Description

Technical Field

[0001] The invention relates to the technical field of motor protection equipment, in particular to an encoding motor with a heat dissipation protection structure. Background Art

[0002] In the field of motor protection equipment technology, encoder motors are a kind of precision mechanical equipment, which are widely used in various automatic control systems. However, during long-term operation, the encoder motors are prone to overheating because the heat generated inside them cannot be dissipated in time, which affects their performance and service life. In addition, when the motor is running, dust and impurities in the external environment can easily enter the motor, which will not only reduce the heat dissipation efficiency of the motor, but also cause wear on the mechanical parts of the motor, increasing maintenance costs.

[0003] Traditional encoder motor designs often ignore the importance of heat dissipation and protection, or use simple heat dissipation methods such as natural heat dissipation or fan heat dissipation, which are not effective under high load or long-term operation conditions. At the same time, the lack of effective dust prevention measures makes it easy for dust to accumulate inside the motor, further exacerbating the heat dissipation problem. Therefore, developing an encoder motor with efficient heat dissipation and protection functions is of great significance to improving the stability and reliability of the motor.

[0017] The present invention provides an encoder motor with a heat dissipation protection structure. It has the following beneficial effects:

[0018] 1. The encoder motor with a heat dissipation protection structure, when drawing cold air into the mounting cover through the heat dissipation groove, allows the air to enter the mounting cover through the filter holes on the filter ring, and filter the outside air through the filter holes, greatly reducing the possibility of dust entering the mounting cover, avoiding dust clogging the mounting cover and reducing the heat dissipation effect, and at the same time, it can also greatly reduce the problem of dust entering the motor body and affecting the service life of the motor body. At the same time, by designing a cooling ring, the outside air can enter the mounting cover and enter the inner side of the cooling ring through the gap between the filter ring and the motor body during the process of being transported outward, and the cooling ring allows the outside air to always move close to the outer surface of the motor body, thereby greatly promoting the cooling effect of the motor body. At the same time, the motor body can also be cooled more evenly, avoiding the problem of heat accumulation in the mounting cover and increasing the temperature of the motor body.

[0019] 2. For the encoder motor with a heat dissipation protection structure, when the outside air is transported through the cooling ring in the installation cover, the air will enter the space where the fan blades are located through the main groove of the cooling ring and then be discharged outward through the air outlet. Since a driving ring is arranged on the outside of the cooling ring and diffuser grooves are evenly arranged on the cooling ring, a part of the air will be separated and discharged outward through the diffuser grooves when the air circulates in the cooling ring, thereby producing a linear guiding effect on the gas, and cooperating with the main groove to accelerate the flow speed of the gas in the installation cover, that is, the air circulation on the outer surface of the motor body is accelerated, thereby quickly cooling the motor body and preventing heat from accumulating on the outer surface of the motor body to reduce the heat dissipation effect.

[0020] 3. The encoder motor with a heat dissipation protection structure has an inner wall of the filter ring that is set to a wavy shape. Therefore, the elastic tube will intermittently contact and squeeze the inner wall of the filter ring when it rotates with the rotation of the mounting plate. The elastic tube is only squeezed and deformed. When the deformation force of the elastic tube reaches the maximum, the dredging hole on the elastic tube will coincide with the filter hole on the filter ring. At this time, the air pressure inside the elastic tube enters the filter hole through the dredging hole, thereby generating a blowing force outward on the filter hole, thereby intermittently cleaning the filter hole when the motor body is working, further preventing the problem of the filter hole being blocked and unable to be cleaned in time to reduce the heat dissipation effect. At the same time, when the elastic tube is squeezed, the support plate inside it will be driven to squeeze to both sides along the inside of the elastic tube, thereby ensuring that the elastic tube always maintains a good deformation force, thereby allowing the dredging hole to be accurately aligned with the filter hole, that is, greatly improving the effectiveness of cleaning the filter hole.

[0033] A cleaning mechanism 6, which is fixedly installed inside the heat dissipation mechanism 5 and is also arranged outside the motor body 3, and is used to remove dust from the heat dissipation mechanism 5;

[0034] The heat dissipation mechanism 5 includes a heat dissipation groove 51, which is opened through the outer surface of the mounting cover 2. A plurality of heat dissipation grooves 51 are arranged at fixed intervals around the central axis of the mounting cover 2. Fan blades 52 are arranged inside the mounting cover 2. The fan blades 52 are rotatably connected to the tail shaft of the motor body 3 on the side away from the front panel 1. An air outlet 53 is arranged on the outer side of the fan blade 52. The air outlet 53 is opened through the outer surface of the mounting cover 2 on the side away from the front panel 1.

[0035] A filter ring 54 is fixedly connected to the inner surface of the mounting cover 2, and a filter hole 55 is penetrated through the outer surface of the filter ring 54. The filter hole 55 is arranged directly opposite to the heat dissipation slot 51. A plurality of filter holes 55 are arranged at fixed intervals on the inner side of the same heat dissipation slot 51, and a group of filter holes 55 are arranged on the inner side of the same heat dissipation slot 51. Multiple groups of filter holes 55 are arranged at fixed intervals around the central axis of the filter ring 54.

[0036] A cooling ring 56 is provided on the side of the filter ring 54 away from the front panel 1, and the inner surface of the cooling ring 56 is arranged in parallel with the rear outer surface of the motor body 3, that is, the inner surface of the cooling ring 56 and the rear outer surface of the motor body 3 are the same at every distance, and a connecting column 57 is fixedly connected to the inner surface of the cooling ring 56 close to the motor body 3, and one end of the connecting column 57 away from the cooling ring 56 is fixedly connected to the rear outer surface of the motor, and a mainstream groove 58 is opened through the side of the cooling ring 56 close to the fan blade 52.

[0037] During operation, when the motor body 3 is in a normal working state, it is inside the mounting cover 2, providing protection for the motor body. When the motor starts to run, it will drive the transmission rod 4 to rotate through its rotating shaft to provide power for production. At the same time, when the motor starts, it will also drive the fan blades 52 to rotate. When the fan blades 52 start to rotate, air will be drawn from the mounting cover 2 and transported to the outside of the mounting cover 2 through the air outlet 53, so that the interior of the mounting cover 2 is in a negative pressure state, so that the mounting cover 2 draws the outside cold air into the inside through the heat dissipation groove 51, and discharges it to the outside through the air outlet 53 to realize gas circulation, and then the motor body 3 is cooled by the outside cold air, so as to prevent the motor body 3 from overheating during operation and affecting its life and performance. When the cold air is drawn into the mounting cover 2 through the heat dissipation groove 51, the air will pass through the filter ring 54 The filter hole 55 enters the interior of the mounting cover 2, and the outside air is filtered through the filter hole 55, which greatly reduces the possibility of dust entering the mounting cover 2, avoids dust clogging the mounting cover 2 and reducing the heat dissipation effect, and at the same time can also greatly reduce the problem of dust entering the motor body 3 and affecting the service life of the motor body 3. At the same time, by designing the cooling ring 56, the outside air can enter the mounting cover 2 and enter the inner side of the cooling ring 56 through the gap between the filter ring 54 and the motor body 3 during the process of being transported outward, and the cooling ring 56 makes the outside air always move close to the outer surface of the motor body 3, thereby greatly promoting the cooling effect of the motor body 3, and at the same time can also cool the motor body 3 more evenly, avoiding the problem of heat accumulation in the mounting cover 2 and increasing the temperature of the motor body 3.

[0038] Second embodiment: Figures 1 to 8 As shown, a diffuser groove 59 is provided through the inner surface of the cooling ring 56 close to the motor body 3. The diffuser groove 59 is arranged in a circular hole shape. A plurality of diffuser grooves 59 are provided at fixed intervals around the central axis of the cooling ring 56. The outer surface of the cooling ring 56 is rotatably connected to a drive ring 510. The outer surface of the drive ring 510 is fitted on the inner surface of the mounting cover 2 away from the front panel 1.

[0039] A gap is reserved between the inner surface of the driving ring 510 close to the fan blade 52 and the outer surface of the cooling ring 56 close to the fan blade 52. The driving ring 510 is arranged on the outside of the diffuser groove 59, and the outer surface of the driving ring 510 close to the fan blade 52 is symmetrically fixed with a connecting plate 511.

[0040] The inner end of the connecting plate 511 is fixedly connected to a connecting rod 512 , and one end of the connecting rod 512 away from the connecting plate 511 is fixedly connected to a connecting ring 513 . The connecting ring 513 is fixedly connected to the outer surface of the rotating shaft on the side of the motor body 3 close to the fan blades 52 .

[0041] During operation, when the outside air is transported through the cooling ring 56 in the mounting cover 2, it will enter the space where the fan blades 52 are located through the main groove 58 of the cooling ring 56 and then be discharged outward through the air outlet 53. Since a driving ring 510 is arranged on the outer side of the cooling ring 56 and diffuser grooves 59 are evenly arranged on the cooling ring 56, a part of the gas will be separated when the air circulates in the cooling ring 56 and discharged outward through the diffuser grooves 59, thereby producing a linear guiding effect on the gas, and cooperating with the main groove 58 to accelerate the flow speed of the gas in the mounting cover 2, that is, the air circulation on the outer surface of the motor body 3 is accelerated, so as to achieve the problem of quickly cooling the motor body 3 and preventing heat from accumulating on the outer surface of the motor body 3 to reduce the heat dissipation effect.

[0042] The third embodiment: Figures 1 to 8 As shown, the cleaning mechanism 6 includes a snap ring 61, which is fixedly snapped onto the outer surface of the driving ring 510 away from the fan blades 52, and the side of the snap ring 61 away from the driving ring 510 is slidably fitted onto the surface of the filter ring 54 away from the front panel 1.

[0043] An adapter plate 62 is fixedly connected to the inner surface of the clamping ring 61. Two adapter plates 62 are symmetrically arranged on the inner surface of the clamping ring 61. One end of the adapter plate 62 away from the clamping ring 61 is fixedly connected to a mounting plate 63. The mounting plate 63 is arranged on the outside of the motor body 3. An elastic tube 64 is fixedly connected to the outer surface of the mounting plate 63. The interior of the elastic tube 64 is arranged to be hollow. A dredging hole 65 is penetrated by the outer surface of the elastic tube 64. The dredging hole 65 is arranged in alignment with the filter hole 55. The inner surface of the filter ring 54 is arranged to be wavy.

[0044] The outer surface of the mounting plate 63 is fixedly connected with a mounting strip 66, which is arranged inside the elastic tube 64. The outer surface of the mounting strip 66 is fixedly clamped with a support plate 67, which is arranged as an elastic plate.

The outer end of the support plate 67 is slidably connected to the inner surface of the elastic tube 64.

[0045] During operation, when the motor body 3 starts, it will also drive the connecting ring 513 to rotate, and then drive the driving ring 510 to rotate through the connecting rod 512 and the connecting plate 511. When the driving ring 510 starts to rotate, the clamping ring 61 will rotate along with its movement, and then the mounting plate 63 will be driven to rotate through the adapter plate 62, so that when the motor starts to run, the mounting plate 63 is driven to rotate along the central axis of the motor body 3 on the outside of the motor body 3. When the mounting plate 63 rotates, the elastic tube 64 on the mounting plate 63 will start to rotate. At the same time, since the inner wall of the filter ring 54 is set to a wavy shape, the elastic tube 64 will intermittently contact and squeeze the inner wall of the filter ring 54 when it rotates with the rotation of the mounting plate 63. However, the elastic tube 64 is squeezed and deformed. When the elastic tube 64 is deformed, When the deformation force of the tube 64 reaches the maximum, the dredging hole 65 on the elastic tube 64 will coincide with the filter hole 55 on the filter ring 54. At this time, the air pressure inside the elastic tube 64 enters the filter hole 55 through the dredging hole 65, thereby generating a blowing force outward on the filter hole 55, thereby intermittently cleaning the filter hole 55 when the motor body 3 is working, further preventing the filter hole 55 from being blocked and unable to be cleaned in time to reduce the heat dissipation effect. At the same time, when the elastic tube 64 is squeezed, the support plate 67 inside it will be driven to squeeze toward both sides along the inside of the elastic tube 64, thereby ensuring that the elastic tube 64 always maintains a good deformation force, thereby allowing the dredging hole 65 to be accurately aligned with the filter hole 55, that is, greatly improving the effectiveness of cleaning the filter hole 55.
