Plate Mechanical Reducer Gear Box

With the continuous improvement of the requirements for the reducer, in specific use occasions, a reducer should realize the output of a variety of speeds and torques, which is convenient for saving space and using costs. However, the traditional reducer can only achieve a kind of output of rotation element and torque, which cannot meet the increasing use requirements. The invention content is aimed at the deficiency of the prior art, and the utility model provides a kind of compact structure, stable transmission, can output the 23-roller sub-gear box reducer that can output multi-speed, a variety of torque. In order to solve the above-mentioned technical problem, the technical scheme adopted by the utility model is a 23-roller tooth box reducer, comprises a box body placed on the base and 23 gear shafts that are supported on the box body by penetration, 11 gear shafts are arranged in parallel above 12 gear shafts,12 gear shafts are sequentially divided into odd sequence numbers, 11 gear shafts are successively divided into even sequence numbers, the 3rd, 11th, 19th gear shafts are provided with front and rear two sections of teeth, the 3rd, 11th, 19 gear shaft both ends are supported by bearing and penetrate out of the box, the remaining 20 gear shaft one end is all sealed and connected in the box by cover, the other end is supported by the bearing and penetrates out of the box, the remaining 20 gear shafts are all provided with a section of tooth; the front tooth of described 3rd gear shaft meshes the tooth of the 2nd gear shaft, the tooth part of the 2nd gear shaft meshes the tooth part of the 1st gear shaft, the rear section tooth part of the 3rd gear shaft meshes the tooth part of the 4th gear shaft, the tooth part of the 4th gear shaft meshes the tooth part of the 5th gear shaft, The teeth of the 5th gear shaft mesh the teeth of the 6th gear shaft, and the teeth of the 6th gear shaft mesh the teeth of the 7th gear shaft;According to the above-mentioned meshing transmission relationship, the rear section tooth part of the 11th gear shaft meshes the tooth part of the 10th, 9th, 8th gear shaft sequentially, the front section tooth part of the 11th gear shaft meshes the tooth part of the 12th, 13th, 14th gear shaft in turn, the front tooth part of the 19th gear shaft meshes the tooth part of the 18th, 17th, 16th, 15th gear shaft, and the rear tooth part of the 19th gear shaft meshes the tooth part of the 20th, 21st, 22nd, 23rd gear shaft.Described box body comprises front, rear box plate and left and right box plate, and front, rear box plate and left and right box plate are combined into a rectangular box body, and 23 gear shafts are supported on front and rear box plate and parallel to left and right box plate. The utility model discloses 23 gear shafts are combined and encapsulated by combination box, the gear shaft that acts on three inputs transmits torque to the remaining 20 gear shafts respectively, and the gear shaft that each input gear shaft meshes both sides of it sequentially outputs two different speeds and torque, has taken into account gearbox volume, multi-speed, multi-torque requirements, and the gear shaft of each input gear shaft meshing transmission takes only a small part of the total gear shaft relatively, and the load of each output gear shaft is relatively small, effectively prolongs service life. The overall structure of the reducer is compact, easy to process and assemble, the installation is firm, the transmission is stable, and the applicable functions are many.
