Description

Worm gears are a category of helical rolling gears that are classified as transmission or
conversion elements within machine elements. This type of gear comprises the usual driving
worm and the driven worm wheel. Worm gears are quiet and have a damping effect. They
are smaller and easier to operate than spur gears or bevel gears of the same performance
and gear ratios. The SMT-TM-08 experimental unit is used to study their torque ratios and
efficiency. The transmission ratio of the gear can be determined. The basic concepts of
toothing such as tooth number and gear number, module, pitch and centre distance are
illustrated.
