Cams Patents (Class 74/567)
  • Patent number: 9651133
    Abstract: The present disclosure relates to a system that uses linear actuators to generate a torque on a shaft. In an example implementation, a system may include a shaft and an attached cam. The cam includes an involute portion. The system also includes a first linear actuator and a second linear actuator configured to move along a first axis and a second axis, respectively. The linear actuators are configured to detachably couple to the cam based on at least a reference angle of the shaft. That is, as the shaft rotates about its rotational axis at the reference angle, the first and the second linear actuators may couple to, and decouple from, various portions of the cam. As the linear actuators couple to, and decouple from, the various portions of the cam, different rotational torques and/or different ranges of such torques may be imparted onto the shaft.

    Abstract: A cam shaft is disclosed having an asymmetric chamfer for guiding a ball bearing deeper into a cam shaft groove to avoid ball loss when an immediate deceleration force is applied. The chamfer spaces the ball from an opening in the front face of a hammer that moves axially relative to the cam shaft when a tool having the cam shaft and hammer is dropped. The ball is therefore less likely to escape through the front opening of the hammer when the impact wrench is dropped.

  • Patent number: 8881620
    Abstract: A hydraulic operated valve includes an electromagnetic adsorption mechanism and a steel ball. In the electromagnetic adsorption mechanism, when a current is supplied, an adsorption plate is adsorbed by a solenoid. By this adsorption, a steel ball is pressed against an outer surface of a cam disc. The outer surface of the cam disc includes two steps. When the cam disc is rotated clockwise or counterclockwise, the pressed steel ball engages the two steps. Thus, the cam disc is detented. These two steps are configured such that when the cam disc is returned to a neutral position, the adsorption plate is separated from the solenoid against the pressing of the electromagnetic adsorption mechanism. Thus, the detent state of the cam disc is canceled.

    Abstract: A driving device has a driving cam driven by a motor around a cam shaft, a roller which is in contact with the driving cam, a supporting frame, and a control shaft. The driving cam has a pocket portion. At the pocket portion, a profile distance from a center increases or decreases when the driving cam rotates in a normal direction or a reverse direction. When the pocket portion is in contact with the roller and the motor is stopped, the rotational force of the driving cam becomes zero. The rotational position of the driving cam and the axial position of the control shaft are held at a constant position. Thereby, the rotary place of the driving cam and the axial position of the control shaft component can be held in a fixed position.

  • Patent number: 8668466
    Abstract: A variable displacement reciprocating pump with pumping rate that is adjustable from zero to maximum stroke while the pump is running. Stroke is varied by changing relative position of pairs of eccentric inner and outer cams that drive the pump's plungers. The pump's input drive shaft drives two gear trains: a first gear train that turns the inner cams and a second gear train that turns the outer cams. These cams normally revolve together with no relative motion occurring between them. A rotary actuator is positioned in the first gear train to rotate the inner cams relative to the outer cams and thereby changes the pump's stroke. A computerized system of sensors and control valves allows the pump to be automatically controlled or limited to any one or combination of desired output flow, pressure and horsepower.

  • Publication number: 20140041984
    Abstract: The pivot control mechanism that selectively controls the rotation of the pivot control shaft by an electric impulse from the solenoid, which locks the pawl into the ratchet, thereby permitting the shaft to rotate in a selected direction. When a passage direction is chosen, the cam followers move out of the home position of the lofted ratchet over the peak position to the next home position. The guiding pins controlling the axial motion of the lofted ratchet in conjunction with the compression springs secure the cam followers in the home position. The shock absorber acting on the cam is used to prevent the turnstile from over rotating with any great amount of force, hence softening the return of the cam followers to the home position. The micro switch is activated, sending a signal to the control board, which through the action of the solenoid, locks the pawls into the ratchet.

  • Patent number: 8627734
    Abstract: A prestressing unit which has a first ramp disk and a second ramp disk. Ramp contours are formed in one side of an annular face of the ramp disks. In the prestressing unit, the rolling bodies ascend and/or descend on the ramp contours as a result of rotational pivoting of one of the ramp disks in relation to the other ramp disk about an axis. The ramp contours are each formed as a single-part running face for the rolling bodies. The running face is inclined with respect to the axis.

  • Publication number: 20130333514
    Abstract: A compliant cam system includes a cam having a cam body rotatable with respect to a cam rotational axis. The cam body has a cam body center spaced from the cam rotational axis. At least a portion of the cam is an elastically compressible material. A follower having at least one follower surface is in contact with the compressible material portion of the cam. A cam non-deflected condition is defined when an elastically compressible material portion outer surface is in contact with the cam follower surface prior to deflection of the elastically compressible material portion. The cam when thereafter rotated with respect to the cam rotational axis moves the cam body center toward the follower. The elastically compressible material portion deflects, defining a deflected condition, creating a biasing force acting toward the follower, and releasably frictionally engaging the elastically compressible material portion with the follower.

  • Publication number: 20130269474
    Abstract: The invention relates to a camshaft for a small internal combustion engine used in for example cars or motorbikes, it is characterized by being divided into two or more components, preferably it is the camshaft bearing journals (3) on the camshaft that are separate components. With a camshaft in one piece the camshaft lobes (4) cannot have a larger radius than the camshaft bearing journals (3) if the camshaft is to be inserted through the camshaft support bearings (2) in the engine. The bearing journals (3) will then limit the design and height of the camshaft lobes (4). By designing the camshaft divided in separate components to be assembled at the same time or after the camshaft has been inserted into the engine, it is possible to insert the camshaft radially displaced through the camshaft support bearings (2). This makes it possible to design the camshaft lobes (4) larger than what would otherwise be possible for given dimension of the support bearings (2).
