Hi ... I was trying to figure out a mechanism which allows for up and down movement. I figured a piston with crankshaft... anyone has any other possibilities?
Thanks
Thanks
In summary, the conversation discusses different possibilities for creating up and down movement, such as using a piston with a crankshaft or an elevator. The speakers also talk about the importance of considering factors like size, force, and speed when choosing a mechanism. One person suggests using two pistons with a cam and electric motor, while another points out that this design already allows for linear motion. The conversation also touches on the concept of a double slider 4 bar chain and the use of a bearing for vertical motion.

How about an elevator? How about a car jack, or a fork-lift? You need to be more specific in order to answer your question.
Mainly: size, force, speed.

@firevia, how do you plan to move pistons??
@rvr, there are lot of ways to get linear motion, deciding factor remains the application. You ll have to come up with an application to decide which one to choose.

well it is simple , we should install a rod with a cam for the horizental piston and install an electric motor to the (cam-cranck shaft) , velocity can be easily calculated depending on the rpm of the electrical motr , but to make a full design I need configurations.

But why do you need the second piston?? You already have a linear reciprocating motion with cam!
And by the way, the linkage you showed is a double slider 4 bar chain, its an elliptical trammel

a bearing allows for vertical motion
1. What is a mechanism with up and down movement?
A mechanism with up and down movement is a mechanical system or device that can move objects or components in both an upward and downward direction. This type of mechanism is commonly used in various machines, such as elevators, cranes, and hydraulic systems.
2. How does a mechanism with up and down movement work?
The specific workings of a mechanism with up and down movement can vary depending on its purpose and design. However, most mechanisms with this type of movement involve the use of a power source, such as a motor or hydraulic system, to move a component or object along a vertical axis. This can be achieved through the use of gears, pulleys, or other mechanical components.
3. What are the advantages of using a mechanism with up and down movement?
There are several advantages to using a mechanism with up and down movement. One of the main benefits is its versatility, as it can be used in a wide range of applications and industries. Additionally, this type of mechanism can often be more efficient and cost-effective than other types of movement mechanisms.
4. What are some examples of mechanisms with up and down movement?
As mentioned previously, there are many different types of mechanisms that utilize up and down movement. Some common examples include elevators, scissor lifts, hydraulic jacks, and conveyor systems. These mechanisms are used in various industries, including construction, manufacturing, and transportation.
5. How is a mechanism with up and down movement maintained?
Maintenance of a mechanism with up and down movement will depend on its specific design and purpose. However, generally speaking, regular inspections and lubrication of moving parts can help to keep the mechanism running smoothly. It is also important to follow any maintenance guidelines provided by the manufacturer to ensure the longevity and proper functioning of the mechanism.
