Description

Technical Field

[0001] The present invention relates to the technical field of motors, and more specifically, to a small-space modular motor reduction assembly. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor usually includes a stator and a rotor. The stator includes a stator core and a coil winding wound on the stator core. The rotor includes a rotating shaft and a rotor core sleeved on the rotating shaft. A permanent magnet is provided on the outer edge of the rotor core. The main function of the motor is to generate driving torque as a power source for electrical appliances or various machines. A reducer is an independent component composed of a gear transmission, a worm transmission, a gear, and a worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between a transmission part and a working machine. According to the number of transmission stages, it can be divided into single-stage and multi-stage reducers. In the industrial field, the combination of motor and reducer is a common and key configuration. Therefore, the motor reduction is combined together, so that the reduction drive can be realized, thereby increasing the torque of the transmission, especially in low practical space, which requires a closer fit so that it can be used in low practical space and make full use of the assembly space.

[0003] In the existing public documents, the patent with patent announcement number CN218472964U discloses a reduction DC motor based on modular design. The motor assembly is provided with a number of support rods to enable the staff to dock an appropriate number of reduction gears with the fixed seat, thereby realizing modular assembly. In this technology, lubricating grease is applied between the gears, and the transmission shaft is decelerated by the reduction gears. The lubricating grease reduces the friction between the gears, avoids gear wear and damage, and thus increases its overall service life. However, the modular motor reduction assembly still has the following problems during use.

[0004] When the modular motor reduction assembly is assembled and used in a low practical space, the external cavity needs to be docked, so as to wrap and assemble the entire motor and the reduction part to increase the stability of the drive. During the motor deceleration movement, long-term drive will cause the bolts of the external cavity to loosen, and the transmission of the motor reduction part will also be offset. Once the looseness is not discovered in time for repair and reinforcement, the modular motor reduction assembly will become loose during use, causing the drone to malfunction and be damaged in the air. The maintenance timeliness of the modular motor reduction assembly is poor, so a small space modular motor reduction assembly is needed. Summary of the invention

When the fluctuation value sensed by the positioning distance sensor exceeds the fluctuation range set by the wireless controller, the wireless controller remotely alerts the background computer.

[0013] Technical effects and advantages of the present invention: 1. The present invention uses a lateral offset sensing mechanism. When the sensor sleeve strip is offset, friction and rolling occur between the sensor sleeve strip and the friction roller. The sensor sleeve strip drives the friction roller to roll, and the support shaft senses and rotates on the first angle sensor. The angle value sensed by the first angle sensor exceeds the offset distance set by the wireless controller, and the sensor sleeve strip is laterally offset. When the sensor sleeve strip is offset, it drives the connecting roller to contact and roll, so that the connecting roller drives the linkage shaft to rotate, the pulley drives the driving belt to drive, and the driving belt drives the sensor pulley to drive.

The sensing slide column is offset longitudinally forward and backward on the distance sensor. The sleeve block supports the distance sensor. The distance sensor is used to sense the distance between the distance sensor and the sensing slide column. When the distance value sensed by the distance sensor exceeds the fluctuation range set by the wireless controller, the wireless controller remotely reminds the background computer, so that the longitudinal looseness problem at the connection between the cavity shell and the plug-in shell can be known in time. In this way, the self-inspection and maintenance of the modular motor reduction assembly are more timely.

[0015] 3. The present invention adopts a deceleration offset sensing component. When the deceleration shaft part fluctuates, the deceleration gear causes the driven gear to rotate and fluctuate, and the driving gear shaft fluctuates and deviates inside the pressure sleeve. The positioning distance sensor senses the driving gear shaft. When the fluctuation value sensed by the positioning distance sensor exceeds the fluctuation range set by the wireless controller, the wireless controller remotely reminds the background computer to know that the deceleration part inside the deceleration housing has an offset problem and needs to be repaired in time. In this way, the self-inspection and maintenance of the modular motor deceleration assembly are more timely, and the self-inspection faults can be accurately repaired in time.

[0016] According to the mutual influence of the above-mentioned multiple functions, firstly, the lateral offset sensing can be realized in time for the front and back of the sensor sleeve strip, and secondly, the longitudinal looseness problem at the connection between the cavity shell and the plug-in shell can be known in time, and finally the offset problem of the deceleration part inside the reduction housing can be known, and timely maintenance is required. In summary, the lateral and longitudinal self-inspection offset sensing of the cavity shell and the plug-in shell can be realized, and the offset self-inspection sensing of the deceleration part inside the reduction housing can also be realized. Rapid self-inspection and maintenance can be realized in a low practical space, making the self-inspection and maintenance of the modular motor reduction assembly more timely.

[0032] In this embodiment, as shown in the attached Figure 7-8 As shown, a stator 27 is fixedly installed inside the drive shell 4, and a rotor 28 is rotatably connected inside the stator 27, and the outer walls of both ends of the rotor 28 are rotatably connected to bearing sleeves 29; a docking plate 30 is fixedly connected to one side of the stator 27, and a wireless controller 31 is plugged into one side of the docking plate 30, and the outer walls of the two bearing sleeves 29 are fixedly connected to the drive shell 4, so that the wireless controller 31 is supported by the drive shell 4, and the docking plate 30 supports the stator 27, and the stator 27 and the drive shell 4 are firmly connected together, and the stator 27 causes the rotor 28 to rotate, and the rotor 28 rotates stably inside the two bearing sleeves 29, and the output end of the rotor 28 drives the reduction shaft 32 to rotate synchronously, and the reduction shaft 32 causes the reduction gear 33 to rotate.

[0033] In this embodiment, as shown in the attached Fig. 9 As shown, the deceleration offset sensor assembly includes a deceleration shaft 32 rotatably arranged inside the deceleration housing 3; a deceleration gear 33 is fixedly connected to the outer wall of the deceleration shaft 32, and a driven gear 34 is fixedly connected to one side of the deceleration gear 33, an auxiliary gear 35 is meshingly connected to the outer wall of the deceleration gear 33, and a linkage gear 36 is meshingly connected to the outer wall of the driven gear 34; a positioning groove block 37 is provided on one side of the linkage gear 36, and the positioning groove block 37 is fixedly connected to the deceleration housing 3, and a positioning groove block 37 is fixedly installed on one side of the inner wall A positioning distance sensor 38 is provided, and a driving gear shaft 39 is rotatably connected to one side of the positioning groove block 37, and an auxiliary gear shaft 40 is meshingly connected to one side of the outer wall of the driving gear shaft 39, and the outer wall of the auxiliary gear shaft 40 is rotatably connected to the positioning groove block 37; the outer wall of the auxiliary gear shaft 40 is plugged into the inner wall of the linkage gear 36; a pressure sleeve 41 is rotatably connected to one side of the outer wall of the driving gear shaft 39, and a positioning sleeve block 42 is fixedly installed on the outer wall of the pressure sleeve 41, and the positioning sleeve block 42 is fixedly connected to the reduction housing 3 by bolts.

[0034] The use principle of the small space modular motor reduction assembly of the present invention is as follows: Step 1. When driving and assembling, insert the two reduction housings 3 into the cavity housing 1, and at the same time, firmly connect the drive housing 4 and the reduction housing 3, so that the plug-in operation between the cavity housing 1 and the plug-in housing 2 is completed. By rotating multiple screws 26, the screws 26 firmly lock the cavity housing 1 and the plug-in housing 2, and at the same time, fix the cavity housing 1 in the low practical space of the drone to complete the drive installation operation.

[0035] The wireless controller 31 is supported by the drive shell 4, and the docking plate 30 supports the stator 27. The stator 27 is firmly connected to the drive shell 4, so that the wireless controller 31 supplies power to the stator 27, and the stator 27 makes the rotor 28 rotate. The rotor 28 rotates stably inside the two bearing sleeves 29, so that the output end of the rotor 28 drives the reduction shaft 32 to rotate synchronously, and the reduction shaft 32 makes the reduction gear 33 rotate.

[0036] Then the reduction shaft 32 rotates stably inside the reduction housing 3, the reduction gear 33 meshes with the auxiliary gear 35 to rotate, the reduction gear 33 drives the driven gear 34 to mesh and rotate, the driven gear 34 makes the linkage gear 36 mesh and rotate, the linkage gear 36 rotates on the positioning groove block 37, the linkage gear 36 makes the auxiliary gear shaft 40 mesh and rotate inside the positioning groove block 37, the auxiliary gear shaft 40 makes the driving gear shaft 39 mesh and rotate, and the auxiliary gear shaft 40 rotates stably on the inner wall of the pressure sleeve 41. The reduction housing 3 provides a stable supporting force for the positioning sleeve block 42, and the positioning sleeve block 42 realizes a stable limiting operation on the pressure sleeve 41, ensuring that the shaft end of the driving gear shaft 39 performs a stable transmission operation.

[0037] Step 2, during lateral offset sensing, when multiple screws 26 become loose during use, and the lateral offset fluctuations are generated at the connection between the cavity shell 1 and the plug-in shell 2, the cavity shell 1 drives the concave block 5 to move laterally, the concave block 5 drives the support 6 to move laterally, the support 6 drives the sensing sleeve strip 7 to move laterally, and the sensing sleeve strip 7 and the friction roller 8 roll frictionally, the sensing sleeve strip 7 drives the friction roller 8 to roll, the friction roller 8 drives the support shaft 9 to rotate, the support shaft 9 rotates inside the sleeve 10, and at the same time the plug-in shell 2 supports the reinforcement block 20, the reinforcement block 20 provides a stable support force for the sleeve 10, so that the support shaft 9 stably rotates inside the sleeve 10. At the same time, the support shaft 9 senses rotation on the first angle sensor 11, and the reinforcement block 20 provides a stable supporting force for the reinforcement shaft 18. The reinforcement shaft 18 supports the first angle sensor 11, thereby increasing the stability of the first angle sensor 11. The lateral movement of the sensing sleeve 7 can be sensed by the first angle sensor 11 to sense the displacement angle position, thereby knowing the offset position of the lateral movement of the sensing sleeve 7. When the angle value sensed by the first angle sensor 11 exceeds the offset distance set by the wireless controller 31, the sensing sleeve 7 is laterally offset.

[0038] At the same time, when the sensing sleeve strip 7 deviates, it will drive the connecting roller 12 to contact and roll, so that the connecting roller 12 drives the linkage shaft 13 to rotate, and the linkage shaft 13 rotates stably inside the bearing sleeve 19, and the linkage shaft 13 drives the pulley 14 to rotate, and the pulley 14 drives the driving belt 15 to transmit, and the driving belt 15 drives the sensing pulley 16 to transmit, and the sensing pulley 16 drives the output end of the second angle sensor 17 to rotate, and the second angle sensor 17 can sense the angle value. When the angle value sensed by the second angle sensor 17 exceeds the angle value set by the wireless controller 31, it can be known that the front and rear of the sensing sleeve strip 7 can realize lateral offset sensing, so that the wireless controller 31 remotely reminds the background computer, and the reminder data is that there is a lateral loose problem at the connection between the cavity shell 1 and the plug shell 2.

[0039] Step 3, when sensing longitudinal displacement, since the connecting roller 12 and the friction roller 8 are both made of rubber material, when the cavity shell 1 is longitudinally offset forward and backward, the cavity shell 1 drives the concave block 5 to longitudinally offset forward and backward, the concave block 5 drives the pillar 6 to longitudinally offset forward and backward, the pillar 6 causes the sensing sleeve strip 7 to longitudinally offset forward and backward, the sensing sleeve strip 7 drives the slider 22 to longitudinally offset forward and backward, the slider 22 drives the sensing slide post 25 to achieve longitudinal offset forward and backward, and the sensing slide post 25 is longitudinally offset forward and backward on the distance sensor 23. At the same time, the reinforcement block 20 supports the sleeve strip 21, the sleeve strip 21 supports the sleeve block 24, and the sleeve block 24 supports the distance sensor 23. The distance between the distance sensor 23 and the sensing slide post 25 is sensed by the distance sensor 23. When the distance value sensed by the distance sensor 23 exceeds the fluctuation range set by the wireless controller 31, the wireless controller 31 remotely reminds the background computer, and the reminder data is that there is a longitudinal loose problem at the connection between the cavity shell 1 and the plug shell 2.

[0040] Step 4: During the deceleration offset sensing, when the deceleration shaft 32 fluctuates, the deceleration shaft 32 drives the deceleration gear 33 to rotate and fluctuate, and the deceleration gear 33 causes the driven gear 34 to rotate and fluctuate, and the driven gear 34 drives the linkage gear 36 to rotate and fluctuate, and the linkage gear 36 causes the auxiliary gear shaft 40 to fluctuate and deviate, and the auxiliary gear shaft 40 drives the driving gear shaft 39 to fluctuate and deviate, so that the driving gear shaft 39 fluctuates and deviates inside the pressure sleeve 41, so that the positioning distance sensor 38 senses the driving gear shaft 39. When the fluctuation value sensed by the positioning distance sensor 38 exceeds the fluctuation range set by the wireless controller 31, the wireless controller 31 remotely reminds the background computer, so that it is known that the deceleration part inside the deceleration housing 3 has an offset problem, and timely maintenance is required.
