Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a heat dissipation box of a reducer. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is commonly used as a reduction gear between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator.

[0003] According to a planetary reducer housing (Announcement No.: CN218480137U) disclosed in the above application, by turning the knob to open the threaded hole, thermal conductive silicone oil is injected into the heat dissipation box, and a heat sink is set on the top of the heat dissipation box to accelerate the heat dissipation speed of the planetary reducer housing and increase the service life of the reducer.

[0004] However, in actual use, the above-mentioned equipment only relies on thermal silicone oil and heat sinks to dissipate heat for the reducer. Since the heat emitted by the equipment is not evenly distributed on the outside of the equipment, this may lead to uneven heat dissipation of the equipment, causing the local temperature of the reducer to be too high when working, resulting in damage to the internal parts of the reducer. In view of this, we propose a reducer heat dissipation box. Utility Model Content

[0010] Preferably, there are two groups of fans and rotating shafts, and the two groups of fans and rotating shafts are mirror-imaged and distributed at both ends of the outer wall of the lower end of the shell, and the ends of the two groups of rotating shafts away from the motor are fixedly connected to pulleys, and the two groups of pulleys are connected by a transmission belt, so that the swing of one group of fans can drive the swing of the other group of fans, so that the heat can be dissipated at both ends of the heat pipe.

[0011] Preferably, the air guide plate is configured as an arc plate, the width of the air guide plate is greater than the width of the heat dissipation tube, the length of the air guide plate is equal to the length of the heat dissipation tube, and the opening of the arc plate faces upward, so that the hot air emitted from the heat dissipation tube can be guided to the outside of the heat conduction tube by the air guide plate, preventing the heat emitted by the heat dissipation tube from causing the heat conduction tube to heat up.

[0012] Preferably, a through groove is provided on the outer wall of the slide, the slider is configured as a cylinder, and the slider is slidingly connected to the inner wall of the groove, the pulley fixedly connected to the slider is rotatably connected to the outer wall of the shell, and when the stirring rod rotates, the slider is rotated by the pulley and the transmission belt, and the slider moves in the groove while rotating, thereby pushing the slide to swing, and then causing the fan to swing around the rotating shaft.

[0013] Preferably, the heat pipe is spirally wound around the heat pipe, one end of the heat pipe passes through the end of the heat dissipation pipe close to the motor, and the other end of the heat pipe passes through the narrow end of the conical pipe, so that the water in the heat pipe can drive the stirring blade to rotate through the motor, thereby causing the cooling water to flow through the heat dissipation pipe in the heat pipe.

[0015] 1. The heat dissipation box of the reducer is started by the motor, which makes the stirring rod rotate. The rotation of the stirring rod drives the fixed ring to rotate the stirring blade, so that the stirring blade pushes the cooling water in the heat dissipation tube to move. The tapered tube enables the cooling water to be better pushed into the heat conduction pipe, so that the cooling water continuously circulates in the heat conduction pipe and the heat dissipation tube. The air guide plate can also guide the hot air on the heat dissipation tube from both ends to prevent the hot air emitted from the heat dissipation tube from heating the heat conduction pipe, so that the cooling water can better and more evenly dissipate the heat of the reducer.

[0016] 2. The heat dissipation box of the reducer rotates the slider through the pulley and the transmission belt when the stirring rod rotates.

There are two groups of fans, which are connected to the transmission belt through the pulley, so that the two groups of fans can swing to dissipate heat to the heat pipe.

[0025] In one embodiment of the present invention, the heat pipe 61 is attached to the outer wall of the heat tube 5, the heat pipe 61 passes through and is fixedly connected to the air guide plate 62, the outer wall of the heat pipe 61 passes through and is fixedly connected to the heat dissipation tube 63, and the outer wall of the shell 1 is fixedly connected to the motor 64.

[0026] In one embodiment of the present invention, a stirring rod 65 is fixedly connected to the output end of a motor 64. The stirring rod 65 passes through the outer wall of the heat dissipation tube 63 and is fixedly connected to a fixing ring 67. The outer wall of the fixing ring 67 is fixedly connected to a stirring blade 68. A conical tube 66 is provided at the end of the heat dissipation tube 63 away from the motor 64.

[0027] The outer wall of the pulley 71 away from the stirring rod 65 is connected to a slider 73, and the outer wall of the slider 73 is slidably connected to a slide plate 74. The outer wall of the slide plate 74 is fixedly connected to the fan 75, and the lower end of the fan 75 is fixedly connected to a rotating shaft 76. The rotating shaft 76 is rotatably connected to the outer shell 1, so that when the motor 64 drives the stirring blade 68 to circulate the cooling water in the heat pipe 61, the stirring rod 65 drives the slider 73 to drive the slide plate 74 to rotate through the transmission belt 72 and the pulley 71, causing the fan 75 to swing, thereby blowing away the hot air emitted from the heat pipe 61, so that the heat dissipation effect of the box is better.

[0028] In an embodiment of the present utility model, there are two groups of fans 75 and rotating shafts 76, and the two groups of fans 75 and rotating shafts 76 are mirror-imaged and distributed at both ends of the outer wall of the lower end of the shell 1, and the ends of the two groups of rotating shafts 76 away from the motor 64 are fixedly connected to the pulleys 71, and the two groups of pulleys 71 are connected by transmission belts 72, so that the swing of one group of fans 75 can drive the swing of the other group of fans 75, so that the two ends of the heat pipe 61 can be cooled, and the heat dissipation effect of the box is better.

[0029] In an embodiment of the present utility model, the air guide plate 62 is set as an arc plate, the width of the air guide plate 62 is greater than the width of the heat dissipation tube 63, the length of the air guide plate 62 is equal to the length of the heat dissipation tube 63, and the opening of the arc plate is facing upward, so that the hot air emitted from the heat dissipation tube 63 can be guided by the air guide plate 62 to the outside of the heat pipe 61, preventing the heat emitted by the heat dissipation tube 63 from causing the heat pipe 61 to heat up, thereby reducing the heat dissipation effect of the box.

At this time, the reduction assembly 2 works to generate heat, and the motor 64 is started to rotate the stirring rod 65. The rotation of the stirring rod 65 drives the fixing ring 67 to rotate the stirring blade 68, so that the stirring blade 68 pushes the cold water in the heat dissipation tube 63 to move, and the conical tube 66 enables the cooling water to be better pushed into the heat conduction pipe 61, so that the cooling water circulates continuously in the heat conduction pipe 61 and the heat dissipation tube 63, and the air guide plate 62 can also disperse the cooling water. The hot air on the heat tube 63 is discharged from both ends to prevent the hot air from heating the heat pipe 61, so that the cooling water can dissipate heat to the reducer better and more evenly. When the stirring rod 65 rotates, the slider 73 is rotated through the pulley 71 and the transmission belt 72.

There are two groups of fans 75, which are connected to the transmission belt 72 through the pulley 71, so that the two groups of fans 75 can swing to dissipate heat to the heat pipe 61.
