Description
Technical field
This utility model belongs to reductor technical field, particularly to roller oscillating tooth gear decelerator.
Background technology
At present, the decelerator used on the tracker of solar energy azimuth is swinging reductor, and it is by worm screw
Drive worm gear forms, by engaging each other transmission between tooth and tooth.Solar energy azimuth tracker uses
The decelerator of said structure has a disadvantage in that owing to solar tracker is disposed in the outdoor, and bears during work
Wind, avenge and various load that deadweight etc. causes, and magnitude of load is uncertain, the moment of torsion born in work
Change is big so that the tooth of turbine and worm is fragile so that the service life of decelerator is low, according to statistics,
Reductor works under this operating mode, and its average life is 3-5, if changing not in time, solar energy chases after
Track device cisco unity malfunction.Therefore the working service to solar energy proposes the highest requirement, which limits
The using and promoting of solar energy.
Utility model content
The purpose of this utility model is for using prior art decelerator for solar energy azimuth tracker
Time, service life is short, need to carry out the deficiency regularly replaced, it is provided that a kind of service life is long, can bear big torsion
The variator of square.
The purpose of this utility model is achieved by the following technical solution:
A kind of roller oscillating tooth gear decelerator, including power shaft, output shaft, housing, cylindrical roller and drive end bearing bracket,
Power shaft is rotationally connected with drive end bearing bracket, also includes pivoting support, and drive end bearing bracket is fixing with the outer ring of pivoting support to be connected
Connecing, output shaft is fixing with the inner ring of pivoting support to be connected；
Described pivoting support is bearing；
Being provided with eccentric segment on described output shaft, the end face of output shaft arranges retainer, cylindrical roller is arranged
In gear hobbing groove on retainer, the eccentric segment of output shaft is by shock wave bearing and cylindrical roller and table in housing
The envelope surface that face is arranged rolls and connects, and output shaft and power shaft are rotationally connected.
Use the decelerator of this utility model structure, use roller oscillating tooth gear reductor that solar energy azimuth is carried out
Chase after comprehensive, owing to roller oscillating tooth gear reductor is multiple tooth engaged transmission, therefore the moment of torsion that decelerator is subject to can be divided
Being scattered on multiple tooth, the moment of torsion that each tooth bears greatly reduces so that the decelerator life-span is long, again due to by returning
The outer ring or the inner ring that turn supporting are rotationally connected with drive end bearing bracket, and inner ring or outer ring by pivoting support turn with output shaft
Being dynamically connected, therefore, output shaft rotating accuracy is high, can react the bearing signal received exactly, make the sun
Energy cell panel is followed the trail of the accuracy of track of sun and is significantly improved.

Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:
As Fig. 2 combines shown in Fig. 1, decelerator of the present utility model is roller oscillating tooth gear decelerator, and it includes defeated
Enter axle 10, output shaft 7, housing 8, cylindrical roller 9 and drive end bearing bracket 3.Power shaft 10 is provided with eccentric shaft
Section and supporting section one and supporting section two, supporting section one and supporting section two set up the both sides at eccentric shaft part separately；Output
One end of axle 7, for connecting end, is connected with load, and the other end is abutting end, and abutting end is provided with ring-type convex
Playing 14 and mating holes 1, arrange gear hobbing groove 13 on annular projection, gear hobbing groove is circumferentially disposed on
On the end face of the abutting end of output shaft 7, the annular projection 14 being provided with gear hobbing groove forms receiving cylindrical roller 9
Roller cage, cylindrical roller 9 is arranged in gear hobbing groove；Housing 8 is provided with endoporus, endoporus table
Face is the enveloping surface of curved surface, referred to as cylindrical roller, and output shaft 7 is bent with the envelope of housing by cylindrical roller 9
Face is connected, and power shaft 10 is connected with the cylindrical roller arranged on output shaft by shock wave bearing 4, input
Axle is rotationally connected by mating holes 1, supporting section one and intermediate bearing 6 with output shaft, and power shaft passes through it
Supporting section two and input shaft bearing 1 are rotationally connected with drive end bearing bracket 3, bearing gland 2 carry out input shaft bearing 1
Fixing.So, the roller cage of output shaft 7 is embedded in the endoporus of housing 8, and the support of power shaft
Section one is embedded in the mating holes one of output shaft rotationally, and the eccentric segment of power shaft is embedded in retainer rotationally
In, housing is fixing with drive end bearing bracket to be connected, and bearing gland is fixedly installed on drive end bearing bracket；Output shaft 7 and revolution
The inner ring 11 of supporting 5 is fixing to be connected, and drive end bearing bracket 3 is fixing with the outer ring 12 of pivoting support 5 to be connected, so
Setting can dramatically increase the transmission accuracy of decelerator.Pivoting support by inner ring 11 and outer ring 12 by roller or
Ball rolls or is rotationally connected composition, preferably cylinder roller bearing or ball bearing.Power shaft, output shaft,
Pivoting support and housing 8 female coaxial are arranged.The inner ring of pivoting support, outer ring and power shaft and output shaft
It is coaxially disposed.
During work, power shaft rotates, and under the effect of its eccentric shaft part, shock wave bearing promotes cylindrical roller radially
Displacement, owing to housing maintains static, inner ring is connected with outer ring rotating, and inner ring is fixing with output shaft to be connected, outward
Enclose be connected fixing with drive end bearing bracket, therefore promote output shaft rotation, reach the purpose slowed down, due in this process
In, power shaft and output between centers are by cylindrical roller and its envelope surface transmission, in the bias of eccentric shaft
Under effect, there is the cylindrical roller of half to participate in transmission all the time, therefore, be distributed to the power on each cylindrical roller
Square is little, and decelerator can bear big wind load, and gear ratio is big, again owing between power shaft, output shaft and housing being
Embedded connection, decelerator volume is little, it is possible to reduce the volume and weight of tracker, compact conformation, takies
Space is little, the inner ring of pivoting support be supported fixing to output shaft, and the rotating accuracy of output shaft is high, carries
The high transmission accuracy of reductor.
This roller oscillating tooth gear decelerator is particularly well-suited to the azimuthal tracking of solar tracking device.
