Description

Technical Field

[0001] The invention relates to a novel air-cooled vibration motor, which is mainly used as a vibration source on vibration equipment in coal, electric power, chemical industry and the like, and belongs to the technical field of vibration equipment. Background Art

[0002] At present, in my country's coal, power and other industries, vibration motors are widely used as vibration sources for vibration equipment due to their simple structure and convenient maintenance and installation. However, the vibration motors rely on the centrifugal force of the eccentric block to generate vibration force at high frequency, which is easy to generate heat when frequently started. In addition, the vibration motors themselves have no heat dissipation device and rely entirely on the natural heat dissipation of the casing, so the heat dissipation is not good, which affects the service life. Now there is a particular need for a new type of vibration motor with a simple structure and its own heat dissipation function. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a novel vibration motor with a simple structure and a heat dissipation function.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve its technical problem is: a new type of air-cooled vibration motor, which is composed of an adjustable eccentric block, a fixed eccentric block, a rotating shaft, a fan blade, a bearing, an end cover, a terminal box, a rotor core, a stator core, a machine base, a vent cap and a sealing cover, and is characterized in that: a stator core 9 and a rotating shaft 3 are installed inside the machine base 10, a rotor core 8 is installed in the middle of the rotating shaft 3 and passes through the inside of the stator core 9, end covers 6 are installed at both ends of the machine base 10, bearings 5 ​​are installed in the end covers 6, the two ends of the rotating shaft 3 pass through the bearings 5 ​​respectively, and the two ends of the rotating shaft 3 passing through the bearings 5 ​​are successively equipped with fan blades 4, fixed eccentric blocks 2 and adjustable eccentric blocks 1, a sealing cover 12 is connected to the end cover 6 to seal the rotating shaft 3 inside, a vent cap 11 is installed on the sealing cover 12, and a terminal box 7 is provided on the upper part of the machine base 10.

[0005] Compared with the prior art, the present invention adopts the above structure and has the following characteristics.

[0006] Compared with the prior art, the innovation of the present invention is that the vibration motor is equipped with fan blades, which are driven by the motor itself to rotate and bring wind, so as to dissipate heat and cool the bearing in time, prevent the bearing temperature from rising too fast and too high, and solve the problem that the vibration motor has poor heat dissipation and affects its service life.

[0007] Compared with the prior art, the present invention is provided with a ventilation cap on the vibration motor cover, which can dissipate internal heat to the outside, accelerate the heat dissipation speed, achieve better heat dissipation effect, extend the service life of the motor, reduce maintenance, reduce costs, and be safer and more reliable.

[0008] Compared with the prior art, the vibration motor of the present invention is equipped with a fan for air cooling, which solves the problem that the vibration motor is not suitable for use with the inverter due to heat dissipation problems, reduces failures caused by heating, thereby extending the service life of the motor, reducing maintenance, reducing energy consumption, saving production costs, and having a simple structure, which is safer and more reliable. The vibration motor with built-in air cooling is also a major innovation.

[0009] The invention adopts a novel air-cooled vibration motor, which is particularly suitable for use as a vibration source in vibration equipment such as coal, electric power, and chemical industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The working principle of the present invention is: under the control of electrical equipment, when the power is turned on, the rated voltage is applied to the stator core inside the motor, and the rotor core will drive the rotating shaft to rotate. By adjusting the angle between the eccentric block and the fixed eccentric block, the centrifugal force generated by rotating with the rotating shaft is used as the excitation vibration source. The rotating shaft drives the fan blades to rotate to cool the bearing on the end cover. The ventilation cap on the motor cover accelerates the heat dissipation, so that the motor has its own fan for air cooling, and also solves the problem that the vibration motor cannot be used in frequency conversion due to heat dissipation problems, reduces failures caused by heat, thereby extending the service life of the motor, reducing maintenance, reducing energy consumption, saving production costs, simple structure, simple installation and replacement, greatly reducing maintenance costs, and being safer and more reliable. A new type of air-cooled vibration motor has a simple structure, reduces maintenance, has low energy consumption, low production cost, long service life, is safer and more reliable, and is particularly suitable for use as a vibration source on vibration equipment such as coal, electricity, and chemical industry.
