  • Patent number: 10968900
    Abstract: A positive displacement pump for pumping a fluid mastic comprises a plurality of cylinders each having a piston arranged for reciprocal motion within the cylinder. Movement of the piston in a first direction draws the fluid into the cylinder and movement in a second, opposite direction pumps the fluid out of the cylinder. A variable speed electric motor is drivingly coupled to a cam arrangement providing a reciprocating drive to the pistons. The cam arrangement comprises cams shaped and arranged to drive each piston in the first direction over less than half of a rotational cycle and to drive each piston in the second direction over the remainder of the rotational cycle. The cams are arranged to drive the pistons out of phase with one another.

  • Patent number: 10710229
    Abstract: A hydraulic, pneumatic, gasoline, diesel, or electric tool may include a spindle that is adapted for rotational movement. A swing arm may be coupled to the spindle such that rotational motion of the spindle is transferred to the swing arm. The swing arm makes contact with a piston such that the rotational motion causes the piston to move along a linear path. The piston may interact with an energy storage medium when the swing arm moves the piston in the first direction, causing energy to be stored in the energy storage medium. As the swing arm continues to rotate, the swing arm may lose contact with the piston, thus allowing the energy storage medium to urge the piston in a second direction opposite the first direction to strike an anvil. The swing arm may be a multiple roller swing arm. The energy storage medium may be a compound spring assembly.

  • Patent number: 10443694
    Abstract: A pair of spaced-apart cam disks disposed along a common power shaft, with a pair of cam followers disposed within channels formed in opposing inner surfaces of the cam disks, forms a balanced arrangement for creating linear reciprocating motion from the rotation of the pair of cam disks. A linear motion shaft is coupled to the cam followers. As the cam disks synchronously rotate and the cam followers trace the path formed by the paired channels, this rotational motion is converted into linear, reciprocal motion that provides the translational movement of the linear motion shaft.

The mountings may be equipped with a moulding establishing the predetermined angle position of the respective function element corresponding to the angle position on the shaft. The mountings may be positioned such that the recesses of the function elements lie on a common straight line. The mountings may be arranged vertically on top of one another so that the common straight line runs in vertical direction. A vertically moveable guide carriage for the shaft may be provided for joining the shaft with the function elements in vertical direction.

  • Publication number: 20140144259
    Abstract: An actuator that causes a mode clutch to shift between an engaged position and a disengaged position is provided. The actuator comprises a motor having an output. A shift cam is caused to rotate based on the output of the motor. The shift cam has a cam profile surface. A cam follower rides along the cam profile surface upon rotation of the shift cam. Movement of the cam follower causes movement of a mode fork resulting in the mode clutch shifting between the engaged and disengaged positions. A sensor outputs a voltage to a controller based on a physical location of the cam follower. The controller activates the motor based on the voltage.

  • Publication number: 20140137675
    Abstract: A drive cam is rotated about a camshaft member upon application a drive torque of a drive source to the drive cam. A transmission device converts rotational motion of the drive cam into linear reciprocating motion and transmits the converted linear reciprocating motion to a control shaft member. The control shaft member is connected to a controlled subject and is linearly reciprocated together with the transmission device in an axial direction. A reverse input cutoff clutch transmits the drive torque, which is received from the drive source, to the drive cam. The reverse input cutoff clutch non-rotatably locks an output shaft of the drive source in response to a reverser input torque transmitted from the controlled subject through the drive cam.

    Abstract: Infinitely variable motion control (IVMC) provides motion control without any requirement for changing gears or use of a clutch. A spur gear transgear, defined as a system having an input, an output and a control, a variable pitch cam having an eccentric inner and outer cam assembly and a driver may be used to form a speed converter. The speed converter is used in various forms to provide an infinitely variable transmission, a differential, embodiments of wind and river turbines and pumps/compressors. In one embodiment, the speed converter drives first and second directional control assemblies to provide a vehicle with zero turn radius. Various embodiments of an infinitely variable pump or compressor are described.

  • Patent number: 8720162
    Abstract: A motor-driven machine tool comprises a tool driven in a rotating fashion, a drive shaft driven by a drive unit and an output shaft for holding the tool. According to the invention, the rotating motion of the drive shaft can be transferred to the output shaft by way of an eccentric coupling device. A mass balancing device is provided for smoothing out vibrations, which has a stroking mass part moveably mounted in a carriage guide and impinged by an eccentric member driven by one of the shafts. The stroking mass part executes a rotary smoothing motion.

  • Patent number: 8714038
    Abstract: A tool has a flange attached to an engine housing. A primary cam is rotated to advance segments into the housing and a second rotational cam causes the segments to turn relative to each other as they are being inserted into the housing. This causes the segments to follow a predetermined path as they extend into the housing to bring a sensor at the end of the segments into a sensing position.
