Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of transmission box for tiller, comprise casing 1, in casing 1, be provided with power shaft 3 with duplex-gear 2, with fast gear tooth 4 and keep off slowly the countershaft 6 of tooth 5, with the I axle 10 of the tooth 7 that reverses gear, I level tooth 8 and driving cog 9 with the output shaft 12 of output gear 11, end at described countershaft 6 is provided with the countershaft tooth 13 that is integrated with countershaft 6, described countershaft tooth 13 and driving cog 9 engagements mesh by gear between described I level tooth 8 and the output gear 11.
Further, be provided with the II level tooth 14 with I level tooth 8 engagement in described casing 1, described II level tooth 14 is by III level tooth 15 and output gear 11 engagements, and described II level tooth 14, III level tooth 15 are connected with the III axle by II axle 16 respectively and are connected with casing 1.
In the utility model, the power transmission route is such:
Fast gear: power shaft 3-duplex-gear gear wheel-keep off soon tooth 4-countershaft 6-countershaft tooth 13-driving cog 9-I axle 10-I level tooth 8-II level tooth 14-III level tooth 15-output gear 11-output shaft 12;
Slowly gear: power shaft 3-duplex-gear gear wheel-keep off slowly tooth 5-countershaft 6-countershaft tooth 13-driving cog 9-I axle 10-I level tooth 8-II level tooth 14-III level tooth 15-output gear 11-output shaft 12;
Reverse gear: the power shaft 3-duplex-gear canine tooth-tooth canine tooth that the reverses gear-little tooth of the tooth that reverses gear-keep off soon tooth 4-countershaft 6-countershaft tooth 13-driving cog 9-I axle 10-I level tooth 8-II level tooth 14-III level tooth 15-output gear 11-output shaft 12.
In the utility model, the modulus of described each gear and the number of teeth are:
Proportioning by said gear:
Fast gear rotating speed:
n=3600×45/106×28/36×12/52×17/45=103.6r/min；
Slowly keep off rotating speed:
n=3600×45/106×14/50×12/52×17/45=37.3?r/min
Wherein, the rotating speed of fast gear can offer rotary tillage cutter and carry out rotary tillage, when keeping off slowly, rotary tillage cutter is replaced by plough, and the rotating speed of gear just can offer plough so slowly, carries out ploughing, reaches the purpose of dual-use.
