About This Product
A crank and connecting rod is the basic linkage that turns rotary motion into reciprocating motion, as in engines and compressors. On this unit the crank disc is turned to a chosen angle, and the matching output stroke is read off the millimetre scale. Students change the crank radius and the connecting rod length and see how each changes the stroke. With the cylinder fixed or allowed to swivel, they can compare a fixed cylinder drive with an oscillating cylinder drive. School Lab Equipment India supplies the Crank And Connecting Rod Apparatus across India and can export it to Central African Republic, Poland, North Macedonia, Guinea-Bissau and South Korea.
Frequently Asked Questions
Q1. What does the Crank and Connecting Rod Apparatus demonstrate?
It demonstrates the conversion of smooth rotary motion into reciprocating motion.
Q2. What can be adjusted on the unit?
The crank radius and the connecting rod length can both be adjusted, each with three positions. The swivelling cylinder can be locked with a bolt, so a crank drive with a fixed or oscillating cylinder can be shown.
Q3. How are the angle and stroke read?
The input angle is read on an angle measuring scale built into the base plate, and the outlet stroke on a millimetre scale.
