Background technique

Aerator is the equipment that in the aquaculture fishes and shrimps is had lifesaving and growth encourage, and the prior mechanical aerator mainly contains Waterwheel-type, impeller type and water jet three major types type, and wherein waterwheel aerator uses wider.Original waterwheel aerator all has the shell of whole speed reducer, and the shell casting and the processing of whole speed reducer are all inconvenient, the cost of production height.As Chinese patent 00235021.1 waterwheel aerator, adopt the curved tooth transmission, the speed reducer that substitutes original worm and gear transmission has improved dynamic efficiency, but the shell of speed reducer is a cast-in-block, whole shell can't be used the contour efficient explained hereafter of die casting.

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 speed reducer easily manufactured, cost reduces.

The object of the present invention is achieved like this:

A kind of combined speed reduction box of water-mill oxygen increasing machine, the speed reducer housing by about half shell combination be shaped, the platform that connects vertical machine is arranged on half housing, vertical machine by vertical installation drives bevel pinion, bevel 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, speed reducer by about half housing form, housing is stretched out by motive 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 junction plane of two halves housing has flange, on the flanged surface 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 on 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.

The water-mill oxygen increasing machine that has this speed reducer, a horizontal buoyancy aid and a vertical buoyancy aid are formed, and vertical buoyancy aid has a mounting plane, is installed in the central composition T type buoyancy aid of horizontal buoyancy aid, speed reducer is installed on the vertical buoyancy aid by footing, and the two ends output shaft is by the connecting sleeve impeller.

Outstanding compared to existing technology substantive distinguishing features and the obvious improvement of the present invention is:

1. the individual cast of speed reducer housing can be adopted aluminum alloy and Cuprum alloy casting forming, the manufacturing efficiency height, and any surface finish, attractive in appearance, 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 height, fitted position be stable;

Bearing cap can with half housing cast solid, the speed reducer part is reduced;

4. reduce significantly when the aluminum hull speed reducer is heavier than cast iron speed reducer, can subtract pontoon quantity and volume, provide implementation condition in particular for buoyancy aid and the closed assembly impeller of implementing the T type.
