Description
Technical field
The invention belongs to nuclear power station rotating machinery maintenance engineering technical fields, and in particular to a kind of rolling bearing disassembly is general
Tool.
Background technique
Rolling bearing is support rotating equipment rotor part, and keep rotor normal operation position and running accuracy one
Kind of precision mechanical components, in the industrial production with relatively broad, in field gulf nuclear power station, most of rotating machinery is also applied to
Rolling bearing.Nuclear power station first stage of the project 2 units in field gulf are configured with more than 400 altogether, various types of pumps are provide for unit can
By " power ", rolling bearing damage will lead to pump group vibration and become larger, influences the normal operation of pump group.To guarantee its normal operation,
It need to periodically be overhauled, replace roller bearing component.Since rolling bearing and pump shaft are interference fit, when disassembly, needs by outer
Power could be removed.The drawing horse used when the small-sized rolling bearing of daily disassembly is difficult to level, and is easy to bear the axis of rolling partially, deposit
In stuck risk, pump shaft is caused to damage；Rolling bearing inner ring is slightly larger compared with the shaft shoulder, draws horse handgrip and rolling bearing inner ring contact area
It is too small, exist and collapse de- risk, causes maintenance personal injured；When rolling bearing is dismantled, pump shaft is not allowed to be fixed easily, and someone's helping is needed to pump
Axis increases disassembly difficulty；Pump shaft is different with the model of rolling bearing, and the selection of extracting tool is also cumbersome, causes entirely to tie up
It is time-consuming and laborious to repair work, inefficiency.
When disassembly and the relatively large rolling bearing of axle sleeve interference fit, end face of shaft bush is carried out using vertical electric hydraulic bed
Squeeze, until axle sleeve and bearing inner race are detached to realize disassembly, but the axial force that hydraulic bed applies can not manually control, exist compared with
Big security risk, and be easy that axle sleeve is caused to damage；When disassembly and the rolling bearing of axle journal interference fit, if axle journal position is arrived
The distance of axial end is too long, then conventional tool is difficult to be dismantled, and is easy to cause to damage to axis；It is separable to dismantle Internal and external cycle
When rolling bearing, rolling bearing inner ring and axle sleeve or axle journal are interference fitted, and conventional tool is difficult to be dismantled, and are easy to axle sleeve
Or axis causes to damage.
Rolling bearing extracting tool of the invention can reach the preferable depth of parallelism by adjusting four screw rods, can be to avoid handle
The axis of rolling is born to be caused stuck with pump shaft partially, is injured caused by pump shaft；There are two semicircle solid for the rolling bearing extracting tool
Price fixing can preferably fix rolling bearing, can also be adapted to the rolling of different model by adjusting the distance of two fixed disks
Bearing；The different rolling of the distance that the rolling bearing extracting tool can be adapted to axle journal position to axial end by regulation handle
Bearing；The rolling bearing extracting tool uses fluid pressure drive device, keeps rolling bearing disassembly process more laborsaving, improves maintenance effect
Rate.
How roller bearing component is reliably fixed and is dismantled, in maintenance process personnel and equipment pacify
Entirely, it is of great significance.
Summary of the invention
Present invention solves the technical problem that:
The present invention provides a kind of rolling bearing disassembly general utility tool, and structure is simple, easy to use, can tear open in rolling bearing
It realizes and is reliably fixed during unloading, effectively evade the potential risk for threatening personnel and equipment safety in maintenance process, effectively solve
The disassembly problem of Jue Liao power plant different model rolling bearing.
The technical solution adopted by the present invention:
A kind of rolling bearing disassembly general utility tool, including fixed plate, screw rod, hydraulic device, handle, lead screw, top, bearing
Sleeve, bearing, square chest, shifting chute, fixed disk.
The fixed disk is mounted on square chest, and shifting chute is provided on square chest.
The fixed disk can move along slot and be adjusted.
The bearing sleeve and bearing are placed in fixed disk jointly.
The fixed plate is connect by screw rod with square chest；The middle position of fixed plate is provided with through-hole, and lead screw passes through through-hole.
The top of the lead screw is equipped with handle and hydraulic device, and bottom end is equipped with top.
The top is located above bearing sleeve to just contacting.
Start hydraulic device, top reaches pressure at bearing sleeve, is finally reached the purpose of disassembly.
Beneficial effects of the present invention:
(1) a kind of rolling bearing of the invention disassembly general utility tool is simple and reliable for structure, easy to operate；
(2) a kind of rolling bearing of the invention disassembly general utility tool can efficiently solve electricity according to the adjusting of bearing size
The disassembly problem of factory's different model bearing；
(3) a kind of rolling bearing of the invention disassembly general utility tool can be adjusted according to the length of pump shaft, improve the work
The applicability of tool；
(4) a kind of rolling bearing of the invention disassembly general utility tool fixed disk contacts closely with rolling bearing, effectively solves
Rolling bearing disassembly process middle (center) bearing inner ring and common horse handgrip is drawn to collapse de- problem；
(5) a kind of rolling bearing of the invention disassembly general utility tool rolling bearing is fixed, efficiently solves common drawing
The problem of external force causes pump shaft rotation to need helping when horse dismantles rolling bearing；
(6) a kind of rolling bearing of the invention disassembly general utility tool can be adapted to axle journal position to axis by regulation handle
The different rolling bearing of the distance of end face；
(7) a kind of rolling bearing of the invention disassembly general utility tool uses fluid pressure drive device, dismantles rolling bearing
Journey is more laborsaving.
