Description
Technical Field
The utility model belongs to the field of rotary speed reducers of solar tracking systems, and particularly relates to a self-lubricating gear middle shaft.
Background
The structure that current rotation reducer gear shaft applied to solar tracking system generally adopted is the structure of output spindle nose center and output shaft center coaxial axle, this structure is often because the focus of photovoltaic module is not coaxial with rotation reducer's rotation center after the on-the-spot installation photovoltaic module, photovoltaic module's dead weight can produce certain eccentric moment, and the relative gyration of support between current gear axis and the base casing in the market mainly realizes through antifriction bearing or slide bearing's structure, these two kinds of structures can appear with increased costs, phenomenon such as structure is not compact.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model aims to provide a self-lubricating gear middle shaft to solve the problems in the background technology.
In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a self-lubricating gear axis, includes output shaft, output spindle nose, be provided with bellied step on the output shaft, be provided with one section gear portion on the bellied step, be provided with the output spindle nose of symmetry on the terminal surface of output shaft, the output shaft center is the non-collinear structure with output spindle nose center, be provided with the oil groove on the output shaft of gear portion both sides.
In a preferred embodiment of the present invention, the oil grooves are symmetrically distributed on the output shafts on both sides of the gear portion, and end surfaces of the oil grooves are slightly higher than end surfaces of the output shafts, so as to prevent grease from overflowing.
As a preferable scheme of the utility model, grease is arranged in the oil groove, and the grease can play a lubricating role.
As a preferable scheme of the utility model, at least two oil grooves are arranged on each side, and the oil groove structure can lead the structure to be compact and save the production cost.
As a preferable scheme of the utility model, the section of the output shaft head is square, the mounting surface of the output shaft head is provided with a mounting hole, the problem of bolt looseness is solved due to the square structure of the section of the output shaft head, and the square structure is convenient to form.
As a preferable scheme of the utility model, one of the symmetrical center lines of the output shaft heads is collinear with one of the center lines of the output shafts, so that after the photovoltaic module is installed, the center of gravity of the photovoltaic module is collinear with the rotation center of the output shaft, and the eccentric moment generated by the self weight of the photovoltaic module is reduced.
The utility model has the beneficial effects that: adopt output shaft center and output spindle nose center to be non-collinear structure, can make photovoltaic module reduce the eccentric moment who produces by photovoltaic module dead weight after having installed on the output shaft, and be provided with the oil groove of certain quantity on the output shaft, be provided with a certain amount of lubricating grease in the oil groove, can produce the lubrication action, also saved the cost of production when improving compact structure.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below by combining the attached drawings in the embodiment.
The self-lubricating gear middle shaft is different from a structure that the center of an output shaft head and the center of an output shaft are coaxial, which is adopted by a gear shaft of a rotary speed reducer of a traditional solar tracking system, so that after a photovoltaic module is installed on site, the center of gravity of the photovoltaic module is not coaxial with the center of rotation of the rotary speed reducer, and the dead weight of the photovoltaic module can generate a certain eccentric moment. Referring to fig. 1 and 3, a raised step is arranged on the output shaft, a section of gear part 3 is arranged on the raised step, the length of the gear part can be set according to the actual situation in use, the center of the output shaft and the center of the output shaft head are of a non-collinear structure, the condition that the gravity center of the photovoltaic module is not coaxial with the rotation center of the rotary speed reducer and the dead weight of the photovoltaic module generates a certain eccentric moment is avoided.
Referring to fig. 2, oil grooves 4 are formed in the axial surface of the output shaft, the oil grooves 4 are symmetrically distributed on two sides of the gear portion, grease is arranged in the oil grooves, a lubricating effect is achieved, at least two oil grooves are formed in one side of the gear portion, the end face of the top of each oil groove is slightly higher than the end face of the output shaft, the grease is prevented from overflowing, and a series of problems caused by grease leakage are avoided.
Referring to fig. 3, symmetrical output shaft heads 2 are arranged on the end face of the output shaft 1, the cross section of each output shaft head is square, mounting holes are formed in mounting faces of the output shaft heads, the square structure enables bolt connection to be more reliable, bolts are prevented from loosening, and the square structure is simpler to form in the production process.
In the embodiment, a proper amount of grease is filled in the oil grooves, the base shell is fixed on the oil grooves on the two sides of the gear part, the oil grooves are matched with the base for use, and then the photovoltaic module is installed on the output shaft head and connected together for use.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
In summary, the present invention achieves the design objectives.
