Relationship among Linear Speed, Rotational Speed and Gear Radius

1, and the angular velocity indicates the rotation speed of the rigid body.

Symbol: ω, unit: radian/second

2. Speed: Speed is expressed in revolutions per minute.

Symbol: n, unit: rpm.

Conversion relationship between angular velocity and rotational speed;

Ω = 2π n/60 (radian/second) =30πn/30 (radian/second)

3. The speed at which a particle moves in a circle along its tangent direction, also known as the circumferential speed. Symbol: v, unit: m/s.

Relationship between linear velocity and angular velocity: v = rω.

Then the relationship between linear speed and rotational speed: v = rω =πnd(m/s)

The velocity distribution law of each point on a rotating rigid body is linear.

Gear is a kind of mechanical element, whose rim continuously meshes with gear to transmit motion and power. The application of gears in transmission appeared very early. At the end of 19, the principle of generating tooth cutting and the special machine tools and tools for tooth cutting using this principle appeared one after another. With the development of production, the stability of gear operation has been paid more and more attention.

Change:

Low carbon has become the theme of manufacturing development. With more and more countries making low-carbon commitments, energy conservation and emission reduction will be the next technological development direction of enterprises. The industry should also seize the opportunity of low-carbon economy and intervene in the research of new energy technologies such as hybrid power, fuel cell, electromechanical electronics in advance; Further tap the potential of traditional energy, vigorously develop technologies such as remanufacturing, and promote the green development and circular development of the industry.
