Description

Technical Field

[0001] The present invention relates to the technical field of planetary speed reducers, and specifically to a permanent magnet planetary speed reducer for constant speed conveying. Background Art

[0002] Planetary speed reducers are widely used industrial products that can reduce the speed of motors while increasing the output torque. Planetary speed reducers can be used as supporting components in industries such as lifting, excavation, transportation, and construction. Currently, permanent magnet motors are often combined with planetary speed reducers and are specifically used in constant speed conveying scenarios. Permanent magnet motors themselves have good speed regulation performance and rotational speed stability. Combined with the precise transmission of planetary speed reducers, they can achieve precise constant speed conveying, ensuring extremely small speed fluctuations during the conveying process and meeting occasions with high requirements for conveying accuracy.

[0003] However, the following deficiencies exist in the prior art: During the constant speed conveying process of permanent magnet planetary speed reducers, due to factors such as tooth meshing friction, bearing friction, and eddy current losses of permanent magnets, a large amount of heat will be generated. If heat dissipation is not timely, it will cause the temperature of the speed reducer to rise, thereby affecting its performance and lifespan.

[0004] When the planetary speed reducer is in use, there is a lack of fault judgment, and it cannot give a fault prompt in a timely manner. Moreover, its internal structure is complex, and maintenance requires professional personnel to disassemble it, which is time-consuming and costly.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to the attached Figure 1 - attached Figure 8 As shown, the present invention provides a technical solution: a permanent magnet planetary reducer for constant-speed conveying, including a housing mechanism 1, a power mechanism 2, and a main mechanism 3. The power mechanism 2 and the main mechanism 3 are both fixedly installed inside the housing mechanism 1, and one end of the power mechanism 2 is fixedly connected to one end of the main mechanism 3.

[0023] Example 1, according to Figures 7 - 8As shown, the main body mechanism 3 includes a sun gear 301 and a liquid storage tank 313. A set of planetary gears 302 are meshed with the outer surface wall of the sun gear 301. A planetary carrier 303 is arranged on both sides of the set of planetary gears 302. A ring gear 304 is meshed with the outer surface wall of the set of planetary gears 302. Connecting heads 305 are fixedly installed at both ends of the ring gear 304. Heat dissipation coatings 309 are arranged on the outer surface walls of the ring gear 304 and the two connecting heads 305.

A pressure relief valve 320 is fixedly installed inside one of the connecting heads 305. A vibration sensor 312 is fixedly installed on the outer surface wall of one of the connecting heads 305.

[0024] The effects achieved by the entire Embodiment 1 are as follows: Among the components described above, the high-speed rotational power output by the permanent magnet motor 201 is transmitted to the sun gear 301 of the planetary speed reducer. The sun gear 301 drives the planetary gears 302 to rotate around the sun while rotating on their own axes. The planetary gears 302 mesh with the ring gear 304. Since the ring gear 304 is usually fixed, the movement of the planetary gears 302 is converted into the low-speed rotation of the planetary carrier 303, so that a reduced speed and amplified torque can be obtained on the output shaft 307 of the planetary carrier 303 to meet the requirements of constant-speed conveying for low speed and large torque. And the characteristics of the permanent magnet motor 201 are used to ensure the constant-speed performance during the conveying process. By setting the heat dissipation coating 309, the heat dissipation efficiency is effectively improved. The pressure generated when the gear set is used and the pressure inside the cavity formed by the ring gear 304 and the two connecting heads 305 are respectively detected by the temperature sensor 310 and the pressure sensor 311. Then, a pressure relief valve 320 is set. When the pressure in the cavity exceeds the preset threshold, the pressure relief valve 320 is used to relieve the pressure to improve the safety of the equipment. When the detected temperature exceeds the preset threshold, the detection signal is received and processed by the control panel 319, and the circulating pump 314 is started to convey the coolant inside the liquid storage tank 313 into the cavity to cool the gear set and reduce wear during use.

[0026] The entire Example 1 - Figure 8 The achieved effects are as follows: Among the components mentioned above, the input shaft 306 and the output shaft 307 are respectively used to connect the permanent magnet motor 201 and the external conveying device, and transmit the high-speed rotating power output by the permanent magnet motor 201 to the external conveying device after reducing the speed through the gear set, so as to achieve the constant speed performance during the conveying process, and use the bearings 308 to reduce the friction and wear of the shaft during rotation; use the liquid level sensor 317 to monitor the remaining amount of the coolant inside the liquid storage tank 313 for timely replenishment, use the refrigeration sheet 318 to cool the coolant to improve the cooling effect when the coolant circulates, use the noise monitoring module 103 to monitor the noise generated by the use of the gear set to predict the faults of the gear set or the bearings 308, when the operating temperature of the gear set is too high, automatically start the high-efficiency heat dissipation fan 105 to accelerate the air circulation inside the housing and reduce the environmental temperature inside the housing 101, and then use the circulating pump 314 to convey the coolant to cool the inside of the gear set to achieve the purpose of rapid cooling; then use the control panel 319 to receive the monitoring signals of the noise monitoring module 103, the temperature sensor 310, the pressure sensor 311, the vibration sensor 312, and the liquid level sensor 317, and issue corresponding instructions after signal processing.

[0027] Example 3, according to Figure 9As shown, the noise monitoring module 103 is used to monitor the noise during the use of the gear set and send the monitoring signal to the control panel 319 for processing; The temperature sensor 310 is used to monitor the temperature inside the gear ring 304 and send the monitoring signal to the control panel 319 for processing. After being processed by the control panel 319, it controls the opening and closing of the high-efficiency radiator fan 105 and the circulation pump 314; The pressure sensor 311 is used to monitor the pressure inside the gear ring 304 and send the pressure signal to the control panel 319. After being processed by the control panel 319, it controls the opening and closing of the pressure relief valve 320; The vibration sensor 312 is used to monitor the vibration during the use of the gear set and send the detection signal to the control panel 319 for processing; The liquid level sensor 317 is used to monitor the remaining liquid in the liquid storage tank 315 and send the detected value to the control panel 319 for processing; The refrigeration sheet 318 is controlled by the control panel 319 to open and close, and is used to reduce the temperature of the liquid inside the liquid storage tank 313.

[0028] The effect achieved by the entire embodiment 3 is as follows: First, the control panel 319 receives the monitoring signals of the noise monitoring module 103, the temperature sensor 310, the pressure sensor 311, and the vibration sensor 312; Then, it processes the received signals. When the detection signals of the noise monitoring module 103 and the vibration sensor 312 exceed the preset threshold, a warning is issued to predict gear or bearing failures; Finally, an instruction is issued through the control panel 319; When the temperature detected by the temperature sensor 310 exceeds the preset threshold, the high-efficiency radiator fan 105 and the circulation pump 314 are automatically started, and when the detected temperature returns to the preset threshold, they are turned off; When the pressure value detected by the pressure sensor 311 exceeds the preset threshold, the pressure relief valve 320 is automatically started, and when the detected pressure returns to the preset threshold, it is turned off; The refrigeration sheet 318 and the circulation pump 314 are opened and closed synchronously.

[0029] The working principle of the whole device is as follows: When this speed reducer is in use, first, the whole device is disassembled into a housing mechanism 1, a power mechanism 2 and a main body mechanism 3. The power mechanism 2 and the main body mechanism 3 are fixedly installed inside the housing mechanism 1 to play a protective role. The power mechanism 2 provides power support to drive the output of the main body mechanism 3. A coupling 202 is fixedly installed at the output end of the permanent magnet motor 201, and the coupling 202 is fixedly connected to the input shaft 306. The high-speed rotating power output by the permanent magnet motor 201 is transmitted to the sun gear 301 of the planetary speed reducer. The sun gear 301 drives the planetary gear 302 to rotate around its own axis while revolving. The planetary gear 302 meshes with the ring gear 304. Since the ring gear 304 is usually fixed, the movement of the planetary gear 302 is converted into the low-speed rotation of the planet carrier 303. Thus, a reduced speed and amplified torque are obtained on the output shaft 307 of the planet carrier 303 to meet the requirements of constant-speed conveying for low speed and large torque, and the characteristics of the permanent magnet motor 201 are used to ensure the constant-speed performance during the conveying process. In terms of data monitoring, a temperature sensor 310 and a pressure sensor 311 are respectively arranged on the outer wall of the ring gear 304 to monitor the temperature and pressure data during the operation of the gear set, and the monitoring signals are transmitted to the control panel 319 for processing. When the operating pressure is too high, on the one hand, a signal instruction is sent through the control panel 319 to automatically start the high-efficiency cooling fan 105 to accelerate the air circulation inside the housing 101 for heat dissipation purposes. On the other hand, an instruction is sent through the control panel 319 to turn on the circulation pump 314. The circulation pump 314 is used to transport the coolant inside the liquid storage tank 313 to the cavity formed by the ring gear 304 and the connector 305 to cool the gear set. A refrigerating sheet 318 is fixedly installed on the inner wall of the liquid storage tank 313, which is responsible for cooling the coolant inside the liquid storage tank 313 to improve the cooling effect on the gear set. Then, the liquid level sensor 317 is used to monitor the remaining amount of the coolant inside the liquid storage tank 313 to facilitate timely replenishment of the coolant. Secondly, the pressure sensor 311 is used to detect the pressure inside the ring gear 304, and the pressure signal is transmitted to the control panel 319 and analyzed. When the pressure exceeds the set safety threshold, the pressure relief valve 320 is used to release the pressure to improve the safety of equipment use. In addition, a vibration sensor 312 is fixedly installed on the outer wall of a connector 305. The vibration sensor 312 is used to monitor the vibration sensation during the operation of the gear set, and cooperate with the noise monitoring module 103 to monitor the use noise of the gear set, so as to predict the faults of the gear set or the bearing 308. In terms of structural settings, by providing a heat dissipation coating 309 on the outer walls of both the gear ring 304 and the connector 305, the heat dissipation efficiency can be effectively improved. A set of ventilation mesh plates 106 are fixedly arranged inside the outer shell 101. The set of ventilation mesh plates 106 are arranged opposite to each other. The heat dissipation air box 104 is arranged on one side of the ventilation mesh plate 106. After the high-efficiency cooling fan 105 blows air into the interior of the outer shell 101, the warm air inside it is discharged from the mesh holes of the ventilation mesh plate 106 arranged oppositely, achieving the purpose of heat dissipation. Then, a set of feet 102 are fixedly installed on the outer wall of the outer shell 101, facilitating the installation of this planetary speed reducer.
