Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a low-friction tapered roller bearing. Background Art

[0002] Bearings are a device used to reduce mechanical friction and are often used in mechanical equipment. They usually consist of an inner ring, an outer ring, rolling elements, and a retainer. The function of a bearing is to support and reduce the friction of rotation or movement, thereby improving the efficiency and life of mechanical equipment.

[0003] When existing bearings are in use, the outer ring is fixed and the inner ring rotates. When the inner ring rotates, it will produce friction with the seal at the end, so it is necessary to add lubricating oil to the bearing to reduce the friction inside the bearing. However, the lubricating oil is often not added to the bearing in time. At the same time, when the bearing rotates at high speed, the heat generated by friction will accumulate inside the bearing, so the temperature of the lubricating oil is too high, thereby reducing the viscosity of the lubricating oil and deteriorating the lubricating performance of the lubricating oil. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a low-friction tapered roller bearing, comprising a bearing assembly, an outer surface wall of the bearing assembly is provided with an oil storage assembly;

[0006] The bearing assembly includes an outer ring and an inner ring, the inner wall of the outer ring is provided with a first rolling groove, the outer wall of the inner ring is provided with a second rolling groove, the interior of the outer ring is provided with an oil filling circular groove, the inner wall of the first rolling groove is provided with a group of oil leakage holes, a group of the oil leakage holes are connected with the oil filling circular groove, a group of fan blades are fixedly installed at one end of the outer wall of the inner ring, and lubricating oil can be introduced into the interior of the oil filling circular groove through the oil storage assembly, and then the oil filling circular groove evenly adds the lubricating oil to the bearing assembly through the group of oil leakage holes, and the friction of the bearing assembly is reduced by the lubricating effect of the lubricating oil, and the inner ring will drive the fan blades to rotate during the rotation process, thereby cooling the bearing assembly.

[0007] Preferably, a retaining frame is arranged between the outer ring and the inner ring, and a group of rollers are rotatably mounted on the retaining frame. The group of rollers are rollingly arranged on the inner walls of the first rolling groove and the second rolling groove, and the outer ring and the inner ring can rotate relative to each other through the group of rollers.

[0008] Preferably, a first circular placement groove is symmetrically opened on both sides of the outer wall of the outer ring, and a second circular placement groove is symmetrically opened on both sides of the outer wall of the inner ring. Filter mesh covers are arranged at both ends of the outer wall of the outer ring, and the end faces of the filter mesh covers are matched with the first circular placement groove and the second circular placement groove respectively. The filter mesh covers can prevent external dust and impurities from entering the interior of the bearing assembly.

[0009] Preferably, the oil storage assembly comprises an oil storage box, an oil filling cap is arranged at the top end of the oil storage box, a threaded sleeve is fixedly installed at the top end of the oil storage box, and lubricating oil can be added into the oil storage box through the oil filling cap.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when the bearing assembly is in use, lubricating oil can be introduced into the oil filling groove through the oil storage assembly, and then the oil filling groove adds the lubricating oil to the bearing assembly evenly through a group of oil leakage holes. The lubricating effect of the lubricating oil reduces the friction of the bearing assembly. When the bearing assembly rotates for a long time, the heat generated by the friction will accumulate inside the bearing, causing the temperature of the lubricating oil in the bearing to be too high. In order to prevent the temperature of the lubricating oil from being too high, thereby reducing the viscosity of the lubricating oil and deteriorating the lubricating performance of the lubricating oil, a group of fan blades are arranged on the inner ring. The inner ring will drive the fan blades to rotate during the rotation process. When the fan blades rotate, the air flow speed is increased. When the flowing air passes through the inside of the bearing assembly, it will take away the heat in the bearing assembly, thereby reducing the temperature of the lubricating oil and preventing the lubricating oil temperature from being too high and affecting the lubrication effect.

Lubricating oil can be introduced into the inside of the oil filling groove 110 through the oil storage assembly 2, and then the oil filling groove 110 evenly adds the lubricating oil to the bearing assembly 1 through the group of oil leakage holes 111. The lubricating effect of the lubricating oil reduces the friction of the bearing assembly 1. The inner ring 106 will drive the fan blades 109 to rotate during the rotation, thereby cooling the bearing assembly 1.

[0027] like Figure 1-Figure 7 As shown, a retaining frame 104 is arranged between the outer ring 101 and the inner ring 106 , and a group of rollers 105 are rotatably mounted on the retaining frame 104 .

[0028] like Figure 1-Figure 7 As shown, first circular grooves 102 are symmetrically provided on both sides of the outer wall of the outer ring 101, and second circular grooves 108 are symmetrically provided on both sides of the outer wall of the inner ring 106. Filter screen covers 3 are arranged at both ends of the outer wall of the outer ring 101, and the end faces of the filter screen covers 3 are matched with the first circular groove 102 and the second circular groove 108 respectively. The filter screen cover 3 can prevent external dust and impurities from entering the interior of the bearing assembly 2.

[0030] like Figure 1-Figure 7 As shown, the inner wall of the threaded sleeve 203 is threadedly connected to the threaded rod 202, the output shaft of the threaded rod 202 passes through the top of the oil storage box 201, and a plug 206 is fixedly installed. A rotating plate 204 is fixedly installed on the top of the threaded rod 202, and the rotating plate 204 drives the threaded rod 202 to rotate in the threaded sleeve 203.

The lubricating effect of the lubricating oil reduces the friction of the bearing assembly 1. When the bearing assembly 1 rotates for a long time, the heat generated by the friction will accumulate inside the bearing, causing the lubricating oil temperature in the bearing to be too high. In order to prevent the lubricating oil temperature from being too high, Thereby, the viscosity of the lubricating oil is reduced and the lubricating performance of the lubricating oil is deteriorated.
