Description

Technical Field

[0001] The utility model relates to the technical field of bearings, and in particular to a graphite sleeve, a bearing and a photovoltaic tracker which are easy to maintain. Background Art

[0002] Photovoltaic tracker is a photovoltaic support system that can automatically track the sun and increase overall power generation. It is widely used in the field of photovoltaic power generation.

[0003] Bearings are an important component of photovoltaic trackers. The bearing sleeves of related photovoltaic trackers are generally made of plastic, and the bearing seats of bearings are generally made of metal. The friction between plastic and metal can easily lead to greater friction in the bearings. At the same time, the bearing sleeves of related photovoltaic trackers are generally two semi-cylinders. When one of the semi-cylinders is damaged, the bearing can easily become unusable, which in turn causes the main shaft to fail to operate normally, and the fault tolerance rate is low. Utility Model Content

[0013] Optionally, it further includes a plurality of receiving holes each provided in at least one of the sleeve bodies, and the plurality of graphite columns are correspondingly located in the plurality of receiving holes.

[0014] Optionally, the number of the sleeve bodies is four, two of which are configured as first sleeve assemblies, and the other two are configured as second sleeve assemblies, and a radial gap is provided between the first sleeve assemblies and the second sleeve assemblies.

[0015] Optionally, the at least two sleeve bodies are both connected to a limiting ring.

[0016] A bearing comprises a graphite sleeve which is easy to maintain and a bearing seat. The at least two sleeve bodies are rotatably sleeved in the bearing seat, and the graphite component is in contact with the inner wall of the bearing seat.

[0017] A photovoltaic tracker includes a bearing and further includes:

[0018] A main shaft, wherein the non-rotating holes of the at least two sleeve bodies are matched with the main shaft;

[0019] A hoop is sleeved on the outside of the main shaft, and the hoop is in contact with one end of the at least two sleeve bodies close to the limiting ring.

[0020] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0021] 1) The graphite assembly is used to increase the lubricity between the sleeve body and the bearing seat, thereby reducing the friction between the sleeve body and the bearing seat, thereby reducing the friction of the related bearings, thereby increasing the service life of the easy-to-maintain graphite sleeve, reducing the replacement frequency, and facilitating maintenance;
