Convert Rotary Motion To Linear–From The Inside

Aug 23, 2007· Figure 1. One way to convert rotary motion into linear is through a leadscrew and nut assembly inside the motor. This approach lets you use a “drop in motor” in your designs, eliminating the need for external mechanical linkages.

can turn circular motion into square motion by a purely mechanical linkage; an application is to the construction of a drill that drills exact square holes. We conclude with an extension of this idea to a drill that drills hexagonal holes. A wellknown construction that comes close is due to James Watts, who in 1914 had the idea of rotating a

Sarrus linkage Wikipedia

A Sarrus linkage produces linear motion from a hinged mechanism. The Sarrus linkage, invented in 1853 by Pierre Frédéric Sarrus, is a mechanical linkage to convert a limited circular motion to a linear motion or vice versa without reference guideways. It is a spatial sixbar linkage (6R) with two groups of three parallel adjacent jointaxes.

Converting Rotational Motion to an Oscillating Motion

When designing a machine or mechanism and the task requires converting rotational motion to an oscillating motion, these designs should be the first to come to mind. Every application is specific and each design must be custom tailored to suite it’s needs, but the underlying basic design and function of these 4 bar linkages is the same.

Linkage (mechanical)

Watt's linkage (also known as the parallel linkage) is a type of mechanical linkage invented by James Watt (19 January 1736 – 25 August 1819) in which the central moving point of the linkage is constrained to travel on an approximation to a straight line.

Aug 15, 2013· I want to make a prop similar to a tombstone popper, where a head will move up and down. The linkage for the tombstone popper creates a small circular motion as it moves up and down. I’d prefer the movement to be straight up and down. I want to do it mechanically with a wiper motor and not get into any pneumatic type of animation.

FourBar Linkages University Of Illinois

As most motors (electrical or internal combustion) provide a rotating drive shaft, some way is needed to convert the rotary engine motion into reciprocating pump motion. A pumpjack is a drive mechanism to achieve this, consisting of a fourbar linkage as shown below. The heavy rotating counterweight is arranged so that it is falling while the ...

In 1784, Watts devised a linkage to which he gave the name ‘Parallel (straight line) motion’ which was included in an extensive patent. Years later he told his son: “Though I am not over anxious after fame, yet I am more proud of the parallel motion than of any other mechanical invention I have ever made.”

If this is true linear motion (nonrotational) then you will need some sort of a pivoting linkage in between the two units to transfer one motion to the other. Something like this would probably work: As the lower link moves vertically, it rotates the red gear which in turn pushes the second link horizontally.
