Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in FIGS. 1-3, a distributed driving type linear transmission mechanism comprises: the fixing plate 2, the gear transmission system 3 and the plurality of outer rotor motors 1 are arranged on the fixing plate 2, the gear transmission system 3 comprises a rack 33 and a plurality of output gears 31 and coordination gears 32, the output gears 31 and the coordination gears 32 are arranged at intervals and meshed with each other, the outer rotor motors 1 are used for driving the output gears 31 and the coordination gears 32 to rotate, and the rack 33 is meshed with all the output gears 31.
When the fixing plate is specifically installed, the fixing plate is not limited to be placed on a certain side surface and can be exchanged, and the operation of the mechanism is not influenced.
In a further embodiment, the external rotor motors 1 are correspondingly arranged on the inner side surfaces of the output gear 31 and the coordination gear 32, and the rotors of the external rotor motors 1 are respectively matched with the output gear 31 and the coordination gear 32.
Specifically, the outer rotor motor rotor 12 is arranged in the inner holes of the output gear 31 and the coordination gear 32, and the outer diameter of the rotor 12 of the outer rotor motor 1 is the same as the inner hole diameters of the output gear 31 and the coordination gear 32, so that the output gear 31 and the coordination gear 32 are driven to rotate by the outer rotor motor 1.
In a further embodiment, the protruding shaft 21 of the fixing plate 2 is disposed in a hollow hole inside the stator 11 of the external rotor motor 1, and the diameter of the protruding shaft is the same as the inner diameter of the hollow hole, and the external rotor motor 1 is fixed on the fixing plate 2 through the stator.
The working process of the invention is as follows: the motor stator 11 and the fixing plate 2 are both fixed. The rack 33 is driven to move by taking the output gear 31 as a direct driving source. Subsequently, as the rack continuously moves, part of the output gears 31 are disengaged from the rack 3, and at this time, the disengaged output gears 31 cannot directly drive the rack 33 to move, and the torque is transmitted to other output gears 31 through the nearest coordination gear 32 to continuously drive the rack 33. That is, the outer rotor motor 1 provided in the output gear and the coordinating gear always drives the rack 33 to move no matter where the rack is located during the whole operation.
In the whole movement process, no matter where the rack is located, all the external rotor motors 1 of the system directly or indirectly drive the rack 33 to run through the output gear 31 or the coordination gear 32, and the driving force received by the rack 33 is always the resultant force of all the external rotor motors 1.
Compared with the prior art, the external rotor motor is arranged inside the gear, so that the space occupation is greatly reduced, the effective space utilization rate is greatly improved, the multi-motor distributed driving is adopted, and the flexibility of the system design is greatly improved.
The invention mainly transmits a design idea, namely, the distributed driving of the motors is realized through gear transmission, all the motors in the system are in a resultant force working mode, and the motor clusters are used for replacing single motors, so that the limitation of the structural shape of the transmission motors is broken, the arrangement shape of the motor clusters can be arbitrary, and the practical installation space constraint is taken as the standard, so that the motor arrangement mode protected by the invention is not limited to horizontal line arrangement shown in the figure, and all the transmission schemes adopting the design idea, namely, the transmission scheme of combining a plurality of motors to simultaneously drive in a resultant force mode through gear meshing are protected by the invention.
