Different types of cams mechanical engineering

Actually, owing to the inertia of the follower, it is only during the first part of the out-stroke and the latter part of the return that the motion of the follower is positively controlled by the cam. Cam profile is outer surface of the disc cam.

Hydrology engineering is the focus of quantity and quality of water on the land surface. A mechanical engineer can design, build, test and produce any machine or device.

This could include the wiring or the lighting of buildings.

Cam and Follower Mechanism And their Types

Cams are mechanical devices that convert rotational motion into linear motion. Acoustical Engineering This is rather an excellent degree to choose for those who want wider prospects for scientific and engineering career options. In this connection it should be noticed that the cam does not, as would at first appear likely, determine the motion of the follower during the whole of the its out-stroke.

The engineer oversees all aspects of the project from start to finish. Jobs for mechanical engineers can be found in all areas of society. These engineers evaluate the quality of the soil and other elements to determine whether the particular project is suitable for the chosen site or not.

Bevel gears translate rotation 90 degrees and are used as an integral part of vehicle drive trains. In a cam follower pair, the cam normally rotates while the follower may translate or oscillate.

A follower with a wheel-type contact, though, must remain aligned. The cam profile may be cut into one or more edges of a plate or block, may be one or more slots or grooves in the face of an element, or may even be a surface profile for a cam with more than one input.

Creative Mechanisms Staff on February 18, Engineering mechanisms are simple devices that make a huge difference in our day-to-day lives often without us even realizing it.

Prime circle is the smallest circle that can be drawn so as to be tangential to the pitch curve, with its centre at the cam centre. History[ edit ] An early cam was built into Hellenistic water-driven automata from the 3rd century BC.

This type of follower also produces a considerable side thrust. Generally, this type of engineer takes care of the implementation and design of computer programs or specialist industry equipment in most cases.

Two particular motions of the follower are frequently specified.Circular cams cause smooth linear motion, heart cams maintain a uniform velocity in the cam follower, and drop cams produce a rapid and discontinuous linear motion.

Different Types of Cams (Mechanical Engineering) Radial cam with a knife edge follower In the radial cams, the working surface of the cam is designed such that follower moves in a plane perpendicular to the axis of the cam performing a reciprocating motion.

Cams convert ordinary shaft rotation into a more complicated pattern of motion. This is accomplished by keeping one or more followers in contact with the surface of a rotating cam.

Aerospace engineering is a branch of mechanical engineering which deals with the designing and construction of aircraft. It is an exciting profession as it is focused on the development and use of various technologies relevant to a rapidly changing, high-tech industry.

Cams can be classified into the following three types based on their shapes. They are: Plate or disk cams: Plate or disk cams are the simplest and most common type of cam.

A plate cam is illustrated in figure 3 (a). This type of cam is formed on a disk or plate. A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion.

It is often a part of a rotating wheel or shaft that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an eccentric disc or other shape that produces a smooth reciprocating.
