The utility model provides a be used for centrifugal compressor impeller locking device, central shaft hole connect a set of jack around the circumference, the jack be located the major diameter one side of impeller, the pivot open around the circumference have a pair of jack, the jack with to the jack relative setting, quantity equal, to jack connection spring, spring coupling circle inserted bar, circle inserted bar pop out and insert the jack internal fixation.
The impeller locking device for the centrifugal compressor is characterized in that the middle of the 8-shaped upper fixing piece is bent, the middle of the 8-shaped lower fixing piece is bent, and caps of screws are respectively embedded into the top and the bottom of the right semicircular buckling plate.
Has the advantages that:
1. the impeller is fixed through triple locking, so that the tightness and firmness of connection between the impeller and the rotating shaft are ensured, the synchronous operation between the impeller and the rotating shaft is ensured, and the locking effect is good.
2. According to the invention, the left insert rod is inserted into the left positioning hole, and the right insert rod is inserted into the right positioning hole to perform a double locking and fixing on the connection between the impeller and the rotating shaft, so that the impeller and the rotating shaft are firmly connected.
3. The left semicircular buckle plate and the right semicircular buckle plate are clamped into the annular groove to be locked and fixed in a double mode, 8-shaped upper fixing pieces and 8-shaped lower fixing pieces are used for further fixing, the left semicircular buckle plate and the right semicircular buckle plate are firmly assembled with the annular groove, and the fixed impeller is firmly connected with the rotating shaft.
4. The circular inserted bar is popped out and inserted into the jack to carry out triple locking and fixing, so that the head end and the tail end of the connection between the impeller and the rotating shaft are simultaneously locked and fixed, the locking is firm, and the locking effect is good.
Description of the drawings:
fig. 1 is a schematic structural diagram of the product.
Fig. 2 is a rear view of fig. 1.
The specific implementation mode is as follows:
the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.
Example 1:
a locking device for centrifugal compressor impeller comprises an impeller 1, wherein the impeller is provided with a central shaft hole 2, the central shaft hole is connected with a rotating shaft 3, the front end of the rotating shaft is provided with an annular groove 4, the annular groove is pressed close to one side of the small diameter of the impeller, the annular groove is connected with a left positioning hole 5 and a right positioning hole 6, the annular groove is clamped into a left semicircular buckle plate 7 and a right semicircular buckle plate 8, the left semicircular buckle plate is connected with a left plunger 9, the left plunger is inserted into the left positioning hole for positioning and fixing, the rotating shaft can be fixed and connected with the left semicircular buckle plate, the impeller is fixed, the right semicircular buckle plate is connected with a right plunger 10, the right plunger is inserted into the right positioning hole for positioning and fixing, the rotating shaft can be fixed and connected with a right semicircular buckle plate, the impeller is fixed, the left semicircular buckle plate is riveted with one side of an 8-shaped upper 11, the 8-shaped upper fixing piece is fixed with the top of the right semicircular buckle plate through a screw 12, the left semicircular buckle plate is riveted with one side of the 8-shaped lower fixing piece 13, and the other side of the 8-shaped lower fixing piece is fixed with the bottom of the right semicircular buckle plate through a screw.
