Abstract
The utility model relates to a main shaft structure of a pen making centrifuge, which comprises a main shaft and a bearing seat. The main shaft is inserted into the bearing seat, supported through a bearing, and sleeved by a shaft sleeve; an endless groove used for forming a labyrinth is formed in the periphery of the main shaft; a bulge is formed on the bearing seat; and a labyrinth sealing part is formed in a gap between the bulge and the endless groove. The main shaft structure adopts labyrinth sealing, does not have solid contact, is not required to be lubricated, allows thermal expansion, has good sealing effect, and is suitable for high-temperature, high-pressure and high rotation speed frequency occasions.
Description
Technical field
the utility model relates to a kind of main axle structure of a system centrifuge.
Background technology
The main axle structure of
centrifuge is the hinge that connects working cell and power unit; Main shaft is used to drive the rotary drum running; The effect of main shaft seal directly influences the service life of transmission and centrifuge, at present common O RunddichtringO sealing effectiveness and stable all compare poor.
Summary of the invention
The purpose of
the utility model provides a kind of main axle structure of a system centrifuge.
For achieving the above object, the technical scheme that the utility model adopts is:
