Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to fig. 2, which are schematic structural views of the novel spherical plain bearing provided by the present invention. The novel joint bearing comprises a spherical inner ring 1 and a spherical hole outer ring 10 sleeved on the outer side of the spherical inner ring 1. The novel spherical plain bearing also comprises other functional modules, such as assembly components and the like, which are known to those skilled in the art and will not be described in detail herein.
The ball hole outer ring 10 comprises an outer ring main body 11, at least three elastic sheets 12 and grooves 13 which are arranged on the outer side wall of the outer ring main body 11 at intervals, an annular base 14 arranged at one end of the outer ring main body 11, and a plurality of through holes 15 arranged on the annular base 14. In addition, the spherical inner ring 1 and the spherical hole outer ring 10 are both made of plastic, so that the spherical inner ring 1 and the spherical hole outer ring 10 are both elastic.
The outer ring main body 11 is used for installing the spherical inner ring 1, so that the spherical inner ring 1 can perform swinging motion and tilting motion, and the connection mode between the spherical inner ring 1 and the outer ring main body 11 is the prior art and is not repeated again
Each spring 12 includes a connecting member 121 disposed on an outer side wall of the outer ring main body 11, and a spring main body 122 disposed on the connecting member 121. The spring plates 12 and the grooves 13 are arranged in a surrounding mode by taking the central shaft of the outer ring main body as a circle center, each spring plate 12 and each groove 13 are arranged in the axial direction of the outer ring main body, and the outer contour of each spring plate 12 is in a Y shape on the section perpendicular to the central shaft of the outer ring main body 11.
The connecting member 121 is connected to the outer ring main body 11, so that the outer ring main body 11 and the spring plate 12 are connected as a whole. The outer ring main body 11 and the elastic sheet 12 are integrally formed, so that the surface quality between the outer ring main body 11 and the elastic sheet 20 is high, the forming precision is high, and the service lives of the outer ring main body 11 and the elastic sheet 12 are prolonged.
On the cross section perpendicular to the central axis of the outer ring main body 11, the outer contours of the elastic sheet main body 122 are all arc-shaped, and the center of the arc-shaped circle is arranged on one side back to the outer ring main body. When the spring main body is in a free state, when the connection point between the spring main body 122 and the connecting piece 121 is connected to the ends of the two sides along the arc of the spring main body 122, the distance between the spring main body 122 and the central axis of the outer ring main body 11 gradually increases, so that the ball hole outer ring 10 is installed in the seat holes with different dimensional tolerances and has pressing force to keep stable. In addition, when the leaf spring main body 122 is in a free state, the distance between the connection point between the leaf spring main body 122 and the connection member 121 and the central axis of the outer ring main body 11 is equal to the outer diameter of the outer ring main body 11, so that the ball hole outer ring 10 is stable when being installed. It is conceivable that, when the elastic sheet main body 122 is inserted into the seat holes of other parts, both ends of each elastic sheet main body 122 far from the connecting piece 121 are bent toward the side close to the central axis of the outer ring main body 11, and under the support of the connecting piece 121, the distance between the connecting point between the elastic sheet main body 122 and the connecting piece 121 and the central axis of the outer ring main body 11 is always equal to the outer diameter of the outer ring main body 11, so that when the elastic sheet main body 122 is inserted into the seat holes of other parts, the outer side walls of the elastic sheet main body 122 and the outer ring main body 11 are abutted against the side wall of the seat hole, so as to increase the stability of the ball hole outer ring 10 and prevent the ball hole outer ring 10 from shaking.
Since the ball hole outer ring 10 is made of plastic, it is conceivable that the whole elastic sheet 12 is also provided with elasticity as an elastic mechanism, when the sizes of the seat holes are different, the elastic sheet 12 can be freely adjusted along with the sizes of the seat holes, and when the seat holes are pressed in, the elastic sheet 12 can compensate for the deviation of the seat holes by utilizing the elasticity of the elastic sheet 12. Each of the spring main bodies 122 is far away from one end of the annular base 14, and one end of the outer ring main body 11 far away from the annular base 14 is provided with a chamfer, so that the ball hole outer ring 10 is in a seat hole of another part. The distance between any two adjacent spring pieces 12 and the distance between any two adjacent grooves 13 are equal, so that the spring pieces 12 and the grooves 13 are uniformly arranged on the outer side wall of the outer ring main body 11, and further, the stress of each position of the ball hole outer ring 10 is uniform when the ball hole outer ring is installed, so that the position of the ball hole outer ring 10 is stable.
Each groove 13 is provided with one spring plate 12. On the cross section perpendicular to the central axis of the outer ring main body 11, the length of the spring main body 122 is smaller than that of the groove 13, so that when the spring main body 122 is stressed, two sides of the spring main body 122 are bent and accommodated in the groove 13. When the outer ring 10 of the ball hole is mounted on the seat hole of other parts, the edge of the seat hole is accommodated in the groove 13, the groove 13 plays a positioning role and prevents the outer ring main body 11 from rotating in the seat hole, so that the position of the outer ring 10 of the ball hole is stable. In addition, the elastic sheet 12 is matched with the groove 13, so that the edges of seat holes of other parts are clamped between the elastic sheet 12 and the groove 13, and the stable installation of the outer ring main body 11 is ensured.
The annular seat 14 is used to regulate the position of the outer ring main body 11, and when the outer ring main body 11 is mounted in a seat hole of another component, the annular seat 14 abuts against the seat of the other component, thereby regulating the position of the entire ball hole outer ring 10 and stabilizing the position of the ball hole outer ring 10.
Each through hole 15 is communicated with one groove 13, the ball hole outer ring 10 is mounted on seat holes of other parts, the edge of the seat hole can be inserted into the through hole 15 along the groove 13, and the stability of the ball hole outer ring 10 is further improved.
When the ball hole outer ring 10 is installed, the elastic sheet 12 is inserted into a seat hole of another part to limit the position of the outer ring main body 11. The two side edges of the elastic sheet main body 121 clamp the edges of the seat hole of the part between the elastic sheet main body 121 and the outer ring main body 11, so that the axial height of the elastic sheet 12 limits the axial position of the outer ring main body 11, and the elastic sheet main body 122 limits the radial position of the outer ring main body 11, thereby having low precision requirement on the seat hole of the part. In addition, when the outer ball hole ring 10 is pressed into seat holes of other parts, the elastic sheet 12 can compensate for deviation of the seat holes by utilizing elasticity of the elastic sheet 12, so that the requirement of the elastic sheet 12 on the accuracy of the seat holes is not very high, the position of the outer ball hole ring 10 in the seat holes is stable, and noise generated by collision between the outer ball hole ring 10 and the seat holes of other parts is avoided when the inner ball ring 1 and the outer ball hole ring 10 move.
Compared with the prior art, the novel joint bearing provided by the invention is limited in the seat holes of other parts by arranging at least three elastic sheets 12 on the outer ring main body 11. Each spring 12 includes a connecting member 121 disposed on an outer side wall of the outer ring main body 11, and a spring main body 122 disposed on the connecting member 121. The axial height of the elastic sheet 12 limits the axial position of the outer ring main body 11, the elastic sheet main body 122 limits the radial position of the outer ring main body 11, so that the accuracy requirement on the seat hole of a part is not very high, and when the ball hole outer ring 10 is pressed into the seat holes of other parts, the elastic sheet 12 can compensate the deviation of the seat hole by utilizing the elasticity of the elastic sheet 12, when the sizes of the seat holes are different, the elastic sheet 12 can be freely adjusted along with the sizes of the seat holes, namely when the outer ring main body 11 is pressed into the seat hole, the elastic sheet 12 can compensate the deviation of the seat hole by utilizing the elasticity of the elastic sheet 12, so that the accuracy requirement of the elastic sheet 12 on the seat hole is not very high, and the position of the ball hole outer ring 10 in the seat hole is. Therefore, the novel knuckle bearing is convenient to install and stable in connection, reduces the machining difficulty and improves the production efficiency.
