CCS Certified Alloy Steel Straight Spur Gear For Construction
Machinery
The basic introduction of gears
Gear; A mechanical component with teeth on the rim that can
continuously engage to transfer motion and power is a mechanical
component with teeth that can mesh with each other. The diameter of
the big gear is twice that of the small one. If the big gear does
not move, how many times does the pinion revolve around the big
one? Conversely, if the pinion does not move, how many times does
the big pinion revolve around the pinion? The big gear does not
move, the small gear along the big gear revolution one week, the
small gear rotation one week; When the pinion does not move, the
big gear rotates once around the pinion, and the big gear rotates
once and a half, i.e., once at 240°, once and a half at 360°, two
times at 480°, and three times at 720°.
Gear is a mechanical part with teeth that can mesh with each other.
It is widely used in mechanical transmission and the whole
mechanical field. Modern gear technology has reached: gear modulus
0.004 ~ 100 mm; Gear diameter from 1 mm to 150 meters; Transmission
power up to 100,000 kilowatts; Speed up to hundreds of thousands of
RPM; The highest circumferential speed is 300 m/s.

Role of gears
Gear is a mechanical part with teeth that can mesh with each other.
The application of gear in transmission appeared very early. At the
end of the 19th century, the development of the principle of tooth
cutting method and the use of this principle of tooth cutting
special machine tools and tools have appeared, with the development
of production, the smoothness of gear operation by attention. The
role of gear is to transfer the rotation of one shaft to another
shaft, but also to achieve deceleration, increase, change and
reverse action.
Some technical terms
Teeth -- each raised part of a gear used for meshing. In general,
these bumps are radially arranged. The teeth of paired gears are in
contact with each other, resulting in continuous meshing of gears.
Groove ─ the space in a gear between two adjacent teeth.
End face ─ the plane perpendicular to the axis of a cylindrical
gear or worm on a cylindrical gear or worm.
Normal surface -- In gears, normal surface is the plane
perpendicular to the tooth line.
Apex circle ─ the circle where the tip of the tooth is located.
Root circle ─ the circle where the bottom of the groove is located.
Base circle ─ a circle on which an involute line is formed and on
which a pure roll is made.
Indexing circle ── reference circle for calculating gear geometry
in the end face. For spur gears, the modulus and pressure Angle on
the indexing circle are standard values.
Tooth surface ─ the side surface of the tooth between the top and
root cylinders.
Profile ─ the line at which the tooth surface is cut by a specified
surface (plane for cylindrical gears).
Tooth line ─ intersection line between tooth surface and indexing
cylinder surface.
End pitch PT -- the dividing arc length between the same end
profile of two adjacent teeth.
Modulus m - the quotient of pitch divided by PI, in millimeters.
Pitch P -- Reciprocal of modulus, in inches.
