Description
Technical Field
The invention relates to the technical field of end face damage repair, in particular to a device for repairing gear end face damage on a gear pump.
Background
Military aircraft radar cooling system's power supply is the gear pump, and the gear pump is the displacement pump, structural characteristics that just leak the height to one side in just having, and after using a cycle, the condition such as part wearing and tearing crushing is many, and the gear is higher at the rotational speed in the work, and impurity in the coolant liquid can damage gear and copper bush complex surface when high-speed rotation, leaves annular work vestige at the gear terminal surface, influences the end face seal effect. The gear is the essential element of gear pump, and the gear rotates at a high speed at 4600r/min during operation, and its upper and lower terminal surface is the sealed face, and surface quality requires higher, and current gear repair means is very limited, is difficult to resume the original work efficiency of pump. The methods of polishing gear shaft necks, improving surface states through vibration finishing and the like can only improve the running stability of the pump and cannot reduce the leakage of cooling liquid from the end faces of the gears.
Disclosure of Invention
In order to solve the technical problem, the invention provides a device for repairing the damage of the end face of a gear on a gear pump.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
a device for repairing damage to a gear face on a gear pump, comprising:
the central axis of the adjusting cap and the sleeve is provided with a through hole, a closed cavity for placing the gear is formed by the upper part and the lower part, and the closed cavity can be adjusted by changing the relative distance between the adjusting cap and the sleeve;
the grinding block is arranged in the adjusting cap and the sleeve and does not rotate relative to the adjusting cap and the sleeve;
and the spring is arranged between the grinding block and the adjusting cap and between the grinding block and the adjusting sleeve and is used for adjusting the pre-tightening force of the grinding block.
Preferably, the adjusting cap and the sleeve are connected through threads.
Preferably, the inside of adjusting the block is equipped with the draw-in groove one that is used for placing the abrasive brick.
Preferably, the inside of sleeve is equipped with the draw-in groove two that is used for placing the abrasive brick.

Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.
As shown in fig. 1 to 4, a gear end face damage repairing device on a gear pump is composed of an adjusting cap 1, a grinding block 2, a sleeve 3 and a spring 4. The adjustable nut cap is characterized in that an internal thread is arranged on the adjustable nut cap 1, an external thread is arranged on the sleeve 3, the adjustable nut cap 1 and the sleeve 3 are connected through the thread to form a closed cavity, and the volume of the closed cavity can be adjusted by changing the relative position of the adjustable nut cap 1 and the sleeve 3. The central axis of the adjusting cap 1 and the central axis of the sleeve 3 are both provided with through holes, and the size of the through holes is matched with the diameter of the gear shaft. The adjusting cap 1 and the sleeve 3 are correspondingly provided with a first clamping groove and a second clamping groove.
Grinding block 2 and spring 4 all are equipped with two, and the symmetry side on two grinding block 2 all is the paralleling structure, and two grinding block 2 install in draw-in groove one and draw-in groove two after, do not take place relative rotation with regulation block 1. Two springs 4 set up between two grinding piece 2 and regulation block 1, sleeve 3, when changing the screw thread position of adjusting block 1, sleeve 3, can adjust the compression of spring 4 to change the pretightning force of grinding piece 2 on the gear terminal surface.
The invention can provide the initial pressure of end face grinding by internally arranging the bidirectional clamping spring 4, and can adjust the grinding clamping force by adjusting the cap 1.
The use process of the invention is as follows:
when the adjustable grinding device is used, a gear with a gear shaft is placed in the sleeve 3, the adjusting cap 1 is installed on the sleeve 3 in a threaded mode, after installation, the upper gear shaft and the lower gear shaft of the gear respectively penetrate through holes of the adjusting cap 1 and the sleeve 3, at the moment, the upper grinding block 2 and the lower grinding block 2 are abutted to the upper end face and the lower end face of the gear, the compression amount of the spring 4 is adjusted by rotating the adjusting cap 1, and the pre-tightening force of the grinding block 2 is adjusted; and then, a rotating force is applied to the gear shaft externally to enable the gear to rotate in the grinding device, and the gear and the grinding block 2 move relatively in the rotating process so as to achieve the effect of repairing the end face of the gear.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
