Conical Sleeve Patents (Class 279/62)
  • Patent number: 10883572
    Abstract: A cycloid speed reducer has a housing for accommodating a piece of equipment. Outer pins in meshing engagement with cycloid gears of a reduction gear portion are incorporated into the housing as a sliding bearing. A lubrication ring for lubricating the outer pins is slidably incorporated into the housing. The outer pins are lubricated by the outer pin lubricating ring. Inner pins are lubricated by a lubricating ring. The pair of cycloid gears are lubricated via the outer pins and the inner pins. As a result, friction between components is reduced, whereby frictional resistance decreases and durability is enhanced. In addition, the cycloid speed reducer can be manufactured as a small, compact unit.

Each element includes a pair of parallel arms connected to the tool bar bracket forming a parallel linkage for up and down movement of a support arm connected at a rear end and carrying the packer wheel. A spring applies a downward spring force on the parallel linkage to apply a downward force on the packer wheel so that the spring force increases as the parallel arms pivot upwardly and decreases as the parallel arms pivot downwardly. A control device is arranged to raise and lower the tool bar in response to a detected value of a sensor so as to change the angle of the parallel linkage and change the spring force. A cam controlled double rack adjustment of the height of the opener allows the user to change seeding depth.

    Abstract: A chuck including a body with a nose section defining an axial bore formed therein, a plurality of jaws movably disposed with respect to the body, and a sleeve rotatably mounted about the body so that rotation of the sleeve moves the jaws relative to the axial bore. A bearing has a first race, a second race, and at least one bearing element disposed therebetween, one of the first race and the second race defining a ratchet and the other defining a pawl biased toward the ratchet. A biasing element is disposed between the pawl and the sleeve. The biasing element exerts a biasing force on the pawl toward the ratchet and the ratchet and the pawl prevent the second race from rotating in the opening direction with respect to the first race when engaged.

  • Patent number: 8387995
    Abstract: A chuck for use with a driver, the chuck including a body having a nose section defining an axial bore and a tail section. A plurality of jaws is in communication with the axial bore. A first sleeve is rotatably mounted to the body so that rotation of the sleeve moves the jaws either toward or away from a longitudinal center axis of the axial bore. A second sleeve is rotatably mounted to the body and is movable between a first position in which the second sleeve is rotatably fixed to the body and a second position in which the second sleeve is rotatable about the body. The second sleeve moves in a direction transverse to the longitudinal center axis of the axial bore when moving between the first position and the second position.

  • Patent number: 8371779
    Abstract: A chuck including a body having a tail section defining an annular shoulder and a nose section having an axial bore and angularly disposed passageways intersecting the axial bore. An O-ring is disposed in the annular shoulder and a plurality of jaws is slidably positioned in the passageways. A nut is rotatably mounted on the body in engagement with threads on the jaws. A first sleeve and a second sleeve each define a gripping surface thereon and one of the first and second sleeves is axially reciprocal on the body. The one of the first and second sleeves defines an annular groove on an inner surface thereof having a first shoulder and a second shoulder. The O-ring is received in the groove such that axial motion of the one of the first and the second sleeve is limited by abutment of the O-ring with said first and second shoulders.

  • Patent number: 8061719
    Abstract: A drill chuck has a chuck body centered on and rotatable about an axis and formed with angled guides and respective jaws slidable in the guides axially forward and radially toward each other and axially rearward and radially away from each other. An annular tightening element is limitedly axially shiftable on the sleeve between a front position and a rear position. Screwthreads engaged between the element and the jaws axially displace the jaws forward on rotation of the element in a tightening direction and axially displace the jaws rearward on rotation of the element in an opposite loosening direction. Respective annular arrays of teeth angularly fixed on the element and the body are interengaged and prevent relative rotation of the element and body in the rear position of the element and are spaced and permit relative rotation of the element and body in the front position of the element.
