Abstract
Description
Technical Field
[0001] The present invention relates to a roller bearing, in particular to an elastic bearing. Background Art
[0002] Bearings are a crucial component in modern mechanical equipment. Their primary function is to support rotating mechanical parts, reduce friction during movement, and ensure rotational accuracy. Roller bearings can be categorized as cylindrical roller bearings, tapered roller bearings, spherical roller bearings, and needle roller bearings. Existing bearings are all rigid, with the exception of spiral roller bearings, which are elastic. Bearings operating in harsh, high-temperature environments often face high temperatures and radial and axial forces. Spiral roller bearings are impact-resistant and heat-resistant, but under harsh operating conditions of heavy loads and shock loads, they can only accommodate radial expansion and contraction caused by radial forces, lacking axial expansion and contraction. This can easily cause clearance changes, leading to bearing seizure and shortened bearing life. Summary of the Invention

By staggeredly providing bevel grooves at both ends of the outer ring and the inner ring, the outer ring and the inner ring respectively form a wavy ring structure, and staggeredly providing through grooves at both ends of the cylindrical roller, the cylindrical roller forms a wavy ring structure. Since the outer ring, the inner ring and the cylindrical roller are respectively made of elastic metal, the outer ring, the inner ring and the cylindrical roller can be elastic in both the axial and radial directions, thereby achieving the purpose of effectively compensating for bearing wear.
[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:
[0005] An elastic bearing comprises an outer ring, a cylindrical roller and an inner ring, wherein a raised ring A is provided at one end of the inner wall of the outer ring, a plurality of outer ring bevel grooves A are provided at equal intervals at one end of the outer ring located at the raised ring A, a plurality of outer ring bevel grooves B are provided at equal intervals staggered and parallel to the outer ring bevel grooves A at the other end of the outer ring, so that the outer ring forms a wave-shaped ring structure A, a raised ring B is provided at one end of the inner ring outer wall of the inner ring, a plurality of inner ring bevel grooves A are provided at equal intervals at one end of the inner ring located at the raised ring B, a plurality of inner ring bevel grooves B are provided at equal intervals staggered and parallel to the inner ring bevel grooves A at the other end of the inner ring, so that the inner ring forms a wave-shaped ring structure B, a through hole concentric with the cylindrical roller is provided between the two bottom surfaces of the cylindrical roller, and a through hole concentric with the cylindrical roller is provided at equal intervals at one end of the cylindrical roller. A plurality of through grooves A are provided at intervals, and a plurality of through grooves B are provided at equal intervals on the other end of the cylindrical roller, staggered with the through grooves A, so that the cylindrical roller forms a wave ring structure, and a plurality of plug posts are provided at intervals on a bottom surface of the annular plate A, and a plurality of cylindrical rollers are respectively sleeved on the plurality of plug posts by means of perforations, and the ends of the plurality of plug posts are respectively fixed to a bottom surface of the annular plate B, and the other end of the inner ring passes through the holes respectively provided on the annular plate B and the annular plate A in sequence, and the plurality of cylindrical rollers are respectively in contact with the outer wall of the inner ring, and one end of the plurality of cylindrical rollers are respectively in contact with the raised ring B, and the other end of the outer ring is sleeved on the outside of the annular plate B and the annular plate A, and the plurality of cylindrical rollers are respectively in contact with the inner wall of the outer ring, and the other ends of the plurality of cylindrical rollers are respectively in contact with the raised ring A.
[0006] The elastic bearing has screw holes at the ends of the multiple pins, and through holes are provided on the annular plate B corresponding to the multiple pins. Multiple pins pass through the multiple through holes and are fixed to the multiple screw holes.
[0007] The elastic bearing is provided with expanded necks at one end of each of the plurality of through holes, and the nail caps provided on each of the plurality of pins are located in the plurality of expanded necks.
[0008] In the elastic bearing, the outer ring bevel groove A and the outer ring bevel groove B are inclined at an angle of 45 degrees relative to the axis of the outer ring.
[0009] In the elastic bearing, the inner ring bevel groove A and the inner ring bevel groove B are inclined at an angle of 45 degrees relative to the axis of the inner ring.
[0010] The outer ring, cylindrical roller and inner ring of the elastic bearing are made of elastic metal respectively.
[0011] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

Since the outer ring, inner ring and cylindrical roller are respectively made of elastic metal, the outer ring, inner ring and cylindrical roller can be elastic in both axial and radial directions, achieving the purpose of effectively compensating for bearing wear. The staggered bevel grooves at both ends of the outer ring and inner ring prevent the cylindrical roller from getting stuck in the bevel groove when rolling over it. The present invention has a novel and unique design, strong axial and radial compensation forces, stable operation, and great market promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
