Description

Technical Field

[0001] The present application relates to the technical field of motors, and in particular to a high heat dissipation motor with an indication function. Background Art

[0002] Among the vast number of driving sources currently, motors are more common. They are electromagnetic devices that use the law of electromagnetic induction to achieve electrical energy conversion or transmission. They drive objects through rotation to perform a series of operations.

[0003] Generally, the heat dissipation method of a motor is to connect its main shaft and fan blades coaxially, so that the rotating main shaft drives the fan blades to rotate synchronously, so that the fan blades blow air toward the motor housing and blow away the heat generated by the motor.

[0004] Regarding the above-mentioned related technologies, the inventors believe that: when the motor is cooled, the motor coaxially drives the fan blades to rotate, which makes the heat dissipation effect of the motor poor when used in a relatively hot environment and needs to be improved. Summary of the invention

[0005] In order to improve the heat dissipation effect of the motor in a relatively hot environment, the purpose of this application is to provide a high heat dissipation motor with an indication function.

[0006] The present application provides a high heat dissipation motor with an indication function, which adopts the following technical solution:

[0007] A high heat dissipation motor with an indication function comprises a body, a main shaft rotatably connected in the body, and a rear end cover sleeved on one end of the body, wherein one end of the main shaft rotatably connected in the rear end cover is coaxially connected to a driving gear, a side wall of the body facing the rear end cover is rotatably connected to a plurality of secondary shafts located around the driving gear, a driven gear meshing with the driving gear is coaxially connected to the secondary shaft, the diameter of the driving gear is larger than that of the driven gear, a fan blade is coaxially connected to one end of the secondary shaft away from the driven gear, and a plurality of air inlets are provided on the rear end cover.

[0008] By adopting the above technical solution, when the motor is used in a relatively hot environment, the motor drives the main shaft to rotate, the main shaft drives the driving gear to rotate, and the driving gear drives the driven gear to rotate. Then the secondary shaft is driven to rotate, so that the fan blades around the main shaft rotate, sucking in the outside air from the air inlet and blowing it to the body for heat dissipation. Therefore, by setting the driving gear and the driven gear, the rotation of the main shaft can drive the rotation of multiple secondary shafts, and then realize the rotation of multiple fan blades around the main shaft, so as to increase the heat dissipation range and wind force of the fan blades, thereby improving the heat dissipation effect of the motor in a relatively hot environment.

[0009] Optionally, bearing seats are provided on the side walls of the machine body and the inner walls of the rear end cover, both ends of the secondary shaft rotate in the bearing seats, one end of the secondary shaft located in the bearing seat is sleeved with a magnet, and a generator coil is provided on the bearing seat located in the rear end cover, and the generator coil is sleeved outside the magnet, and an indicator light electrically connected to the generator coil is provided on the circumferential side wall of the machine body.

[0010] By adopting the above technical solution, when the motor is used, the main shaft rotates while the secondary shaft also rotates, and one end of the secondary shaft located at the rear end cover drives the magnet to rotate in the generator coil, so that the magnetic flux of the generator coil changes. Then, an induced electromotive force and an induced current are generated to supply power to the indicator light, so that the indicator light lights up to remind the staff that the motor cooling fan is running normally and is dissipating heat, so that the operator can know in time that the motor is working normally.

[0011] Optionally, the secondary shaft slides in the bearing seat along its own axial direction, and one end of the secondary shaft slides through the rear end cover, and the end of the secondary shaft passing through the rear end cover is rotatably sleeved with a clamping cap, and the end of the secondary shaft passing through the rear end cover is sleeved with a spring, one end of the spring is arranged on the clamping cap, and the other end is arranged on the rear end cover, and the spring is used to pull the clamping cap to drive the driven gear and the driving gear on the secondary shaft to engage.

[0012] By adopting the above technical solution, when the motor is used in a non-hot environment, part of the locking cap is pulled away from the rear end cover to stretch the spring, thereby driving the secondary shaft to slide away from the body. This in turn drives the driven gear to disengage from the active gear, and then an external tool is clamped between the locking cap and the rear end cover to limit the locking cap from resetting under the action of the spring. Therefore, by providing the locking cap and the spring and utilizing the sliding of the secondary shaft in the bearing seat, part of the driven gear around the active gear can be disengaged by pulling part of the locking cap, thereby reducing the energy consumption of the motor in a non-hot environment, thereby achieving the effect of improving the motor driving efficiency.

[0013] Optionally, a plurality of guide rods are provided on the side wall of the abutting cap facing the rear end cover, and the guide rods surround the spring and slide through the rear end cover.

[0014] By adopting the above technical solution, when the abutting cap is pulled, the abutting cap drives the guide rod to slide out from the rear end cover to guide the sliding of the abutting cap. When the abutting cap is released, the spring can drive the abutting cap to reset, and under the sliding of the guide rod, the abutting cap is prevented from being stuck on the secondary shaft under the action of the spring.

[0015] Optionally, the rear end cover is provided with a connecting plate between the clamping cap and the rear end cover, the end of the spring away from the clamping cap is arranged on the connecting plate, the connecting plate is provided with an avoidance hole for the sliding of the secondary shaft, and the guide rods all slide through the connecting plate.

[0016] By adopting the above technical solution, when the clamping cap is pulled and slid synchronously, the connecting plate is slid in the direction away from the rear end cover, so that the compression spring of the connecting plate drives the clamping cap to move synchronously, driving the clamping cap to move synchronously away from the rear end cover, so that the driven gear is synchronously disengaged from the driving gear, thereby facilitating the synchronous disengagement of all driven gears from the driving gear.

[0017] Optionally, the middle section of the connecting plate is stepped, and the sliding friction resistance of the secondary shaft in the upper and lower parts of the stepped connecting plate is different. The connecting plate is used to drive the locking cap to slide successively, and to pull the driven gear on the secondary shaft to slide away from the driving gear successively.

[0018] By adopting the above technical solution, since the connecting plate is in a stepped shape, the connecting plate compresses the secondary shaft with smaller friction resistance to slide, and then pushes the part of the locking cap to slide away from the rear end cover, and the part of the compression spring below the step of the connecting plate does not push the locking cap to move, so that the locking cap on the rear end cover drives the driven gear to disengage from the driving gear, so that the part of the fan blades in the rear end cover stops rotating, so that the rotation of the main shaft only drives part of the fan blades to rotate, so as to reduce the energy consumption of the motor. Continuing to move the connecting plate in the direction away from the rear end cover can push the secondary shaft with larger friction resistance to slide, and drive the remaining locking cap to slide, so that the remaining driven gears are all separated from the driving gear. Therefore, by setting the connecting plate and utilizing the stepped shape of the connecting plate, the connecting plate can be partly separated from the driving gear in the process of moving away from the rear end cover, and all the driven gears can be completely separated from the driving gear, so as to facilitate the adjustment of the meshing amount of the driven gear and the driving gear.

[0019] Optionally, a plurality of racks are slidably provided on the side wall of the machine body along the axial direction of the main shaft, the ends of the racks are abutted against the two ends of the connecting plate, an adjusting cap located on one side of the racks is rotatably connected to the side wall of the machine body, and an adjusting gear meshing with the racks is coaxially connected to the adjusting cap.

[0020] By adopting the above technical solution, when the connecting plate is moved in the direction away from the rear end cover, the adjusting cap is rotated to drive the adjusting gear to rotate, and the adjusting gear rotates to drive the rack to slide toward the rear end cover, so that the rack pushes the connecting plate to move in the direction away from the rear end cover. After the connecting plate pushes the spring to be compressed, it drives part of the tight cap or all of the tight cap to slide in the direction away from the rear end cover. Therefore, by providing the adjusting cap, the adjusting gear and the rack, and utilizing the meshing of the adjusting gear and the rack, the rotation of the adjusting cap can drive the rack to push the connecting plate to move, thereby facilitating the stable movement of the connecting plate between the tight cap and the rear end cover.

[0021] Optionally, a locking rod is slidably penetrated on the adjusting cap, and one end of the locking rod passes through the adjusting cap and is clamped between the teeth of the rack.

[0022] By adopting the above technical solution, when the driven gear and the driving gear are disengaged, the locking rod is pressed toward the adjusting cap, so that the locking rod passes through the adjusting cap and is stuck between the teeth of the rack to limit the rotation of the adjusting gear, thereby limiting the sliding of the rack, thereby facilitating locking the driven gear in a state of being disengaged from the driving gear.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the driving gear and the driven gear, the rotation of the main shaft can drive the rotation of multiple secondary shafts, thereby realizing the rotation of multiple fan blades around the main shaft, so as to increase the heat dissipation range and wind force of the fan blades, thereby improving the heat dissipation effect of the motor in a relatively hot environment;

[0025] 2. By setting the generator coil, magnet and indicator light, the magnet rotates with the secondary shaft, so that the magnetic flux of the generator coil changes, and the indicator light is supplied with current to remind the staff that the motor cooling fan is running normally and dissipating heat, so that the operator can know in time that the motor is working normally;

[0026] 3. By setting a locking cap and a spring, and utilizing the sliding of the countershaft in the bearing seat, the driven gear around the driving gear can be disengaged by pulling part of the locking cap, so as to reduce the energy consumption of the motor in a non-hot environment, thereby achieving the effect of improving the motor driving efficiency;

[0027] 4. By setting up a connecting plate and utilizing the stepped shape of the connecting plate, part of the driven gears can be separated from the driving gears, and all the driven gears can be separated from the driving gears when the connecting plate moves away from the rear end cover, thereby facilitating the adjustment of the meshing amount between the driven gears and the driving gears.

[0028] 5. By setting the adjusting cap, adjusting gear and rack, and utilizing the meshing of the adjusting gear and rack, the rotation of the adjusting cap can drive the rack to move the connecting plate, thereby facilitating the stable movement of the connecting plate between the tight cap and the rear end cover.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses a high heat dissipation motor with an indication function.

[0035] Embodiment 1:

[0036] Reference Figure 1 The high heat dissipation motor includes a body 1, a main shaft 11 rotatably connected to the body 1, and a rear end cover 12 sleeved on one end of the body 1. The rear end cover 12 is provided with a plurality of air inlets 121, and the main shaft 11 passes through both ends of the body 1. One end of the main shaft 11 extending into the rear end cover 12 is coaxially connected to a driving gear 111, and a plurality of secondary shafts 122 are coaxially connected to the end surface of the body 1 located in the rear end cover 12. In the embodiment of the present application, two secondary shafts 122 are selected, and the two secondary shafts 122 are located at the upper and lower ends of the main shaft 11.

[0037] Reference Figure 1 The rotation axis of the secondary shaft 122 is parallel to the rotation axis of the main shaft 11, and the secondary shaft 122 is respectively located at the upper and lower ends of the main shaft 11. The secondary shaft 122 is coaxially connected with a driven gear 123 meshing with the driving gear 111. The diameter of the driving gear 111 is twice the diameter of the driven gear 123, so that the driven gear 123 can be driven to rotate quickly after the driving gear 111 rotates.

[0038] Reference Figure 1 One end of the secondary shaft 122 away from the driven gear 123 is rotatably connected to the inner wall of the rear end cover 12. The rear end cover 12 and the body 1 are both fixed with a bearing seat 13 sleeved on the secondary shaft 122. The secondary shaft 122 is rotatably connected to the body 1 and the rear end cover 12 through the bearing seat 13.

[0039] Reference Figure 1The secondary shaft 122 is coaxially connected with a fan blade 124, which is located between the driven gear 123 and the rear cover 12, and the fan blade 124 is located on both sides of the rotation axis of the main shaft 11. The secondary shaft 122 is located on the rear cover 12, and the bearing seat 13 is sleeved with a magnetic steel 125. The bearing seat 13 on the rear cover 12 is fixed to the generator coil 131, and the generator coil 131 is sleeved outside the magnetic steel 125. The rear cover 12 is fixed with an indicator light 132 electrically connected to the generator coil 131.

[0040] Reference Figure 1 That is, the secondary shaft 122 drives the magnet 125 to rotate in the generating coil 131, so that the magnetic flux in the generating coil 131 changes, thereby generating an induced electromotive force and an induced current to supply power to the indicator light 132, so that the indicator light 132 lights up to prompt the operator that the motor is working normally and dissipating heat normally.

[0041] The implementation principle of Example 1 of the present application is as follows: when the motor is used in a relatively hot environment, the main shaft 11 on the body 1 rotates, the main shaft 11 drives the driving gear 111 to rotate, and the driving gear 111 drives the driven gear 123 to rotate at a multiple speed. This in turn drives the fan blades 124 to rotate rapidly, so that the fan blades 124 on both sides of the main shaft 11 rotate to dissipate heat. While the secondary shaft 122 rotates, it drives the magnet 125 to rotate in the generator coil 131 to generate electricity, so that the indicator light 132 lights up to prompt the operator that the motor is running normally and dissipating heat normally. The rotation of multiple fan blades 124 around the main shaft 11 is achieved to increase the heat dissipation range and wind force of the fan blades 124, thereby improving the heat dissipation effect of the motor in a relatively hot environment.

[0042] Embodiment 2:

[0043] Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that the secondary shaft 122 is located on both sides of the main shaft 11 in the horizontal direction, and only the secondary shaft 122 is inside the bearing seat 13 of the rear end cover 12. The secondary shaft 122 can slide along its own axis in the bearing seat 13, that is, the secondary shaft 122 slides through the rear end cover 12.

[0044] Reference Figure 2 The secondary shaft 122 slides through one end of the rear cover 12 and is rotatably sleeved with a tightening cap 2, and a spring 21 sleeved on the secondary shaft 122 is fixed on the side wall of the tightening cap 2 facing the rear cover 12. A connecting plate 22 is slidably installed between the tightening cap 2 and the rear cover 12, and an avoidance hole for the secondary shaft 122 to slide through is opened on the connecting plate 22, and the end of the spring 21 away from the tightening cap 2 is fixed on the connecting plate 22.

[0045] Reference Figure 2The connecting plate 22 connects the abutting caps 2 on both sides of the axis of the main shaft 11 through the spring 21, and a plurality of guide rods 23 surrounding the spring 21 are fixedly connected to the side wall of the abutting cap 2 facing the rear end cover 12. The guide rods 23 slide through the connecting plate 22 and the rear end cover 12 to guide the sliding of the abutting cap 2.

[0046] Reference Figure 2 and Figure 3 The connecting plate 22 is in a stepped shape, that is, one end of the connecting plate 22 is close to the rear end cover 12, and the other end is far away from the rear end cover 12. The two ends of the connecting plate 22 correspond to two abutting caps 2 respectively, and the sliding friction of the secondary shaft 122 at one end of the connecting plate 22 close to the rear end cover 12 in the bearing seat 13 is small, and the sliding friction of the secondary shaft 122 at one end of the connecting plate 22 far away from the rear end cover 12 in the bearing seat 13 is large.

[0047] When the connecting plate 22 slides in the direction away from the rear end cover 12, the spring 21 at the end of the connecting plate 22 away from the rear end cover 12 compresses and drives the locking cap 2 to slide, so as to disengage the driven gear 123 on one side of the main shaft 11 from the driving gear 111. At this time, the spring 21 at the end of the connecting plate 22 close to the rear end cover 12 is compressed, and does not push the locking cap 2 to drive the driven gear 123 to disengage the driving gear 111. After the connecting plate 22 continues to slide in the direction away from the rear end cover 12, the driven gears 123 on both sides of the main shaft 11 are disengaged from the driving gear 111. After the connecting plate 22 is released, the locking cap 2 is driven to slide towards the rear end cover 12 under the pulling force of the spring 21, so that the driven gear 123 is meshed with the driving gear 111 again.

[0048] Reference Figure 2 and Figure 3 The two sides of the machine body 1 are fixedly connected with a fixing ring 3, and a rack 31 is slidably connected inside the fixing ring 3. The rack 31 slides along the axis direction of the main shaft 11, and the racks 31 on both sides of the machine body 1 are respectively in contact with the two ends of the connecting plate 22. An adjusting cap 32 is rotatably connected to the side wall of the machine body 1 below the rack 31, and an adjusting gear 321 meshing with the rack 31 is coaxially connected to the adjusting cap 32. The adjusting gear 321 is driven to rotate by the rotation of the adjusting cap 32, and then the rack 31 is driven to slide toward the rear end cover 12, so as to push the connecting plate 22 to slide in the direction away from the rear end cover 12, and compress the spring 21 in sequence, so as to facilitate the driven gear 123 to be partially or completely separated from the driving gear 111.

[0049] Reference Figure 2 and Figure 3A locking rod 33 is slidably passed through the adjusting cap 32, and the locking rod 33 slides in a direction perpendicular to the axis of the main shaft 11. The locking rod 33 passes through one end of the adjusting cap 32 and extends between the teeth of the rack 31 to limit the rotation of the adjusting cap 32, limit the rotation of the adjusting gear 321, and further limit the sliding of the rack 31, thereby locking the state of the connecting plate 22 compressing the spring 21.

[0050] The implementation principle of Example 2 of the present application is as follows: when the motor is used in a non-hot environment, the adjusting cap 32 is rotated to drive the adjusting gear 321 to rotate, so that the racks 31 on both sides of the body 1 slide synchronously to push the connecting plate 22 to slide in a direction away from the rear end cover 12, so that the connecting plate 22 first pushes the spring 21 at one end to be compressed, and then pushes one of the locking caps 2 to slide, so as to disengage the driven gear 123 on one side of the main shaft 11 from the driving gear 111.

[0051] Until the rack 31 continues to drive the connecting plate 22 to continue to slide in the direction away from the rear cover 12, so that the end of the connecting plate 22 close to the rear cover 12 also compresses the spring 21, driving the tight cap 2 to move, so that the remaining driven gear 123 and the driving gear 111 are disengaged, thereby achieving partial and complete disengagement of the driven gear 123. In a non-hot environment, the main shaft 11 only drives part of the fan blades 124 to rotate, reducing the energy consumption of the motor and improving the working efficiency of the motor.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
