Description
Technical field
The invention belongs to solar energy tracking technical field, a kind of more particularly to maintenance-free dry for solar tracking is run back
Turn supporting structure.
Background technology
At present, pivoting support structure is widely used in solar energy tracking field, and as illustrated in fig. 1 and 2, motor 2 drives snail
Bar 3 is rotated, and worm screw 3 drives turbine rotation, and worm screw is fixed by the taper roll bearing 8 installed in its both ends with housing 1, with limit
The axially and radially motion of worm screw processed, and only retain rotation, so as to realize the relative rotation relation between housing and turbine, finally
Reach the purpose of the driving solar elements alignment sun.
Worm screw is with must have lubrication, generally use lubricating grease profit in said structure in turbine and taper roll bearing
Sliding, because the structure place to use is all in more remote open air, environment is more severe, and it is very inconvenient to safeguard, plus sleet, dust storm
Deng the effect of natural environment, lubricating grease will typically fail in 3 to 5 years, so as to cause equipment fault.
The content of the invention
It is an object of the invention to：For above-mentioned problem, there is provided one kind can thoroughly solve because of lubrication failure and
The maintenance-free dry for solar tracking to break down runs pivoting support structure.
The technical proposal of the invention is realized in this way：A kind of maintenance-free dry for solar tracking runs pivoting support knot
Structure, including housing, motor and be arranged in housing and intermeshing worm screw and turbine, the worm screw and motor
Clutch end is connected, and left and right gland is provided with housing corresponding to the worm screw both ends, it is characterised in that：Described left and right
The left and right step sliding shaft sleeve of engineering plastics manufacture is respectively arranged between gland and worm screw, the left and right step is slided
Axle sleeve forms overall structure, the inwall of the left and right step sliding shaft sleeve and snail with corresponding left and right gland tight fit respectively
Bar is bonded, and the worm screw can rotate relative to left and right step sliding shaft sleeve, and the left and right gland slides left and right step
Moving axis set is pressed on corresponding to worm screw both ends at ledge structure, is noted in the flank of the worm screw or turbine using engineering plastics
Modeling has composite bed.
Maintenance-free dry of the present invention for solar tracking runs pivoting support structure, and it is in the left and right step
Sealing structure is respectively arranged with the outside of formula sliding shaft sleeve, between worm screw and left and right gland.
The present invention is by the analysis to sun tracker operational mode, in combination with modern project plastics and complex technique
Feature, to having done maintenance-free dry operating energy loss for the pivoting support of solar tracking, it is allowed to thoroughly break away from the tired of lubrication failure
Disturb, ensure its operation reliably and with long-term, single worm structure of the design can use available for the requirement of low tracking accuracy, twin worm structure
In high precision tracking.
Brief description of the drawings
Fig. 1 is the structural representation of existing pivoting support.
Fig. 2 is A-A sectional views in Fig. 1.
Fig. 3 is the structural representation of the present invention.
Marked in figure：1 is housing, and 2 be motor, and 3 be worm screw, and 4a is left gland, and 4b is right gland, and 5a is left step
Formula sliding shaft sleeve, 5b are right step sliding shaft sleeve, and 6 be ledge structure, and 7 be sealing structure, and 8 be taper roll bearing.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in figure 3, a kind of maintenance-free dry for solar tracking runs pivoting support structure, including housing 1, driving electricity
Machine 2 and it is arranged in housing 1 and intermeshing worm screw 3 and turbine, the worm screw 3 connect with the clutch end of motor 2
Connect, left gland 4a and right gland 4b are provided with housing 1 corresponding to the both ends of worm screw 3, in the left and right gland and worm screw 3
Between be respectively arranged with engineering plastics manufacture left step sliding shaft sleeve 5a and right step sliding shaft sleeve 5b, it is described left and right
Step sliding shaft sleeve forms overall structure, the left and right step sliding shaft sleeve with corresponding left and right gland tight fit respectively
Inwall be bonded with worm screw 3, and the worm screw 3 can rotate relative to left and right step sliding shaft sleeve, and the left and right gland will
Left and right step sliding shaft sleeve is pressed on corresponding to the both ends of worm screw 3 at ledge structure 6, in the worm screw 3 or the screw thread of turbine
Face is molded with composite bed using engineering plastics.
Wherein, it is respectively arranged with sealing on the outside of the left and right step sliding shaft sleeve, between worm screw 3 and left and right gland
Structure 7, to ensure the sealing state in housing.
The sun tracker speed of service is very slow, and once, normal tracking is tracked the average movement in every 4 minutes of the sun using gap
The circle of operation one daily, linear velocity is very low between worm screw during operation, and its speed of service is typically in 0.01m/s or so, each run
Typically in 5 seconds, heating and abrasion are all very low, simultaneously because tracker solar elements General Central is all in pivoting support
Center, therefore driving force is lifted also very low, and engineering plastics are easy to be molded, cheap, have good low rate start performance
And it is very low and non-maintaining in total life cycle to water and dirt sensitivity, it can reach different by different packing materials
Environment needs, and between existing engineering plastic bearing compressive property can accomplish 50~200Mpa, fully meets design requirement.
Wherein, set respectively on the screw mandrel 2, on the outside of left step sliding shaft sleeve 6a and right step sliding shaft sleeve 6b
There are a left set thrust plate 7a and right set thrust plate 7b, left and right step sliding shaft sleeve is fixed to radial and axial and retains rotation
Transhipment is dynamic, and sleeve lining undertakes radial load, and axle sleeve step bears axial force with set thrust plate, is threadedly coupled on the screw mandrel 2
There is gap to adjust retaining ring 8, adjust retaining ring by running clearance slides with left and right step respectively to left and right set thrust plate
Locked after being adjusted in the gap of axle sleeve, it is ensured that the rational running clearance of screw mandrel.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
