[0050] In order to make the above objectives, characteristics and advantages of the present application more apparent, the following will describe the specific embodiments of the present application in detail in conjunction with the accompanying drawings.
[0051] Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
[0052] Further, although the terms used in the present application are selected from publicly-known terms, some of the terms mentioned in the specification of the present application can be selected by the applicant in his or her judgment, and the detailed meanings thereof are described in the relevant part of the description herein.
[0053] Further, the present application is to be understood not only by the actual terms used but also by the meanings of each term implied therein.
[0054] As Figures 1 to 6 shown in the drawings, the present application discloses a damping bearing with angle self-adaptive function, comprising a bearing outer ring 10, a bearing inner ring 20, a bearing seat 30, a left end cover 40 and a right end cover 50, the bearing outer ring 10 is installed in the bearing seat 30, the bearing inner ring 20 is installed in the bearing outer ring 10, the left end cover 40 and the right end cover 50 respectively fix the bearing outer ring 10 in the bearing seat 30 from both sides.
[0055] A first sealing ring 60 is further installed between the outer edge of the left end cover 40 and the bearing outer ring 10, a second sealing ring 61 is further installed between the right end cover 50 and the bearing outer ring 10, a first spacer sleeve 70 is further installed between the bearing outer ring 10 and the bearing seat 30, and a second spacer sleeve 71 is further installed between the inner side of the right end cover 40 and the bearing outer ring 10.
[0056] A groove 11 with an annular surface is arranged on the bearing outer ring 10, and an annular key groove 12 is arranged on the groove 11. An annular spline 21 is arranged on the outer surface of the bearing inner ring 20. The bearing inner ring 20 is rotatably matched with the bearing outer ring 10 through the cooperation of the annular spline 21 and the annular key groove 12, so that the bearing inner ring 20 can move relative to the bearing outer ring 10 in any radial plane of the damping bearing.
[0057] As shown in the embodiment, the bearing inner ring 20 can be spliced by multiple circular arc structures, for example, two semicircular arc structures or three or four circular arc structures. These are all within the protection scope of the present application and will not be described here. Figure 5
[0058] The damping bearing realizes the transmission of damping force of the damping bearing and driving force of the transmission system through the cooperation of the annular inner and outer splines. In addition to transmitting load, the cooperation of the annular splines of the bearing inner ring 20 and the bearing outer ring 10 can also realize the relative movement of the bearing inner ring 20 relative to the bearing outer ring 10 in any radial plane of the damping bearing, so that the damping bearing has a certain angle adjustment amount.
[0059] Preferably, the annular spline 21 of the bearing inner ring 20 is a variable-thickness annular spline. The annular key groove 12 of the bearing outer ring 10 is a variable-thickness annular key groove.
[0060] Since the outer annular spline of the bearing inner ring 20 is a variable-thickness annular spline, and the inner annular spline groove of the bearing outer ring 10 is a variable-thickness annular spline groove, when the two relative movements are realized, the outer annular spline and the inner annular spline groove are mutually locked after the bearing inner ring 20 is deflected to a certain angle, thereby preventing the bearing inner ring 20 from continuing to deflect and realizing the mechanical limiting protection function of the support system.
[0061] In addition to the above-mentioned mechanical limiting protection function, a ring surface groove is machined at a position with a large width of the inner spline groove of the bearing outer ring 10, and a spring retainer 80 is installed therein. The spring retainer 80 functions as a second mechanical limiting protection and prevents the bearing inner ring from being excessively deflected.
[0062] Further, in order to be able to fasten the pipe, at least one pair of wedge blocks 90 is symmetrically arranged on the bearing inner ring 20 in the circumferential direction, and the wedge blocks 90 are adjusted to slide relative to the bearing inner ring 20.
[0063] The wedge block 90 is connected with the bearing inner ring 20 through a connecting piece 92, and the inner surface of the bearing inner ring 20 is arranged as an inclined surface. The inclined surface 91 of the wedge block 90 cooperates with the inner surface of the bearing inner ring 20 (as shown in Figure 6 The connecting member is preferably a bolt. The damping bearing can achieve the relative sliding between the wedge block 90 and the inner ring 20 of the bearing by adjusting the screwing degree of the connecting member (e.g. the bolt).
[0064] When the connecting member (e.g. the bolt) is screwed, the wedge block 90 slides inward, gradually eliminating the gap between the wedge block 90 and the square tube, and achieving the clamping function. When the connecting member (e.g. the bolt) is loosened, the wedge block 90 slides outward, and the gap between the wedge block 90 and the square tube gradually increases, achieving the disassembly of the square tube.
[0065] Further, by uniformly arranging the wedge blocks 90 on the inner ring 20 at intervals of 90°, the wedge blocks 90 can not only achieve the clamping function, but also adjust the misalignment during the installation of the square tube. If the center of the square tube installation and the center of the damping bearing are not in the same center, there is a misalignment, which can be adjusted by adjusting the adjusting bolts of the wedge blocks 90 at the upper and lower or left and right ends of the square tube, to ensure the normal operation of the tracking support system.
[0066] The utility model also provides a photovoltaic tracking support which comprises the damping bearing with the angle self-adaptive function as described above.
[0067] In summary, the damping bearing with the angle self-adaptive function has the following effects:
[0068] I. The damping function and the bearing function of the damping bearing are separated, the square tube can realize the adjustment of the installation angle and adapt to the inclination angle of the square tube caused by the installation of the slope or the parts of the support system while retaining the damping function of the original damping bearing.
[0069] II. In the bearing assembly, the wedge blocks arranged circumferentially can adjust the clamping when there is a misalignment between the center of the square tube and the center of the damping bearing.
[0070] III. The wedge blocks can not only realize the misalignment self-adaption, but also realize the clamping of the square tube, eliminating the gap between the square tube and the bearing assembly, so as to ensure the smooth transmission of the force in the transmission system.
