Description

Technical Field

[0001] This utility model discloses a speed reducer device, belonging to the field of photovoltaic rotary speed reducer technology, specifically relating to a photovoltaic rotary speed reducer with overload protection. Background Technology

[0002] In photovoltaic (PV) tracking systems, the rotary reducer plays a crucial role. As a speed reduction device, it effectively controls the operating speed of the PV tracker through the precise coordination of the drive wheel, intermediate gear, and output wheel. This application not only achieves optimal solar panel coverage but also significantly improves PV power generation efficiency through automatic tracking. Furthermore, by optimizing the PV panel's motion trajectory and reducing the motion frequency, the rotary reducer minimizes equipment wear and effectively extends the equipment's lifespan.

[0003] The rotary reducer offers significant advantages in photovoltaic tracking systems, primarily in three aspects: high efficiency and energy saving, high stability, and long service life. It can reduce the angle between the photovoltaic panel and sunlight, improving power generation efficiency while simultaneously reducing equipment energy consumption.

[0004] Traditional rotary reducers are prone to overload during operation. Under overload conditions, the stress on the gears increases significantly, intensifying friction between the tooth surfaces and accelerating tooth wear. This can lead to tooth spalling, scuffing, and in severe cases, gear breakage. Bearings can also be damaged by overload, such as ball bearing breakage and cage deformation. Furthermore, shaft deformation and damage are common consequences of overload operation, potentially causing fatigue damage or even shaft breakage. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] A photovoltaic rotary reducer with overload protection includes: a worm gear 1, a worm 2, a drive shaft 3, and an overload protection component 4.

[0020] In one embodiment, such as Figure 1 As shown, the worm gear 1 meshes with the worm 2, the transmission shaft 3 is sleeved on the worm gear 1, both ends of the transmission shaft 3 are rotatably mounted in the reducer body, and the overload protection component 4 is mounted on the transmission shaft 3;

[0021] In one embodiment, such as Figure 1 As shown, the overload protection component 4 includes: a fixed base 40, a movable spring seat 41, a fixed spring seat 42, a spring 43, and a pressure-reducing ring 44; the fixed base 40, the movable spring seat 41, and the fixed spring seat 42 are sleeved on the transmission shaft 3, the spring 43 is located between the movable spring seat 41 and the fixed spring seat 42, the fixed base 40 cooperates with the fixed spring seat 42, and the pressure-reducing ring 44 is located between the fixed base 40 and the fixed spring seat 42.

[0022] In one embodiment, such as Figure 1 As shown, the transmission shaft 3 adopts a stepped structure, and the transmission shaft 3 is connected to the worm gear 1 by a key. The transmission shaft 3 is provided with a key block 5.

[0023] In one embodiment, such as Figure 1As shown, one end of the drive shaft 3 is rotatably mounted on one end of the reducer body via a ball bearing. The reducer body has a cover 6 on its outer side and a sealing cover 7 on its inner side. The sealing cover 7 is fixedly connected to the cover 6 by bolts. The sealing cover 7 is sleeved on the drive shaft 3 and a sealing ring 8 is provided between them.

[0024] In one embodiment, such as Figure 1 As shown, the other end of the drive shaft 3 is rotatably mounted on the other end of the reducer body via a ball bearing, and the drive shaft 3 extends to the outside.

[0026] Working principle: When this utility model is working, the worm 2 first rotates and meshes with the worm wheel 1, thereby driving the worm wheel 1 to rotate, which in turn drives the transmission shaft 3 to rotate. The transmission shaft 3 rotates through the ball bearing. At the same time, when overload occurs, the movable spring seat 41 in the overload protection component 4 compresses the spring 43 and moves it towards the fixed spring seat 42, thereby reducing the speed of the transmission shaft 3 and thus providing protection.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
