Description

Technical Field

[0001] This utility model relates to the field of coupling technology, specifically to a motor coupling structure. Background Technology

[0002] Existing couplings include rigid couplings, flexible couplings, and universal couplings. When used in small devices, these couplings tend to be bulky or heavy. For example, in portable handheld vacuum cleaners where motor power density reaches 0.5W / g, traditional couplings account for over 10% of the weight. Traditional couplings fail to meet the upgrade requirements of consumer-grade devices in terms of lightweighting, quiet operation, and low cost. Therefore, a new coupling structure is needed to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a motor coupling structure that is easy to use and solves the problem that traditional couplings cannot meet the upgrade requirements of consumer-grade equipment in terms of lightweight, quiet operation and low cost.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a motor coupling structure, including two mounting mechanisms, with a transmission mechanism mounted on one end of each mounting mechanism;

[0005] The transmission mechanism includes a mounting sleeve, one end of which is fixedly connected to a mounting base. One end of the mounting base has a groove, and a mounting bolt is mounted on the mounting base. The bottom of the mounting bolt passes through the groove and extends to the bottom of the mounting base. A mounting nut is threaded onto the bottom of the mounting bolt.

[0006] As a preferred embodiment of the motor coupling structure of this utility model, a locking block is installed on the front side of the mounting sleeve, and a fastening bolt is threadedly connected to the locking block and the mounting sleeve.

[0007] In a preferred embodiment of the motor coupling structure of this utility model, the transmission mechanism is located within the groove and is fitted onto the surface of the mounting bolt.

[0008] As a preferred embodiment of the motor coupling structure of this utility model, the mounting bolt has a fixing part on its surface that cooperates with the transmission mechanism, and the groove surface is fixedly connected to the inner wall of the fixing part.

[0009] As a preferred embodiment of the motor coupling structure of this utility model, a first motor is mounted on one mounting mechanism, a first transmission shaft is mounted on another mounting mechanism, a load is mounted on the output end of the first transmission shaft, and a second transmission shaft is mounted on the output end of the load.

[0010] As a preferred embodiment of the motor coupling structure of this utility model, it further includes a second motor, the output shaft of the second motor is sleeved with a first transmission wheel, the surface of the first transmission shaft is sleeved with a second transmission wheel, and the surfaces of the first transmission wheel and the second transmission wheel are connected by a transmission belt.

[0011] In a preferred embodiment of the motor coupling structure of this utility model, the mounting sleeve and the locking block are fitted onto the output shaft of the first motor and the input end of the first transmission shaft, and the fastening bolts secure the locking block and the mounting sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The first motor of this utility model clamps the output shaft through the mounting sleeve and the clamping block. The torque is transmitted to the first transmission shaft through the transmission component to drive the load to work. The annular deoxygenated polymer material of the transmission component compensates for the installation error through shear deformation. At the same time, the internal steel wire and carbon fiber rope are used to enhance the tensile strength. The second motor works in conjunction with the first transmission shaft through the transmission belt to form dual power redundancy. In the low speed and high torque working condition, the main motor drives independently. In the high speed and light load working condition, the second motor accelerates synchronously.

[0014] 2. The transmission component of this utility model is made of delexicon polymer material. When subjected to load, delexicon polymer material generates radial compression deformation to absorb the impact of motor start-up and shutdown. The first reinforcing fiber resists axial tensile force, and the second reinforcing fiber suppresses circumferential shear through a spiral winding structure. Attached Figure Description

[0021] Please see Figures 1-5 A motor coupling structure includes two mounting mechanisms 1, with a transmission mechanism 2 mounted on one end of each mounting mechanism 1.

[0022] Furthermore, the transmission mechanism 2 includes a mounting sleeve 101, one end of which is fixedly connected to a mounting base 106. One end of the mounting base 106 has a groove 102, and a mounting bolt 103 is mounted on the mounting base 106. The bottom of the mounting bolt 103 passes through the groove 102 and extends to the bottom of the mounting base 106. A mounting nut 105 is threaded onto the bottom of the mounting bolt 103.

[0023] Furthermore, a locking block 107 is installed on the front side of the mounting sleeve 101, and a fastening bolt 108 is threadedly connected to the locking block 107 and the mounting sleeve 101.

[0024] Furthermore, the transmission mechanism 2 is located within the groove 102 and is fitted onto the surface of the mounting bolt 103.

[0025] Furthermore, the mounting bolt 103 has a fixing part 104 on its surface that works in conjunction with the transmission mechanism 2, and the surface of the groove 102 is fixedly connected to the inner wall of the fixing part 104.

[0026] Furthermore, the transmission mechanism 2 includes a transmission component 201, which is annular and made of dextromethorphan polymer material.

[0027] Furthermore, a first reinforcing fiber 202 is provided at the center of the transmission component 201, and the first reinforcing fiber 202 is made of steel wire.

[0028] Furthermore, a second reinforcing fiber 203 is installed inside the transmission component 201. The second reinforcing fiber 203 is distributed around the first reinforcing fiber 202, and the second reinforcing fiber 203 is a number of intertwined carbon fiber ropes.

[0029] Furthermore, a first motor 3 is mounted on one mounting mechanism 1, and a first drive shaft 4 is mounted on another mounting mechanism 1. A load 5 is mounted on the output end of the first drive shaft 4, and a second drive shaft 6 is mounted on the output end of the load 5.

[0030] Furthermore, it also includes a second motor 7, the output shaft of the second motor 7 is fitted with a first transmission wheel 8, the surface of the first transmission shaft 4 is fitted with a second transmission wheel 10, and the surfaces of the first transmission wheel 8 and the second transmission wheel 10 are connected by a transmission belt 9.

[0031] Furthermore, the mounting sleeve 101 and the locking block 107 are fitted onto the output shaft of the first motor 3 and the input end of the first transmission shaft 4, and the fastening bolt 108 fastens the locking block 107 and the mounting sleeve 101.

[0032] The first motor 3 clamps the output shaft through the mounting sleeve 101 and the clamping block 107. The torque is transmitted to the first drive shaft 4 through the transmission component 201, driving the load 5 to work. The annular dehydrogenated polymer material of the transmission component 201 compensates for installation errors through shear deformation, and at the same time, it uses internal steel wire and carbon fiber rope to enhance tensile strength. The second motor 7 works in conjunction with the first drive shaft 4 through the transmission belt 9, forming dual power redundancy. In low-speed, high-torque conditions, the main motor 3 drives independently, while in high-speed, light-load conditions, the second motor 7 accelerates synchronously.

[0033] When subjected to load, the delexicon polymer material undergoes radial compression deformation to absorb the impact of motor start-up and shutdown. The first reinforcing fiber 202 resists axial tensile force, and the second reinforcing fiber 203 suppresses circumferential shear through a helical winding structure.

[0034] A 0.5mm gap is reserved between the groove 102 and the fixing part 104 to allow ±0.3mm axial displacement. The elastic deformation of the transmission component 201 allows a maximum included angle of 3° between the center lines of the two shafts.

[0035] The composite structure of delexipolymer, steel wire rope and carbon fiber reinforcement enables a torque density of 3.6 N·m / kg, and the weight is reduced compared to metal couplings of the same specifications. In the application of UAV gimbals, the reduced weight of the coupling reduces the inertial torque of the gimbal and improves the pitch angle response speed.

[0036] The first motor 3 is responsible for the reference torque output, and the second motor 7 achieves power multiplication through the transmission belt 9. The system's peak torque can reach 9 N·m. In the scenario of a sweeping robot, the collaboration of the two motors extends the battery life.

[0037] The coupling can be disassembled by loosening the fastening bolt 108 and the mounting bolt 103, and the transmission component 201 can be replaced in just 3 minutes.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
