Description
Technical Field
[0001] This utility model relates to the field of drive motor technology, and in particular to a motor with a noise reduction mechanism. Background Technology
[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors (symbol M) and generators (symbol G). Electric motors utilize the principle of electromagnetic induction to generate force through the interaction of current and magnetic field, converting electrical energy into mechanical energy.
[0003] Traditional motors have the following drawbacks: 1. The noise reduction effect during operation is not significant, and the cooling effect is poor even with improved waterproof sealing. Therefore, those skilled in the art have provided a motor with a noise reduction mechanism to solve the problems mentioned in the background art. Utility Model Content
[0004] The main objective of this invention is to provide a motor with a noise reduction mechanism to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor with a noise reduction mechanism, comprising an outer shell, an inner shell, and a motor body; a rear end cover is engaged at one end of the outer shell, a semiconductor cooler is mounted on the outer side of the rear end cover through mounting holes, and a thermostat is mounted on one end of the semiconductor cooler through screws; an inner shell is welded inside the outer shell, and a polyurethane interlayer is filled between the inner shell and the outer shell; sound-absorbing sponge blocks are equidistantly bonded to the inner wall surface of the inner shell; the ends between the outer shell and the inner shell are sealed by an interlayer sealing plate; a front end cover is engaged and fixed on one side of the interlayer sealing plate through sealing bolts; the motor body is mounted inside the front end cover through a mounting seat; a front sealing plate is mounted on the outer side of the front end cover through screws, and a bushing is fitted at the axial center of the front sealing plate.
[0006] As a further embodiment of this utility model: the cooling end of the semiconductor cooler is located inside the inner shell, and the heating end of the semiconductor cooler is located outside the rear end cover and is provided with heat dissipation fins. The cooling end of the semiconductor cooler absorbs heat from inside the inner shell, and the heat dissipation fins of the heating end facilitate the release of heat.
[0007] As a further improvement of this utility model: the detection end of the temperature controller is located inside the inner casing, and the output end of the temperature controller is electrically connected to the input end of the semiconductor cooler through a wire.
[0008] As a further improvement of this utility model: a sealing gasket is adhered to the outer edge of the inner side of the front cover, and the sealing gasket is specifically made of silicone rubber material and has a corresponding screw hole.
[0009] As a further improvement of this utility model, the interlayer sealing plate is provided with a screw hole facing the sealing bolt.
[0010] As a further embodiment of this utility model: the output shaft of the motor body passes through the bushing and a coupling sleeve is welded to the end. Locking bolts are installed at equal intervals on one side of the outer side of the coupling sleeve. The coupling sleeve and locking bolts facilitate connection with the transmission shaft of the mechanical equipment, thereby driving the transmission shaft of the mechanical equipment to rotate.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The coupling sleeve and locking bolt facilitate connection to the drive shaft of the mechanical equipment, driving the drive shaft to rotate. The sealing gasket is made of silicone rubber, which is highly elastic, tough, and corrosion-resistant, improving the sealing performance at the engagement point. During operation, the motor body first absorbs motor noise through sound-absorbing sponge blocks. Due to the double-layer structure design of the motor housing, the middle cavity is filled with a polyurethane interlayer to further block motor noise, significantly improving the noise reduction effect.
[0012] 2. The thermostat automatically controls the semiconductor cooler to maintain a constant temperature inside the inner casing. The cooling end of the semiconductor cooler absorbs heat from inside the inner casing, while the heat dissipation fins at the heating end facilitate the release of heat. This reduces the temperature while improving the waterproof sealing of the motor, thus preventing aging or even damage caused by high temperatures. Attached Figure Description
