Abstract
The invention relates to a vertical reverse umbrella aerator bearing seat comprising a seat body and a main shaft, wherein an inner cavity of the seat body is provided with a pair of conical roller bearings, and two supporting points of a double-cantilever beam structure are formed by supporting a main shaft by the pair of conical roller bearings; a seat body flange is arranged at the upper end of the seat body, and a positioning boss is arranged on the lower surface of the seat body flange; the boss and a mounting flat plate are positioned and fixed; and an input end of the main shaft is connected with a speed reducer and an output end of the main shaft is connected with an aeration impeller. When the aeration impeller works, the double-cantilever beam structure formed by the main shaft and the pair of conical roller bearings bears radial force and axial force generated by rotating the aeration impeller; a load is transmitted to the seat body by taking the pair of conical roller bearings bears as the supporting points; and the seat body transmits the load borne by a bearing seat to an equipment foundation through the seat body flange and the mounting flat plate, so that the output end of the speed reducer is prevented from bearing the load, and the service life of an aerator can be effectively prolonged.
Description
Technical field
The present invention relates to the environmental protection equipment in the WWT, specifically belonging to is a kind of vertical inversed umbrella type aerator load-bearing seat.
Background technology
China is one of whole world country that water resources is the poorest per capita, and what can not be ignored is that the present water resources integral status of China has deteriorated into the condition of concerning national economy, therefore, strengthens water pollution control, is current urgent task.Biological process technology is adopted in WWT mostly, and the aeration that this technology key technology is a biological tank is oxygenation.
In the biological process oxidation ditch process, aerator generally uses the inversed umbrella type aerator, and can the steady running of inversed umbrella type aerator has influence on the entire sewage treatment process normal.
At present, the domestic and international vertical surface aeration machine of producing of falling the umbrella, step-down gear is connected with the common axle of falling the umbrella that adopts of the structure between impeller.Because aeration machine impeller when work, the radial force that stirred by water body to be produced and the axial force of impeller own wt generation make the step-down gear output terminal bear very big moving load, often cause the vibrations of aerator.In case this load exceeds the fatigue strength that is born, the bearing failure of step-down gear output terminal, aerator just can't be worked.
Summary of the invention
The object of the present invention is to provide a kind of vertical inverted umbrella-shaped aeration machine load-bearing seat; Impeller is produced when being used to bear aerator work powerful and unsettled radial force and axial force; Avoid the step-down gear output terminal to bear moving load, improved aerator work-ing life effectively.
The technical scheme that the present invention adopts is following: a kind of vertical inverted umbrella-shaped aeration machine load-bearing seat; Include pedestal and main shaft; Said pedestal inner chamber is provided with a pair of taper roller bearing, and said a pair of taper roller bearing supports main shaft forms two fulcrums of double cantilever beam structure, and said pedestal upper end is provided with the pedestal flange; The lower surface of said pedestal flange is set the position convex, said convex and the dull and stereotyped location of installation and fixing; Described main shaft input end is connected with step-down gear, and output terminal is connected with aeration impeller.
Said main shaft input end is connected with step-down gear with spline axle head or locking plate journal structure, and output terminal is stretched axle configuration taper hole flange with taper shape and is connected with aeration impeller.Be provided with bearing clearance in the middle of the main shaft and regulate screw thread; Its play of said taper roller bearing is regulated acorn nut through bearing clearance and is regulated.
Can be known by technique scheme: the present invention is provided in a side of a kind of load-bearing seat between step-down gear and impeller; Radial force and axial force that impeller produced are all acted on the load-bearing seat; Step-down gear is output torque only, avoids the influence of unsteady load to step-down gear, has improved aerator work-ing life effectively.
Description of drawings
Fig. 1 is master's TV structure synoptic diagram of the present invention.
Fig. 2 is a vertical inverted umbrella-shaped aeration machine load-bearing seat of the present invention working position synoptic diagram.
Embodiment
Like Fig. 1, shown in 2, load-bearing seat 1 comprises pedestal 1.1, main shaft 1.2, taper roller bearing 1.5, bearing clearance adjusting acorn nut 1.6.Pedestal 1.1 inner chambers have pair of bearings that shelves are installed, and a pair of taper roller bearing 1.5 is set is used for supports main shaft 1.2.There is pedestal flange 1.8 pedestal 1.1 upper ends, and the lower surface of pedestal flange is set the position convex, convex and the dull and stereotyped location of installation and fixing.Main shaft 1.2 input terminuss have spline axle head 1.3 or locking plate axle journal 1.4, and the centre has pair of bearings assembling shelves and bearing clearance to regulate screw thread, and output terminal has taper shape to stretch axle 1.7.The input terminus of main shaft 1.2 cooperates with spline axle head 1.3 and step-down gear spline syndeton 2 or locking plate axle journal 1.4 cooperates with step-down gear locking plate syndeton 3, is connected with step-down gear through this any structure formation, transmits the moment of torsion of step-down gear output; The output terminal of main shaft 1.2 has taper shape to stretch axle 1.7, and configuration taper hole flange 4 is connected with aeration impeller 5, carries the dynamic and static load of aeration impeller.Load-bearing seat 1 passes through pedestal flange 1.8 usefulness load-bearing seat standing bolts 6 to be fixed with flat board 7 is installed, and installation dull and stereotyped 7 is fixed through dull and stereotyped wall screw 8 of installation and Equipment Foundations 9, and the load that the load-bearing seat is accepted passes to Equipment Foundations.
Concrete working process is: during aeration impeller 5 work; Radial force and axial force that double cantilever beam structural bearing aeration impeller 5 rotations that formed by main shaft 1.2 and a pair of taper roller bearing 1.5 produce; This load is delivered to pedestal 1.1 through a pair of taper roller bearing 1.5 for fulcrum; Pedestal 1.1 passes through pedestal flange 1.8 to be fixed with flat board 7 is installed, and installation dull and stereotyped 7 is fixed through dull and stereotyped wall screw 8 of installation and Equipment Foundations 9, and the load that the load-bearing seat is accepted passes to Equipment Foundations; Avoid the step-down gear output terminal to carry moving load, improved aerator work-ing life effectively.
In the present invention, a pair of taper roller bearing 1.5 is keys of accepting with transmitted load, and its play is to regulate acorn nut 1.6 through bearing clearance to regulate, and makes it be in suitable working order.
