DETAILED DESCRIPTION

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] This embodiment provides a mechanical bearing that is easy to oil, and the bearing is used to support a mechanical rotating body and reduce its friction coefficient during movement. The bearing can be easily oiled when in use to avoid wear of the mechanical bearing and ensure normal use of the mechanical bearing.

[0027] See also Figures 1 to 8 A mechanical bearing that is easy to oil, includes an outer ring 1, an inner ring 2 is arranged inside the outer ring 1, a group of balls 3 in a circumferential array are arranged between the outer ring 1 and the inner ring 2, and grooves matched with the balls 3 are opened on the inner wall of the outer ring 1 and the outer surface of the inner ring 2. When the bearing is in use, a group of balls 3 are installed between the outer ring 1 and the inner ring 2 by interference fit, so that the inner ring 2 can make a rotational motion inside the outer ring 1.

[0028] The front and back sides of the outer ring 1 are both provided with a placement groove 1 4 , the front and back sides of the inner ring 2 are both provided with a placement groove 2 5 , and the outer surface of the outer ring 1 is provided with two symmetrical dust covers 6 , and the dust covers 6 are located between the placement groove 1 4 and the placement groove 2 5 .

[0029] The depth of placement groove 1 4 and the depth of placement groove 2 5 are the same as the thickness of dust cover 6. After placing dust cover 6 between placement groove 1 4 and placement groove 2 5, the outer surface of dust cover 6 can be flush with the surface of outer ring 1 and the surface of inner ring 2. Installing dust cover 6 between placement groove 1 4 and placement groove 2 5 can prevent dust from entering between outer ring 1 and inner ring 2 and causing damage to the mechanical bearing.

[0030] Both dust covers 6 are connected to the outer ring 1 through a set of clamping components 7, and the clamping components 7 include a clamping frame 701 and a clamping column 702. The clamping frame 701 is fixedly connected to the inner wall of the outer ring 1, and the clamping column 702 is fixedly connected to the outer surface of the dust cover 6. The end of the clamping column 702 away from the dust cover 6 is located inside the clamping frame 701.

[0031] When installing the dust cover 6, when the dust cover 6 is placed between the placement groove 1 4 and the placement groove 2 5, the clamping column 702 installed on the outer surface of the dust cover 6 can be inserted into the interior of the clamping frame 701, which is convenient for the subsequent installation of the dust cover 6.

[0032] Two symmetrical slots 703 are formed on the outer surface of the clamping column 702, and two symmetrical cylinders 704 are fixedly embedded on the outer surface of the clamping frame 701. The inner walls of the two cylinders 704 are slidably connected with slides 705, which can slide on the inner walls of the cylinders 704 to guide the slides 705.

[0033] A clamping rod 706 is installed on the side where the two cylinders 704 are close to each other, and the clamping rod 706 is clamped with the inner wall of the slot 703. A cylinder 704 is installed on the side where the two slides 705 are away from each other, and the end of the cylinder 704 away from the slide 705 is connected to the inner wall of the cylinder 704.

[0034] When the card column 702 is inserted into the interior of the card frame 701, the end part of the card column 702 can push the two card rods 706 away from each other, and the two springs 707 can be compressed. When the card column 702 moves to the position corresponding to the card slot 703 and the card rod 706, the elastic force of the spring 1 707 can make the card rod 706 inserted into the interior of the card slot 703, and the card column 702 can be limited, so that the dust cover 6 can be installed conveniently.

[0035] An oil filling assembly 8 is installed on the outer surface of the two dust covers 6, and the oil filling assembly 8 includes an oil filling cylinder 801 fixedly embedded in the outer surface of the dust cover 6, and a group of oil filling holes 802 are opened on the inner wall of the oil filling cylinder 801. A connecting rod 803 is slidably connected to the inner wall of the oil filling cylinder 801, and a sealing plate 804 is installed at one end of the connecting rod 803, and the outer surface of the sealing plate 804 is in contact with the outer surface of the oil filling cylinder 801.

[0036] The sealing plate 804 contacts the oil filling cylinder 801 to seal the oil filling hole 802, thereby preventing dust and impurities from entering between the outer ring 1 and the inner ring 2 through the oil filling hole 802. When the connecting rod 803 slides on the inner wall of the oil filling cylinder 801, it can drive the sealing plate 804 to move, and can guide and limit the sealing plate 804.

[0037] A push plate 805 is installed at one end of the connecting rod 803 away from the sealing plate 804, and a spring 806 is installed between the push plate 805 and the inner wall of the oil filling cylinder 801. The spring 806 is sleeved on the outer surface of the connecting rod 803, and the spring 806 does not contact the connecting rod 803.

[0038] Insert the oil filling tube into the oil filling cylinder 801. One end of the oil filling tube can push the push plate 805 to move inside the oil filling cylinder 801, so that the connecting rod 803 can drive the sealing plate 804 to move, compress the spring 2 806, and release the seal of the oil filling hole 802. The oil inside the oil filling tube can enter between the outer ring 1 and the inner ring 2 through the oil filling hole 802, so that the mechanical bearing can be easily oiled.

[0039] An oil groove 1 9 is provided on the inner wall of the outer ring 1, and an oil groove 2 10 is provided on the outer surface of the inner ring 2. By utilizing the oil groove 1 9 and the oil groove 2 10, the lubricating oil injected between the outer ring 1 and the inner ring 2 can be temporarily stored in the oil groove 1 9 and the oil groove 2 10, thereby ensuring the lubrication of the ball 3 during rotation and facilitating the use of the bearing.

[0040] Working principle: When the mechanical bearing is in use, the outer ring 1 is placed inside the bearing seat for fixation, and one end of the mechanical rotating body to be supported is installed inside the inner ring 2. When the mechanical rotating body rotates, the inner ring 2 can rotate inside the outer ring 1, so as to support the mechanical rotating body. The dust cover 6 is placed on the outer surface of the outer ring 1, so that the dust cover 6 is located between the placement groove 1 4 and the placement groove 2 5, and the outer surface of the dust cover 6 is installed with a clamping column 702 which is inserted into the inside of the clamping frame 701. When the clamping column 702 is inserted into the inside of the clamping frame 701, the end part of the clamping column 702 can push the two clamping rods 706 away from each other, so as to compress the two springs 1 707. When the clamping column 702 moves to the position corresponding to the clamping groove 703 and the clamping rod 706, the spring 1 707 is compressed. The elastic force of 707 can make the clamping rod 706 inserted into the interior of the clamping groove 703 and limit the clamping column 702, so as to facilitate the installation of the dust cover 6 and prevent dust and impurities from entering between the outer ring 1 and the inner ring 2. When it is necessary to inject oil between the outer ring 1 and the inner ring 2, it is only necessary to insert the oil filling tube into the interior of the oil filling cylinder 801. One end of the oil filling tube can push the push plate 805 to move inside the oil filling cylinder 801, so that the connecting rod 803 can drive the sealing plate 804 to move, compress the spring 806, and release the seal of the oil filling hole 802. The oil inside the oil filling tube can enter between the outer ring 1 and the inner ring 2 through the oil filling hole 802, which can facilitate the oiling of the mechanical bearing and ensure the normal use of the mechanical bearing.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
