In very crude terms, rotary motion is round & round, reciprocating motion is back & forth.
A piston engine has both kinds of motion. The crankshaft displays rotary motion, the pistons display reciprocating motion. The camshaft displays rotary motion, the valves display reciprocating motion. Out on the suspension, the wheels display rotary motion and the shock absorbers display reciprocating motion. (One might say the shocks don't display "true" reciprocating motion because they're not CONSTANTLY in motion, but that one drives on better roads than they have here!)
The Cam
The crankshaft and connecting rod (or piston rod).
Tropicalized Rotary means
A reciprocating engine is different than when using rotors. Rotors are used in a pistonless rotary engine, using one or more rotors and sometimes called rotary pistons.
Double slider crank mechanism is used where two slider works or the crank also work as a slider it uses to transform Reciprocating motion into rotary
It is the reciprocating motion of the pistons that is changed into rotary motion by the cam axle.
The Cam
A rotary compressor has screws or gears that compress a gas. A reciprocating compressor has a piston in a cylinder compressing the gas.
Crank and slider
spiniards
The crankshaft and connecting rod (or piston rod).
Rotary means going around, like in a Wankel. Reciprocating means going back and forth. like in a ordinary piston engine.
connecting rod is provided between crank and the piston,which converts the reciprocating motion of the piston into rotary motion of the crank.
The four types of motion mechanisms are rotary motion, linear motion, oscillating motion, and reciprocating motion. Rotary motion involves circular movement, linear motion involves movement in a straight line, oscillating motion involves back and forth movement, and reciprocating motion involves alternating movement in opposite directions.
Crankshaft transfers a reciprocating motion into a rotary motion into transmission which makes vehicle move.
Scotch Yoke Mechanism is a mechanism in which the rotary motion is converted to reciprocating motion, with a single link or bar. The reciprocating system has to be constrained along the guide ways for linear motion.
Two types of system I can think of:A cam mounted on a rotating shaft can push against a rod. If the rod is held against the cam by a spring then the system is capable of reciprocating action.A crank: The crank attached to the pedals on a bicycle is an example, although it converts reciprocating motion to rotary motion.
