to Fig. 1, Fig. 2, a kind of embodiment of combined type backflow oil sealing comprises skeleton 2, attached to rubber oil sea 1 on the skeleton 2 and have the teflon seal lip 4 of spiral oil return line.
Teflon seal lip 4 ring-type outer edges and rubber oil sea 1 are connected as a single entity by sulfuration and skeleton 2, and skeleton 2 inner side surfaces are provided with boss 3, and boss 3 is pressed close to teflon seal lip 4 outer edges.Along being bell mouth shape, bell mouth shape interior all has spiral oil return line along the two sides in the ring-type of teflon seal lip 4.
The dust excluder lips 5 that is connected as a single entity with rubber oil sea 1 is arranged along the position in the skeleton 2.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
Claims (3)
1, a kind of combined type backflow oil sealing, comprise skeleton, attached to rubber oil sea on the skeleton and have the teflon seal lip of spiral oil return line, it is characterized in that: described teflon seal lip ring-type outer edge and rubber oil sea are connected as a single entity by sulfuration and skeleton, the skeleton inner side surface is provided with boss, and boss is pressed close to teflon seal lip outer edge.
2,, it is characterized in that in the ring-type of described teflon seal lip that along being bell mouth shape bell mouth shape interior all has spiral oil return line along the two sides according to the described combined type backflow of claim 1 oil sealing.
