Embodiment 1

[0036] like Figure 1-2 As shown, the present invention provides a technical solution: a special reinforced bearing for self-lubricating high-temperature guide rails, including a bearing outer ring 1 and a reinforced inner ring 2, the reinforced inner ring 2 is located inside the bearing outer ring 1, and the reinforced inner ring 2 and the bearing Rollers 3 are arranged between the outer rings 1, and composite protectors 4 are arranged on the periphery of the rollers 3. The highest point of the synapse 11 is located on the center line of the bearing outer ring 1, and an arc-shaped groove is opened inside the bearing outer ring 1, and the upper half of the roller 3 is located inside the arc-shaped groove.

[0037] In this embodiment, the cylindrical surface of the outer diameter of the traditional bearing is changed to an arc-shaped synapse 11 in the state of a large arc surface, so that the contact between the outer ring of the bearing 1 and the guide rail changes from a line...

Embodiment 2

[0039] like image 3 and Figure 5 As shown, the reinforced inner ring 2 includes a closed outer layer 21 and a reinforced inner layer 22, the closed outer layer 21 is covered on the outer wall of the reinforced inner layer 22, and a dispersion panel 23 is arranged between the closed outer layer 21 and the reinforced inner layer 22. The inner wall of the protector 4 is overlapped on the outer wall of the reinforced inner layer 22, the dispersion panel 23 includes an independent support net 231, a receiving groove 232 and an expansion through hole 233, and the bottom of the independent support net 231 is installed on the outer wall of the reinforced inner layer 22 , the expansion through hole 233 is located at the center of the independent support network 231 , and the expansion through hole 233 is located at the edge of the independent support network 231 .

[0040]In this embodiment, the closed outer layer 21 and the reinforced inner layer 22 together form the reinforced inn...

Embodiment 3

[0042] like Figure 4 and 6 As shown, the composite protector 4 includes a restricting outer ring 41, a docking inner ring 42 and a positioning splint 43, the number of the restricting outer ring 41, the docking inner ring 42 and the positioning splint 43 are two, and one side of the docking inner ring 42 is connected On one side of limiting the outer ring 41, the positioning splint 43 is installed on the other side of the docking inner ring 42, and the other side of the positioning splint 43 is connected with another positioning splint 43, and the roller 3 is positioned at the inside of the positioning splint 43. Clamping plate 43 comprises fixed inner core 431, partition shell 432 and positioning ring 433, and one end of fixed inner core 431 is connected on the inner wall of positioning ring 433, and one end of partition shell 432 is connected at the edge of positioning ring 433, and the fixed inner The core 431 is located inside the partition shell 432, and the intersectio...

Abstract

The invention provides a self-lubricating reinforced bearing special for a high-temperature guide rail, and relates to the technical field of automobile accessories, the self-lubricating reinforced bearing comprises a bearing outer ring and a reinforced inner ring, the reinforced inner ring is located in the bearing outer ring, a roller is arranged between the reinforced inner ring and the bearing outer ring, and a composite protector is arranged on the periphery of the roller. And the roller is positioned in the composite protector. The cylindrical surface of the outer diameter of the bearing is changed into the large-radian curved surface, so that the contact between the outer ring of the bearing and the guide rail is changed into point contact from line contact, the operation stability and impurity adhesion resistance of the bearing are improved, the guide rail bearing operates stably on a coating line, the vibration and shaking phenomena do not exist, and the bearing can work normally at high temperature; the bearing outer ring is in point contact with the guide rail, operation is stable, deformation and inclination of the guide rail rod can be adapted, bearing lubrication can resist paint mist, lubrication is good, and the phenomenon of lubrication clamping stagnation is avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a special reinforced bearing for self-lubricating high-temperature guide rails. Background technique [0002] The existing guide rail bearings of automobile painting lines must meet the following technical level requirements when they are working: 1. The guide rail rods for suspending automobiles run smoothly; 2. The guide rail bearings can work at high temperatures and can withstand high temperature environments above 300 degrees Celsius; 3 , Bearing lubrication can work normally under high-temperature paint mist, without paint mist reaction, and not affected by paint mist. [0003] The existing standard guide rail bearings cannot meet the above requirements well during use. There are phenomena such as short bearing time, rapid failure, and frequent bearing replacement. At present, the outer ring of the bearing is a cylindrical surface, which is easy to adhere to impurities o...
