Cam follower mechanism application
Cam followers are mechanical components that convert rotary motion into linear motion, or vice versa. They are often used in mechanical systems to transfer motion from one component to another, or to transmit a load from one component to another.
One common application of cam followers is in the field of robotics. Many robots use cam followers to actuate their joints and limbs, allowing them to move and manipulate objects. For example, a robot arm may use cam followers to control the movement of its joints, allowing it to reach and grasp objects.
Cam followers are also commonly used in the automotive industry. In internal combustion engines, cam followers are used to actuate the valves, which control the flow of air and fuel into the engine. In transmission systems, cam followers may be used to transfer rotary motion from the engine to the drivetrain, allowing the vehicle to move.
In the field of manufacturing, cam followers are used in a variety of applications, such as material handling, packaging, and assembly. They are often used to control the movement of conveyor belts, which transport materials from one location to another. In packaging systems, cam followers may be used to control the movement of packaging machinery, such as filling and sealing machines. In assembly lines, cam followers may be used to control the movement of parts, allowing them to be accurately placed and fastened together.
Overall, cam followers are versatile mechanical components that are used in a wide range of applications. They are an important component of many mechanical systems, and their ability to convert rotary motion into linear motion, or vice versa, makes them essential for many industrial and technological applications.
Cam and Follower Mechanism and types of Cams opportunities.alumdev.columbia.edu
It is also called as the throw of the cam. This can be clearly seen by comparing Figures 2 and 6. What are different types of cam? Read also : Classification of Followers Followers may be classified in three different ways : a Depending upon the type of motion, i. The motion of the cam is represented by a graph drawn between follower displacement and angle. .
In order to obtain the most satisfactory acceleration curve, an acceleration curve can be given in numerical form, and then the displacement curve is obtained by the finite difference method, and finally the convex contour is designed. What is cam and its application? Compression springs are preloaded into the follower to ensure contact with the surface at all times. This part of the machine follows the cam motion. Cams can convert the rotational motion from you turning the key into linear motion which moves the bolt. Types of Cams The cam may be of various shapes.
Cam And Follower Mechanisms
On the shaft 1 is rotatably mounted a cam disc 4 formed on one side with an annular cam r-ib 5, the inner and outer faces 6, 7 of which constitute complementary cam surfaces. If possible, use a fine mesh on a cam boundary to improve the accuracy of the mesh normal used in the Cam-Follower connection node. Below Fig-d shows the displacement diagram for the rise-return-dwell type of cam. Central locks and ordinary lock systems are also developed by incorporating the mechanism of cam and follower. As a result, the radius of the base circle we designate Rb is referred to as the base circle radius. The cam is the name given to this profiled body. Unlike a regular fuel pump, the HPFP is able to provide this bigger engine with enough fuel to run sufficiently.
What is the Cam Follower mechanism?
An oscillating follower around a fixed point is achieved using a globoidal cam. The tip follower can keep in contact with any complex cam profile for any movement. Large size is challenging to operate. The follower rise function is defined as the displacement of the follower with change in the cam rotation. The push helps to take the position where the printing will be done and the pull helps to print on that.

In mushroom followers there is no side thrust on the guide except that due to friction at the contact of the cam and the follower. Drawing cam profile The figure shows the cam profile for the constant velocity profile mentioned above. Prime circle Aprime circle is the smallest circle that can be formed with the cam center as the center and with the pitch curve as the tangent to it. Cam is a higher pair device thus, the user should grant the degree of freedom to apply the same in a machine component. In order to transform rotational motion into linear reciprocating motion, cams are employed. If the cam follower wears all the way, damage to the cam shaft and fuel pump will probably follow.
Cam and Follower Mechanism
The whole process takes place within one cam revolution. Like any component, the cam follower will eventually wear. The spring rate as the valve moves from the position corresponding to point I in Figure 6 to the fully open position 0 is therefore less than it was for movement from C to I. If we rotate the cam, the follower will only reciprocate; it will not reciprocate and oscillate together. In COMSOL Multiphysics, one can easily create a geometry based on the follower rise function. Schematic of the generated cam profile.
Cam and Follower: Types, Working Principle, Applications & Advantages
In this cam, the follower moves in such a way that first rises and then returns. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed. The different types of cam-follower mechanisms are described below. What is a follower? In practice this reduction in pressure significantly reduces the power required to drive the cam mechanism against friction effects. This type of cam is called a box cam.
Cam and follower mechanism types and functions
Based on what I saw, I'm going to replace every 30-40,000 miles. Translating Cam Thekind of cam in which the cam may move in a horizontal plane is made up of a curved plate with grooves or contours that slides on a guiding surfaceis known as a translating cam. At first, the user should aware of the links and pairs before understanding the conception of cam and follower. The spring acts against a flange 51 and the operation is similar to that of the spring described above with reference to Figures 3 to 6. Spherical follower, flat follower, roller follower, and knife edge follower are the most common examples of reciprocating followers. The Pressure Angle The angle included between the normal to the pitch curve at any point and the line of motion of the follower at the point is known as the pressure angle. Cam pairs are classified as force closed or form closed.
