allows the transmission of rotary motion between two parallel or perpendicular lines, changing the characteristics of speed and / or direction of rotation.
Its practical applications are limited because they can not transmit large forces between the axles, because its whole operation is based on the friction that occurs between the two wheels. It is found in the dynamos of the Bicycle transmission systems at wells and rocker movement, player ...
Description
This system consists of two-wheeled solidarity with their axes, whose perimeters are in direct contact. The movement is transmitted from one wheel to another by drag (friction).
From the technical point of view we must consider at least 4 operators:
Driving shaft: having the money we want to convey. Normally be attached to a motor.
wheel driving: solidarity with the driving, pick up the rotation of this which is transmitted by friction (rubbing) to the driven wheel driven gear
: includes the rotation of the driving wheel by friction between them. Shaft driven
: get the rotation of the driven wheel and transmits it to receiver.
