The planetary gear speed reducing mechanism has a driving-side member that is rotationally driven by a prime mover, a driven-side member which is rotatably and coaxially disposed with the driving-side member and to which a tool bit is coupled, and an intervening member which is disposed between the driving-side member and the driven-side member. The intervening member is configured as a planetary member and at least caused to rotate by frictional force acting on its contact surface in contact with the driving-side member when the driving-side member is rotationally driven, so that torque of the driving-side member is transmitted to the driven-side member at reduced speed.

  • Patent number: 9388342
    Abstract: An electric actuator is provided for operating an unheading valve of a coke drum. The electric actuator includes a driving element comprising a planetary roller screw for actuating the unheading valve. By using a planetary roller screw, rather than hydraulics for the driving element, the electric actuator of the present invention can be used in place of hydraulic actuators while still providing sufficient power and reliability for use with an unheading valves of a coke drum.

  • Patent number: 9303741
    Abstract: The linear-to-rotary actuator includes an elongated drive member constrained to linear movement, and a rotary member constrained to rotary movement. The elongated drive member has a coupling end and an engaging member that projects from the coupling end. The rotary member has a track defining an Archimedean spiral. The track is adapted to receive the engaging member. The engaging member is constrained to slide in the track such that linear movement of the elongated member effects rotation of the rotary member. The track may be a slot, a groove, or other guide. Alternatively, instead of a track defined directly in the rotary member, the actuator may include a linking member (such as a disk or rectangular bracket) attached to the rotary member, the linking member having a track defining an Archimedean spiral defined therein, the engaging member being slidable in the track to convert linear motion into rotary motion.

  • Publication number: 20150107385
    Abstract: A casing running tool is connected to a top drive with a clutch that operates with set down weight against a spring resistive force. Setting down weight with rotation in a first direction raises an actuation member that pushes the slips out radially. The weight of the string then keeps the slips in position so that the string can be picked up and the rig floor slips removed followed by lowering the string while circulating and rotating. With slips set inside the joint and the string hanging free, rotating the top drive rotates the string as the string is lowered. With slips again supporting the string on the rig floor the top drive can be rotated in an opposed direction with weight set down to back off the slips and to remove it from the top joint.

    Abstract: The present invention describes a baby carrier rocking device. In one embodiment, the device includes a housing with an imbedded motor, MP3 player, and related components. The housing may feature various shapes and designs, and comprises an aperture at the top portion thereof. The aperture is adapted to hold a first end of an elongated arm therein. The second end of the elongated arm is adapted to rock a baby carrier. In operation, the motor actuates the elongated arm so that it extends upward at a regular interval, contacting a baby carrier and thereby pushing the same in a rocking motion. Each time the elongated arm is extended upward, it falls back down via gravity. In this way, the present invention provides parents or caregivers with a hands-free way to rock a baby carrier.
