DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Please refer to Figures 1-4This utility model provides an embodiment of a self-lubricating worm gear for tracking and steering photovoltaic panels, comprising a self-lubricating shell 1, a worm gear cavity 101 inside the self-lubricating shell 1, a worm gear 3 rotatably connected inside the worm gear cavity 101, a worm shaft cavity 102 on one side of the worm gear cavity 101, a worm shaft 4 rotatably connected inside the worm shaft cavity 102, and triangular isolation blocks 103 fixedly connected at both ends of the self-lubricating shell 1 between the worm gear cavity 101 and the worm shaft cavity 102. Lubricating oil circulation channels 104 are provided on the outer sides of both triangular isolation blocks 103. The worm shaft 4 extends to one side of each of the two triangular isolation blocks 103 and is fixedly connected to a spiral lubricating oil conveying blade 401. One side of the worm gear 3 passes through the two triangular isolation blocks 103. Between 03 and meshing with the middle teeth on one side of the worm 4, the two lubricating oil circulation channels 104 are connected on one side to the front and rear ends of the worm gear cavity 101, and on the other side to the front and rear ends of the worm cavity 102. During use, a large amount of lubricating oil is injected into the worm gear cavity 101 and the worm cavity 102. When the worm gear 3 and worm 4 mesh and transmit power, the rotation of the worm 4 synchronously drives the two spiral lubricating oil conveying blades 401 to rotate. This causes the two spiral lubricating oil conveying blades 401 to carry the lubricating oil inside the self-lubricating housing 1 along the path "worm cavity 102 -- rear end lubricating oil circulation channel 104 -- worm gear cavity 101 -- front end lubricating oil circulation channel 104 -- worm cavity 102" (see...). Figure 4 The circulation path ensures that the lubricating oil flows smoothly, preventing it from remaining stagnant in the cavity inside the self-lubricating housing 1, which could lead to lubrication failure between the worm gear 3 and the worm 4.

[0024] Please see Figure 2 and Figure 3 A top cover 105 is connected to the upper end of the self-lubricating housing 1. The top cover 105 is fixedly connected to the upper end of the self-lubricating housing 1 by multiple first screws 107. Limiting tubes 2 are fixedly connected to the middle of the upper end face of the top cover 105 and the middle of the lower end face of the self-lubricating housing 1. A drive shaft 301 is fixedly connected to the middle of the worm gear 3. The lower end of the drive shaft 301 is inserted into the limiting tube 2 on the lower end face of the self-lubricating housing 1, and the upper end of the drive shaft 301 passes through the limiting tube 2 on the upper end face of the top cover 105 and extends out of the upper end face of the top cover 105. The upper and lower ends of the drive shaft 301 are rotatably connected to the two limiting tubes 2 by bearings 202. On the adjacent side of 202, a first sealing ring 201 is provided between the upper and lower ends of the transmission shaft 301 and the two limiting tubes 2 inside. A fixing tube 5 is fixedly connected to the front end of the self-lubricating shell 1. The rear end of the worm 4 is inserted into the self-lubricating shell 1 and rotated. The front end of the worm 4 extends out of the front end face of the self-lubricating shell 1 through the fixing tube 5 and is connected to the drive device. The upper end of the transmission shaft 301 extends out of the upper end face of the upper cover 105 and is fixedly connected to the bottom rotating seat of the photovoltaic panel. The drive device drives the worm 4 to rotate, so that the worm 4 drives the worm wheel 3 and the transmission shaft 301 to rotate, thereby driving the bottom of the photovoltaic panel to rotate.

[0025] Please see Figure 2 and Figure 3 A rectangular opening 106 is provided in the middle of the end face of the self-lubricating housing 1 adjacent to the worm gear cavity 102. A cover 6 is connected to the outside of the rectangular opening 106. A third sealing ring 601 is provided between the cover 6 and the outside of the rectangular opening 106 of the self-lubricating housing 1. The cover 6 and the self-lubricating housing 1 are fixedly connected by multiple second screws 602. By opening the cover 6, it is convenient to add lubricating oil into the self-lubricating housing 1 through the rectangular opening 106.

[0026] Working principle: During use, sufficient lubricating oil is injected into the worm gear cavity 101 and worm shaft cavity 102 inside the self-lubricating housing 1 through the rectangular opening 106 by opening the cover 6. When the drive device (such as a servo motor) drives the worm 4 to rotate, the worm 4 meshes with the worm wheel 3, driving the worm wheel 3 and the drive shaft 301 to rotate, thereby adjusting the orientation of the photovoltaic panel to achieve solar tracking. During this process, the spiral lubricating oil delivery blades 401 fixed at both ends of the worm 4 rotate synchronously with the worm 4, pushing the lubricating oil to form a circulation flow in the housing: the lubricating oil enters the worm gear cavity 101 from the worm shaft cavity 102 through the rear lubricating oil circulation channel 104, and then flows back to the worm shaft cavity 102 through the front lubricating oil circulation channel 104 (such as a servo motor). Figure 4 (As shown). This circulation path prevents lubricating oil from accumulating and failing due to stagnation, ensuring continuous lubrication of the tooth surfaces of the worm gear 3 and worm 4. At the same time, the circulating lubricating oil can also carry away the heat generated by friction, further extending the service life of the transmission components. The design of the sealing rings (first sealing ring 201, third sealing ring 601) and bearing 202 effectively prevents lubricating oil leakage and ensures long-term stable operation of the system.
