[0039] like Figure 1-5As shown, a high-torque compact joint module includes a housing assembly 1, a reduction mechanism 2, a motor 3, a sealing assembly 4, and a drive assembly 5. The reduction mechanism 2, motor 3, sealing assembly 4, and drive assembly 5 are fixedly connected within the housing assembly 1. The housing assembly 1 includes a bearing assembly 101, a front cover 103, a reduction mechanism housing 104, a motor housing 105, a drive fixing component 106, a rear cover 107, a rotor frame 108, and a fastening assembly. The reduction mechanism 2 includes a primary reduction mechanism 21 and a secondary reduction mechanism 22. The sealing assembly 4 includes a first seal 41, and the fastening assembly includes a first fastener 1091. The primary reduction mechanism 21 and the secondary reduction mechanism 22 are coaxially connected. The primary reduction mechanism 21 is the power input end, and the secondary reduction mechanism 22 is the power output end. The speed reduction mechanism 21 is fixedly connected to the rotor frame 108; the secondary speed reduction mechanism 22 is fixedly connected to the bearing assembly 101; the outer periphery of the speed reduction mechanism 2 is covered by the speed reduction mechanism housing 104, and the outer circumference of the secondary speed reduction mechanism 22 is provided with an arc groove, and the first fastener 1091 passes through the arc groove to connect the speed reduction mechanism 2 to the speed reduction mechanism housing 104; the first fastener 1091 is a threadless fastener with a T-shaped cross section; the rotor frame 108 is connected to the motor 3, the outer periphery of the motor 3 is covered by the motor housing 105, and the outer periphery of the bearing assembly 101 is covered by the front cover 103; the rear cover 107, the drive fixing member 106, the motor housing 105, the speed reduction mechanism housing 104 and the front cover 103 are connected in sequence; the drive fixing member 106 is provided with a clearance structure 1061, and the clearance structure 1061 accommodates the first sealing member 41.
[0040] A high-torque compact joint module is powered by a motor 3, which outputs rotational motion at a certain speed and torque through the rotation of its rotor. A drive board receives signals and precisely controls the motor 3's start, stop, speed adjustment, and direction of movement, enabling the motor 3 to operate according to the desired motion requirements. This, in conjunction with a reduction mechanism 2, drives the entire joint module to complete corresponding actions, achieving precise control over joint angle, speed, and direction to meet complex and diverse automated operation needs. The reduction mechanism 2, after conversion, reduces the speed transmitted from the motor 3, transforming the high-speed, low-torque motion into a low-speed, high-torque motion based on its reduction ratio, thus outputting suitable high torque to the joint module. The reduction mechanism 2, motor 3, sealing assembly 4, and drive assembly 5 are fixedly connected within a housing assembly 1. Sealing assemblies 4 are provided at the connection points between any two of the bearing assembly 101, front cover 103, reduction mechanism housing 104, motor housing 105, drive fixing component 106, rear cover 107, and rotor frame 108.
[0041] Among them, such as Figure 4As shown, the reduction mechanism 2 is a two-stage reduction mechanism. The two-stage reduction mechanism can effectively increase the output torque through two-stage transmission, thereby better meeting the demand for high torque; it can achieve a large transmission ratio and torque output in a relatively small space, making the whole mechanism more compact. During the transmission process, the transmission components in the two-stage reduction mechanism can play a role in buffering and shock absorption, reducing the impact and vibration during power transmission.
[0042] Among them, such as Figure 2 and 3 As shown, the sealing assembly 4 includes a static seal and a dynamic seal. The static seal is used to seal between two relatively stationary surfaces, preventing internal media from leaking out or external impurities from entering. The dynamic seal is used to seal between two surfaces with relative movement, allowing this movement to proceed smoothly while ensuring a good seal. The first seal 41 is a static seal. The static and dynamic seals significantly improve the sealing performance of the joint module, effectively preventing water and dust from entering the joint module, thereby improving the durability and reliability of the joint module.
[0043] In this embodiment, as Figure 2 and 3 As shown, the first-stage reduction mechanism 21 and the second-stage reduction mechanism 22 are coaxially connected. The outer circumference of the second-stage reduction mechanism 22 is provided with an arc groove, which provides guidance for the first fastener 1091. The first fastener 1091 passes through the arc groove to connect the second-stage reduction mechanism 22 to the reduction mechanism housing 104, thereby restricting the axial and radial movement of the reduction mechanism 2. The end face of the reduction mechanism housing 104 abuts against the end face of the motor housing 105, further restricting the axial movement of the first fastener 1091. This connection method between the secondary reduction mechanism 22 and the reduction mechanism housing 104 has several advantages. First, by placing the connection point on the circumferential surface of the secondary reduction mechanism 22 rather than its end face, the drilling process on the end face of the secondary reduction mechanism is reduced, thus effectively lowering costs. Second, since the secondary reduction mechanism 22 can tightly abut against the end face of the motor housing 105, the axial movement of the first fastener 1091 is restricted. Therefore, the first fastener 1091 can adopt a threadless structure, which not only reduces the processing cost of the first fastener 1091, but also shortens the overall size of the first fastener 1091 by removing the threaded part, making the internal space of the housing assembly 1 more compact. Consequently, the size of the joint module can be shortened, which helps to reduce the overall size of the machine and reduce manufacturing costs. In addition, this connection method also allows the first fastener 1091 to be easily installed or removed without rotation, eliminating the need for tools such as screwdrivers and wrenches, further saving time and labor costs.
[0044] In this embodiment, as Figure 2 and 3As shown, the drive fixing member 106 is connected to the motor housing 105. The drive fixing member 106 is provided with a clearance structure 1061, which allows the first sealing member 41 to be tightly attached to the motor housing 105. The first sealing member 41 is accommodated in the clearance structure 1061 and deforms in the direction of the drive fixing member 106. In addition, the clearance structure 1061 improves the guiding effect of the drive fixing member 106 on the motor housing 105, making installation more convenient.
[0045] A high-torque compact joint module, through the design of the first fastener 1091 and the clearance structure 1061, achieves coaxial positioning and a housing that is easy to assemble and disassemble, which simplifies the installation and maintenance process of the joint module, reduces the manufacturing cost of the joint module, and is beneficial to the maintenance and upgrading of the joint module.
[0046] In this embodiment, as Figure 2 and 3 As shown, the clearance structure 1061 is further defined: the drive fixing member 106 has an annular groove on the circumferential surface of the end connected to the motor housing 105, and the annular groove is the clearance structure 1061. Specifically, the annular groove is provided on the circumferential surface of the drive fixing member 106 at the end connected to the motor housing 105. In the prior art, referring to... Figure 3 The motor housing 105 shown has a through hole 1052 on its circumference. When conventional housing parts are connected to the motor housing 105, the seal passes through and contacts the hole during assembly, which can cause wear and compression on the seal. However, the drive fixing component 106 in this design has a clearance structure. During connection, the first seal 41 avoids the hole surface and is accommodated and fixed in the annular groove. After compression, it contacts the circumferential surface of the drive fixing component 106, achieving a sealing effect while avoiding damage to the first seal 41, thus reducing the production and maintenance costs of the joint module.
[0047] In this embodiment, as Figure 5 As shown, motor 3 is an internal rotor frameless torque motor 3, which includes a motor rotor 31 and a motor stator 32 connected to each other; the motor rotor 31 is fixedly connected to the rotor frame 108. Specifically, the motor rotor 31 is a rotating part, and power is output through the motor rotor 31; the motor rotor 31 is fixedly connected to the rotor frame 108 so that the power generated by the motor 3 is output to the reduction mechanism 2.
[0048] In this embodiment, as Figure 2 and 3As shown, the drive assembly 5 includes a first drive plate 51, a first sensing element 52, a second drive plate 53, and a second sensing element 54. The first sensing element 52 is fixedly connected to the rotor frame 108, and the second sensing element 54 is fixedly connected to the secondary reduction mechanism 22. The first drive plate 51 is fixedly connected to the drive fixing member 106, and the second drive plate 53 is fixedly connected to the motor housing 105. The first drive plate 51 reads the signal from the first sensing element 52, and the second drive plate 53 reads the signal from the second sensing element 54. The first drive plate 51 is electrically connected to the motor 3, and the first drive plate 51 is electrically connected to the second drive plate 53. Specifically, the first drive plate 51, the first sensing element 52, the second drive plate 53, and the second sensing element 54 work together to realize the position detection and control of the input and output ends of the entire machine. The first sensing element 52 monitors the operating status of the input end of the reduction mechanism 2, and the second sensing element 54 monitors the operating status of the output end of the reduction mechanism 2 in real time. The operating status includes key parameters such as speed and direction of rotation, thereby ensuring the precise control and stable operation of the entire transmission system. The first drive board 51 is fixedly connected to the drive fixing member 106, receives and processes signals from the first sensing element 52, and the first drive board 51 communicates with the second drive board 53 through electrical connection; the second drive board 53 is fixedly connected to the motor housing 105, receives and processes signals from the second sensing element 54, so that the first drive board 51 and the second drive board 53 realize global monitoring and coordinated control of the entire drive system.
[0049] In this embodiment, as Figure 2 and 3 As shown, the housing assembly 1 also includes a bearing pressure plate 102, which is disposed between the bearing assembly 101 and the front cover 103. The sealing assembly 4 also includes a dynamic second seal 42, which is disposed between the bearing pressure plate 102 and the front cover 103. Specifically, the bearing pressure plate 102 is provided to further fix the bearing assembly 101, making the joint module structure more compact. The second seal 42 is a dynamic seal.
[0050] In this embodiment, as Figure 2 and 3 As shown, the fastening assembly also includes several second fasteners 1092, which connect the front cover 103 and the reduction mechanism housing 104, the reduction mechanism housing 104 and the motor housing 105, the motor 3 and the drive fixing member 106, and the drive fixing member 106 and the rear cover 107. Specifically, in this embodiment, the parts of the housing assembly 1 are connected by several conventional fasteners.
[0051] In one embodiment, such as Figure 2 and 3As shown, the motor housing 105 is provided with a first heat dissipation structure 1051, and the rear cover 107 is provided with a second heat dissipation structure 1071. The first heat dissipation structure 1051 includes a plurality of first grooves, which are equally spaced on the circumferential surface of the motor housing 105; the second heat dissipation structure 1071 includes a plurality of second grooves, which are equally spaced on the end face of the rear cover 107. Specifically, in high-load operation, the motor 3 and the reduction mechanism 2 easily generate a large amount of heat, and insufficient heat dissipation design will damage the performance of the robot joint and shorten its service life. Conventional joint modules add heat dissipation structures inside, but the heat is still difficult to dissipate. This embodiment increases the surface area of the motor housing 105 and the rear cover 107 through the design of the groove structure, thereby significantly increasing their heat dissipation area. By increasing the contact area between the parts and the surrounding environment, heat exchange can be carried out more effectively, thereby improving heat dissipation efficiency. Good heat dissipation performance helps to improve the stability of the joint module and extend its service life, ensuring that the equipment operates at the efficiency of the joint module and reducing energy consumption.
[0052] In one embodiment, wiring channels are provided in the front cover 103, the deceleration mechanism housing 104, the motor housing 105, the drive fixing member 106, and the rear cover 107, which realizes the internal wiring of the control circuit, avoids external wiring, simplifies the wiring of the electrical control system, and improves the convenience of maintenance.
[0053] In one embodiment, the present embodiment adopts a waterproof terminal design for incoming and outgoing lines, which improves the flexibility of cable management and waterproof performance.
[0054] In summary, a high-torque compact joint module and robot integrates the reduction mechanism 2, motor 3, and drive system into a single unit with a more compact design. This achieves miniaturization of the joint module's size and lightness, while enhancing maintainability, effectively reducing manufacturing costs, and significantly improving heat dissipation efficiency. This design solves the technical challenges commonly found in current joint modules, such as large size, excessive weight, high manufacturing costs, low assembly and maintenance efficiency, and insufficient heat dissipation performance.
