Description
Technical field
The utility model relates to aquaculture increases water oxygen technical field, relates in particular to the deceleration device that a kind of aerator is used.
Background technology
Aerator is mainly used in culture fishery, also is used for industrial sewage and handles, and traditional oxygenation way has ventilation oxygenation, vane type oxygenation and pump to spray three kinds of oxygenation, compare with other two kinds, the vane type oxygenation effect is good, and is simple in structure, is present most widely used oxygenation way.
Impeller automatic aerator mainly is made up of motor, reducing gear, impeller, support etc.Wherein reducing gear is to playing an important role in the performance and the service life of aerator, and in order to reach the required rotating speed of impeller, the motor via reducer structure reduces rotating speed.General reducing gear all adopts secondary or the above gear drive of secondary to realize slowing down.The shortcoming of this reducing gear is that axle is many, gear is many, shell shape is complicated, structure is not compact, the complete machine size is big, and in transmission process, because of change direction and rotating speed with multi-stage gear, energy loss is bigger, influences transmission, has reduced efficient.
The utility model content
The purpose of this utility model is in order to overcome above-mentioned prior art deficiency, a kind of speed changing structure compactness to be provided, high efficiency, the deceleration device that a kind of aerator that energy consumption is low is used.
The technical scheme that realizes the utility model purpose is: a kind of aerator deceleration device, have support, base, power shaft, output shaft and external axle, power shaft is arranged in the support, be connected with output shaft by reducing gear, external axle is arranged in the base, which is provided with external axial cone tooth, output shaft is provided with output axial cone tooth, external axial cone tooth and the engagement of output axial cone tooth; Described reducing gear have be arranged on power shaft) on eccentric bushing, eccentric bushing is provided with eccentric bushing bearing, eccentric bushing bearing is provided with cycloid gear, is arranged with two delivery outlets on the cycloid gear; Be provided with pin wheel housing in the support, pin wheel housing is provided with one group and is centered around the outer gear pin of cycloid gear, the local engagement of gear pin and cycloid gear; Described output shaft rotates by bearing and is arranged on the support, and fixedly connected pin frame on the output shaft is arranged with two pins on the pin frame, and two pins are arranged in the delivery outlet of above-mentioned cycloid gear, and the diameter of pin is less than the delivery outlet internal diameter of cycloid gear.
Above-mentioned aerator is two eccentric bushings of dislocation 180 degree with the eccentric bushing of deceleration device, and eccentric bushing is provided with two eccentric bushing bearings, respectively is provided with a cycloid gear on each eccentric bushing bearing, and described pin is arranged in the delivery outlet of two cycloid gears simultaneously.
All be with roller on two pins of above-mentioned aerator with deceleration device.
The above-mentioned aerator power shaft and the coaxial setting of output shaft of deceleration device.
Above-mentioned aerator is the conical gear that the identical modulus and the identical number of teeth are arranged with the external axial cone tooth of deceleration device with output axial cone tooth.
The utlity model has following characteristics: (1) the utility model adopts cycloid gear to slow down, when the power shaft band the eccentric bushing rotation, since on the Cycloidal Wheel characteristics of tooth curve and be subjected to the gear pin restriction so, the motion of Cycloidal Wheel becomes the plane motion that existing revolution has rotation again, when power shaft just circles, eccentric bushing also rotates a week, thereby Cycloidal Wheel turns over a tooth in rightabout and obtains slowing down, by pin the low speed spinning motion of Cycloidal Wheel is passed to the output shaft that is connected with the pin frame again, thereby obtain lower output speed, speed reducing ratio is bigger; When (2) the utility model adopts two eccentric bushings, double cycloid gear, the gears engaged number of teeth is more, overlap coefficient is big, and two eccentric bushings adopt the symmetry of dislocation 180 degree eccentric, make deceleration transmission have the mechanism of parts balance, and vibration and throat sound are limited in minimum degree; When (3) being with roller on two pins of the present utility model, effectively reduce friction, made transmission efficiency further improve; (4) the utility model power shaft and the coaxial setting of output shaft, the compact conformation volume is little.
