Abstract
The utility model relates to a flexible coupling, belonging to the filed of couplings. The flexible coupling is composed of a rigid connecting piece, a flexible force transmitting piece and an outer shell. The outer wall of the rigid connecting piece and the inner wall of the outer shell are both wave shaped. The rigid connecting piece is connected with a transmission shaft by a link. The flexible force transmitting piece is sheathed on the rigid connecting piece and the outer shell is sheathed on the flexible force transmitting piece. The outer shell is connected with the flange of another transmission shaft. Because the flexible coupling adopts the flexible force transmitting piece, when two transmission shafts are provided with different centers, the flexible force transmitting piece regulates the two transmission shafts to prevent normal running from being influenced.
Description
The utility model relates to shaft coupling, belongs to the coupling class in engineering unit, the parts.
In the treatment tank of oxidation ditch sewage treatment technology, usage level axle brush aeration machine.The kind of drive of this aerator is seen Fig. 1, and motor (1) drives aerator main shaft (3) by reducing gear (2), and aerator main shaft (3) connects with shaft coupling (4) with the output shaft of reducing gear (2).Aerator main shaft (3) two ends are installed on the bearing support (5), because aerator main shaft (3) length is longer, generally all have several meters long, thus when mounted two bearings will with the concentric installation of shaft coupling difficult (promptly concentric) with the output shaft of reducing gear.Rigid coupling and elastic coupling commonly used at present all can not meet the demands.So influence the normal operation of aerator.
The purpose of this utility model provides a kind of flexible connection that can transmit low rotation speed large torque.
Flexible connection of the present utility model is by rigid connector, and flexible force transmission spare and shell are formed.Rigid connector links to each other with transmission shaft with key, and flexible force transmission spare is enclosed within rigid connector outside and contact with it, adds the cover shell again in flexible force transmission spare outside.The outer wall of rigid connector and the inwall of shell are all made the waveform surface along circumference, and the crest of rigid connector is relative with the crest of shell during assembling.Because flexible force transmission spare squeezes in the centre of rigid connector and shell, and between the embedding crest, so the moment of torsion of output shaft can be passed on the shell, shell links to each other with flange on another transmission shaft, plays the effect of transmitting torque.
Illustrate that accompanying drawing is as follows:
Fig. 1 is a horizontal axis brush aeration machine schematic representation
Fig. 2 is the utility model flexible connection structural representation
Fig. 3 analyses and observe for the A-A of Fig. 2
Accompanying drawings embodiment is as follows:
Fig. 2 is the utility model flexible connection structural representation, and rigid connector (6) is sleeved on key on the output shaft (7) of reducing gear, and the flexible force transmission spare (8) that oil resistant rubber (tincture glue) is made is enclosed within the outside of rigid connector (6).Shell (7) is enclosed within the outside of flexible force transmission spare (8), and shell (9) connects with flange on another transmission shaft, and pressure ring (10) compresses flexible force transmission spare.Because between the crest between flexible force transmission spare (8) embedding rigid connector and the shell, so when main shaft (6) rotated, flexible force transmission spare (8) just can be passed to shell (9) to moment of torsion, thereby passes to another transmission shaft, plays the effect of transmitting torque.
The utility model has been owing to adopted flexible force transmission spare, so when the installation decentraction of two transmission shafts, can be adjusted unlikely influence normal operation by flexible force transmission spare.
