Description

Technical Field

[0001] The utility model relates to the technical field of induction heat treatment quenching of wind power gear rings, in particular to a quenching transformer for thin gear rings. Background Technique

[0002] At present, most gear ring quenching adopts single-head quenching, that is, only one inductor can be installed at each station, which results in relatively low production efficiency. To improve production efficiency, it is necessary to increase equipment and production personnel. In the existing equipment, the water circuit is complex. For relatively small gear rings, only single-head quenching can be used, and the quenching efficiency is not high within the same time.

[0003] The Chinese patent document with the authorization announcement number CN208173391U discloses "a high-efficiency high-frequency quenching transformer, which is characterized in that: it includes a secondary coil, a primary coil is arranged inside the secondary coil, a high-permeability magnetic core is arranged inside the primary coil, and silicone rubber is potted between the primary coil and the high-permeability magnetic core...". For the above technical solution, the following defects still exist in use:

[0004] At present, the commonly used quenching transformers are composed of multiple coils. Each coil needs to be cooled separately, the cooling water circuit is relatively complex, and the volume is relatively large. Because the load part of the wind power gear ring quenching needs to be inside the gear ring, it is very inconvenient if the quenching transformer used in practical equipment has a large volume.

[0005] Therefore, in order to reduce the volume of the quenching transformer for the wind power gear ring quenching load and simplify the cooling water circuit, the present application proposes a quenching transformer for thin gear rings. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a quenching transformer for thin gear rings, which solves the problems put forward in the above background technique.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme: a quenching transformer for thin gear rings, including an epoxy body, side baffles, second installation and fixing columns, first installation and fixing columns, a magnetic core, a secondary wire coil, a primary-secondary wire coil, and a turns ratio adjustment plate.

[0008] The side baffles are fixedly connected to the top and bottom of the epoxy body through the second installation and fixing columns; the magnetic core is installed on the side of the side baffle located inside the epoxy body through the first installation and fixing columns.

[0009] The secondary wire coil and the primary-secondary wire coil are arranged inside the epoxy body, and both the secondary wire coil and the primary-secondary wire coil are flat copper tubes, and the two are arranged in a spring spiral structure and cross each other.

[0010] The turns ratio adjustment plate is connected to the port of the secondary wire coil located outside the epoxy body.

[0011] A first water inlet, a second water inlet, a third water inlet, a first water return port, a second water return port, and a third water return port are inserted through the side wall of the epoxy body; the secondary wire coil is formed by winding a copper tube, and its two ends are connected to the first water inlet and the third water return port to form a one-in-one-out cooling water path; the primary-secondary wire coil is formed by welding a plurality of copper tubes, and its multiple ports are respectively connected to the second water inlet, the third water inlet, the first water return port, and the second water return port to form a two-in-two-out cooling water path.

[0012] Preferably, a capacitor input connector and a transmission connector are respectively inserted through the front wall and the side wall of the epoxy body.

[0013] Preferably, an O-ring is embedded on the side of the side baffle close to the epoxy body. The side baffle is in sealing connection with the epoxy body through the O-ring, and the O-ring is made of polyurethane material.

[0014] Preferably, the epoxy body is formed by potting the secondary wire coil and the primary-secondary wire coil with a sealed epoxy resin, and water inlet holes, water return holes, and holes for other joint components are reserved on the epoxy body shell.

[0015] Preferably, an insulating end piece is provided at the bottom of the primary-secondary wire coil, and the insulating end piece is made of polytetrafluoroethylene material; the magnetic core is in a cylindrical U shape.

[0016] Preferably, a fixed installation main vertical column is inserted longitudinally into the epoxy body, and the end of the fixed installation main vertical column is fixedly connected to the side baffle.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this thin-tooth-ring quenching transformer, by arranging the secondary wire coil and the primary-secondary wire coil in a spring spiral structure and intersecting with each other, the wire coils can be superimposed and distributed, thus greatly reducing the structure of the cooling water path and the volume occupied by the cooling water path. Moreover, the secondary wire coil and multiple primary-secondary wire coils are respectively independently connected to different water inlets and water return holes to form a total of three cooling water paths, greatly improving the cooling efficiency, achieving the effects of simplifying the cooling water path and improving the efficiency, thereby reducing the volume of the quenching transformer for the wind power tooth ring quenching load, facilitating the satisfaction of double-head induction quenching (usually only one inductor is installed for the quenching of a tooth ring, and only one tooth can be quenched each time. For double-head quenching, two inductors can be installed at a time, and two teeth can be quenched at a time), greatly improving the original production efficiency, reducing the equipment procurement cost, and the simplification of the water path also reduces the failure rate and maintenance cost of the equipment, which is beneficial for the use of gantry structure induction quenching machines or other non-standard induction quenching equipment, and has good practicability.
