Title:
PLANETARY CHANGE GEAR
Document Type and Number:
Japanese Patent JPS62242163
Kind Code:
A
Abstract:
PURPOSE:To improve efficiency at the time of direct coupling of input/output for a planetary change gear, by constituting it with a sun gear, an internal gear, a planetary gear and a carrier or the like, and making either a turning shaft or the sun gear connected to the carrier free of thrust movement. CONSTITUTION:A sun gear 1 is installed in a turning shaft 6 being free of thrust movement as one body. And a spline 70 of a turning shaft 7 is engaged with a spline 60 with the thrust movement of the turning shaft 6. If a rod 9 is moved to the left as well as when either of both these turning shafts 6 and 7 is set down as input, decelerating output appears in the other side. However, if the rod 9 is operated and the turning shaft 6 is moved to the right, the spline 60 and the spline 70 are engaged with each other so that both these turning shafts 6 and 7 just come into a state of being directly coupled with each other while a planetary gear 2 and a carrier 3 are separated from these turning shafts 6 and 7, not to mention an internal gear 4. Therefore, an efficiency drop due to a loss of turning moment load or the like in these elements is brought to nothing.
