Linear Slide

A metal bar with angled sides that allow plastic sliders, or "trucks," to slide along its length without falling off.

Cam & Follower

A pear-shaped disk with an off-center pivot point, used to change rotating motion into reciprocating motion.

standoff

Used in mechanics to separate 2 parts from one another

Torque

a turning or twisting force

bolt

fastening pin or screw

Input Gear has 48 teeth and output 12 teeth what is the gear ratio?

1:4

Input Gear has 12 teeth and output 24 teeth what is the gear ratio?

2:1

Input Gear has 4 teeth and output 36 teeth what is the gear ratio?

9:1

gear

A circular toothed object used to transfer rotary motion and torque through interlocking teeth.

Simple Gear Train

A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide.

Bearing Flat

A commonly used type of bearing in the VEX system. This bearing has three holes in a row. An axle is passed through the center hole which allows it to spin freely.

Universal Joint

A joint that allows connected shafts to spin freely while permitting a change in direction.

Worm and Wheel

A mechanical arrangement consisting of a toothed wheel driven by a short revolving cylinder bearing a screw thread.

Crank and Slider

A mechanism that consists of an arm attached to a rotating component which converts a rotational input motion to a different type of output motion.

Angle

A piece of hardware shaped like a letter "L" and used to brace objects.

Gusset

A plate or bracket for strengthening an angle in framework.

Rack and Pinion

A rotating gear that meshes with a bar that has gear teeth along its length. Changes rotating motion into linear motion.

KEPS Nut

A standard nut that includes a toothed "crown" designed to bite into a mounting surface and prevent the nut from slipping.

Lead Screw

A threaded shaft used to convert rotary movement to linear movement.

Sprocket

A toothed wheel whose teeth engage the links of a chain.

Oscillating motion

Back and forth movement in an arc.

Speed vs Torque

Directly relational to each other where an increase in one equals a decrease in the other.

Rubber Shaft Collar

Holds objects on shafts and/or the shaft itself in place.

drive shaft

The connecting component that carries torque and transmits rotation

Rail

This part is a versatile angle with one narrow side and one taller side

Robots original use

Three D's Dirty, Dangerous, and Dull

wrench

Tool used to hold mechanical nut in place

Chain Drive

a device that provides rotational energy to driven equipment by means of a series of sprocket wheels that interlink with a chain; designed for low speeds and high-torque conversions

Bevel Gear

a gear working another gear at an angle to it by means of bevel wheels.

screwdriver

a hand tool for driving screws

Belt Drive

a mechanism in which power is transmitted by a continuous flexible belt.

Gear Ratio

compare the driven gear to the drive gear

More torque equals

less speed

more speed equals

less torque

Reciprocating motion

linear back and forth motion

Simple Gear Train with Idler

makes the drive and the driven turn in the same direction, parallel axles

Rotary Motion

movement around in a circle

Meshed gears always turn in (opposite/same)

opposite

Rack Gearbox Bracket

provide support for several options of advanced motion

Drive Gear

the input gear

Driven Gear

the output gear

Shaft Collar

Locks on drive shafts, keeping wheels and gears from sliding along the shaft

linear motion

Movement in a straight line in one direction.

Push Rivet

Plastic piece used to quickly attach bearing flat to metal substructure

Spacers

Small plastic pieces used to space objects and drive shafts away from other pieces or to help line up objects
