Description

Technical Field

[0001] The utility model relates to the technical field of spherical roller bearings, in particular to a spherical roller bearing with a protective structure. Background Art

[0002] The spherical roller bearing has double-row rollers, a common spherical raceway on the outer ring, and two raceways on the inner ring that are tilted at an angle relative to the bearing axis. This ingenious structure enables it to have self-aligning performance, so it is not easily affected by the angle error between the shaft and the bearing box seat or the shaft bending, and is suitable for occasions where the angle error is caused by installation error or shaft deflection. In addition to being able to withstand radial loads, the bearing can also withstand bidirectional axial loads.

[0003] After being used for a period of time, the lubricating oil inside the existing spherical roller bearing is easily consumed, which increases the friction between the roller and the inner wall of the bearing and between the inside of the bearing, causing wear on the inside of the bearing and shortening its service life.

[0025] Embodiment 2:

[0026] like Figure 2-3As shown, the structure of the spherical roller bearing disclosed in the second embodiment of the utility model is basically the same as that in the first embodiment, except that a plurality of pockets are provided on both sides of the bearing retainer 3, and rollers 5 are placed in the pockets, the inner side of the rollers 5 abuts against the inner wall of the pockets, and the outer side of the rollers 5 abuts against the baffle 21 on the outer side of the bearing inner ring 2.

The rollers 5 are rotatably connected to the bracket 6, and the upper part of the rollers 5 movably abuts against the inner wall of the bearing outer ring 1.

[0027] Embodiment three:

[0028] like Figure 4 As shown, the structure of the spherical roller bearing disclosed in the third embodiment of the utility model is basically the same as that in the second embodiment, except that the oil outlet mechanism includes an oil box 4 and a bracket 6, the bottom of the pocket of the bearing retainer 3 is installed with an oil box 4, the upper middle part of the oil box 4 is provided with an opening, and a spring 41 is provided at the opening of the oil box 4, and the upper four corners of the spring 41 are fixedly connected to the upper inner wall of the oil box 4. The upper part of the oil box 4 is vertically slidably connected with the bracket 6, and the lower middle part of the bracket 6 is fixedly connected with a conduit 62, and the guide groove in the middle of the conduit 62 passes through the upper middle part of the bracket 6 and is connected with the oil groove 61 in the upper middle part of the bracket 6. The outer side of the conduit 62 is provided with a spring 63, the upper end of the spring 63 is fixedly connected to the lower middle part of the bracket 6, and the lower end of the spring 63 is fixedly connected to the upper part of the oil box 4.

[0029] The specific solution of this invention is as follows: when the bearing is used for a long time, the lubricating oil on its surface becomes dry and solidified, so that the roller 5 generates a large friction with the inner wall of the bearing during the rotation process, so that the roller 5 cannot rotate, thereby causing the outer ring 1 of the bearing and the inner ring 2 of the bearing to be squeezed, that is, the roller 5 squeezes the bracket 6 inward, pushing the bracket 6 inward, so that the guide tube 62 moves vertically downward and abuts against the spring sheet 41, and the spring sheet 41 is squeezed downward, so that the opening above the oil box 4 is opened, and the lubricating oil in the oil box 4 rises to the upper side through the guide tube 62. In the oil groove 61, when the roller 5 rotates, the lubricating oil is brought out by the rotation of the roller 5, so that the lubricating oil adheres to the outer wall of the roller 5 and the inner wall of the bearing during the use of the bearing to lubricate them, facilitate the rotation of the roller 5 and the relative rotation between the outer ring 1 of the bearing and the inner ring 2 of the bearing, and when the roller 5 can fully rotate, the outer ring 1 of the bearing will not be relatively squeezed with the inner ring 2 of the bearing. Under the elastic force of the spring 63, the bracket 6 pushes the roller 5 to move outward, so that the roller 5 presses against the inner wall of the outer ring 1 of the bearing, so that the bearing can be used normally.
