The bearing 19 seats 15 are used for mounting the driving wheel 14. The transmission structure 17 serves to transmit the driving force of the drive motor 12 to the drive wheels 14.
As a concrete structure, a motor shaft of the drive motor 12 is connected to the reducer 13. Both ends of the driving shaft 16 are rotatably connected to the bearing 19 seats 15, respectively. The driving wheel 14 is sleeved on the periphery of the driving shaft 16. The reducer 13 is provided with two output shafts.
Further, the transmission structure 17 includes: two drive sprockets 171, two driven sprockets 172, and two chains 173. The two drive sprockets 171 are connected to one end of the two output shafts, respectively. Two driven sprockets 172 are respectively connected to both ends of the drive shaft 16. One of the two chains 173 is fitted around the outer circumference of one of the two driving sprockets 171 and one of the two driven sprockets 172. The other of the two chains 173 is fitted around the outer peripheries of the other of the two driving sprockets 171 and the other of the two driven sprockets 172. Specifically, one of the two drive sprockets 171 and one of the two driven sprockets 172 are located on one side of one of the two bearing 19 seats 15. The other of the two drive sprockets 171 and the other of the two driven sprockets 172 are located on one side of the other of the two bearing 19 seats 15.
Specifically, the drive motor 12 drives two output shafts of the reduction gear 13 via a motor shaft. The two output shafts respectively drive the two driving sprockets 171 to rotate. When the two driving sprockets 171 rotate, the two chains 173 are driven to rotate, and the driven sprocket 172 is driven to rotate. The driven sprocket 172 is keyed to the drive shaft 16 to rotate the drive shaft 16 and thus the drive wheel 14. Two chains 173 are respectively driven through two output shafts, so that two ends of the driving shaft 16 are driven to rotate simultaneously, the transmission structure 17 is stable, the structure size is small, and the required installation space in the vertical direction is small.
The chain wheel driving structure 10 applicable to the differential transfer robot in the scheme has a small structural volume, reduces the required installation space, and simultaneously has a low gravity center of the driving structure, so that the forklift of the transfer robot can realize double-wheel differential motion to rotate in situ.
As a specific embodiment, the rotation axes of the two output shafts coincide and the two driving sprockets 171 are respectively disposed at the ends of the two output shafts far away from each other.
As a specific embodiment, the axis of rotation of the output shaft is parallel to the axis of rotation of the drive shaft 16 and perpendicular to the axis of rotation of the motor shaft of the drive motor 12.
As a specific embodiment, both the two drive sprockets 171 and the two driven sprockets 172 are provided with the spacers 18. The spacer 18 serves to limit the axial position of the chain 173, thereby preventing the chain 173 from falling off the driven sprocket 172 and ensuring structural stability. As a specific structure, two of the four spacers 18 are fixed to the ends of the two drive sprockets 171, which are away from each other, by screws, respectively. The other two of the four spacers 18 are fixed by screws to the mutually distant ends of the two driven sprockets 172, respectively.
As a specific embodiment, both bearings 19 seats 15 are provided with mounting holes 151. The mounting hole 151 is for passing the drive shaft 16 therethrough. Bearings 19 are provided in the two mounting holes 151. The bearing 19 is used to support and protect the drive shaft 16. Specifically, the bearing 19 is fitted around the outer periphery of the drive shaft 16 and located between the hole wall of the mounting hole 151 and the outer peripheral surface of the drive shaft 16.
In a specific embodiment, a shaft sleeve 20 is arranged between the bearing 19 and the driving wheel 14 and the seat 15. The sleeve 20 serves to limit the axial position of the drive wheel 14. The shaft sleeve 20 is sleeved on the periphery of the driving shaft 16 and two ends of the shaft sleeve respectively contact the bearing 19 seat 15 and the driving wheel 14.
Further, a bushing 20 is provided between the two bearing 19 seats 15 and the driving wheel 14. Two bushings 20 are respectively located on both sides of the drive wheel 14 for limiting the axial position of the drive wheel 14 from both sides. The two bushings 20 are sleeved on the periphery of the driving shaft 16 and two ends of the two bushings 20 respectively contact the bearing 19 seat 15 and the driving wheel 14. The arrangement is more stable.
As a preferred embodiment, the sprocket drive structure 10 adapted to the differential transfer robot further includes: a tensioning device 21. The tensioning device 21 is used to tension the two chains 173. Specifically, the tensioner 21 includes: a tension plate 211 and a plurality of tension screws 213. The tension plate 211 is fixed to one end of the two bearing 19 seats 15. The tension plate 211 is formed with a plurality of threaded holes 212 for fitting a plurality of tension screws 213. The plurality of tightening screws 213 pass through the plurality of threaded holes 212, respectively, and one end thereof contacts the housing 131 of the reduction gear 13.
Further, the mounting chassis 11 is provided with a plurality of kidney-shaped holes 111. The housing of the reduction gear 13 is formed with a plurality of screw mounting holes 151. The speed reducer 13 is fixed to the mounting chassis 11 by a plurality of screws passing through the kidney-shaped hole 111 and screwing into the threaded mounting hole 151. When the chain 173 needs to be tensioned, the screw screwed into the screw mounting hole 151 may be screwed out until the position of the speed reducer 13 moves. Tensioning screw 213 is then adjusted and reducer 13 is pushed through the housing of reducer 13 to a displaced position until chain 173 will be tensioned. At this time, the screw is screwed into the screw mounting hole 151 again and tightened.
Specifically, the number of the tension screws 213 is 2. Two tensioning screws 213 adjust the position of speed reducer 13 to tension chain 173, and simple structure and stability are higher.
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.
