	My Use of Lego Gears
		There is a lot of friction (destructive friction) between a worm gear and the gear being driven by the worm gear.
		With worm gears, the surface of the helical teeth slide against the radial teeth of the spur gear (24-toothed, 40-toothed, etc.).
		Gears of the same size will vary in strength such that one set of gears may fail in a given situation, whereas another set may hold up.

	Howstuffworks "How Gear Ratios Work"
		Gear trains often consist of multiple gears in the train, as shown in the next two figures.
		In this train, the smaller gears are one-fifth the size of the larger gears.
		That means that if you connect the purple gear to a motor spinning at 100 revolutions per minute (rpm), the green gear will turn at a rate of 500 rpm and the red gear will turn at a rate of 2,500 rpm.

		High gear: gear 2 shifted so that clutch teeth on end of gear 2 mesh with clutch teeth on end of gear 1.
		Gear 2 is drivew by a 63-tooth gear (not shown) which operates at 2400 rpm.
		At low speed, gear 7 is held stationary and shaft B is connected to the supercharger shaft with the same gear ratio as was used between gear 2 and the supercharger shaft.

		, of a gear train relates the output velocity to the input velocity.
		The train ratio for a simple gear train is the ratio of the number of teeth on the input gear to the number of teeth on the output gear (equation 9.7 in text).
		A common approach to the design of compound gear trains is to first determine the number of gear reduction steps needed (each step is typically smaller than 10:1 for size purposes).

		The gear train also had to be compact so as to make the model as realistic as possible and to reduce the number (hence weight) of the lego blocks used.
		In this situation, the high speed gear train would have no effect in the beginning because it would not have enough tourque to move the bike, and in essence the low torque gear train would be doing all of the work.
		Then as the bike pickes up speed and overcomes inertia, the high speed gear train would automatically kick in and begin to contribute to the bike's top speed because the bike would then be at a velocity where the high speed gear train's low tourque would not be a hinderence.

	Gear Train Rebuild
		The gear train rebuild should always be started at the 7+000 KC position.
		Removing the gear to the right of the KC shaft will require loosening the gear clamp behind the aluminum panel, and pulling its shaft through the panel bearing.
		It is this gear shaft that couples the rest of the gear train to the RF bandswitch intermittent gear.

		Gear and gear train types can be grouped based on their application and tooth geometry.
		For bevel gears, the pitch surface is a cone, (it was a cylinder in spur and helical gears) and mating spiral gears can be modeled as two cones in rolling contact.
		The pitch surface of a hypoid gear is a hyperboloid of revolution (rather than a cone, the pitch surface in bevel gears), hence the name.

	Planetary Gears
		A pair of spur gears is represented in the diagram by their pitch circles, which are tangent at the pitch point P. The meshing gear teeth extend beyond the pitch circle by the addendum, and the spaces between them have a depth beneath the pitch circle by the dedendum.
		The velocity ratio r of a pair of gears is the ratio of the angular velocity of the driven gear to the angular velocity of the driving gear.
		The velocity ratio of the gears does not depend on the exact spacing of the axes, but is fixed by the number of teeth, or what is the same thing, by the pitch diameters.

	Lego Gear Trains
		When two gears mesh with each other, the linear velocity of the point of contact is the same for both gears.
		Since the linear velocity of a gear at the surface is proportional to the radius and the angular velocity of the gear, the smaller gear must spin faster than the larger gear to make up for it's lack of radius.
		Depending on which gear the shifter comes into contact with, a different spin ratio is created for the whole system.

		A 78-tooth spur gear is in mesh with a 27-tooth pinion.
		Note the torque is the not same for both the pinion and the gear (we ignore the 1-3% losses in the transmission), but the tangential force is! The torque ratio is the same as the gear ratio.
		That is the gear ratio is 12:1 or 12 to 1.

	Howstuffworks "How Gears Work"
		Gears are used in tons of mechanical devices.
		For instance, an electric screwdriver has a very large gear reduction because it needs lots of torque to turn screws, but the motor only produces a small amount of torque at a high speed.
		For instance, in the differential between the rear wheels of your car, the power is transmitted by a shaft that runs down the center of the car, and the differential has to turn that power 90 degrees to apply it to the wheels.

		In this compound gear train, a third gear wheel is fixed to one of the gear wheels, and a fourth gear is free to turn about the other shaft.
		Thus, two gears on one shaft rotate in sync while the other pair rotates relative to one another on the other shaft.
		Gear trains have many applications in rotating machinery, including transmission units in automobiles and trucks.

		The main components of the assembly are the lever arms, the planetary gear train, the base assembly, and the powertrain.
		The base is what ties the 6 arms and the gear train together, and also provides an interface between the ride and the motors attached to the ground, where the powertrain is located.
		The reason I had to modify it was because of the fact that the planetary gear train is attached to the ground.

		However implementing a drive train to supply drive enables you to mount motors away from the wheel, add gearing to suit specific requirements, and provide mechanically consistent drive to each wheel.
		You can think of gears as leavers whose fulcrum is their axle and whose application points are their teeth.
		Thus applying the same force to a larger gear (that is to a longer leaver) results in an increase in torque.

		Using two of large pins, attach two gears of the same size on your board so that the teeth mesh, and an arrow on each gear is matched up with the line on your foamboard.
		Use one finger on the smaller gear to turn the gear train and have a team member lightly touch the driven gear on the top close to the outside (near the teeth), and then increase downward pressure on the gear while it is turning.
		A driven gear transmits a torque to its axle, which depends on the force applied to its teeth and the radius of the driven gear.

		The central gear of one element is an external gear; the central gear of the other element is an internal gear.
		More complex epicyclic trains may be analysed in a similar manner, but the technique is not of much assistance when the problem is one of gear train design - the interested designer is referred to the Bibliography.
		The train is analysed via equations (2) applied to the two elements in turn, together with the appropriate equations which set out the velocity and torque constraints across the interface between the two elements 1-2-arm and 3-4-arm.

	Automobile Differential Gears
		When the car is moving in a straight line, the differential gears do not rotate with respect to their axes.
		The gear train in an automobile differential is a common application of gears, but often misunderstood by the lay public.
		Driven wheels connected to the engine via the driveshaft, however, must both be turned by gearing and this gear train must allow for differential movement of the left wheel with respect to the right wheel.
