Description

Technical Field

[0002] A motor is a device that converts electrical energy into mechanical energy. It is mainly composed of a stator, a rotor, a casing and end covers. Servo motors are widely used in various control systems. They can convert the input voltage signal into a mechanical output on the motor shaft, dragging the controlled components to achieve the control purpose. Servo motors are divided into DC and AC. The earliest servo motors were general DC motors. When the control accuracy is not high, general DC motors are used as servo motors. Structurally, a DC servo motor is a low-power DC motor. Its excitation mostly uses armature control and magnetic field control, but armature control is usually used.

[0003] The end cover of the existing motor is usually fixed to the motor casing by a number of fastening screws. Since the motor makes a rotary motion, the whole body vibrates greatly and generates heat inside when working. The heat dissipation method of ordinary motors is usually to dissipate heat through a fan located at the tail of the motor, a heat dissipation strip of the motor casing and a heat dissipation port at the tail end of the rear cover. The heat dissipation port of the motor end cover cannot meet the heat dissipation needs of the motor when working for a long time. The heat dissipation effect through the heat dissipation port of the motor end cover is not obvious. Therefore, a motor end cover that can dissipate heat is proposed to solve the above-mentioned problems. Summary of the invention

[0036] Example 1

[0037] Reference Figure 1 The present invention discloses a motor end cover, including an end cover body 100. In the present embodiment, the end cover body 100 includes an end cover member 101. The end cover member 101 is mainly a cover plate with one end of an output rod of the motor, which is used to seal the end of the motor. The whole is supported by aluminum alloy, and the material strength is relatively high. The whole is a circular plate. A bearing mounting ring 102 is also provided on the end cover member 101. The bearing mounting ring 102 is arranged at the center position of the entire end cover member 101 for bearing installation. A covering plate member 103 is also provided on the end cover member 101. The covering plate member 103 is installed on the upper surface of the end cover plate 101a. The covering plate member 103 is used to wrap the entire end cover plate 101a.

[0038] Furthermore, the present invention also includes a heat dissipation component 200. In this embodiment, the heat dissipation component 200 includes a plurality of heat sinks 201 arranged on the lower surface of the end cover plate 101a and a temperature sensor 202 arranged on the end cover plate 101a. A plurality of heat sinks 201 are provided, and a circular array is provided on the lower end surface of the end cover plate 101a. A heat sink sub-fin is provided on each heat sink 201, and a plurality of heat sink sub-fins are provided, thereby increasing the heat dissipation area of ​​the heat sink 201. At the same time, the temperature sensor 202 is connected to each heat sink 201 through an electrical conductor for monitoring the temperature of the heat sink 201.

[0039] Furthermore, the present invention also includes a cooling assembly 300. In this embodiment, the cooling assembly 300 includes a cooling component 301 disposed in the end cover 101. The cooling component 301 is used to remove heat from the heat sink 201 by water cooling. A connecting cooling component 302 connected to the cooling component 301 is provided on the bearing mounting ring 102.

[0040] Preferably, the connecting cooling component 302 includes an annular heat dissipation pipeline opened on the bearing mounting ring 102 and a radiator arranged at the end of the annular heat dissipation pipeline. The radiator is arranged away from the motor and can also be arranged close to the motor as needed. The annular heat dissipation pipeline is connected to the radiator. After the coolant passes through the radiator, heat exchange is performed between the radiator and the air, thereby achieving cooling.

[0041] Furthermore, a circulation component 303 for circulating the coolant is provided on the cooling component 301 , and the temperature sensor 202 is electrically connected to the cooling component 301 .

[0042] Preferably, in the present embodiment, the end cover 101 comprises an end cover plate 101a and a connecting ring plate 101b arranged on one side surface of the end cover plate 101a, a matching groove body 101c for installing the cooling component 301 is formed on the side surface of the end cover plate 101a close to the heat sink 201, the covering plate 103 is sealingly fastened on the end cover plate 101a, an entry groove 103a is opened on the end cover plate 101a, the entry groove 103a and the matching groove body 101c are respectively opened on two sides of the end cover plate 101a, and a sealing gasket is provided between the covering plate 103 and the entry groove 103a, and the sealing gasket seals the gap between the entry groove 103a and the covering plate 103.

[0043] Furthermore, in this embodiment, the cooling component 301 includes a first flow channel 301a arranged on the end cover plate 101a, a cooling flow channel 304 connected to the first flow channel 301a, and a second flow channel 301b connected to the outlet end of the cooling flow channel 304. The first flow channel 301a is connected to the water outlet end of the annular heat dissipation pipe, the other end of the second flow channel 301b is connected to the water inlet end of the annular heat dissipation pipe, and the other end of the first flow channel 301a is connected to the inlet of the cooling flow channel 304. The first flow channel 301a, the second flow channel 301b, the cooling flow channel 304 and the annular heat dissipation pipe are all filled with coolant, thereby forming a closed heat dissipation circuit.

[0044] Preferably, a plurality of cooling channels 304 are provided, and the plurality of cooling channels 304 are arranged in an arc-shaped array along the end cover plate 101a, and in the present embodiment, the plurality of cooling channels 304 are arranged in a form of being connected end to end in sequence, wherein the cooling channels 304 located at the end are respectively connected to the first channel 301a and the second channel 301b.

[0045] Furthermore, every two adjacent cooling channels 304 are centrally symmetrically arranged. In the present embodiment, the cooling channels 304 include a main channel 304a provided on the matching groove body 101c, a plurality of first circulation monomers 304b and second circulation monomers 304c connected to the main channel 304a, and a slide groove 304d provided on the first circulation monomers 304b and the second circulation monomers 304c. The main channel 304a is used to connect the plurality of cooling channels 304 and serves as the main coolant flow direction, thereby guiding the flow of the coolant.

[0046] Furthermore, both ends of the first circulation monomer 304b and the second circulation monomer 304c are connected to the main channel 304a. When the coolant flows, a part of the coolant flows forward through the main channel 304a, and the other part of the coolant enters the first circulation monomer 304b and the second circulation monomer 304c, and then flows out of the first circulation monomer 304b and the second circulation monomer 304c and enters the main channel 304a.

[0047] Furthermore, a baffle plate is slidably connected in the slide groove 304d, and the length of the baffle plate is shorter than the length of the slide groove 304d. The baffle plates are respectively arranged in the slide groove 304d located in the first circulation monomer 304b and the slide groove 304d located in the second circulation monomer 304c, and are divided into a first baffle plate 305 and a second baffle plate 306. The first baffle plate 305 and the second baffle plate 306 play a role in adjusting the flow diameter of the main channel 304a.

[0048] When the first baffle plates 305 and the second baffle plates 306 are located close to each other, the flow diameter of the main channel 304a will be reduced. At this time, more coolant will enter the first circulation monomer 304b and the second circulation monomer 304c, thereby expanding the range of the coolant flow and increasing the cooling range.

[0049] Furthermore, a plurality of first circulation monomers 304b and second circulation monomers 304c are respectively arranged on both sides of the main channel 304a and are inclined. The first circulation monomers 304b and the second circulation monomers 304c are symmetrically arranged. When observed from directly above the first circulation monomers 304b and the second circulation monomers 304c, the angle formed between the length direction of the first circulation monomers 304b and the horizontal direction is 40°-46°, preferably 45° in the present embodiment. At this time, it can be ensured that the liquid can flow into the first circulation monomers 304b and the second circulation monomers 304c, and the inclination directions of the first baffle plate 305 and the second baffle plate 306 are respectively consistent with the inclination directions of the first circulation monomers 304b and the second circulation monomers 304c.

[0050] Furthermore, a sliding member 400 for driving the baffle plate to slide is provided on the end cover plate 101a. In the present embodiment, the sliding member 400 includes a first sliding plate 401 connecting a plurality of first baffle plates 305, a second sliding plate 402 connected to a plurality of second baffle plates 306, a first sliding arc rod 403 arranged on the first sliding plate 401, and a second sliding arc rod 404 arranged on the second sliding plate 402. The first sliding plate 401 and the second sliding plate 402 are both slidably connected to the outer wall of the surface of the entrance groove 103a, and maintain a sealed fit with the outer wall of the entrance groove 103a, to ensure that when the first sliding plate 401 and the second sliding plate 402 slide, the coolant will not flow out from the gap between the entrance groove 103a and the first sliding plate 401 and the second sliding plate 402.

[0051] In this embodiment, the circulation component 303 includes a cooling air pump 303a arranged on the first flow channel 301a, a water wheel 303b rotatably connected to each main flow channel 304a, a rotating gear 303c coaxially arranged with the water wheel 303b, and a plurality of blades arranged on the outside of the water wheel 303b. The water wheel 303b will change the flow rate of the coolant after rotation. The water wheel 303b is arranged at the outlet position of the main flow channel 304a, and the water wheel 303b is arranged closer to one of the side walls of the main flow channel 304a to ensure that the impact of the water flow can cause the water wheel 303b to rotate.

[0052] Preferably, the rotating gear 303c is disposed in the entry groove 103a, and the rotating shaft between the rotating gear 303c and the water wheel 303b passes through the end cover plate 101a.

[0053] A connecting rod 303d is extended from the first sliding arc rod 403 and the second sliding arc rod 404 toward the rotating gear 303c, and a rack 303e meshing with the rotating gear 303c is provided on the connecting rod 303d. The temperature sensor 202 controls the start and stop of the water wheel 303b.

[0054] Specifically, in order to control the start and stop of the water wheel 303b, a magnet is provided on the end cover plate 101a, and the magnet is connected to the end cover plate 101a through an elastic plate. In the present embodiment, the elastic plate is a copper alloy plate, which has certain flexibility. The magnet is arranged near the lower end of the water wheel 303b, and a control circuit is extended from the temperature sensor 202 to control the magnet. When the temperature sensor 202 monitors that the temperature of the heat sink 201 is normal, the magnet is magnetized through the control circuit, and is adsorbed on the water wheel 303b, and the water wheel 303b is fixed so that the water wheel 303b does not rotate. When the water wheel 303b needs to rotate, the control circuit causes the magnet to lose its magnetic force, and then does not adsorb the water wheel 303b, and is moved away from the water wheel 303b under the action of the elastic plate, and the water wheel 303b can rotate at this time.

[0055] Operation process: when the motor end cover is installed on the motor, the heat sink 201 at the lower end of the end cover plate 101a can conduct the heat generated inside the motor to the outside and collect most of the heat. When the heat is within the normal range (that is, when the temperature of the heat sink 201 does not reach the threshold), the temperature sensor 202 determines that the temperature is not overheated at this time. At this time, the temperature sensor 202 controls the magnet through the control circuit to magnetize the magnet, and adsorbs the water wheel 303b, and fixes the water wheel 303b so that the water wheel 303b does not rotate. At this time, the first baffle plate 305 and the second baffle plate 306 are in a state of being away from each other. At this time, the coolant circulates along the first flow channel 301a, the cooling flow channel 304, the second flow channel 301b, and the annular heat dissipation pipeline under the action of the cooling air pump 303a, and flows slowly.

[0056] At this time, most of the coolant will flow along the central main channel 304a, and a small amount of the coolant will enter the first circulation monomer 304b and the second circulation monomer 304c on both sides, and maintain a forward flow direction in the first circulation monomer 304b and the second circulation monomer 304c, and after flowing out of the first circulation monomer 304b and the second circulation monomer 304c, it will merge into the coolant in the main channel 304a. This process is a normal flow heat dissipation process.

[0057] During the above process, if part of the coolant refluxes in the main channel 304a due to external vibration interference during use of the motor, the refluxed part of the coolant will reversely enter the first circulation monomer 304b or the second circulation monomer 304c from the outlet of the first circulation monomer 304b or the second circulation monomer 304c. At this time, when the coolant refluxes, it will rush outward along the inclination angle of the first baffle plate 305 or the second baffle plate 306 and converge into the main channel 304a. The flow direction of this coolant is opposite to the reflux direction of the coolant, thereby preventing the reflux flow. The above process exists in each of the first circulation monomer 304b and the second circulation monomer 304c, thereby preventing the coolant from refluxing and stagnating, and preventing it from being unable to take away the heat in time.

[0058] When the temperature of the heat sink 201 gradually increases and exceeds the threshold, the temperature sensor 202 receives a signal and transmits the signal to the control circuit. The control circuit stops the magnet from being magnetized, and the magnet no longer restricts the rotation of the water wheel 303b. The water wheel 303b rotates under the flow of the coolant, and the rotation of the water wheel 303b further promotes the flow of the coolant, accelerating the flow of the coolant, thereby putting the entire cooling regulation in a dynamic process.

[0059] At the same time, the rotation of the water wheel 303b will drive the rotation of the rotating gear 303c, and the rotation of the rotating gear 303c will cause the first sliding arc rod 403 and the second sliding arc rod 404 to slide through the rack 303e on the first sliding arc rod 403 and the second sliding arc rod 404, so that the first sliding arc rod 403 and the second sliding arc rod 404 are brought closer to each other, and then the first baffle plate 305 and the second baffle plate 306 are pulled closer to each other. At this time, the width of the main channel 304a becomes narrower, and most of the coolant will enter the first circulation monomer 304b and the second circulation monomer 304c. At this time, the flow path of the coolant increases in disguised form, and the time that the coolant stays in the first circulation monomer 304b and the second circulation monomer 304c will increase accordingly, so that more heat can be taken away.

[0060] In the above process, since most of the liquid enters the first circulation monomer 304b and the second circulation monomer 304c, the impact of the coolant in the main channel 304a on the water wheel 303b becomes smaller, and when the coolant rushes out of the first circulation monomer 304b and the second circulation monomer 304c, the impact force of the coolant in the main channel 304a will increase, thereby ensuring the rotation of the water wheel 303b, so that the water wheel becomes a dynamic speed change process, thereby continuously adjusting the distance between the first baffle plate 305 and the second baffle plate 306, thereby controlling the flow rate of the coolant and achieving dynamic balance regulation.

[0061] Example 2

[0062] Reference Figure 2 , this embodiment is different from the first embodiment in that: the present invention further discloses a motor, including a motor body 500. In this embodiment, the motor body 500 includes a motor outer shell 501, a motor inner shell 502 installed in the motor outer shell 501, and a heat-insulating space arranged between the motor inner shell 502 and the motor outer shell 501. A protrusion is formed on the outer wall of the motor inner shell 502. The protrusion is annular and equidistantly arranged on the motor inner shell 502. The protrusion abuts against the inner wall of the motor outer shell 501. After abutting, there is a heat-insulating space between every two adjacent protrusions, thereby isolating a certain amount of external temperature interference. The motor inner shell 502 and the motor outer shell 501 are also detachably connected, and the motor outer shell 501 is detachably connected to the end cover plate 101a, and the two are connected by bolts.

[0063] Furthermore, the motor of this embodiment also includes a stator-rotor assembly 600.

[0064] Furthermore, a rotating bearing is provided at one end of the upper end of the motor shaft after passing through the end cover plate 101 a , and the rotating bearing is installed in cooperation with the bearing mounting ring 102 .

[0065] The rest of the structure is the same as that of Example 1.

[0066] When installing the motor, the operator first installs the motor inner housing 502 in the motor outer housing 501, then installs the stator body 601 in the motor inner housing 502, and then installs the rotor body 602, and then installs the above-mentioned end cover to the end position of the motor and fixes and locks it with bolts.
