Abstract
The utility model relates to a sealing member, and particularly an anti-slush oil seal with an oil seal seat. The anti-slush oil seal comprises an anti-slush oil seal body and the oil seal seat which is in interference fit with a rotating shaft. The anti-slush oil seal body is arranged outside the annular oil seal seat, wherein the inner surface of a seat hole of the oil seal seat is provided with rubber. The anti-slush oil seal with the oil seal seat provided by the utility model realizes high slush sealing effect and prolongs service life of a wheel.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of anti-muddy water oil sealing with oil sealing base.
Background technique
Rice field reaper gathers in work in rice field, and wheel position is usually in slurry environment, need to guarantee that sealing slurry does not enter wheel inside, prevents the leakage of internal bearings lubricating grease simultaneously, makes wheel rotary work normally.Existing sealing configuration comprises anti-muddy water oil sealing, oil sealing base and O shape circle, O shape circle is arranged in the groove on axle, and oil sealing base extruding O type circle is also tightly placed in spin axis, and oil sealing base, O shape circle and oil sealing base fixture are combined, follow axle and rotate together, form the sealing at axle place.Seat hole place installed muddy water-resistant oil seal, is positioned oil sealing by stop ring, and oil sealing base is located by bearing inner race, and bearing inner race is located by bearing inner race fixed cover.In actual application, find that sealing structure exists following defect:
(1) while oil sealing base being installed, because needs push O shape circle, O shape circle is usually twisted distortion or squeezes off, and causes seal failure;
(2) anti-muddy water oil sealing coordinates with oil sealing base, and by main lip and the secondary lip seal mud of twice of oil sealing, effect is undesirable, and muddy water is easy to enter bearing inside.
Model utility content
The purpose of this utility model is to overcome the above-mentioned defect that existing oil sealing exists, and has proposed a kind of anti-muddy water oil sealing with oil sealing base, and its sealing slurry effective extended working life of wheel.
The utility model is to adopt following technological scheme to realize: a kind of anti-muddy water oil sealing with oil sealing base, comprise anti-muddy water oil sealing and be the oil sealing base of interference fit with running shaft, anti-muddy water oil sealing is positioned at the annular outboard of oil sealing base, and wherein, the internal surface in described oil sealing base seat hole is provided with rubber.
In the utility model, between described rubber and the inwall in oil sealing base seat hole, can be connected by bonding way.
Described anti-muddy water oil sealing is made up of outer oil seal and inner oil seal, wherein outer oil seal comprises outer oil seal skeleton, outer oil seal spring, primary seal lip and dust excluder lips, dust excluder lips comprises the axial dust excluder lips of multiple tracks and end face dust excluder lips, inner oil seal comprises inner oil seal skeleton and rubber body, and the axial dust excluder lips of outer oil seal and the lip of end face dust excluder lips are all interference fit with inner oil seal skeleton.
Described dust excluder lips comprises at least one axial dust excluder lips; Described dust excluder lips comprises at least one end face dust excluder lips.
The beneficial effects of the utility model are:
(1) oil sealing base and running shaft interference fit, and seal by endoporus adhesive rubber, endoporus adhesive rubber there will not be the phenomenon that distorts, squeezes off, and has improved the sealing effect of oil sealing, is convenient to the installation of oil sealing simultaneously;
(2) anti-muddy water oil sealing adopts mazy sealing configuration, has improved the sealing slurry effect of anti-muddy water oil sealing, has extended the working life of rice field reaper wheel.
Accompanying drawing explanation
Fig. 1 is the assembly structure schematic diagram of existing anti-muddy water oil sealing;
Fig. 2 is assembly structure schematic diagram of the present utility model;
Fig. 3 is half sectional view of the present utility model.
In figure: 1 anti-muddy water oil sealing; 2 stop rings; 3 bearing outer rings; 4 bearing inner races; 5 bearing inner race fixed covers; 6 running shafts; 7 oil sealing base fixed blocks; 8 oil sealing bases; 9 outer oil seals; 901 outer oil seal skeletons; 902 outer oil seal springs; 903 primary seal lips; 904 axial dust excluder lips; 905 end face dust excluder lips; 10 inner oil seals; 1001 inner oil seal skeletons; 11 rubber.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 2, anti-muddy water oil sealing 1 is positioned at the annular outboard of oil sealing base 8, and the internal surface in 8 holes of oil sealing base is provided with rubber 11, and rubber 11 is bonding with the inwall in oil sealing base seat hole.Oil sealing base 8 and running shaft 6 interference fit, seal by endoporus adhesive rubber 11, and endoporus adhesive rubber there will not be the phenomenon that distorts, squeezes off, and installs more convenient simultaneously.The bottom of oil sealing base 8 is provided with oil sealing base fixed block 7.Oil sealing base 8 is located by bearing inner race 4, and bearing inner race 4 is located by bearing inner race fixed cover 5.Anti-muddy water oil sealing 1 is positioned it by stop ring 2.
Anti-muddy water oil sealing 1 is made up of outer oil seal 9 and inner oil seal 10, and wherein outer oil seal 9 comprises outer oil seal skeleton 901, outer oil seal spring 902, primary seal lip 903 and dust excluder lips, and dust excluder lips comprises the axial dust excluder lips 904 of multiple tracks and end face dust excluder lips 905.Inner oil seal 10 comprises inner oil seal skeleton 1001 and rubber body.Outer oil seal spring 902 provides radial force for primary seal lip 903, primary seal lip 903 is fitted tightly on inner oil seal skeleton 1001, thereby make primary seal lip 903 play main seal action, prevent that lubricant oil or grease from leaking, and stop entering of outside muddy water.The axial dust excluder lips 904 of outer oil seal 9 and the lip of end face dust excluder lips 905 are all interference fit with inner oil seal skeleton 1001, form mazy sealing configuration, sealing slurry better effects if.Inner oil seal 6 can rotate relative to outer oil seal 1.
When this oil sealing work, oil sealing base 8 and oil sealing base fixture 7 are combined, and follow running shaft 6 and rotate together, form the sealing at running shaft place by endoporus adhesive rubber 11, seat hole place installed muddy water-resistant oil seal 1.This oil sealing is convenient to install, and sealing slurry is effective, has extended the working life of wheel.
