Description

Technical Field

[0001] The utility model relates to the technical field of spherical roller bearings, in particular to a high-load-bearing spherical roller bearing. Background Art

[0002] Spherical roller bearings are bearings with drum-shaped rollers assembled between an inner ring with two raceways and an outer ring with a spherical raceway. Spherical roller bearings have two rows of rollers and mainly bear radial loads, but can also bear axial loads in any direction. They have high radial load capacity and are particularly suitable for working under heavy loads or vibration loads.

[0003] The inner ring of the existing spherical roller bearing is mainly subjected to load impact, and the impact force is radially transmitted from the center to the outer retaining frame. Since the retaining frame is provided with grooves for mounting rollers, the internal retaining frame of the spherical roller bearing is easily deformed under the action of radial impact force after long-term use, thereby affecting the rotation of the roller and thus affecting its service life. Therefore, there is room for improvement. Utility Model Content

[0008] Preferably, an anti-skid pad is provided on the inner side of the connecting ring, and the anti-skid pad is in close contact with the outer wall of the outer fixing column and the inner fixing column.

[0014] (2) The annular oil guide groove and the guide channel can be used to evenly guide the lubricating oil into the slot, thereby improving the lubrication effect on the surface of the roller body, reducing the rotational friction of the roller body, and increasing the service life of the spherical roller bearing.

[0024] The top ends of the external fixing column 301 and the internal fixing column 302 are both sleeved with a locking cap 10, and the interior of the locking cap 10 is connected to the external fixing column 301 and the internal fixing column 302 through threads;

[0025] The inner side of the connecting ring 303 is provided with an anti-skid pad, and the anti-skid pad is in close contact with the outer wall of the outer fixing column 301 and the inner fixing column 302;

[0026] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, when in use, the left and right sides of the anti-slip pad are used to improve the contact tightness between the connecting ring 303 and the outer fixing column 301 and the inner fixing column 302, so as to prevent the upper and lower misalignment of the inner and outer apex positions of the connecting rod 304, so as to ensure the uniform transmission of the radial impact force by the connecting rod 304, and the locking cap 10 is used to realize the detachability of the connecting rod 304, so as to facilitate its replacement;

[0027] An oil guide mechanism 9 is provided between the bearing outer ring 1 and the retaining frame 2;

[0028] The oil guide mechanism 9 includes an annular oil guide groove 901 formed on the outer side of the retainer 2, and guide channels 902 are evenly formed at both ends of the annular oil guide groove 901, one end of the guide channel 902 is connected to the clamping groove 5, and oil inlet holes 903 are formed on both sides of the bearing outer ring 1;

[0029] The position of the oil inlet hole 903 corresponds to the position of the annular oil guide groove 901 inside and outside, and the diameter of the oil inlet hole 903 matches the width of the annular oil guide groove 901;

[0030] The inner diameter of the flow guiding channel 902 gradually decreases from the inside to the outside, that is, the inner diameter of one end of the flow guiding channel 902 close to the annular oil guiding groove 901 is larger than the inner diameter of the other end;

[0031] Specifically, Figure 1 , Figure 2 As shown, when in use, the annular oil guide groove 901 and the guide channel 902 are used to guide the lubricating oil, so that the lubricating oil can flow to the roller body 6 more specifically, thereby improving the rotation smoothness of the roller body 6;

During the use of the spherical roller bearing, the function of the connecting rod 304 is utilized to facilitate the uniform and dispersed transmission of the radial impact received by the inner side of the bearing inner ring 4 to the retaining frame 2, and because the positions of the outer fixing column 301 and the slot 5 are staggered, the radial impact force can be uniformly dispersed on the slot 5, avoiding the single force on the side of the slot 5 close to the axis, thereby reducing the deformation of the slot 5, so as to further ensure the rotation stability of the roller body 6, thereby improving the radial load-bearing impact force of the spherical roller bearing;

[0034] Secondly, lubricating oil is injected into the spherical roller bearing through the oil inlet hole 903, so that the lubricating oil flows to the annular oil guide groove 901, and then is transmitted to the inside of the slot 5 through the guide channel 902, so as to lubricate the surface of the roller body 6 in the slot 5, so as to further improve the smoothness of the rotation of the roller body 6;

[0035] Finally, the oil-absorbing cotton 8 on the end surface is used to absorb the excess lubricating oil flowing outward along the card slot 5, and the porous structure of the sponge ring 7 is used to temporarily store the excess lubricating oil to prevent the lubricating oil from flowing around.
