Fig. 2 is a schematic top view of the high-strength socket integrated copper sleeve of fig. 1.
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 and fig. 2, which are schematic structural views of a high strength socket integrated copper sleeve according to the present invention. The high-strength sleeve and seat integrated copper sleeve comprises a bearing sleeve 10, a bearing seat 20 arranged on the outer side of the bearing sleeve 10, a plurality of reinforcing ribs 30 arranged on the outer side of the bearing sleeve 10 at intervals, and a plurality of graphite column groups 40 arranged on the bearing sleeve 10 in a multi-row mode. It is understood that the high-strength sleeve-seat integrated copper sleeve further includes other functional structures, such as fasteners, etc., which are well known to those skilled in the art and will not be described herein again.
The bearing sleeve 10 may be made of steel, bronze, or a copper alloy, and in this embodiment, the bearing sleeve 10 is made of a copper alloy. 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 graphite column set 40 should be limited 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 bearing seat 20 is fixedly arranged on the outer side of the bearing sleeve 10, and specifically, the bearing seat 20 and the bearing sleeve 10 are integrally formed. The axial direction of the bearing housing 20 is parallel to the axial direction of the bearing housing 10. The axial cross section of the bearing seat 20 is square. It is also conceivable that the bearing block 20 is provided with a through-hole or threaded hole for fixedly mounting the copper bush.
The reinforcing rib 30 is disposed on the outer side wall of the bearing housing 10, protrudes in the opposite direction of the center of the bearing housing 10, is used for reinforcing the strength of the bearing housing 10 itself and the installation strength of the copper housing, and the specific structure and the working principle thereof will be described with respect to the structure of the graphite column assembly 40.
The graphite column group 40 includes a plurality of rows and is disposed on an outer sidewall of the bearing housing 10. Each row of the graphite column group 40 includes a plurality of graphite columns, and in order to meet the self-lubricating requirement of the bearing housing 10 in the rotating process, an included angle between the arrangement direction of the plurality of graphite columns of each row and the central axis is 5 degrees to 10 degrees.

In fig. 1, a straight line in which the centers of the plurality of graphite columns are located is indicated by a broken line. Each of the graphite columns is cylindrical. The graphite column groups 40 and the reinforcing ribs 30 are alternately arranged at intervals. In order to facilitate the installation of the copper bush, the contour line of the reinforcing rib 30 in the cross section perpendicular to the axial direction of the bearing bush 10 is square, so the inner side wall of the installation device should also have a square groove coupled with the reinforcing rib 30, and during the installation, the installation device can be inserted by rotation, or the installation device can be divided into at least two parts to be fastened together and then connected with the bearing seat 20 by a fastening member. The reinforcing rib 30 is integrally formed with the bearing housing 10.
