Worm
Gears The
specialty of a worm gear and worm wheel is that they provide a large speed
ratio but with significant sliding. Another feature being of the worm gear is
that most of the designs are non reversible . Worm
Gears are suited for - right
angle skew shafts,
- high
velocity ratio ,
- higher
speeds and loads.
Although
worm gears can be standardized for high precision, they have their own limitations.
Worm Gears can be at best considered for average precision meshes, but
for works of high precision they have to be selected with care. They are probably
the apt choice for a combination of high velocity ratio and right angle drive.
Excellent lubrication should always be ensured in use of worm
gears since high sliding requires ,lubrication at all times. |
