Title:
PLANETARY GEAR TYPE SPEED CHANGE MECHANISM
Document Type and Number:
Japanese Patent JP3569953
Kind Code:
B2
Abstract:
PURPOSE: To provide a speed change mechanism having a simple structure by making the axes of rotation and displacement shafts into concentric and eccentric conditions to cause the change of a transmission velocity ratio to determine a place high in the angular velocity of the displacement shaft by using a one-way transmission mechanism by a joint mechanism.
CONSTITUTION: Plural displacement shafts 14 are rotatably arranged on an adjustment member 9 concentrically rotating with an output shaft 3. A gear-to-be-transmitted 16 engaging with a speed change gear 6 is arranged via a one-way transmission mechanism 17 onto respective displacement shafts 14, and plural rotation shafts 18 rotating by an arm member A are arranged opposite to the displacement shafts 14. Moreover, a joint mechanism 19, wherein a transmission velocity ratio is momentarily changed in one rotation at the time of shaft axis displacement with each other, is provided with a rotation phase displaced each other between the rotation and displacement shafts 18 and 14. The rotational frequency of the inscribed gear B of a planetary gear mechanism can be changed to change the velocity ratio between an input shaft 2 and the output shaft 3, by determining a place high in an angular velocity caused in the respective displacement shafts 14 by using the one-way transmission mechanism 17. Rotation can be surely transmitted to the inscribed gear B to perform good speed changing.
