Abstract
The utility model relates to a sealing part, in particular to a full immersed oil seal of a crawler-type paddy field harvester. The full immersed oil seal comprises an outer oil seal and an inner oil seal, wherein the outer oil seal and the inner oil seal are combined together to form the oil seal by aid of assembling of a shaft and a seat hole. The full immersed oil seal is characterized in that the outer oil seal is provided with two springless axial anti-dust lips, sealing ribs are designed on a radial end surface of the outer oil seal and are in interference fit with a framework end surface of the inner oil seal, two end surface radial anti-dust lips are disposed on the radial end surface of the outer oil seal, the outer oil seal is provided with a turned edge structure, and an oil storage chamber is formed among the axial anti-dust lips and the end surface radial anti-dust lips of the outer oil seal. The full immersed oil seal of a crawler-type paddy field harvester is provided with a novel muddy water preventive structure integrating axial sealing and end surface radial sealing so that bearings of crawlers of a crawler-type paddy field harvester are fine in sealing property, and is fine in anti-dust and muddy water preventive effects, convenient for repair and maintenance and long in service life.
Description
Technical field
The utility model relates to a kind of seal, and especially a kind of crawler type immerses rice field grain header oil sealing entirely.
Background technology
The grain header collection harvesting of crawler type rice field, threshing, its crawler belt major part is immersed in the muddy water the inside, so require the oil sealing at this position to have well anti-muddy water effect, to prevent that the muddy water in the rice field is immersed in bearing internal sabotage bearing, also to keep the lubricant grease in the bearing not reveal in addition, thereby make bearing keep lubricated fully, but the general anti-dust seal of this position application and the effect of anti-muddy water oil sealing are not very desirable at present, all exist muddy water to immerse the phenomenon of bearing inside, thereby destruction bearing, also cause the lubricant grease in the bearing to reveal easily, make bearing can't keep lubricated fully, quicken the wearing and tearing of bearing, like this, the maintenance of equipment is frequent, and service life is short, damages easily.
The utility model content
The purpose of this utility model is to have proposed a kind of crawler type and immerses rice field grain header oil sealing entirely, this oil sealing has the new anti-muddy water structure of having gathered axial seal and end face radial seal, it makes that the tracks of harvester position bearing seal of crawler type rice field is good, prevent the effective of dust and anti-muddy water, be convenient to maintenance, long service life.
The technical scheme that the utility model adopted is:
A kind of crawler type immerses rice field grain header oil sealing entirely, comprises outer oil seal and inner oil seal, outer oil seal and inner oil seal through axle and the seat hole assembling and combine the formation oil sealing, it is characterized in that outer oil seal is provided with two no spring formula direction of principal axis dust excluder lips.
Described crawler type immerses rice field grain header oil sealing entirely, and the radial end face place of its outer oil seal has designed sealed muscle, and the skeleton end face of sealed muscle and inner oil seal is an interference fit.
Described crawler type immerses rice field grain header oil sealing entirely, and the radial end face place of its outer oil seal is provided with twice end face direction dust excluder lips.
Described crawler type immerses rice field grain header oil sealing entirely, and its outer oil seal is provided with turnup structure.
Described crawler type immerses rice field grain header oil sealing entirely, and axial dust excluder lips of its outer oil seal and end face radially form accumulator between the dust excluder lips.
Like this in when work, outer oil seal and inner oil seal are combined the formation oil sealing through the assembling in axle and seat hole, play sealing function; Two no spring formula direction of principal axis dust excluder lips that are provided with on the outer oil seal can reduce rotation torque, reduce design cost; The radial end face place of outer oil seal has designed sealed muscle, can increase and prevent that tentatively bulky grain muddy water from entering the effect of oil sealing inside, and the skeleton end face of sealed muscle and inner oil seal is an interference fit, can better stop bulky grain silt to enter oil sealing inside, strengthens preliminary sealing effectiveness; The twice end face direction dust excluder lips that the radial end face place of outer oil seal is provided with can be pursued the dust that enters oil sealing inside on a small quantity and stopped, thereby fully keeps its sealing property; The turnup structure that outer oil seal is provided with, it can play the effect of location when installing in the seat hole; Axial dust excluder lips of outer oil seal and end face radially form accumulator between the dust excluder lips, can fill lubricant grease inside, and the oil sealing that makes keeps sufficient lubrication.
Crawler type of the present utility model immerses rice field grain header oil sealing entirely, have the new anti-muddy water structure of having gathered axial seal and end face radial seal, it makes that the tracks of harvester position bearing seal of crawler type rice field is good, prevents the effective of dust and anti-muddy water, be convenient to maintenance, long service life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is that crawler type immerses rice field grain header oil sealing scheme of installation entirely.
Among the figure, 1 is outer oil seal, and 2 is the outer oil seal skeleton, and 3 is inner oil seal, and 4 is the inner oil seal skeleton, and 5 is end face direction dust excluder lips, and 6 is the direction of principal axis dust excluder lips, and 7 is end face direction sealed muscle, and 8 is the seat hole, and 9 is axle, and 10 is flange.
Embodiment
Embodiment
As shown in Figure 1, a kind of crawler type immerses rice field grain header oil sealing entirely, comprise outer oil seal 1 and inner oil seal 3, outer oil seal 1 and inner oil seal 3 are combined the formation oil sealing through the assembling in axle 9 and seat hole 8, it is characterized in that outer oil seal 1 is provided with two no spring formula direction of principal axis dust excluder lips 6; The radially section part of outer oil seal 1 has designed sealed muscle 7, and skeleton 4 sections of sealed muscle 7 and inner oil seal 3 are interference fit; The radial end face place of outer oil seal 1 is provided with twice end face direction dust excluder lips 5; Outer oil seal 1 is provided with flange 10 structures; Outer oil seal 1 axial dust excluder lips 6 and end face radially form accumulator between the dust excluder lips 5.
Like this in when work, outer oil seal 1 and inner oil seal 3 are combined the formation oil sealing through the assembling in axle 9 and seat hole 8, play sealing function; Two no spring formula direction of principal axis dust excluder lips 6 that are provided with on the outer oil seal 1 can reduce rotation torque, reduce design cost; The radial end face place of outer oil seal 1 has designed sealed muscle 7, can increase and prevent that tentatively bulky grain muddy water from entering the effect of oil sealing inside, and sealed muscle 7 is an interference fit with skeleton 4 end faces of inner oil seal 3, can better stop bulky grain silt to enter oil sealing inside, strengthens preliminary sealing effectiveness; The twice end face direction dust excluder lips 5 that the radial end face place of outer oil seal 1 is provided with can be pursued the dust that enters oil sealing inside on a small quantity and stopped, thereby fully keeps its sealing property; Flange 10 structures that outer oil seal 1 is provided with, it can play the effect of location when installing in seat hole 8; Outer oil seal 1 axial dust excluder lips 6 and end face radially form accumulator between the dust excluder lips 5, can fill lubricant grease inside, and the oil sealing that makes keeps sufficient lubrication.
