Description

Technical Field

[0001] The invention belongs to the field of solar tracking reducers and relates to a high-efficiency parallel-axis heightened input reducer. Background Art

[0002] The center distance between the input shaft and the output shaft of the existing parallel shaft slewing reducer is relatively small. When solving the problem of photovoltaic panels on the bracket tracking the sun, it is necessary to consider that the photovoltaic panels may collide with the input shaft during tracking. Therefore, there are very high requirements for the hard limit of the slewing reducer, which in turn leads to the limitation of the tracking angle of the entire photovoltaic panel. As the angle decreases, the power generation efficiency decreases. At the same time, due to the small center distance between the input shaft and the output shaft, in the case of limited space, there may be no place to place the motor that meets the working conditions, which increases the difficulty of motor selection. In addition, the existing parallel shaft slewing reducers are suitable for a single product specification and cannot meet the needs of product diversification. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides a high-efficiency parallel-axis heightened input reducer.

[0004] A high-efficiency parallel shaft heightened input reducer is divided into an upper base and a lower base, and the upper base and the lower base are fixedly connected by a connecting rod; the upper base includes a worm gear chamber, a first worm gear chamber and an output shaft, the worm gear chamber is integrally connected above the first worm gear chamber, a worm gear is arranged in the worm gear chamber, a first worm is arranged in the first worm gear chamber, the first worm gear and the worm gear are meshed, and the output shaft passes through the worm gear chamber and the worm gear in sequence; the lower base includes a gear chamber, a second worm gear chamber and a connecting rod shaft, the gear chamber is integrally connected below the second worm gear chamber, a first bevel gear is arranged in the gear chamber, the connecting rod shaft passes through the gear chamber and the first bevel gear in sequence, a second worm gear is arranged in the second worm gear chamber, second bevel gears are sleeved at both ends of the second worm gear, a third bevel gear is sleeved at the inner end of the first worm gear, and the second bevel gear is respectively meshed with the first bevel gear and the third bevel gear.

[0005] According to a preferred embodiment of the present invention, the angle between the lower substrate and the upper substrate is an acute angle.

[0006] According to a preferred solution of the present invention, the first worm cavity and the gear cavity are fixedly connected via a connecting rod.

[0007] According to a preferred embodiment of the present invention, the outer end of the first worm is the first input end, and one end of the connecting rod shaft is the second input end.

[0008] The beneficial effects of the present invention are:

[0009] 1. The reducer is provided with two input ends. If the first input end is connected to the motor, the first worm as the input shaft is in a vertical state with the output shaft. If the second input end is connected to the motor, the connecting rod shaft as the input shaft is in a horizontal state with the output shaft.

[0010] 2. When the connecting rod shaft and the output shaft are horizontal, the upper base and the lower base are separately arranged, the center distance between the connecting rod shaft and the output shaft is larger, the problem of limited deflection of the photovoltaic panel can be solved, and the motor is installed under the photovoltaic panel bracket, which improves the utilization rate of the floor space and thus increases the power generation.

[0011] 3. When the first worm and the output shaft are in a vertical state, the rotation of the components of the shorter photovoltaic panels can be satisfied, thereby increasing the selectivity of the motor on the one hand and adapting to the diversity of the product on the other.

DETAILED DESCRIPTION

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0018] In the description of the invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the invention.

[0019] In the description of the invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two components, and a fixed connection can be welding, gluing, etc. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1 and Figure 2 A high-efficiency parallel-axis heightened input reducer is shown, which is divided into an upper base 9 and a lower base 13, and the upper base 9 and the lower base 13 are fixedly connected; by setting the upper base 9 and the lower base 13 separated, the distance between the photovoltaic panel and the motor can be increased, thereby solving the problem of limited deflection of the photovoltaic panel and improving the power generation efficiency.

[0021] The upper base 9 includes a worm gear cavity 2, a first worm cavity 7 and an output shaft 1. The worm gear cavity 2 is integrally connected above the first worm cavity 7. A worm wheel 16 is provided in the worm gear cavity 2. A first worm 15 is provided in the first worm cavity 7. The first worm 15 is meshed with the worm gear 16. The output shaft 1 passes through the worm gear cavity 2 and the worm wheel 16 in sequence. The outer end of the first worm 15 is the first input end 3. If the first input end 3 is connected to the motor, the first worm 15 serves as the input shaft. At this time, the first worm 15 drives the output shaft 1 to rotate through the worm wheel 16. The first worm 15 and the output shaft 1 are in a vertical state, so that the shorter components of the photovoltaic panel can be rotated.

[0022] The lower base 13 includes a gear cavity 4, a second worm cavity 6 and a connecting rod shaft 5. The gear cavity 4 is integrally connected to the lower part of the second worm cavity 6. A first bevel gear 14 is arranged in the gear cavity 4. The connecting rod shaft 5 passes through the gear cavity 4 and the first bevel gear 14 in sequence. A second worm 12 is arranged in the second worm cavity 6. Second bevel gears 11 are sleeved at both ends of the second worm 12. A third bevel gear 10 is sleeved at the inner end of the first worm 15. The second bevel gear 11 is meshed with the first bevel gear 14 and the third bevel gear 10 respectively. One end of the connecting rod shaft 5 is the second input end. If the second input end is connected to the motor, the connecting rod Shaft 5 serves as the input shaft. The rotation of the connecting rod shaft 5 drives the first bevel gear to rotate, and then drives the second worm 12 and the first worm 15 to rotate through the second bevel gear. The first worm 15 drives the worm wheel 16 to rotate, and then the output shaft 1 rotates. At this time, the connecting rod shaft 5 and the output shaft 1 are in a parallel state. Since the upper base 9 and the lower base 13 are separately arranged, the center distance between the output shaft 1 and the connecting rod shaft 5 is large at this time, which can adapt to the rotation of longer photovoltaic panel assemblies without angle limitation, thereby increasing power generation. At the same time, the motor is installed under the photovoltaic panel bracket, which improves the utilization rate of the floor space.

[0023] like Figure 3 As shown, the use of a heightened parallel shaft input reducer has more advantages in tracking angles. Taking a tracking angle of 60 degrees as an example, the connecting rod shaft 5 of the heightened parallel shaft input reducer will not interfere with the purlins on the photovoltaic panel bracket, while this interference will occur with a conventional ordinary reducer, requiring the bracket structure to be changed.

[0024] At the same time, the first worm 15 is used as the input shaft and the connecting rod shaft 5 is used as the input shaft to be respectively vertical and horizontal to the output shaft 1, so as to optimally adapt to the rotation of photovoltaic panel assemblies of different lengths, thereby adapting to product diversification and increasing the selectivity of the motor.

[0025] The angle between the lower base 13 and the upper base 9 is an acute angle; the upper base 9 and the lower base 13 are separately arranged and arranged at an acute angle, thereby improving space utilization.

[0026] The first worm cavity 7 and the gear cavity 4 are fixedly connected via a connecting rod 8 to increase support.

[0027] The above is based on the present invention as an inspiration. Through the above description, relevant staff can make various changes and modifications without departing from the technical idea of ​​this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
