  1. Mechanical Division Gears, Springs, Screws, and other miscellaneous whatnot

  2. Topics Springs Screws MVRT115 Gears Other

  3. Springs

  4. Basic Types MACHINE SCREWS • ALSO KNOWN AS MACHINE BOLTS • YOUR TYPICAL BOLT/SCREW • COMES IN ALMOST EVERY HEAD TYPE MVRT115

  5. Basic Types SELF DRILLING SCREWS • DRILLS A HOLE, TAPS THREADS, AND FASTENS MATERIALS • GENERALLY NOT VERY USEFUL FOR US MVRT115

  6. Basic Types SHOULDER SCREWS • ALSO KNOWN AS SHOULDER BOLTS • HAS AN UNTHREADED SECTION UNDER THE HEAD • UNTHREADED SECTION SERVES AS A BUMPER/SPACER • SOMETIMES USED AS PSEUDO-AXLES FOR DRIVETRAIN WHEELS MVRT115

  7. Basic Types THREADED ROD • ESSENTIALLY JUST A LONG THREADED ROD. AMAZING. • USEFUL FOR A VARIETY OF PURPOSES MVRT115

  8. SPRINGS

  9. Basic Types COMPRESSION SPRINGS • GENERALLY ROUND AND CYLINDRICAL IN SHAPE • RESISTS COMPRESSION • CAN BE WOUND IN CLOCKWISE AND COUNTERCLOCKWISE DIRECTIONS MVRT115

  10. Basic Types EXTENSION SPRINGS • GENERALLY ROUND AND CYLINDRICAL IN SHAPE WITH HOOKS OR LOOPS AT THE ENDS • RESISTS STRETCHING • CAN BE WOUND IN CLOCKWISE AND COUNTERCLOCKWISE DIRECTIONS MVRT115

  11. Basic Types DISC SPRINGS • ALSO KNOWN AS WASHER SPRINGS • GENERALLY ROUND AND FLAT IN SHAPE, RESEMBLING A DEMENTED THIN WASHER • USEFUL FOR PREVENTING VIBRATION AND SELF-LOOSENING OF BOLTS • CAN BE STACKED TO INCREASE LOAD OR RESISTANCE MVRT115

  12. Basic Types TORSION SPRINGS • GENERALLY RESEMBLE AN “l” SHAPE WITH A LOOP IN THE MIDDLE • RESISTS ROTATION OF THE TWO ENDS IN OPPOSITE DIRECTION • CAN BE WOUND CLOCKWISE OR COUNTERCLOCKWISE TO RESIST COMPRESSION OR EXTENSION (ROTATIONAL) MVRT115

  13. GEARS

  14. Basic Types BEVEL GEARS • GEAR WITH TEETH ON A 45 DEGREE SLANTED ANGLE • ENABLES MESHING OF TEETH AT A 90 DEGREE INTERSECTION MVRT115

  15. Basic Types MITER GEARS • GEAR WITH TEETH ON A 45 DEGREE SLANTED ANGLE • ENABLES MESHING OF TEETH AT A 90 DEGREE INTERSECTION • GEARS MUST BE EXACTLY THE SAME MVRT115

  16. Basic Types SPUR GEARS • WORK WITH RACK TO PROVIDE HORIZONTAL MOTION MVRT115

  17. Basic Types WORM GEAR • RESEMBLES A CYLINDER ITH THREADS RUNNING LENGTH-WISE VS. DIAMETER-WISE • CANNOT BE TURNED BY OTHER NORMAL GEARS (PREVENTS BACKDRIVE) • GENERALLY DOES NOT CHANGE GEAR RATIO VERY MUCH IF AT ALL MVRT115
