Description

Technical Field

[0001] This utility model relates to the field of flange technology, and in particular to an explosion-proof flange for motors. Background Technology

[0002] During the operation of an electric motor, the flange is a key component connecting various parts of the motor, and its performance directly affects the overall safety and stability of the motor. Traditional motor flanges have many problems when facing harsh working conditions such as high temperature, high pressure and complex mechanical stress.

[0003] On the one hand, ordinary flanges have limited strength and are prone to deformation or even cracking when subjected to large external impacts or internal pressure fluctuations, leading to the exposure of internal motor components and causing safety accidents. They cannot meet explosion-proof requirements. On the other hand, motors generate a lot of heat during operation. Traditional flanges have poor high-temperature resistance and their material properties will rapidly decline under high-temperature conditions, further reducing their structural strength and sealing performance, and affecting the normal operation and service life of the motor.

[0004] Therefore, an explosion-proof flange for motors is proposed here to solve the aforementioned problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies and solve the problem that traditional flanges have poor high-temperature resistance due to the large amount of heat generated during motor operation, this utility model provides an explosion-proof flange for motors.

[0006] This utility model is achieved using the following technical solution:

[0007] An explosion-proof flange for an electric motor includes a flange body with four mounting holes arranged around the center circumference of the flange body. A reinforcing ring is provided on the surface of the flange body. The reinforcing ring is annular and is integrally connected to the flange body.

[0008] The flange body is also equipped with a high-temperature resistant device, which is used to improve the high-temperature resistance of the flange body.

[0009] The high-temperature resistant device includes a cavity, which is located inside the flange body and is filled with coolant. The flange body has a filling port on its surface, which is connected to the cavity. A plug is provided at the filling port, and the plug is threadedly connected to the flange body.

[0010] The lower surface of the plug is provided with an O-ring, which is fitted onto the lower end of the plug.

[0011] The flange body is provided with symmetrical sealing rings on the front and back sides, and the sealing rings are integrated with the flange body.

[0012] A limiting ring is provided inside the mounting hole, and the limiting ring is fixed to the inner wall of the mounting hole. The limiting ring is made of wear-resistant rubber.

[0013] The flange body has symmetrically arranged sealing gaskets on its front and back sides. Each sealing gasket is installed between the reinforcing ring and the sealing convex ring and is bonded to the flange body.

[0014] The present invention has the following advantages over the prior art:

[0015] 1. By installing a high-temperature resistant device inside the flange body, the cavity in the high-temperature resistant device is filled with coolant. The coolant in the high-temperature resistant device can absorb the heat generated by the motor operation in time, reduce the temperature of the flange body, and avoid the material performance degradation caused by high temperature, thereby ensuring the stability and reliability of the flange in high-temperature environment.

[0016] 2. By setting a reinforcing ring on the surface of the flange body, the design of the reinforcing ring significantly enhances the structural strength of the flange body, enabling it to withstand greater external impact and internal pressure, effectively preventing flange cracking, and greatly improving the explosion-proof safety of the motor.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4As shown, an explosion-proof flange for an electric motor includes a flange body 1. The flange body 1 is the basic structural component of the entire explosion-proof flange, undertaking the important tasks of connecting other components of the motor and transmitting force and torque. It also provides a basic platform for the installation and fixing of other components, ensuring the integrity and stability of the entire flange structure. The flange body 1 has four mounting holes arranged around the center circumference of the flange body 1. These mounting holes facilitate accurate connection and fixing with other components. A reinforcing ring 12 is provided on the surface of the flange body 1. The reinforcing ring 12 is annular and is integrally connected to the flange body 1. When the flange is subjected to external force, the reinforcing ring 12 can share part of the stress, dispersing the stress over a larger area and reducing the stress concentration per unit area of ​​the flange body 1. It is like adding a reinforcing beam to the structure, enhancing the load-bearing capacity of the entire structure, enabling the flange to maintain structural integrity under complex working conditions and avoiding damage caused by excessive local stress.

[0025] The presence of the reinforcing ring 12 significantly enhances the overall strength and rigidity of the flange body 1, effectively resisting external impact and internal pressure, preventing the flange from deforming and cracking under complex working conditions, thereby improving explosion-proof performance.

[0026] The flange body 1 is also equipped with a high-temperature resistant device, which is used to improve the high-temperature resistance of the flange body 1.

[0027] The high-temperature resistant device includes a cavity 14, which is located inside the flange body 1 and is filled with coolant. The flange body 1 has a filling port 13 on its surface, which is connected to the cavity 14. A plug 3 is provided at the filling port 13, and the plug 3 is threadedly connected to the flange body 1. The threaded connection of the plug 3 facilitates the addition and replacement of coolant.

[0028] The lower surface of the plug 3 is provided with an O-ring 31, which is fitted onto the lower end of the plug 3. The O-ring 31 provides a good seal, preventing coolant leakage. When the motor is running, it generates heat, which the coolant can absorb and carry away some of the heat, reducing the temperature of the flange body 1 and thus effectively improving its high-temperature resistance.

[0029] The flange body 1 has symmetrical sealing rings 11 on its front and back sides, and the sealing rings 11 are integrally connected to the flange body 1. The presence of the sealing rings 11 increases the sealing performance of the flange at the contact surfaces with other components, effectively preventing media leakage and improving the overall sealing performance of the motor.

[0030] A limiting ring 4 is provided inside the mounting hole, and the limiting ring 4 is fixed to the inner wall of the mounting hole. The limiting ring 4 is made of wear-resistant rubber. The limiting ring 4 not only restricts the position of the connecting parts and prevents them from shaking in the mounting hole, ensuring the stability of the connection, but the wear-resistant rubber material also reduces the friction between the connecting parts and the inner wall of the mounting hole, reducing wear and extending service life.

[0031] The flange body 1 has symmetrically arranged sealing gaskets 2 on its front and back sides. Each sealing gasket 2 is installed between the reinforcing ring 12 and the sealing convex ring 11, and the sealing gasket 2 is adhered to the flange body 1. The sealing gasket 2 further enhances the sealing performance of the flange, effectively preventing the medium from leaking from the flange edge and ensuring the stability of the internal environment of the motor.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
