Description

Technical Field

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

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. In other words, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during transmission.

[0003] During use, although the existing bearings can support the mechanical rotating body, it is not convenient to install the dust cover, which results in a lot of time spent on assembly. It is also not convenient to protect the dust cover, which causes a lot of friction when the bearing rotates, causing the dust cover to overheat and be damaged, thereby reducing the service life of the equipment. For this reason, a bearing with a dust cover is introduced. Utility Model Content

[0008] As a preferred technical solution of the present invention: the fixed shell is fixedly assembled with the inner wall of the placement groove, and the spring is fixedly assembled with the inner wall of the fixed shell.

[0009] As a preferred technical solution of the present invention: the placement groove is provided on the outer wall of the bearing inner ring, and the fillet is matched with the inner wall of the positioning groove.

[0010] As a preferred technical solution of the present invention: there are several placement blocks and clamping assemblies, and the several placement blocks and clamping assemblies are respectively located on the inner walls of the bearing outer ring and the bearing inner ring.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When the outer ring and the inner ring of the bearing with dust covers rotate, the dust covers 1 and 2 are driven to rotate. The limit block fixedly assembled on the outer wall of the dust cover 2 and the rotating ball rotating inside the limit block rotate on the inner wall of the arc sleeve rod, so that the friction generated by the dust covers 1 and 2 during rotation is reduced, thereby preventing the dust covers 1 and 2 from being damaged due to frictional heat during rotation, thereby protecting the dust covers 1 and 2.

[0013] 2. For the bearing with dust covers, when installing the dust cover 1 and the dust cover 2, the staff picks up the dust cover 1 and the placement block and places them on the inner wall of the placement groove, so that when the placement block is placed on the inner wall of the placement groove, it will press the rounded corner of the outer wall of the positioning block. After the positioning block is subjected to pressure, it will drive the pressure plate to rotate on the inner wall of the moving block, so that when the pressure plate rotates, it will drive the moving block to move on the outer wall of the fixed rod. The moving block will squeeze the spring during movement, and when the placement block is placed at the end of the placement groove, the positioning groove will cancel the limit of the positioning block, so that the elastic potential energy of the spring is released, and the positioning block is driven by the spring to move toward the inner wall of the positioning groove to clamp and fix the two sides of the placement block, thereby facilitating the installation of the dust cover 1 and the dust cover 2.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 - Figure 6 A bearing with a dust cover includes a bearing outer ring 1, a bearing inner ring 2 is provided on the inner wall of the bearing outer ring 1, a placement groove 5 is opened on the outer wall of the bearing outer ring 1, a clamping component 9 is provided on the inner wall of the placement groove 5, a dust cover 1 3 is provided on the outer wall of the bearing outer ring 1, a dust cover 2 4 is provided on the outer wall of the dust cover 1 3, a placement block 8 is fixedly assembled on one end of the dust cover 1 close to the bearing outer ring 1, and a positioning groove 10 is opened on the outer wall of the placement block 8.

[0024] In the above structure, the retaining frame 6 is used to limit the ball 7 to prevent the ball 7 from falling off from between the bearing outer ring 1 and the bearing inner ring 2 during rotation. The ball 7 is used to reduce the friction between the bearing outer ring 1 and the bearing inner ring 2 to prevent the bearing outer ring 1 and the bearing inner ring 2 from being consumed excessively during rotation.

[0025] In a preferred embodiment: the inner wall of the bearing outer ring 1 is fixedly assembled with a retaining frame 6, the inner wall of the retaining frame 6 is rotatably connected to the ball 7, the outer wall of the dust cover 1 3 is fixedly assembled with an arc-shaped sleeve rod 11, the outer wall of the dust cover 2 4 is fixedly assembled with a limit block 12, and the inner wall of the limit block 12 is rotatably connected to the rotating ball 13.

[0026] In the above structure, when the bearing outer ring 1 and the bearing inner ring 2 rotate, the dust cover 1 3 and the dust cover 2 4 will be driven to rotate accordingly. The limit block 12 fixedly installed on the outer wall of the dust cover 2 4 and the rotating ball 13 rotating inside the limit block 12 rotate on the inner wall of the arc sleeve 11, thereby reducing the friction generated by the dust cover 1 3 and the dust cover 2 4 during the rotation process, avoiding the heat generated by friction that causes damage to the dust cover 1 3 and the dust cover 2 4, and thus achieving effective protection for the dust cover 1 3 and the dust cover 2 4.

[0027] In a preferred embodiment: the clamping assembly 9 includes a fixed shell 901, the inner wall of the fixed shell 901 is fixedly equipped with a fixed rod 902, the outer wall of the fixed rod 902 is slidably connected to a moving block 904, the outer wall of the moving block 904 is fixedly equipped with a spring 903, the inner wall of the moving block 904 is rotatably connected to one end of a pressure plate 905, the other end of the pressure plate 905 is fixedly equipped with a positioning block 906, and the outer wall of the positioning block 906 is provided with a rounded corner 907.

[0028] When the locking plate 905 is pressed, the pressure plate 905 is driven to rotate in the inner wall of the movable block 904. As the pressure plate 905 rotates, the movable block 904 moves on the outer wall fixing rod 902, thereby squeezing the spring 903. When the placement block 8 is placed at the end of the placement slot 5, the locking slot 10 cancels the limit of the locking block 906, and the elastic potential energy of the spring 903 is released. Subsequently, the spring 903 pushes the locking block 906 to move toward the inner wall of the locking slot 10, thereby clamping and fixing the two sides of the placement block 8, thereby facilitating the installation of the dust cover 1 3 and the dust cover 2 4.

[0029] In a preferred embodiment, the fixed shell 901 is fixedly assembled with the inner wall of the placement groove 5 , and the spring 903 is fixedly assembled with the inner wall of the fixed shell 901 .

[0030] In the above structure, the clamping assembly 9 is limited by placing the groove 5, so that the clamping assembly 9 is more stable when placed and will not fall off. The spring 903 is limited by the fixed shell 901 and the movable block 904, so that the spring 903 will not fall off when the elastic potential energy of the spring 903 is released.

[0031] In a preferred embodiment, the placement groove 5 is opened on the outer wall of the bearing inner ring 2 , and the rounded corner 907 is matched with the inner wall of the locking groove 10 .

[0032] In the above structure, the placement grooves 5 are respectively opened on the outer walls of the bearing outer ring 1 and the bearing inner ring 2, so that the placement grooves 5 can limit the dust cover 1 3 and the dust cover 2 4. When the rounded corners 907 are placed on the inner wall of the positioning groove 10, the placement block 8 can be fixed, and the dust cover 1 3 and the dust cover 2 4 can be fixed.

[0033] In a preferred embodiment, there are several placement blocks 8 and clamping assemblies 9, and the several placement blocks 8 and clamping assemblies 9 are respectively located on the inner walls of the bearing outer ring 1 and the bearing inner ring 2.

[0034] In the above structure, the dust cover 1 3 and the dust cover 2 4 are fixed by a plurality of placement blocks 8 and clamping assemblies 9, so that the dust cover 1 3 and the dust cover 2 4 are more stable when placed, and the dust cover 1 3 and the dust cover 2 4 are prevented from falling off when rotating.

[0035] Working principle: When the outer ring 1 and the inner ring 2 of the bearing rotate, the dust cover 1 3 and the dust cover 2 4 will be driven to rotate synchronously. The limit block 12 fixedly assembled on the outer wall of the dust cover 2 4 and the rotating ball 13 rotating inside the limit block 12 rotate on the inner wall of the arc sleeve 11, effectively reducing the friction generated by the dust cover 1 3 and the dust cover 2 4 during the rotation process, thereby avoiding the heat generated by friction that causes damage to the dust cover 1 3 and the dust cover 2 4, and realizing their protection. In the process of installing the dust cover 1 3 and the dust cover 2 4, the staff will pick up the dust cover 1 3 and the placement block 8 and place them on the inner wall of the placement slot 5. At this time, the placement block 8 will engage the positioning block 9 06, the rounded corner 907 of the outer wall of the latch 906 applies pressure. After the latch block 906 is under pressure, it will drive the pressure plate 905 to rotate on the inner wall of the moving block 904, and the rotation of the pressure plate 905 will drive the moving block 904 to move on the outer wall of the fixed rod 902. As the moving block 904 moves, it will squeeze the spring 903. When the placement block 8 is placed at the end of the placement slot 5, the latch slot 10 cancels the limit on the latch block 906, so that the elastic potential energy of the spring 903 is released. Through the action of the spring 903, the latch block 906 will move toward the inner wall of the latch slot 10, thereby clamping and fixing the two sides of the placement block 8, making it easy to install the dust cover 1 3 and the dust cover 2 4.
