Description

Technical Field

[0001] The present invention relates to the technical field related to motors, and in particular to a motor shaft assembly, a rotor mechanism and a motor. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It usually includes a stator, a rotor wrapped around the stator, and a casing wrapped around the rotor. There are many types of motors, among which permanent magnet motors are a common type. One of the reasons why permanent magnet motors are limited in power is that the motors are prone to get out of control when they heat up, and the enameled wires and permanent magnets are prone to overheating, which can lead to the inability to improve the efficiency of the motor.

[0003] At present, the existing permanent magnet motors usually have vents on the outer shell to achieve the circulation of internal and external gases, thereby achieving a cooling effect. However, the rotor is usually placed inside the stator, far away from the vents of the outer shell. Even if the gas between the inner and outer sides of the outer shell circulates, the cooling effect on the rotor is poor. Therefore, it cannot achieve a good overall cooling effect, and the operation of the permanent magnet motor will still be unstable. In addition, the existing permanent magnet motor has one end with a cooling fan, and the bearing connected to the internal shaft is set in the wind cover. The wind cover needs to be removed when the shaft is oiled, and the wind cover needs to be installed again after the oiling is completed. This makes it inconvenient to lubricate the bearings in the wind cover, and this operation is too time-consuming and labor-intensive, which greatly reduces the user experience.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

A liquid storage chamber 102 for storing coolant is provided inside the shaft 101. The inner walls of the liquid storage chamber 102 on both sides are fixedly connected with S-shaped inner slow plates 103.

The inner push block 112 moves to the right and can push the thermal grease in the storage bottle 110 to enter the inside of the feed tray 113 upward. At this time, the feed hole 114 transports the thermal grease to the surface of the heat pipe 108, and the thermal grease will automatically adhere to the surface of the heat pipe 108 as the shaft 101 rotates. Finally, the thickness of the thermal grease on the surface of the heat pipe 108 is trimmed by the smearing plate 115, and the thermal grease is kept evenly applied, so that the heat dissipation efficiency of the shaft 101 itself is greatly improved, which further improves the service life of the motor.

[0024] A rotor mechanism includes a rotor assembly 2, wherein the rotor assembly 2 includes a rotor 201, the rotor 201 is fixedly sleeved on the outer wall of the middle section of a rotating shaft 101, a cooling chamber 202 is provided inside the rotor 201, and a dredging hole 203 is provided on the lower surface of the inner cavity of the cooling chamber 202; a rotor fan 204 is fixedly sleeved on the outer walls at both ends of the rotating shaft 101, and opposite sides of the rotor fan 204 are respectively fixedly connected to the two side surfaces of the rotor 201, a permanent magnet 205 is embedded in the inner side of the side away from each other of the rotor fans 204, and a magnetic isolation ring 206 is provided in the middle position of the side away from each other of the two rotor fans 204.

[0025] Among them, through the set rotor assembly 2, first, the dredging hole 203 can transmit the coolant in the liquid storage chamber 102 to the inside of the cooling chamber 202 through the main delivery hole 104, and the array combination of the multi-layer cooling chamber 202 can cause the coolant to continuously flow through the inside of each cooling chamber 202 when the rotor 201 rotates, and at the same time realize the continuous cooling of the inside of the rotor 201 by the coolant, and then the rotor fan 204 can self-dissipate heat on the surface of the rotor 201 when the rotor 201 rotates, and finally the heat dissipation hole 207 can cause the air flow in the motor to pass through and take away the heat from the outside of the rotor 201, so that the heat dissipation rate of the entire rotor 201 is greatly improved by synchronously cooling the inside and outside of the rotor 201, and at the same time, compared with the existing natural heat dissipation method, it is more efficient and practical.

[0026] A motor comprises a casing 3, which is mounted on the outside of two bearings 106, with a fan cover 4 fixedly mounted on the right end of the casing 3; three heat sinks 5 are fixedly connected to the inner wall of the casing 3, and the three heat sinks 5 are fixedly connected to a stator 6 at one end opposite to each other, two assembly bases 7 are fixedly connected to the front and rear sides of the bottom of the casing 3, and a lubrication component 8 is embedded in the top of the right side of the casing 3.

[0027] The lubrication assembly 8 includes an auxiliary hole 801, which is opened on the upper surface of the right end of the casing 3. An oil storage tank 802 is embedded in the top of the right side of the casing 3. An oil inlet 803 is embedded on the left side of the upper surface of the oil storage tank 802. A limiting tube 804 is embedded on both sides of the bottom of the inner cavity of the oil storage tank 802. An oil delivery hole 805 is opened at the bottom of the two limiting tubes 804 facing each other. A suitable rod 806 is inserted into the inner cavity of each limiting tube 804. A cotton brush 807 is fixedly connected to one end of each suitable rod 806 close to the right side bearing 106; each suitable rod 80 6 is provided with a transfer hole 808 connected with the oil delivery hole 805 and the inner cavity of the cotton brush 807, and each cotton brush 807 is provided with a plurality of oil outlet holes 809 at the middle position of one side close to the bearing 106, the upper ends of the two suitable rods 806 are fixedly connected with an inner connecting plate 810, and a return spring 811 is fixedly connected between the lower surface of the inner connecting plate 810 and the bottom surface of the inner cavity of the oil storage tank 802, and the upper surface of the left end of the inner connecting plate 810 is fixedly connected with an inner slave tube 812, and a cotton core 813 is embedded in the inner slave tube 812, and a finger plate 814 is fixedly sleeved on the outer wall of the inner slave tube 812 at its upper end; Among them: through the provided lubrication component 8, first pressing the finger plate 814 can drive the inner slave tube 812 and the inner connecting plate 810 to move downward at the same time, and the inner connecting plate 810 moving downward can drive the two positioning rods 806 and the two cotton brushes 807 to move downward at the same time, when the transfer hole 808 in the two positioning rods 806 is flush with the position of the oil delivery hole 805, the oil delivery hole 805 can transfer the lubricating oil in the oil storage tank 802 to the inside of the cotton brush 807 through the transfer hole 808, and then the oil outlet hole 809 transfers the lubricating oil to the two side surfaces of the bearing 106, and then the rotation of the rotating shaft 101 can drive the inner ring of the bearing 106 and the internal ball to rotate, and at this time the cotton brush 807 can apply the lubricating oil to the surface of the bearing 106, so that the self-lubrication of the bearing 106 is quickly completed. The oiling is automatic, and this oiling method saves time and effort. After the oiling is completed, the finger plate 814 is loosened, and the return spring 811 will push the inner connecting plate 810 and the two positioning rods 806 to move upward at the same time. The upward movement of the two positioning rods 806 can drive the two cotton brushes 807 to move upward to the initial position, so that the cotton brushes 807 can be guaranteed to be separated from the surface of the bearing 106. Finally, the cotton core 813 can monitor the remaining amount of lubricating oil inside the oil storage tank 802 in real time. When the user touches the leakage end of the cotton core 813 with his finger, there is no lubricating oil on the surface of the finger, which indicates that there is a lack of lubricating oil in the oil storage tank 802. At this time, the lubricating oil is transported to the inside of the oil storage tank 802 through the oil inlet 803, which can facilitate the user to replenish the lubricating oil in time, enable the lubrication component 8 to be used continuously, and greatly improve the practicality of the motor.

[0028] Among them, through the provision of the heat sink 5 and the heat sink fan 107, firstly, the heat sink 5 can contact the surface of the stator 6 in multiple directions, so that the stator 6 can be effectively initially cooled, and then the heat sink fan 107 will rotate along with the rotation of the rotating shaft 101. The rotation of the heat sink fan 107 can efficiently extract the heat inside the motor, so as to ensure the stable operation of the motor itself.

[0029] During operation, the shaft 101 dissipates heat: first, the coolant in the liquid storage chamber 102 can dissipate the initial heat inside the shaft 101, and then the heat pipe 108 can dissipate the secondary heat on the surface of the shaft 101. Finally, when the temperature inside the motor rises again, the air bag 111 will expand due to the heat and push the inner push block 112 to move to the right. The inner push block 112 moves to the right and can push the thermal grease in the storage bottle 110 upward into the inside of the feed tray 113. At this time, the feed hole 114 transports the thermal grease to the surface of the heat pipe 108. The thermal grease will automatically adhere to the surface of the heat pipe 108 as the shaft 101 rotates. Finally, the thickness of the thermal grease on the surface of the heat pipe 108 is trimmed by the smearing plate 115, and the thermal grease is kept evenly applied, so that the heat dissipation efficiency of the shaft 101 itself is greatly improved. Heat dissipation of rotor 201: First, the dredging hole 203 can transfer the coolant in the liquid storage chamber 102 to the inside of the cooling chamber 202 through the main delivery hole 104. The array combination of the multi-layer cooling chamber 202 can cause the coolant to continuously flow through the inside of each cooling chamber 202 when the rotor 201 rotates, and at the same time, the coolant continuously cools the inside of the rotor 201. Then, the rotor fan 204 can dissipate heat on the surface of the rotor 201 when the rotor 201 rotates. Finally, the heat dissipation hole 207 can cause the airflow in the motor to pass through and take away the heat from the outside of the rotor 201. In this way, the heat dissipation rate of the entire rotor 201 is greatly improved by synchronously cooling the inside and outside of the rotor 201. Motor heat dissipation: First, the heat dissipation plate 5 can contact the surface of the stator 6 in multiple directions, so that the stator 6 can be effectively initially cooled. Then, the heat dissipation fan 107 rotates along with the rotation of the rotating shaft 101. The rotation of the heat dissipation fan 107 can efficiently extract the heat inside the motor, so as to ensure the stable operation of the motor itself. Oiling the bearing 106: First, pressing the finger plate 814 can drive the inner follower tube 812 and the inner connecting plate 810 to move downward at the same time. The downward movement of the inner connecting plate 810 can drive the two positioning rods 806 and the two cotton brushes 807 to move downward at the same time. When the transfer hole 808 in the two positioning rods 806 is flush with the position of the oil delivery hole 805, the oil delivery hole 805 can transfer the lubricating oil in the oil storage tank 802 to the inside of the cotton brush 807 through the transfer hole 808, and then the oil outlet hole 809 transfers the lubricating oil to the two side surfaces of the bearing 106, and then the rotation of the shaft 101 can drive the inner ring of the bearing 106 and the internal ball to rotate. At this time, the cotton brush 807 can apply the lubricating oil to the surface of the bearing 106, so that the bearing 1 is quickly completed. 06 is automatically oiled, and this oiling method saves time and effort. After the oiling is completed, release the finger plate 814, and the reset spring 811 will push the inner connecting plate 810 and the two positioning rods 806 to move upward at the same time. The upward movement of the two positioning rods 806 can drive the two cotton brushes 807 to move upward to the initial position, so that the cotton brushes 807 can be guaranteed to be separated from the surface of the bearing 106. Finally, the cotton core 813 can monitor the remaining amount of lubricating oil inside the oil storage tank 802 in real time. When the user touches the leakage end of the cotton core 813 with his finger, there is no lubricating oil on the surface of the finger, which means that there is a lack of lubricating oil in the oil storage tank 802. At this time, the lubricating oil is transported to the inside of the oil storage tank 802 through the oil inlet 803, which can facilitate the user to replenish the lubricating oil in time and enable the lubrication component 8 to be used continuously.
