Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a bearing which is easy to lubricate. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The function of the inner ring is to cooperate with the shaft and rotate with the shaft. The function of the outer ring is to cooperate with the bearing seat and play a supporting role. The rolling elements are evenly distributed between the inner and outer rings with the help of the cage. The shape, size and number of the rolling elements directly affect the performance and life of the rolling bearing. The cage can evenly distribute the rolling elements, guide the rolling elements to rotate and play a lubricating role.

[0003] Existing public patent: CN202121373317.1 is a bearing that is easy to add lubricating oil. Through the cooperation between the fixed block, connecting rope, movable cover, sealing block, sealing gasket, threaded block, threaded rod, limit block, locating pin and manual turning handle in the disassembly and assembly mechanism, lubricating oil can be added to the inner side of the connecting mechanism, thereby improving the lubrication effect of the bearing, increasing the service life of the bearing, and improving the use efficiency and effect of the bearing.

DETAILED DESCRIPTION

[0040] Among them, a plurality of rolling steel balls 5 are slidably connected in the inner rotating groove 3, and the rolling steel balls 5 are adapted to the inner rotating groove 3;

[0041] The rolling steel ball 5 is located between the bearing outer ring 1 and the bearing inner ring 2;

[0042] There are two first sealing rings 6 slidably connected between the bearing outer ring 1 and the bearing inner ring 2, the outer surface of the first sealing ring 6 is slidably connected to the inner wall of the bearing outer ring 1, and the inner wall of the first sealing ring 6 is slidably connected to the outer surface of the bearing inner ring 2;

[0043] Among them, an oil filling mechanism is arranged on the first sealing ring 6, and the oil filling mechanism includes a second sealing ring 7, a countersunk hole 8, a countersunk bolt 9, a threaded hole 10, a rotating groove 11, a sealing cover 4, a mounting groove 12, a mounting tube 13, a spring 14 and a mounting block 15.

[0044] Furthermore, the two rotation grooves 11 are both on the front and rear surfaces of the bearing outer ring 1 and the bearing inner ring 2, and the rotation grooves 11 extend out of the inner wall of the bearing outer ring 1, and the rotation grooves 11 also extend out of the outer surface of the bearing inner ring 2;

[0045] Among them, two second sealing rings 7 are rotatably sleeved in the rotating grooves 11 on the front and rear sides;

[0046] A plurality of countersunk holes 8 are provided on the opposite side surfaces of the two second sealing rings 7 .

[0047] Further, a plurality of countersunk bolts 9 are slidably sleeved in the countersunk holes 8;

[0048] Among them, a plurality of threaded holes 10 are provided on the front and rear surfaces of the bearing outer ring 1;

[0049] The countersunk bolt 9 is threadedly connected with the threaded hole 10 through the countersunk hole 8 .

[0050] Furthermore, two mounting grooves 12 are provided on the two opposite side surfaces of the two second sealing rings 7;

[0051] The two mounting grooves 12 extend relatively from the adjacent outer surfaces of the two first sealing rings 6;

[0052] The two mounting tubes 13 are fixedly sleeved in the two mounting grooves 12 .

[0053] Furthermore, two opposite ends of the two mounting tubes 13 extend out from two opposite outer surfaces of the second sealing rings 7;

[0054] The two sealing covers 4 are slidably mounted on the outer surfaces of the two mounting tubes 13;

[0055] The two mounting blocks 15 are fixedly connected to the outer surfaces of the two sealing covers 4 .

[0056] Furthermore, four springs 14 are fixedly connected to the opposite side surfaces of the two second sealing rings 7;

[0057] Among them, one end of the four springs 14 away from the second sealing ring 7 is fixedly connected to four mounting blocks 15;

[0058] The two first sealing rings 6 are fixedly connected to the second sealing ring 7 .

[0059] Furthermore, in this solution, a sealing ring is arranged between the first sealing ring 6 and the bearing outer ring 1 and the bearing inner ring 2, a seal is also arranged between the bearing outer ring 1 and the bearing inner ring 2 and the second sealing ring 7, and a sealing ring is also arranged between the sealing cover 4 and the mounting tube 13.

[0060] Furthermore, in this solution, the second sealing ring 7 is rotatably connected to the bearing outer ring 1 and the bearing inner ring 2 through the rotating groove 11, thereby increasing the contact area between the second sealing ring 7 and the bearing outer ring 1 and the bearing inner ring 2, thereby achieving a better sealing effect.

[0061] Furthermore, in the present solution, the first sealing ring 6 does not contact the rolling steel ball 5, and the first sealing ring 6 is located between the bearing outer ring 1 and the bearing inner ring 2. Therefore, when the sealing cover 4 is pulled out, the sealing cover 4 moves in a direction away from the second sealing ring 7. During the movement of the sealing cover 4, the spring 14 is stretched, causing the spring 14 to be stretched and deformed. When the sealing cover 4 moves to a point where it is no longer in contact with the mounting tube 13, the sealing cover 4 does not seal the mounting tube 13. At this time, lubricating oil can be injected or filled into the mounting tube 13. The lubricating oil can flow into the inner rotating groove 3 through the mounting groove 12, thereby improving the lubrication effect between the rolling steel ball 5 and the bearing outer ring 1 and the bearing inner ring 2, reducing friction, and thereby ensuring the service life of the bearing. The lubricating oil can be injected or filled by pulling out the sealing cover 4 without disassembling the bearing. The operation is simple, thereby improving the lubrication efficiency of the bearing.

[0062] Furthermore, in the present solution, the spring 14 has a strong elastic force, so that the spring 14 will not be deformed by the centrifugal force during the rotation process, thereby ensuring the sealing effect of the mounting tube 13. After the lubrication of the bearing is completed, the pulling of the sealing cover 4 is released, and the sealing cover 4 is driven to re-seal the mounting tube 13 under the action of the released elastic force of the spring 14, thereby avoiding the leakage of lubricating oil, and the operation is simple, thereby increasing the practicality of the bearing.

[0063] Working principle: When the device is in use, the first sealing ring 6 does not contact the rolling steel ball 5, and the first sealing ring 6 is located between the bearing outer ring 1 and the bearing inner ring 2. Therefore, when the sealing cover 4 is pulled out, the sealing cover 4 moves in the direction away from the second sealing ring 7. During the movement of the sealing cover 4, the spring 14 is stretched, causing the spring 14 to be stretched and deformed. Then, when the sealing cover 4 moves to a point where it is not in contact with the mounting tube 13, the sealing cover 4 does not seal the mounting tube 13. Then, at this time, lubricating oil can be injected or filled into the mounting tube 13. The lubricating oil can flow into the inner rotating groove 3 through the mounting groove 12, thereby improving the lubrication effect between the rolling steel ball 5 and the bearing outer ring 1 and the bearing inner ring 2, reducing friction, and thereby ensuring the service life of the bearing. The lubricating oil can be injected or filled by pulling out the sealing cover 4 without disassembling the bearing. The operation is simple, thereby improving the lubrication efficiency of the bearing.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
