Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a novel synchronous belt drive speed reducing mechanism 10 includes: a drive motor 11 and a reducer 12. The power output from the drive motor 11 is reduced in speed by the speed reducer 12 and output to the transmission mechanism. The drive motor 11 and the speed reducer 12 are mounted to the mounting frame.
As a further structure, the novel synchronous belt drive speed reducing mechanism 10 further includes: the device comprises a coupling 13, a transmission shaft 14, a first synchronous wheel 15, a second synchronous wheel 16, a synchronous belt 17 and an output gear 18. One end of the transmission shaft 14 is connected to a motor shaft of the driving motor 11 through a coupling 13 and the other end is rotatably connected to the mounting frame. A first synchronizing wheel 15 is connected to the other end of the transmission shaft 14. The second synchronizing wheel 16 is connected to the input shaft of the speed reducer 12. The synchronous belt 17 is sleeved on the peripheries of the first synchronous wheel 15 and the second synchronous wheel 16. The output gear 18 is keyed to the output shaft of the reducer 12.
Specifically, the driving motor 11 drives the transmission shaft 14 to rotate through the coupling 13. When the transmission shaft 14 rotates, the first synchronizing wheel 15 drives the synchronizing belt 17 to rotate, so as to drive the second synchronizing wheel 16 to rotate. The synchronous belt 17 transmission structure reduces the rotation speed output by the driving motor 11, transmits the reduced rotation speed to the speed reducer 12, reduces the speed again, and finally realizes power output through the speed reducer 12.
Novel synchronous belt drive reduction gears 10 among the above-mentioned scheme has simplified overall structure through using shaft coupling 13 and synchronous belt 17 transmission cooperation speed reducer 12 to slow down, and required installation space is less, and the installation is simple, the cost is reduced.
As a specific embodiment, the driving motor 11 is mounted to the mounting frame through a motor fixing plate 19. The motor fixing plate 19 is formed with a first through hole 191. The first through hole 191 is for a motor shaft of the driving motor 11 to pass through to be connected to the coupling 13, thereby transmitting torque to the transmission shaft 14 through the coupling 13.
In a specific embodiment, the reducer 12 is provided with a first fixing plate 20 and a second fixing plate 21 at both ends thereof. The first fixing plate 20 and the second fixing plate 21 are disposed in parallel. Both ends of the speed reducer 12 are mounted to the mounting frame through a first fixing plate 20 and a second fixing plate 21, respectively. The first and second fixing plates 20 and 21 are formed with second and third through holes 201 and 211, respectively. The second through hole 201 is used for the input shaft of the speed reducer 12 to pass through to connect with the second synchronizing wheel 16. The third through hole 211 is used for the output shaft of the speed reducer 12 to pass through to connect with the output gear 18.
Further, the second fixing plate 21 is located between the motor fixing plate 19 and the first fixing plate 20. Therefore, the position of the output gear 18 is located at the middle position of the whole novel synchronous belt drive speed reducing mechanism 10, and the good centering performance is achieved, so that the installation stability of the mechanism is improved. At the same time, such a structure contributes to reducing the installation space of the entire mechanism.
Further, the first fixing plate 20 and the second fixing plate 21 are also formed with a fourth through hole 202 and a fifth through hole 212, respectively. Both ends of the transmission shaft 14 are rotatably connected in the fourth through hole 202 and the fifth through hole 212, respectively. The mounting structure can further simplify the structure, reduce the number of mounting parts and reduce the mounting volume required by the whole body. Meanwhile, a first bearing 22 is arranged between one end of the transmission shaft 14 and the hole wall of the fifth through hole 212, and a second bearing 23 is arranged between the other end of the transmission shaft 14 and the hole wall of the fourth through hole 202. This ensures the stability of the rotation of the drive shaft 14.
As a preferred embodiment, the novel synchronous belt drive reduction mechanism 10 further includes a tensioning assembly 24. The tension assembly 24 is used for tensioning the timing belt 17 to ensure the stability of the rotation of the timing belt 17.
As a specific structure, the tension assembly 24 includes: a tension fixing plate 241, a tension fixing shaft 243, a tension shaft 244 and a tension wheel 245. The tension fixing plate 241 is connected to the first fixing plate 20 by a tension fixing shaft 243. One end of the tension shaft 244 is adjustably connected to the tension fixing plate 241. The tension pulley 245 is fitted around the outer periphery of the tension shaft 244 and presses the outer side surface of the timing belt 17. The tension pulley 245 can press the outer periphery of the timing belt 17 to tension the timing belt 17. When the synchronous belt 17 is loose, the position of the tension wheel 245 can be adjusted by adjusting the position of the tension shaft 244 relative to the tension fixing plate 241, so that the tension wheel 245 can tension the synchronous belt 17 in real time.
Further, the tension fixing plate 241 is formed with a kidney-shaped hole 242. One end of the tension shaft 244 is adjustably connected to the tension fixing plate 241 through the kidney-shaped hole 242 by an adjustment screw.
Further, the extending direction of the kidney-shaped hole 242 along the long axis thereof is perpendicular to the extending direction of the timing belt 17 along the long axis thereof. This can improve the range of adjustment of tensioning axle 244, guarantee the validity of adjusting take-up pulley 245.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
