Abstract
The utility model provides an improved worm speed reducer for a photovoltaic power-generating single-shaft tracking system, which is simple in structure, can effectively solve the problem that a shaft key is damaged under the action of the wind impact load, is short in the seal line, and is low in the drive energy consumption. The improved worm speed reducer comprises a base, a worm and a rotary worm gear, wherein the worm and the rotary worm gear are arranged in the base; and the worm is mutually meshed with the rotary worm gear. The improved worm speed reducer is characterized in that the base are provided with a through hole flange and a blind hole flange along the axial two ends of a rotating shaft of the tracking system, the two ends of a worm gear shaft of the rotary worm gear are respectively fixed at the through hole flange and the blind hole flange by a rolling bearing, one end of the worm gear shaft penetrates through the through hole flange to be fixed on a bracket at one end of the single-shaft tracking system, and the blind hole flange is connected with the rotating shaft of the single-shaft tracking system.

Technical field
The utility model relates to the photovoltaic power generation technology apparatus field, is specially a kind of improved worm type of reduction gearing that is used for the photovoltaic generation single-shaft tracking system.
Background technique
At present in the driving mechanism of the photovoltaic generation uniaxiality tracking sun, because of the worm and gear transmission has that velocity ratio is big, stable drive, can self-locking etc. characteristics be widely applied.Present worm type of reduction gearing has two kinds of structures, a kind of is that tracking system rotatingshaft 1 two ends that solar array is installed adopt bearing 2 to support, see accompanying drawing 1, the pedestal 3 of worm type of reduction gearing is fixing with the bearing support 6 of an end wherein, thereby the output shaft of worm type of reduction gearing is connected the drive rotatingshaft with tracking system rotatingshaft 1 by axle key 4 and solar array rotates, to follow the tracks of the sun, its shortcoming is axle key 4 easy damaged under the effect of wind-force impact load, makes solar battery array rock the gap and becomes big gradually; And its complex structure, its tracking system rotatingshaft supports by bearing 2, and worm-wheel shaft 7 is also supported by bearing 8 self, has adopted two groups of bearing block structures, and structure repeats, the cost height; Another structural type, see accompanying drawing 2, worm type of reduction gearing is flange output, and its output flange 9 directly is connected with tracking system rotatingshaft 1, worm type of reduction gearing pedestal 3 is as the support of rotatingshaft 1 one ends, though the supporting bearing base that it has been avoided the damage problem of axle key connection and has save rotatingshaft one end, because output flange is the body of worm gear, diameter is bigger, the seal diameter of packing grease is bigger, potted line is longer, so surface friction drag is bigger, drives the energy consumption height.Among Fig. 1 and Fig. 2,12 is solar panel.
Summary of the invention
At the problems referred to above, the utility model provides a kind of improved worm type of reduction gearing that is used for the photovoltaic generation single-shaft tracking system, and it is simple in structure, can effectively solve the problem of axle key damage under the wind-force impact loading, and potted line is short, and it is low to drive energy consumption.
Its technological scheme is such, it comprises pedestal, worm screw and revolution worm gear, described worm screw is installed in the described pedestal with the revolution worm gear, described worm screw and described revolution worm gear are meshing with each other, it is characterized in that: described pedestal is equipped with through hole flange and blind hole flange along the axial two ends of tracking system rotatingshaft, described through hole flange and blind hole flange are fixed in by rolling bearing respectively in the worm-wheel shaft two ends of described revolution worm gear, described worm-wheel shaft one end passes described through hole flange and is fixed on the support of single-shaft tracking system one end, and described blind hole flange is connected with the rotatingshaft of single-shaft tracking system.
It is further characterized in that: described pedestal comprises the worm screw shell and constitutes the seat ring of one with described worm screw shell; Described worm screw is installed in the described worm screw shell; Described revolution worm gear is positioned at described seat ring; Described through hole flange and blind hole flange are installed on the two ends of described seat ring respectively.
A kind of improved worm type of reduction gearing that is used for the photovoltaic generation single-shaft tracking system of the present utility model, its pedestal is connected with the tracking system rotatingshaft by blind hole flange, effectively avoided the flimsy problem of the strong connection of axle in the past, and its worm-wheel shaft through hole flange directly is supported on the support of tracking system rotatingshaft one end, the bearing support that has reduced by an end supports, and simplifies the structure; And it has only a shaft sealing, and potted line is shorter, and surface friction drag is little, can reduce to drive energy consumption.
