TRACTION POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2016080064
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve concentricity of an internal ring to a second rotor including planetary rollers with a simple structure.SOLUTION: A first rotor 3 comprises a first rotating shaft part 31 and a sun roller 33. A second rotor 4 comprises: plural planetary rollers 43 that are arranged in the circumference direction and have respective outer peripheral surfaces contacting with the outer peripheral surface of the sun gear 33 and the inner peripheral surface of an internal ring 5; a planetary carrier part 42 rotatably supporting the plural planetary rollers 43 around a planetary center axis; and a second rotating shaft part 41 connected to the planetary carrier part 42. Utilizing elastic deformation of the internal ring 5, the plural planetary rollers 43 are pressed toward the sun roller 33. A mounting inner peripheral surface of the internal ring 5 is fixed to the outer peripheral surfaces of ring fixation bearings 24, 25, each of which is either a bearing supporting the first rotor 3 or the second rotor 4 relative to a casing 2.SELECTED DRAWING: Figure 1
