Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and techniques are omitted so as to not unnecessarily limit the invention.

Example 1

As shown in fig. 1 to 3, an electric push rod transmission structure suitable for a photovoltaic tracking support comprises a screw rod 1, a shaft sleeve gear 2, a gear box body 3, a driving gear 4 and a driving motor 5.

The screw rod 1 penetrates through the shaft sleeve gear 2 and is matched with the threads on the inner wall of the shaft sleeve gear 2. The sleeve gear 2 is rotatably hinged in the gear case 3, and the sleeve gear 2 is positioned and rotatable by the gear case body 3. The driving gear 4 is also rotatably arranged in the gear box body 3 and is in meshing transmission with the shaft sleeve gear 2 through a certain speed ratio; the drive gear 4 may be a single gear or a gear set; the driving gear 4 and the sleeve gear 2 may be made of nylon, polymer material, metal, or the like. The driving motor 5 is arranged on the gear box 3, and the driving gear 4 is connected with a power output shaft of the driving motor 5; the connection mode can be key connection, expansion ring connection, set screw connection, interference fit connection and the like.

Example 2

As shown in fig. 4 to 6, the electric push rod transmission structure suitable for the photovoltaic tracking support further includes an oil cylinder 6, a bearing 7, a protective outer shell 8, a protective inner shell 9, and a sealing member 10.

In order to prevent the output force from being too large and causing the gear housing 3 to be broken, the bearing 7 is installed at the hinged portion of the sleeve gear 2 and the gear housing 3, and the bearing 7 is rotatably hinged with the sleeve gear 2. The protective inner shell 9 is sleeved on the outer side of the upper part of the screw rod 1, the lower end of the protective inner shell is fixedly arranged on the gear box body 3, and the fixing mode can be welding, threaded connection, hinging, bonding and other connecting modes.
