Description
Technical field
The utility model is related to a kind of Novel rotary sealing ring, especially a kind of to be applied to gear-box, transmission shaft, machinery
Equipment axle rotating seal ring, belongs to oil sealing field.
Background technology
Outside framework oil seal is because its is simple in construction, effect significantly, safeguard change it is convenient and be widely used in machinery, chemical industry, etc. respectively
Each industry of row, existing outside framework oil seal includes skeleton, and the side of skeleton is connected with waist and lip, and lip, which is provided with, encloses spring, skeleton
Opposite side be connected with dust excluder lips, the thickness of dust excluder lips everywhere is roughly equal, and its end and axle gentle touchdown, for stopping ash
Dirt enters, though the outside framework oil seal of this structure can play good sealing function, when axle bias occurs now for various reasons
As and when beating, lip will be carried out pulling drawings, cause lip to lose and justify, and larger gap is formed between axle, this is straight
Connect and cause dust or oil to enter by gap between lip and axle and cause heavy wear to lip, imitate the sealing of outside framework oil seal
The decline of fruit and the service life for having a strong impact on outside framework oil seal, accordingly, it would be desirable to further improve.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect there is provided a kind of Novel rotary sealing ring, passes through
Screw thread, which converges oily line, allows oily non-leakage, fluid partitioning completely, reaches the effect of energy-conserving and environment-protective, effectively can solve in background technology
Problem.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of Novel rotary sealing ring, including sealing ring main body, high-carbon steel wire spring and cold rolling steel skeleton, the sealing ring
The cylindrical front end of main body is oriented to provided with lead angle, and the cylindrical rear portion of sealing ring main body is provided with ring shaped thread, and the cold rolling steel skeleton is set
In sealing ring body lumen, and the cold rolling steel skeleton side is provided with body of rubber, and the sealing ring bottom part body side is provided with
Dirt lip, the dirt lip side is provided with lip end provided with sealed lip and the oily line of screw thread remittance, the sealed lip bottom,
The sealed lip is provided with spring groove, and the high-carbon steel wire spring is located at spring groove inner chamber.
Furthermore, the lead angle, which is oriented to, is less than ring shaped thread size.
Furthermore, the ring shaped thread is many outpost of the tax office linear contact lays.
The utility model beneficial effect：Should be applied to gear-box, transmission shaft, plant equipment axle rotating seal ring in assembling
During play precise positioning effect, it is convenient to install, be unlikely to deform, rear portion ring shaped thread belongs to many outpost of the tax office linear contact lays, seal
Better, oil drive back thread of being extruded during rotary shaft rotation, spiral oil return line can make in oil storage tank in oil meeting auto-returned seal case,
The effect for saving oil and environmental protection is reached, oil seepage in rotating operation is solved, the phenomenon for having prevented oil leak occurs.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and constitutes a part for specification, with this practicality
New embodiment is used to explain the utility model together, does not constitute to limitation of the present utility model.
Fig. 1 is a kind of Novel rotary sealing ring sectional view of the utility model.
Fig. 2 is a kind of Novel rotary sealing ring front section view of the utility model.
Label in figure：1st, sealing ring main body；2nd, lead angle is oriented to；3rd, ring shaped thread；4th, body of rubber；5th, dirt lip；6、

Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As Figure 1-Figure 2, a kind of Novel rotary sealing ring, including sealing ring main body 1, high-carbon steel wire spring 8 with it is cold rolling
Steel skeleton 9, the cylindrical front end of the sealing ring main body 1 is oriented to 2 provided with lead angle, and the cylindrical rear portion of the sealing ring main body 1 is provided with ring-type
Screw thread 3, the lead angle is oriented to 2 and is less than the size of ring shaped thread 3, forms taper and installs, precise positioning is played during assembling
Effect, convenient to install, rear portion ring shaped thread belongs to many outpost of the tax office linear contact lays, and more preferably, the cold rolling steel skeleton 9 is located at close for sealing effectiveness
The inner chamber of seal main body 1, and the side of cold rolling steel skeleton 3 is provided with body of rubber 4, never deforms, the bottom of sealing ring main body 1
Side is provided with dirt lip 5, and it is assembled in the side of dirt lip 5 provided with sealed lip 6 and the oily line 7 of screw thread remittance in first time
The preceding micro machinery oil of storage, plays lubrication when starting first time, cools down, reduce coefficient of friction, it is to avoid dry friction, prevent hot burning
Erosion and pernicious abrasion, in normal operation after startup, oil drive back thread of being extruded during rotary shaft rotation, spiral oil return line can make oil storage tank
Interior oil can reach the effect for saving oil and environmental protection in auto-returned seal case, and the bottom of sealed lip 6 is provided with lip end,
The sealed lip 6 is provided with spring groove, and the high-carbon steel wire spring 8 is located at spring groove inner chamber, and wire spring is received automatically always
Contracting, aids in main lip to be fitted close with axle, fluid partitioning, reaches the effect of energy-conserving and environment-protective, and this practicality solves oil in rotating operation
Seepage, can allow oily completely non-leakage.
It is above the utility model preferably embodiment, the utility model those skilled in the art can also be to upper
State embodiment to be changed and changed, therefore, the utility model is not limited to above-mentioned embodiment, every ability
Any conspicuously improved, replacement or modification that field technique personnel are made on the basis of the utility model belong to this practicality
New protection domain.
