Title:
LINEAR GEAR CHANGE POWER TRANSMISSION MECHANISM
Document Type and Number:
Japanese Patent JP2017089737
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a linear gear change power transmission mechanism having a simple and small-sized structure, showing less transmission loss and preventing occurrence of jerk when the gear change is carried out.SOLUTION: A linear gear change power transmission mechanism comprises a transmission part 1, a power input holding ring body 2, a power output holding ring body, two first ball ring bodies 4, a power input rotary body 5, a power output rotary body 6 and two helical elastic bodies 7. The transmission part 1 has a supporting rotor 14, a plurality of transmission balls 13 and a plurality of driving disc levers 12. The transmission balls 13 are arranged at the supporting rotor 14 while being spaced apart and movable. Each of the transmission balls 13 has a column-like storing part 131 arranged in a radial direction. An inner end of each of the driving disc levers 12 is movably arranged at the column-like storing part along a radial direction of the supporting rotor 14. The supporting rotor 14 is eccentrically rotated by the driving disc levers 12.SELECTED DRAWING: Figure 1
