Description

Technical Field

[0001] The invention belongs to the technical field of motors, and in particular relates to a flameproof motor casing. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motor is represented by the letter M (D in the old standard) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy.

[0003] In order to ensure the consistency of the motor's appearance during the production process, the motor end cover is basically aligned and close to the surface of the motor casing. When the motor fails, it is very troublesome to remove the end cover, and the motor may be damaged during the removal process, especially for explosion-proof motors.

[0004] In view of this, the present invention designs a highly sealed flameproof motor housing to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a highly sealed flameproof motor casing. By arranging a ring plate, an annular groove, a mounting plate and a disassembly plate, the front end cover and the inner end cover can be easily separated from the casing through the disassembly plate, while also increasing the sealing between the end cover and the casing, thereby solving the problem that the existing motor end cover is difficult to disassemble and the motor may be damaged during the disassembly process.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a highly sealed flameproof motor housing, comprising a housing and bolts;

[0008] The peripheral side surface of the housing is fan-shaped and fixed with four mounting plates, and the two sides of the housing are respectively fixed with a front end cover and an inner end cover, the front end cover and the inner end cover are symmetrically arranged, and one side of the front end cover is fixed with a ring plate and an ear plate;

[0009] Both end surfaces of the housing are provided with annular grooves, both end surfaces of the mounting plate are provided with grooves, and two through grooves are provided at positions corresponding to the grooves on the upper surface of the mounting plate, and a disassembly plate is slidably fitted inside the through grooves;

[0010] The disassembly plate comprises a first square block, a trapezoidal block is fixedly connected to the bottom of the first square block, a second square block is fixedly connected to the bottom of the trapezoidal block, and the second square block is located inside the groove and contacts the groove bottom of the groove;

[0011] The second square block and the ear plate are fixedly connected to the groove bottom of the groove by bolts.

[0012] Furthermore, the second square block, the ear plate and the groove bottom of the groove are all provided with threaded holes matching with the bolts.

[0013] Furthermore, the front end cover and the inner end cover are both provided with through holes matching the motor shaft.

[0014] Furthermore, the ring plate is located inside the annular groove, and the second square block is located inside the groove.

[0015] Furthermore, a plurality of heat dissipation fins are fixedly connected to the peripheral side surface of the housing, and a sealing gasket is provided between the ring plate and the annular groove.

[0016] The present invention has the following beneficial effects: the present invention arranges a ring plate, an annular groove, a mounting plate and a disassembly plate. When disassembling the end cover, the screws are unscrewed, and the first square block of the disassembly plate is hit gently with a hammer, so that the trapezoidal block is squeezed inward, thereby pushing the ring plate outward. The annular groove and the ring plate increase the sealing of the motor.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
