Embodiment Construction
[0025] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0026] refer to Figure 1 to Figure 5 , the present invention discloses a multi-gear set meshing structure 100, which includes three sets of gear sets, which are respectively the first gear set 10, the second gear set 20, the third gear set 30 and two rotating shafts 40 of the same size. The first gear set 10 includes two intermeshing splitter gears 11 , the second gear set 20 includes two intermeshing splitter gears 21 , the third gear set 30 includes intermeshing splitter gears 31 , The two split gears 11 of the first gear set 10 are respectively installed on the two rotating shafts 40, and the two split gears 21 of the second gear set 20 are respectively installed on the two rotating shafts. On the shaft 40, the two split gears 31 of t...

The invention discloses a multi-gear-set engagement structure. The structure comprises N gear sets and two rotating shafts; N is an integer not less than 2; each gear set includes two component gears engaged with each other; two component gears in each gear set are respectively mounted on the two rotating shafts; the engaged points of two adjacent gear sets are staggered by a preset included angle around the axis of any one rotating shaft; and when the N gear sets act, at least one gear set is located in a double-gear engaged area. The component gears of the adjacent gear sets are staggered by a certain angle, so that the contact ratio of the gears is effectively increased, the load of the gears is reduced, the collapse of the gears is prevented, and the service life of the gears is prolonged. Each component gear is thinner, so that a thin material can be used for machining, a punching process can be used in machining, the production efficiency is high, the mold life is effectively prolonged, and the precision of the gears is effectively improved. In addition, the invention further discloses a paper shredder with the multi-gear-set engagement structure.
Description
technical field [0001] The invention relates to a driving assembly, in particular to a multi-gear meshing structure. Background technique [0002] The existing gear drive assembly generally includes two gears meshing with each other. When in motion, the driving mechanism controls one gear to rotate, and the gear drives the other gear meshed with it to rotate, thereby driving the controlled component to move. However, because some existing gears are often limited due to the degree of overlap, the load is relatively large when the gear rotates, and it is easy to vibrate, and the service life of the gear is low. Contents of the invention [0003] The purpose of the present invention is to provide a multi-gear set meshing structure, which can effectively increase the overlap degree of gears, reduce the load of each set of gear sets, and increase the service life of the gears. [0004] Another object of the present invention is to provide a paper shredder having a multi-gear s...
