Where is a knife edge follower used?
The Knife Edge Follower: This is the simplest type, is not often used due to the rapid rate of wear. When it is adopted, it is usually for reciprocating motion, running in slides and there is considerable side thrust, this being a component of the thrust from the cam.
Where can cams and followers be used?
Application of Cam and Follower
- Cam and follower are widely used for operating inlet and exhaust valve of I C engine.
- These are used in wall clocks.
- These are used in the feed mechanism of the automatic lathe Machine.
- Screw pieces of machinery.
- Gear-Cutting Machineries.
What are knife edge followers?
1) Knife edge follower: In this type of follower, the contact end of the follower is Knife edge which is used to contact with the surface of the cam. Due to the high wear rate, the use of Knife edge follower is used less. In this sliding motion is occurring.
Where are flat followers used?
Flat Followers These are used where space is limited e.g. to operate valves in a car engine. The contact surface is perfectly flat.
Where are cam mechanisms used?
Cam mechanisms are used in various areas of machine building, such as internal-combustion engines, metal-cutting machines, and machines of the food industry, in which the cam mechanism performs a programmed operation, as well as in automated machines, in which cam mechanisms perform control functions, connecting and …
Which type of cam follower is used in automobiles?
knife edge follower
knife edge follower.
What is a cam used for?
Cams are mechanical devices used to convert the rotation of a shaft into simple or complex reciprocating linear motion. They can be sliding or rotational pieces in a mechanical linkage.
What other things use a cam mechanism?
Cams are commonly used in engines to control valves (in which the valve is the follower), sewing machines, children’s toys and many other mechanical applications. The shapes of individual Cams are designed to produce specific types of motion.
Where are cams used in society?
Cams are essential elements in automatic machine tools, textile machinery, sewing machines, printing machines, and many others. If the follower is not restrained by a groove on the cam, a spring is necessary to keep the follower in contact with the cam.
What’s the difference between a knife edge follower and an offset follower?
The above-mentioned Knife edge follower, roller Follower and flat-faced followers are the radial follower. Whereas the offset follower is having an offset distance between the axis (Motion Axis) of follower and the centre of the Cam which is already mentioned in the flat-faced follower to reduce the side thrust.
What are the types of Cam and follower?
When the motion of the follower is along an axis which is passing through the centre of the Cam, then these types of followers comes under the Radial Followers. The above-mentioned Knife edge follower, roller Follower and flat-faced followers are the radial follower.
Is the follower surface in contact with the cam flat?
The follower surface which is in contact with the cam is in the form of a flat surface is called flat face follower. The follower surface, instead of flat, can be also a curved surface.
How does a rotating follower in a cam work?
Rotating follower (Figure 6-2f): The follower arm swings or oscillates in a circular arc with respect to the follower pivot. Translating cam-translating follower (Figure 6-3). Stationary cam-rotating follower:
