Description
Technical field
The utility model relates to a kind of retarder, is widely used in the transmission use occasion that should horizontally rotate, vertically rotate again, is specially adapted to the use field of solar tracker.
Background technique
Aspect solar electrical energy generation, in order to improve generating efficiency, will make solar energy photographic plate vertical surface towards the sun, thereby require the solar energy photographic plate should horizontally rotate vertical rotation again, with sun-tracing from the east to the west with the height variation, the solar energy photographic plate also will bear the external force of blizzard in addition, needs driving mechanism can bear bigger load.Its driving mechanism mainly contains following several at present:
1, installs with rotary decelerator level and realize that the solar energy photographic plate horizontally rotates, push away or draw the solar energy photographic plate to make its vertical rotation with an electric pushrod.Shortcoming is that structure is loaded down with trivial details, and when design and installation fee, electric pushrod can not bear bigger load, and using has certain narrow limitation.
2, with a rotary decelerator level realization solar energy photographic plate is installed and is horizontally rotated, vertically install with another rotary type speed reducer and realize that the solar energy photographic plate vertically rotates.Advantage is because rotary type deceleration function is born bigger load, makes the device of solar generating reliable operation.Shortcoming is to have two speed reducers to need mounting arrangements, complex structure, cost height.
The patent No. is that the technological scheme of 200920040149.7 publicities has adopted the combined type rotary speed reducer, can bear than the high pulling torque load, has the function that horizontally rotates with vertical rotation again simultaneously, and simple in structure, has reduced manufacture cost.But solar tracker has higher requirement to transmission accuracy, because the centre distance of its worm and gear can not be adjusted, wants to realize the little back lash transmission of degree of precision, can only improve the quality of processing of component, thereby manufacture cost is higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of adjustable center distance twocouese rotation worm type of reduction gearing is provided, can realize the little back lash transmission of degree of precision, and it is simple in structure, low cost of manufacture, can bear bigger load, have the function that horizontally rotates with vertical rotation simultaneously again.
The purpose of this utility model is achieved in that a kind of adjustable center distance twocouese rotation worm type of reduction gearing, it comprises pedestal, worm screw, solid of rotation and end cap, described pedestal comprises axle housing and seat ring, described axle housing and seat ring fuse, described axle housing and seat ring respectively have two, the shaft axis of described two axle housings is setting parallel to each other in the spatial position, the shaft axis of described two seat rings is orthogonal setting in the spatial position, described worm screw has two, two worm screws are arranged in two axle housings of pedestal respectively by bearing, described solid of rotation is made up of external toothing and bearing, described external toothing has two, two external toothings are meshing with each other with two worm screws respectively, and described end cap has two, is characterized in: described retarder also comprises mandrel, described mandrel has two, two mandrels are fixedly connected on a side of two seat rings respectively by adjusting screw, and described two external toothings are installed in respectively on two mandrels by bearing, and described two end caps are fixedly connected on an end of described two mandrels respectively.
Compared with prior art, the beneficial effects of the utility model are:
A kind of adjustable center distance twocouese rotation of the utility model worm type of reduction gearing, its external toothing by Bearing Installation on mandrel, and mandrel is connected seat ring one end by screw, can be during installation by adjusting the centre distance that worm and gear is regulated in mandrel and the position of worm screw, the little back lash transmission of realization degree of precision.
