Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bearings, specifically a novel heavy-duty cylindrical roller bearing. Background Technology
[0002] Cylindrical roller bearings generally consist of an inner ring, an outer ring, and rolling elements. These bearings are mainly used as support bearings in logistics and warehousing machinery and various track-based translation devices. During use, the speed of the outer ring and rolling elements is generally not high, but the bearing must withstand radial loads of several tons or even tens of tons and perform continuous reciprocating motion. Moreover, the bearing is often exposed to harsh natural environments. Therefore, long-term use can easily cause corrosion of the rolling elements between the inner and outer rings by external contaminants, affecting the service life. At the same time, they do not have the function of limiting the movement of the inner ring. During use, the inner ring is prone to axial movement, affecting the stability of use. Utility Model Content
[0003] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a novel heavy-duty cylindrical roller bearing, including an outer bearing ring, an inner bearing ring inside the outer bearing ring, a pair of annular grooves formed on the inner wall surface of the outer bearing ring, and a first ball in the annular grooves that contacts the outer surface of the inner bearing ring.
[0004] A limiting ring is fixedly installed on the outer surface of one end of the inner ring of the bearing, and one end face of the limiting ring is in contact with one end face of the outer ring of the bearing.
[0005] An annular limiting groove is formed on the outer surface of the inner ring of the bearing, and a pair of arc-shaped blocks are provided on one end face of the outer ring of the bearing. An arc-shaped limiting block that is slidably connected to the annular limiting groove is fixedly installed on the inner surface of the arc-shaped blocks.
[0006] Preferably, an annular groove is formed on one end face of the outer ring of the bearing;
[0007] A limiting slider that is slidably connected to the annular groove is fixedly installed on one end face of the limiting ring.
[0008] Preferably, a groove is formed on the inner surface of the arc-shaped limiting block, and a second ball bearing is provided in the groove that contacts the inner wall of the annular limiting groove.
[0009] Preferably, a threaded groove is formed in one end face of the outer ring of the bearing, and a bolt that is threadedly connected to the threaded groove is provided on the arc-shaped block.
[0010] The beneficial technical effects of this utility model are as follows: under the action of the limiting ring, a pair of arc-shaped blocks, a pair of arc-shaped limiting blocks and an annular limiting groove, not only can the position of the bearing inner ring within the bearing outer ring be limited to prevent axial movement during use and affecting its use, but it can also seal the gap between the bearing outer ring and the bearing inner ring to prevent external contaminants from corroding the first ball and affecting its service life, thus bringing convenience to people.

Detailed Implementation
[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0017] This utility model proposes a novel heavy-duty cylindrical roller bearing, including an outer bearing ring 1, an inner bearing ring 2 inside the outer bearing ring 1, a pair of annular grooves 3 formed on the inner wall surface of the outer bearing ring 1, and a first ball 4 in contact with the outer surface of the inner bearing ring 2 inside the annular grooves 3.
[0018] The inner ring 2 of the bearing is rotatably disposed within the outer ring 1 of the bearing. A plurality of first balls 4 are disposed in the annular groove 3. The outer surfaces of the first balls 4 are in contact with the outer surface of the inner ring 2 of the bearing, which can make the inner ring 2 rotate more smoothly. At the same time, a pair of first balls 4 in the annular groove 3 can simultaneously bear the load of the inner ring 2 of the bearing, which can improve the load-bearing capacity of the inner ring 2 of the bearing.
[0019] A limiting ring 5 is fixedly installed on the outer surface of one end of the inner ring 2 of the bearing, and one end face of the limiting ring 5 is in contact with one end face of the outer ring 1 of the bearing.
[0020] One end face of the limiting ring 5 slides in contact with one end face of the outer ring 1 of the bearing, which can limit the inner ring 2 of the bearing and prevent it from moving out of the outer ring 1 of the bearing.
[0021] An annular limiting groove 6 is formed on the outer surface of the inner ring 2 of the bearing, and a pair of arc-shaped blocks 7 are provided on one end face of the outer ring 1 of the bearing. An arc-shaped limiting block 8 that is slidably connected to the annular limiting groove 6 is fixedly installed on the inner surface of the arc-shaped block 7.
[0022] A pair of arc-shaped blocks 7 are fixedly installed on one end face of the outer ring 1 of the bearing, and can be relatively fixed. At the same time, when the inner ring 2 of the bearing rotates, the arc-shaped limiting block 8 slides in the annular limiting groove 6. At this time, with the cooperation of the pair of arc-shaped limiting blocks 8 and the limiting ring 5, the inner ring 2 of the bearing can rotate stably in the outer ring 1 of the bearing, preventing it from moving axially and affecting the stability of use.
[0023] Specifically, an annular groove 9 is formed on one end face of the outer ring 1 of the bearing;
[0024] A limiting slider 10, which is slidably connected to the annular groove 9, is fixedly installed on one end face of the limiting ring 5;
[0025] When the inner ring 2 of the bearing rotates, it can drive the limiting ring 5 and the limiting slider 10 to rotate, so that the limiting slider 10 slides in the annular groove 9. Under the action of the annular groove 9 and the limiting slider 10, the inner ring 2 of the bearing can remain stable when it rotates.
[0026] Specifically, a groove 11 is formed on the inner surface of the arc-shaped limiting block 8, and a second ball 12 that contacts the inner wall of the annular limiting groove 6 is provided in the groove 11.
[0027] The number of second balls 12 is several, and they are respectively set in a pair of grooves 11. At the same time, when the inner ring 2 of the bearing rotates, the inner wall surface of the annular limiting groove 6 contacts the outer surface of the second balls 12, which can make the rotation of the inner ring 2 of the bearing smoother.
[0028] Specifically, a threaded groove 13 is formed in one end face of the outer ring 1 of the bearing, and a bolt 14 is provided on the arc-shaped block 7 that is threadedly connected to the threaded groove 13.
[0029] One end of the bolt 14 is threaded into the threaded groove 13, which can fix the arc-shaped block 7 to one end face of the outer ring 1 of the bearing, and at the same time, it can facilitate the disassembly of the arc-shaped block 7 for easy maintenance.
[0030] Working principle: In actual use, firstly, several first balls 4 are placed into a pair of annular grooves 3, and the inner ring 2 of the bearing is inserted into the outer ring 1 of the bearing. At the same time, the annular slider 10 is inserted into the annular groove 9, so that the outer surface of the first balls 4 contacts the outer surface of the inner ring 2 of the bearing. At this time, a pair of arc-shaped limiting blocks 8 are inserted into the annular limiting grooves 6. At the same time, the bolt 14 is rotated so that one end is threaded into the threaded groove 13, and the arc-shaped block 7 is fixed relative to the outer ring 1 of the bearing. At this time, under the action of the pair of arc-shaped limiting blocks 8 and the limiting ring 5, the inner ring 2 of the bearing can be limited to prevent its axial movement and keep it stable when rotating. At the same time, when the inner ring 2 of the bearing rotates, the outer surface of the second ball 12 contacts the inner wall of the annular limiting groove 6, which can improve the stability of the rotation of the inner ring 2 of the bearing and reduce friction, bringing convenience to people.
