SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that the stator is difficult to extract from the motor casing after long-time use of traditional motor.
In order to achieve the purpose, the utility model discloses a basic scheme provides a motor stator fixing device, including motor casing and a plurality of stator installation piece of establishing in the motor casing, the locking spout has all been opened to the one end of stator installation piece, the equal rigid coupling of the other end of stator installation piece has the link block that can insert the locking spout, a plurality of stator installation pieces connect gradually through locking spout and link block end to end and form an annular stator mount pad, a plurality of locating holes have all been opened to stator installation piece side, all be equipped with a plurality of location bolts that can insert the locating hole on the motor casing.
The principle and effect of this basic scheme lie in:
1. the stator mounting blocks are connected with the connecting sliding blocks through the locking sliding grooves to form an annular stator mounting seat, and the connecting sliding blocks are inserted into the locking sliding grooves in the axial direction of the annular space, so that the whole annular mounting seat cannot be loosened due to radial extrusion of the stator in the mounting seat.
2. Then the stator is in interference fit in the annular stator mounting seat, so that the stator can be fixedly mounted in the annular mounting seat formed by the stator mounting blocks, and the basic structure of the stator cannot be damaged.
3. The annular mounting base provided with the stator is arranged in the motor shell, and the positioning bolt on the motor shell is inserted into the positioning hole of the stator mounting block, so that the stator is arranged in the motor shell.
4. If need clean in the motor casing after long-time the use, perhaps the motor breaks down and needs to maintain it, just this moment just available bottle opener will fix a position the bolt and extract from the locating hole in, then open the motor casing, directly take out whole stator and stator installation piece, take out the stator installation piece of interconnect in proper order by the axial, alright peel off the stator and go on keeping a public place clean or maintenance work.
Compared with the prior art, this motor stator fixing device not only can effectually fix the stator, has simplified the installation and the dismantlement work of stator moreover, and the simple operation, labour saving and time saving is more stable during the use, is convenient for promote on a large scale.
Further, stator installation piece bilateral symmetry is equipped with solid fixed ring. The stator mounting block can be prevented from slight axial displacement by the fixing ring.
Furthermore, stator installation piece both sides all are equipped with first screw hole, and the last threaded connection of solid fixed ring has a plurality of first set screws that can twist into first screw hole. Through first screw hole and first locking screw mutually support, can effectually install solid fixed ring in the both sides of stator installation piece.
Furthermore, the side edge of the fixing ring is provided with a plurality of second threaded holes, and the motor shell is in threaded connection with a plurality of second locking screws capable of being screwed into the second threaded holes. Through second screw hole and second locking screw mutually support, can effectually install solid fixed ring in the motor casing, improve operating stability.
Further, the upper wall of the stator mounting block is coated with an antirust oil film. The antirust oil film prevents the stator mounting block from rusting in the using process.
Further, a buffer gasket is arranged between the stator mounting block and the inner wall of the motor shell. The buffer gasket can reduce the vibration of the motor in the operation process.
Furthermore, the positioning bolt is in interference fit with the positioning hole. The stator mounting block is convenient to fix in the motor casing, and the stability of long-time operation of the motor is improved.
