cam to linear motion

  • Basics of cam followers (including those for linear motion)

    May 15, 2019· Many cam followers have flat outer diameter (OD) profiles, while others (especially those for linear-motion applications) include crowned, edge-flanged, or vee-shaped ODs to engage tracks and rails that are engineered with mating geometry. A cylindrical cam or barrel cam is a cam in which the follower rides on the surface of a cylinder. In the most common type, the follower rides in a groove cut into the surface of a cylinder. These cams are principally used to convert rotational motion to linear motion …

  • Eccentric (mechanism) - Wikipedia

    In mechanical engineering, an eccentric is a circular disk (eccentric sheave) solidly fixed to a rotating axle with its centre offset from that of the axle (hence the word "eccentric", out of the centre).. It is used most often in steam engines, and used to convert rotary into linear reciprocating motion to drive a sliding valve or pump ram. To do so, an eccentric usually has a groove at its ...

    Linear motion products are used in conveyors and assembly operations to provide movement in a straight line, including rolling elements in a raceway or guide rail. They also keep parts and machinery moving and aligned. Movement can be forward or backward and either vertical or horizontal. Actuators, ball screws, and nuts convert rotating ... The characteristics of the linear motion are dictated by the shape of the cam and the cam follower. The profile of the cam can be altered to achieve different characteristics in the overall mechanism. For example: Frequency: Cams are usually fairly small which helps to accomplish more rapid reciprocating motion.

  • Machine Design 101: Cam and Roller | The Short Sleeve Club

    Jan 30, 2017· There are radial cams, which translate motion along one axis, and even cylindrical cams that can translate motion along 2-axis. The roller, sometimes called a follower, is the piece that follows along with the cam's motion, and it is typically restricted to a strictly linear field of motion. This angle is important in cam design because it represents the steepness of the cam profile. 6.4 Motion events. When the cam turns through one motion cycle, the follower executes a series of events consisting of rises, dwells and returns. Rise is the motion of the follower away from the cam center, dwell is the motion during which the follower ...

  • Camshaft - Energy Education

    A cam, in its simplest definition, is a mechanical link that converts rotational motion into linear motion, or vice versa. The cams on a camshaft achieve this displacement by the rotation of a radial pattern, and a follower which moves perpendicular to the rotational axis. The cam pattern on a camshaft is non-circular with a single lobe. Most cams are used to convert rotary motion into reciprocating motion. Some convert linear motion into reciprocating motion and a few convert rotary motion into oscillating motion or reciprocating. This output motion is achieved through the use of a follower. As the cam turns, driven by the circular motion, the cam
