RUSH GEARS inc. manufactures custom spur gears based on your 2D drawings,3D models, or old, worn out parts or samples.
We will manufacture them out of the material YOU specify or we will take your sample gear and have it tested
to determine the material and hardness.
Either way you will recieve a custom spur gear manufactured to your custom needs.
RUSH GEARS inc. Spur Gears are designed to operate on parallel
shafts to transmit motion and power. RUSH GEARS inc. offers the
largest selection in industry today.
Spur Gears are the most popular form and the most efficient type of
gearing for the cost when transmitting power and uniform rotary
motion from one parallel shaft to another. Within the limitations of
center distance, spur gears provide a positive, constant speed drive,
the speed of which may be increased or decreased by increasing or
decreasing the number of teeth in the driving gear.
Spur Gears may be operated in a “gear-train” of two or more gears
but they must all be of the same diametral pitch and pressure angle.
Gears with 14-1/2° pressure angle will not operate with those cut to
20° pressure angle.
RUSH GEARS inc. SPUR GEARS are available in eight materials:
STEEL, HARDENED TEETH, CAST IRON, BRONZE, STAINLESS
STEEL, ALUMINUM, NYLON, NON-METALLIC PHENOLIC. Gears
made of custom materials to customer specifications can be
Pitch line velocity of metallic gears should not exceed 1200 feet per
minute. Where noise is a factor, but higher speeds cannot be
avoided it is recommended that a nylon or non-metallic gear be used
and operated up to speeds of 2400 feet per minute preventing much
of the noise and vibration caused by metal to metal contact.
All critical surfaces of RUSH GEARS inc. SPUR GEARS are
precision machined to close tolerances. Change Gears, Pinion Wire,
Stem Pinions, Internal Gears and Rack are all spur gears of various
types able to operate together since each has the same straight
involute tooth form.
