Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a dustproof bearing with a baffle structure. Background Art

[0002] Bearings are a widely used mechanical component. Whether it is airplanes, automobiles, ships, machine tools, motors, or household appliances, bearings are indispensable wherever there is a rotating support. Bearings mainly include an inner ring, an outer ring and the rollers between the two. Currently, the use of bearings is very wide, so they often encounter harsh environments. Dust will enter the bearings and adhere to the rollers, causing the friction coefficient of the bearings themselves to increase, seriously leading to bearing failure.

[0003] After searching, the utility model patent with patent announcement number CN214661552U discloses a dustproof bearing, including a bearing outer ring, a bearing inner ring, a rotating body arranged between the bearing outer ring and the bearing inner ring, and a dust cover arranged between the bearing outer ring and the bearing inner ring; the dust cover is annular, and there are two dust covers, which are arranged at both ends of the bearing outer ring and the bearing inner ring, respectively, and the outer ring of the dust cover is detachably connected to the end face of the bearing outer ring, and the inner ring of the dust cover is slidably connected to the end face of the bearing inner ring. After the bearing has been working for a period of time, the staff can take out the bearing, remove the sealing cover, and replace the deteriorated grease inside the bearing to reduce the impact of the deteriorated grease on the bearing, thereby extending the service life of the bearing.

[0004] However, the above design still has some shortcomings. Since it is fixed by a large number of bolts during installation, it is difficult to disassemble during maintenance. In particular, the fixing bolts are prone to rust, which makes the disassembly process cumbersome. Therefore, we propose a dust-proof bearing with a baffle structure to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a dustproof bearing with a baffle structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dustproof bearing with a baffle structure, comprising an inner ring, an outer ring is arranged outside the inner ring, a plurality of balls are arranged between the outer ring and the inner ring, two baffle bodies are arranged above the inner ring, an outer surface of each baffle body is provided with a mounting assembly for mounting the baffle body, a plurality of fixing assemblies for fixing the baffle body are arranged inside the outer ring, the mounting assembly comprises a connecting plate fixed on the outer surface of the baffle body, an extrusion spring is fixed to the bottom surface of the connecting plate, and a movable plate is fixed to the bottom end of each extrusion spring.

[0007] Wherein, the fixing component comprises a notch opened on the outer surface of the outer ring, the inner wall of the notch is provided with a slide groove, and the inner top wall of the slide groove is provided with a fixing groove.

[0008] The outer surface of the baffle body is provided with four sliding grooves, the interior of each sliding groove is slidably connected with a sliding block, and the outer surface of each sliding block is connected to the outer surface of the moving plate.

[0009] Wherein, two hand-held blocks are fixed on the outer surface of each baffle body.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model can effectively prevent dust and other particles from entering the interior of the bearing through the design of the baffle body, thereby improving the working performance and life of the bearing in harsh environments. Through the cooperation of the connecting plate, the extrusion spring and the moving plate, the baffle body can slide back and forth in the slide groove until the connecting plate is inserted into the fixing groove to fix the baffle body. This design simplifies the installation process, eliminates the need for complicated alignment and adjustment, improves the installation efficiency, and makes the maintenance of the bearing easier. The maintenance personnel can quickly disassemble the baffle body for cleaning and lubrication without the need for additional tools or complicated steps. BRIEF DESCRIPTION OF THE DRAWINGS
