Problems solved by technology

[0003] Existing reducers for photovoltaics generally use single slewing bearings or double slewing bearings to realize the installation of worm gears. This type of design is costly, difficult to install, bulky, and prone to jamming or worm screwing when installing the worm. The surface is prone to wear and tear, which is not conducive to long-term use. At the same time, the service life of the photovoltaic reducer needs to reach 20 years. If it is in a harsh environment for a long time, it is prone to wear and tear, and the transmission efficiency will be greatly reduced and accompanied by transmission noise. The later maintenance work is relatively large.

Embodiment 1

[0046] Figure 1 to Figure 11 Divide Figure 7 to Figure 9 As shown, the photovoltaic power generation double-shaft output rotary drive device includes a housing 1, a worm gear 2, a worm 3, and a drive motor 4. The housing 1 is provided with an upper cavity and a lower cavity communicating with each other;

[0047] The worm wheel 2 is symmetrically provided with a stepped shaft, and both ends of the stepped shaft on the worm wheel 2 are fixedly connected with a fixing frame 5 connected with the photovoltaic support;

[0048] The upper cavity is provided with a sealed revolving mechanism. The sealed revolving mechanism includes a sliding bearing 7, a mounting port 8, a mounting port 9, and a sealing assembly. The sliding bearing 7 is provided with two stepped shafts respectively installed on both sides of the worm wheel 2. One of the sliding bearings 7 is sealed and installed at the installation port 8 through an oil seal frame, and the other sliding bearing 7 forms a sealed fit bet...

Embodiment 2

[0056] by Figure 7 to Figure 9 As shown, since the first blocking member and the second blocking member are still in a sealed state under the action of the adjusting member, a relatively large force is required to press the two to make them move. One adjustment structure on the side shell 1 of the first 13 part, and the other adjustment structure on the side shell 1 of the blocking part two 14. Both adjustment structures include a two-way screw 17, a ratchet 18, a locking block 19, and two two-way screws 17 are respectively rotatably connected to the housing 1 at the bottom of the corresponding plugging piece 13 or plugging piece two 14, and the end of the two-way screw 17 is provided with an inner hexagon hole. The adjustment of the two-way screw 17 is realized by an inner hexagon wrench. Two wedge-shaped sliders 20 in opposite directions are connected to the screw 17 through threads. The ratchet rack 18 is fixedly connected to the corresponding blocking piece 13 or the corre...

Embodiment 3

[0058] Example 3: Installation method of the device

[0059] The installation method of the double-shaft output rotary drive device for photovoltaic power generation includes the following steps:

[0060] S1, Worm gear 2 installation: First, put the two sliding bearings 7 on both sides of the worm wheel 2, and use bolts to connect the worm wheel 2 to the fixing frame 5 of the photovoltaic bracket, and connect the worm wheel 2 and the sliding bearing 7 as a whole by a sealing accessory One side of 11 is inserted into the upper cavity;

[0061] S2, Worm 3 installation: first fix the two bearings on the worm 3 with the inner ring, then screw the end that is not connected to the drive motor 4 into the lower cavity until the distance between the two bearings and the lower cavity port is equal, Fixing the first 13 blocking member and the second blocking member 14 to the corresponding outer ring of the bearing respectively, and the adjusting member 15 penetrates the corresponding adjusting...

Abstract

The invention discloses a photovoltaic-power-generation double-shaft output rotary driving device, a mounting method and a clearance adjusting method, and belongs to the technical field of photovoltaic speed reducers. A worm gear and an upper cavity of a housing are hermetically mounted through a sealing rotary mechanism, and a worm and a lower cavity are hermetically mounted through a clearance adjusting mechanism, so that a center distance between the worm gear and the worm can be adjusted conveniently during mounting of the worm gear and the worm, after long-term use and abrasion of the worm gear and the worm, compensation is achieved through the clearance adjusting mechanism, so that the transmission efficiency of the device is guaranteed, noise is reduced, and meanwhile, a driving motor and the worm can synchronously move through an adjusting base, so that the transmission efficiency of the device is improved, and the service life is prolonged.

Description

Technical field [0001] The invention belongs to the technical field of photovoltaic reducers, and specifically relates to a photovoltaic power generation double-shaft output rotary drive device with a simple structure and a gap adjustment function, an installation method and a gap adjustment method. Background technique [0002] Photovoltaic power generation is an important application field of the rotary reducer. The rotary reducer is the core component of the tracking system for photovoltaic power generation. It is driven by a motor and runs at a certain speed. The rotary reducer drives the driven component to rotate in the horizontal direction or the elevation direction, so that it always faces the sun. The rotation and elevation angle of the host can be precisely adjusted according to the different positions of the sun during the day. A good receiving angle can significantly improve the efficiency of solar power generation. The "sun-tracking" photovoltaic power generation sy...
