Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and in particular to an integrated mechanism of motor and gearbox. Background Technology

[0002] In many fields such as industrial automation, machinery and equipment, and transportation, power transmission mechanisms that use drive motors in conjunction with gearboxes are widely used. The core function of this type of mechanism is to use the drive motor to generate initial power, reduce the speed and increase the torque through the gear system inside the gearbox, and finally transmit the adjusted power to the actuator via output components such as shafts. This allows it to meet the specific requirements of different equipment for speed, torque, and spatial layout, making it a key component of modern transmission systems.

[0003] In existing technologies, the drive motor and gearbox are typically designed and manufactured as two independent functional units, requiring assembly and connection in practical applications. Common connection methods include: rigid direct connection via flanges; docking of the two shafts using flexible or rigid couplings; or indirect connection using intermediate transmission components such as belts, synchronous belts, and gear sets. These methods all aim to effectively transmit the rotational motion of the motor shaft to the input shaft of the gearbox, forming a complete transmission chain. Finally, a motor drive structure is required, with power supply and control between the drive motor and gearbox via cables.

[0004] However, the aforementioned split-type layout has several inherent drawbacks. First, it involves a large number of parts, complex installation processes, and the arrangement of various connecting cables further occupies additional space, resulting in a large overall footprint. Furthermore, the split layout requires additional power cables (motor power lines), signal cables (encoder / Hall signal lines), shielded cables, and supporting connectors, terminals, cable trays, corrugated pipes, and other auxiliary materials, further increasing overall wiring costs and space requirements. This further restricts the overall installation layout and increases maintenance costs. These drawbacks limit the application of the transmission system in scenarios requiring compact space, high reliability, and low maintenance costs. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 8 As shown, this utility model embodiment provides an integrated mechanism of motor and gearbox, including a housing 1 and a frameless rotor motor 2, a worm gear transmission pair 3, a gear set 4 and a motor drive plate 5 disposed in the housing 1.

[0031] In this embodiment, the rotor 21 of the frameless rotor motor 2 is coaxially connected to the motor shaft 211. The frameless rotor motor 2 adopts a frameless internal rotor motor structure, with its stator fixedly installed inside the housing 1. The rotor 21 is fitted onto the motor shaft 211 by an interference fit, achieving a coaxial rigid connection between the rotor 21 and the motor shaft 211. This coaxial connection method allows the rotational power of the motor to be directly and efficiently transmitted to the motor shaft 211, avoiding the misalignment problem that may occur between the traditional motor shaft and the gearbox input shaft, thereby ensuring the accuracy and stability of the transmission.

[0032] In the worm gear transmission pair 3, the worm 31 is connected to the motor shaft 211. Specifically, a first synchronous pulley 212 is mounted on the motor shaft 211, and a second synchronous pulley 311 is mounted on the worm 31. The first synchronous pulley 212 and the second synchronous pulley 311 are connected by a synchronous belt 8, forming a synchronous belt transmission mechanism. The motor shaft 211 and the first synchronous pulley 212 are manufactured as a single unit, and the worm 31 and the second synchronous pulley 311 are also manufactured as a single unit. This integrated structure eliminates traditional couplings, flanges, and other connecting parts, significantly reducing the number of parts. When the motor shaft 211 rotates, the first synchronous pulley 212 drives the synchronous belt 8, which in turn drives the second synchronous pulley 311 and the worm 31 integrated with it to rotate, achieving reliable power transmission. Synchronous belt drives have the advantages of accurate transmission ratio, smooth transmission, and low noise, effectively reducing vibration and noise during transmission.

[0033] The gear set 4 includes multiple gears 41 connected in sequence, each gear 41 being integrally connected to a gear shaft 411. The first-stage gear 41 of the multiple gears 41 is connected to the worm wheel 32 in the worm gear transmission pair 3. When the worm 31 rotates, the rotational motion is transmitted to the worm wheel 32 through the meshing of the worm 31 and the worm wheel 32. The worm wheel 32 drives the gear shaft 411 integrally connected to it to rotate, thereby driving the first-stage gear 41 in the gear set 4. The worm gear transmission has the characteristics of large transmission ratio, smooth transmission, and self-locking, and can achieve a large reduction ratio, while also having good vibration reduction and noise reduction effects. The multiple gears 41 in the gear set 4 are sequentially meshed and transmitted through the gear shaft 411, forming a multi-stage gear transmission system, further increasing the reduction ratio and output torque. The end of the gear shaft 411 of the last-stage gear 41 of the multiple gears 41 extends to the outside of the outer casing 1, serving as the power output end of the entire transmission mechanism, transmitting the power after multi-stage reduction and torque amplification to the external actuator.

[0034] The housing 1 contains a drive board mounting cavity 1a and a wiring harness groove 1b connecting the drive board mounting cavity 1a. The motor drive board 5 is mounted in the drive board mounting cavity 1a and is electrically connected to the frameless rotor motor 2 via a wiring harness located in the wiring harness groove 1b. The drive board mounting cavity 1a provides dedicated mounting space for the motor drive board 5, allowing it to be directly integrated into the housing 1, achieving an integrated arrangement of the motor, reducer, and drive board. The wiring harness groove 1b connects the drive board mounting cavity 1a with the space containing the frameless rotor motor 2. The wiring harness is led out from the motor drive board 5 through the wiring harness groove 1b and electrically connected to the frameless rotor motor 2, providing drive power and control signals to the frameless rotor motor 2. This built-in wiring method significantly shortens the cable length between the motor drive board 5 and the frameless rotor motor 2, reduces power loss caused by cable resistance, and improves the overall system efficiency. Simultaneously, the built-in wiring avoids the exposure of external cables, reduces electromagnetic interference, and improves the stability and reliability of signal transmission. In addition, the wiring harness is fixed in the harness groove 1b, which fixes the wiring method and cable length, avoiding problems such as loose or tangled cables, and further improving the reliability of the system.

[0035] The working principle of this embodiment is as follows: When the motor drive board 5 supplies power to the frameless rotor motor 2, the rotor 21 of the frameless rotor motor 2 rotates under the action of electromagnetic force, driving the motor shaft 211 coaxially connected to it to rotate. The first synchronous pulley 212 on the motor shaft 211 rotates accordingly, transmitting power to the second synchronous pulley 311 through the synchronous belt 8, which in turn drives the worm 31 integrated with the second synchronous pulley 311 to rotate. When the worm 31 rotates, it transmits rotational motion and power to the worm wheel 32 through meshing, achieving the first stage of speed reduction. The worm wheel 32 drives the gear shaft 411 and the first-stage gear 41 integrated with it to rotate. The first-stage gear 41 then transmits power sequentially through meshing with the next-stage gear 41 in the gear set 4. Through multi-stage gear transmission, further speed reduction and torque amplification are achieved. Finally, the gear shaft 411 of the last stage gear 41 among the multiple gears 41 outputs the fully reduced and amplified power to the outside of the housing 1, driving the external load to work. Throughout the transmission process, the motor, synchronous belt drive, worm gear drive, and multi-stage gear drive are organically combined to achieve efficient, smooth, and compact power transmission.

[0036] This embodiment integrates the frameless rotor motor 2, worm gear transmission pair 3, gear set 4, and motor drive board 5 into the same housing 1. It also employs an integrated design of the motor shaft 211 and the first synchronous pulley 212, and the worm gear 31 and the second synchronous pulley 311, along with a built-in drive board arrangement and wiring harness connection method. This solves a series of technical problems inherent in the prior art, such as a large number of parts, complex installation process, large overall space occupation, high vibration and noise, difficult installation and maintenance, and high wiring costs, resulting from the separate arrangement of the drive motor and gearbox. This integrated mechanism is compact, operates smoothly, and is easy to install and maintain, meeting the application requirements of transmission systems in compact spaces, high reliability, and low maintenance cost scenarios.

[0037] Furthermore, the frameless rotor motor 2 is horizontally mounted inside the housing 1. Horizontal mounting means that the motor shaft 211 of the frameless rotor motor 2 is arranged vertically, the rotor 21 is located in the middle, and the stator 23 is arranged in a ring around the rotor 21 and coaxial with the motor shaft 211. This mounting method reduces the height dimension of the entire mechanism, which is beneficial for installation in height-constrained spaces. At the same time, the horizontal arrangement facilitates reasonable spatial configuration with the synchronous belt drive mechanism, worm gear transmission pair 3, and gear set 4, allowing each transmission component to be compactly arranged in the horizontal plane, further optimizing the overall structural compactness.

[0038] Furthermore, a magnetic ring 22 is provided at the bottom of the motor shaft 211, and an encoder 6 electrically connected to the wiring harness is provided at the bottom of the housing 1. The encoder 6 is spaced apart from the magnetic ring 22 and connected to the wiring harness in the wiring harness slot 1b. The magnetic ring 22 is installed at the bottom of the motor shaft 211 and rotates with the motor shaft 211. The encoder 6 is fixedly installed on a stationary part at the bottom of the housing 1, maintaining a certain distance from the magnetic ring 22. It obtains the rotational position and speed information of the motor shaft 211 by detecting the change in the magnetic field generated when the magnetic ring 22 rotates. There is no mechanical contact between the encoder 6 and the magnetic ring 22, adopting a non-contact detection method, avoiding mechanical wear, and improving the reliability and service life of the detection. The encoder 6 is electrically connected to the motor drive board 5 through the wiring harness in the wiring harness slot 1b, transmitting the detected position and speed signals to the motor drive board 5. The motor drive board 5 performs precise closed-loop control of the frameless rotor motor 2 based on these feedback signals, realizing precise adjustment of the motor speed and position, and improving the control accuracy and stability of the entire transmission system.

[0039] Furthermore, the bottom of the outer casing 1 is provided with an encoder mounting slot 1c, and the wiring harness slot 1b communicates with the side wall of the encoder mounting slot 1c. An encoder cover plate 7 is detachably covered on the encoder mounting slot 1c, and the encoder 6 is fixedly mounted on the encoder cover plate 7. The encoder mounting slot 1c provides a dedicated installation space for the encoder 6, facilitating the positioning and fixation of the encoder 6. The communication between the wiring harness slot 1b and the side wall of the encoder mounting slot 1c allows the wiring harness leading from the encoder 6 to smoothly connect to the motor drive board 5 through the wiring harness slot 1b, achieving reliable signal transmission. The encoder cover plate 7 is detachably covered on the encoder mounting slot 1c, providing protection for the encoder 6 and preventing dust, oil, and other impurities from entering the encoder mounting slot 1c and affecting the normal operation of the encoder 6. On the other hand, the detachable design of the encoder cover plate 7 facilitates quick opening of the encoder cover plate 7 for operation when maintenance or replacement of the encoder 6 is required, improving the convenience of maintenance. The encoder 6 is fixedly mounted on the encoder cover plate 7. When it is necessary to disassemble the encoder 6, simply remove the encoder cover plate 7 to remove the encoder 6 at the same time, which simplifies the disassembly and assembly process.

[0040] Furthermore, the outer casing 1 includes a detachably connected lower cover 11 and upper cover 12. The lower cover 11 and upper cover 12 are detachably connected by fasteners such as bolts to form a complete outer casing 1. This split upper and lower cover structure facilitates the installation of internal components such as the frameless rotor motor 2, worm gear transmission pair 3, gear set 4, and motor drive board 5 into the lower cover 11 during assembly, and then the upper cover 12 is closed and tightened to complete the assembly of the entire mechanism. When maintenance or repair of internal components is required, only the upper cover 12 needs to be removed to easily access the various internal components without completely disassembling the entire mechanism, greatly improving the convenience and efficiency of maintenance. At the same time, the split design of the lower cover 11 and upper cover 12 also facilitates flexible adjustment of the internal structure or replacement of transmission components of different specifications according to different application requirements.

[0041] Furthermore, the lower cover 11 is provided with a motor mounting slot 111 matching the frameless rotor motor 2, a first gear shaft mounting slot 112 matching the gear set 4, and a worm gear mounting slot 113 located between the motor mounting slot 111 and the first gear shaft mounting slot 112. The upper cover 12 is provided with a first synchronous pulley mounting slot 121 and a second synchronous pulley mounting slot 122 matching the first synchronous pulley 212 and the second synchronous pulley 311, two synchronous belt mounting slots 123 connecting the first synchronous pulley mounting slots 121 and the second synchronous pulley mounting slots 122 from both sides, and a second gear shaft mounting slot 124 matching the gear set 4. The shape and size of the motor mounting slot 111 match the frameless rotor motor 2, facilitating the precise positioning and fixing of the stator of the frameless rotor motor 2 within the lower cover 11. The first gear shaft mounting slot 112 provides support and guidance for the gear shafts 411 of each gear 41 in the gear set 4, ensuring that the gear shafts 411 can rotate smoothly. The worm gear mounting groove 113 is located between the motor mounting groove 111 and the first gear shaft mounting groove 112, and is used to mount the worm gear 31 so that the worm gear 31 can accurately mesh with the worm wheel 32. The first synchronous pulley mounting groove 121 and the second synchronous pulley mounting groove 122 on the upper cover 12 respectively accommodate the first synchronous pulley 212 and the second synchronous pulley 311, providing space for their rotation. The two synchronous belt mounting grooves 123 connect the first synchronous pulley mounting groove 121 and the second synchronous pulley mounting groove 122 from both sides, providing a channel for the tensioning and running of the synchronous belt 8, ensuring that the synchronous belt 8 can be smoothly transmitted between the first synchronous pulley 212 and the second synchronous pulley 311. The second gear shaft mounting groove 124 corresponds to the first gear shaft mounting groove 112 in the lower cover 11, together providing a complete support structure for each gear shaft 411 in the gear set 4. When the lower cover 11 and the upper cover 12 are closed, the first gear shaft mounting groove 112 and the second gear shaft mounting groove 124 form a complete bearing mounting hole, allowing the gear shaft 411 to rotate smoothly under the support of the bearing, ensuring precise meshing between the gears 41. These matching mounting groove structures enable the lower cover 11 and the upper cover 12 to accurately position and fix each transmission component, ensuring the assembly accuracy and operational stability of the entire transmission system.

[0042] Furthermore, the bottom surface of the lower cover 11 has multiple first bolt fixing holes 114 spaced apart along its edge, and the upper cover 12 has multiple second bolt fixing holes 125 correspondingly provided. The first bolt fixing holes 114 and second bolt fixing holes 125 are used to pass bolts through, fastening the lower cover 11 and the upper cover 12 together. The multiple first bolt fixing holes 114 are spaced apart along the edge of the bottom surface of the lower cover 11, ensuring that the fastening force is evenly distributed on the connection surface of the lower cover 11 and the upper cover 12, guaranteeing the sealing and the firmness of the connection. The second bolt fixing holes 125 on the upper cover 12 correspond to the first bolt fixing holes 114. After the lower cover 11 and the upper cover 12 are aligned, the bolts pass through the second bolt fixing holes 125 and the first bolt fixing holes 114 in sequence, and are locked with nuts, thus completing the fastening connection between the lower cover 11 and the upper cover 12. This bolt connection method is simple and reliable, easy to assemble and disassemble, and allows for quick opening or closing of the outer casing 1 when needed.

[0043] Furthermore, the gear shaft 411 of the last stage gear 41 in the plurality of gears 41 extends out from both sides to the outside of the housing 1. This dual-end output structure design allows both ends of the gear shaft 411 to serve as power output ends, enabling the simultaneous driving of two external actuators, or one end to be used for power output while the other end is used to connect to other auxiliary equipment, such as brakes or speed measuring devices, thereby improving the application flexibility and functional expandability of this integrated mechanism. At the same time, the dual-end output structure also helps to balance the forces on the gear shaft 411, reduce the bending deformation of the gear shaft 411, and improve the stability and reliability of the transmission.

[0044] Furthermore, the outer casing 1 is provided with a communication interface 13 that is electrically connected to the motor drive board 5. The communication interface 13 is installed on the outer surface of the outer casing 1 and is electrically connected to the internal motor drive board 5 via an internal wiring harness. The communication interface 13 is used to connect the motor drive board 5 to external upper-level control devices such as industrial control computers and PLCs, enabling the upper-level control devices to issue control commands to the motor drive board 5 and the motor drive board 5 to feed back operating status, fault information, and other data to the upper-level control devices. Through the communication interface 13, the entire integrated mechanism can be easily remotely controlled and monitored, achieving intelligent management. The setting of the communication interface 13 avoids the inconvenience of having to open the outer casing 1 to connect control cables, improving the convenience of operation, while also ensuring the airtightness of the outer casing 1, preventing dust, oil, and other impurities from entering the interior and affecting the normal operation of the motor drive board 5 and other components.

[0045] The integrated motor and gearbox mechanism provided in this embodiment achieves integration of the motor, gearbox, and drive board through the integrated design of frameless rotor motor, synchronous belt drive, worm gear drive, multi-stage gear drive, and built-in motor drive board. It boasts significant advantages such as compact structure, smooth operation, low vibration and noise, convenient installation and maintenance, high transmission efficiency, and strong reliability. The entire mechanism has fewer parts, a simple assembly process, requires no on-site alignment and debugging, and has a short installation cycle. The built-in wiring method shortens cable length, reduces power loss, improves system efficiency, and avoids electromagnetic interference, enhancing signal transmission stability. The motor drive board is housed in a sealed casing, completely isolating it from dust, oil, moisture, and vibration, significantly improving system reliability. Its small size and light weight make it particularly suitable for applications requiring compact space, high reliability, and low maintenance costs, such as industrial robots, automated production lines, and vehicle-mounted equipment.
