Abstract
The utility model relates to an oil seal for the end part of a side reduced disc. The oil seal comprises an outer oil seal, a first inner oil seal and a second inner oil seal which are mutually combined, wherein the outer oil seal adopts a no-spring oil seal which consists of an outer framework and an outer sealing body, the outer framework is L-shaped, the outer sealing body covers the outer side wall and the bottom of the outer framework, and a corrugated structure is arranged in the outer circle position of the outer sealing body covering the outer side wall of the outer framework; the first inner oil seal consists of an inner framework and an inner sealing body, convex corrugation is arranged at an inner hole of the inner sealing body, a plurality of sealing lips are arranged on the inner sealing body, and are respectively propped against the inner side wall of the outer framework of the outer oil seal. The oil seal adopts the combined form and can be mounted at one step, and the oil seal can be mounted conveniently and fast; by increasing the number and different forms of dust prevention lips, impurities outside the oil seal can be effectively prevented from entering the oil seal, the dust prevention efficiency is improved, the reliability is improved, the service life is prolonged, and the maintenance cost is greatly reduced.
Description
Technical field:
The utility model relates to a kind of Sealing, relates 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 in the time of 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 multiple 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.
Model utility content:
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, and 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 utility model 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 formed by outer skeleton and external sealed body 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 made up 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 multiple 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, what seal and spring formed has 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 utility model has the advantage of: Jian Pan end, limit of the present utility model oil sealing is combining form, once mounting is convenient and swift; The impurity such as chip, muddy water, dust that can effectively block oil sealing outside by increasing the quantity of dust excluder lips and the multi-form dust excluder lips of multiple tracks enters oil sealing inside, dustproof effect, reliability and working life are improved, greatly reduce maintenance cost, when oil sealing combination, between each dust excluder lips, be coated with lubricating grease, dry grinding while preventing oil sealing work, causes rubber body wearing and tearing, ensures the seal action of dust excluder lips.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Shown in Figure 1, Jian Pan end, limit of the present utility model 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 formed by outer skeleton 11 and external sealed body 12 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 made up 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 multiple sealing lips 321, described sealing lip 321 leans respectively on outer skeleton 11 madial walls of outer oil seal 1, strengthens dust reduction capability.
