Across
- 3. mechanism with minimal components which can be used to transmit or redirect mechanical power through a system
- 5. of Energy natural law stating the total energy in an isolated system remains constant over time unless external forces act on the system
- 7. type of wheel and axle with a disc-shaped wheel with teeth protruding outwards radially around the circumference of the disc; one of the most common types of gears in a robotic system
- 10. used to achieve a high gear ratio or when the engineer needs the input and output axle of a gear train to remain co-axial, also known as epicyclic gearing
- 12. cylindrical core with a continuous helical feature wrapping around it
- 13. round disc—the wheel—mounted with a cylindrical component of smaller diameter—the axle
- 14. rigid body, or beam, which pivots around a fixed point, or fulcrum
- 15. rotationally symmetric and conical, with the teeth meshing along a 45-degree angle between the two perpendicular axles
- 16. amplification of input force achieved by using a tool, machine or mechanical device; calculated by dividing the output force by the input force
Down
- 1. type of gear where two spur gears with a different number of teeth have been fused together to rotate coaxially
- 2. flat, sloped surface with one end higher than the other, otherwise known as a ramp
- 4. series of gears designed to achieve a specific output, usually one which could not easily be achieved with a single pair of gears
- 6. straight bar with teeth designed to mesh with a spur gear
- 8. arrangement of rigid bodies, or links, which pivot or slide relative to each other to transmit and redirect power
- 9. number of helical threads per linear distance of a screw
- 10. wheel on an axle or shaft which has a groove to allow a cable or belt to pass over the pulley
- 11. single, triangular rigid body which is thick on one end and tapers to a point
- 13. type of screw; helical gear meshes with a spur gear and transfers rotational power between a pair of perpendicular axles
