Across
- 1. A small cogwheel (pinion gear) that engages or is engaged by a larger cogwheel (crown gear).
- 6. The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
- 7. The member of a pair of gears to which motion and power are transmitted by the other. The output gear.
- 13. A rotating gear that meshes with a bar that has gear teeth along its length. Changes rotating motion into linear motion.
- 15. The results of the operation of any system.
- 16. A pear-shaped disk with an off-center pivot point, used to change rotating motion into reciprocating motion.
- 17. A toothed wheel that works with others to alter the relation between the speed of an engine and the speed of the driven parts.
- 19. A push or pull on an object.
- 22. A joint that allows connected shafts to spin freely while permitting a change in direction.
- 23. Something put into a system, such as resources, in order to achieve a result.
- 24. The transmission of power between shafts by means of a belt connecting pulleys on the shafts.
- 26. One of a pair of gears used to connect two shafts whose axes intersect.
- 27. The part of a machine which contains two or more pieces arranged so that the motion of one compels the motion of the others.
- 28. A pivot pin near the outside edge of a wheel or disk that changes reciprocating motion into rotary motion.
- 29. A back and forth movement.
Down
- 2. A gear between the driver and the driven gear used to change rotational direction.
- 3. Circular movement.
- 4. A mechanical arrangement consisting of a toothed wheel driven by a short revolving cylinder bearing a screw thread.
- 5. The ability to do work.
- 8. The distance between adjacent threads in a screw.
- 9. A twisting force.
- 10. A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide.
- 11. Movement in a straight line.
- 12. A swing back and forth at a regular rate.
- 14. The ratio of the speed of the driving member of a gear train to that of the driven member.
- 18. The application of force that moves an object a certain distance.
- 20. Opposite in position, direction, order or effect.
- 21. The gear which transmits power and motion to the rest of the system. The input gear.
- 25. A threaded shaft used to convert rotary movement to linear movement.
