What is the cam monitor?
The cam monitor is a bearing type usually used to replicate specific movement. In the cam and follower system, the cam is a mechanical element often in the form of a flat piece of metal tool to an elongated shape that rotates or slips. The follower travels along the surface of the cam and monitors the shape of its edge and converts this shape into a movement pattern. The CAM follower works on a very simple principle and can be applied to a large number of tasks, because although it is basic, it is also highly versatile. Tracking cams are used in a wide range of equipment, including motor vehicles, movable lawn and pumping decorations.
These systems usually take the form of a rotating rod that turns the cam or cams, and the followers mounted close. Where the CAM follower is mounted precisely and which type of viewer is used, it depends on the purpose of the system and many different configurations are available. These follower must be maintained in smooth and even contact with the cam, gravity, PRužina, groove or other stabilization method, or will not be able to translate movement effectively. Without the stabilization force on the follower system, the follower may tend to fluctuate or vibration, which potentially causes a failure in the device that is moved by the cam and the follower.
Subscriber and cams' suggestions
cam followers also have different head patterns. The follower with a pointed head will hold more precisely and replicate the movement of the cam, but it is also more likely to wear faster and require replacement. Followers with wider heads will not wear so easily, but some accuracy will usually be sacrificed. In other applications, the head may have a cylinder rather than being flat or pointed to allow smoother movement.
There are a number of different types of cam followers, each of which can support different amounts of strength and speed appliedČkou. One of the most common types is a needle that contains long, sometimes pointed bearings; These counter -created elements inside the camsmith allow them to move smoothly and promote heavier loads. Another type, cylinder in the cage, is similar, but the needles are separated by the cage; This allows for more lubrication and operation of higher speeds, but cannot support such a high load.
One of the main differences between followers is how they are connected to the device. Student -style watching includes built -in standard or cumbersome thread rods and can usually be mounted quickly and easily. The built -in pin can be comfortable, but its strength is limited by how much load that shame can support. The yolk -style follower has a hole in the middle; It is less convenient to connect, but a higher strength pin can be used.
Most cams are made in simple shapes designed to create basic movements - the more complex the shape of the cam, the harder the follower must work to translate it. Many withThe cams of the cams of the cams have the shape of the tears or has a single jagged insert to create a specific movement. Systems of followers used on motor vehicles to control pistons, for example, have a tears shape that causes sharp up or displacement as The follower reaches the peak of the tears and causes the attached piston to fire.
uses
Although CAM systems and followers are used in a wide range of mechanical applications, they can be the most famous for their role in cars and other motor vehicles. In motor vehicles there are multiple cam monitors systems, one for each cylinder and are compensated so that all pistons do not shoot at once. All systems can be mounted on one camshaft, so they most use the energy used to rotate the shaft than the dedicating energy for each piston individually. In this case, the damage to one monitoring of the cam could cause the engine to be omitted.
