3.ROTARY TRANSMITION

Rotary transmission systems put two rotating elements into contact. These mechanisms have two purposes:

-Transferring rotary force from an input location to another location.

-Changing the rotary speed by using rotating elements of different sizes.

We can forme these functions with various mechanisms, such as the following:

                                                               FRICTION WHEELS

                                            

                                                            PULLEYS WITH BELTS

                                            

                                                            INTERLOCKING GEARS

                                           

                                                            SPROCKETS WITH CHAINS

                                                        

All of these mechanismskeep the same speed ratios, but each one has a different advantage.
