Manuel Transmission

DAY ONE

Manuel Transmission

 Manuel Transmissions.
We have just started on Manuel transmission this week, my partner and I have begun dismantling and trying to understand how a gear box  works and how the gears operate. basically the reason why automotive vehicles have so many gear components is to take the power away from the engine and deliver it to the wheels.



HELICAL TOOTHED GEARS

Helical gear are gears cut at an angle. when the two teeth on a helical gear engage this will cause the contact to start at one end of the tooth and gradually spread as the gears rotate. two mating helical gears must have equal helix angle, but opposite hand this way the run more quieter and smoother they also have higher load capacity and are much more expensive to manufacture.




HERRINGBONE TOOTHED GEARS



The tooth angles of the herringbone gears are reversed on the opposite side, this is to counterbalance the thrust produced by the right or left hand sides. both sets of teeth is separated at the centre by a thin gap for a proper alignment.










STRAIGHT CUT GEARS

Straight cut gears are the most simplest type of gears. unlike helical gears, straight cut gears may make a bit of nose when increasing speed , but offers both direct force allowing  less loss of power and higher load. making the transmission stronger and efficient.
