Title: Planetary roller speed changer
Inventor: NAITO HAYAO
IPC: F16H13/08
Filed: 2001-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a planetary roller speed changer, causing almost no wear of a planetary roller, a sun roller and a fixed wheel even in applications where reversing motion is repeated, therefore eliminating the need for using a larger capacity of gear changer than conventionally required in such applications and contributing to downsizing of a device. SOLUTION: An output-side element out of the sun roller 1 and a carrier 6 has an output shaft 8 formed as a separate member and a damper member 10 is laid between the output shaft 8 and the output-side element (for example, the carrier 6). Thus, right after starting or reversing, the planetary roller 5 starts rolling, while the rotation of the carrier 6 is not transmitted to the output shaft 8 because the rotation is absorbed by the damper member 10, almost no torque load of toque occurs and substantial rotating power is transmitted after rotation to some extent.  As a result, right after starting or reversing, the planetary roller 5 is rolled in the state of almost no torque load to form a fluid film and substantial rotating power is transmitted in the state of forming the fluid film, therefore producing the least possible wear of each element resulting from the runout of the fluid film.
