Clipping is a handy way to collect important slides you want to go back to later. Looks like you’ve clipped this slide to already. through the axis of cam shaft from the following data: Follower to move outwards through 40mm during 60° of cam rotation. The least radius of cam is 50mm. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. 1. See our Privacy Policy and User Agreement for details. It is normally connected with a prime mover, which rotates it. velocity and acceleration of the follower during the outward stroke and return stroke. This means that the relative motion between them is a combination of a relative turning motion and a relative translating motion. It is a reference point on the follower and is used to generate the pitch curve. are tangential to the offset circle of 10mm dia. The cam profile is then drawn inside the envelope of these follower position.Disk Cam with Reciprocating Roller FollowerThe cam is to rotate clockwise, while the follower moves according to the scale on its center line. The shape of the cam is called the PROFILE. Trace point. Cam Profile Camshaft Basics. Course Hero is not sponsored or endorsed by any college or university. It is the smallest circle that can be drawn to the cam profile. 1. Hence the, first step in constructing the cam profile is to draw the displacement diagram according to the, desired motion of follower. The cam is supposed to, remain fixed while the line of stroke of the follower is revolved round the cam in the opposite, direction to that in which the cam actually turns on its axis. The camshaft is your engine's "mechanical computer". By providing Pre-Construction, Cost Estimating, Design-Build, Construction Management, and General Contracting services, our staff continues to serve the Maryland community, as well as select projects along the East Coast. I found it only on a video on youtube after hours of searching but without any code or even a description if it can be done on matlab or not.

The base circle passes throughthe axis of the roller when the follower is its lowest position.The distance from the point of the follower in its lowest position to the center of rotation of the cam is the radius of the basecircle. It controls the opening and closing of the valves which is critical to how your engine will operate. You can change your ad preferences anytime. The shape of cam profile is obtained from the displacement diagram of the follower. 2. If you continue browsing the site, you agree to the use of cookies on this website.

Hence the first step in constructing the cam profile is to draw the displacement diagram according to the desired motion of follower.

Construction of Cam ProfileThe shape of the profile will depend on the size of the cam and the size, shape and path of the follower. broad cam nose), the transition between the three phases, for an object sliding on the cam’s surface is very smooth. shows a radial cam with reciprocating roller follower. The cam shown is a pear shaped cam (named after its shape). When laying out thecam profile, the principle of inversion is used. Search by company name, city, keyword, or specialty. When laying out thecam profile, the principle of inversion is used. With the cam held fixed, the frame and the follower are rotated around the cam tobring the contact surface of the follower on its actual position relative to the cam for a large number of phases of themechanism. Cam Follower Design Terminologies. The following terms are important in order to draw the cam profile. The cam is supposed to remain fixed while the line of stroke of the follower is revolved round the cam … Cam profile: Construction is same as previous case, except that the lines drawn from 1,2,3…. 1 CAM PROFILE CONSTRUCTION. Follower to return to its original position during next 90°. If you continue browsing the site, you agree to the use of cookies on this website. This preview shows page 1 - 2 out of 4 pages. my deadline is approaching so please help me to get this done. CAM PROFILE CONSTRUCTION.pdf - CAM PROFILE CONSTRUCTION The shape of cam profile is obtained from the displacement diagram of the follower Hence the, The shape of cam profile is obtained from the displacement diagram of the follower. Terms Used in Radial Cams • Fig. CAM PROFILES : Cams can be shaped in any number of ways and this is determined by the way the follower is to move. The profile of the contact surfaces of, the follower with the cam for the successive positions of the follower gives the actual profile of, Draw the profile of a cam operating a knife-edge follower when the axis of the follower passes. (2) Draw the cam profile for the same operating conditions of problem (1), with the follower off set by 10 mm to the left of cam center. Examples of various cam profiles can be seen below. Welcome to the official mobile application for the Construction Association of Michigan (CAM)! Now customize the name of a clipboard to store your clips. Follower to dwell for the rest of the cam rotation. Construction of Cam ProfileThe shape of the profile will depend on the size of the cam and the size, shape and path of the follower. Follower**:** With the rotation of the cam, the follower (the shaft with the roller at bottom in the above picture) gets oscillated or translated according to the profile of the cam. If the cam rotates at 300 rpm, determine the maximum. The modified cycloidal cam profile is also a three-phase D-R-R-D cam that has a distinguishable characteristic, which makes it ideal for use in high-speed machinery (Reeve, 1997).Owing to the broad nature of the cam’s geometry (i.e. Now the actual conditions are reversed. CAM Construction is a privately owned construction service firm, based in Baltimore Maryland, since 1962. as shown in the fig. thank you Hareesha N Gowda, Dayananda Sagar College of Engg, Bangalore, No public clipboards found for this slide. I have a home-project to develop linear cam profile with roller follower In the way that appear in the picture. We possess more than a half … Now the actual conditions are reversed. Cam profile design principle: The method termed inversion is commonly used in cam profile design. The displacement of the follower is to take place with SHM during both outward and the return, strokes. Laid off along the follower are the ordinates from each position along θ axis of the displacement diagram. 1. Cam**:** The cam is the driver.
