Description
Technical field
The present invention relates to the large diameter combined support raceway worm type of reduction gearing of one kind, various drivers are widely used in
The azimuth transmission of structure, particularly solar power generation tracker is used.
Background technology
At present, in the tracking power station azimuth transmission of solar power generation, a large amount of worm gear snails using pivoting support structure
Bar decelerator, its advantage is big gearratio, stable drive, can bear axial force, radial load and tilting moment with self-locking,
Have the disadvantage：1st, the characteristics of azimuth is driven is to need larger tilting moment and less driving torque, and uses pivoting support
The inner side that its swiveling gear of the decelerator of structure is enclosed outside in the outside of pivoting support outer ring, support raceway, larger power of tumbling
Square needs larger back-up roller road size, although less driving torque does not need larger gear size, structures shape
Larger gear size, it is bigger than normal to thus result in decelerator size, pivoting support complex structure, high cost；2nd, rotation supporting structure
Decelerator sealing difficulty it is big, sealing life is low, poor reliability.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of large diameter combined support raceway worm and gear slows down
Device, its back-up roller road size is larger, and travelling gear size is smaller, can reach and overcome larger tilting moment and less torsion
The purpose of torque demand, while the characteristics of there is sealed reliable, compact conformation.
The object of the present invention is achieved like this：A kind of large diameter combined support raceway worm type of reduction gearing, it is wrapped
Pedestal is included, the pedestal includes axle housing and the seat ring being connected with axle housing, worm gear gear ring, the axle are provided with the seat ring
Worm screw is provided with shell, the worm gear gear ring is meshed with worm screw, the worm gear gear ring lower section is provided with end cap, and the end cap leads to
Cross bolt to be fixedly connected with worm gear gear ring, support raceway is provided between the worm gear gear ring and end cap and seat ring bottom, it is described
Track is provided with support raceway, steel ball is provided with the track.
The seat ring upper surface is vexed plate.
Seat ring upper surface center offers first through hole, and the first through hole extends downward with connecting portion, institute
State worm gear gear ring center and offer the second through hole, the connecting portion is inserted in the second through hole, the connecting portion and worm gear gear ring it
Between be provided with seal.
Sealing ring is provided between the end cap and seat ring, the sealing ring is located at track lower section.
Compared with prior art, the invention has the advantages that：
A kind of large diameter combined support raceway worm type of reduction gearing of the invention, its back-up roller road size is larger, and passes
Moving gear size is smaller, can reach the purpose for overcoming larger tilting moment and less torsional moment demand, makes compact conformation,
Low cost of manufacture；Seal is placed in inside decelerator simultaneously, is difficult to be influenceed by external environments such as ultraviolet and ozone, is improve and is subtracted
The service life of fast device.
