Description

Technical Field

[0001] The utility model relates to the technical field of linear bearings, in particular to an elongated flange automatic centering linear bearing. Background Art

[0002] Linear bearings are bearings for operating mechanisms and are used in transmission mechanisms. They are important components of motion mechanisms. The housing of general linear bearings is deep, making positioning difficult. The outer diameter of the linear bearing and the housing are transition fits, while the operating transmission shaft and the inner circle are interference fits. In addition to reciprocating linear motion, the operating shaft also rotates at a certain angle and requires a certain load control. Although general linear bearings can be greased during installation, it is not convenient to add grease during the subsequent use cycle. Therefore, under high load or after long-term operation, linear bearings will wear due to lack of lubrication. Therefore, linear bearings need to have self-lubricating function and corrosion resistance.

[0003] In the Chinese patent with publication number CN219510009U, a linear bearing is disclosed, including an outer ring, a rolling element, a cage and a retaining ring, the rolling element is installed on the cage, the retaining ring is installed on the outer side of the cage, and the retaining ring is arranged on the inner side of the outer ring. A square groove is arranged on the outer ring, and the linear bearing is axially positioned by the square groove, and the linear bearing prevents the outer ring from rotating circumferentially by the square groove. The utility model can make the linear bearing have positioning ability and prevent the outer ring from rotating under special working conditions by arranging the square groove on the outer ring, and by using ceramic balls as rolling elements, excessive wear between the raceway and the rolling elements is avoided, and the continuous service life of the linear bearing under non-lubricated conditions is improved; by using a variety of new materials to process the outer ring, cage and retaining ring of the linear bearing, the corrosion resistance requirements of the linear bearing are met.

[0004] The above device uses ceramic balls as rolling elements to avoid excessive wear between the raceways and the rolling elements, thereby increasing the continuous service life of the linear bearing under non-lubricated conditions. However, in the prior art, the load-bearing and life of the linear bearing are limited. Since it does not have a mounting flange, it is inconvenient to disassemble and has poor stability.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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 of the embodiments.

[0021] Reference Figures 1 to 3 , an extended flange automatic self-aligning linear bearing, comprising a first housing 1 and a second housing 2, a retaining frame 3 is installed on one side of the first housing 1, a steel ball pad 6 is arranged on the outer periphery of the first housing 1, a plurality of grooves 4 are opened on the inner side of the steel ball pad 6, and a plurality of steel balls 5 are arranged in the grooves 4;

[0022] A receiving groove 7 is provided on one side of the second shell 2 and passes through the second shell 2 . A mounting flange 8 is provided on the other side of the second shell 2 . The first shell 1 is installed in the receiving groove 7 . Limiting members 9 are provided on both sides of the receiving groove 7 .

[0023] When the device is in use, the retaining frame 3 and the plurality of steel balls 5 can be installed in the first shell 1, and the first shell 1 can be installed in the second shell 2. The first shell 1 can be restricted in the receiving groove 7 by two limit members 9, and the mounting flange 8 can be arranged on one side of the second shell 2 for convenient installation and disassembly, so that the device has a larger load-bearing capacity, a longer service life, and better installation fixity, which solves the problem in the prior art that the device is inconvenient to disassemble and has poor stability due to the lack of a mounting flange.

[0024] Furthermore, a sealing gasket 10 is provided on one side of the retaining frame 3 , and the sealing gasket 10 is connected to the first shell 1 . The provided sealing gasket 10 can prevent the steel ball 5 in the groove 4 from moving out.

[0025] Furthermore, the first shell 1 and the second shell 2 are both cylindrical.

[0026] Furthermore, the material of the first shell 1 is plastic, and the material of the second shell 2 is aluminum. By setting the material of the first shell 1 to plastic, the cost of the device is reduced, and by setting the material of the second shell 2 to aluminum, it can be recycled indefinitely, which can save energy.

[0027] Furthermore, the limiting member 9 is a retaining ring, and the retaining ring is connected to one side of the second shell 2 by bolts. The setting of the retaining ring can limit the first shell 1 in the accommodating groove 7 to prevent the first shell 1 in the second shell 2 from moving out, thereby limiting the first shell 1.

[0028] Furthermore, the second housing 2 and the mounting flange 8 are integrally arranged. By integrally arranging the second housing 2 and the mounting flange 8, the bearing can bear a larger load and have better installation fixation.
