The different modules of the TCS are the following. Understanding the design principles of each allows one to use off-the-shelf parts to build heavy equipment.

  • Structure - perfotared box tubing. Types of mounting plates. 1/4 and 1/2" tubing. Calculations. Bonding tubing together: stacking in 2 dimensions; extension; joining at an angle.
  • Nuts and Bolts - nuts, bolts, washers, lock washers, drilled nuts, thread types (r,l, s, f), nylon lock nuts, loctite, grades, sizes. Head types. Washers as spacers. Washers for pins. Cotter pin. Pin. Bolt as pin.
  • Motor Mounting - via flange. Via Bearings at two points. Direct shaft attachment. Quick shaft attachment via splined shafts. Splined shaft release pin. Shaft clamp collars. Mounting plates. Right angle mounting plates. Structural calculations. Boot strength calculations. Chain couplers. Sprockets and chain. Geardown. Blade monting. Shear pins.
  • Shafts and Pivots. Shaft sizes. Shaft Pivots. Arm joint design. Types of steel used. Pivot plates. Clamp collars. Shaft mounting ng to frame.
