Description

Technical Field

[0001] The utility model relates to the technical field of slewing bearings, in particular to a solar photovoltaic slewing bearing. Background Art

[0002] Photovoltaic power generation is based on the principle of the photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. Whether it is used independently or connected to the grid, the photovoltaic power generation system is mainly composed of three parts: solar panels, controllers and inverters. They are mainly composed of electronic components but do not involve mechanical parts. In order to increase the time that photovoltaic panels receive sunlight, the steering function of the slewing bearing is used to allow the photovoltaic panels to receive sunlight for a longer time, thereby generating more electricity.

[0003] The slewing bearing is a new type of mechanical component, which consists of inner and outer rings, rolling elements, etc. The slewing bearing is a large bearing that can withstand comprehensive loads and can simultaneously withstand large axial and radial loads and overturning moments. When the slewing bearing is used for a long time, it is necessary to inject lubricant into the inside from the side gap to reduce the internal friction, thereby increasing the service life of the slewing bearing. However, the lubricant flows away with the action of gravity after injection and cannot continue to exist inside the slewing bearing. This not only wastes the lubricant, but also has a poor lubrication effect. In order to improve the lubrication effect of the lubricant, this scheme proposes a solar photovoltaic slewing bearing. Utility Model Content

[0004] The utility model aims to solve the shortcoming of poor lubrication effect after lubricant injection in the prior art, and proposes a solar photovoltaic slewing bearing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The solar photovoltaic slewing bearing comprises an outer steel ring, the outer side of which is provided with tooth blocks, the intervals between the tooth blocks are of the same size, a circular groove is opened on the top of the outer steel ring, the top of the outer steel ring is located inside the circular groove and is rotatably connected with rotating beads, the number of rotating beads is eight, the top of the outer steel ring is located inside the circular groove and is provided with penetration grooves, the intervals between the penetration grooves are of the same size, the inner side of the outer steel ring is rotatably connected with rolling balls, and the rolling balls are rotatably connected with the inner steel ring.

[0007] Preferably, the depth of the circular groove is the same as the diameter of the rotating ball.

[0008] Preferably, the depth of the permeable groove is half of the depth of the circular groove, and the depth of the permeable groove is half of the diameter of the rotating bead.

[0009] Preferably, a circular groove is provided in the middle of the top of the inner steel ring, and a circular groove is provided in the middle of the top of the inner steel ring on the outside of the circular groove.

[0010] Preferably, a connecting hole is provided in the middle of the top of the inner steel ring at the bottom of the circular groove, and a locking groove is provided at the bottom of the inner steel ring at one side of the connecting hole.

[0011] Preferably, the top of the inner steel ring is symmetrically provided with limiting holes located in two circular grooves, and the intervals between the limiting holes are the same.

[0012] The utility model has the following beneficial effects:

[0013] The slewing bearing is installed on the connection of the solar photovoltaic panel, and then fixed with bolts. At this time, the solar photovoltaic panel can rotate under the action of the rolling ball of the outer steel ring and the inner steel ring. With the influence of time, it is necessary to inject lubricant between the outer steel ring and the inner steel ring. At this time, the lubricant is slowly injected into the circular groove on the top of the outer steel ring through the gap at the connection. At this time, the lubricant that exceeds the height of the penetration groove will directly fall between the outer steel ring and the inner steel ring, thereby achieving the effect of direct lubrication. When the solar photovoltaic panel rotates again, under the action of the rotating ball, the remaining lubricant in the circular groove will fluctuate, so that the liquid level exceeds the penetration groove, so that the lubricant can still be slowly injected between the outer steel ring and the inner steel ring, thereby achieving the effect of continuous lubrication.
