Description

Technical Field

[0001] The utility model relates to the technical field of bearing grease injection devices, in particular to a bearing grease injection device used for deep groove ball bearings. Background Art

[0002] Deep groove ball bearings are suitable for high and even extremely high speed operation, are extremely durable, and require little maintenance. These bearings offer a low coefficient of friction, a high maximum speed, and come in a wide variety of sizes and styles. They are used in precision instruments, low-noise motors, automobiles, motorcycles, and general machinery, making them the most widely used type of bearing in the machinery industry.

[0003] After searching, the prior art (publication number: CN202121331210.0) records "a bearing grease injection device for deep groove ball bearings, comprising a frame, a material guide box, a discharge barrel, a guide rail, a bearing fixing fixture, and a material injection recovery device. The material guide box is located at the top of the frame, and the guide rail is installed between the frame and the displaceable discharge barrel. The bottom end of the material guide box is provided with a grease injection tray, and the bottom end of the grease injection tray is connected to a plurality of grease injection heads. The plurality of grease injection heads are arranged in a ring. The table of the frame is provided with a ring gear and a drive box fixedly connected to the table. When in use, the utility model injects grease into the interior of the bearing through the grease injection head. The bearing fixing fixture drives the bearing to rotate, causing the brush head to move on the surface of the roller. The rubber brush head causes the roller to rotate, evenly brushing the lubricating grease onto the roller surface, thereby achieving high grease injection efficiency and uniform grease distribution on the outer surface of the roller, and has certain practicality."

[0004] Although the bearing grease injection device used in the existing technology for deep groove ball bearings achieves a uniform grease injection effect, it still has some shortcomings: the existing deep groove ball bearing grease injection device is not convenient for greasing bearings with different outer diameters. Bearings with different outer diameters result in different grease injection positions, and it is more troublesome to manually adjust the grease injection position. Secondly, grease is prone to clump and harden in cold seasons, which makes the grease injection process prone to blockage. Utility Model Content
