Description

Technical Field

[0001] The present invention relates to the technical field of motor equipment, and in particular to a series synchronous dual-motor transmission component. Background Art

[0002] In space-constrained usage scenarios (such as robot joints, portable power tools, etc.), it is impossible to install a single large-sized motor. In order to meet the driving load requirements, two smaller motors of the same power will be used to jointly drive the output shaft through a transmission mechanism to meet the high-load driving requirements in the narrow space of engineering applications.

[0003] However, there are the following problems in the use of two motors:

[0004] When one of the motors stops due to mechanical jamming (such as foreign matter stuck in the gearbox, friction between the rotor and stator), winding short circuit (insulation aging or overvoltage breakdown), or bearing damage (lubrication failure causing ball bearing jamming), the rigidly connected transmission mechanism will put the healthy motor in the dilemma of "reverse driving the faulty motor": the rotor of the faulty motor is equivalent to forming a fixed resistance on the output shaft. The healthy motor must simultaneously bear the rated load torque and the static friction torque of the faulty motor, causing its armature current to rise sharply to several times the rated value. In the lithium battery power supply system of portable tools, this overload current may cause the battery protection board to urgently cut off the power supply. In the servo drive system of the robot joint, even if the driver has a short-term overload capacity, the motor winding will overheat within tens of seconds due to the surge in copper loss, carbonizing and emitting smoke from the insulating paint, eventually leading to demagnetization of the permanent magnet or burning of the coil, which in turn paralyzes the entire drive system.

[0005] In the prior art, to implement fault alarms, it is usually necessary to install an electronic monitoring module on the motor to identify abnormal conditions. The overall detection cost is high, and it is difficult to detect motor locking faults in a timely and economical manner. Summary of the Invention

[0006] In order to overcome the above technical problems, the purpose of the present invention is to provide a series synchronous dual-motor transmission component to solve the problem raised in the above background technology that a single motor stops due to mechanical jamming, winding short circuit and other faults, resulting in the overload and burning of the healthy motor.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a series synchronous dual-motor transmission component, comprising a main shaft body, wherein the main shaft body is fixedly connected to two sets of main gears, and each side of the two sets of main gears is provided with a set of main motors, and the two sets of main motor circuits are connected in series, wherein the following technical solution is also provided:

[0008] A centrifugal self-breaking linkage mechanism is connected between the main motor and the main gear, and is used to transmit power to the main gear and the main shaft body when the main motor is working normally, and to disconnect power transmission when the main motor fails and locks; the centrifugal self-breaking linkage mechanism includes a centrifugal shaft assembly, a clutch assembly and a transmission assembly; the centrifugal shaft assembly includes a central shaft 1 and a central shaft 2 fixedly connected to the working end of the main motor, the central shaft 1 is fixedly connected to the guide sleeve through a groove, the outer wall of the guide sleeve is rotatably connected to the adjustment ring, and the adjustment ring is slidably engaged with the guide frame through a spiral protrusion; the centrifugal self-breaking linkage mechanism also includes a warning assembly, including a protruding rod fixed to the outer oblique block and a bell component group on the side of the cylinder shell. When a fault occurs, the protruding rod collides with the rotating bell component group to trigger an alarm.

[0009] Preferably, the guide frame is internally slidably connected to the centrifugal bevel block, and a tension spring is provided between the centrifugal bevel block and the guide frame; the clutch assembly comprises an outer bevel block, a dynamic clutch plate and a static clutch plate, the outer bevel block is slidably connected to the cylindrical shell of the transmission assembly, the dynamic clutch plate is fixed to the outer bevel block, and the static clutch plate is fixed to the cylindrical shell; the centrifugal bevel block contacts the outer bevel block through the inclined surface, and the centrifugal force drives the centrifugal bevel block to push the outer bevel block to move axially, so that the dynamic clutch plate and the static clutch plate are frictionally engaged; the outer wall of the cylindrical shell of the transmission assembly is fixed with a gear ring, and the gear ring engages with the main gear.

[0010] Preferably, the guide frame moves radially in the sliding groove of the guide sleeve through the spiral protrusion, and the guide frame is used to adjust the initial distance between the centrifugal inclined block and the outer inclined block.

[0011] Preferably, an anti-slip ring is provided on the outer wall of the adjustment ring, and is locked in position by a limiting plate and a screw, and the limiting plate is fixedly connected to the guide sleeve.

[0012] Preferably, the contact surface between the centrifugal inclined block and the outer inclined block is an inclined surface with an inclination angle of 15°, and the outer inclined block is pushed to move axially under the action of centrifugal force.

[0013] Preferably, a tension spring is provided between the outer bevel block and the cylinder shell for resetting the outer bevel block and the movable clutch plate in case of failure.

[0014] Preferably, the cylinder shell is rotatably connected to the second central axis via a cylinder frame, the cylinder frame is fixedly connected to a mounting frame, and the mounting frame rotatably supports the first central axis and the second central axis.

[0015] Preferably, the bell component group of the warning assembly includes a metal bell and a spring connected to the cylindrical shell, and a metal impact head is provided at the end of the protruding rod. When a fault occurs, the cylindrical shell rotates and collides with the stationary protruding rod periodically to produce a sound.

[0016] Preferably, the friction surfaces of the dynamic clutch plate and the static clutch plate are coated with a tungsten carbide wear-resistant layer, and an anti-slip limit block is provided in the guide frame to limit the maximum displacement of the centrifugal bevel block and prevent the centrifugal bevel block from detaching from the guide frame.

[0017] Preferably, the centrifugal shaft assembly, clutch assembly and transmission assembly are two symmetrically distributed groups, which are respectively connected to two main motors and independently respond to faults and trigger disconnection.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When a main motor stops due to mechanical jamming, winding short circuit, or bearing damage, the centrifugal self-disconnect mechanism retracts the centrifugal wedge and resets the tension spring, driving the dynamic and static clutch plates to quickly separate, completely severing the power transmission path between the faulty motor and the main gear. This purely mechanical disconnection mechanism prevents the healthy motor from being forced to reverse drive the faulty motor, eliminating the risk of overload current and temperature rise, and ensuring that the healthy motor always operates safely within the rated load.

[0020] 2. Through the mechanical collision design between the protruding rod and the bell assembly, when a faulty motor is disconnected, the rotating cylinder drives the bell assembly to periodically collide with the stationary protruding rod, generating an alarm. This structure requires no electronic sensors, controllers, or external power supply, significantly reducing system costs. It also maintains 100% alarm reliability in dusty, high-temperature, and vibration environments, completely resolving the issues of traditional electronic monitoring modules being prone to failure and complex maintenance.

[0021] 3. By rotating the adjustment ring, the guide frame moves radially, precisely adjusting the initial spacing between the centrifugal and outer bevel blocks, thereby linearly varying the speed threshold required to trigger clutch engagement. This design allows users to customize the triggering conditions based on load characteristics (e.g., low speed, high torque, or high speed, low torque), breaking through the limitations of traditional centrifugal clutches with fixed thresholds and significantly expanding the application scenarios of the equipment.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] An embodiment provided by the present invention:

[0033] refer to Figure 1 and Figure 2 A series synchronous dual-motor transmission component includes a main shaft body 11, two sets of main gears 12 are fixedly connected to the main shaft body 11, and a set of main motors 13 are provided on the side of each set of main gears 12. The two sets of main motors 13 are connected in series circuits and are controlled by a controller to simultaneously operate the two sets of main motors 13, wherein the following is also included:

[0034] The centrifugal self-breaking linkage mechanism is used to connect between the main motor 13 and the main gear 12 to start the transmission function. When the main motor 13 is working, the power is output to the main gear 12 and the main shaft body 11 through the centrifugal self-breaking linkage mechanism. When the main motor 13 fails and locks, the centrifugal self-breaking linkage mechanism disconnects the connection between the main motor 13 and the main gear 12 to prevent the other main motor 13 from reversely driving the locked main motor 13 through the main shaft body 11 and the main gear 12 when the other main motor 13 is working normally.

[0035] refer to Figure 2 and Figure 3 The centrifugal self-breaking linkage mechanism includes a centrifugal shaft assembly 02, a clutch assembly 03 and a transmission assembly 04;

[0036] refer to Figure 2 and Figure 3, the centrifugal shaft assembly 02 is used to rotate with the working end of the main motor 13, the centrifugal shaft assembly 02 includes a central axis 21, one end of the central axis 21 is fixedly connected to the central axis 22, and the end of the central axis 22 away from the central axis 21 is fixedly connected to the working end of the main motor 13, the central axis 21 is fixedly connected to the guide sleeve 23 through a groove, the central axis 21 and the central axis 2 22 are on the same axis, the outer wall of the guide sleeve 23 is rotatably connected with an adjusting ring 24, the adjusting ring 24, the guide sleeve 23, the central axis 21 and the central axis 2 22 are on the same axis, a limiting plate 25 is provided on the side of the adjusting ring 24, the limiting plate 25 is provided with a screw through a hole, the adjusting ring 24 is provided with multiple groups of threaded holes corresponding to the screws, the adjusting ring 24 is connected to the limiting plate 25 by screws, and the limiting plate 25 is fixedly connected to the guide sleeve 23.

[0037] refer to Figure 3-Figure 6 The guide sleeve 23 is in sliding contact with a guide frame 26, and a spiral protrusion is provided on the side of the adjusting ring 24, and the guide frame 26 contacts the adjusting ring 24 through the spiral protrusion. The outer wall of the adjusting ring 24 is connected with an anti-slip ring. When removing the screws on the limit plate 25, by holding the anti-slip ring and rotating the adjusting ring 24, the adjusting ring 24 is rotatably connected to the guide sleeve 23, so that the spiral protrusion on the side of the adjusting ring 24 can drive the guide frame 26 to make radial displacement in the slide groove of the guide sleeve 23. Figure 3 The guide frame 26 can move upward or downward. The guide frame 26 is in sliding contact with a centrifugal inclined block 27. A tension spring is connected between the centrifugal inclined block 27 and the guide frame 26. The guide frame 26 is provided with an anti-slip limit block corresponding to the centrifugal inclined block 27, which is mainly used to prevent the centrifugal inclined block 27 from slipping out of the guide frame 26. The specific structure of the guide sleeve 23 is shown in FIG. Figure 5 As shown, the relationship between the guide frame 26 and the adjustment ring 24 is shown in FIG. Figure 6 As shown, when the adjusting ring 24 is rotated, the guide frame 26 can move radially through the guidance of the threaded protrusion and the guide sleeve 23. This movement mainly adjusts the distance between the guide frame 26 and the outer bevel block 31, thereby adjusting the speed required for the centrifugal bevel block 27 to contact the outer bevel block 31. After adjusting the position of the guide frame 26, the position of the guide frame 26 can be locked by connecting the limit plate 25 and the adjusting ring 24 with screws.

[0038] refer to Figure 3The clutch assembly 03 includes an outer bevel block 31, a dynamic clutch plate 32, an outer ring 34 and a static clutch plate 33. A tension spring is provided between the inner wall of the outer bevel block 31 and the outer ring 34, wherein the outer bevel block 31 slides in contact with the inner wall of the cylinder shell 41, the outer bevel block 31 is fixedly connected to the dynamic clutch plate 32, and the static clutch plate 33 is fixedly connected to the cylinder shell 41 through a groove, and the outer ring 34 is rotatably connected to the cylinder shell 41, wherein a connecting bracket is provided between the outer ring 34 and the guide sleeve 23, and the outer ring 34 will rotate with the guide sleeve 23. Under the action of centrifugal force, the centrifugal bevel block 27 will be thrown out to contact the outer bevel block 31, and the centrifugal bevel block 27 and the outer bevel block 31 are in contact through the inclined surface. Under the action of centrifugal force, the centrifugal bevel block 27 will apply a thrust to the outer bevel block 31, and the thrust bearing position is the inclined surface between the two, and then the outer bevel block 31 will move along the axis toward the static clutch plate 33 under the pushing action, that is, Figure 3 The outer bevel block 31 drives the dynamic clutch plate 32 to move to the left together. At this time, the dynamic clutch plate 32 rotates and moves toward the static clutch plate 33, while the static clutch plate 33 is stationary. The dynamic clutch plate 32 will frictionally contact the static clutch plate 33. At this time, the tension spring between the outer bevel block 31 and the cylinder shell 41 accumulates force and stretches.

[0039] When the main motor 13 rotates to a certain speed, the transmission assembly 04 is driven to rotate through the centrifugal shaft assembly 02 and the clutch assembly 03. The transmission assembly 04 includes a cylinder shell 41. The outer wall of the cylinder shell 41 is fixedly connected with a ring gear 42 and a cylinder frame 43. The ring gear 42 engages the main gear 12. The cylinder frame 43 is rotatably connected to the cylinder shell 41. The cylinder frame 43 is used to stabilize the position of the cylinder shell 41. The cylinder shell 41 is also rotatably connected to the middle shaft 22.

[0040] refer to Figure 2 and Figure 7 , warning component 05, which is used to sound a bell alarm by mechanically cooperating with the clutch component 03 when the main motor 13 fails. The warning component 05 includes a protruding rod 51 and a bell component group 52. The protruding rod 51 slides in contact with the outer ring 34 through the hole. One end of the protruding rod 51 is fixedly connected to the outer bevel block 31. The other end of the protruding rod 51 is provided with a metal impact head. When one of the two groups of main motors 13 fails, this group of main motors 13 is locked due to damage, and the centrifugal bevel block 27 cannot be thrown out under the centrifugal force. The tension spring between the centrifugal bevel block 27 and the guide frame 26 will pull the centrifugal bevel block 27 back into the guide frame 26 slide groove, and the centrifugal bevel block 27 will break away from the contact with the outer bevel block 31. The tension spring between the outer bevel block 31 and the cylinder shell 41 will also pull back the outer bevel block 31, and the outer bevel block 31 will move to the right ( Figure 3 ), driving the protruding rod 51 to move together, the bell component group 52 is composed of a metal bell and a spring, and the spring is connected between the metal bell and the cylinder shell 41.

[0041] When one set of main motors 13 fails, the other set of normal main motors 13 will still drive the main shaft 11 and the main gear 12 to rotate, and the cylinder shell 41 will also keep rotating. The bell component group 52 connected to the side of the cylinder shell 41 will contact and collide with the stationary protruding rod 51, and the bell component group 52 will produce a sound to alert the staff within the range that an unexpected failure of the main motor 13 has occurred here and maintenance is required.

[0042] Two groups of mounting frames 06 are provided outside the central axis 1 21 . The two groups of mounting frames 06 are fixedly connected to the cartridge frame 43 . One group of mounting frames 06 is rotatably connected to the central axis 1 21 , and the other group of mounting frames 06 is rotatably connected to the central axis 2 22 . The two groups of mounting frames 06 and the cartridge frame 43 both play an auxiliary role in supporting and installing the overall mechanism.

[0043] Working principle:

[0044] The present invention provides a series synchronous dual-motor transmission component, which realizes the coordinated driving and automatic fault isolation of the dual motors through a centrifugal self-breaking linkage mechanism.

[0045] Coordinated drive of dual motors:

[0046] When the two main motors 13 start normally and reach the set speed, the centrifugal shaft assembly 02 rotates with the motor working end. Centrifugal force causes the centrifugal bevel 27 of the centrifugal shaft assembly 02 to overcome the resistance of the tension spring and be flung outward along the chute of the guide frame 26. The inclined surface of the centrifugal bevel 27 contacts the inclined surface of the outer bevel 31, exerting axial thrust on the outer bevel 31, pushing the outer bevel 31 and the dynamic clutch plate 32 toward the static clutch plate 33.

[0047] As the dynamic clutch plate 32 moves axially, it gradually compresses the static clutch plate 33 (which is fixed within the cylindrical housing 41), forming a friction pair. At this point, the dynamic clutch plate 32 and the static clutch plate 33 transmit torque through friction, causing the cylindrical housing 41 to rotate with the motor speed. The ring gear 42 on the outer wall of the cylindrical housing 41 meshes with the main gear 12, transmitting power to the main shaft 11, driving the load.

[0048] Before use, rotate the adjustment ring 24. The spiral protrusion on its side drives the guide frame 26 to move radially within the guide sleeve 23's slot, thereby changing the initial spacing between the centrifugal bevel 27 and the outer bevel 31. A smaller spacing reduces the centrifugal force required to trigger clutch engagement (i.e., the required speed). A larger spacing requires a higher speed to trigger engagement. Once adjustment is complete, secure the adjustment ring 24 with the stop plate 25 and screws to lock the guide frame 26 in place.

[0049] If one of the main motors 13 stops due to mechanical jamming or electrical failure, the speed of the corresponding centrifugal shaft assembly 02 drops sharply. The centrifugal force of the centrifugal inclined block 27 disappears, and the centrifugal inclined block 27 retracts into the chute of the guide frame 26 under the action of the tension spring, breaking away from contact with the outer inclined block 31.

[0050] Automatic fault isolation:

[0051] The main motor 13 locks, and the centrifugal bevel 27 is pulled back into the guide frame 26 by the tension spring. The tension spring between the outer bevel 31 and the cylindrical shell 41 quickly pulls the outer bevel 31 back to its initial position, causing the dynamic clutch plate 32 to move rightward and completely disengage from the static clutch plate 33. At this point, the power transmission path of the faulty main motor 13 is physically cut off, preventing the healthy main motor 13 from reversely driving the faulty motor through the main shaft 11, thus preventing overload.

[0052] alarm:

[0053] When the outer bevel block 31 moves rightward, it drives the cam 51 to move synchronously. Since the outer bevel block 31 of the faulty motor stops rotating, while the cylinder shell 41 is still rotated by the main gear 12, the bell assembly 52 on the side of the cylinder shell 41 periodically collides with the metal impact head on the stationary cam 51, generating a continuous bell alarm, prompting personnel to promptly carry out maintenance.

[0054] It should be noted that due to the characteristics of the structural design, the warning bell will also produce a bell sound when the main motor 13 does not rotate at an adequate speed in the initial stage. However, when the speed is sufficient for the cylinder shell 41 to be driven, the protruding rod 51 and the bell component assembly 52 rotate at the same speed and no collision occurs, and thus no bell sound will be produced.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
