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.

Common spur gear specifications

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.
