Description
Technical field
The utility model is related to machinery manufacturing technology field more particularly to a kind of bearing spindle structures.
Background technology
Hydrostatic spindle design process and assemble is all extremely difficult at present, before static pressure is not established, if rotation main shaft or dismounting
Related part, main shaft are possible to direct friction with bearing and damage on main shaft, the type spindle mounted, working service, repair
It is all cumbersome, it is larger to promote the use of difficulty.
Invention content
Motive spindle or dismounting before not established purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of static pressure
Correlated parts and be not damage main shaft, bearing bearing spindle structure.
What the purpose of this utility model was realized in：
A kind of bearing spindle structure, including main shaft and mounting base；The sliding bearing is set in mounting base, the sliding
It is equipped with main shaft in bearing, rolling bearing, the step surface and sliding bearing of the main shaft are provided between the main shaft and mounting base
End face between be provided with adjustment partition, the both ends of the mounting base are provided with seal cover board.
A kind of bearing spindle structure, is provided with adjustment partition between the step surface of the main shaft and the end face of rolling bearing.
A kind of bearing spindle structure is sealed or is combined close with labyrinth seal or sealing ring between the main shaft and seal cover board
Envelope.
A kind of bearing spindle structure, the main shaft outer circle and sliding bearing are without being in direct contact.
Compared with prior art, the utility model has the beneficial effects that：
The utility model is simple in structure, of low cost, installation, easy to maintain, and reliability is high, can anti-misoperation lead to structure
It is impaired.When especially static pressure does not have motive spindle before foundation or dismantles correlated parts, it is not damage main shaft, bearing.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Wherein：
Main shaft 1,
Seal cover board 2,
Sliding bearing 3,
Mounting base 4,
Rolling bearing 5,
Adjust partition 6.
Specific implementation mode
Referring to Fig. 1 the utility model is related to a kind of bearing spindle structure, including main shaft 1 and mounting base 4.
The sliding bearing（3）It is set to mounting base（4）It is interior, the sliding bearing（3）It is interior to be equipped with main shaft（1）, the master
Axis（1）Outer circle and sliding bearing（3）Without being in direct contact when work, the main shaft（1）With mounting base（4）Between be provided with the axis of rolling
It holds（5）.The main shaft（1）Step surface and sliding bearing（3）End face between be provided with adjustment partition, the main shaft（1）'s
Step surface and rolling bearing（5）End face between be also equipped with adjustment partition（6）.The mounting base（4）Both ends be provided with
Seal cover board（2）, the main shaft（1）With seal cover board（2）Between with labyrinth seal or sealing ring sealing or combination sealing.
Operation principle：
When the utility model main shaft 1 works, radially, axially sliding bearing 3 is leaned on to support, 5, rolling bearing is leaned on when inoperative
It holds, main shaft 1 and sliding bearing 3 are without being in direct contact.
The utility model rolling bearing 5 is radial and axially has the floating of certain size, amount of floating to be less than main shaft 1 and sliding axle
The actual gap between 3 is held, when sliding bearing 3 works, rolling bearing 5 does not influence the radial centering and axially position of main shaft 1.
The utility model main shaft 1 and the axial gap of sliding bearing 3 ensure by the thickness of unilateral or both sides adjustment partition.
The specific application example that the above is only the utility model does not constitute the scope of protection of the utility model any limit
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
