Background technique
Currently, in the flat uniaxial power generation tracking system of solar energy, a large amount of rotary reducers for using pivoting support structure,
It is mainly characterized by that roller path structure, stable drive are reliable, accuracy class is high.Flat uniaxiality tracking retarder output end one common at present
As use single sealing strip or rotary shaft lip seal sealing means, the effect of the sealing means water proof and dust proof of sealing strip
It is poor；Although rotary shaft lip seal has preferable water proof and dust proof effect, when sealing ring passes through long-term ultraviolet light
After irradiation and rain drop erosion, poor sealing will cause, rainwater penetrates into inside device from sealing place to be caused to get rusty and failure of apparatus.
Utility model content
Technical problem to be solved in the utility model is that a kind of multi-sealed type revolution is provided for the above-mentioned prior art
Deceleration device, the sealing means that output end uses rotary shaft lip seal to combine with sealing strip, and set on the top of pedestal
It is equipped with the eaves of rain cover, is penetrated into inside device after preventing rainwater from directly washing away to sealing element.Outside pedestal inner cavity, gear shaft
It is respectively arranged with raceway on circle, it is not necessary that floating bearing is separately provided, reduces the cost of device and easy to assembly.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of multi-sealed type slewing reduction apparatus,
It includes pedestal, and the pedestal includes axle housing and seat ring, and worm screw is provided in the axle housing, is provided with gear in the seat ring
Axis, the worm screw are meshed with the gear on gear shaft, are provided with interior rollaway nest on the seat ring inner cavity, on the gear shaft outer ring
It is provided with outer rollaway nest, steel ball, former and later two output ends and seat of the gear shaft are provided between the interior rollaway nest and outer rollaway nest
It is provided with rotary shaft lip seal between circle, is provided with sealing strip on the outside of the rotary shaft lip seal.
Locking nut and end cap are provided at left and right sides of the worm screw, the end cap is connected by clamping screw with axle housing
It connects.
Front and rear sides are provided with eaves at the top of the pedestal.
The eaves is formed with pedestal integral cast.
Compared with the prior art, the advantages of the utility model are:
A kind of multi-sealed type slewing reduction apparatus of the utility model, is combined using rotary shaft lip seal with sealing strip
Sealing means, and the eaves of rain cover is set at the top of pedestal, is respectively arranged on pedestal inner cavity and gear shaft outer ring
Raceway has the characteristics that simple, at low cost, the multi-sealed protection of structure, while curstomer's site is easy for installation, maintenance is simple, can
The cost of tracking system is effectively reduced.
