Patent Number Title Of Patent Date Issued
7347115 Linear actuator March 25, 2008
A rotary shaft and a rotation driven member are connected as to transmit motive power when the rotary shaft rotates relatively to the rotation driven member. A roller gets displaced to a first position where a frictional force with an outer race and the rotation driven member decreas
6908405 Pulley width adjusting device for continuously variable transmission June 21, 2005
A ball screw mechanism that can drive a movable pulley disk in an axial direction includes a screw cylinder and a nut member. A stopper pin is inserted through the screw cylinder from one end surface of the circumferential wall of the screw cylinder to the other end surface. As an en
6860827 Actuator device for manipulating movable member March 1, 2005
In an actuator device which comprises a screw shaft, a nut member, and balls, the nut member moves relatively to the screw shaft in a first axial direction and a second axial direction opposite thereto in a manner such that it is continually subjected to a load in the first axial directi
6691551 Traction coefficient measurement device February 17, 2004
The present invention provides a traction coefficient measurement device having a driving roller rotated around a driving shaft, a driven shaft is rotated together with a driven shaft, corresponding to the rotation of the driving roller, based on the engagement with the driving roller, a
6644094 Traction coefficient measurement device November 11, 2003
The present invention provides a traction coefficient measurement device having a driving roller rotated around a driving shaft, a driven shaft is rotated together with a driven shaft, corresponding to the rotation of the driving roller, based on the engagement with the driving roller, a
6260654 Frictional transmission July 17, 2001
A frictional transmission comprises first and second rotary shafts arranged in directions in which the central axes thereof crossed each other, a roller supported coaxially with the first rotary shaft for rotating with the first rotary shaft, a first frictional surface provided on the ro
5931759 Friction-roller speed changer August 3, 1999
A friction-roller speed changer has three intermediate rollers (12a, 12b, 12c). Two rollers (12a, 12b) of which act as a wedge roller and can be moved into the narrower area of an annular space (10) by the transmission of power, wherein during power transmission from the input side in th
