31 be engagement internal tooth, and the second meshing gear 42 is engagement external tooth.
When number of teeth difference is 1, its gear ratio is calculated as follows：
i=360/(360/Z1-360/Z2)
Wherein, i is gear ratio, Z1For the number of teeth of the second meshing gear 42, Z2To engage the number of teeth of internal tooth 21, Z3For engagement external tooth
41 number of teeth, Z4For the number of teeth of the first meshing gear 31.
For example：Z1=21, Z2=36, Z3=35, Z4(360/21-360/36) ≈ 50.4 of=20, i=360/.
The output of embodiment two uses internal tooth engagement output, and the output of embodiment one uses external tooth engagement
Output, embodiment two is for embodiment one, and the arm of force that embodiment two is exported is more than what embodiment one was exported
The arm of force, therefore the torque that embodiment two is exported is more than the torque that embodiment one is exported, so the torsion that embodiment two is exported
The torsion exported more than embodiment one.
During present invention operation, the high speed rotation of engine is inputted by power input shaft 1, the driving driving cog of off-centre operation ring set 11
Disk 4 is moved, because housing 2 is fixed, and effect of the engagement external tooth 41 with engaging the engagement of the few teeth difference of internal tooth 21 forces transmission fluted disc 4
The rotation opposite with the input direction of power input shaft 1 is produced, and because of the second meshing gear 42 and the few teeth difference of the first meshing gear 31
The effect of engagement, so as to be driven the low speed rotation that the driving power output shaft 3 of fluted disc 4 completes decelerator.
It is an advantage of the current invention that the present invention is inputted using by the high speed rotation of engine by power input shaft 1, off-centre operation
The driving transmission fluted disc 4 of ring set 11 is moved, and because housing 2 is fixed, engagement external tooth 41 is with engaging the engagement of the few teeth difference of internal tooth 21
Effect forces transmission fluted disc 4 to produce the rotation opposite with the input direction of power input shaft 1, and because of the second meshing gear 42 and first
The effect of the few teeth difference of meshing gear 31 engagement, so as to be driven the low speed rotation that the driving power output shaft 3 of fluted disc 4 completes decelerator.
Reducer structure of the invention is simple, cost is low, can realize big gear ratio, and solving traditional decelerator big speed ratio needs substantially
Long-pending technical problem, realizes big gearratio in the speed changer of small size, and big deceleration effect will be reached by solving in small space
The problem of fruit.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
