Technical Field
The invention relates to the field of mechanical design, in particular to a special tool for disassembling an elastic coupling.
Background
Flange plates of a GK1M type locomotive starter generator, an east wind 10D starter generator and an excitation motor are all connected by elastic couplings. Due to the characteristics of shunting operation, the locomotive is frequently started, and the elastic coupling rubber sleeve is easy to age and become brittle. According to statistics, the rubber sleeve is worn to the limit after being used for half a year to one year and needs to be replaced.
The metal pin in the middle of the elastic coupling is in a conical surface pin shape, and the operation space is narrow, so that the column body cannot be taken out. The parts such as a locomotive big cover, a protective cover and the like can only be removed firstly during each replacement, then the motor base screw is loosened, the coupling is separated by moving the motor, and the connecting pin is taken out. Not only wastes time and energy, prolongs the garage stop time to when installing again, the concentricity is difficult to adjust, and the maintenance quality is difficult to grasp.
Disclosure of Invention
The invention aims to provide a special tool for disassembling an elastic coupling so as to shorten the maintenance time and improve the maintenance quality.
In order to achieve the purpose, the invention adopts the following technical scheme:
a special tool for disassembling an elastic coupling comprises an upper arc plate, a left side plate vertically connected to the left lower part of the upper arc plate, and a right side plate vertically connected to the right lower part of the upper arc plate;
the lower surface of the upper arc plate is of an arc-shaped configuration for embedding the outer circle of the flange, and the left side of the lower surface of the upper arc plate is also provided with a limiting protrusion extending downwards;
a horizontal elastic coupling penetrating port is formed in the center of the left side plate;
a threaded hole is formed in the center of the right side plate, a pointed screw is screwed in from right to left, and a pointed end of the pointed screw is positioned at the left end and is positioned in the outer space on the left side of the threaded hole; the right end of the pointed screw is positioned in the outer space on the right side of the threaded hole and is fixedly provided with a rotating handle;
the central axis of the pointed screw and the central axis of the elastic coupling penetrating opening are positioned on the same horizontal straight line.
The left side tip of the pointed screw is in a conical configuration.
The weight of the left side plate is equal to the sum of the weight of the right side plate and the weight of the pointed screw.
Optionally, the outer circle of the rotating handle is provided with a relief protrusion for increasing friction force.
Optionally, the twist grip comprises a long rod attached vertically to the right end of the pointed screw.
The elastic coupling penetrating port is a round port.
Compared with the prior art, the invention has the advantages that no special tool is used in the past, the parts such as a locomotive large cover, a protective cover and the like need to be firstly removed when the elastic coupling is disassembled, then the motor base screw is loosened, the coupling is separated by moving the motor, and the connecting pin is taken out, so that the time and labor are wasted, and the maintenance quality is difficult to control. The elastic coupling disassembling special tool which is newly designed and manufactured overcomes the difficulties that the operation space is narrow and the pin is difficult to take out, and the like, and can take out the pin of the elastic coupling without moving the main generator, and the work of replacing a rubber sleeve and the like is completed.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the special tool for disassembling an elastic coupling of the present invention comprises an upper arc plate 4, a left side plate 12 vertically connected to the left lower part of the upper arc plate 4, and a right side plate 13 vertically connected to the right lower part of the upper arc plate 4;
the lower surface of the upper arc plate 4 is of an arc-shaped configuration for embedding the outer circle of the flange, and the left side of the lower surface of the upper arc plate 4 is also provided with a limiting protrusion 11 extending downwards;
a horizontal elastic coupling penetrating port 5 is formed in the center of the left side plate 12;
a threaded hole is formed in the center of the right side plate 13, a pointed screw 6 is screwed in from right to left, and the pointed end of the pointed screw 6 is positioned at the left end and is positioned in the outer space on the left side of the threaded hole; the right end of the pointed screw 6 is positioned in the outer space on the right side of the threaded hole and is fixed with a rotating handle 1;
the central axis of the pointed screw 6 and the central axis of the elastic coupling penetrating port 5 are positioned on the same horizontal straight line.
The left-hand point of the pointed screw 6 is of conical configuration.
The weight of the left side plate 12 is equal to the sum of the weight of the right side plate 13 and the weight of the pointed screw 6, so that the operation is stable.
