Abstract
The invention relates to an oil seal for the end portion of a wheel redactor plate. The oil seal comprises an outer oil seal body, a first inner oil seal body and a second inner oil seal body, wherein the outer oil seal body, the first inner oil seal body and the second inner oil seal body are mutually combined. The outer oil seal body is a springless oil seal body composed of an outer framework and an outer seal body, the outer framework is L-typed, the outer seal body wraps the outer side wall and the bottom of the outer framework, and the outer circle portion of the outer seal body wrapping the outer side wall of the outer framework is provided with a corrugated structure. The first inner oil seal body is composed of an inner framework and an inner seal body, an inner hole of the inner seal body is provided with convex crinkles, the inner seal body is provided with a plurality of sealing lips, and the sealing lips abut against the inner side wall of the outer framework of the outer oil seal body. The oil seal is of a combined mode, can be installed once, and is convenient and quick to use. By means of increasing of the number of dustproof lips and multiple dustproof lips of different modes, impurities outside the oil seal can be effectively prevented from entering the oil seal, the dustproof effect and reliability are improved, service life is prolonged, and maintenance cost is greatly reduced.
Description
Technical field:
The present invention relates to a kind of Sealing, relate in particular to Jian Pan end, a kind of limit oil sealing.
Background technique:
At present, the Jian Pan position, limit of 120 horsepowers of tractors of working under rugged environment is when sealing, people often adopt two and above oil sealing to carry out combination seal, to reach good sealing effect, should there is the lubricant medium in main lip seal cavity, Leakage prevention, there is again dust excluder lips to block the chip of oil sealing outside, muddy water, other impurity such as dust, prevent that impurity etc. from entering from the dust excluder lips side of oil sealing, thereby enter main lip and cause oil sealing leakage of oil, existing combination oil seal is to adopt a plurality of common oil sealings to carry out combination seal, if closely combine, end-face friction resistance is larger, and thermal diffusivity is bad, affect the working life of oil sealing, if have gap after combination, the secondary lip of oil sealing place decrement is little does not reach desirable envelope dirt effect, can cause oil sealing play simultaneously, causes leakage of oil.And the dust excluder lips negligible amounts of each oil sealing, being difficult to improve dustproof effect, dust-proof effect need to improve again.
Summary of the invention:
The object of the invention is to overcome deficiency of the prior art, provide a kind of rational in infrastructure, the impurity that can effectively block oil sealing outside enters Jian Pan end, the limit oil sealing of oil sealing inside.
In order to achieve the above object, the present invention adopts following technological scheme:
Jian Pan end, limit oil sealing, comprises outer oil seal, the first inner oil seal and second inner oil seal of mutual combination, described outer oil seal adopt by outer skeleton and external sealed body, formed without spring oil sealing, described outer skeleton is L-type, described external sealed body is coated on outer side wall and the bottom of outer skeleton, the cylindrical place that is coated on the external sealed body of outer skeleton outer side wall is provided with ripple struction, described the first inner oil seal is comprised of inner frame and interior seal, the endoporus of described interior seal is provided with the ripple of convex, facilitates the installation of oil sealing and axle, and described interior seal is provided with a plurality of sealing lips, described sealing lip leans respectively on the outer skeleton madial wall of outer oil seal, strengthens dust reduction capability, described the second inner oil seal adopts by skeleton, seal and spring form spring oil sealing, the part of described seal envelopes the back of skeleton, the part of coated skeleton is not provided with primary seal lip and two secondary sealing lips, the opposing side of described primary seal lip is provided with groove, in groove, be provided with spring, the primary seal lip of described the second inner oil seal and two secondary sealing lips all lean on the inner frame of the first inner oil seal, the described seal that envelopes skeleton back portion fits tightly the madial wall on skeleton top outside, the termination of the outer skeleton upper end portion of described outer oil seal is arranged to step-like, after holding limit by combination, be pressed against on the skeleton of the second inner oil seal.
Further, the seal of described outer oil seal, the second inner oil seal and the first inner oil seal all adopts quality of rubber materials.
Further, the skeleton of described outer oil seal, the second inner oil seal and the first inner oil seal all adopts carbon steel.
The invention has the advantages that: Jian Pan end, limit of the present invention is combining form with oil sealing, once mounting is convenient and swift; By increasing the impurity such as the quantity of dust excluder lips and chip that the multi-form dust excluder lips of multiple tracks can effectively be blocked oil sealing outside, muddy water, dust, enter oil sealing inside, dustproof effect, reliability and working life have been improved, greatly reduce maintenance cost, during oil sealing combination, in each dust excluder lips, ask painting lubricating grease, dry grinding while preventing oil sealing work, causes rubber body wearing and tearing, guarantees the seal action of dust excluder lips.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Shown in Figure 1, Jian Pan end, limit of the present invention oil sealing, comprises outer oil seal 1, the first inner oil seal 3 and second inner oil seal 2 of mutual combination;
Described outer oil seal 1 adopt by outer skeleton 11 and external sealed body 12, formed without spring oil sealing, described outer skeleton 11 is L-type, described external sealed body 12 is coated on outer side wall and the bottom of outer skeleton 11, the cylindrical place that is coated on the external sealed body 12 of outer skeleton 11 outer side walls is provided with ripple struction 121, can make like this seal reduce resistance is installed, facilitate the use of oil sealing to install, improve oil sealing working life.
Described the first inner oil seal 3 is comprised of inner frame 31 and interior seal 32, the endoporus of described interior seal 32 is provided with the ripple of convex, facilitate the installation of oil sealing and axle, described interior seal 32 is provided with a plurality of sealing lips 321, described sealing lip 321 leans respectively on outer skeleton 11 madial walls of outer oil seal 1, strengthens dust reduction capability.
Described the second inner oil seal 2 adopts by skeleton 21, seal 22 and spring 23 forms spring oil sealing, the part of described seal 22 envelopes the back of skeleton 21, the part of coated skeleton 21 is not provided with primary seal lip 221 and two secondary sealing lips 222, the opposing side of described primary seal lip 221 is provided with groove, in groove, be provided with spring 23, the primary seal lip 221 of described the second inner oil seal 2 and two secondary sealing lips 222 all lean on the inner frame 31 of the first inner oil seal 3, the described seal 22 that envelopes skeleton 21 back portions fits tightly the madial wall on skeleton 11 tops outside, the termination 4 of outer skeleton 11 upper end portions of described outer oil seal 1 is arranged to step-like, after holding limit by combination, be pressed against on the skeleton 21 of the second inner oil seal 2.During oil sealing combination, need to ask painting lubricating grease in each dust excluder lips, dry grinding while preventing oil sealing work, causes rubber body wearing and tearing, guarantees the seal action of dust excluder lips.
