Detailed Description
In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and for a person skilled in the art, other drawings and other embodiments can be obtained without inventive effort, and the invention is not limited to this example.
Referring to fig. 1 to 3, an aluminum cast impeller shaft bushing according to an embodiment of the present invention includes an impeller shaft bushing main body 1, a shaft hole 3 is formed inside the impeller shaft bushing main body 1, the shaft hole 3 is communicated with a connection cavity 32, a connection structure 11 for connecting a clutch is disposed on an outer surface of the impeller shaft bushing main body 1, and a limit reinforcement member 2 is disposed at one end of the impeller shaft bushing main body 1.
As described above, the lining material of the impeller shaft is made of zinc-aluminum alloy, that is, the material of the main body 1 of the impeller shaft lining is made of zinc-aluminum alloy, and the connection structure 11 on the outer surface of the impeller shaft lining needs a certain hardness, and for the convenience of production and processing, zinc-aluminum alloy is preferably used; the connection cavity 32 is used for being connected with a motor driving shaft, the motor driving shaft drives the impeller shaft bushing, and the impeller shaft bushing drives the clutch through the connection structure 11 on the outer surface; wherein spacing reinforcement 2 is used for spacing with the hookup location of clutch, makes the impeller shaft bushing and motor drive shaft connection more firm simultaneously.
In this example, the connecting structure 11 is a rack arranged axially along the connecting cavity 32.
The above-mentioned rack may be formed by digging a groove in the pulsator bushing main body 1, or by welding a rack to the pulsator bushing housing, the rack being used for coupling with the clutch, so that a corresponding structure is also provided at a corresponding position of the clutch for coupling with the pulsator bushing, the shape of the structure being the same as the size of the groove between the racks, thereby enabling a tight sealing between the pulsator bushing and the clutch.
In this example, the thickness of the rack gradually increases from the outer end to the inner end.
The rack in the shape can enable the impeller shaft bushing and the clutch to be tightly combined, and simultaneously, the corresponding structures of the impeller shaft bushing and the clutch can be relatively easily connected.
In this example, the position limiting reinforcement 2 comprises a position limiting member 21 and a fastening member 22 which are connected.
In this embodiment, the limiting member 21 is an annular boss integrally disposed at one end of the shaft bushing body 1 for limiting the connection position of the shaft bushing.
The annular boss can abut against the clutch and block the impeller shaft bushing from continuing to advance when the non-annular boss part of the impeller shaft bushing is connected with the clutch, so that the impeller shaft bushing is limited.
In this example, the fastening member 22 is an annular table disposed at the outer end of the limiting member 21, and the outer ring of the fastening member 22 is provided with a thread.
The fastening member 22 is used for being connected with a corresponding structure of the motor driving shaft so as to stabilize the connection between the impeller shaft bushing and the clutch, therefore, a corresponding screw connection structure is arranged on the motor driving shaft, the screw connection structure is connected with the motor driving shaft through a rotary bearing so that the rotation of the driving shaft can not drive the screw connection structure to rotate, the screw connection structure is a cylindrical screw sleeve, a screw connection hole is arranged in the middle of the screw sleeve, the driving shaft passes through the screw connection hole and is connected with the screw sleeve through a bearing, the size of the screw connection hole is approximately the same as that of the fastening member 22, so that the screw connection structure is in screw connection with the fastening member 22 so that the driving shaft can be driven to advance along the direction of the impeller shaft bushing, meanwhile, after the screw connection is completed, the impeller shaft bushing can not move relative to the driving shaft, the abrasion problem and the possible fault problem caused by the untight connection can be avoided, and simultaneously, thereby avoiding the disadvantage that the traditional close-fit connection structure 11 needs to be assembled by a worker with great force.
In this embodiment, the limiting member 21 and the fastening member 22 are both provided with a through hole therebetween, and the through hole has the same diameter as and communicates with the shaft hole 3, so that the driving shaft can be inserted into the shaft hole 3 through the through hole.
In this embodiment, the diameter of the connection cavity 32 is larger than the diameter of the shaft hole 3, if the connection cavity 32 is smaller than the shaft hole 3, the motor driving shaft may not be inserted into the connection cavity 32, and the diameter of the connection cavity 32 needs to be larger than the shaft hole 3 because the connection structure 11 connected with the motor driving shaft needs to be arranged on the connection cavity 32.
In this embodiment, a strip-shaped groove 31 for connecting a driving shaft of a motor is formed in the connecting cavity 32 of the shaft hole 3 and located on the inner wall of the impeller shaft bushing, and the extending direction of the strip-shaped groove 31 is along the axial direction of the impeller shaft bushing.
In this example, the number of the strip-shaped grooves 31 is 5 to 15.
Specific embodiments of the present invention have been described above in detail. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by logical analysis, reasoning or limited experiments in the prior art, which are already known to those skilled in the art, should be within the scope of protection defined by the claims.
