large casting steel gear ring spur gear girth gear for mining
machine
Spur gears are widely accepted as the most efficient type of
gearing solution, when the application of transmitting power and
uniform rotary motion from one parallel shaft to another is
required. Determined by the center distance, spur gears create a
steady functioning speed drive. This drive speed can be decreased
or increased by the variable number of teeth that exist in the
driving gear.
Several of our custom spur gears have been used in gear train
applications - where multiple gears are required to have the same
pressure angle and diameter pitch. They are available in plastic,
non-metallic, brass, steel and cast iron. In addition ,these parts
are manufactured many style types: plain, web, web with lightening
holes, and web with spokes. Many are available with or without
hubs.
