Gears
are the mechanically rotating devices with
engaged teeth. Gears are
free to rotate at a fixed point. These gears
are able to change their direction of motion,
speed and power between the output and input
shaft. Gears are always
worked in pairs. Gears
handle pressure angle and direction. Herringbone
Gears is one of the types of gears.
Herringbone gears is the
combinations of two helical gears
of different hands. Herringbone
Gears transmit powers and motions
between the parallel axes with two opposing
helices with may or may not have central
groove. The two helix angle forms a ‘v’
in the centre of the gears face. They can
handle load smoothly and transmit high power.
Herringbone gears are used
for heavy machineries and of high precision.
Herringbone gears are
used in power transmission. It includes
mounting and material of construction. Material
can be metal or plastic. They offer better
performance than any other gears with low
maintenance, less vibration and noise and
many more. A hub is mounted on the herringbone
gears. It is of cylindrical in
shape with protection on one or both sides
of the gear. Herringbone gears
specify a number of parameter like number
of teeth, outside diameter, and pitch diameter. |
