Thickness of shell effectively reduces the electric machine structure in the small pump of motor manufacturing cost without influencing motor assembling.
The purpose of this utility model can be realized by following technical proposal：A kind of electric machine structure in small pump, should
Motor includes shell, is installed on the drive end bearing bracket and rear end cap at shell both ends, and housing cavity is provided with rotor component, the biography of motor
Extend outside shell from preceding end cap central moving axis one end, which is characterized in that offered for water pump vane on the transmission shaft
The keyway of installation, keyway is located on transmission shaft and drive end bearing bracket is equipped with the retaining ring of auxiliary seal, and the top of transmission shaft is tapped with
Screw thread circumferential direction and is evenly provided with the mounting bars of several integral structures on the outer wall of the shell, and the two of the mounting bar
It holds and offers screw hole, the outer ring of the drive end bearing bracket and rear end cap has position lug corresponding with mounting bar both ends and lug
Center offers the through-hole passed through for screw, and the both ends of the shell are respectively by hexagon socket head cap screw by drive end bearing bracket and rear end cap
It is fixed.
The technique effect of this electric machine structure is：The transmission shaft of motor is used to install water pump vane by keyway, and in end
Tightening nut fixes impeller at screw thread, wherein retaining ring act as auxiliary seal and mechanical seal together and prevent liquid into
Enter inside motor, relative to traditional electric machine structure, the utility model passes through the installation in shell outer ring setting integral structure
Item, and matched with the lug on front and rear cover, it is screwed with the screw hole on mounting bar by wearing hexagon socket head cap screw at lug
Cooperation makes front and rear cover be fixed on shell, and the design of the structure, which is equivalent to, makes the installation point of screw be detached with housing sidewall, can
For thickness effectively to reduce housing sidewall without influencing its installation, reducing the weight of shell reduces the Material Cost of enterprise.
In electric machine structure in a kind of above-mentioned small pump, the outer ring of the shell is uniformly disposed with several
The radiation tooth of integral type and bar-shaped trough for mounting bracket.The heat dissipation effect of shell can be increased by the design of radiation tooth,
Extend the service life of motor, bar-shaped trough act as mounting bracket and motor can be made to be fixed on pedestal by holder.
In electric machine structure in a kind of above-mentioned small pump, the rear end on the shell offers outlet hole.Pass through
Outlet hole makes to be connected inside electric wire and motor.
In electric machine structure in a kind of above-mentioned small pump, the axially extending shape in inside of the drive end bearing bracket and rear end cap
It is clearance fit between the limited step and inner walls at a circle limited step.Before being made by the setting of limited step
Being more firmly mounted for rear end cap, further prevents end cap to shift.
Compared with prior art, the electric machine structure in this small pump makes it have weight by being improved to electric machine casing
The advantages of measuring more fab-lite cost bottom.
