[0035] Reference will be made below Figures 1-5 The limiting bearing 20 according to the embodiments of the utility model is described.
[0036] According to the limiting bearing 20 of the first aspect of the utility model embodiment, the limiting bearing 20 is used for a photovoltaic system, the limiting bearing 20 includes a support seat 2 and a bearing 3, the support seat 2 is formed with a mounting cavity 21, the bearing 3 is rotatably installed in the mounting cavity 21, the mounting cavity 21 penetrates the support seat 2 along the front-back direction, the bearing 3 has a hollow cavity 36 penetrating the bearing 3 along the front-back direction of the bearing 3, the photovoltaic system further includes a main beam, the main beam is fixed in the hollow cavity 36, when the bearing 3 rotates relative to the support seat 2, the main beam can be driven to rotate synchronously, and the main beam is connected with a cell panel, so that the cell panel is driven to rotate synchronously.
[0037] The inner wall of the mounting cavity 21 is provided with a first limiting part, a second limiting part, a third limiting part and a fourth limiting part, the bearing 3 includes a first part 31 and a second part 32 connected, the first part 31 abuts against the inner wall, and the second part 32 is spaced apart from the inner wall, and the first part 31 of the bearing 3 is used to support the bearing 3 in the mounting cavity 21.

[0046] When the bearing 3 rotates, the limiting plate 33 can push the first rolling member to roll, and in the first limiting position, the first rolling member abuts against the first limiting part, the limiting plate 33 is located on the side of the first rolling member away from the first limiting part, and at the same time, the first part 31 abuts against the fourth limiting part, for limiting the bearing 3 in the first limiting position, and by virtue of the self-gravity of the first rolling member, the first limiting part and the bearing 3 can be further compressed, the bearing 3 can exert a force on the fourth limiting part, for limiting the bearing 3 in the first limiting position, and the reliability of the bidirectional limiting of the bearing 3 can be further realized.

[0055] Since the second inclined surface 231 is arranged downwardly inclinedly, when the second roller 42 is in contact with the second inclined surface 231, the second roller 42 can be pressed tightly on the bearing 3, and the bearing 3 will apply pressure to the second limiting portion, so as to achieve the effect of bidirectional limiting of the bearing 3.
