What does a cam follower do?
Crowned cam followers are used to keep the load evenly distributed if it deflects or if there is any misalignment between the follower and the followed surface. They are also used in turntable type applications to reduce skidding.
What is a stud cam follower?
SKF cam followers (stud-type track rollers) are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. They are based on either needle (fig. 1) or cylindrical (fig. 2) roller bearings. Instead of an inner ring, they have a threaded solid stud (pin).
How do eccentric cam followers work?
An eccentric cam is a disc with its centre of rotation positioned ‘off centre’. This means as the cam rotates the flat follower rises and falls at a constant rate. This type of cam is the easiest to make and yet it is one of the most useful.
What is a Camrol?
CAMROL is the trademark for the line of roller bearing cam followers manufactured by McGill and designed for use as cam followers and track rollers. The CAMROL Cam Follower Bearing was origi- nally invented by McGill over 60 years ago.
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 are the different types of cam followers?
The Cam and Follower Mechanism is mostly used in the IC engines for driving the valves….There were various types of follower which are bellowed:
- Knife edge follower.
- Roller follower.
- Flat-faced follower.
- Spherical follower.
- Radial follower.
- Offset Follower.
How is cam and follower used in real life?
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.
How do you classify the followers of cam?
Movement of follower is depending upon cam profile for this; cams are also classified according to follower movement. In this type, follower movement is considering….CLASSIFICATION OF CAMS
- Radial or Disc cam.
- Cylindrical cam.
- Translation or wedge cam.
- Conjugate cam.
- Globoidal cam.
- Spherical cam.
Where is the cam and follower used widely?
What are the four types of cams?
Cams and followers
- 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.
How do you classify the followers of cams?
What are the elements of cam and follower?
A cam mechanism consists of three elements: a) the cam, b) the follower (or follower system), c) and the frame. The follower is in direct contact with the cam. The cam may be of various shapes.
What are the advantages of cam and follower?
Cam and Follower Advantages: Cam and follower bearing are that they always distribute evenly, regardless of the configuration of the unit. A wide range of linear motions is available from cams and followers. Cam follower can absorb more shock than normal and can reduce distortion. They are highly versatile.
What are 3 disadvantages of cam?
Disadvantages of CAM
- Computer errors are possible.
- CAD and CAM software can be expensive.
- Training is expensive.
- Computers and controllers to run the software and CNC machinery for manufacturing is expensive.
What is an example of a cam and follower?
A common example is the traditional sash window lock, where the cam is mounted to the top of the lower sash, and the follower is the hook on the upper sash.
