Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As shown in Figures 1-3, this utility model provides a technical solution: a large vibration motor with good heat dissipation and noise reduction effect, including a base 19, bearing outer cover I 18, bearing outer cover II 3, bearing inner cover I 14, bearing inner cover II 11, end cover I 16, end cover II 13, rotor 10, stator 9, bearing I 6, bearing II 17 and multiple sets of excitation blocks.

[0024] The base 19 adopts a cylindrical design. Unlike existing bases, it does not have a mounting base, which allows for a larger base volume and ample space for heat dissipation (large vibratory motors have larger stators and rotors, requiring more space for heat dissipation).

[0025] Multiple sets of excitation blocks are located on the central shaft of end cover I 16 and end cover II 13 respectively. Each set of excitation blocks includes two fixed excitation blocks 2 and two adjustable excitation blocks 1 with adjustable spacing. The excitation force during motor operation can be significantly reduced by multiple sets of excitation blocks. The mating surface of end cover II 13 and base 19 is provided with cylindrical holes. Cylindrical pins 7 are installed in the internal threads of the cylindrical holes for easy installation and positioning. A cable outlet cover 8 is installed on the base 19 for storing wires.

[0026] The end cover II13 located on the body (replacing the traditional end cover structure) adopts a unique shape design and is cast in one piece. It absorbs the shape characteristics of the traditional end cover, while eliminating the end cover. While serving the function of fixing the bearing, it can also achieve the function of wrapping and protecting the end cover. If the traditional end cover structure is used for large vibratory motors, the end cover is too large and the rigidity is insufficient, resulting in insufficient rigidity of the entire motor. The improved rigidity is greatly improved.

[0027] Meanwhile, the bottom of the end cover II13 is designed with a mounting base, which evenly distributes the load of the whole machine on both sides and improves stability; and it has a wider base area, which improves stability and can transmit the excitation force more effectively.

[0028] The stator 9 and rotor 10 are installed in the frame. The stator 9 is located in the middle of the frame 19 and surrounds the outside of the rotor 10. Bearing I6 and bearing II17 are respectively installed at both ends of the shaft of the rotor 10.

[0029] The outer and inner sides of the end cover II13 are respectively equipped with the bearing outer cover II3, the bearing inner cover II11, and the spacer II12. The bearing outer cover II3, the bearing inner cover II11, and the spacer II12 together form a mounting area, and the bearing I6 is located in this mounting area.

[0030] The outer and inner sides of end cover I16 are respectively equipped with bearing outer cover I18, bearing inner cover I14, and spacer I15. The bearing outer cover I18, bearing inner cover I14, and spacer I15 together form a mounting area, and bearing II 17 is located in this mounting area.

[0031] The motor employs a four-bearing support system. Traditional vibratory motors use a two-bearing support system. Larger vibratory motors are heavier, with larger rotors and shafts, resulting in greater excitation forces. Using a two-bearing structure leads to excessive weight and excitation force on each bearing. Because the shaft is longer, the two-bearing structure causes excessive shaft deflection. Furthermore, it requires larger bearings, reducing heat dissipation. These factors significantly reduce bearing lifespan, increase wear, cause excessive temperature, generate excessive noise, and disrupt stable operation.

[0032] The four-bearing support system allows for the use of smaller bearings, significantly increasing heat dissipation. The increased number of bearings also helps to distribute heat effectively, resulting in a substantial overall improvement in heat dissipation. Furthermore, the shaft load distribution is more uniform, the excitation force is more evenly distributed, and operation is more stable. This leads to lower operating temperature, reduced noise, less bearing wear, and increased bearing lifespan, which in turn extends the motor's lifespan and extends maintenance cycles.

[0033] End cover I16 is fixed to end cover II13, which is fixed to the base 19. An eye bolt 5 is installed on end cover II13.

[0034] The end cap II13 is provided with an oil cup hole for installing the oil cup 4. The lubricating oil in the oil cup 4 lubricates the bearing I6 through the oil cup hole.

[0035] The bearing outer cover I18 has an oil cup hole at its center for installing the oil cup 4. The lubricating oil in the oil cup 4 lubricates the bearing II17 through the oil cup hole.

[0036]

[0037] As shown in the table above, monitoring the temperature and noise levels of six sets of vibration motors (three sets each of ordinary motors and the motor in this case, with an ambient temperature of 25℃) revealed that the improved vibration motor in this case had an average operating noise level below 85dB (average value 80.3dB) and an average operating temperature of approximately 90℃ (average value 89℃). In contrast, the existing ordinary vibration motor had an average operating noise level of 98.7dB and an average operating temperature of 101.3℃.

[0038] In summary, the improved vibration motor has improved noise reduction by approximately 20% and heat dissipation by over 10%.
