Abstract
The utility model discloses a power mechanism of a large flip-type centrifugal machine. The power mechanism comprises a main shaft and a rotary drum. The main shaft is arranged on a bearing pedestal through bearings, the other end of the main shaft is fixedly connected with the rotary drum, an oil seal is arranged between the main shaft and the bearing pedestal, the main shaft is sleeved with a shaft sleeve, one end of the shaft sleeve is fixedly connected with the rotary drum, and the other end of the shaft sleeve is located between the bearing pedestal and the main shaft. According to the power mechanism, the main shaft is sleeved with the shaft sleeve located between the bearing pedestal and the rotary drum, pollutants entering the main shaft are effectively reduced due to the shaft sleeve, therefore, damage to the main shaft is alleviated, and the service life of the main shaft is prolonged.
Description
Technical field
The utility model relates to a kind of centrifuge, particularly a kind of large flip-shell centrifuge actuating unit.
Background technology
Between traditional centrifuge principal axis and bearing block, exist an intersegmental gap to guarantee the smooth rotation of rotary drum, but, because this intersegmental gap outside does not have safeguard measure, can produce pollution for a long time, thereby cause spindle abrasion and shorten service life of centrifuge.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of large flip-shell centrifuge actuating unit, to extend the service life of main shaft.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of large flip-shell centrifuge actuating unit, comprise main shaft and rotary drum, described main shaft is arranged on bearing block by bearing, the other end of described main shaft is fixedly connected with described rotary drum, be provided with oil sealing between described main shaft and bearing block, also be arranged with axle sleeve on described main shaft, an end of described axle sleeve is fixedly connected with described rotary drum, and the other end of described axle sleeve is between described bearing block and main shaft.
Preferably, an end of described axle sleeve is bolted on described rotary drum.
Preferably, the other end of described axle sleeve is between the oil sealing and described main shaft of described bearing block.
Pass through technique scheme, the large flip-shell centrifuge actuating unit that the utility model provides, it is set in the axle sleeve between bearing block and rotary drum by cover on main shaft, and the use of axle sleeve has effectively reduced pollutant and has entered main shaft, thereby delay the main shaft breakage, extended the service life of main shaft.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, in below describing embodiment, the accompanying drawing of required use is briefly described.
Fig. 1 is the disclosed large flip-shell centrifuge actuating unit partial structurtes schematic diagram of embodiment.
Numeral in figure:
11. bearing block 12. main shaft 13. rotary drums
14. oil sealing 15. axle sleeve 16. bolts
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 1, the large flip-shell centrifuge actuating unit that the utility model provides, comprise main shaft 12 and rotary drum 13, main shaft 12 is arranged on bearing block 11 by bearing, the other end of main shaft 12 is fixedly connected with rotary drum 13, between main shaft 12 and bearing block 11, is provided with oil sealing 14, also is arranged with axle sleeve 15 on main shaft 12, one end of axle sleeve 15 is fixed on rotary drum 13 by bolt 16, and the other end of axle sleeve 15 is between the oil sealing 14 and main shaft 12 of bearing block 11.
The large flip-shell centrifuge actuating unit that the utility model provides, it is set in the axle sleeve 15 between bearing block 11 and rotary drum 13 by cover on main shaft 12, the use of axle sleeve 15 has effectively reduced pollutant and has entered main shaft 12 by the gap between rotary drum 13 and bearing block 11, thereby delay main shaft 12 breakages, extended the service life of main shaft 12.
Multiple modification to above-described embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.
