Description
Technical field
The utility model relates to a kind of large diameter combined support raceway worm type of reduction gearing, is widely used in various driving mechanism, and particularly the azimythal angle transmission of solar electrical energy generation tracker is used.
Background technique
At present, in the tracking power station azimythal angle transmission of solar electrical energy generation, the worm type of reduction gearing of a large amount of employing pivoting support structure, its advantage is that velocity ratio is large, stable drive, can self-locking, axial force can be born, radial force and tilting moment, shortcoming is: 1, the feature of azimythal angle transmission needs larger tilting moment and less driving torque, and adopt the outside of its swiveling gear of retarder in pivoting support outer ring of pivoting support structure, support the inner side that raceway encloses outside, larger tilting moment needs larger back-up roller road size, although less driving torque does not need larger gear size, but the larger gear size of structures shape, thus cause retarder size bigger than normal, pivoting support complex structure, cost is high, 2, the retarder sealing difficulty of rotation supporting structure is large, and sealing life is low, poor reliability.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of large diameter combined support raceway worm type of reduction gearing is provided, its back-up roller road size is larger, and driving gear size is less, the object overcoming larger tilting moment and less torsional moment demand can be reached, have simultaneously and seal feature that is reliable, compact structure.
The purpose of this utility model is achieved in that a kind of large diameter combined support raceway worm type of reduction gearing, it comprises pedestal, the seat ring that described pedestal comprises axle housing and is connected with axle housing, worm gear gear ring is provided with in described seat ring, worm screw is provided with in described axle housing, described worm gear gear ring is meshed with worm screw, end cap is provided with below described worm gear gear ring, described end cap is fixedly connected with worm gear gear ring by bolt, described worm gear gear ring and be provided with support raceway between end cap and seat ring bottom, track is provided with in described support raceway, steel ball is provided with in described track.
Described seat ring upper-end surface is vexed plate.
Center, described seat ring upper-end surface offers the first through hole, described first through hole is extended downwards joint, described worm gear gear ring center offers the second through hole, and described joint inserts in the second through hole, is provided with Sealing between described joint and worm gear gear ring.
Be provided with seal ring between described end cap and seat ring, described seal ring is positioned at below track.
Compared with prior art, the utility model has following beneficial effect:
A kind of large diameter combined support raceway worm type of reduction gearing of the utility model, its back-up roller road size is comparatively large, and driving gear size is less, can reach the object overcoming larger tilting moment and less torsional moment demand, make compact structure, low cost of manufacture; Sealing is placed in retarder inside simultaneously, is not subject to the impact of the external environment such as ultraviolet and ozone, improves the working life of retarder.
