2. Rotary saw - Wikipedia

   en.wikipedia.org/wiki/Rotary_saw

   A rotary reciprocating saw is a type of saw that spins a cutting implement around a rotary axis, instead of thrusting it along a linear axis. The first use of such devices was in medicine , where cutting through bone warranted the need for a saw with minimal stroke length, and a cutting action that could be implemented through depth cut rather ...

3. Stroke ratio - Wikipedia

   en.wikipedia.org/wiki/Stroke_ratio

   An engine is described as oversquare or short-stroke if its cylinders have a greater bore diameter than its stroke length, giving a bore/stroke ratio greater than 1:1. An oversquare engine allows for more and larger valves in the head of the cylinder, higher possible rpm by lowering maximum piston speed, and lower crank stress due to the lower ...

4. Piston motion equations - Wikipedia

   en.wikipedia.org/wiki/Piston_motion_equations

   For rod length 6" and crank radius 2" (as shown in the example graph below), numerically solving the acceleration zero-crossings finds the velocity maxima/minima to be at crank angles of ±73.17615°. Then, using the triangle law of sines, it is found that the rod-vertical angle is 18.60647° and the crank-rod angle is 88.21738°. Clearly, in ...

5. Reciprocating motion - Wikipedia

   en.wikipedia.org/wiki/Reciprocating_motion

   Reciprocating saw – Type of machine powered saw; Reciprocating engine – Engine utilising one or more reciprocating pistons; Rotary reciprocating saw – Type of mechanical saw; Agitation – Device or mechanism which shakes or stirs something; Scotch yoke – Mechanism to convert between rotational and reciprocating motion

6. Engine displacement - Wikipedia

   en.wikipedia.org/wiki/Engine_displacement

   The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. [2] The formula is:

7. Reciprocating saw - Wikipedia

   en.wikipedia.org/wiki/Reciprocating_saw

   A reciprocating saw is a type of handheld, small, machine-powered saw, in which the cutting action is achieved through a push-and-pull ("reciprocating") or back-and-forth motion of the blade. The original trade name, Sawzall , is often used in the United States , where Milwaukee Electric Tool first produced a tool of this type in 1951.

8. Scotch yoke - Wikipedia

   en.wikipedia.org/wiki/Scotch_yoke

   The Scotch yoke (also known as slotted link mechanism [1]) is a reciprocating motion mechanism, converting the linear motion of a slider into rotational motion, or vice versa. The piston or other reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part.

9. Mean piston speed - Wikipedia

   en.wikipedia.org/wiki/Mean_piston_speed

   The comparison of mean piston speed (black line) with real piston speed (color lines). Diagram shows one stroke from BDC to TDC. Revolution = 1.000 min-1, stroke = 88 mm. The connecting rod ratio l/r varies: 3 - red, 4 - green, 5,5 - blue. The mean piston speed is the average speed of the piston in a reciprocating engine. It is a function of ...
