Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1, 2, 3 and 4, a bearing structure capable of fully filling a cylindrical roller 10 comprises an inner ring 8 and an outer ring 6, wherein a plurality of rollers 10 are installed between the inner ring 8 and the outer ring 6, and is characterized by further comprising a first sealing ring 1, the first sealing ring 1 is circular, the outer diameter of the first sealing ring 1 is in contact with the inner diameter of the outer ring 6, the second sealing ring 3 is circular, the inner diameter of the second sealing ring is in contact with the outer diameter of the inner ring 8, a circular sliding rail is arranged on the first sealing ring 1, the second sealing ring 3 is in sliding fit with the sliding rail, and by arranging the first sealing ring 1 and the second sealing ring 3, the friction caused by the rotation of the outer ring 6 and the inner ring 8 can be reduced, so that the damage caused by the abrasion between the sealing ring and a bearing main body is reduced, and the service life of the sealing ring is prolonged, all be equipped with spacing groove 9 on outer lane 6 and the inner circle 8, all be equipped with on first sealing washer 1 and the second sealing washer 3 with spacing groove 9 complex spacing subassembly, through the cooperation that sets up spacing groove 9 and spacing subassembly, can realize the fixed of first sealing washer 1 and second sealing washer 3 position during the use, realize that the sealing washer can realize the life to the sealing of bearing. In actual production, the existing structure, the full-complement roller bearing, is inaccurate in practice, namely the number of rollers of the bearing designed by the prior structure is possibly not an integer, so that the gap between the rollers is too large, impact sound is generated in the middle of the bearing operation process, and the noise is high.

During specific implementation, be equipped with recess 7 on the outer face of cylinder of outer lane 6, recess 7 is inside to be equipped with the oil pipe 5 that adds with

outer lane

6 and 8 clearance intercommunications of inner circle, for the convenience of carrying out the interpolation of lubricating oil to roller 10 in the middle of inner circle 8 and the outer lane 6, can convenient to use person carry out the interpolation of lubricating oil through the oil pipe 5 that adds that sets up, adopts recess 7 setting to protect oil pipe 5 simultaneously.

During concrete implementation, the threaded fit has sealed lid 4 on filling oil pipe 5, can protect filling oil pipe 5 through setting up sealed lid 4, reduces the entering of dust simultaneously, the further life who improves the bearing.

During concrete implementation, spacing subassembly is including rotating bull stick 12 of installing on first sealing washer 1 and second sealing washer 3, bull stick 12 is served towards the rotor and all installs limiting plate 2, and limiting plate 2's turned angle is 100 degrees, through rotating bull stick 12 during the use, realizes two limiting plate 2's rotation to realize limiting plate 2 and spacing groove 9's cooperation and separation, and then realize the quick assembly disassembly of sealing washer, further improve the result of use of device.

During specific implementation, the cover has the torsional spring that the drive bull stick 12 resets on the bull stick 12, and through setting up the torsional spring, the 2 initial positions of limiting plate are the position with spacing groove 9 matched with, and then can realize the reduction of limiting plate 2 under the drive of torsional spring, and then ensure the normal use of sealing washer.

During specific implementation, be equipped with the oil-out on first sealing washer 1, rotate on the oil-out and install and go out oil plate 11 with oil-out complex, in order to avoid discharging the old oil of remaining lubricating oil of inside, through setting up out oil plate 11, will go out oil plate 11 and rotate to the clearance between inner circle 8 and the outer lane 6 during the use to make the bearing and go out oil plate 11 and produce relative rotation, and then realize striking off the old oil of inside, improve the discharge rate of old oil.
