Description

Technical Field

[0001] This utility model belongs to the technical field of cylindrical roller bearings, specifically a wear-resistant cylindrical roller bearing. Background Technology

[0002] Cylindrical roller bearings are radial rolling bearings in which the rolling elements are cylindrical rollers. The internal structure of cylindrical roller bearings uses rollers arranged in parallel, with spacers or spacers between the rollers to prevent the rollers from tilting or rubbing against each other, effectively preventing an increase in rotational torque.

[0003] Existing cylindrical roller bearings have relatively complete structure and function, and can meet basic usage requirements, but the following problems still exist:

[0004] In actual use, when the cylindrical rollers rotate relative to the outer and inner rings of the bearing, the friction between them will cause increased wear, which will affect the actual service life of the cylindrical rollers and the outer and inner rings of the bearing, which is very inconvenient. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a wear-resistant cylindrical roller bearing, which solves the problem that when the cylindrical rollers rotate with the bearing outer ring and the bearing inner ring in actual use, the wear will be aggravated due to mutual friction, which will affect the actual service life of the circumferential rollers and the bearing outer ring and the bearing inner ring, which is very inconvenient.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant cylindrical roller bearing, comprising an outer bearing ring and an inner bearing ring, a cage installed between the outer and inner bearing rings, cylindrical rollers disposed inside the cage, a lubrication dripping structure disposed inside the inner bearing ring, and disassembly and assembly protection structures disposed on both sides of the inner bearing ring, the lubrication dripping structure comprising an oil reservoir formed on the inner wall of the inner bearing ring, an oil injection hole formed on one side of the inner bearing ring, and the disassembly and assembly protection structure comprising an annular groove formed on one side of the inner bearing ring.

[0009] As a further embodiment of this utility model: a piston block is engaged with the inner wall of the oil injection hole, and an operating block is fixedly connected to one side of the piston block.

[0010] As a further embodiment of this utility model: a storage groove is provided on one side of the inner ring of the bearing, and the operating block on one side of the piston block is engaged with the storage groove.

[0011] As a further embodiment of this utility model: a circular groove is provided at the top of the inner ring of the bearing, an oil outlet groove is provided at the bottom of the circular groove, a sliding rod is inserted into the inner wall of the oil outlet groove, and a circular plug is fixedly connected to the bottom end of the sliding rod.

The two ends of the return spring are fixedly connected to the circular groove and the pressing block, respectively.

[0013] As a further embodiment of this utility model: an annular card block is engaged with the inner wall of the annular card slot, and a rubber ring plate is fixedly connected to the outer surface of the annular card block.

[0014] As a further embodiment of this utility model: the inner wall of the annular card block is provided with a second screw hole, the inner wall of the annular card groove is provided with a first screw hole, and the inner walls of the first screw hole and the second screw hole are threadedly connected with a threaded card rod.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This wear-resistant cylindrical roller bearing, through the setting of a lubrication drip structure, allows the cylindrical rollers to squeeze the pressing block under the action of the sliding rod. The pressing block drives the sliding rod to move up and down, which in turn drives the circular plug to move up and down, thereby sealing and unsealing the oil outlet hole. Oil can be discharged after one press, and the pressing block can be reset under the action of the return spring. In this way, oil lubrication can be repeatedly performed.

[0018] 2. This wear-resistant cylindrical roller bearing, by setting an oil injection hole, allows oil to be injected into the oil reservoir. At the same time, the oil injection hole can be auxiliaryly sealed by the action of the piston block. Meanwhile, the storage groove can store the operating block on the piston block.

[0019] 3. This wear-resistant cylindrical roller bearing, through the setting of a disassembly and assembly protection structure, can assist in the disassembly and assembly of the rubber ring plate under the action of the annular retaining block and the annular retaining groove, thereby protecting the middle area of ​​the bearing outer ring and the bearing inner ring.
