Design scheme: in order to realize above-mentioned purpose of design.The utility model in structure design, using double lead worm gear poles
The design of structure is one of the technical characteristics of the utility model.The purpose of this design is: double lead worm and gear sideshake tune
Whole to can be as small as 0.01~0.015mm, conventional worm worm gear pair can only be up to 0.03~0.08mm, therefore, double lead worm and gears
Pair can work under lesser sideshake, this is highly beneficial to the indexing accuracy for improving NC rotary table, and common worm screw is
Moved radially with worm screw along worm gear to adjust meshing backlass, thus change the center of transmission away from (center away from change can draw
Face situation variation or even unstable wear are played, is unfavorable for keeping the precision of worm gear), the application is using double lead worm gears
Worm screw is to adjust meshing backlass with worm screw axial movement, will not change the center of transmission away from can fundamentally avoid
State disadvantage；Secondly, double lead worm and gears are to control adjustment amount with reconditioning adjustment ring, adjustment is accurate, convenient and reliable, and common
The more difficult grasp of radial adjustment amount of worm gear, when adjustment, are also easy to produce worm axis skew；Third is that double lead worm and gear ratios
It is more special, since the lead of tooth left and right sides is different, thus the characteristics of form transverse tooth thickness even variation.2, upper box, lower box
Left oil sealing and right oil sealing between Zuo Falan, right flange use the setting of spring-piece type oil enveloping structure, are the skills of the utility model
The two of art feature.The purpose of this design is: be suitable for the severe outdoor environment such as dust storm, can effectively prevent dust into
Enter, reduces the abrasion of oil sealing, the service life of prolonged deceleration machine.
Technical solution: a kind of double lead dual-axis rotation speed reducers for tower photo-thermal power generation heliostat, upper box is under
Cabinet is locked into one, and the double lead worm gears in top form floating bearing system by orbit of steel wire bearing and upper box, right flange, left
Flange and right flange are locked on the double lead worm gears in top, and input power is transferred to upper double lead snails after being slowed down by planetary reducer
Bar makes worm gear, Zuo Falan, right flange rotary, the external heliostat pitch axis of flange, so that heliostat be made to rotate around top box body axis；
The double lead worm gears in lower part form floating bearing system, base flange locking by orbit of steel wire bearing and lower box, base flange
On the double lead worm gears in lower part, input power is transferred to lower double pitch worm after being slowed down by planetary reducer, because of the double leads in lower part
Worm gear is fixed on base flange, then forces lower double pitch worm that lower box is driven to turn round around the axis of base flange, drive
Heliostat is whole to be rotated around base flange trunnion axis.
The utility model compared with the background art, first is that double using high-precision in tower photo-thermal heliostat Double-axis transmission field
Lead technology keeps speed reducer factory sideshake consistency good, and abrasion rear side gap can change worm screw axial direction by clearance adjusting device
Position is finely adjusted, and not only ensure that the transmission accuracy of heliostat, but also ensure the accurate solar tracking of heliostat；Second is that using four
The orbit of steel wire bearing of angle symmetric contact can bear radial and axial load simultaneously, have very high bearing capacity and use the longevity
Life；Third is that the fixation of left flange, right flange, base flange and worm gear is all made of the locking mode of multiple screws, screw is equipped with anti-
Loose washer effectively avoids the reasons such as vibration from causing the risk of thread looseness；Fourth is that being suitable for dust storm etc. using spring-piece type oil sealing and disliking
Bad outdoor environment effectively prevent the entrance of dust and reduces the abrasion of oil sealing, effectively the service life of prolonged deceleration machine.
