Cam Follower Design Terminologies. Although the friction at the cam–follower interface is usually dominant in valvetrain friction (especially for the flat-faced followers), the friction from the rocker arm bearing, the camshaft bearings, and the follower/valve guides also plays an important role. The cam and follower mechanism are widely used in automobile industry. These examples are a little extreme but serve to demonstrate the principle. The object that moves up and down, or otherwise tracks the cam's movement, is called (surprise, surprise) the follower. Used for One Cycle: One rotation/revolution of the cam. Cam makes a higher kinematic pair with follower. The weight of the follower keeps them in contact. Qianfan Xin, in Diesel Engine System Design, 2013. Cam**:** The cam is the driver. The cam shaft is rotated and, according to the cam profile, the follower moves up and down. The cam, while rotating, pushes the follower along a linear rail. If you turn the cam, the follower will move. CAMS Yatin Kumar Singh Page 21 Fig.8.21 Cam with radial roller follower Cam Profile: The cam profile shown in Fig.8.22 (b) may be drawn as explained below: Draw the base circle with centre O and radius 50 mm. cam and follower definition, concept ,applications ,examples and classification of followers is covered. 1.2 Classification of CAM Mechanism Based on modes of Input / Output motion 1.2.1 Rotating cam – Translating follower 1.2.2 Rotating cam – Oscillating follower 1.2.3 Translating cam – Translating follower … The cam turns around the blue circle in each case. In a cam follower pair, the cam normally rotates while the follower may translate or oscillate. Being a follower teaches you how to be aware of the needs of other people as well as their potential to “make my life hell from one second to the next,” she says. The driver is called the cam and the driven member is called the follower. engines, feed mechanism in the lathe machine etc are the mechanism of cam and follower. reciprocating. rotary. Cam arrangements, involving a cam and a cam follower, are used in various applications to translate rotational movement into linear movement. Match. Cams can provide unusual and irregular motions that may be impossible with the other types of mechanisms. Follower moves up and down 1 time. However, the manufacturing of cams is expensive and the wear effect due to the 10.7.7 Friction analysis of valvetrain bearings and guides. Real Life Example Key Phrases Our cam and follower By: Sara G, Arissa L, Serenidy M, Salma R WMS PLTW Period 3 Types of cam and followers -Flat follower -Roller follower -Point/knife follower -Curved shoe follower. Gravity. Features of the Cam Follower Needle roller Cage Outer ring Seal Side plate Stud Fig.1 Structure of Cam Follower Model CF UU-A Structure and Features The Cam Follower is a compact and highly rigid bearing with a shaft. The cam, too, can vary in design. Loads, speeds, and life requirements. From pulling curtains up to lifting heavy machinery, pulleys are vital in many equipment and utilities. List of Examples of Pulleys in Our Daily Life. So far I have got Toys, Machines and Interactive Displays. Cam followers come in a vast array of different configurations, however the most defining characteristic is how the cam follower mounts to its mating part; stud style cam followers use a stud while the yoke style has a hole through the middle. The cam converts rotary motion of one element into reciprocating (linear) motion or into oscillatory motion. Follower inhibits the push and pulls of the Cam. First Mover or Fast Follower? Examples are given to show that variable cam-input design approach works nicely when we require that the velocity and acceleration are continuous and the jerk is finite. The cam and follower mechanism is widely used for operating the inlet and exhaust valves of internal combustion engines. Spell. To select a cam follower bearing for a cam or track system, consider the load magnitude and type, speed, deflection, misalignment, and lubrication. Cams can be circular, pear shaped, or irregular. Draw the reference circle with radius equal to the sum of the radius of base circle and roller radius, i.e., 60 mm. "Examples of where you may find a cam mechanism in real life"? The shape of the cam depends upon its own motion, the required motion of the follower and the shape of the contact face of the follower. The profile of a cam allows it to control the timing and degree of movement of a follower. Rotating Cam/Rotating Follower This article enlists such examples, along with pictures, that we come across in our everyday lives. The wheel creates rotational motion when the water is falling down, this wheel is directly connected to a bar, which is also connected to a cam and follower. https://www.pcma.org/servant-leadership-mastering-real-life-examples It is normally connected with a prime mover, which rotates it. 2.1 Rotating cam/Translating follower. More complicated cam mechanisms require the engineer to add other components to ensure that the follower keeps in contact with the profile.
