    Abstract: An eccentric speed variator includes a first rotor, a second rotor, a third rotor, a cylindrical pin, and a flange. The second rotor has a hole formed therein. The third rotor rotates eccentrically to change a relative rotation phase between the first and second rotors. The cylindrical pin extends through the hole of the second rotor to establish mechanical engagement between the second and third rotors. The flange is secured to or integrally formed with an end of the cylindrical pin. In operation, when the flange contacts the outside wall of the second rotor, it serves to minimize inclination of the third rotor relative to the second rotor, thereby reducing local friction between the second and third rotors to eliminate undesirable mechanical vibration or noise. This structure also enables parts of the cycloidal speed reducer to be decreased, which leads to a reduced size of the cycloidal speed reducer.

    Abstract: A first slip travel mode is traveling or starting in a state where a first clutch is fully connected and a third clutch is fully disconnected while a second clutch is slipped. A second slip travel mode is traveling or starting in a state where the first clutch is fully connected and the second clutch is fully disconnected while the third clutch is slipped. An overheat avoidance mode is traveling or starting in a state where the first clutch is fully disconnected and the second clutch is fully connected while the third clutch is slipped. When the second clutch is in a high-temperature state under the first slip travel mode or the third clutch is in a high-temperature state under the second slip travel mode, the slip travel mode is switched into the overheat avoidance mode. This reduces a heat value of the second clutch or third clutch.

    Abstract: A joint includes a rotation transmitting portion and a stopper portion. The rotation transmitting portion abuts on a relative rotating portion in a circumferential direction. The stopper portion is capable of abutting on the relative rotating portion to restrict an axial position of the relative rotating portion. The stopper portion of the joint which rotates at the same speed as the relative rotating portion restricts an axial position of the relative rotating portion, whereby a sliding movement does not occur between the relative rotating portion and the stopper portion. It can be restricted that a power transmission efficiency is decreased and an abrasive wear is generated.

    Abstract: An eccentric oscillating speed reducer includes an input rotor, a first rotor, a second rotor, a planetary rotor, a flow passage, a contact portion and a radial relief groove. The flow passage includes an axial gap located between the planetary rotor and a contact member. The flow passage conducts a lubricant oil that is forced to flow by a centrifugal force. The contact portion is placed in a drive force transmission path from the planetary rotor to the second rotor. The contact portion includes: a planetary rotor end surface of the planetary rotor located on a side where the second rotor is placed; and a second rotor end surface of the second rotor, which is opposed to the planetary rotor end surface. The radial relief groove forms a portion of the flow passage and extends through a radial width of the planetary rotor end surface.

    Abstract: A power transmission system transmits power from a drive shaft of an internal combustion engine to a first and a second auxiliary device through a belt. An auto-tensioner extends or contracts to change the tension of the belt. A controller rotates the first auxiliary device in a reverse direction to loosen the belt to cause the auto-tensioner to extend to increase the tension of the belt and calculates a reversing timing when the drive shaft will be reversed as a result of increasing of the tension of the belt. The controller inhibits the tensioner body from contracting immediately before or when the reversing time is reached to keep the tension of the belt at an increased degree, thereby eliminating the slippage of the belt on each pulley without having to finely control the operation of the first auxiliary device when the internal combustion engine is started.
