Description
Technical field
The utility model is related to one kind for rotation axis seal mechanism, more particularly to a kind of power-equipment rotary shaft
Sealing mechanism.
Background technology
In plant equipment, sealing mechanism is indispensable part, such as internal combustion engine, and rotary shaft is revolved at a high speed in the course of the work
Turn, need oil-sealing sleeve to be sealed on the rotary shaft, existing conventional oil sealing is mainly by rubbery sealed body, skeleton, spring, main lip
And secondary lip is constituted, oil sealing inner ring by the elastic force of spring by main lockjaw admittedly on the rotary shaft, outer ring is uniform by crankcase
Radial forces compression oil sealing outer ring so that oil sealing reaches the effect of sealing, at this structure oil sealing under extreme conditions
When, structure, reliability and durability are difficult to reach the use requirement of engine under particular job environment, still await further
Technology is solved.
Utility model content
In order to solve the above problems, the utility model provides a kind of rotation axis seal mechanism.
The technical solution adopted in the utility model is：A kind of rotation axis seal mechanism, it is characterised in that including rotary shaft, on
Casing, lower box and oil sealing, oil sealing are provided with ring skeleton, inner ring sealing and outer ring sealing, and it is U-shaped that inner ring sealing is provided with section
U-type groove in annular, ring skeleton inner edge are embedded in interior U-type groove, and the both sides of the annular inner rim of interior U-type groove are connected to annular
Left lip and annular right lip, left lip and right lip sealed with rotary shaft contacts side surfaces, and left lip and right lip back are equipped with cannelure,
The O-shaped spring that left lip and right lip are strapped in rotary shaft side is provided with cannelure, and it is outer that outer ring is sealed into the U-shaped annular in section
U-type groove, ring skeleton outer rim are embedded in outer U-type groove, be respectively equipped with and clamp outside outer U-type groove annular on upper box, lower box
The V-groove of edge.
Further, the groove for possessing spacing with rotary shaft side is provided between the left lip and right lip.
When the utility model is used, two main lips of left lip and right lip are fastened on rotary shaft under the constraint of two O-shaped springs,
The dynamics of both sides turn-knob is more balanced, improve sealing property while improving inner ring sealing service life, upper box, lower box
V-groove clamps outer U-type groove outer circular edge, make outer U-type groove outer circular edge deform be fitted in V-groove, realize be reliably connected and
Sealing, can effectively prevent oil sealing from going out.

Specific embodiment
As shown in Figure 1, 2, the rotation axis seal mechanism is provided with rotary shaft 1, upper box 2, nowel to the utility model embodiment
Body 3 and oil sealing, oil sealing are provided with ring skeleton 4, inner ring sealing 5 and outer ring sealing 6, and inner ring sealing and outer ring sealing are rubber material
Matter, inner ring sealing are provided with U-type groove 7 in the U-shaped annular in section, and ring skeleton inner edge is embedded in interior U-type groove, interior U-type groove
The both sides of annular inner rim are connected to the left lip 8 of annular and the right lip 9 of annular, and left lip and right lip are close with rotary shaft contacts side surfaces
Envelope, left lip and right lip back are equipped with cannelure, are provided with the O-shaped bullet that left lip and right lip are strapped in rotary shaft side in cannelure
Spring 10, outer ring are sealed into the outer U-type groove of the U-shaped annular in section, and ring skeleton outer rim is embedded in outer U-type groove, upper box, nowel
The V-groove 11 for clamping outer U-type groove outer circular edge is respectively equipped with body.
When the utility model is used, two main lips of left lip and right lip are fastened on rotary shaft under the constraint of two O-shaped springs,
The dynamics of both sides turn-knob is more balanced, improve sealing property while improving inner ring sealing service life, upper box, lower box
V-groove clamps outer U-type groove outer circular edge, make outer U-type groove outer circular edge deform be fitted in V-groove, realize be reliably connected and
Sealing, can effectively prevent oil sealing from going out.
The groove for possessing spacing with rotary shaft side can be also set during enforcement between left lip and right lip and reduces friction.
The utility model preferred embodiment is only in sum, and all equivalent modifications that is done according to the application and prior art add
Plus it is accordingly to be regarded as the utility model technology category.
