Friction reducer and silent electric cylinder

Abstract

The utility model discloses a kind of friction reducer and mute electric cylinder, friction reducer includes the planet disc with several bearing columns;Bearing, at least one bearing rotatably is sleeved on bearing column;Pressing plate, the top end of bearing column is installed with the pressing plate parallel with planet disc;Transmission assembly, transmission assembly is coaxially assembled with planet disc along the axis of planet disc, transmission assembly and bearing friction transmission;Outer ring, outer ring is sleeved on the outside of planet disc, and the inner wall of outer ring and the outer wall of bearing friction transmission;The end surface of pressing plate and bearing is resisted, so that bearing keeps parallel in movement process, the problem that the uneven stress of the contact of bearing and reducer outer ring is solved by the above structural design when rotating, and the uneven friction stress point of outer ring leads to the inner wall of outer ring presents horn shape, affect the service life of friction reducer.
