What is considered a small base circle cam?
These required what is called a small, or . 900-inch base circle cam.
What does a circle cam do?
Circular cams use an off-centre pivot to cause the follower to move up and down. The follower will rise and fall by a reasonably large amount. These can be seen in pistons, for example on steam engines.
What is throw cam?
Stroke or throw: The greatest distance or angle through which the follower moves or rotates. It is the maximum distance of followers from the base circle. It is the smallest circle of a cam profile drawn from the center of rotation of the cam.
What is cam short for?
Cam is both a given name and a surname, often a shorthand for Cameron or Camilla (given name).
What is dwell period of cam?
Rise is the motion of the follower away from the cam center, dwell is the motion during which the follower is at rest; and return is the motion of the follower toward the cam center. There are many follower motions that can be used for the rises and the returns.
Which type of cam is used for high speed engine?
Explanation: Cycloidal motion curve has the best dynamic characteristics. The acceleration is finite at all times and the starting and ending acceleration is zero. It will yield a cam mechanism with the lowest vibration, stress, noise and shock characteristics.
What is a radial cam?
A radial cam converts a rotational motion into a translational motion of the follower. The displacement of the follower is determined by the cam’s profile. For smooth operation, they must be continuous and finite across the entire range of the cam angle.
What does Cameron mean girl?
The name Cameron is a girl’s name of Scottish origin meaning “crooked nose”.
What is a small base circle Cam?
These required what is called a small, or .900-inch base circle cam. Cam lifts on these rollers was around .420 inch with a 104 to 106 lobe separation angle. I bring up the cam specs to serve as a base for why I think things are as they are today, and how exact terms came to be generic terms when discussing base circle.
What happens if you reduce the base circle on a Chevy?
These apply to a 1.868-inch, standard journal Small Block Chevrolet. In terms of clearing the connecting rod, the actual base circle is not what interferes with the rod. It is the flank/nose, peak lobe lift area that is of concern. Shrinking the base circle pulls this point away from the rods.
What size is the base circle on a Chevy small block?
These apply to a 1.868-inch, standard journal Small Block Chevrolet. In terms of clearing the connecting rod, the actual base circle is not what interferes with the rod. It is the flank/nose, peak lobe lift area that is of concern.
Should I shrink the base circle of my rods?
Shrinking the base circle pulls this point away from the rods. There are a lot of options out there that will allow not having to sacrifice base circle. Most, if not all, of the connecting rod manufacturers offer a “stroker” rod. These will already have the shoulder of the rod clearanced to clear a standard base circle cam.
