Above-mentioned bearing is mainly used on the power-operated mower that working environment is the most severe, its working condition is: rotating speed 3600r/min, maximum operating temperature 60 DEG C, during live load, centrifugal force is big, and wherein sealing ring of bearing is directly and water and mud contacts, or a sealing ring of bearing is immersed in mud and water.Due to water or the erosion of mud, the sealing property frequently resulting in this bearing lost efficacy, and had a strong impact on the working life of bearing.By analysis, the predominantly outside silt of the performance that above-mentioned bearing seal was lost efficacy, rainwater enter Bearing inner or Bearing inner lubricating grease leakage out, and its consequence the most then causes bearing to produce abnormal sound, heavy then cause bearing to lose greasy property, and hay mover can not work.
The reason being easily caused seal failure under above-mentioned bad working environments is:
(1) not having skeletal support at sealed end two, rigidity is poor, and under the operating mode of high speed, high temperature for a long time, sealed end two can deform and cause seal failure, and then causes water or silt to enter；
(2) secondary lip extends to the outer wall of inner ring, and seal groove two is not the most completely covered, and lubricating grease can leak to main lip, at main lip in the case of seal failure, will result in lubricating grease and reveals.
In view of above-mentioned severe working condition and the fault of construction of sealing ring, it is necessary to design the water-sealed bearing that a kind of sealing property is more preferable, service life is longer.
Summary of the invention
The technical problems to be solved in the utility model is to provide the water-sealed bearing that a kind of sealing property is more preferable, service life is longer.
In order to solve above-mentioned technical problem, the technical scheme that the utility model provides is as follows: a kind of bearing sealed ring, including ring-type sealed body, it is provided with skeleton in described sealed body, the outer ring of described sealed body is sealed end one, the inner ring of described sealed body is sealed end two, and described sealed end two includes main lip, secondary lip and dust excluder lips, and described skeleton is provided with the extension to sealed end 21 lateral buckling.
Further, it is provided with waist between described sealed body and sealed end two.
A kind of water-sealed bearing, including bearing inner race, bearing outer ring and above-mentioned bearing sealed ring, the seal groove one matched with described sealed end one it is provided with at the inside wall edge of described bearing outer ring, the seal groove two matched with described sealed end two it is provided with at the outer wall edge of described bearing inner race, described main lip and the bottom land interference fit of the madial wall interference fit of seal groove two, described dust excluder lips and described seal groove two.
Further, being provided with gap between described secondary lip and the outer wall of bearing inner race, described secondary lip is completely covered seal groove two in the radially projecting of bearing inner race.
Further, the bottom of described main lip is parallel with the bottom land of seal groove two.
Further, the axial magnitude of interference between described main lip and the madial wall of seal groove two is 0.1～0.15mm.
Further, the radial interference amount between described dust excluder lips and seal groove two bottom land is 0.05～0.1mm.
Bearing sealed ring of the present utility model and comprise the water-sealed bearing of this sealing ring, main lip and the axial interference fit of madial wall of seal groove two, dust excluder lips and the bottom land radial interference fit of seal groove two, can effectively prevent the water of outside, silt etc. from entering Bearing inner, it is also prevented from lubricating grease to reveal simultaneously, good seal performance, service life is long, it is possible to adapt to more severe working condition.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 2 show the partial structurtes schematic diagram of the present embodiment water-sealed bearing, and this water-sealed bearing includes bearing inner race 20, bearing outer ring 30 and bearing sealed ring.Wherein it is provided with seal groove 1 at the inside wall edge of bearing outer ring 30, at the outer wall edge of bearing inner race 20, is provided with the seal groove two 21 corresponding with seal groove 1.
As the improvement of the present embodiment, wherein bearing sealed ring includes ring-type sealed body 10, is provided with skeleton 40 in this sealed body 10.Wherein the outer ring of sealed body 10 is the sealed end 1 matched with seal groove 1, and the inner ring of sealed body 10 is the sealed end 2 12 matched with seal groove 2 21.
Further, the sealed end 2 12 of the present embodiment includes main lip 121, secondary lip 122 and dust excluder lips 123, and skeleton 40 is provided with the extension 41 to sealed end 2 12 1 lateral buckling.Under confined state, the most main lip 121 and the madial wall interference fit of seal groove 2 21, as preferably, the magnitude of interference along bearing axial direction is 0.1～0.15mm.It addition, the bottom of main lip is parallel with the bottom land of seal groove two, prevent from causing sealed end two bulk deformation because of the deformation of main lip.
The wherein bottom land interference fit of dust excluder lips 123 and seal groove 2 21, it is to avoid because of external action, makes main lip deform, and affects bearing seal performance.As preferably, the magnitude of interference along bearing radial direction is 0.05～0.1mm.Suitably the magnitude of interference, decides sealing property and the staring torque size of bearing.
In the present embodiment, secondary lip 122 self sealss main body 10 extends to the space between bearing inner race 20 and bearing outer ring 30, and it is provided with gap between secondary lip 122 and the outer wall of bearing inner race 20, prevents bearing inner race during bearing outer ring rotates, produce frictional resistance.Further, secondary lip 122 is completely covered seal groove 2 21 in the radially projecting of bearing inner race 20, the purpose of this structure is, in the case of High Rotation Speed, lubricating grease gets rid of the inwall to bearing outer ring 30 under the influence of centrifugal force, in lubricating grease reflux course, under the guiding function of secondary lip 122, grease flow is to the outer wall of bearing inner race, without entering in seal groove two, reduce the risk that lubricating grease is revealed, it is ensured that lubricating grease is in effective duty.
In the present embodiment, dust excluder lips 123 can be effectively prevented the materials such as the water of outside, silt and enter Bearing inner.Owing to the extension 41 of skeleton 40 produces certain pressure to sealed end two, effectively control the laminating degree between main lip and dust excluder lips and seal groove two, improve the sealing property of bearing.And can effectively control the staring torque of bearing by controlling the size of waist 13 between sealed body and sealed end two, improve the sealing property of bearing.
In a word, the foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
