Description

Technical Field

[0001] The utility model relates to the technical field of deep groove ball bearings, in particular to a wear-resistant deep groove ball bearing. Background Art

[0002] Deep groove ball bearings are the most widely used rolling bearings. Their main features are low friction resistance and high speed. They can be used on parts that bear radial loads or combined loads of radial and axial forces, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, etc.

[0003] A Chinese patent discloses a wear-resistant deep groove ball bearing structure with high heat dissipation (authorization announcement number CN210509952U). This patented technology dissipates heat and cools the bearing by providing heat dissipation holes and heat sinks, thereby reducing the damage rate of the bearing, improving the operating efficiency of the bearing, and extending the service life of the bearing.

[0004] However, there are still some shortcomings in this patent. Although this patent can achieve the purpose of heat dissipation, it can be seen from the drawings of this patent that this patent does not have air filtration when dissipating heat, which causes dust to enter and affect the use of the bearing. At the same time, the bearing will wear out without lubrication when used for a long time, resulting in a reduction in its service life. Therefore, those skilled in the art provide a wear-resistant deep groove ball bearing to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to provide a wear-resistant deep groove ball bearing to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wear-resistant deep groove ball bearing comprises a bearing body, wherein the bearing body is composed of a bearing outer ring, a bearing inner ring arranged on the inner side of the bearing outer ring, and a ball arranged between the bearing inner ring and the bearing outer ring; a protective mechanism is inserted into the gap between the front surface and the rear surface of the bearing outer ring and the bearing inner ring; the protective mechanism comprises a second protective plate and a first protective plate arranged from left to right in the gap between the front surface and the rear surface of the bearing outer ring and the bearing inner ring; a groove is provided on the front surface of the first protective plate and the second protective plate; a filtering mechanism is symmetrically provided on the outside of the bearing outer ring; the filtering mechanism comprises a second fixed groove provided on the outside of the bearing outer ring, and a filter screen is embedded and installed inside the second fixed groove.

[0008] As a further solution of the present invention: the first protective plate and the second protective plate are both semicircular in shape, and the groove is opened in a "U" shape on the front surfaces of the first protective plate and the second protective plate.

[0009] As a further solution of the utility model: a positioning plate is symmetrically arranged on one side of the second protective plate, and a positioning groove which engages with the positioning plate is opened on one side of the first protective plate.

[0010] As a further solution of the utility model: a first fixing groove which is interpenetrating with the second fixing groove is further provided inside the outer ring of the bearing, and the radius of the first fixing groove is smaller than that of the second fixing groove.

[0011] As a further solution of the utility model: locking bolts are symmetrically arranged on the upper surface of the filter screen, a mounting hole is opened inside the outer ring of the bearing, and the end of the locking bolt is embedded in the mounting hole and threadedly connected to the mounting hole.

[0012] As a further solution of the utility model: the upper surface of the filter is flush with the upper surface of the bearing outer ring, and four second fixing grooves are symmetrically opened on the outside of the bearing outer ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model provides a first fixing groove and a second fixing groove inside the outer ring of the bearing, and the inside of the second fixing groove is installed on the filter screen through a locking bolt, so that the incoming lubricating oil can be filtered through the filter screen, and dust can also be prevented. By adding lubricating oil, the deep groove ball bearing can have good wear resistance, thereby increasing the service life of the bearing body.

[0015] 2. The utility model can achieve the purpose of dust prevention through the protective mechanism, avoiding the entry of dust and affecting the normal use of the bearing body. At the same time, the first protective plate and the second protective plate in the protective mechanism are installed and disassembled by embedding the positioning plate in the positioning groove, which makes it easy to replace the first protective plate and the second protective plate.
