Summary of the invention

The objective of the invention is to solve the deficiency of existing water-mill oxygen increasing machine, a kind of combined speed reduction box of water-mill oxygen increasing machine is provided, make reduction box easily manufactured, cost.

The object of the present invention is achieved like this:

A kind of combined speed reduction box of water-mill oxygen increasing machine, reduction box casing by about half shell combination be shaped, the platform that connects vertical machine is arranged on half housing, vertical machine by vertical installation drives cone pinion, cone pinion drives large bevel gear, large bevel gear is fixed on the axle of small cylinder gear, small cylinder gear drives the big column gear, big column gear driven output shaft, output shaft is exported from two and half housing basic horizontal, reduction box by about half housing form, housing is stretched out by movable sealing in the output shaft two ends.

A kind of combined speed reduction box of water-mill oxygen increasing machine, housing are by casting forming, and the faying face of two halves housing has flange, on the flange face of one of them half housing sealing are arranged.

A kind of combined speed reduction box of water-mill oxygen increasing machine, the side of one of them half housing is shaped with tank filler sleeve.

A kind of combined speed reduction box of water-mill oxygen increasing machine, the bearing chamber outer end of small cylinder gear seals, and does not have the bearing chamber cap.

Water-mill oxygen increasing machine with this reduction box, a horizontal buoyancy aid and a vertical buoyancy aid form, and vertical buoyancy aid has a mounting plane, is installed in the T-shaped buoyancy aid of central composition of horizontal buoyancy aid, reduction box is installed on the vertical buoyancy aid by footing, and the two ends output shaft is by the adapter sleeve impeller.

The substantive distinguishing features that the present invention gives prominence to compared to existing technology and significant progress are:

1. the reduction box casing individual cast can be adopted aluminium alloy and copper alloy casting forming, and production efficiency is high, any surface finish, attractive in appearance, and the diameter of gear is not subjected to motor to cooperate the restriction of mouthful size;

2. half housing separate machined can be raised the efficiency about, machining accuracy is high, fitted position is stable;

Bearing cap can with half housing cast solid, the reduction box part is reduced;

4. decrease when the aluminum hull reduction box is heavier than cast iron reduction box can subtract pontoon quantity and volume, provides implementation condition in particular for implementing T-shaped buoyancy aid and closed assembly impeller.
