Description

Technical Field

[0001] The utility model relates to the technical field of flange equipment, and particularly relates to a double-flange structure for an electric motor. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil, i.e., a stator winding, to generate a rotating magnetic field and acts on a rotor to form a magnetoelectric driving rotating torque. An electric motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying wire in a magnetic field is related to the direction of the current and the direction of the magnetic induction line. The working principle of an electric motor is the force exerted by a magnetic field on a current, which causes the electric motor to rotate. A flange, also known as a flange plate or a collar, is a part used to connect shafts to each other, and there are also flanges used at the inlets and outlets of equipment for connecting two pieces of equipment, such as a reducer flange. However, when using an electric motor flange, the outer disk and the inner disk are combined, and slots are opened at the sleeve, which makes the operation too complicated and the adaptability to production errors is relatively low.

[0003] In order to solve the above problems, in the prior art, the electric motor flange with the patent number CN209057036U discloses a structure including a bottom plate and a connecting pipe. One side of the surface of the bottom plate is communicated with one end of the connecting pipe. Both sides of the inner wall of the connecting pipe are fixedly connected with guiding blocks. A fixing groove is opened at the top of the inner wall of the connecting pipe. One side of the inner wall of the fixing groove is fixedly connected with a stabilizing plate, and one side of the stabilizing plate is fixedly connected with an elastic sheet. Through the fixing groove, the elastic sheet and the contact plate, the output shaft of the electric motor can be completely engaged with the contact plate, reducing the shaking when the connecting pipe is connected to the output shaft of the electric motor, effectively increasing the connection stability between the flange and the output shaft of the electric motor, and the overall structure of the device is simple. Through the guiding blocks on the inner wall of the connecting pipe, the output shaft can stably move down along the guiding blocks, so that the through groove opened on the surface of the output shaft can be completely penetrated by the inserting rod, which is easy for the staff to operate. However, this solution cannot connect two shafts with different sizes through a coupling, which is not convenient for customers to replace the rotating shafts with different sizes. Therefore, a double-flange structure for an electric motor is proposed for the above problems. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A double flange structure for a motor, comprising a first rotating shaft, a first flange cover, a first front end cover, a second rotating shaft, a first coupling and a second coupling. The right end of the first rotating shaft passes through the through hole of the first flange cover and is fixed in the first fixing port of the first coupling. A first connecting rod is provided at the right end of the first coupling, and the first connecting rod is inserted into the corresponding right connecting hole inside the second coupling. The left end of the second rotating shaft passes through the through hole of the first front end cover and is fixed in the second fixing port of the second coupling. A second connecting rod is provided at the left end of the second coupling, and the left end of the second connecting rod is inserted into the corresponding left connecting hole inside the first coupling. The first front end cover is installed outside the second coupling, and the left end of the first front end cover is fixedly connected to the right end of the first flange cover. The first flange cover is arranged outside the first coupling. The diameter of the first fixing port is different from that of the second fixing port, and the diameter of the first fixing port is smaller than that of the second fixing port.

The left end of the second coupling 6 is provided with a second connecting rod 61, and the left end of the second connecting rod 61 is inserted into the corresponding left connecting hole 52 inside the first coupling 5, which can increase the stability between the first coupling 5 and the second coupling 6. The first front end cover 3 is installed outside the second coupling 6.
