What type of motion is involved going from a cam to a follower?

Cams are used to convert rotary to linear (reciprocating) motion. As the cam rotates, the follower rises and falls in a process known as reciprocating motion.

What offset is provided for a cam follower mechanism?

When the motion of the follower is along an axis away from the axis of the cam centre, it is called off-set follower. Offsets are required in cam and followers to reduce wear and side thrust.

What is lift in cam and follower?

Lift of stroke: It is the maximum travel of the follower from its lowest position to the topmost position. The maximum rise is called lift. Pitch Point: It is a point on the curve having maximum pressure angle. Pitch Circle: It is the circle drawn from the center of the cam through the pitch points.

What object uses a cam and follower?

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. They are also used in paper cutting machines and weaving textile machinery.

What is the function of cam follower?

Cam follower bearings are also known as track followers. As the name implies, they are essential to make the cam followers work effectively. Cam followers are capable of handling intermittent shock and heavy loads. They also can have a soft core that allows for extreme shock loads without fracture.

Why is offset provided in radial cam translating follower?

An offset provided in the radial cam-translating-follower mechanism is to decrease the pressure angle during the ascent of the follower because the high value of pressure angle is not desirable as it increases side thrust and performance will not be smooth.

Which motion of follower is best?

Best motion of follower for high speed cams – Theory of Machines…

a. SHM follower motion.
b. Uniform acceleration and retardation of follower motion.
c. Cycloidal motion follower.
d. All of the above.

What is an example of a cam follower?

A cam follower is a component that is intrinsically tied to a cam. Cams exist in many applications–dishwashers, sprinklers, etc. –but the most well-known example is that of a camshaft in a car. The goal of a cam is to convert rotary motion to linear motion.

What is the difference between a cam and a 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.

What is cam short for?

Cam is both a given name and a surname, often a shorthand for Cameron or Camilla (given name). Notable people with the name include: Given name: Cam (singer), born Camaron Ochs, American singer.

How is the capacity of a cam follower determined?

They publish the capacity of a cam-follower as a force/load rather than as a stress. The load, as a force, is much easier to calculate. However, the capacity assumes it operates in a perfect environment. Its capacity is actually strongly influenced by ambient lubrication, contamination, and temperature, as well as the required reliability.

How to calculate torque required by cam shaft?

Another way to approach it is to calculate the work in moving the follower, first using torque, and then using force. The two must be equal. So at any point in the motion, T dtheta = F dx. Then T = F dx/dtheta. The term dx/dtheta is the “velocity” of the follower, relative to the cam rotation angle, and is easy to get.

Which is easier to calculate force or load?

Luckily, suppliers of cam-follower bearings have done the hard work for engineers. They publish the capacity of a cam-follower as a force/load rather than as a stress. The load, as a force, is much easier to calculate.

When does a bearing have a contact force?

When a bearing is continuously loaded with a contact-force, P, equal to the Dynamic Load Rating, C, the bearing has a life, L10 , of one life. One life is one-million (1 × 106 ) rotations.
