Abstract
The utility model discloses a reduction gearbox which mainly consists of a box body, an upper cover, a secondary reduction gear, a bearing and an output shaft. The reduction gearbox is characterized in that a semi-circular groove for mounting a support rod is respectively arranged at the connection parts of the box body and the upper cover, and flanges are arranged at the two sides of the semi-circular groove. The utility model also discloses an impeller type oxygen enricher with the reduction gearbox. The support rod of the oxygen enricher is arranged in a round hole formed by the semi-circular groove of the upper cover and the semi-circular groove of the box body. The other end of the support rod is provided with a flat floating body which enables the oxygen enricher to be floated on the water surface, and the planes of two sides of the flat floating body are parallel to the support rod. Therefore, the resistance of the floating body to water flow is reduced when the oxygen enricher works, and the oxygen enriching efficiency is improved.

In the above-mentioned speed reducer half slot positioning boss is arranged.
Above-mentioned speed reducer loam cake and motor lower end cap are made one.
Above-mentioned speed reducer, the driver pinion of secondary driving gear is contained on the motor shaft, drive the one-level driven gear, one-level driven gear and shaftgear combination drive the secondary driven gear, the upper end bearing of shaftgear is in the bearing chamber of loam cake, bottom end bearing is in the bearing chamber of casing, and the bearing chamber outer end is sealed.
There is closed chamber above-mentioned speed reducer casing lower end, and closed chamber and casing are made one.
The paddle aerator that has this speed reducer, strut are installed in the circular hole that the half slot of the half slot of loam cake and casing forms.
Strut one end of above-mentioned paddle aerator is jagged, and breach and positioning boss cooperate.
On the half slot of the loam cake of above-mentioned paddle aerator hexagon ring is arranged, the hexagon head of the hex head bolt of fastening strut passes the hexagon ring of loam cake, is fixed on strut and the casing.
The other end of the strut of above-mentioned paddle aerator has the flat buoyancy aid that aerator is floated on the surface.
The end of the strut of above-mentioned paddle aerator and flat buoyancy aid junction plane have the buoyancy aid retainer ring, and be fluted in the retainer ring, and convex tendon is arranged on the buoyancy aid, the groove fit in convex tendon on the buoyancy aid and the retainer ring.
The present invention is not the simple material replacement that aluminium is replaced iron compared to existing technology, and outstanding advantage is:
1. the method that original whole sand rotating tooth roller box is used instead alloy aluminum die casting extrudes half slot and the closed chamber of placing strut simultaneously, and machining is become simply, realizes cutting less or not having cutting, is fit to production in enormous quantities.
2. save parts such as bearing chamber cap and closed chamber.
3. complete machine weight is reduced, can reduce the volume of buoyancy aid, the resistance to water-flow when flat buoyancy aid reduces aerator work improves oxygenation efficient; The easy closed assembly of flat buoyancy aid, reduction packed and transported cost.

Embodiment
With specific embodiment the present invention is further described below, referring to Fig. 1-8:
A kind of alloy aluminum die casting speed reducer of paddle aerator mainly by: casing 2, loam cake 1, double-reduction gear, bearing, output shaft 10 etc. are formed, respectively there are three half slots that strut 21 can be installed the junction of casing 2 and loam cake 1, half slot is uniform with three equal parts, casing 2 and loam cake 1 usefulness bolt 23 fit sealings.Two half slots become a circular hole, and strut 21 is contained in the circular hole, and are accurate for the location of strut 21 in circular hole, are shaped on positioning boss 27 in half slot, are shaped on breach 28 in strut 21, and breach 28 and positioning boss 27 match.The hexagon head of hex head bolt 22 passes the hexagon ring 15 of loam cake 1, and screw rod and nut make casing 2 and strut 21 fastening.Respectively there is flange 13 junction of casing 2 and loam cake 1, and flange 13 improves the twisting resistance intensity of half slot in the both sides of half slot.Loam cake 1 and motor lower end cap 17 can be made into one, and the driving gear 5 of double-reduction gear is contained on the motor shaft 26, drive one-level driven gear 6, one-level driven gear 6 and shaftgear 7 coaxial drive secondary driven gears 8, and secondary driven gear 8 drives output shaft 10.The upper end bearing 12 of shaftgear 7 is in the bearing chamber of loam cake, and bottom end bearing 11 is in the bearing chamber 14 of casing 2, and bearing chamber 14 outer ends are sealed, and can save bearing cap.There is closed chamber 9 casing 2 lower ends, and closed chamber 9 and casing 2 are cast into one, need not adorn closed chamber in addition.
A kind of paddle aerator that has alloy aluminum die casting speed reducer, because alloy aluminum die casting speed reducer weight reduces significantly, the less flat buoyancy aid 19 of the other end available volume of strut 2 is kept afloat aerator, the plane, both sides of flat buoyancy aid 19 is parallel with strut 21, buoyancy aid reduces the resistance of current when making aerator work, improves oxygenation efficient.For the assembly direction of flat buoyancy aid 19 and strut 21 is reliably located, the end of strut 21 and flat buoyancy aid 19 junction planes have buoyancy aid retainer ring 20, are shaped on groove 25 in the retainer ring 20, on the flat buoyancy aid 19 convex tendon 24 are arranged, convex tendon 24 and groove 25 cooperate, and make the directed installation of flat buoyancy aid.Flat buoyancy aid 19 technology capabilities are good, transportation and packing cost reduce.
The foregoing description is one of preferred embodiment of the present invention only, is not to limit protection scope of the present invention according to this, so: all equivalences of doing according to structure of the present invention, shape, principle change, and all should be covered by within protection scope of the present invention.
