This gear transmission system is formed by connecting by a plurality of gear driving mechanisms, can realize the variation of a plurality of gear transmission speeds as required, and is simple in structure, be easy to realize.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the utility model gear driving mechanism.
Fig. 2 is the structural representation of the utility model gear transmission system.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, this gear driving mechanism 1 comprises an output shaft 19 and input shaft 11, and input shaft 11 cogs by first overrunning clutch 12 and first and 13 is connected, and it also connects clutch 14 and second by first and cogs and 15 be connected.The effect of first overrunning clutch 12 is can make input shaft 11 drive first to cog and 13 rotate, and first cog and 13 can not drive input shaft 11 and rotate.Output shaft 19 cogs by second overrunning clutch 18 and the 3rd and 17 is connected, and it also connects clutch 16 and second by second and cogs and 15 be connected.The effect of second overrunning clutch 18 is to make the 3rd to cog and 17 can drive output shaft 19 and rotate, and output shaft 19 can not drive the 3rd and cogs and 17 rotate.First 13 and first lower gear 22 engagement that cogs, second 15 and second lower gear, 21 engagements that cog, the 3rd the 17 and the 3rd lower gear 20 that cogs meshes, and first lower gear 22, second lower gear 21, that the 3rd lower gear 20 passes through transmission shaft 23 is coaxial fixedly connected.
First cogs the velocity ratio of 13 and first lower gear 22 less than second velocity ratio that cogs 15 and second lower gear 21, and second cogs the velocity ratio of 15 and second lower gear 21 less than the 3rd velocity ratio that cogs the 17 and the 3rd lower gear 20.Second velocity ratio 1: 1 that cogs 15 and second lower gear 21 wherein.
During this gear driving mechanism work, be divided into following four kinds of situations:
1) when the first connection clutch 14, when the second connection clutch 16 all is failure to actuate, promptly second cog and 15 neither be connected also and be not connected with input shaft 11 with output shaft 19, this moment, input shaft 11 rotated under the drive of external drive unit, and drive first simultaneously and cog and 13 rotate, first cogs 13 drives first lower gear 22 and rotates, first lower gear 22 drives second lower gear 21 simultaneously by transmission shaft 23, the 3rd lower gear 20 rotates, and then second lower gear 21 drive second and cog and 15 rotate, the 3rd lower gear 20 drives the 3rd and cogs and 17 rotate, since second cog 15 not with output shaft 19, input shaft 11 connects, be idle running, the 3rd cogs 17 can drive output shaft 19 and rotate and finish transmission process, this moment the velocity ratio minimum.
2) connect clutch 14 actions when first, and second when connecting clutch 16 and being failure to actuate, promptly second 15 input shafts 11 that cog connect, and are not connected with output shaft 19.Input shaft 11 rotations this moment can drive first simultaneously and cog 13, second cogs 15 rotates, because first cogs the velocity ratio of 13 and first lower gear 22 less than second velocity ratio that cogs 15 and second lower gear 21, therefore cog this moment second and 15 can drive second lower gear 21 and rotate, second lower gear 21 can drive first lower gear 22 simultaneously by transmission shaft 23, the 3rd lower gear 20 rotates, this moment, cog 13 velocity ratio of first lower gear 22 and first was greater than cog 15 velocity ratio of second lower gear 21 and second, therefore first cog 13 rotational speed will be greater than the speed of input shaft 11, under the effect of first single clutch, first cogs 13 can not impact input shaft 11.The 3rd lower gear 20 will drive the 3rd and cog and 17 rotate, and the 3rd cogs 17 drives output shafts 19 and rotate, and the velocity ratio of this moment is greater than the velocity ratio of first kind of situation.
3) connect clutch 14 and be failure to actuate when first, and second when connecting clutch 16 actions, promptly second cog and 15 be not connected and be connected with output shaft 19 with input shaft 11.The rotation of input shaft 11 can cog by first and 13 drove first lower gear 22, second lower gear 21, the 3rd lower gear 20 and rotates simultaneously this moment, and then drove second the 15, the 3rd 17 rotations that cog that cog.Because second cogs the velocity ratio of 15 and second lower gear 21 less than the 3rd velocity ratio that cogs the 17 and the 3rd lower gear 20, therefore second cog 15 the rotating speed is higher than the 3rd and cogs and 17 rotate, under the effect of second overrunning clutch 18, output shaft 19 cogs by second and 15 has driven rotation, and the velocity ratio of this moment is greater than the velocity ratio of second kind of situation.
4) when first connects clutch 14, second and connect clutch 16 and move simultaneously, cogging this moment second 15 is connected with input shaft 11, output shaft 19 simultaneously, and this moment, input shaft 11 can directly drive output shaft 19 rotations, velocity ratio maximum.
By foregoing description as can be known, this gear driving mechanism can connect clutch 14, second by control first and connect the variation that clutch 16 actions realize 4 speed transmission ratios, and is simple in structure, is easy to realize, and this gear driving mechanism can realize multistage linking, realizes that a plurality of gear transmissions change.
As shown in Figure 2, it is the schematic representation of a gear transmission system connecting to form of two identical above-mentioned gear driving mechanisms, wherein gear driving mechanism 1 is the upper level of gear driving mechanism 2, and the output shaft 19 of gear driving mechanism 1 is the input shaft of gear driving mechanism 2.This gear transmission system can connect the speed conversion that clutch 24, second connects the gear of clutch 26 realizations 16 by first on the first connection clutch 14, the second connection clutch 16 and the control driving mechanism 2 on the control driving mechanism 1.In like manner, can finish the variation of 64 gears if this gear transmission system is made up of 3 gear driving mechanisms, by that analogy, adopt this gear transmission system of this structure can realize the variation of hundreds and thousands of gears, and simple in structure, be easy to realize.
More than a kind of gear driving mechanism and gear transmission system that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; therefore this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
