What is a radial plate cam with knife edge follower?
The ‘radial cam’ is a rotating plate or disc with an outer circumference shaped to produce a required movement (usually linear) to a ‘follower’ which is held against it.
What is a knife edge follower used for?
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.
What are the three types of 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 are the different types of cam followers?
Wedge or Flat Cam. The wedge or flat cam has a straight shape to provide a specific movement of the followers.
What is a radial plate cam used for?
A radial cam converts a rotational motion into a translational motion of the follower. The displacement of the follower is determined by the cam’s profile. This Demonstration generates a cam profile starting from a displacement diagram defined by a set of locators.
What are the limitations of knife edge follower?
Limitations of knife edge follower are: Excessive wear due to small area of contact between cam & follower surfaces. 2. In this follower a considerable thrust exists between the follower and guide.
Why knife edge follower is obsolete now?
Answer: In case of knife edge follower there is sliding motion between the contacting surface of cam and follower. Because of small contact area, there is excessive wear; therefore it is not frequently used.
What is a radial cam used for?
What is radial cam?
What are the 6 types of cams?
What are the different types of CAM?
- Chinese or Oriental medicine.
How many types of radial cam are there?
There are two types of Head Cams. First is Single Head Cam and the second is Multiple Head Cam. Cam is Rotating about minor axis or respect to Follower.
How does cam follower work?
A cam and follower mechanism is a profiled shape mounted on a shaft that causes a lever or follower to move. 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.
