As nouns the difference between cam and follower
is that cam is a turning or sliding piece which imparts motion to a rod, lever or block brought into sliding or rolling contact with it or cam can be (informal) camera while follower is (literally) one who follows, comes after another.
Also What is follower and Iscam?
The mechanism is developed by incorporating three members they are, a driver member named Cam, a frame that supports cam and follower, the follower is guided by the frame and lastly, the driven member named as a follower.
Subsequently, What does a cam do? Cam is shorthand for camshaft, the engine part that opens and closes the valves to let the air-fuel mixture in and out of the combustion chambers. Every roadgoing production car engine has at least one, and many current engines have two or more.
What does a cam and follower do in a wall clock? The cam and follower mechanism is widely used for operating the inlet and exhaust valves of internal combustion engines. They are used in wall clocks and the feed mechanism of automatic lathe machines. … The contact end of the follower is roller and the rolling motion exists between the cam and follower.
What is the function of cam?
A cam, in its simplest definition, is a mechanical link that converts rotational motion into linear motion, or vice versa. The cams on a camshaft achieve this displacement by the rotation of a radial pattern, and a follower which moves perpendicular to the rotational axis.
What is knife edge follower?
[′nīf ‚ej ′kam ‚fäl·ə·wər] (design engineering) A cam follower having a sharp narrow edge or point like that of a knife; useful in developing cam profile relationships.
What are followers in an engine?
The cam lifters and followers are a part of your vehicle’s internal combustion engine. The cam follower is a cylindrical device that tracks the shape of the cam lobe and reciprocates the movement to the opening and closing of the valves in the combustion chamber.
Does a cam give you more HP?
Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. You’ll idle slightly rougher with a performance cam, but get a throaty rumble that’s desirable for some gearheads, depending on your vehicle.
What does a cam do for performance?
Adjusting the camshafts so the cams are slightly ahead or behind will alter the engine’s performance. Advancing the timing will cause the fuel intakes to open and close earlier, which improves low-end torque. Conversely, retarding the cam will improve high-end horsepower at the expense of low-end torque.
Are cammed cars illegal?
yes, unless it comes with a CARB certification number. Any modification is illegal (even just changing the mufflers) unless it’s certified by CARB.
What is the function of cam and how it classified?
A cam is a rotating machine element which gives reciprocating or oscillating motion to another element known as follower. The cam and the follower have a line contact and constitute a higher pair.
How does a face cam with roller follower work?
A face cam produces motion by using a follower riding on the face of a disk. The most common type has the follower ride in a slot so that the captive follower produces radial motion with positive positioning without the need for a spring or other mechanism to keep the follower in contact with the control surface.
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 …
What is function of cam and how it classified?
A cam is a rotating machine element which gives reciprocating or oscillating motion to another element known as follower. The cam and the follower have a line contact and constitute a higher pair.
How does a cam work?
How do cams work? Cams generally do the opposite job to cranks: they turn rotary motion into reciprocating motion. Whatever you need to move up and down (or back and forth) rests on top of an oval wheel, sometimes mounted off-center (the cam). As the cam rotates, the object it supports rises up and down.
Why knife edge follower is obsolete now?
In case of knife edge follower there is sliding motion between the contacting surface of cam and follower. … Whereas in roller follower there is rolling motion between contacting surfacing and more contact area, therefore rate of wear is greatly reduced.
What are the three types of cam?
Cams
- Circular. Circular cams use an off-centre pivot to cause the follower to move up and down. …
- Pear. Pear cams are called this as they have the shape of a pear. …
- Snail or drop. Snail or drop cams have the appearance of a snail shell. …
- Heart-shaped or constant velocity.
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 are valve followers?
[′valv ‚fäl·ə·wər] (mechanical engineering) A linkage between the cam and the push rod of a valve train.
Are valve lifters and cam followers the same?
In an internal combustion engine, a tappet (also called a ‘valve lifter’ or ‘cam follower’) is the component which converts the rotation of the camshaft into vertical motion which opens and closes the intake or exhaust valve.
What are the types of followers?
In 1988 Robert E. Kelley developed a theory of followers describing five types: Conformist, Passive, Alienated, Exemplary and Pragmatic. Ira Chaleff’s Styles of Followership (2003) proposes four distinct follower types: Resource, Individualist, Implementer and Partner.
How much HP does a Stage 2 cam add?
Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination. A typical Stage 2 has generally +20-25% more HP than stock. Stage 4: this would be a moderate compression big bore combination.
What does a bigger cam do for an engine?
Generally speaking, the longer the duration the higher the operating range of the cam. Short duration cams are good for low speed torque and throttle response, while long duration cams hold the valves open longer for better high speed breathing.
How much HP does a tune add?
To give a ballpark figure – if you are on a stock car, you could probably gain 10-15 horsepower from a dyno tune. However, if you are running on performance parts like exhaust and turbo, then 50 horsepower gain is possible – even more depending on your engine and what performance parts you equip.
