Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a special tool for torque of a generator drive gear coupler. Background Art

[0002] The generator drive gear coupler is a key component in the generator set. It is mainly used to connect the generator shaft and the drive gear to ensure the effective transmission of mechanical energy and play a protective role to a certain extent. The generator drive gear coupler can be divided into many types according to its structure and material, such as elastic coupler, fin coupler, star coupler, tooth coupler, etc. For example, the tooth coupler realizes the torque transmission between two rotating systems with different but adjacent axes through its unique gear meshing principle and structural characteristics.

[0003] The generator drive gear coupler torque tool currently used in my country has only four force-bearing teeth, and the teeth are not completely tight fit. When rotating, the four teeth cannot be stressed at the same time, which can easily cause the tool teeth to break or the gear coupler teeth to be damaged. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model discloses a special torque tool for a generator drive gear coupler. The technical solution adopted is that it includes a 3 / 8 short socket head, a connecting processing piece and a sleeve tooth. One end of the 3 / 8 short socket head is welded to one end of the connecting processing piece. A sleeve tooth is provided on the inner wall of the end of the 3 / 8 short socket head away from the connecting processing piece, and an anti-rust layer is provided on the 3 / 8 short socket head.

[0005] As a preferred technical solution of the present invention, the anti-rust layer is an oxide film formed by bluing the surface of the 3 / 8 short socket head.

[0006] As a preferred technical solution of the present invention, the 3 / 8 short socket head is made of No. 1 steel.

[0007] As a preferred technical solution of the present invention, the connecting workpiece is made of No. 1 steel, and the inner wall is formed into a sleeve tooth by turning and cutting.

[0008] As a preferred technical solution of the present invention, a plurality of sleeve teeth are provided and are evenly arranged along the inner wall of the connected workpiece.

[0009] The beneficial effects of the utility model are as follows: the utility model can ensure a close fit with the coupler gear by connecting the sleeve teeth evenly arranged in the workpiece, ensuring that the teeth of the coupler can be subjected to force at the same time when rotating in one direction, providing protection for the coupler gear and increasing the durability of the special tool.

[0013] Example 1

[0014] like Figures 1 to 2 As shown, the utility model discloses a special tool for torque of a generator drive gear coupler, and the technical solution adopted is that it includes a 3 / 8 short socket head 1, a connecting processing part 2 and a sleeve tooth 3. One end of the 3 / 8 short socket head 1 is welded to one end of the connecting processing part 2, and a sleeve tooth 3 is provided on the inner wall of the end of the 3 / 8 short socket head 1 away from the connecting processing part 2. The connecting processing part 2 is made of 45 steel, and the inner wall is formed into the sleeve tooth 3 by turning and cutting. There are several sleeve teeth 3, which are evenly arranged along the inner wall of the connecting processing part 2. An anti-rust layer 4 is provided on the 3 / 8 short socket head 1, and the anti-rust layer 4 is an oxide film formed by bluing treatment on the surface of the 3 / 8 short socket head 1.

[0015] The working principle of the utility model is as follows: the 3 / 8 short socket head 1 is made of 45 steel and is turned, the connecting workpiece 2 is made of 45 steel, and the turning and cutting belts are used to form the sleeve teeth 3 parts, the 3 / 8 short socket head 1 is put on the connecting workpiece 2 thick end after assembly and welding, the connecting workpiece 2 thin end is inserted into the 3 / 8 short socket head 1 for assembly and welding to form a finished part, the surface of the finished part is ground and polished, and then bluing is performed evenly on the 3 / 8 short socket head 1 after grinding. When in use, the 3 / 8 short socket head 1 is connected to the input shaft of the generator. When the generator rotates, the evenly arranged sleeve ruler 3 can fit closely with the gear on the coupler to ensure that the teeth of the coupler can be subjected to force at the same time when rotating in one direction, providing protection for the coupler gears and increasing the durability of the special tool.
