Description
Technical field
The invention belongs to engine maintenance technical field, and in particular to a kind of use for diesel engine crank spindle watt extracting tool and
Method for dismounting.
Background technology
For crank spindle watt as crankshaft of diesel engine and the important connection member of body, it subjects the high-speed rotation of bent axle with squeezing
Pressure, diesel engine test run terminate or diesel engine longtime running after, it is necessary to open and inspect the postrun state of main bearing shell, it is commonplace
After method is exactly machine end of run, after body main beating cap is disassembled, the main bearing shell situation with the base bearing contact is checked,
If it is desired to check the main bearing shell contacted with body, it is necessary to bent axle is disassembled the feelings for checking the main bearing shell being connected with body
Condition, the method workload is big, takes time and effort.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of use for diesel engine crank spindle watt extracting tool
And method for dismounting.
The present invention adopts the following technical scheme that to complete above-mentioned purpose：
A kind of use for diesel engine crank spindle watt extracting tool, described extracting tool have volume watt main body；Described volume watt main body
For the arc-shaped on fitting main bearing journal, the both ends of the volume watt main body have rectangle neck, and the rectangle neck respectively
Width of rebate be more than main bearing shell width；Be provided with the aperture surface of the volume watt main body to the oil on main bearing journal
The wedge axle that road kiss is matched somebody with somebody；Described wedge axle is provided with O-shaped groove, is easy to install O-ring additional, and wedge shaft end has chamfering, is easy to load bent axle
In trunnion oil hole；There is screwed hole in the outer diameter face of the volume watt main body；Described extracting tool also includes and volume watt
The handle of screwed hole threaded connection in main body；The bottom of the handle has external screw thread, is easy to and volume watt outside sweep
Screwed hole connects；The upper end of the handle has o-ring.
The method dismantled using a kind of above-mentioned use for diesel engine crank spindle watt extracting tool is：First by main beating cap
Dismantle；Then the volume watt wedge axle equipped with O-ring is inserted in the oil duct of main bearing journal, then jiggering, makes main bearing shell insertion volume
In watt rectangular aperture, continue jiggering, drive volume watt to move by bent axle and then drive main bearing shell motion, when main bearing shell is completely from body
After position comes out, you can check the situation of trunnion bearing shell, after checking, bent axle, is gone to initial disk parking stall by jiggering again
Put, volume watt can also produce, and in the screw thread the outside sweep middle part for being threaded into volume watt of O-shaped handle, can draw O-shaped handle
O-ring, volume watt is pulled up；Finally main bearing shell is put on main bearing journal, it is original to slide into body with hand handle main bearing shell
Corresponding position.
A kind of use for diesel engine crank spindle watt extracting tool of the present invention and method for dismounting, the tool construction is simple, user
Just, cost is low, can open and inspect main bearing shell in the case where not dismantling bent axle, greatly reduces worker and checks main bearing journal axle
Watt labor intensity and working time, improve operating efficiency.

Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, and combine Fig. 5, a kind of use for diesel engine crank spindle watt extracting tool, described extracting tool has
Roll up watt main body 1；With reference to Fig. 2, Fig. 3, described volume watt master, 1 arc-shaped to be bonded on main bearing journal, the volume watt main body 1
Both ends there is rectangle neck 11 respectively, and the width of rebate of the rectangle neck 11 is more than the width of main bearing shell 5；The volume watt
The wedge axle 12 to match somebody with somebody with the oil duct kiss on main bearing journal is provided with the aperture surface of main body 1；Described wedge axle 12 is provided with O
Type groove 13, it is easy to install O-ring additional, wedge shaft end has chamfering 14, is easy to load in main bearing journal oil hole；The volume watt main body
Outer diameter face on there is screwed hole 15；Described extracting tool also includes to be threadedly coupled with the screwed hole in volume watt main body
