  • Power tool with continuously-variable transmission traction drive
    Patent number: 9186808
    Abstract: A screw-fastening tool having a continuously-variable transmission traction drive includes a continuously-variable transmission, a thrust cam mechanism of the continuously-variable transmission and a clutch plate of a fastening torque setting mechanism arranged in series between an electric motor and a spindle. A traction grease having a high traction coefficient is used as a lubricant for a traction drive. A grease reservoir or felt members in sliding contact with oppressing parts are disposed in a transmission case.
    Type: Grant

  • Power tool
    Patent number: 8564236
    Abstract: A technique for providing a user with effective information in performing an operation is provided in a power tool having a speed change mechanism. A power tool has a speed change mechanism that switches a tool bit 113 from first drive mode in which the tool bit is driven at high speed and low torque to second drive mode in which the tool bit is driven at low speed and high torque, according to load on the tool bit 113. The power tool includes detecting and indicating device 161, 163, 167 that detect a predetermined status condition of the first drive mode and indicate switching from the first drive mode to the second drive mode before switching to the second drive mode.
