Drawings
Embodiments of the invention are described below with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of a self-lubricating single ring bearing provided by the invention.
Detailed Description
Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Please refer to fig. 1, which is a schematic structural diagram of a self-lubricating single ring bearing according to the present invention. The self-lubricating single ring bearing comprises a bearing sleeve 10, a clamping ring 20 arranged on the bearing sleeve 10, a plurality of rows of first graphite column groups 30 arranged on the bearing sleeve 10 and a plurality of rows of second graphite column groups 40 arranged on the bearing sleeve 10. It is contemplated that the self-lubricating single ring bearing may include other functional features, such as skirts, mounting holes, etc., which are well known to those skilled in the art and will not be described herein.
The bearing housing 10 may be made of steel, bronze, copper alloy, ceramic, etc., and may have a cylindrical shape. The diameter of the bearing housing 10 and the thickness of the wall are designed according to the application field, and in this embodiment, the diameter and the thickness of the wall are not limited, so the parameter design of the first and second graphite column sets 30 and 40 should be defined by percentage rather than specific value. It is conceivable that the bearing housing 10 is a cylinder with a central axis 101, as indicated by the dash-dot line in fig. 1, due to the structural definition of the bearing. Usually the shaft or the bearing housing 10 rotates around the centre axis 101.
The snap ring 20 is used for fixing the bearing housing 10, that is, when the bearing housing 10 is installed, the snap ring 20 is clamped by a journal seat (not shown) and a bearing cover (not shown), so as to fix the bearing housing 20. The snap ring 20 may be a circular ring or a square ring. In this embodiment, the snap ring 20 is a circular ring, and is integrally formed with the bearing housing 10 and located at the middle of the bearing housing 10 along the axial direction thereof. The diameter of the snap ring 20 is larger than that of the snap ring, and the axial length is set according to actual needs.
The first and second graphite column sets 30, 40 are identical in function and nature and therefore will be described more simply when taken together. The first and second graphite column groups 30 and 40 respectively include a plurality of rows, and each row of the first and second graphite column groups 30 and 40 respectively includes a plurality of first and second graphite columns. It will be understood that the plurality of graphite columns of each row of the first graphite column set 30 have the same structural parameters and shapes, and the plurality of graphite columns of each row of the second graphite column set 40 have the same structural parameters and shapes. The first graphite column and the second graphite column are both cylindrical. In order to increase the lubricity and adapt to the corresponding bearing rotating speed, the included angle between the arrangement direction of the first graphite columns and the central axis 101 is between 30 and 35 degrees. The arrangement direction of the second graphite pillars is parallel to the arrangement direction of the first graphite pillars, i.e., the included angle between the arrangement direction of the second graphite pillars and the central axis 101 is also 30 to 35 degrees. Different included angles are suitable for different rotating speeds, and when the included angle is between 30 degrees and 35 degrees, the range of the applicable rotating speed is maximum. The first graphite column group 30 and the second graphite column group 40 are arranged at intervals, and the spacing distance between any adjacent first graphite column group 30 and second graphite column group 40 is equal, so that the first graphite column group 30 and the second graphite column group 40 are uniformly arranged on the bearing sleeve 10. The number of the graphite columns of the first graphite column group 30 in each row is greater than that of the graphite columns of the second graphite column group 40 in each row, and the graphite columns of the first graphite column group 30 in each row are arranged in the circumferential direction of the bearing sleeve 10 at intervals with the connecting line of the centers of the first graphite columns of the second graphite column group 40 in each row, namely, in the circumferential direction of the bearing sleeve 10, the centers of the first graphite columns and the centers of the second graphite columns are not on the same straight line, namely, the first graphite columns and the second graphite columns are arranged in a staggered mode. The first graphite column groups 30 are arranged around the central axis 101, that is, in a 360-degree rotation angle in the radial direction of the bearing housing 10, included angles between any two rows of the first graphite column groups 30 in the first graphite column groups 30 are equal. Because the spacing distance between any adjacent first and second graphite column groups 30, 40 is equal, the second graphite column groups 40 are also arranged around the central axis, and the included angles between any two rows of first graphite column groups 40 of the first graphite column groups 40 are equal. The diameter of the first graphite column is smaller than that of the second graphite column, so that the number of the graphite columns of the second graphite column group is smaller than that of the graphite columns of the first graphite column group. The first and second graphite column groups 30 and 40 may be disposed on both sides of the snap ring 20 according to the length of the bearing housing 10 on both sides of the snap ring 20.
Compared with the prior art, the self-lubricating single ring bearing provided by the invention has the first graphite column group 30 and the second graphite column group 40, and the self-lubricating performance of the single ring bearing is greatly improved through the arrangement mode of the first graphite column group 30 and the second graphite column group 40, the composition structure and the like, so that the performance of the self-lubricating single ring bearing is improved, and the phenomenon of blocking during use is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
