Heat energy is converted to the mechanical energy exported by diesel oil bent axle, but is not used to directly drive driving wheel, but is changed by transmission device
To be adapted to the mechanical energy of locomotive tractive characteristic requirement, then locomotive driving wheel is driven to rotate in orbit by EEF bogie.China from
Start within 1958 to manufacture diesel locomotive, successively there are 3 kinds of model locomotives such as easterly type to put into batch production earliest.Phase after 1969
After 15 kinds of new architectures of the grade of east wind 4 have been produced in batches, compared with first generation diesel locomotive, in power, structure, the diesel engine thermal efficiency
In gear efficiency, all it is significantly increased；But also resistive braking or hydraulic braking and hydraulic changeover, machine are additionally arranged respectively
Each system protection of car and fault diagnosis show, micro-processor controlled function；Employ integral body, hydrostatic drive etc. a series of
New technology；Locomotive reliability and service life aspect, performance improve a lot.
The ventilation blower of diesel locomotive is mainly reduction locomotive rectifier cabinet and synchronous main alternator and trailing or leading bogie traction electricity
The heat that motivation is produced, it is ensured that each motor normal work.Bearing must be changed during ventilation machine overhauling, impeller axle upper bearing (metal) is disassembled.
Traditional method for disassembling impeller axle bearing is mainly to be disassembled by hammering method, and this method has destructive, if
Certain damage can be caused when firmly larger to impeller axle, having can notably cause scrapping for impeller, cause unnecessary to enterprise
Financial burden.
The content of the invention
The utility model is in order to solve the above-mentioned technical problem, there is provided a kind of diesel locomotive bearing disassembles frock, its design
It is simple structure, scientific and reasonable, it is easy to use.Instead of the mode of traditional hammering dismounting bearing, it is to avoid impeller causes to damage, and
And manpower has been liberated, and improve and disassemble quality, improve production efficiency.
The technical scheme that the utility model is used is：A kind of diesel locomotive bearing disassembles frock, including underframe, side plate
And bearing baffle, frock bottom is provided with underframe, and underframe top both sides are provided with side plate, and side plate passes through to be welded and fixed with underframe, side

Plate is mutually welded with underframe, and bearing baffle is provided with semi-circular recesses, and backboard, backboard and bearing are provided with beside bearing baffle
The distance between baffle plate is 650mm, and backboard is welded on underframe, and bracing strut is welded with the outside of backboard.
The side plate, bearing baffle, backboard and bracing strut are section bar, and underframe is made up of angle steel.
The length over end sills is 1250mm.
The use process that this diesel locomotive bearing disassembles frock is：By the bracing strut of frock rear end and the part stretched
On the fixed mount of underframe insertion dismounting impeller machine, frock is fixed, the ventilation arbor with bearing is placed on the semicircle of frock
On connected in star, the shaft end of ventilation blower is pressed with the push rod of dismounting impeller machine, fan shaft stress is moved rearwards by, and bearing is by the axle of frock
Hold baffle plate to block, bearing just can come off from fan shaft, reach the purpose for disassembling bearing.
The frock bottom is provided with underframe, and underframe top both sides are provided with side plate, and side plate is with underframe by being welded and fixed；This
Sample set purpose be：Can be conducive to reinforcing frock, make frock firmly, improve the service life of frock.
Steel plate is set on the side plate, and steel plate welds together jointly with side plate, underframe；So set purpose be：Energy
It is enough fan shaft is supported during fan shaft is moved, keep fan shaft movement steady, be conducive to disassembling for bearing.
Described that underframe one end is provided with bearing baffle, bearing baffle is mutually welded with underframe front end；The purpose for so setting
It is：During fan shaft is moved, can effectively prevent bearing from moving, limit the axial displacement of bearing, reach
To the purpose for disassembling bearing.
The bearing baffle is provided with semi-circular recesses；So set purpose be：Fan shaft can be placed on bearing
On baffle plate, prevent from producing damage to fan shaft in moving process.
Described that backboard is provided with beside bearing baffle, the distance between backboard and bearing baffle are 650mm, backboard
It is welded on underframe, bracing strut is welded with the outside of backboard；So set purpose be：Frock can be carried out effectively solid
It is fixed, facilitate disassembling for bearing.
The beneficial effects of the utility model：What the technical program provided a kind of diesel locomotive bearing disassembles frock, its design
